Applied physics

Fluids, heat engines, and DC circuits: the three languages working machines actually speak.

1. 1FluidsPressure, buoyancy, and Bernoulli — why pipes neck down and wings remember they are fluids.16 min
2. 2Heat and enginesThe first law is bookkeeping. The second law is why you cannot bookkeep your way to 100%.16 min
3. 3DC circuitsBenchCharge, potential, resistance. Kirchhoff’s two rules are Newton and energy, in electrical clothes.16 min
