Today I said "using root notation and fractional powers in the same expression is like changing the font in the middle of a word." This clearly resonated as many students visibly cringed.

Went over a problem in calculus discussing a function f(x) that reports the value of a house located x feet from the beach. I'm not sure the sign of df/dx is the same as it was two weeks ago.

All natural numbers are interesting. Proof: Suppose not. Let n be the smallest uninteresting number. But that's interesting! Contradiction. #proofinatweet

#mathprints for a multivariable calculus classroom activity, or possibly a scale model of a Romulan city.

New medication has uncontrollable hiccups as a side effect. Just in time for the first day of teaching tomorrow.

Tricky math puzzle: Suppose we have a disk of diameter 20 and strips of width 1 and length 20. We can cover the disk using 20 strips by laying them side-by-side. Can we do it with 19? No cutting is allowed. My next tweet is the answer/solution. 1/6

Circles are boring. Let's break them by changing those 2's in the Pythagorean theorem to 4's. Or 1's. Or ∞'s. Then you have new geometries, new square-like circles, new trig functions & new π's. Check out our forthcoming book on #squigonometry! amzn.to/3pnSJwe

My daughter made a little table out of an aborted 3D print. It appears that her dollhouse will be largely furnished with 3D printer prototypes and failures.

A moment's thought and I'd have printed this in two halves. Tried freeing the bottom half from support jail just to see if I could. All I made was a huge mess. #mathprints

Teaching mutivariable calculus for the 1st time in a while this fall. Got a new 3D printer to up my manipulatives game. Meet my first #mathprint, r=1+(sin^2(2ϕ))-cos^2(θ)
