Pre-Socratic Philosophers

Thales

The first named Western philosopher and scientist. Of the Ionian school, he was born at Miletus and travelled widely in Egypt and to Babylon, where he learned techniques of land surveying ('geometry') and astronomy. He is said to have invented formal geometry as we know it, by formalizing empirical measuring techniques. He is also supposed to have predicted the solar eclipse of 585 B.C. He held that all things are made of water; and he investigated magnets, suggesting that they were alive, with mind, as they moved each other.

Thales had predicted this solar eclipse. The Seven Sages were most likely already in existence, as Croesus was also heavily influenced by Solon of Athens, another sage. Whether Thales was present at the battle is not known, nor are the exact terms of the prediction, but based on it the Lydians and Medes made peace immediately, swearing a blood oath.

Thales was known for his innovative use of geometry. His understanding was theoretical as well as practical. Thales understood similar triangles and right triangles, and what is more, used that knowledge in practical ways. he measured the height of the pyramids by their shadows at the moment when his own shadow was equal to his height. A right triangle with two equal legs is a 45-degree right triangle, all of which are similar. The length of the pyramid’s shadow measured from the center of the pyramid at that moment must have been equal to its height.

I think that Thales findings and the way his mind worked is totally amazing. When he predicted the solar eclipse, you have to have a passion for numbers and science and to show that much heart means you are good at what you do and want to exceed every time you use your skills.
