## Questions

### Physics⚛

#### Reversibility in double slit experiment - Is the experiment reversible?

possible solution

### Programming🌲

#### gamut equilizer for color blind display?

some sun glasses were release recently which filter certain frequency that allow people with some forms of color blindness to see more normally. Why not use that principle to balance the gamut on computer displays? look into source for redshift, to see what they're doing.

#### Screaming fast regex using hash maps as underlying sequence?

explore this later. Map Char (Set (Array Index)) explore this later, but the idea is loading the string into a map would take $$O(n)$$, but then \$O(1) for any single char lookup on indices.

### Math🐚

#### Compass Vectors - <N, S, E, W> [2018-10-04 Thu 09:50]

these are useful for CellPU, not sure how they work, but they are defining relative cell offsets. So, a 4D discrete vector embedded in 2-space.

#### General algebraic irreducibility

The idea with that, prime numbers are numbers that are irreducible on naturals under multiplication, but generally $$X∊S$$ are irreducible for S under some $$*$$? Things that just can't be reduced in some circumstances, seems to pop up all over the place.

#### Stereo Spheres volumetric projection with nested shell stacking

stereographic projection for filled spheres

#### Huffman coding of cyanobacteria base pairs subsequences?

Would that huffman tree highlight any important structures?

### Economics

### Composition

Here's a rule based search tool for exploring the space of chord changes which attempts to answer the question: The current chord is X, what chord should follow X? The user specifies predicate for the next chord, like "No 11th chords" or "Only chords with less than 4 notes" or "Shares at least 2 notes with previous two chords".
