It is my earnest desire that some of you should carry on this scientific work and keep for your ambition the determination to make a permanent contribution to science.

You cannot hope to build a better world without improving the individuals.

I am among 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. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery has its own beauty.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

Each of us must work for his own improvement, and at the same time share a general responsibility for all humanity.

We must not forget that when radium was discovered no one knew that it would prove useful in hospitals.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.
