每一次发现都是向理解宇宙迈近的一步。
"Every discovery is a step closer to understanding the universe."
I never know what I think about something until I read what I've written on it.
真理不是可证明的，而是不可避免的。
珍贵的宝物容易求得，而真心相待的郎君却难以寻觅
Every tree planted today is an investment in a greener tomorrow.
The most exciting discoveries are those that challenge our assumptions.
