Atoms are made of electrons, protons and neutrons. Protons and neutrons are in turn made up of quarks. These are just some of the elementary particles that make up the foundation of modern particle physics. But how do we know about these particles when we can't see atoms directly, much less their constituents? One of the early methods was through a device known as a cloud chamber, and it is quite a clever invention.
