So I already completed the musicwayback challenge a few days ago but I still want to share my songs in the unknown genre of maths songs.

Finite simple group of order 2 - Klein four group

A klein four group is actually a group of order 4 (this means it contains 4 elements) ironically the group consists out of 5 people. I won't delve into the mathematical definition of a finite simple group but instead just give you the simplest example of a finite simple group which is Z/2Z where Z are the integers. It contains the elements 0 mod 2 and 1 mod 2. So there are only 2 elements like a love pair. Hence, it is of course a love song:

Peace for triple piano by Vi Hart

Not so much a mathematical song by lyrics but by use of a complex projection. Anyway without understanding the math you can enjoy the song (don't forget to move the camera around) :D

If you want to learn more about the math and how it was made click here.

For every delta there is an epsilon by Tom Lehrer

Tom Lehrer has many math and science songs. But of course I love the unknown ones he has written. I actually couldn't find a recording of my favorite Tom Lehrer song on Youtube. However, you can listen to this song on this website -> https://ww3.haverford.edu/physics-astro/songs/lehrer/delta.htm It about the famous delta-epsilon continuity definition which many a science student is presented in their first math course at university. The song describes the sad life of all those deltas smaller than zero which have no epsilon.

SHAMELESS PROMOTION

There is a MathOwl shop which sells my artsy fartsy stuff. If you got some spare money head over there. You can get complex t-shirts over here. I also have really cheap stuff available like these stickers They are an absolute hoot.
