The 20th century gave us two great theories of physics: the general theory of relativity, which describes the behaviour of things on a very large scale, including the entire Universe; and quantum theory, which describes the behaviour of things on a very small scale, the sub-atomic world. The refusal of the Universe to reveal an equation that combines these two great ideas has caused some people to doubt our whole understanding of physics.
In this landmark new book, popular science master John Gribbin tells the dramatic story of the quest that has led us to discover the true age of the Universe (13.8 billion years) and the stars (just a little bit younger). This discovery, Gribbin argues, is one of humankind's greatest achievements and shows us that physics is on the right track to finding the 'Theory of Everything'.
13.8 provides an eye-opening look at this cutting-edge area of modern cosmology and physics, and tells the compelling story of what modern science has achieved — and what it can still achieve.

Цитаты

  • Vitalyцитирует9 лет назад
    When it is applied to describe anything less than an entire universe,c such as the nature of the orbit of Mercury about the Sun, this is really an approximation, although the approximation can be made as accurate as you like
  • Vitalyцитирует9 лет назад
    The difficulty in making these observations is highlighted by the fact that the apparent brightness of these stars, as seen from Earth, is less than one-billionth of the apparent brightness of the faintest stars visible to the naked eye.
  • Vitalyцитирует9 лет назад
    This gives an age for the disc of the Milky Way of 9.3 billion years, give or take a billion years or so.
