Plato and Kepler were in the right ball-park, but not really right.  Both the solar system and atoms are described pretty well by similar laws—the inverse-square force laws for gravity and electrostatics. And solving this problem (in either the classical or quantum case) does indeed require a deep understanding of rotations in 3-dimensional space.  …[T]he Platonic solids have as their symmetries finite subgroups of the rotation group in 3 dimensions…. [T]he real reason the inverse square force law problem is exactly solvable is a surprising symmetry in four-dimensional rotations.

I really want Henry, Siwon, Donghae and Eunhyuk to form an official subgroup. So Cold is still one of my favorite suju songs, and I love their styles together so much!

Also I want a subgroup with Heechul and Henry and Zhou Mi, idc who else but I need these three to promote together!

also i really really want a vocal subgroup of zhou mi, sungmin and kangin but i know it’s not gonna happen cuz kangin and stuff
