Surely it is not knowledge but learning; not owning but earning; not being there but getting there; that gives us the greatest pleasure. ~ Carl Friedrich Gauss 1777 – 1855 - Mathematician and Physicist
On the principle of successive variations not always supervening at an early age and being inherited at a corresponding not early period of life we can clearly see why the embryos of mammals birds reptiles and fishes should be so closely alike and should be so unlike the adult forms. ~ Charles Darwin 1809 to 1882 - Naturalist Evolutionary Biologist

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
Mathematics is the language in which the gods speak to people. ~ Plato c. 427 BC – c. 347 BC - Mathematician and Philosopher
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
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
There may be babblers wholly ignorant of mathematics who dare to condemn my hypothesis upon the authority of some part of the Bible twisted to suit their purpose. I value them not and scorn their unfounded judgment. ~ Nicolaus Copernicus 1473 – 1543 Mathematician and Astronomer
Our thoughts visions and fantasies have a physical reality. A thought is made of hundreds of electrochemical impulses. ~ Carl Sagan 1934 to 1996 Astrobiologist Planetary Scientist
Simple laws can very well describe complex structures. The miracle is not the complexity of our world but the simplicity of the equations describing that complexity. ~ Sander Bais b. 1945 - Theoretical Physicist
