- Measurements and errorsEvery physical claim in this course rests on a measurement, and every measurement carries a stated or implied uncertainty. This topic is…
- Particles and radiationThis topic rebuilds matter and light from the ground up: the small set of fundamental particles everything else is made from, the exchange…
- WavesA wave transfers energy and information without transferring matter. This topic builds a common vocabulary — amplitude, phase, path…
- Mechanics and materialsThis topic is the mathematical backbone of classical physics: describing motion precisely, explaining what causes it to change, and…
- ElectricityCircuits are governed by two conservation laws in disguise: charge cannot pile up anywhere in a steady circuit, and energy transferred per…
- Further mechanics and thermal physicsThis topic extends mechanics to motion that repeats — circular motion and oscillation — and then moves from the mechanics of individual…
- Fields and their consequencesGravitational, electric and magnetic fields look like separate topics but share a common mathematical skeleton: a source creates a field,…
- Nuclear physicsThis topic returns to the nucleus itself: what the Rutherford scattering experiment revealed about its structure, why some nuclei are…
- Astrophysics optionThis optional topic turns the tools built across the rest of the course — waves, quantum phenomena, fields — outward, onto the problem of…
- Turning points in physicsThree episodes, forty years apart, each forced physics to admit that a settled picture was wrong: the atom was not indivisible, light was…
