What a chord looks like: sound waves, harmonics, and Fourier transforms
A C-major chord is both a complicated pressure wave and an orderly spectrum. Synthetic signals connect those views through harmonics, tuning, beats, and nonlinear mixing—then mark where acoustics stops explaining music.
One note in time and frequency
The same synthetic A4 appears as repeated pressure variation in time and concentrated magnitude at 440 Hz in frequency.
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.
