In quantum mechanics, the magnetic field says how much the phase of a charged particle rotates when you move that particle around a loop!

(Not counting other effects.)

This means that the magnetic field is fundamentally something you want to integrate over a surface.

Please enjoy this awesome video of the HR 8799 system made by Jason Wang, for anyone who hadn't seen it yet.

The star itself was blocked by the telescope so we can see the planets, though some of the light still scatters around the edges. All four known planets are visible. The orbital motion is interpolated from a series of images taken by the Keck Telescope in Hawaii.

For a $$n\times n$$ grid, the lights out game can be considered as solving a linear system over $$n^2$$ variables in mod $$2$$. It takes $$O(n^6)$$ time. Surprisingly, there is a $$O(n^3)$$ time algorithm. chaoxuprime.com/posts/2019-01-
