Galileo Galilei

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

All truths are easy to understand once they are discovered; the point is to discover them.

We cannot teach people anything; we can only help them discover it within themselves.

Portrait of Galileo Galilei

Galileo Galilei (1564 – 1642) was an Italian physicist, mathematician, astronomer and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. He is perhaps responsible more than any other single person, for the birth of modern science.

Mathematics is the language in which God has written the universe.

The increase of known truths stimulates the investigation, establishment and growth of the arts; not their diminution or destruction.

There are those who reason well, but they are greatly outnumbered by those who reason badly.
