PhysicsHub
From Newton's apple to quantum superposition - the complete physics reference. Laws, equations, constants, and the physics you need to understand the universe.
โ๏ธ Physics Topics
Six major branches of physics - each with laws, equations, and real-world applications. Click any card for the full deep-dive.
Mechanics describes how objects move under the influence of forces. From Newton's laws governing everything from falling apples to orbiting planets, t...
Waves transfer energy through space without transferring matter. Sound, light, radio, seismic waves, and quantum probability amplitudes are all descri...
Electricity and magnetism are two aspects of a single electromagnetic force. Maxwell unified them in 1865. Virtually all modern technology - from powe...
Quantum mechanics describes reality at the smallest scales. Particles behave like waves, have quantised energy, and can exist in superpositions of sta...
Special relativity (1905) showed that space and time are relative, and mass and energy are equivalent. General relativity (1915) revealed gravity as t...
Nuclear physics studies the structure and reactions of atomic nuclei. It underpins nuclear power, nuclear medicine, understanding of stars, and the or...
๐ Physical Constants
The fundamental constants of nature - the numbers that define the universe. Memorise the most important ones; use this page for the rest.
Physics meets nuclear science
Nuclear physics is the bridge between PhysicsHub and NexoHub. From radioactive decay to reactor physics to the binding energy curve - it's all here.
