The theory of evolution is one of the great intellectual revolutions of human history.

  When Darwin published his famous On the Origin of Species by Means of Natural Selection, members of the religious community, as well as some scientific peers, were outraged and protested. However, Darwin's idea was eventually accepted and had drastically changed our perception of the world and of our place in it.(原文)

  Hundreds of years ago, people were confused with the complexity of different species of the world, and believed that species were created by the mysterious God. However, Darwin did not believe so. After several years' study, he eventually demonstrated that species, however complex seemingly, all evolved by natural selection from simple and preliminary conditions. Darwin's theory revealed the simple principle of the world, and thus became a revolution of human beings.(复杂理论的简单性)

  For example, when Darwin published his famous research results "Origin of Species", the book encountered lots of controversies. On the one hand, the members of the religious community, as well as some scientific peers, stubbornly held their belief that each organism and each adaptation was the work of the creator, and were outraged about Darwin’s ideas. On the other hand, some insightful scientists tended to acknowledge Darwin' researches. Eventually the theory of evolution defeated the traditional belief, and now is reverenced as one of the greatest intellectual revolutions of human history.(个人不被时代承认)


  After the planet Uranus had been discovered, a Cambridge mathematician, Adams, predicted the existence of an unseen planet, to account for the fact that Uranus was being pulled slightly out of position in its orbit. According to Isaac Newton's theory of gravitation, Adams attributed this pull to the gravitational effect of an unknown body, and calculated its position. One year later (September 1846), this new planet, Neptune, was discovered, and its position was quite in accordance with the prediction.

  From the fact that planet Uranus was a bit pulled out of its normal orbit, some mathematicians logically reasoned the existence of a new planet, Neptune, and even precisely calculated its position according to Newton's theory of universal gravitation in 1845. One year later Neptune was discovered just around the predicted position.



  With the help of the Hubble space telescope, we can get more close to the universe and observe the stars, planets, nebulas, galaxies much more conveniently.


  A researcher working for 3M, a materials company, had planned to make the world greatest glue. However, in the research he found the world’s worst glue, a sticky substance that never sticks. This glue is one of the best things 3M ever invented.


  In an autocratic society, people are not only encouraged but actually coerced into suppressing individual personality; and indeed these people are afraid to think and behave differently—not for fear of being excluded but rather for fear of punishment and persecution by the state. The modern Communist and Fascist regimes are fitting examples. Every society has its own bundle of values, customs, and mores which most of its members share.

  One need look no further than the famous Einstein-Bohr Debate on determinacy - indeterminacy of quantum theories. On one hand, Einstein believed that quantum physics would eventually be replaced by a more determinate theory. Bohr, on the other hand, accepted the finality of the probability-based quantum theory. Their debate brought about chaos theory, which finally solved the debate by proposing wave-particle duality. When viewed from this perspective, the Einstein-Bohr debate evaporates. Depending on which part of the spiral we look, Bohr or Einstein will appear correct.
