(330–275. B
Greek mathematician Euclid is the founder of the mathematical school of Alexandria. He is the author of The Elements, the most important textbook in the history of geometry. Besides mathematics, he studied optics, astronomy and music.
No Royal Road for the King Discouraged by the difficulties he encountered in his studies of Euclid’s geometry, King Ptolemy once said: - Is there an easier way to learn geometry? - There’re no royal roads in geometry – Euclid replied.
Reason When he learned his first theorem, a student once asked Euclid: - What do I have of my knowledge of this? Euclid called a slave and instructed him: - Bring this man three small coins. His reason for learning is profit!
