His favorite book is hot all over the world.


《 A brief history of time 》
在经典的广义相对论的框架里，霍金和彭罗斯证明了，在很一般的条件下，时空一定存在奇点，最著名的奇点即是黑洞里的奇点以及宇宙大爆炸处的奇点。在奇点处，所有定律以及可预见性都失效。
In the frame of classical theory of relativity , hawking and Ross has proved that in a very general conditions, the space must exist singularities, the most famous singularity of a black hole is a singularity and cosmic explosions of singular. In the law, all the singularity predictability is invalid.
Black holes theory----黑洞理论
黑洞理论是一个复杂的关于宇宙语时空的科学体系。
霍金用一个手指完成了爱因斯坦没有完成的工作。
Some of his sayings
When you are faced with the possibility of mortality, you realize that life is precious, and you have a lot of things to do. 当你面临着夭折的可能性，你就会意识到，生命是宝贵的，你有大量的事情要做。

God created both a genius, but also to create a fool, which does not depend on natural, individual effort is the reason for completely different results.上帝既造就天才，也造就傻瓜，这不取决于天赋，完全是个人努力程度不同的结果。

If a man does not have a dream, is dead .如果一个人没有梦想，无异于死掉.

Life is not fair, regardless of your circumstances, you can only do your best. 生活是不公平的，不管你的境遇如何，你只能全力以赴。
