向高处攀登的奋斗本身足以充实一个人的心灵。必须想象西西弗斯是幸福的。
"The struggle itself towards the heights is enough to fill a man's heart. One must imagine Sisyphus happy."
Young people must equip themselves for life's duties and guard against its temptations.
——致书蒋介石,1920年10月29日
The future of physics lies in our ability to manipulate processes that occur faster than we can currently measure.
