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 Chemist Physicist
Geometry inasmuch as it is concerned with real space is no longer considered a part of pure mathematics; like mechanics and physics it belongs among the applications of mathematics. ~ Hermann Weyl 1885 to 1955 - Mathematician and Theoretical Physicist

Archimedes’ finding that the crown was of gold was a discovery; but he invented the method of determining the density of solids. Indeed discoverers must generally be inventors; though inventors are not necessarily discoverers. - William Ramsay 1852 to 1916 Chemist
Before the Copernican revolution it was natural to suppose that God’s purposes were specifically concerned with the earth but now this has become an unplausible hypothesis. If it is the purpose of the Cosmos to evolve mind we must regard it as rather incompetent in having produced so little in such a long time. ~ Bertrand Russell 1872 – 1970 - Mathematician and Philosopher
We cannot define anything precisely! If we attempt to we get into that paralysis of thought that comes to philosophers who sit opposite each other one saying to the other ‘You don’t know what you are talking about!’ The second one says ‘What do you mean by know? What do you mean by talking? What do you mean by you?’ and so on. ~ Richard Feynman 1918 to 1988
Why the dinosaurs died out is not known but it is supposed to be because they had minute brains and devoted themselves to the growth of weapons of offense in the shape of numerous horns. ~ Bertrand Russell 1872 – 1970 - Mathematician and Philosopher

Physics is very muddled again at the moment; it is much too hard for me anyway and I wish I were a movie comedian or something like that and had never heard anything about physics! ~ Wolfgang Pauli 1900 – 1958
