They had arrived in San Francisco, where their ship was decommissioned, and Paul bet that he would find himself a wife within two weeks. He was a taut, tattooed engine mechanic, six feet tall, with a passing resemblance to James Dean. But it wasn’t his looks that got him a date with Clara Hagopian, a sweet-humored daughter of Armenian immigrants. It was the fact that he and his friends had a car, unlike the group she had originally planned to go out with that evening. Ten days later, in March 1946, Paul got engaged to Clara and won his wager. It would turn out to be a happy marriage, one that lasted until death parted them more than forty years later. Paul Reinhold Jobs had been raised on a dairy farm in Germantown, Wisconsin. Even though his father was an alcoholic and sometimes abusive, Paul ended up with a gentle and calm disposition under his leathery exterior. After dropping out of high mechanic until, at age nineteen, he joined the Coast Guard, even though he didn’t know how to swim. He was deployed on the USS General M. C. Meigs and spent much of the war ferrying troops to Italy for General Patton. His talent as a machinist and fireman earned him commendations, but he occasionally found himself in minor trouble and never rose above the rank of seaman. Clara was born in New Jersey, where her parents had landed after fleeing the Turks in Armenia, and they moved to the Mission District of San Francisco when she was a child. She had a secret that she rarely mentioned to anyone: She had been married before, but her husband had been killed in the war. So when she met Paul Jobs on that first date, she was primed to start a new life. Clara, however, loved San Francisco, and in 1952 she convinced her husband to move back there. They got an apartment in the Sunset District facing the Pacific, just south of Golden Gate Park, and he took a job working for a finance company as a “repo man,” picking the locks of cars whose owners hadn’t paid their loans and repossessing them. He also bought, repaired, and sold some of the cars, making a decent enough living in the process. There was, however, something missing in their lives. They wanted children, but Clara had suffered an ectopic pregnancy, in which the fertilized egg was implanted in a fallopian tube rather than the uterus, and she had been unable to have any. So by 1955, after nine years of marriage, they were looking to adopt a child. Like Paul Jobs, Joanne Schieble was from a rural Wisconsin family of German heritage. Her father, Arthur Schieble, had immigrated to the outskirts of Green Bay, where he and his wife owned a mink farm and dabbled successfully in various other businesses, including real estate and photoengraving. He was very strict, especially regarding his daughter’s relationships, and he had strongly disapproved of her first love, an artist who was not a Catholic. Thus it was no surprise that he threatened to cut Joanne off completely when, as a graduate student at the University of Wisconsin, she fell in love with Abdulfattah “John” Jandali, a Muslim teaching assistant from Syria. Jandali was the youngest of nine children in a prominent Syrian family. His father owned oil refineries and multiple other businesses, with large holdings in Damascus and Homs, and at one point pretty much controlled the price of wheat in the region. His mother, he later said, was a “traditional Muslim woman” who was a “conservative, obedient housewife.” Like the Schieble family, the Jandalis put a premium on education. Abdulfattah was sent to a Jesuit boarding school, even though he was Muslim, and he got an undergraduate degree at the American University in Beirut before entering the University of Wisconsin to pursue a doctoral degree in political science. In the summer of 1954, Joanne went with Abdulfattah to Syria. They spent two months in Homs, where she learned from his family to cook Syrian dishes. When they returned to Wisconsin she discovered that she was pregnant. They were both twenty-three, but they decided not to get married. Her father was dying at the time, and he had threatened to disown her if she wed Abdulfattah. Nor was abortion an easy option in a small Catholic community. So in early 1955, Joanne traveled to San Francisco, where she was taken into the care of a kindly doctor who sheltered unwed mothers, delivered their babies, and quietly arranged closed adoptions. Joanne had one requirement: Her child must be adopted by college graduates. So the doctor arranged for the baby to be placed with a lawyer and his wife. But when a boy was born—on February 24, 1955—the designated couple decided that they wanted a girl and backed out. Thus it was that the boy became the son not of a lawyer but of a high school dropout with a passion for mechanics and his salt-of-the-earth wife who was working as a bookkeeper. Paul and Clara named their new baby Steven Paul Jobs. When Joanne found out that her baby had been placed with a couple who had not even graduated from high school, she refused to sign the adoption papers. The standoff lasted weeks, even after the baby had settled into the Jobs household. Eventually Joanne relented, with the stipulation that the couple promise—indeed sign a pledge—to fund a savings account to pay for the boy’s college education. There was another reason that Joanne was balky about signing the adoption papers. Her father was about to die, and she planned to marry Jandali soon after. She held out hope, she would later tell family members, sometimes tearing up at the memory, that once they were married, she could get their 别让梦想只停留在梦里。181.

Arthur Schieble died in August 1955, after the adoption was finalized. Just after Christmas that year, Joanne and Abdulfattah were married in St. Philip the Apostle Catholic Church in Green Bay. He got his PhD in international politics the next year, and then they had another child, a girl named Mona. After she and Jandali porced in 1962, Joanne embarked on a dreamy and peripatetic life that her daughter, who grew up to become the acclaimed novelist Mona Simpson, would capture in her book Anywhere but Here. Because Steve’s adoption had been closed, it would be twenty years before they would all find each other. Steve Jobs knew from an early age that he was adopted. “My parents were very open with me about that,” he recalled. He had a vivid memory of sitting on the lawn of his house, when he was six or seven years old, telling the girl who lived across the street. “So does that mean your real parents didn’t want you?” the girl asked. “Lightning bolts went off in my head,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eye. They said, ‘We specifically picked you out.’ Both of my parents said that and repeated it slowly for me. And they put an emphasis on every word in that sentence.” Abandoned. Chosen. Special. Those concepts became part of who Jobs was and how he regarded himself. His closest friends think that the knowledge that he was given up at birth left some scars. “I think his desire for complete control of whatever he makes derives directly from his personality and the fact that he was abandoned at birth,” said one longtime colleague, Del Yocam. “He wants to control his environment, and he sees the product as an extension of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned and the pain that caused,” he said. “It made him independent. He followed the beat of a different drummer, and that came from being in a different world than he was born into.” Later in life, when he was the same age his biological father had been when he abandoned him, Jobs would father and abandon a child of his own. (He eventually took responsibility for her.) Chrisann Brennan, the mother of that child, said that being put up for adoption left Jobs “full of broken glass,” and it helps to explain some of his behavior. “He who is abandoned is an abandoner,” she said. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to both Brennan and Jobs. “The key question about Steve is why he can’t control himself at times from being so reflexively cruel and harmful to some people,” he said. “That goes back to being abandoned at birth. The real underlying problem was the theme of abandonment in Steve’s life.” Jobs dismissed this. “There’s some notion that because I was abandoned, I worked very hard so I could do well and make my parents wish they had me back, or some such nonsense, but that’s ridiculous,” he insisted. “Knowing I was adopted may have made me feel more independent, but I have never felt abandoned. I’ve always felt special. My parents made me feel special.” He would later bristle whenever anyone referred to Paul and Clara Jobs as his “adoptive” parents or implied that they were not his “real” parents. “They were my parents 1,000%,” he said. When speaking about his biological parents, on the other hand, he was curt: “They were my sperm and egg bank. That’s not harsh, it’s just the way it was, a sperm bank thing, nothing more.” Silicon Valley The childhood that Paul and Clara Jobs created for their new son was, in many ways, a stereotype of the late 1950s. When Steve was two they adopted a girl they named Patty, and three years later they moved to a tract house in the suburbs. The finance company where Paul worked as a repo man, CIT, had transferred him down to its Palo Alto office, but he could not afford to live there, so they landed in a subpision in Mountain View, a less expensive town just to the south. There Paul tried to pass along his love of mechanics and cars. “Steve, this is your workbench now,” he said as he marked off a section of the table in their garage. Jobs remembered being impressed by his father’s focus on craftsmanship. “I thought my dad’s sense of design was pretty good,” he said, “because he knew how to build anything. If we needed a cabinet, he would build it. When he built our fence, he gave me a hammer so I could work with him.” Fifty years later the fence still surrounds the back and side yards of the house in Mountain View. As Jobs showed it off to me, he caressed the stockade panels and recalled a lesson that his father implanted deeply in him. It was important, his father said, to craft the backs of cabinets and fences properly, even though they were hidden. “He loved doing things right. He even cared about the look of the parts you couldn’t see.” His father continued to refurbish and resell used cars, and he festooned the garage with pictures of his favorites. He would point out the detailing of the design to his son: the lines, the vents, the chrome, the trim of the seats. After work each day, he would change into his dungarees and retreat to the garage, often with Steve tagging along. “I figured I could get him nailed down with a little mechanical ability, but he really wasn’t interested in getting his hands dirty,” Paul later recalled. “He never really cared too much about m189.

One day when he was about eight, he discovered a photograph of his father from his time in the Coast Guard. “He’s in the engine room, and he’s got his shirt off and looks like James Dean. It was one of those Oh wow moments for a kid. Wow, oooh, my parents were actually once very young and really good-looking.” Through cars, his father gave Steve his first exposure to electronics. “My dad did not have a deep understanding of electronics, but he’d encountered it a lot in automobiles and other things he would fix. He showed me the rudiments of electronics, and I got very interested in that.” Even more interesting were the trips to scavenge for parts. “Every weekend, there’d be a junkyard trip. We’d be looking for a generator, a carburetor, all sorts of components.” He remembered watching his father negotiate at the counter. “He was a good bargainer, because he knew better than the guys at the counter what the parts should cost.” This helped fulfill the pledge his parents made when he was adopted. “My college fund came from my dad paying $50 for a Ford Falcon or some other beat-up car that didn’t run, working on it for a few weeks, and selling it for $250—and not telling the IRS.” The Jobses’ house and the others in their neighborhood were built by the real estate developer Joseph Eichler, whose company spawned more than eleven thousand homes in various California subpisions between 1950 and 1974. Inspired by Frank Lloyd Wright’s vision of simple modern homes for the American “everyman,” Eichler built inexpensive houses that featured floor-to-ceiling glass walls, open floor plans, exposed post-and-beam construction, concrete slab floors, and lots of sliding glass doors. “Eichler did a great thing,” Jobs said on one of our walks around the neighborhood. “His houses were smart and cheap and good. They brought clean design and simple taste to lower-income people. They had awesome little features, like radiant heating in the floors. You put carpet on them, and we had nice toasty floors when we were kids.” Jobs said that his appreciation for Eichler homes instilled in him a passion for making nicely designed products for the mass market. “I love it when you can bring really great design and simple capability to something that doesn’t cost much,” he said as he pointed out the clean elegance of the houses. “It was the original vision for Apple. That’s what we tried to do with the first Mac. That’s what we did with the iPod.” Across the street from the Jobs family lived a man who had become successful as a real estate agent. “He wasn’t that bright,” Jobs recalled, “but he seemed to be making a fortune. So my dad thought, ‘I can do that.’ He worked so hard, I remember. He took these night classes, passed the license test, and got into real estate. Then the bottom fell out of the market.” As a result, the family found itself financially strapped for a year or so while Steve was in elementary school. His mother took a job as a bookkeeper for Varian Associates, a company that made scientific instruments, and they took out a second mortgage. One day his fourth-grade teacher asked him, “What is it you don’t understand about the universe?” Jobs replied, “I don’t understand why all of a sudden my dad is so broke.” He was proud that his father never adopted a servile attitude or slick style that may have made him a better salesman. “You had to suck up to people to sell real estate, and he wasn’t good at that and it wasn’t in his nature. I admired him for that.” Paul Jobs went back to being a mechanic. His father was calm and gentle, traits that his son later praised more than emulated. He was also resolute. Jobs described one exampl What made the neighborhood different from the thousands of other spindly-tree subpisions across America was that even the ne’er-do-wells tended to be engineers. “When we moved here, there were apricot and plum orchards on all of these corners,” Jobs recalled. “But it was beginning to boom because of military investment.” He soaked up the history of the valley and developed a yearning to play his own role. Edwin Land of Polaroid later told him about being asked by Eisenhower to help build the U-2 spy plane cameras to see how real the Soviet threat was. The film was dropped in canisters and returned to the NASA Ames Research Center in Sunnyvale, not far from where Jobs lived. “The first computer terminal I ever saw was when my dad brought me to the Ames Center,” he said. “I fell totally in love with it.” Other defense contractors sprouted nearby during the 1950s. The Lockheed Missiles and Space Division, which built submarine-launched ballistic missiles, was founded in 1956 next to the NASA Center; by the time Jobs moved to the area four years later, it employed twenty thousand people. A few hundred yards away, Westinghouse built facilities that produced tubes and electrical transformers for the missile systems. “You had all these military companies on the cutting edge,” he recalled. “It was mysterious and high-tech and made living here very exciting.” In the wake of the defense industries there arose a booming economy based on technology. Its roots stretched back to 1938, when David Packard and his new wife moved into a house in Palo Alto that had a shed where his friend Bill Hewlett was soon ensconced. The house had a garage—an appendage that would prove both useful and iconic in the valley—in which they tinkered around until they had their first product, an audio oscillator. By the 1950s, Hewlett-Packard was a fast-growing company making technical instruments. Fortunately there was a place nearby for entrepreneurs who had outgrown their garages. In a move that would help transform the area into the cradle of the tech revolution, Stanford University’s dean of engineering, Frederick Terman, created a seven-hundred-acre industrial park on university land for private companies that could commercialize the ideas of his students. Its first tenant was Varian Associates, where Clara Jobs worked. “Terman came up with this great idea that did more than anything to cause the tech industry to grow up here,” Jobs said. By the time Jobs was ten, HP had nine thousand employees and was the blue-chip company where every engineer seeking financial stability wanted to work. The most important technology for the region’s growth was, of course, the semiconductor. William Shockley, who had been one of the inventors of the transistor at Bell Labs in New Jersey, moved out to Mountain View and, in 1956, started a company to build transistors using silicon rather than the more expensive germanium that was then commonly used. But Shockley became increasingly erratic and abandoned his silicon transistor project, which led eight of his engineers—most notably Robert Noyce and Gordon Moore—to break away to form Fairchild Semiconductor. That company grew to twelve thousand employees, but it fragmented in 1968, when Noyce lost a power struggle to become CEO. He took Gordon Moore and founded a company that they called Integrated Electronics Corporation, which they soon smartly abbreviated to Intel. Their third employee was Andrew Grove, who later would grow the company by shifting its focus from memory chips to microprocessors. Within a few years there would be more than fifty companies in the area making semiconductors. The exponential growth of this industry was correlated with the phenomenon famously discovered by Moore, who in 1965 drew a graph of the speed of integrated circuits, based on the number of transistors that could be placed on a chip, and showed that it doubled about every two years, a trajectory that could be expected to continue. This was reaffirmed in 1971, when Intel was able to etch a complete central processing unit onto one chip, the Intel 4004, tronic amplifier. “So I raced home, and I told my dad that he was wrong.” “No, it needs an amplifier,” his father assured him. When Steve protested otherwise, his father said he was crazy. “It can’t work without an amplifier. There’s some trick.” “I kept saying no to my dad, telling him he had to see it, and finally he actually walked down with me and saw it. And he said, ‘Well I’ll be a bat out of hell.’” Jobs recalled the incident vividly because it was his first realization that his father did not know everything. Then a more disconcerting discovery began to dawn on him: He was smarter than his parents. He had always admired his father’s competence and savvy. “He was not an educated man, but I had always thought he was pretty damn smart. He didn’t read much, but he could do a lot. Almost everything mechanical, he could figure it out.” Yet the carbon microphone incident, Jobs said, began a jarring process of realizing that he was in fact more clever and quick than his parents. “It was a very big moment that’s burned into my mind. When I realized that I was smarter than my parents, I felt tremendous shame for having thought that. I will never forget that moment.” This discovery, he later told friends, along with the fact that he was adopted, made him feel apart—detached and separate—from both his family and the world. Another layer of awareness occurred soon after. Not only did he discover that he was brighter than his parents, but he discovered that they knew this. Paul and Clara Jobs were loving parents, and they were willing to adapt their lives to suit a son who was very smart—and also willful. They would go to great lengths to accommodate him. And soon Steve discovered this fact as well. “Both my parents got me. They felt a lot of responsibility once they sensed that I was special. They found ways to keep feeding me stuff and putting me in better schools. They were willing to defer to my needs.” So he grew up not only with a sense of having once been abandoned, but also with a sense that he was special. In his own mind, that was more important in the formation of his personality. School Even before Jobs started elementary school, his mother had taught him how to read. This, however, led to some problems once he got to school. “I was kind of bored for the first few years 在这种情况下，俄罗斯和欧洲正兴建一条新的天然气运输管道，这就是北溪-2项目，这个项目全长1224公里，从俄罗斯穿过波罗的海，将天然气运输到德国和其它国家，欧洲很多国家都参与了这条管道项目的建设，毕竟这是欧洲国家的民生工程。一旦这条管道建设完成，可以为欧洲提供每年330亿立方米的天然气，可以满足欧洲对天然气十分之一的需求，这可是非常大的。它是气态行星没有实体表面，由90%的氢和10%的氦（原子数之比, 75/25%的质量比）及微量的甲烷、水、氨水和“石头”组成。这与形成整个太阳系的原始的太阳系星云的组成十分相似。木星可能有一个石质的内核，相当于10－15个地球的质量。内核上则是大部分的行星物质集结地，以液态氢的形式存在。液态金属氢由离子化的质子与电子组成（类似于太阳的内部，不过温度低多了）。木星共有67颗木卫。按距离木星中心由近及远的次序为：木卫十六、木卫十四、木卫五、木卫十五、木卫一、木卫二、木卫三、木卫四、木卫十三、木卫六、木卫十、木卫七、木卫十二、木卫十一、木卫八和木卫九。[46] 水星是最接近太阳的行星。水星的半径约为2440公里，在八大行星中是最小的。水星昼夜温差极大，白天摄氏 430 度，晚上约可达零下170 度，是太阳系八大行星中温差最大的一个行星。[47]  水星的外大气层非常稀薄，是由水星表面和太阳风中的原子和离子构成。[48]  科学家确认水星表面含有丰富的碳，认为碳是水星表面呈黑色的原因，水星表面的岩石是由低重量百分比的石墨碳构成。[49] “好奇号”火星探测器在火星表面采集样本 “好奇号”火星探测器在火星表面采集样本 [50] 火星是地球的近邻，是太阳系由内往外数第四颗行星。直径6794km，体积为地球的15%，质量为地球的11%。火星表面是一个荒凉的世界，空气中二氧化碳占了95%。火星大气十分稀薄，密度还不到地球大气的1%，因而根本无法保存热量。这导致火星表面温度极低，很少超过0℃，在夜晚，最低温度则可达到-123℃。火星被称为红色的行星，这是因为它表面布满了氧化物，因而呈现出铁锈红色。其表面的大部分地区都是含有大量的红色氧化物的大沙漠，还有赭色的砾石地和凝固的熔岩流。火星上常常有猛烈的大风，大风扬起沙尘能形成可以覆盖火星全球的特大型沙尘暴。每次沙尘暴可持续数个星期。火星两极的冰冠和火星大气中含有水份。从火星表面获得的探测数据证明，在远古时期八颗行星，直径49532千米。海王星绕太阳运转的轨道半径为45亿千米，公转一周需要165年。海王星的直径和天王星类似，质量比天王星略大一些。海王星和天王星的主要大气成分都是氢和氦，内部结构也极为相近，所以说海王星与天王星是一对孪生兄弟。[55]  海王星有太阳系最强烈的风，测量到的时速高达2100公里。海王星云顶的温度是－218 °C，是太阳系最冷的地区之一。海王星核心的温度约为7000 °C，可以和太阳的表面比较。海王星在1846年9月23日被发现，是唯一利用数学预测而非有计划的观测发现的行星。[56] 冥王星，位于海王星以外的柯伊伯带内侧，是柯伊伯带中已知的最大天体。[57]  直径约为2370±20km，是地球直径的18.5%。[58] 2006年8月24日，国际天文学联合会大会24日投票决定，不再将传统九大行星之一的冥王星视为行星，而将其列入“矮行星”。大会通过的决议规定，“行星”指的是围绕太阳运转、自身引力足以克服其刚体力而使天体呈圆球状、能够清除其轨道附近其他物体的天体。在太阳系传统的“九大行星”中，只有水星、金星、地球、火星、木星、土星、天王星和海王星符合这些要求。冥王星由于其轨道与海王星的轨道相交，不符合新的行星定义，因此被自动降级为“矮行星”。[59]  冥王星的表面温度大概在-238到-228℃之间。冥王星的成份由70%岩石和30%冰水混合而成的。地表上光亮的部分可能覆盖着一些固体氮以及少量 卫星拍月球经过地球，可见清晰月球背面 卫星拍月球经过地球，可见清晰月球背面 [60] 的固体甲烷和一氧化碳，冥王星表面的黑暗部分可能是一些基本的有机物质或是由宇宙射线引发的光化学反应。冥王星的大气层主要由氮和少量的一氧化碳及甲烷组成。大气极其稀薄，地面压强只有少量微帕。[61] 地球是离太阳第三颗行星，是我们人类的家乡，尽管地球是太阳系中一颗普通的行星，但它在许多方面都是独一无二的。比如，它是太阳系中唯一一颗面积大部分被水覆盖的行星，也是目前所知唯一一颗有生命存在的星球。质量M=5.9742 ×10^24 公斤，表面温度：t = - 30 ～ +45。[62]  英国科研人员在《天体生物学》杂志上报告说，如果没有小行星撞击等可能剧烈改变环境的事件发生，地球适宜人类居住的时间还剩约17.5亿年，不过人为造成的气候变化可能缩短这一时间。[63] 彗星是由灰尘和冰块组成的太阳系中的一类小天体，绕日运动。[64]  科学家使用探测器对彗星的化学遗留物进行分析，发现其主要成份为氨、甲烷、硫化氢、氰化氢和甲醛。科学家得出结论称，彗星的气味闻起来像是臭鸡蛋、马尿、酒精和苦杏仁的气味综合。[65-66] “67P/楚留莫夫-格拉希门克”彗星 “67P/楚留莫夫-格拉希门克”彗星 [67] 在太阳系的周围还包裹着一个庞大的“奥尔特云”。星云内分布着不计其数的冰块、雪团和碎石。其中的某些会受太阳引力影响飞入内太阳系，这学说，在原有的轨道（或称小天体轨道）上又增加了更多的天体运行轨道。这一模式称每颗行星都沿着一个小轨道作圆周运行，而小轨道又沿着该行星的大轨道绕地球作圆周运动。几百年之后，这一模式的漏洞越来越明显。科学家们又在这个模式上增加了许多轨道，行星就这样沿着一道又一道的轨道作圆周运动。哥白尼想用“现代”（16世纪的）技术来改进托勒密的测量结果，以期取消一些小轨道。在长达近20年的时间里，哥白尼不辞辛劳日夜测量行星的位置，但其测量获得的结果仍然与托勒密的天体运行模式没有多少差别。哥白尼想知道在另一个运行着的行星上观察这些行星的运行情况会是什么样的。基于这种设想，哥白尼萌发了一个念头：假如地球在运行中，那么这些行星的运行看上去会是什么情况呢？这一设想在他脑海里变得清晰起来了。一年里，哥白尼在不同的时间、不同的距离从地球上观察行星，每一个行星的情况都不相同，这是他意识到地球不可能位于星星轨道的中心。经过20年的观测，哥白尼发现唯独太阳的周年变化不明显。这意味着地球和太阳的距离始终没有改变。如果地球不是宇宙的中心，那么宇宙的中心就是太阳。的发现才使牛顿有能力确定运动定律和万有引力定律。哥白尼的日心宇宙体系既然是时代的产物，它就不能不受到时代的限制。反对神学的不彻底性，同时表现在哥白尼的某些观点上，他的体系是存在缺陷的。哥白尼所指的宇宙是局限在一个小的范围内的，具体来说，他的宇宙结构就是今天我们所熟知的太阳系，即以太阳为中心的天体系统。宇宙既然有它的中心，就必须有它的边界，哥白尼虽然否定了托勒玫的“九重天”，但他却保留了一层恒星天，尽管他回避了宇宙是否有限这个问题，但实际上他是相信恒星天球是宇宙的“外壳”，他仍然相信天体只能按照所谓完美的圆形轨道运动，所以哥白尼的宇宙体系，仍然包含着不动的中心天体。但是作为近代自然科学的奠基人，哥白尼的历史功绩是伟大的。确认地球不是宇宙的中心，而是行星之一，从而掀起了一场天文学上根本性的革命，是人类探求客观真理道路上的里程碑。哥白尼的伟大成就，不仅铺平了通向近代天文学的道路，而且开创了整个自然界科学向前迈进的新时代。从哥白尼时代起，脱离教会束缚的自然科学和哲学开始获得飞跃的发展。哥白尼的科学成就，是他所处时代的产物，又转过来推动了时代的发展。顺应时代变化 十五、六世纪的欧洲，正是从封建社会向资本主义社会转变的关键时期，在这一二百年间，社会发生了巨大的变化。14世纪以前的欧洲，到处是四分五裂的小城邦。后来，随着城市工商业的兴起，特别是采矿和冶金业的发展，涌现了许多新兴的大城市，小城邦有了联合起来组成国家的趋势。到 15世纪末叶，在许多国家里都出现了基本上是中央集权的君主政体。当时的波兰不仅有像克拉科夫、波兹南这样的大城市，也有许多手工业兴盛的城

霍乱，上次听说还是在《霍乱时期的爱情》，

书评人说，

“爱情和霍乱一样，迅速扩散，持久蔓延，难以治愈。不管人们是什么肤色、何种出身，霍乱突然蔓延开来，夺走的生命难以计数。”

在新冠没有出现之前，霍乱曾是人类传染病的两个“终极大魔头”——甲类传染病之一，另一个是鼠疫。

此次，霍乱疑似在武大校园出现了！

7月10日，武汉大学医院发布了《加强夏季肠道传染病预防》的温馨提示。

一、夏季是肠道传染病的高发季节，如出现腹泻、呕吐等胃肠道症状，请立即到工学部校医院门诊进行预检分诊，信息登记，工作人员指导及时到中南医院发热门诊就诊。

二、要注意饮食安全，把好病从口入关，做好肠道传染病的预防……

消息一出，留言区哀嚎一片

“大哥！希望结果赶紧出来，和大家说是假消息。我以后不想上午捅嗓子眼，下午捅屁*，求放过……”

“难道以后我们会在体育馆还是操场排着队一个一个脱裤子撅着屁屁肛拭子嘛？！”

“麻烦我睡醒告诉我是假的……从19年到武汉读大学就开始了新冠，我的大学生活已经够无趣了，今年只想正常的进大四准备毕业。”

别这样，我害怕暑假完了回武汉，在学校一个个撅着PG被捅……

还有同学表露出了无比焦躁的心情

大家紧张的心情可以理解，但情况未必有那么糟，因为目前只是一栋宿舍楼的学生进行检测，并不是全校都要检测， 所以大家尚且不必太担心！

甜瓜家的樱花君今早联系了武汉大学医务室，一名工作人员表示：目前检测结果还没有出来，也没有接到通知，具体情况不方便透露。

即便真是霍乱，大家也不必过于恐慌。

虽然由于发病凶险，霍乱是中国法定传染病中少数的几种甲类传染病之一，但随着近年卫生条件的改善，发病率逐年降低，近几年国内每年只有个位数字的霍乱病例报道。

2014年以来，中国无一人因霍乱病死亡。

虽然不必太担心，但此次还是暴露出了一些问题。

湖北武汉等长江中下游地区是霍乱的中高风险地区， 而 包括霍乱在内的腹泻疾病都和“ 卫生环境 ”有很大 的关系。

有知情同学表示，此次出现这种事，是意料之外，也是情理之中，因为似乎工学部宿舍的“住宿条件参差不齐”，而事发宿舍楼的环境让很多人“一言难尽”……

甜瓜没去过，希望武大的同学们留言，

如果真有环境不尽如人意，

希望校方能积极改善，保护大家的健康。

They had arrived in San Francisco, where their ship was decommissioned, and Paul bet that he would find himself a wife within two weeks. He was a taut, tattooed engine mechanic, six feet tall, with a passing resemblance to James Dean. But it wasn’t his looks that got him a date with Clara Hagopian, a sweet-humored daughter of Armenian immigrants. It was the fact that he and his friends had a car, unlike the group she had originally planned to go out with that evening. Ten days later, in March 1946, Paul got engaged to Clara and won his wager. It would turn out to be a happy marriage, one that lasted until death parted them more than forty years later. Paul Reinhold Jobs had been raised on a dairy farm in Germantown, Wisconsin. Even though his father was an alcoholic and sometimes abusive, Paul ended up with a gentle and calm disposition under his leathery exterior. After dropping out of high mechanic until, at age nineteen, he joined the Coast Guard, even though he didn’t know how to swim. He was deployed on the USS General M. C. Meigs and spent much of the war ferrying troops to Italy for General Patton. His talent as a machinist and fireman earned him commendations, but he occasionally found himself in minor trouble and never rose above the rank of seaman. Clara was born in New Jersey, where her parents had landed after fleeing the Turks in Armenia, and they moved to the Mission District of San Francisco when she was a child. She had a secret that she rarely mentioned to anyone: She had been married before, but her husband had been killed in the war. So when she met Paul Jobs on that first date, she was primed to start a new life. Clara, however, loved San Francisco, and in 1952 she convinced her husband to move back there. They got an apartment in the Sunset District facing the Pacific, just south of Golden Gate Park, and he took a job working for a finance company as a “repo man,” picking the locks of cars whose owners hadn’t paid their loans and repossessing them. He also bought, repaired, and sold some of the cars, making a decent enough living in the process. There was, however, something missing in their lives. They wanted children, but Clara had suffered an ectopic pregnancy, in which the fertilized egg was implanted in a fallopian tube rather than the uterus, and she had been unable to have any. So by 1955, after nine years of marriage, they were looking to adopt a child. Like Paul Jobs, Joanne Schieble was from a rural Wisconsin family of German heritage. Her father, Arthur Schieble, had immigrated to the outskirts of Green Bay, where he and his wife owned a mink farm and dabbled successfully in various other businesses, including real estate and photoengraving. He was very strict, especially regarding his daughter’s relationships, and he had strongly disapproved of her first love, an artist who was not a Catholic. Thus it was no surprise that he threatened to cut Joanne off completely when, as a graduate student at the University of Wisconsin, she fell in love with Abdulfattah “John” Jandali, a Muslim teaching assistant from Syria. Jandali was the youngest of nine children in a prominent Syrian family. His father owned oil refineries and multiple other businesses, with large holdings in Damascus and Homs, and at one point pretty much controlled the price of wheat in the region. His mother, he later said, was a “traditional Muslim woman” who was a “conservative, obedient housewife.” Like the Schieble family, the Jandalis put a premium on education. Abdulfattah was sent to a Jesuit boarding school, even though he was Muslim, and he got an undergraduate degree at the American University in Beirut before entering the University of Wisconsin to pursue a doctoral degree in political science. In the summer of 1954, Joanne went with Abdulfattah to Syria. They spent two months in Homs, where she learned from his family to cook Syrian dishes. When they returned to Wisconsin she discovered that she was pregnant. They were both twenty-three, but they decided not to get married. Her father was dying at the time, and he had threatened to disown her if she wed Abdulfattah. Nor was abortion an easy option in a small Catholic community. So in early 1955, Joanne traveled to San Francisco, where she was taken into the care of a kindly doctor who sheltered unwed mothers, delivered their babies, and quietly arranged closed adoptions. Joanne had one requirement: Her child must be adopted by college graduates. So the doctor arranged for the baby to be placed with a lawyer and his wife. But when a boy was born—on February 24, 1955—the designated couple decided that they wanted a girl and backed out. Thus it was that the boy became the son not of a lawyer but of a high school dropout with a passion for mechanics and his salt-of-the-earth wife who was working as a bookkeeper. Paul and Clara named their new baby Steven Paul Jobs. When Joanne found out that her baby had been placed with a couple who had not even graduated from high school, she refused to sign the adoption papers. The standoff lasted weeks, even after the baby had settled into the Jobs household. Eventually Joanne relented, with the stipulation that the couple promise—indeed sign a pledge—to fund a savings account to pay for the boy’s college education. There was another reason that Joanne was balky about signing the adoption papers. Her father was about to die, and she planned to marry Jandali soon after. She held out hope, she would later tell family members, sometimes tearing up at the memory, that once they were married, she could get their 别让梦想只停留在梦里。181.

Arthur Schieble died in August 1955, after the adoption was finalized. Just after Christmas that year, Joanne and Abdulfattah were married in St. Philip the Apostle Catholic Church in Green Bay. He got his PhD in international politics the next year, and then they had another child, a girl named Mona. After she and Jandali porced in 1962, Joanne embarked on a dreamy and peripatetic life that her daughter, who grew up to become the acclaimed novelist Mona Simpson, would capture in her book Anywhere but Here. Because Steve’s adoption had been closed, it would be twenty years before they would all find each other. Steve Jobs knew from an early age that he was adopted. “My parents were very open with me about that,” he recalled. He had a vivid memory of sitting on the lawn of his house, when he was six or seven years old, telling the girl who lived across the street. “So does that mean your real parents didn’t want you?” the girl asked. “Lightning bolts went off in my head,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eye. They said, ‘We specifically picked you out.’ Both of my parents said that and repeated it slowly for me. And they put an emphasis on every word in that sentence.” Abandoned. Chosen. Special. Those concepts became part of who Jobs was and how he regarded himself. His closest friends think that the knowledge that he was given up at birth left some scars. “I think his desire for complete control of whatever he makes derives directly from his personality and the fact that he was abandoned at birth,” said one longtime colleague, Del Yocam. “He wants to control his environment, and he sees the product as an extension of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned and the pain that caused,” he said. “It made him independent. He followed the beat of a different drummer, and that came from being in a different world than he was born into.” Later in life, when he was the same age his biological father had been when he abandoned him, Jobs would father and abandon a child of his own. (He eventually took responsibility for her.) Chrisann Brennan, the mother of that child, said that being put up for adoption left Jobs “full of broken glass,” and it helps to explain some of his behavior. “He who is abandoned is an abandoner,” she said. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to both Brennan and Jobs. “The key question about Steve is why he can’t control himself at times from being so reflexively cruel and harmful to some people,” he said. “That goes back to being abandoned at birth. The real underlying problem was the theme of abandonment in Steve’s life.” Jobs dismissed this. “There’s some notion that because I was abandoned, I worked very hard so I could do well and make my parents wish they had me back, or some such nonsense, but that’s ridiculous,” he insisted. “Knowing I was adopted may have made me feel more independent, but I have never felt abandoned. I’ve always felt special. My parents made me feel special.” He would later bristle whenever anyone referred to Paul and Clara Jobs as his “adoptive” parents or implied that they were not his “real” parents. “They were my parents 1,000%,” he said. When speaking about his biological parents, on the other hand, he was curt: “They were my sperm and egg bank. That’s not harsh, it’s just the way it was, a sperm bank thing, nothing more.” Silicon Valley The childhood that Paul and Clara Jobs created for their new son was, in many ways, a stereotype of the late 1950s. When Steve was two they adopted a girl they named Patty, and three years later they moved to a tract house in the suburbs. The finance company where Paul worked as a repo man, CIT, had transferred him down to its Palo Alto office, but he could not afford to live there, so they landed in a subpision in Mountain View, a less expensive town just to the south. There Paul tried to pass along his love of mechanics and cars. “Steve, this is your workbench now,” he said as he marked off a section of the table in their garage. Jobs remembered being impressed by his father’s focus on craftsmanship. “I thought my dad’s sense of design was pretty good,” he said, “because he knew how to build anything. If we needed a cabinet, he would build it. When he built our fence, he gave me a hammer so I could work with him.” Fifty years later the fence still surrounds the back and side yards of the house in Mountain View. As Jobs showed it off to me, he caressed the stockade panels and recalled a lesson that his father implanted deeply in him. It was important, his father said, to craft the backs of cabinets and fences properly, even though they were hidden. “He loved doing things right. He even cared about the look of the parts you couldn’t see.” His father continued to refurbish and resell used cars, and he festooned the garage with pictures of his favorites. He would point out the detailing of the design to his son: the lines, the vents, the chrome, the trim of the seats. After work each day, he would change into his dungarees and retreat to the garage, often with Steve tagging along. “I figured I could get him nailed down with a little mechanical ability, but he really wasn’t interested in getting his hands dirty,” Paul later recalled. “He never really cared too much about m189.

One day when he was about eight, he discovered a photograph of his father from his time in the Coast Guard. “He’s in the engine room, and he’s got his shirt off and looks like James Dean. It was one of those Oh wow moments for a kid. Wow, oooh, my parents were actually once very young and really good-looking.” Through cars, his father gave Steve his first exposure to electronics. “My dad did not have a deep understanding of electronics, but he’d encountered it a lot in automobiles and other things he would fix. He showed me the rudiments of electronics, and I got very interested in that.” Even more interesting were the trips to scavenge for parts. “Every weekend, there’d be a junkyard trip. We’d be looking for a generator, a carburetor, all sorts of components.” He remembered watching his father negotiate at the counter. “He was a good bargainer, because he knew better than the guys at the counter what the parts should cost.” This helped fulfill the pledge his parents made when he was adopted. “My college fund came from my dad paying $50 for a Ford Falcon or some other beat-up car that didn’t run, working on it for a few weeks, and selling it for $250—and not telling the IRS.” The Jobses’ house and the others in their neighborhood were built by the real estate developer Joseph Eichler, whose company spawned more than eleven thousand homes in various California subpisions between 1950 and 1974. Inspired by Frank Lloyd Wright’s vision of simple modern homes for the American “everyman,” Eichler built inexpensive houses that featured floor-to-ceiling glass walls, open floor plans, exposed post-and-beam construction, concrete slab floors, and lots of sliding glass doors. “Eichler did a great thing,” Jobs said on one of our walks around the neighborhood. “His houses were smart and cheap and good. They brought clean design and simple taste to lower-income people. They had awesome little features, like radiant heating in the floors. You put carpet on them, and we had nice toasty floors when we were kids.” Jobs said that his appreciation for Eichler homes instilled in him a passion for making nicely designed products for the mass market. “I love it when you can bring really great design and simple capability to something that doesn’t cost much,” he said as he pointed out the clean elegance of the houses. “It was the original vision for Apple. That’s what we tried to do with the first Mac. That’s what we did with the iPod.” Across the street from the Jobs family lived a man who had become successful as a real estate agent. “He wasn’t that bright,” Jobs recalled, “but he seemed to be making a fortune. So my dad thought, ‘I can do that.’ He worked so hard, I remember. He took these night classes, passed the license test, and got into real estate. Then the bottom fell out of the market.” As a result, the family found itself financially strapped for a year or so while Steve was in elementary school. His mother took a job as a bookkeeper for Varian Associates, a company that made scientific instruments, and they took out a second mortgage. One day his fourth-grade teacher asked him, “What is it you don’t understand about the universe?” Jobs replied, “I don’t understand why all of a sudden my dad is so broke.” He was proud that his father never adopted a servile attitude or slick style that may have made him a better salesman. “You had to suck up to people to sell real estate, and he wasn’t good at that and it wasn’t in his nature. I admired him for that.” Paul Jobs went back to being a mechanic. His father was calm and gentle, traits that his son later praised more than emulated. He was also resolute. Jobs described one exampl What made the neighborhood different from the thousands of other spindly-tree subpisions across America was that even the ne’er-do-wells tended to be engineers. “When we moved here, there were apricot and plum orchards on all of these corners,” Jobs recalled. “But it was beginning to boom because of military investment.” He soaked up the history of the valley and developed a yearning to play his own role. Edwin Land of Polaroid later told him about being asked by Eisenhower to help build the U-2 spy plane cameras to see how real the Soviet threat was. The film was dropped in canisters and returned to the NASA Ames Research Center in Sunnyvale, not far from where Jobs lived. “The first computer terminal I ever saw was when my dad brought me to the Ames Center,” he said. “I fell totally in love with it.” Other defense contractors sprouted nearby during the 1950s. The Lockheed Missiles and Space Division, which built submarine-launched ballistic missiles, was founded in 1956 next to the NASA Center; by the time Jobs moved to the area four years later, it employed twenty thousand people. A few hundred yards away, Westinghouse built facilities that produced tubes and electrical transformers for the missile systems. “You had all these military companies on the cutting edge,” he recalled. “It was mysterious and high-tech and made living here very exciting.” In the wake of the defense industries there arose a booming economy based on technology. Its roots stretched back to 1938, when David Packard and his new wife moved into a house in Palo Alto that had a shed where his friend Bill Hewlett was soon ensconced. The house had a garage—an appendage that would prove both useful and iconic in the valley—in which they tinkered around until they had their first product, an audio oscillator. By the 1950s, Hewlett-Packard was a fast-growing company making technical instruments. Fortunately there was a place nearby for entrepreneurs who had outgrown their garages. In a move that would help transform the area into the cradle of the tech revolution, Stanford University’s dean of engineering, Frederick Terman, created a seven-hundred-acre industrial park on university land for private companies that could commercialize the ideas of his students. Its first tenant was Varian Associates, where Clara Jobs worked. “Terman came up with this great idea that did more than anything to cause the tech industry to grow up here,” Jobs said. By the time Jobs was ten, HP had nine thousand employees and was the blue-chip company where every engineer seeking financial stability wanted to work. The most important technology for the region’s growth was, of course, the semiconductor. William Shockley, who had been one of the inventors of the transistor at Bell Labs in New Jersey, moved out to Mountain View and, in 1956, started a company to build transistors using silicon rather than the more expensive germanium that was then commonly used. But Shockley became increasingly erratic and abandoned his silicon transistor project, which led eight of his engineers—most notably Robert Noyce and Gordon Moore—to break away to form Fairchild Semiconductor. That company grew to twelve thousand employees, but it fragmented in 1968, when Noyce lost a power struggle to become CEO. He took Gordon Moore and founded a company that they called Integrated Electronics Corporation, which they soon smartly abbreviated to Intel. Their third employee was Andrew Grove, who later would grow the company by shifting its focus from memory chips to microprocessors. Within a few years there would be more than fifty companies in the area making semiconductors. The exponential growth of this industry was correlated with the phenomenon famously discovered by Moore, who in 1965 drew a graph of the speed of integrated circuits, based on the number of transistors that could be placed on a chip, and showed that it doubled about every two years, a trajectory that could be expected to continue. This was reaffirmed in 1971, when Intel was able to etch a complete central processing unit onto one chip, the Intel 4004, tronic amplifier. “So I raced home, and I told my dad that he was wrong.” “No, it needs an amplifier,” his father assured him. When Steve protested otherwise, his father said he was crazy. “It can’t work without an amplifier. There’s some trick.” “I kept saying no to my dad, telling him he had to see it, and finally he actually walked down with me and saw it. And he said, ‘Well I’ll be a bat out of hell.’” Jobs recalled the incident vividly because it was his first realization that his father did not know everything. Then a more disconcerting discovery began to dawn on him: He was smarter than his parents. He had always admired his father’s competence and savvy. “He was not an educated man, but I had always thought he was pretty damn smart. He didn’t read much, but he could do a lot. Almost everything mechanical, he could figure it out.” Yet the carbon microphone incident, Jobs said, began a jarring process of realizing that he was in fact more clever and quick than his parents. “It was a very big moment that’s burned into my mind. When I realized that I was smarter than my parents, I felt tremendous shame for having thought that. I will never forget that moment.” This discovery, he later told friends, along with the fact that he was adopted, made him feel apart—detached and separate—from both his family and the world. Another layer of awareness occurred soon after. Not only did he discover that he was brighter than his parents, but he discovered that they knew this. Paul and Clara Jobs were loving parents, and they were willing to adapt their lives to suit a son who was very smart—and also willful. They would go to great lengths to accommodate him. And soon Steve discovered this fact as well. “Both my parents got me. They felt a lot of responsibility once they sensed that I was special. They found ways to keep feeding me stuff and putting me in better schools. They were willing to defer to my needs.” So he grew up not only with a sense of having once been abandoned, but also with a sense that he was special. In his own mind, that was more important in the formation of his personality. School Even before Jobs started elementary school, his mother had taught him how to read. This, however, led to some problems once he got to school. “I was kind of bored for the first few years 在这种情况下，俄罗斯和欧洲正兴建一条新的天然气运输管道，这就是北溪-2项目，这个项目全长1224公里，从俄罗斯穿过波罗的海，将天然气运输到德国和其它国家，欧洲很多国家都参与了这条管道项目的建设，毕竟这是欧洲国家的民生工程。一旦这条管道建设完成，可以为欧洲提供每年330亿立方米的天然气，可以满足欧洲对天然气十分之一的需求，这可是非常大的。它是气态行星没有实体表面，由90%的氢和10%的氦（原子数之比, 75/25%的质量比）及微量的甲烷、水、氨水和“石头”组成。这与形成整个太阳系的原始的太阳系星云的组成十分相似。木星可能有一个石质的内核，相当于10－15个地球的质量。内核上则是大部分的行星物质集结地，以液态氢的形式存在。液态金属氢由离子化的质子与电子组成（类似于太阳的内部，不过温度低多了）。木星共有67颗木卫。按距离木星中心由近及远的次序为：木卫十六、木卫十四、木卫五、木卫十五、木卫一、木卫二、木卫三、木卫四、木卫十三、木卫六、木卫十、木卫七、木卫十二、木卫十一、木卫八和木卫九。[46] 水星是最接近太阳的行星。水星的半径约为2440公里，在八大行星中是最小的。水星昼夜温差极大，白天摄氏 430 度，晚上约可达零下170 度，是太阳系八大行星中温差最大的一个行星。[47]  水星的外大气层非常稀薄，是由水星表面和太阳风中的原子和离子构成。[48]  科学家确认水星表面含有丰富的碳，认为碳是水星表面呈黑色的原因，水星表面的岩石是由低重量百分比的石墨碳构成。[49] “好奇号”火星探测器在火星表面采集样本 “好奇号”火星探测器在火星表面采集样本 [50] 火星是地球的近邻，是太阳系由内往外数第四颗行星。直径6794km，体积为地球的15%，质量为地球的11%。火星表面是一个荒凉的世界，空气中二氧化碳占了95%。火星大气十分稀薄，密度还不到地球大气的1%，因而根本无法保存热量。这导致火星表面温度极低，很少超过0℃，在夜晚，最低温度则可达到-123℃。火星被称为红色的行星，这是因为它表面布满了氧化物，因而呈现出铁锈红色。其表面的大部分地区都是含有大量的红色氧化物的大沙漠，还有赭色的砾石地和凝固的熔岩流。火星上常常有猛烈的大风，大风扬起沙尘能形成可以覆盖火星全球的特大型沙尘暴。每次沙尘暴可持续数个星期。火星两极的冰冠和火星大气中含有水份。从火星表面获得的探测数据证明，在远古时期八颗行星，直径49532千米。海王星绕太阳运转的轨道半径为45亿千米，公转一周需要165年。海王星的直径和天王星类似，质量比天王星略大一些。海王星和天王星的主要大气成分都是氢和氦，内部结构也极为相近，所以说海王星与天王星是一对孪生兄弟。[55]  海王星有太阳系最强烈的风，测量到的时速高达2100公里。海王星云顶的温度是－218 °C，是太阳系最冷的地区之一。海王星核心的温度约为7000 °C，可以和太阳的表面比较。海王星在1846年9月23日被发现，是唯一利用数学预测而非有计划的观测发现的行星。[56] 冥王星，位于海王星以外的柯伊伯带内侧，是柯伊伯带中已知的最大天体。[57]  直径约为2370±20km，是地球直径的18.5%。[58] 2006年8月24日，国际天文学联合会大会24日投票决定，不再将传统九大行星之一的冥王星视为行星，而将其列入“矮行星”。大会通过的决议规定，“行星”指的是围绕太阳运转、自身引力足以克服其刚体力而使天体呈圆球状、能够清除其轨道附近其他物体的天体。在太阳系传统的“九大行星”中，只有水星、金星、地球、火星、木星、土星、天王星和海王星符合这些要求。冥王星由于其轨道与海王星的轨道相交，不符合新的行星定义，因此被自动降级为“矮行星”。[59]  冥王星的表面温度大概在-238到-228℃之间。冥王星的成份由70%岩石和30%冰水混合而成的。地表上光亮的部分可能覆盖着一些固体氮以及少量 卫星拍月球经过地球，可见清晰月球背面 卫星拍月球经过地球，可见清晰月球背面 [60] 的固体甲烷和一氧化碳，冥王星表面的黑暗部分可能是一些基本的有机物质或是由宇宙射线引发的光化学反应。冥王星的大气层主要由氮和少量的一氧化碳及甲烷组成。大气极其稀薄，地面压强只有少量微帕。[61] 地球是离太阳第三颗行星，是我们人类的家乡，尽管地球是太阳系中一颗普通的行星，但它在许多方面都是独一无二的。比如，它是太阳系中唯一一颗面积大部分被水覆盖的行星，也是目前所知唯一一颗有生命存在的星球。质量M=5.9742 ×10^24 公斤，表面温度：t = - 30 ～ +45。[62]  英国科研人员在《天体生物学》杂志上报告说，如果没有小行星撞击等可能剧烈改变环境的事件发生，地球适宜人类居住的时间还剩约17.5亿年，不过人为造成的气候变化可能缩短这一时间。[63] 彗星是由灰尘和冰块组成的太阳系中的一类小天体，绕日运动。[64]  科学家使用探测器对彗星的化学遗留物进行分析，发现其主要成份为氨、甲烷、硫化氢、氰化氢和甲醛。科学家得出结论称，彗星的气味闻起来像是臭鸡蛋、马尿、酒精和苦杏仁的气味综合。[65-66] “67P/楚留莫夫-格拉希门克”彗星 “67P/楚留莫夫-格拉希门克”彗星 [67] 在太阳系的周围还包裹着一个庞大的“奥尔特云”。星云内分布着不计其数的冰块、雪团和碎石。其中的某些会受太阳引力影响飞入内太阳系，这学说，在原有的轨道（或称小天体轨道）上又增加了更多的天体运行轨道。这一模式称每颗行星都沿着一个小轨道作圆周运行，而小轨道又沿着该行星的大轨道绕地球作圆周运动。几百年之后，这一模式的漏洞越来越明显。科学家们又在这个模式上增加了许多轨道，行星就这样沿着一道又一道的轨道作圆周运动。哥白尼想用“现代”（16世纪的）技术来改进托勒密的测量结果，以期取消一些小轨道。在长达近20年的时间里，哥白尼不辞辛劳日夜测量行星的位置，但其测量获得的结果仍然与托勒密的天体运行模式没有多少差别。哥白尼想知道在另一个运行着的行星上观察这些行星的运行情况会是什么样的。基于这种设想，哥白尼萌发了一个念头：假如地球在运行中，那么这些行星的运行看上去会是什么情况呢？这一设想在他脑海里变得清晰起来了。一年里，哥白尼在不同的时间、不同的距离从地球上观察行星，每一个行星的情况都不相同，这是他意识到地球不可能位于星星轨道的中心。经过20年的观测，哥白尼发现唯独太阳的周年变化不明显。这意味着地球和太阳的距离始终没有改变。如果地球不是宇宙的中心，那么宇宙的中心就是太阳。的发现才使牛顿有能力确定运动定律和万有引力定律。哥白尼的日心宇宙体系既然是时代的产物，它就不能不受到时代的限制。反对神学的不彻底性，同时表现在哥白尼的某些观点上，他的体系是存在缺陷的。哥白尼所指的宇宙是局限在一个小的范围内的，具体来说，他的宇宙结构就是今天我们所熟知的太阳系，即以太阳为中心的天体系统。宇宙既然有它的中心，就必须有它的边界，哥白尼虽然否定了托勒玫的“九重天”，但他却保留了一层恒星天，尽管他回避了宇宙是否有限这个问题，但实际上他是相信恒星天球是宇宙的“外壳”，他仍然相信天体只能按照所谓完美的圆形轨道运动，所以哥白尼的宇宙体系，仍然包含着不动的中心天体。但是作为近代自然科学的奠基人，哥白尼的历史功绩是伟大的。确认地球不是宇宙的中心，而是行星之一，从而掀起了一场天文学上根本性的革命，是人类探求客观真理道路上的里程碑。哥白尼的伟大成就，不仅铺平了通向近代天文学的道路，而且开创了整个自然界科学向前迈进的新时代。从哥白尼时代起，脱离教会束缚的自然科学和哲学开始获得飞跃的发展。哥白尼的科学成就，是他所处时代的产物，又转过来推动了时代的发展。顺应时代变化 十五、六世纪的欧洲，正是从封建社会向资本主义社会转变的关键时期，在这一二百年间，社会发生了巨大的变化。14世纪以前的欧洲，到处是四分五裂的小城邦。后来，随着城市工商业的兴起，特别是采矿和冶金业的发展，涌现了许多新兴的大城市，小城邦有了联合起来组成国家的趋势。到 15世纪末叶，在许多国家里都出现了基本上是中央集权的君主政体。当时的波兰不仅有像克拉科夫、波兹南这样的大城市，也有许多手工业兴盛的城

相比于霍乱，瓜妹觉得它的另一个名字更有张力—— 虎烈拉 。

虎烈拉，是根据英文名 Cholera的音译，也非常好地表现出其发病之迅猛

中国人对于它的恐惧，大多来自一个世纪前的河南大疫，当时有超过18万人感染，超过4万人死亡……

甚至当时中国最大的城市上海，都连年中招，伤亡惨重。

痛苦是有记忆的，而记忆会传承。

当年疫情中的灾民

河南当年疫情的惨烈，史书多有记载：

民国十八年(1929年)延津县春，大风三昼夜不息，黄沙蔽日，地面落沙盈尺，白天屋内点灯，二麦颗粒无收。秋，霍乱流行，人多死亡。南召县秋，全县瘟疫流行，“家家有病人，村村添新坟”。

登封县霍乱流行。中岳庙内求神拜药者成群结队，致使中岳庙村40%的群众感染此症。临颖县夏，霍乱大流行，全县患病人数达17万多，死亡无法计算，人死后无人敢埋。

浙川县民国十八到二十一年，霍乱在埠口、李官桥、马蹬一带流行，出现“购药店前身先死，送葬未归又命亡”的惨象，死亡逾万人。

民国二十年(01931年)堰师县农历六月二十九日，大雨如注，约一昼夜，水灾后，霍乱流行，死者甚众。永城县夏、秋之交，永城霍乱流行。染病者生存极少，急性者就地倒毙，慢性者延至次日身亡。

鹿邑县夏，全县“霍乱症”蔓延，城乡死者甚众。仅8, 9, 10三个月，城内居民病死636人。光山县夏，霍乱大流行，群众称之为 “发人瘟”，发病之快，死人之多，前所未有。城乡棺木为之一空，不少用芦席裹埋，情景极为悲惨。

霍乱，最早发现于印度。

一开始，部分印度人突然出现没完没了的腹泻症状，吃什么药都治不好。

更可怕的是，病症会传染， 被传染的人会 出现惊人腹泻，严重脱水，并 引发四肢痉挛和剧痛。

1817年，恒河洪水泛滥，霍乱传播到曼谷、泰国和菲律宾等地，1821年传入中国东南沿海，肆虐整个亚洲地区……

这是有记载的世界第一次霍乱疫情。

到1923年的百余年间，6次霍乱大流行，造成的损失难以计算。

无知和霍乱同样可怕。

由于当时的人们不知霍乱的传播渠道，只能坐以待毙。

1854年，英国伦敦再一次出现了霍乱大暴发，富人们争先恐后逃离，穷人只能绝望祈祷。

终于，一位英国医生 约翰·斯诺 通过病例分析 发现， 所有死亡案例都发生在一个叫宽街的地方。

最终，“凶手”被锁定在宽街的一口公用水井。

其后，人们意识到：真正传播霍乱的介质是 水 。政府听取建议封了水井，发病人数大幅减少。

此后数十年间，40多名科学家“以身试毒”，

燃烧生命和健康，推动了对霍乱的研究。

20世纪60年代初，第7次霍乱大流行传入中国，我国加强了防疫专业队伍和监测系统的建设。国务院曾专门召开过会议，并于1981年下发文件，明确提出“标本兼治，治本为主”的防治霍乱的对策原则，各地采取有力措施，加强监测和防治工作。

21世纪以来，中国的霍乱疫情已非常少见。

2004年，中国研制的新型口服霍乱疫苗上市，大幅降低了成本和副作用，并成为世卫组织推荐用药，已经在非洲等贫困地区推广。

近年来，非洲各地爆发的一连串霍乱疫情促使当地开展了历史上最大规模的霍乱疫苗接种运动，非洲大陆共有200多万人接受了口服霍乱疫苗。

目前，口服补液、静脉输液和抗生素的治疗体系已经能有效医治霍乱病患，死亡率可控制在1%以下。

史上最恐怖传染病的魅影，渐渐隐去，

但人类为此所做的努力，不该被遗忘。

They had arrived in San Francisco, where their ship was decommissioned, and Paul bet that he would find himself a wife within two weeks. He was a taut, tattooed engine mechanic, six feet tall, with a passing resemblance to James Dean. But it wasn’t his looks that got him a date with Clara Hagopian, a sweet-humored daughter of Armenian immigrants. It was the fact that he and his friends had a car, unlike the group she had originally planned to go out with that evening. Ten days later, in March 1946, Paul got engaged to Clara and won his wager. It would turn out to be a happy marriage, one that lasted until death parted them more than forty years later. Paul Reinhold Jobs had been raised on a dairy farm in Germantown, Wisconsin. Even though his father was an alcoholic and sometimes abusive, Paul ended up with a gentle and calm disposition under his leathery exterior. After dropping out of high mechanic until, at age nineteen, he joined the Coast Guard, even though he didn’t know how to swim. He was deployed on the USS General M. C. Meigs and spent much of the war ferrying troops to Italy for General Patton. His talent as a machinist and fireman earned him commendations, but he occasionally found himself in minor trouble and never rose above the rank of seaman. Clara was born in New Jersey, where her parents had landed after fleeing the Turks in Armenia, and they moved to the Mission District of San Francisco when she was a child. She had a secret that she rarely mentioned to anyone: She had been married before, but her husband had been killed in the war. So when she met Paul Jobs on that first date, she was primed to start a new life. Clara, however, loved San Francisco, and in 1952 she convinced her husband to move back there. They got an apartment in the Sunset District facing the Pacific, just south of Golden Gate Park, and he took a job working for a finance company as a “repo man,” picking the locks of cars whose owners hadn’t paid their loans and repossessing them. He also bought, repaired, and sold some of the cars, making a decent enough living in the process. There was, however, something missing in their lives. They wanted children, but Clara had suffered an ectopic pregnancy, in which the fertilized egg was implanted in a fallopian tube rather than the uterus, and she had been unable to have any. So by 1955, after nine years of marriage, they were looking to adopt a child. Like Paul Jobs, Joanne Schieble was from a rural Wisconsin family of German heritage. Her father, Arthur Schieble, had immigrated to the outskirts of Green Bay, where he and his wife owned a mink farm and dabbled successfully in various other businesses, including real estate and photoengraving. He was very strict, especially regarding his daughter’s relationships, and he had strongly disapproved of her first love, an artist who was not a Catholic. Thus it was no surprise that he threatened to cut Joanne off completely when, as a graduate student at the University of Wisconsin, she fell in love with Abdulfattah “John” Jandali, a Muslim teaching assistant from Syria. Jandali was the youngest of nine children in a prominent Syrian family. His father owned oil refineries and multiple other businesses, with large holdings in Damascus and Homs, and at one point pretty much controlled the price of wheat in the region. His mother, he later said, was a “traditional Muslim woman” who was a “conservative, obedient housewife.” Like the Schieble family, the Jandalis put a premium on education. Abdulfattah was sent to a Jesuit boarding school, even though he was Muslim, and he got an undergraduate degree at the American University in Beirut before entering the University of Wisconsin to pursue a doctoral degree in political science. In the summer of 1954, Joanne went with Abdulfattah to Syria. They spent two months in Homs, where she learned from his family to cook Syrian dishes. When they returned to Wisconsin she discovered that she was pregnant. They were both twenty-three, but they decided not to get married. Her father was dying at the time, and he had threatened to disown her if she wed Abdulfattah. Nor was abortion an easy option in a small Catholic community. So in early 1955, Joanne traveled to San Francisco, where she was taken into the care of a kindly doctor who sheltered unwed mothers, delivered their babies, and quietly arranged closed adoptions. Joanne had one requirement: Her child must be adopted by college graduates. So the doctor arranged for the baby to be placed with a lawyer and his wife. But when a boy was born—on February 24, 1955—the designated couple decided that they wanted a girl and backed out. Thus it was that the boy became the son not of a lawyer but of a high school dropout with a passion for mechanics and his salt-of-the-earth wife who was working as a bookkeeper. Paul and Clara named their new baby Steven Paul Jobs. When Joanne found out that her baby had been placed with a couple who had not even graduated from high school, she refused to sign the adoption papers. The standoff lasted weeks, even after the baby had settled into the Jobs household. Eventually Joanne relented, with the stipulation that the couple promise—indeed sign a pledge—to fund a savings account to pay for the boy’s college education. There was another reason that Joanne was balky about signing the adoption papers. Her father was about to die, and she planned to marry Jandali soon after. She held out hope, she would later tell family members, sometimes tearing up at the memory, that once they were married, she could get their 别让梦想只停留在梦里。181.

Arthur Schieble died in August 1955, after the adoption was finalized. Just after Christmas that year, Joanne and Abdulfattah were married in St. Philip the Apostle Catholic Church in Green Bay. He got his PhD in international politics the next year, and then they had another child, a girl named Mona. After she and Jandali porced in 1962, Joanne embarked on a dreamy and peripatetic life that her daughter, who grew up to become the acclaimed novelist Mona Simpson, would capture in her book Anywhere but Here. Because Steve’s adoption had been closed, it would be twenty years before they would all find each other. Steve Jobs knew from an early age that he was adopted. “My parents were very open with me about that,” he recalled. He had a vivid memory of sitting on the lawn of his house, when he was six or seven years old, telling the girl who lived across the street. “So does that mean your real parents didn’t want you?” the girl asked. “Lightning bolts went off in my head,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eye. They said, ‘We specifically picked you out.’ Both of my parents said that and repeated it slowly for me. And they put an emphasis on every word in that sentence.” Abandoned. Chosen. Special. Those concepts became part of who Jobs was and how he regarded himself. His closest friends think that the knowledge that he was given up at birth left some scars. “I think his desire for complete control of whatever he makes derives directly from his personality and the fact that he was abandoned at birth,” said one longtime colleague, Del Yocam. “He wants to control his environment, and he sees the product as an extension of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned and the pain that caused,” he said. “It made him independent. He followed the beat of a different drummer, and that came from being in a different world than he was born into.” Later in life, when he was the same age his biological father had been when he abandoned him, Jobs would father and abandon a child of his own. (He eventually took responsibility for her.) Chrisann Brennan, the mother of that child, said that being put up for adoption left Jobs “full of broken glass,” and it helps to explain some of his behavior. “He who is abandoned is an abandoner,” she said. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to both Brennan and Jobs. “The key question about Steve is why he can’t control himself at times from being so reflexively cruel and harmful to some people,” he said. “That goes back to being abandoned at birth. The real underlying problem was the theme of abandonment in Steve’s life.” Jobs dismissed this. “There’s some notion that because I was abandoned, I worked very hard so I could do well and make my parents wish they had me back, or some such nonsense, but that’s ridiculous,” he insisted. “Knowing I was adopted may have made me feel more independent, but I have never felt abandoned. I’ve always felt special. My parents made me feel special.” He would later bristle whenever anyone referred to Paul and Clara Jobs as his “adoptive” parents or implied that they were not his “real” parents. “They were my parents 1,000%,” he said. When speaking about his biological parents, on the other hand, he was curt: “They were my sperm and egg bank. That’s not harsh, it’s just the way it was, a sperm bank thing, nothing more.” Silicon Valley The childhood that Paul and Clara Jobs created for their new son was, in many ways, a stereotype of the late 1950s. When Steve was two they adopted a girl they named Patty, and three years later they moved to a tract house in the suburbs. The finance company where Paul worked as a repo man, CIT, had transferred him down to its Palo Alto office, but he could not afford to live there, so they landed in a subpision in Mountain View, a less expensive town just to the south. There Paul tried to pass along his love of mechanics and cars. “Steve, this is your workbench now,” he said as he marked off a section of the table in their garage. Jobs remembered being impressed by his father’s focus on craftsmanship. “I thought my dad’s sense of design was pretty good,” he said, “because he knew how to build anything. If we needed a cabinet, he would build it. When he built our fence, he gave me a hammer so I could work with him.” Fifty years later the fence still surrounds the back and side yards of the house in Mountain View. As Jobs showed it off to me, he caressed the stockade panels and recalled a lesson that his father implanted deeply in him. It was important, his father said, to craft the backs of cabinets and fences properly, even though they were hidden. “He loved doing things right. He even cared about the look of the parts you couldn’t see.” His father continued to refurbish and resell used cars, and he festooned the garage with pictures of his favorites. He would point out the detailing of the design to his son: the lines, the vents, the chrome, the trim of the seats. After work each day, he would change into his dungarees and retreat to the garage, often with Steve tagging along. “I figured I could get him nailed down with a little mechanical ability, but he really wasn’t interested in getting his hands dirty,” Paul later recalled. “He never really cared too much about m189.

One day when he was about eight, he discovered a photograph of his father from his time in the Coast Guard. “He’s in the engine room, and he’s got his shirt off and looks like James Dean. It was one of those Oh wow moments for a kid. Wow, oooh, my parents were actually once very young and really good-looking.” Through cars, his father gave Steve his first exposure to electronics. “My dad did not have a deep understanding of electronics, but he’d encountered it a lot in automobiles and other things he would fix. He showed me the rudiments of electronics, and I got very interested in that.” Even more interesting were the trips to scavenge for parts. “Every weekend, there’d be a junkyard trip. We’d be looking for a generator, a carburetor, all sorts of components.” He remembered watching his father negotiate at the counter. “He was a good bargainer, because he knew better than the guys at the counter what the parts should cost.” This helped fulfill the pledge his parents made when he was adopted. “My college fund came from my dad paying $50 for a Ford Falcon or some other beat-up car that didn’t run, working on it for a few weeks, and selling it for $250—and not telling the IRS.” The Jobses’ house and the others in their neighborhood were built by the real estate developer Joseph Eichler, whose company spawned more than eleven thousand homes in various California subpisions between 1950 and 1974. Inspired by Frank Lloyd Wright’s vision of simple modern homes for the American “everyman,” Eichler built inexpensive houses that featured floor-to-ceiling glass walls, open floor plans, exposed post-and-beam construction, concrete slab floors, and lots of sliding glass doors. “Eichler did a great thing,” Jobs said on one of our walks around the neighborhood. “His houses were smart and cheap and good. They brought clean design and simple taste to lower-income people. They had awesome little features, like radiant heating in the floors. You put carpet on them, and we had nice toasty floors when we were kids.” Jobs said that his appreciation for Eichler homes instilled in him a passion for making nicely designed products for the mass market. “I love it when you can bring really great design and simple capability to something that doesn’t cost much,” he said as he pointed out the clean elegance of the houses. “It was the original vision for Apple. That’s what we tried to do with the first Mac. That’s what we did with the iPod.” Across the street from the Jobs family lived a man who had become successful as a real estate agent. “He wasn’t that bright,” Jobs recalled, “but he seemed to be making a fortune. So my dad thought, ‘I can do that.’ He worked so hard, I remember. He took these night classes, passed the license test, and got into real estate. Then the bottom fell out of the market.” As a result, the family found itself financially strapped for a year or so while Steve was in elementary school. His mother took a job as a bookkeeper for Varian Associates, a company that made scientific instruments, and they took out a second mortgage. One day his fourth-grade teacher asked him, “What is it you don’t understand about the universe?” Jobs replied, “I don’t understand why all of a sudden my dad is so broke.” He was proud that his father never adopted a servile attitude or slick style that may have made him a better salesman. “You had to suck up to people to sell real estate, and he wasn’t good at that and it wasn’t in his nature. I admired him for that.” Paul Jobs went back to being a mechanic. His father was calm and gentle, traits that his son later praised more than emulated. He was also resolute. Jobs described one exampl What made the neighborhood different from the thousands of other spindly-tree subpisions across America was that even the ne’er-do-wells tended to be engineers. “When we moved here, there were apricot and plum orchards on all of these corners,” Jobs recalled. “But it was beginning to boom because of military investment.” He soaked up the history of the valley and developed a yearning to play his own role. Edwin Land of Polaroid later told him about being asked by Eisenhower to help build the U-2 spy plane cameras to see how real the Soviet threat was. The film was dropped in canisters and returned to the NASA Ames Research Center in Sunnyvale, not far from where Jobs lived. “The first computer terminal I ever saw was when my dad brought me to the Ames Center,” he said. “I fell totally in love with it.” Other defense contractors sprouted nearby during the 1950s. The Lockheed Missiles and Space Division, which built submarine-launched ballistic missiles, was founded in 1956 next to the NASA Center; by the time Jobs moved to the area four years later, it employed twenty thousand people. A few hundred yards away, Westinghouse built facilities that produced tubes and electrical transformers for the missile systems. “You had all these military companies on the cutting edge,” he recalled. “It was mysterious and high-tech and made living here very exciting.” In the wake of the defense industries there arose a booming economy based on technology. Its roots stretched back to 1938, when David Packard and his new wife moved into a house in Palo Alto that had a shed where his friend Bill Hewlett was soon ensconced. The house had a garage—an appendage that would prove both useful and iconic in the valley—in which they tinkered around until they had their first product, an audio oscillator. By the 1950s, Hewlett-Packard was a fast-growing company making technical instruments. Fortunately there was a place nearby for entrepreneurs who had outgrown their garages. In a move that would help transform the area into the cradle of the tech revolution, Stanford University’s dean of engineering, Frederick Terman, created a seven-hundred-acre industrial park on university land for private companies that could commercialize the ideas of his students. Its first tenant was Varian Associates, where Clara Jobs worked. “Terman came up with this great idea that did more than anything to cause the tech industry to grow up here,” Jobs said. By the time Jobs was ten, HP had nine thousand employees and was the blue-chip company where every engineer seeking financial stability wanted to work. The most important technology for the region’s growth was, of course, the semiconductor. William Shockley, who had been one of the inventors of the transistor at Bell Labs in New Jersey, moved out to Mountain View and, in 1956, started a company to build transistors using silicon rather than the more expensive germanium that was then commonly used. But Shockley became increasingly erratic and abandoned his silicon transistor project, which led eight of his engineers—most notably Robert Noyce and Gordon Moore—to break away to form Fairchild Semiconductor. That company grew to twelve thousand employees, but it fragmented in 1968, when Noyce lost a power struggle to become CEO. He took Gordon Moore and founded a company that they called Integrated Electronics Corporation, which they soon smartly abbreviated to Intel. Their third employee was Andrew Grove, who later would grow the company by shifting its focus from memory chips to microprocessors. Within a few years there would be more than fifty companies in the area making semiconductors. The exponential growth of this industry was correlated with the phenomenon famously discovered by Moore, who in 1965 drew a graph of the speed of integrated circuits, based on the number of transistors that could be placed on a chip, and showed that it doubled about every two years, a trajectory that could be expected to continue. This was reaffirmed in 1971, when Intel was able to etch a complete central processing unit onto one chip, the Intel 4004, tronic amplifier. “So I raced home, and I told my dad that he was wrong.” “No, it needs an amplifier,” his father assured him. When Steve protested otherwise, his father said he was crazy. “It can’t work without an amplifier. There’s some trick.” “I kept saying no to my dad, telling him he had to see it, and finally he actually walked down with me and saw it. And he said, ‘Well I’ll be a bat out of hell.’” Jobs recalled the incident vividly because it was his first realization that his father did not know everything. Then a more disconcerting discovery began to dawn on him: He was smarter than his parents. He had always admired his father’s competence and savvy. “He was not an educated man, but I had always thought he was pretty damn smart. He didn’t read much, but he could do a lot. Almost everything mechanical, he could figure it out.” Yet the carbon microphone incident, Jobs said, began a jarring process of realizing that he was in fact more clever and quick than his parents. “It was a very big moment that’s burned into my mind. When I realized that I was smarter than my parents, I felt tremendous shame for having thought that. I will never forget that moment.” This discovery, he later told friends, along with the fact that he was adopted, made him feel apart—detached and separate—from both his family and the world. Another layer of awareness occurred soon after. Not only did he discover that he was brighter than his parents, but he discovered that they knew this. Paul and Clara Jobs were loving parents, and they were willing to adapt their lives to suit a son who was very smart—and also willful. They would go to great lengths to accommodate him. And soon Steve discovered this fact as well. “Both my parents got me. They felt a lot of responsibility once they sensed that I was special. They found ways to keep feeding me stuff and putting me in better schools. They were willing to defer to my needs.” So he grew up not only with a sense of having once been abandoned, but also with a sense that he was special. In his own mind, that was more important in the formation of his personality. School Even before Jobs started elementary school, his mother had taught him how to read. This, however, led to some problems once he got to school. “I was kind of bored for the first few years 在这种情况下，俄罗斯和欧洲正兴建一条新的天然气运输管道，这就是北溪-2项目，这个项目全长1224公里，从俄罗斯穿过波罗的海，将天然气运输到德国和其它国家，欧洲很多国家都参与了这条管道项目的建设，毕竟这是欧洲国家的民生工程。一旦这条管道建设完成，可以为欧洲提供每年330亿立方米的天然气，可以满足欧洲对天然气十分之一的需求，这可是非常大的。它是气态行星没有实体表面，由90%的氢和10%的氦（原子数之比, 75/25%的质量比）及微量的甲烷、水、氨水和“石头”组成。这与形成整个太阳系的原始的太阳系星云的组成十分相似。木星可能有一个石质的内核，相当于10－15个地球的质量。内核上则是大部分的行星物质集结地，以液态氢的形式存在。液态金属氢由离子化的质子与电子组成（类似于太阳的内部，不过温度低多了）。木星共有67颗木卫。按距离木星中心由近及远的次序为：木卫十六、木卫十四、木卫五、木卫十五、木卫一、木卫二、木卫三、木卫四、木卫十三、木卫六、木卫十、木卫七、木卫十二、木卫十一、木卫八和木卫九。[46] 水星是最接近太阳的行星。水星的半径约为2440公里，在八大行星中是最小的。水星昼夜温差极大，白天摄氏 430 度，晚上约可达零下170 度，是太阳系八大行星中温差最大的一个行星。[47]  水星的外大气层非常稀薄，是由水星表面和太阳风中的原子和离子构成。[48]  科学家确认水星表面含有丰富的碳，认为碳是水星表面呈黑色的原因，水星表面的岩石是由低重量百分比的石墨碳构成。[49] “好奇号”火星探测器在火星表面采集样本 “好奇号”火星探测器在火星表面采集样本 [50] 火星是地球的近邻，是太阳系由内往外数第四颗行星。直径6794km，体积为地球的15%，质量为地球的11%。火星表面是一个荒凉的世界，空气中二氧化碳占了95%。火星大气十分稀薄，密度还不到地球大气的1%，因而根本无法保存热量。这导致火星表面温度极低，很少超过0℃，在夜晚，最低温度则可达到-123℃。火星被称为红色的行星，这是因为它表面布满了氧化物，因而呈现出铁锈红色。其表面的大部分地区都是含有大量的红色氧化物的大沙漠，还有赭色的砾石地和凝固的熔岩流。火星上常常有猛烈的大风，大风扬起沙尘能形成可以覆盖火星全球的特大型沙尘暴。每次沙尘暴可持续数个星期。火星两极的冰冠和火星大气中含有水份。从火星表面获得的探测数据证明，在远古时期八颗行星，直径49532千米。海王星绕太阳运转的轨道半径为45亿千米，公转一周需要165年。海王星的直径和天王星类似，质量比天王星略大一些。海王星和天王星的主要大气成分都是氢和氦，内部结构也极为相近，所以说海王星与天王星是一对孪生兄弟。[55]  海王星有太阳系最强烈的风，测量到的时速高达2100公里。海王星云顶的温度是－218 °C，是太阳系最冷的地区之一。海王星核心的温度约为7000 °C，可以和太阳的表面比较。海王星在1846年9月23日被发现，是唯一利用数学预测而非有计划的观测发现的行星。[56] 冥王星，位于海王星以外的柯伊伯带内侧，是柯伊伯带中已知的最大天体。[57]  直径约为2370±20km，是地球直径的18.5%。[58] 2006年8月24日，国际天文学联合会大会24日投票决定，不再将传统九大行星之一的冥王星视为行星，而将其列入“矮行星”。大会通过的决议规定，“行星”指的是围绕太阳运转、自身引力足以克服其刚体力而使天体呈圆球状、能够清除其轨道附近其他物体的天体。在太阳系传统的“九大行星”中，只有水星、金星、地球、火星、木星、土星、天王星和海王星符合这些要求。冥王星由于其轨道与海王星的轨道相交，不符合新的行星定义，因此被自动降级为“矮行星”。[59]  冥王星的表面温度大概在-238到-228℃之间。冥王星的成份由70%岩石和30%冰水混合而成的。地表上光亮的部分可能覆盖着一些固体氮以及少量 卫星拍月球经过地球，可见清晰月球背面 卫星拍月球经过地球，可见清晰月球背面 [60] 的固体甲烷和一氧化碳，冥王星表面的黑暗部分可能是一些基本的有机物质或是由宇宙射线引发的光化学反应。冥王星的大气层主要由氮和少量的一氧化碳及甲烷组成。大气极其稀薄，地面压强只有少量微帕。[61] 地球是离太阳第三颗行星，是我们人类的家乡，尽管地球是太阳系中一颗普通的行星，但它在许多方面都是独一无二的。比如，它是太阳系中唯一一颗面积大部分被水覆盖的行星，也是目前所知唯一一颗有生命存在的星球。质量M=5.9742 ×10^24 公斤，表面温度：t = - 30 ～ +45。[62]  英国科研人员在《天体生物学》杂志上报告说，如果没有小行星撞击等可能剧烈改变环境的事件发生，地球适宜人类居住的时间还剩约17.5亿年，不过人为造成的气候变化可能缩短这一时间。[63] 彗星是由灰尘和冰块组成的太阳系中的一类小天体，绕日运动。[64]  科学家使用探测器对彗星的化学遗留物进行分析，发现其主要成份为氨、甲烷、硫化氢、氰化氢和甲醛。科学家得出结论称，彗星的气味闻起来像是臭鸡蛋、马尿、酒精和苦杏仁的气味综合。[65-66] “67P/楚留莫夫-格拉希门克”彗星 “67P/楚留莫夫-格拉希门克”彗星 [67] 在太阳系的周围还包裹着一个庞大的“奥尔特云”。星云内分布着不计其数的冰块、雪团和碎石。其中的某些会受太阳引力影响飞入内太阳系，这学说，在原有的轨道（或称小天体轨道）上又增加了更多的天体运行轨道。这一模式称每颗行星都沿着一个小轨道作圆周运行，而小轨道又沿着该行星的大轨道绕地球作圆周运动。几百年之后，这一模式的漏洞越来越明显。科学家们又在这个模式上增加了许多轨道，行星就这样沿着一道又一道的轨道作圆周运动。哥白尼想用“现代”（16世纪的）技术来改进托勒密的测量结果，以期取消一些小轨道。在长达近20年的时间里，哥白尼不辞辛劳日夜测量行星的位置，但其测量获得的结果仍然与托勒密的天体运行模式没有多少差别。哥白尼想知道在另一个运行着的行星上观察这些行星的运行情况会是什么样的。基于这种设想，哥白尼萌发了一个念头：假如地球在运行中，那么这些行星的运行看上去会是什么情况呢？这一设想在他脑海里变得清晰起来了。一年里，哥白尼在不同的时间、不同的距离从地球上观察行星，每一个行星的情况都不相同，这是他意识到地球不可能位于星星轨道的中心。经过20年的观测，哥白尼发现唯独太阳的周年变化不明显。这意味着地球和太阳的距离始终没有改变。如果地球不是宇宙的中心，那么宇宙的中心就是太阳。的发现才使牛顿有能力确定运动定律和万有引力定律。哥白尼的日心宇宙体系既然是时代的产物，它就不能不受到时代的限制。反对神学的不彻底性，同时表现在哥白尼的某些观点上，他的体系是存在缺陷的。哥白尼所指的宇宙是局限在一个小的范围内的，具体来说，他的宇宙结构就是今天我们所熟知的太阳系，即以太阳为中心的天体系统。宇宙既然有它的中心，就必须有它的边界，哥白尼虽然否定了托勒玫的“九重天”，但他却保留了一层恒星天，尽管他回避了宇宙是否有限这个问题，但实际上他是相信恒星天球是宇宙的“外壳”，他仍然相信天体只能按照所谓完美的圆形轨道运动，所以哥白尼的宇宙体系，仍然包含着不动的中心天体。但是作为近代自然科学的奠基人，哥白尼的历史功绩是伟大的。确认地球不是宇宙的中心，而是行星之一，从而掀起了一场天文学上根本性的革命，是人类探求客观真理道路上的里程碑。哥白尼的伟大成就，不仅铺平了通向近代天文学的道路，而且开创了整个自然界科学向前迈进的新时代。从哥白尼时代起，脱离教会束缚的自然科学和哲学开始获得飞跃的发展。哥白尼的科学成就，是他所处时代的产物，又转过来推动了时代的发展。顺应时代变化 十五、六世纪的欧洲，正是从封建社会向资本主义社会转变的关键时期，在这一二百年间，社会发生了巨大的变化。14世纪以前的欧洲，到处是四分五裂的小城邦。后来，随着城市工商业的兴起，特别是采矿和冶金业的发展，涌现了许多新兴的大城市，小城邦有了联合起来组成国家的趋势。到 15世纪末叶，在许多国家里都出现了基本上是中央集权的君主政体。当时的波兰不仅有像克拉科夫、波兹南这样的大城市，也有许多手工业兴盛的城
