All objects that we see around us are made of protons, neutrons and electrons. At a deeper level, the protons and neutrons have also been shown to be made of quarks. It behooves us to ask whether the electron and the quarks have themselves substructure. So far, there is no evidence for such substructure, despite particle physics experiments that probed the structure of matter at distances billions of times smaller than the atoms. I will discuss some theoretical ideas about possible constituents of the particles currently considered elementary (electron, quarks, neutrinos, etc.) that can be probed in upcoming experiments.
