“记住要仰望星空，不要低头看脚下。 无论生活如何艰难，请保持一颗好奇心。” 史蒂芬·威廉·霍金 Stephen William Hawking 1942年1月8日-2018年3月14日
分享歌词： We go about our daily lives understanding almost nothing of the world.
We give little thought of the machinery that generates the sunlight and makes life possible.
To the gravity that glues us to the earth that would otherwise send us spinning off into space.
Or to the atoms that which we are made.. and on who’s stability we fundamentally depend.
Few of us spend much time wondering why nature is the way it is.
Where the cosmos came from.
Whether it was always there.
If time will one day flow backward.
Or whether there are ultimate limits to what humans can know.
What is the smallest piece of matter.
Why we remember the past and not the future.
And why there is a universe.
