Thales of Miletus (circa 624–546 BCE) was a pre-Socratic Greek philosopher, mathematician, and astronomer from Miletus in Asia Minor (modern-day Turkey). He is often regarded as one of the Seven Sages of Greece and is credited with being the first philosopher in the Western tradition. Here are some key points about Thales:
- Philosophy and Cosmology: Thales is considered the founder of the Milesian School of natural philosophy. He is known for proposing that water is the fundamental substance (arche) of the universe, suggesting that everything is derived from water in some form.
- Mathematics: Thales is famous for his work in geometry. He is credited with several geometric principles, such as the theorem that states a circle is bisected by its diameter and the concept that the base angles of an isosceles triangle are equal.
- Astronomy: Thales made significant contributions to astronomy. He is believed to have predicted a solar eclipse that occurred on May 28, 585 BCE, and introduced the idea that the year has 365 days.
- Practical Contributions: Thales was also involved in practical applications of his knowledge. He is said to have used his understanding of geometry to measure the height of the pyramids in Egypt by comparing their shadows with his own.
- Legacy: Thales’ emphasis on seeking natural explanations for phenomena, rather than relying on mythology, laid the groundwork for the development of scientific and philosophical inquiry in ancient Greece.
Thales’ work and ideas have had a lasting influence on the fields of philosophy, science, and mathematics.
