A huge thanks to Ava Serrano from New Jersey for composing the new theme song.

Today we venture back to the start of philosophical thinking. We will learn about two Greek thinkers who started to try and comprehend the universe. What was the Arche? How did their ideas fare to modern science? And how far off were they?
