This means that we have here an entirely separate kind of chemistry for which the current tool we use is the electrometer, not the balance, and which we might well call the chemistry of the imponderable.

When one studies strongly radioactive substances special precautions must be taken. Dust, the air of the room, and one's clothes, all become radioactive.

Stability can only be attained by inactive matter.

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.

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

You cannot hope to build a better world without improving the individuals. To that end each of us must work for our own improvement, and at the same time share a genaral responsibility for all humanity, our particular duty being to aid those to whom we think can be most useful.
