Why a microwave oven is not tuned to water
A microwave oven heats liquid water through dielectric relaxation, not a narrow resonance. A traceable single-Debye calculation separates the dielectric-loss-factor peak from attenuation, quantifies a pure-water baseline, and shows why the same idealized channel is weak in ice.
A light wave from Maxwell's equations, rendered in pure TikZ
Deriving the electromagnetic plane wave from Maxwell's equations, then drawing it with build-time TikZ — and the Haskell pipeline rebuild (lualatex + dvisvgm) that finally renders its transparency.
Determination of SI Units for Magnetic Interactions in Quantum Mechanical Calculations
A systematic derivation of the SI units involved in magnetic interactions at the quantum level, focusing on the correct dimensional analysis of magnetic moments, fields, and coupling constants.
