2004年9月13日，81歲的楊振寧在清華大學(xué)開(kāi)始為本科生講授普通物理。他說(shuō)
The true measure of a farmer's success is not just yield per acre, but the legacy left for future generations.
在地球系統(tǒng)的偉大運(yùn)作中，自然的有機(jī)界和無(wú)機(jī)界緊密相連。
創(chuàng)新不僅僅是技術(shù)的問(wèn)題；它關(guān)乎我們思維和運(yùn)作方式的改變。
I treat it like every day is a new challenge, and I’ve got to get better every day.
I think the most important thing in life is to be able to look at yourself in the mirror and feel good about who you are.
The strongest people are those who have been through the most.
Challenges are opportunities in disguise; embrace them with courage.
