The model worked with physical links, such as balls and sockets and hooks and eyes, to show in detail how connections happened between them. Around 500 BCE, two theories existed regarding the composition of the universe.

He taught that there were four elements that composed all materials that could be found on Earth. LEUCIPPUS AND DEMOCRITUS. The equation can be solved exactly for an atom containing only a single electron (hydrogen), and very close approximations can be found for atoms containing two or three electrons (helium and lithium, respectively).
