Fourier series, from the heat equation to sines to cycles.

The general uncertainty principle, about the concentration of a wave vs the concentration of its fourier transform, applied to two non-quantum examples before showing what it means for the Heisenberg uncertainty principle.

The heat equation, as an introductory PDE.

In the aftermath of the revolutions and upheaval in 18th and early 19th century Europe, there was a hunger for reform across the continent. Reformers like Robert Owen, Charles Fourier, and Auguste Comte proposed radical new ideas, and at...
