Oh and I finally listed a physics ink painting! #sciart artologica.etsy.com/listing/4469...

Cover art for Discover Calculus. The background shows a plane flying over water in an arc. Reflected in the water is the plane and its arc but also diverging curves, rippling in the water. In the background is a bridge and some lights. The sky is dark with shining stars, a crescent moon, and beautiful clouds. The whole picture is a warm grey/brown with black hatch shading and white highlights. Discover Calculus Single-Variable Calculus Topics with Motivating Activities Peter Keep

It's here! @acidlich.bsky.social created this beautiful cover art, perfect as a representation of the book. While students will mostly be interacting with the book digitally, I'm very excited for the printed copies that we'll be making to give to students as well!

I like to tell students "I did not ask you to solve these differential equations because I needed them solved" and sometimes the light goes on.

I have personally decided to lean straight into losing my shit

Illustration on grayish brown paper, has a very nice texture of a plane flying above a bay as night is falling. The shape of the plane’s flight path is rather like a piece of the graph of cosine, reflected in the bay can be seen this same part of a cosine kind of shape with some graphs bouncing off of it, represented by white reflections in the surface of the water. These represent the first few approximations of cosine by Taylor polynomials. Beyond the bay can be seen some building and lights and bushes and a suspension bridge. The sky has a crescent moon and is full of stars. Hatch shaded with white accents

Exciting news, I finished a drawing!
I still actually haven’t decided on a name yet, but I might call it Taylor’s Theorem. I am however open to (good) suggestions (emphasis on good)

what this is great news 😍

"sin^2 φ is odious to me, even though Laplace made use of it; should it be feared that sin φ^2 might become ambiguous, which would... occur... at most very rarely when speaking of sin(φ^2), well then, let us write (sin φ)^2, but not sin^2 φ, which by analogy should signify sin(sin φ)" -- Gauss

brain cell check. she has none

he's right and he should say it

Let me tell you something. Y’all are asking too many damn questions at every point of sale. I have to leave a comment, make a suggestion, donate to a charity, choose a method of payment three times and then multiple choice of ways to get a receipt.

Take the damn money and leave me alone.

I need to study the history of soup immediately

International Women’s Day? On the same day they take an hour away?????

wow my kid won't leave me alone no matter what language I ask him in

right this is me vs. me for sure

Daylight is irrelevant if you have the metric system, because it measures time not in hours but by weight, using kitchen scales. That's only because the international governing bodies couldn't agree on the duration of a coffee spoon.

me, picking up my kid who has fallen asleep on the floor: well,

we should lose an hour on like. Monday during work hours

yes this too

kind of obsessed with this graphic i found on LinkedIn that makes the euler equation look like some timecube shit

NASA lost a lunar spacecraft one day after launch. A new report details what went wrong Why did a $72 million mission to study water on the moon fail so soon after launch? A new NASA report has the answer.

For when your physics students don't draw a sketch of the components before determining the direction of as vector: "Software that was supposed to point the spacecraft solar panels toward the sun instead pointed them 180 degrees away from the sun." www.npr.org/2026/02/26/n... #ITeachPhysics

Having some of the most thoroughly redacted thoughts of my life.

ok phew I was worried that all my integral domains were in danger

what if n = 0

I'm going to move to Portland so we can start a whole business

I'm saying!!

hell yeah I'm in
