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.
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.
