不可能与可能之间的区别在于一个人的决心。
Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
Science is not just about theory; it's about making things that work in the real world.
Gather ye rosebuds while ye may,Old time is still a-flying,And this same flower that smiles today,Tomorrow will be dying.
