It was like a new world opened to me, the world of science, which I was at last permitted to know in all liberty.

I was taught the method for advancement is not quick or simple.

Pierre Curie voluntarily exposed his arm to the action of radium for several hours. This resulted in damage resembling a burn that developed progressively and required several months to heal. Henri Becquerel had by accident a similar burn as a result of carrying in his vest pocket a glass tube containing radium salt. He came to tell us of this evil effect of radium, exclaiming in a manner at once delighted and annoyed: "I love it, but I owe it a grudge."

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.

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.
