At the smallest currently accessible scales the best we have is the Standard Model of Particle Physics. No Quora answer can provide a detailed description of this model, but you can easily search for background information and find such information for many levels of mathematical sophistication. For a solid understanding you will need to understand calculus, statistical physics, group theory, quantum field theory and a lot more mathematics.
