Professor， the forth question is from Zhang Shoucheng， Professor of Physics， Stanford University：
“If you were to tell aliens about the highest achievements of our human civilization on the back of one envelope， what would you write ？”
教授，第四个问题来自于斯坦福大学物理学教授张首晟
“如果让你告诉外星人我们人类取得的最高成就，写在一张明信片的背面，您会写什么？”
It is no good telling aliens about beauty or any other possible art form that we might consider to be the highest artistic achievement， because these are very human specific。 Instead I would write about Godel’s Incompleteness Theorems and Fermat’s Last Theorem.These are things aliens would understand。
告诉外星人关于美，或者任何可能代表最高艺术成就的艺术形式都是无益的，因为这是人类特有的。我会告诉他们哥德尔不完备定理和费马大定理。这才是外星人能够理解的事情。
The next question is from myself：
“We wish to promote the scientific spirit at all 9 GMIC conferences globally。 What three books do you recommend technology leaders read to better understand the coming future and the science that is driving it？”
下一个问题来自我自己：
“我们希望提倡科学精神，贯穿GMIC全球九站，清您推荐三本书，让科技届的朋友们更好的理解科学及科学的未来。”
They should be writing books not reading them。 One fully understands something only when one has written a book about it。
他们应该去写书而不是读书。只有当一个人关于某件事能写出一本书，才代表他完全理解了这件事。
The next question is from Weibo user：
“What is the one thing we should never do in life， and the one thing we should all do？”
下一个问题来自于微博用户
“您认为一个人一生中最应当做的一件事和最不应当做的一件事是什么？”
