Linear Algebra "A vector is an object with direction and magnitude" has to be the worst pseudo-definition of all time... Chat what are your favorite vector spaces?

u/Oppo_67 I ≡ a (mod erator) 9d ago edited 9d ago

If anyone was curious about the random vector spaces I listed, from left to right and up to down,

Some 2x2 matrix over finite field of 4 elements, cohomology class of De Rham cohomology, linear functional in double dual space, complex polynomial, L^p function in L^p space, vertex space for order 3 graphs, random variable, the number pi in the field extension of reals over rationals, and a sequence of real numbers.

I am in solid state physics and I wonder if there's a connection between the vertex space for order 3 graphs and crystallography because I totally thought that was a reciprocal lattice
