Exponentiating (with base 10).
We had a guy retire a while back who had fifty years.
I always talk about the limit as x —> a as what the function looks like it’s going to do and f(a) as what the function actually does. Then a continuous function is one that does what it looks like it’s going to do.
I’m fine with that characterization. That’s the way they grow. Squares, however, don’t have a natural orientation.
Nicely done.
Quantum tunneling.
Nice! Is that Fairfield Circuitry a Barbershop? How do you like it?
A guitar pedalboard with a variety of pedals (somewhat sloppily) wired together
Nice. I’ve had a similar project:
Ah, thanks for that.
That’d be an interesting poll: “scratch” or “scrap,” and location (or hometown).
Alright, #ITeachMath and #EduSky:
Is it “scrap paper” or “scratch paper?”
TikZ is my favorite tool.
Check out this (super-helpful) guide:

An animation showing the generation of the graph of a polar function with the associated rectangular function overlayed to one side, showing the connection between the height of the rectangular function and the radius of the polar one
This was a fun @desmos.com graph to whip up, helping a student make the connection between rectangular and polar functions.

A 3-dimensional graph of a hyperbolic surface with the contour map and gradient for it projected onto the xy-plane
Had fun making a surface/contour map/gradient generator in
@desmos.com 3D with my Multivariable students. This one's easily customizable.

A 3-dimensional plot of the grid curves of a parametrically-defined surface, the wire of frame a tube spiraling vertically
Whipped up a nice parametric plot (complete with grid curves) for a fun surface in @desmos.com.

Happy to find so many familiar faces here, along with plenty of new ones. While I figure out the lay of the land, let me drop a few posts from the old microblogging site, because this is looking a little sad:
