Hurrah, we come to the end of the module! You now know the answer to the question we asked about what would happen if we keep splitting a small object. We will eventually reach an atom.
The concept of an Atom is perhaps the most important discovery of Science. Don't believe us? Here is what Physics Nobel-prize winner Richard Feynman had to say about the atom:
"If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied."
