gollark: You should eigenlearn eigenlinear eigenalgebra.
gollark: Did you know? Eigendecomposition is a way to represent a matrix in terms of eigenvectors and eigenvalues.
gollark: Since the entire thing is horrible discrete approximations anyway.
gollark: I basically just have to divide the force by γ³ as long as the box is ticked.
gollark: It turns out that implementing special relativity is very easy (since it's rendered from the reference frame of the ground or something).
