The amount of heat energy radiated by an object is proportional to the temperature raised to the fourth. You can predict idealized non-light-reflecting object's varying radiation based on the temperature. The Rayleigh-Jeans Law predicts that a higher frequency of light increases the intensity of the blackbody radiation. The Ultraviolet Catastrophe predicts a continuous quadratic increase in radiation intensity with respect to frequency, assuming that light is a wave, but experiments showed the summation leading to infinite power, contradicting the theory of conservation of energy. Planck's Law says electromagnetic energy comes in discrete quanta = τħf. Photoelectric effect and work function. p=τħ/λ De Broglie's wave-particle duality. Diffraction pattern on double-slit experiment due to superposition and Interference. Schrodinger equation used for probability density function. Measurement is weird, like Schrodinger's cat. Heisenberg Uncertainty principle. You can only know the position and momentum or time and energy of a particle up to a certain precision. Further knowledge of the momentum treats it as a wave and loses knowledge of the position, and further knowledge of the position treats it as a particle and loses knowledge of the momentum. Consider wave packets. There is a limit to measuring the universe.

Quantum electrodynamics is a field theory.
