My mind is my weapon. My brother has his sword, King Robert has his warhammer, and I have my mind... And a mind needs books as a sword needs a whetstone, if it is to keep its edge.
All my life through, the new sights of Nature made me rejoice like a child.
The most important thing in science is not to solve problems, but to ask the right questions.
你的太阳无法照耀是因为我。
人生就像一场逆行的旅程,我也是其中的一个过客。
