I'm finishing a B.S. in math and have been getting a bit more into physics lately. I'm on track for a second major in either physics or Russian, but not super concerned about finishing - I'm applying to grad programs in pure math. I'm particularly interested in algebraic geometry, combinatorics, mathematical cryptography, and translation. I'm not sure what the point of introductions normally is, but it'd be nice to find anyone whose interests intersect mine, book recommendations, whatever.
