Domains of Physics
Interactive map of the 7 pillars of physics — mechanics, thermodynamics, EM, optics, relativity, quantum, nuclear.
Key Notes
Classical mechanics governs macroscopic, slow (v≪c), large (scale ≫ atomic) systems.
Thermodynamics deals with heat, work, and statistical behavior of large ensembles.
Electromagnetism unifies electric and magnetic phenomena (Maxwell's equations).
Optics is a special case of EM — wave + ray + quantum (photon) descriptions.
Special relativity kicks in for v comparable to c; General relativity for strong gravity.
Quantum mechanics governs atomic and subatomic scales.
Nuclear and particle physics probe the constituents of matter.
Important Points
These domains overlap — e.g. quantum electrodynamics unifies quantum mechanics and EM.
JEE covers all classical domains plus basic quantum and nuclear.
