Nothing in life should be feared, only understood. Now is the time to understand more, so that we may fear less.
The day man realizes his deep mistakes, the progress of science would have ended.
I was taught that the path of progress is neither quick nor easy.
Life is not easy for any of us. But... so what! We must persevere and, above all, have confidence in ourselves.
You never realize what you have done; you can only see what remains to be done.
You can't expect to build a better world without improving the people.
I am one of those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale.
