A Gary Larson cartoon, in which a caveman points to a drawing of a Stegosaurus tail and says, โ€œNow, this end is called the thagomizer, after the late Thag Simmons.โ€

But without doubt, the single greatest moment is Morgan Freeman dramatically intoning that the spiked tail of the Stegosaurus is called โ€œthe Thagomizer.โ€ It is! And hereโ€™s why:

๐ŸงตFeels like shouting into the void, but it is essential to note that the Trump/Rubio gutting of the State Department and blowtorching of US diplomatic capacity and credibility is an accelerant to this spiraling war and will seriously undercut US/allied efforts to pick up the pieces after. 1/

The University of Texas System has passed a set of rules regulating the teaching of "controversy." The administration of each university in the system gets to decide what constitutes controversy. I've published an op-ed in the Austin Statesman respoonding.

Only once people admit that the entire Ukraine-Russia negotiations process being orchestrated by the USA/Trump is first and last a sham designed to help Putin as much as possible (and provide massive payoffs to the administration), will people be able to discuss it honestly.

A color-coded binary tree displaying how to expand (x+y)^3. There are 8=2^3 terms on the bottom, and by putting them in "alphabetical order" and grouping like terms, you see that (x+y)^3 = x^3 + 3x^2y + 3xy^2 + y^3.

My coauthor Dave Perkinson made this diagram to explain the binomial theorem and I think it's the perfect distillation. Here's our draft book, Discrete Structures, if you want more: kyleormsby.github.io/files/113spr... ๐Ÿงฎ

We've still never had a president born during that green era. Kamala Harris was born in that very first green square but before the Voting Rights Act; she's the only nominee born in the green.

(Me too! I was born in that last blue square. I'm old but I'm not *that* old...it's all so very recent).
