Nothing in life is to be feared. It is only to be understood.
In science, we must be interested in things, not in persons.
I never see what has been done; I only see what remains to be done.
A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales.
