Thales from Miletus   Thales from Miletus (625 - 545 B.C.) (as one of the first Greek thinkers) started to considerate the structure of the world. What he is very well known for is that he noticed and described the electrical influence of amber electrified by rubbing (anyway it is quite a god way to check if it's a real amber you have bought: rub it quite fast with a piece of wool and then place it near your hair. If the stone doesn't attract your hair - sorry but it isn't a real amber). He also recognised water as a basic substance occurring in nature thinking it was an original and final element. Life also descended from water which in turn was as he said a source of all motion. For Thales water had all needed features to let the whole nature develop. He was wrong of course but just think - after all he discovered the importance of motion and he considered the nature of force! Did you know that he came to the conclusion that force is united with matter?!
