“Giving grace. Listening to a political opponent’s concerns. Finding common humanity. In 2020, these seem like radical propositions. But when it comes to changing minds, they work.”

I was trying to bring some order to my bookshelves when I came across my copy of “Littlewood’s miscellany” and started browsing. I promise I am never going to complain about my teaching load again. pic.twitter.com/XBw7KfxYMW

[1/2] Now that the ingenious @ChocoLinkage has posted linkages that compute both squares and cubes, I thought it would be fun to reverse-engineer the squaring one.
If you want to work through this in detail yourself, note that all lengths are multiples of 1/16.

Lecture 3 of computational algebraic topology is up! Here we meet Euler characteristics, chain complexes and homology. If you make it to the end, there's ONE WEIRD PICTURE THAT EXPLAINS EVERYTHING. OTHER IMAGES HATE IT.

may i suggest o-minimal structures? they give clear notions of definable sets, definable functions, & more. very nice to work with. the book by van den dries is an elegant & easy reading intro.

& now he's gone.
i've been so lucky to have the chance to pay it forward by teaching lots of engineering students calculus.
(& not minding being thought of as weird)
i've been so lucky to have a job where i can find new things too, sometimes.

i never thought about being a mathematician -- even the idea of going to graduate school was not part of my culture growing up. but henry wente more than anyone taught me that there's this vast unknown world of crazy objects that we can just barely imagine with enough effort.

henry wente was the first person who taught me that mathematicians do research -- that there's more to discover -- that even when the rest of the world says a thing shouldn't exist, it may yet be found.

it took time, but i stopped thinking of him as a comic calc prof, and started getting to know him. he was an amazing teacher & i learned so much from him.
so, i took more classes from him.
i took 12 classes from him.
anything i could get.

henry wente worked on this tirelessly while he was a tenure-track professor at tufts (iirc). he was turned down for tenure. thankfully, the university of toledo gave him a position. he stayed at toledo for the rest of his career.
