Thales of Miletus was a Greek mathematician, astronomer and a pre-Socratic philosopher from Miletus in Ionia, Asia Minor. He was one of the Seven Sages of Greece.
Many, most notably Aristotle, regarded him as the first philosopher in the Greek tradition, and he is otherwise historically recognized as the first individual in Western civilization known to have entertained and engaged in scientific philosophy.
Thales is recognized for breaking from the use of mythology to explain the world and the universe, and instead explaining natural objects and phenomena by naturalistic theories and hypotheses, in a precursor to modern science.
According to Herodotus, Thales predicted the solar eclipse of May 28, 585 BC. Thales also described the position of Ursa Minor, and he thought the constellation might be useful as a guide for navigation at sea. He calculated the duration of the year and the timings of the equinoxes and solstices. He is additionally attributed with the first observation of the Hyades and with calculating the position of the Pleiades.
All of this, 2600 years ago. In a way of saying, Thales of Miletus brought Science into existence.
Thales gave quite a few theories.
For example, rather than assuming that earthquakes were the result of supernatural whims, Thales explained them by hypothesizing that the Earth floats on water and that earthquakes occur when the Earth is rocked by waves.
And that suggests how he was on the right track but not completely right.
He also used to believe that the matter was alive and contained souls.
Well, that was really preposterous but still, he was light years ahead of his time.
Point being, 2600 years ago, matter was thought to be alive and to contain souls.Hundreds of years later, we proved that wrong. We proved the actual nature and existence of matter all across the Spacetime.
So, I’d say, it would be safe to assume that we can prove a lot of other things that we haven’t been able to prove as of now.
P.S. Everything has a reason. Every question has an answer. You just need to be smart enough.
