We, the human beings, and the objects around us in this world are all made up of matter. Matter can be broken down to smaller constituents (Molecules, Atoms, Protons, Neutrons, Electrons etc.). Subatomic particles like protons and neutrons can be further broken down to minute constituents called quarks. Today we have very good understanding of this subatomic world, the types of particles and the laws of nature that govern their behavior. In this course, Rohin hopes to share the excitement and mysteries in the subatomic world. Also the machines and tools that help us to study subatomic particles would be deliberated upon.
