Anaximander explained to kids

Anaximander was a pre-Socratic Greek philosopher who lived in the 6th century BC. He is credited with being the first philosopher to propose that the universe began with an infinite, undifferentiated mass, which he called the "apeiron". He also proposed that the primary elements of the universe were earth, air, fire, and water. Anaximander was born in Miletus, Ionia (modern-day Turkey) around 610 BC. He was a student of Thales, the first Greek philosopher, and is considered to be part of the Milesian school of thought. Anaximander's ideas about the universe were very influential, and helped to pave the way for the development of scientific thought. Some of Anaximander's other notable ideas include the belief that the earth is suspended in space and does not rest on anything, and that the stars are made of fire. He also proposed that there are an infinite number of worlds, and that our world is just one of them. Anaximander's work was largely lost after his death, but was rediscovered in the 20th century. His ideas about the universe continue to be studied and debated by philosophers and scientists today.
