When you hear a physicist invoke the uncertainty principle keep a hand on your wallet. ~ David Griffiths b. 1942
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

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
In my experience most mathematicians are intellectually lazy and especially dislike reading experimental papers. ~ Francis Crick 1916 – 2004 - Molecular Biologist
Trial by combat of wits in disputations has no attraction for the seeker after truth; to him the appeal to experiment is the last and only test of the merit of an opinion conjecture or hypotheses. - Joseph Mellor 1869 to 1938 Chemist
Benjamin Franklin performed a beautiful experiment using surfactants; on a pond at Clapham Common he poured a small amount of oleic acid a natural surfactant which tends to form a dense film at the water-air interface. He measured the volume required to cover all the pond. Knowing the area he then knew the height of the film something like three nanometers in our current units. ~ Pierre-Gilles de Gennes 1932 to 2007
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
I see some parallels between the shifts of fashion in mathematics and in music. In music the popular new styles of jazz and rock became fashionable a little earlier than the new mathematical styles of chaos and complexity theory. Jazz and rock were long despised by classical musicians but have emerged as art-forms more accessible than classical music to a wide section of the public. Jazz and rock are no longer to be despised as passing fads. Neither are chaos and complexity theory. But still classical music and classical mathematics are not dead. Mozart lives and so does Euler. When the wheel of fashion turns once more quantum mechanics and hard analysis will once again be in style. ~ Freeman Dyson b. 1923 - Mathematician and Physicist
No two electrons in the same state? That is why atoms are so unnecessarily big and why metal and stone are so bulky. (Explaining that atoms are as large as they are because of Wolfgang Pauli’s Principle.) ~ Paul Ehrenfest 1880 – 1933
