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.” ~ Marie Curie 1867 to 1934

But though the professed aim of all scientific work is to unravel the secrets of nature it has another effect not less valuable on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent. ~ James Clerk Maxwell 1831 to 1879
