Thoughts on Mathematics

Mathematics is the language with which God has written the universe.
- Galileo Galilei (1564/1642)

I have hardly ever known a mathematician who was capable of reasoning.
- Plato (427—347 B.C.E.)

Mathematics is the queen of the sciences.
- Carl Friedrich Gauss (1777/1855)

There is geometry in the humming of the strings, there is music in the spacing of the spheres (planets).
- Pythagoras (569/500 B.C.E)

The laws of nature are but the mathematical thoughts of God.
- Euclid( c. 300 B.C.E)
