I never see what has been done; I only see what remains to be done.

Just remember you will find that one special love that you know is right but for some reason just doesn't last

When one studies strongly radioactive substances special precautions must be taken if one wishes to be able to take delicate measurements. The various objects used in a chemical laboratory and those used in a chemical laboratory, and those which serve for experiments in physics, become radioactive in a short time and act upon photographic plates through black paper. Dust, the air of the room, and one's clothes all become radioactive.

Life is not easy for any for us.

The sensitive plate, the gas which is ionised, the fluorescent screen, are in reality receivers, into another kind of energy, chemical energy, ionic energy... luminous energy.

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

In science we must be interested in things, not in persons.
