Tell me everything you know about Euklid, Pythagoras etcetera.
I'm about to begin reading about greek algebra used in calculating geometric figures. After reading I'm going to write a 15-20 pages report.
So any kind of introduction would be awesome, I'm primarily interested in Euklid and how the theories at that time are important in math today.
ps. sorry for the bad english, I'm tired, made a 300 words spanish assignment and I'm not a native. Be nice, it's my first time.
