About This Lesson
Empedocles was an ancient Greek Philosopher and the first Western thinker to propose that everything in the world was a mixture of basic substances. He believed the four elements were Earth, Air, Fire and Water.
In this podcast we also look at physically un-mixing, or separating out mixtures into their basic substances.
