    Actually it's not so bad: start with Hawaiian earring and loop L_n around the n-th circle. Attach pair of pants P_n to H where the belt of P_n is attached by L_n. One ankle is attached by L_{2n} and the other is attached by L_{2n+1}. It has some really fascinating properties

    After taking a little break from research, I have a full day tomorrow to work. Do I turn a mostly-finished project into a paper or spend all day on a shiny new problem that's caught my eye?

    It's just a continuous image of [0,1]... nbd.

    Just in case you didn't use unique path-lifting today.

    Meet the Hawaiian mapping torus - the mapping torus of the shift map. First singular homology is infinite cyclic generated by inner loop. Can you find the non-trivial elements of H_2? If you look at the image, it might feel H_2 is trivial since there is no "enclosed space!"

    The Eckmann-Hilton Argument! The higher homotopy groups are not just commutative but are "infinitely" commutative...whatever that means🙃

    Some groups are just so misunderstood.

    I found this giant relic in a room I teach in. I assume an archeologist left it here on accident.

    Whoops. Ok so apparently he's dh-ing
