1. 01

   Special relativity and invariant intervals

   Special relativity describes inertial-frame transformations with invariant vacuum light speed. It replaces Galilean transformations when relativistic effects matter.

   Quantum states, amplitudes and measurement

   A normalized state vector encodes probability amplitudes. Overall global phase leaves measurement probabilities unchanged.

   Schrodinger equations and a particle in a box

   The time-dependent equation is iℏ ∂ψ/∂t=Hψ. A time-independent Hamiltonian permits stationary-state analysis.
