There are many ways of knocking electrons out of atoms. The simplest is to rub two surfaces together. ~ Fred Hoyle 1915 to 2001
Macroscopic objects as we see them all around us are governed by a variety of forces derived from a variety of approximations to a variety of physical theories. In contrast the only elements in the construction of black holes are our basic concepts of space and time. They are thus almost by definition the most perfect macroscopic objects there are in the universe. ~ Subrahmanyan Chandrasekhar 1910 to 1995

This most beautiful system of the sun planets and comets could only proceed from the counsel and dominion of an intelligent and powerful Being. And if the fixed stars are the centres of other like systems these being formed by the like wise counsel must be all subject to the dominion of One; especially since the light of the fixed stars is of the same nature with the light of the sun. ~ Isaac Newton 1642 to 1727
A fact acquires its true and full value only through the idea which is developed from it. ~ Justus von Liebig - 1803 to 1873

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
The chief philosophical value of physics is that it gives the mind something distinct to lay hold of which if you don’t Nature at once tells you you are wrong. ~ James Clerk Maxwell 1831 to 1879
The finding of the double helix thus brought us not only joy but great relief. It was unbelievably interesting and immediately allowed us to make a serious proposal for the mechanism of gene duplication. ~ James Watson 1928 – Present - Geneticist
