Wow, that output looks amazing! What typesetting system are you using?? 😁

This sudoku is full of #math lessons: logic, combinatorics, symmetry, and joy. Try it here: sudokupad.app/qt0xjevecl. Then watch this: youtu.be/ddnLr8jWNeY?...

Zero dates back to the early days of Wimbledon, when a homophobic sportscaster was uncomfortable declaring the score Love-Love

The better question, "if you are not able to stop the flow of asylum seekers, do you think the US has enough insane asylums to hold all of them?"

This is a great question. For me, it means I see how I could teach the concept. I can see the whole story arc of how the mystery fits together.

Clearly they knew you wanted to decorate with purple roots. That's what you get for grocery shopping at Hobby Lobby

I tried to capture some of the advice from a seminar by an accessibility expert as part of the PreTeXt guide. See Subsection 4.40.3: Advice for Writing Image Descriptions

The easiest way to use pandoc for pretext is to use the feature in vs code and pretext-tools. Assuming you have pandoc installed, search for the command pretext: convert file to pretext.

There are currently too many conversions in pretext-tools. I need to clean that up.

if you click the first hyperlinked word on any wikipedia article, and then click the first hyperlinked word on the next one, and so on, within 10-15 clicks you will get to the wikipedia article for philosophy. and i think that's beautiful

Mathematician solves algebra's oldest problem All you need to do is toss out irrational numbers.

And yet, the recent piece circulating from popular science includes, "“[I don’t] believe in irrational numbers,” he said."

Are we sure we aren't living in Fight Club? Or am I not supposed to talk about that?

I hear, "Happy Easter to those who celebrate it. And to everyone else, enjoy celebrating Hitler's birthday."

I wonder why the Democrats aren't trying to change his mind more, given how easy it is to do. Seems like with the right level of flattery and cleavage, he could be leading the Democratic party by now.

This is a good point. I keep forgetting about this as an option. I'll try to add it to my post.

My post about accessible math and other STEM materials is now up: mathtech.org/2025/04/10/a...

After waffling for years, I finally tried mastery based grading for the first time. Wow, what have I been wasting my life doing before now?? It finally consistently felt like my students and I were working together to all understand the hard stuff together.

Dry doing that, ai.

Is the idea that parts of your typed notes will be replaced with whitespace for a printed version? How much whitespace?

I think this is a great idea, but isn't possible right now unless you write the notes as worksheets, which is the only way to get "workspace" currently.

I've used it for quite a while for notes, todos, and almost everything productivity related. Love it. But to use it for tasks, you need to make sure you have a system to remind yourself to look at it; I don't know of any notification stuff you could do.

IPEVO V4K Ultra High Definition 8MP USB Document Camera — Mac OS, Windows, Chromebook Compatible for Live Demo, Web Conferencing, Distance Learning, Remote Teaching V4K Ultra High Definition USB Document Camera is your premier presentation tool – its 8MP camera allows you to capture ultra high definition live images up to 3264 x 2448; its high frame rate at high resolution helps deliver stunning silky-smooth live streaming without latency; its fast focusing speed minimizes interruptions when you’re showing and comparing different materials; its excellent noise reduction and color reproduction by Sony CMOS image sensor makes it perfect for capturing in dimly lit environments; its newly designed multi-jointed stand offers both versatility and a simple fix for tightening loose joints caused by heavy daily use.

I have used and liked this one: amzn.to/4lkxO96. But there seems to be many cheaper ones now.

All statements made by me in posts on bluesky today are false.

I wish Discrete Math was taught in high school. It was one of my favorite classes. Esp binary relations changed the way I thought about the world. Even now I have a habit of turning irl things into binary relations and thinking about if they're symmetric, antisymmetric, transitive, reflexive +more😅

My SIMIODE EXPO 2025 talk on why #PreTeXt is so awesome, even for creating small course materials, is now up. You can find it through this MathTech.org post:

Two examples: 5 years ago I became chair of faculty Senate, which meant almost no teaching but instead being the lone faculty voice to the upper admin. Then this year I'm on sabbatical spending all my time developing PreTeXt features. Always wanted to do programming; I get to roleplay for a year.

Does this work?? Having a vault of pictures sounds like a great idea.
