Someone wrote to me out of the blue with a mathematical question. Though the statement of the problem was not clear enough for me to solve it, I told him how I’d approach it, and he was happy.
I asked how he found me.
Anton, I was surfing the web, some site came up — cant recall which one, it listed you as a respected expert,
which was the best laugh I’d had all day.
Since the problem had to do with sphere packing, perhaps he found a link to my (loosely related) spherical arrangements page.
