Az alexandriai iskola (E03)

In the beginning of today’s episode, we make the acquaintance of Aristotle. He established the peripatetic school. The idea of the school is for the student to learn as he walks around. Next, we get to know Alexander the Great, who was tutored by Aristotle as well, and who would conquer Egypt and found the city of Alexandria. Besides that, we also meet Ctesibius , an engineer, who would invent a magnificent water meter, and also pumps, the thermometer and the first air gun among many other things. Another new acquaintance will be Ptolemy. He would manage to create and draw extremely accurate maps. Another genius accrues from the school of Alexandria: Heron. He would invent a forerunner of the steam engine. (iTunes)
