Visualization
Nice visualization of Hilbert Curves and Linear Algebra.
I like this comment by "matoma" in Abstract Vector Space:
Furthermore, why does the exponential function appear everywhere in math? One reason is that it (and all scalar multiples) is an eigenfunction of the differential operator. Same deal for sines and cosines with the second-derivative operator (eigenvalue=-1).
Noting the definition of Eigenfunction
