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 divorced 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 subdivision 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 subdivisions 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 subdivisions 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

靴子，终于落地。
北京时间2021年8月25日，北京市正式召开了“教育‘双减’工作新闻发布会”。在会议上，北京正式披露了即将实行的“ 教师轮岗制度 ”的所有细节。1，这是全国所有城市里面，第一个站出来，公布教师轮岗制细节的重量级城市！意义超级重大。2，这次的文件内容，教师轮岗的力度超过所有人的预期，受影响的人群，太多太多。几乎所有看过了今天北京公布的这份文件的朋友，都被震撼到，学区房，这次算是彻底完了。。废话不多说，我给你们看看这次发布会关于教师轮岗的要点：所有距离退休时间超过5年的，且在同一所学校任职满6年的公办学校正、副校长，原则上都要进行交流轮岗；公办学校的在编在岗教师，凡距离退休时间超过5年的，且在同一所学校连续工作6年及以上的老师，原则上都要进行交流轮岗。3，北京东城区、密云区作为试点，第一个开始进行教师轮岗根据此次文件的公布，北京已正式选取东城区、密云区作为试点，率先开始干部教师轮岗交流工作。随后，全市一个一个逐步扩大试点，在今年年底之前，再启动六个区的干部教师轮岗交流试点。其中明确要求：东城干部教师今年不少于2000人立即执行交流轮岗，三年内东城所有教师，符合范围的，必须100%完成交流轮岗。
包括校长交流轮换、骨干教师均衡配置、普通教师派位轮岗，全都一一列出了。城区内：完善学区（教育集团）改革，着力推进跨学区（教育集团）交流轮岗。在推进学区（教育集团等）内校际间师资均衡配置基础上，重点推进全区范围内义务教育学校校长交流轮换，区级以上骨干教师均衡配置，普通教师派位轮岗。仔细注意，上面说的首先第一个要点就是师资均衡。也就是说以前那种有的学校，拨款多，可以大量招聘国际名校毕业的老师，这种现象以后将彻底没了。
不管是校长，还是骨干级别的教师（优秀教师），还是普通教师，都将进行彻底打乱，重新派位，彻底轮岗。
此举，对于北京城区范围内，以前的好学校，学区房，将是一个彻底的推翻。按照这个举措，短则2年，长则5年，基本上所有的学校，师资力量将会回到同一起跑线，再也没有什么“ 名校 ”，“ 普通学校 ”之分了。。这次的轮岗教师细节的公布，力度真的太大太大！！那些以前花了20万一平，10万一平，买了天价学区房的，百分百要彻底砸在手里了。。郊区也一样，全面推进交流轮岗。在全区范围内，推进所有符合条件的义务教育学校的校长进行交流轮换，所有符合条件的区级以上骨干教师，进行重新均衡配置，普通教师重新派位轮岗。也就是说从此次北京公布的教师轮岗细节来看，不管是北京城区内，还是郊区。力度都是超级超级大！
此举，等于彻底推翻了过去北京所有的小学，初中“ 名校 ”。这是一次非常彻底的学校，教师，大洗牌！！
将义务教育学校校长，教师，参与交流轮岗的工作绩效，作为日后评选的重要依据！包括校长职级晋升，教师专业技术职务评聘与晋升，区级及以上骨干教师评选、评优评先等等等奖励的评选。原文是，切实保障参加交流轮岗校长教师的工资待遇，在绩效工资分配中予以适当倾斜。可能很多人不知道，以前其实每个学校的教师，工资待遇还是有一些相差的。这句话的意思，我的理解是：如果一些原先收入待遇比较高的教师，分配到了比以前低一点收入的学校去轮岗，那在新的绩效工资分配时，会给予一定的倾斜，也就是“ 额外补贴 ”。。
毕竟按照目前的教育改革来看，以后教师的本职工作肯定更重了，如果收入不增反降，那肯定不合适。。没错，就是正式的那种“ 编制内教师岗位 ”，其中仅仅今年北京市就将从学科类校外培训机构员工中招聘366人，提供“ 编制内教师岗位 ”。毕竟以前很多很多培训机构，都是高价挖走的学校的优秀教师。现在学科内培训的几乎变成了公益。这些原先的优秀老师，自然得回到教书育人最开始的地方，也就是学校！！
这部分老师，本来以前就是“ 教书成绩非常优秀 ”，不然人家也不会开高薪来挖走她们。
现在将这些优秀的教师，重新给一个“ 正式岗位的机会 ”，肯定能吸引很多很多以前走出去的优秀老师，回来学校！这个举措，不管是对于学校，还是对于我们普通老百姓的孩子，学生，来说。都是一个好事情。。肯定举双手赞成。熟悉教育的朋友都知道，一所名校的产生需要三大因素——好校长、好老师、好学生。三者缺一不可！现在这三者完全被“ 教师轮岗制度 ”彻底打乱！打散了！
真的，教师轮岗制度，是目前为止，全球200多个国家，已经出现过的；制裁学区房，打压学区房，最狠最狠的招，没有之一。。时间回到20天前，当时中国改革开放的最前沿——深圳，第一个率先在中国扔出重磅炸弹。
成为中国第一个喊出，建立义务教育阶段“ 教师轮岗制度 ”的重量级城市！深圳第一时间在深圳政府官网上公开向所有深圳市民征求意见！打响了中国教育改革的第一枪。
深圳的教师轮换制度 ，虽然目前细节还没出来，但从当时的征求意见稿看的出一些影子：也是跟北京类似，简单来说，就是各个学校的教师们以后要流动起来，不能终身在一个学校教书，而是每隔几年，就必须换一个学校任教。不管你是普通的老师，还是优秀的老师，特级教师，哪怕是校长。都不能一直在一个学校教书。1，不管你家附近的学校，以前教育质量如何。哪怕是之前排名第一，第二的学校，也一样要进行“ 教师大洗牌 ”。包括校长，优秀老师，普通老师，全都要参与进来，重新分配！！也就是说好校长，好老师，都将被分走。2，也就是说以前的名校，里面的师资，包括好校长，好老师，原先的那一批人，现在都得走。。很明显，没有了好校长，好老师，那名校从此以后的“ 成绩”会如何？？很明显，名校以后的成绩必将一落千丈。这是必然的！！所以说，教师轮岗制度的实行，是一种真正，且直接将教育，彻底公平，彻底洗牌，直接均衡化的超级超级大招！！但是，对于那些奔着“ 名校 ”头衔，以前打着名校的光环，炒作学区房的人来说，这就是一个噩梦。。你们等着看吧。学区房，特别是那些价格比周边高出很多的天价学区房，百分百将开始迎来，雪崩式的暴跌！
今天，北京宣布的交流轮岗制度相关细节，真的太厉害太厉害，超出了很多很多人的预期。特别是这一条：只有距离退休不到5年的校长、老师才能避免轮换。也就是说在一个学校干满6年，就必须要进行交流轮岗。等于每个老师以后在一生中至少要轮换5到6个学校。并且，其中的骨干老师，也就是名师，优秀老师，将被重点盯上，直接一个一个被“ 均衡配置 ”，指派到一个又一个其他的学校，实现各大学校“ 优秀老师 ”彻底平均化！而，普通老师，则采用随机派位的方式。每个学校轮！！这是对于所有学校的一次真正的大洗牌。也是对所有符合年龄，条件的教师的重新大分配。
今天之后，北京再无“ 小学名校 ”，“ 初中名校 ”；
北京，深圳，已经率先动手！启动教师轮岗制度！！其他的城市还会远吗？？？过去持续，陪伴了我们几代人，几十年的传统教育，传统房产的模式；11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
