Right? I'm biased of course but it was a top 5 sports moment

One thing we don't talk about enough as baseball fans is how GOOD the production values have gotten.

Watch Czechia's Ondrej Satoria leave the field to a standing ovation in Japan. The WBC production crew shoots it like a movie. You couldn't storyboard, shoot, and act this any better

The Vladdy post-game interview with Hazel in the playoffs really drove this home for me.

I voted (in-person for the first time) today! Got to vote for @robinlynnekelly.bsky.social and @robertpeters.bsky.social and it's just nice to have some decent progressives on the ballot! If you're in IL, go vote early!

I immediately read it as gendered when I saw it. You use a real picture (of you and elliptic curves, imagine thinking you needed to learn calculus) and it seemed clear that the person replying didn't know anything about you other than your gender and the specific artwork you made for the book. Gross

Yah my initial reaction is that it's the coolest professional sports team logo I've ever seen

Holy shit I wasn't ready for that logo!

You can't just say those numbers on a day like today after a past few days like the past few days, it's hurtful to those of us staying here

Isn't it great?! It seemed obvious to me to try to get @acidlich.bsky.social to do it. I've loved her art for a while and she does a great job of embedding cool math in it. I think she really nailed this one, and I can't stop smiling about it

I donโ€™t even know how to tell you this but my art is on a math book

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.

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'm hearing people describe it as the best news possible!

It's me, I'm describing it that way over and over, because it really is the best news for me!

The same drawing as above but I have changed the warm gray to warm reddish pink

It's beautiful!! Lizzie is incredible, and I'm so excited to get to use this! Anyways, commissioning art from people from #MathSky is perfect, 10/10, buy stuff from @acidlich.bsky.social.

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 planeโ€™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 havenโ€™t decided on a name yet, but I might call it Taylorโ€™s Theorem. I am however open to (good) suggestions (emphasis on good)

First day of Spring Break and I got my taxes filed! I deserve several days of not doing a single thing for overcoming this huge obstacle.

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

I've seen it around, but haven't tried it. I have a hard time getting those kinds of games, because I often feel like I'm buying a second copy of something I already have. I've heard it's really good, though!

Very nice morning trip to the Dunes. I always love these kinds of outings, where we pretty much have the place to ourselves.

Ok, disconnected my main PC from the Internet, loaded up my old unsynced save, and then reconnected to make that the steam cloud save. Lost some progress, but at least all the characters are unlocked again.

It would have been weird to leave the best American player off of the roster just because Buffalo is GTA-adjacent

Everdell set up on a table. There is a round green board with cards and tokens and symbols on it, as well as a tree standing up. In front of it are various cards. The whole thing has a very cute woodland theme.

7yo is finally learning to play Everdell. She's been asking for a while and we finally have the time.
