Hi, I’m a sighted alt text user! Here are some reasons I use it: - Slow Internet on an airplane - I’m over 40, I have no idea who that celebrity is - Bluesky broke images again - My vision sucks and that text is too small to read otherwise - Conveys further context and authorial intent
Here’s a simple demo of a 2D linear classifier in @desmos.com, using a pseudo-inverse matrix. I used to need NumPy for this. Now, with the new matrix features, it works in Desmos. Much better for being able to drag the points around! www.desmos.com/calculator/6... #iTeachMath
Excited to share that some of my research on how students recognize each other in physics and how that fits with their physics identity was just published! #iTeachPhysics onlinelibrary.wiley.com/doi/10.1002/...

Not just cubes, either. This abuses the heck out of rotations, and since it now happens by multiplication instead of having to pass it as a parameter, it makes the notation a lot easier. #Desmos www.desmos.com/calculator/v...

A fun fact about neutrinos is that they come in three “flavors” (types) and also in three masses and you would think that this means each flavor has its own mass and you would be absolutely wrong about that.
And here’s the timelapse with the Dwarf Mini
Wow, I love this graph. I made it faster by taking some of the implicit plots (which have to sample over the entire 2d space) and instead sampling the endpoints and connecting them with parametrics: www.desmos.com/calculator/m...

Sen. Susan Collins helped steer millions in federal defense contracts to Navatek, whose CEO illegally funneled thousands of dollars to her campaign. The FBI sought to launch a probe and was eyeing Collins and other lawmakers. Then Trump gutted the unit in charge. THREAD 🧵

I downloaded an app that’s supposed to pick up words that ghosts are saying near you. I tried it out at the local coffeeshop and it took a real turn.
Every now and then I see myself referred to as an "AI Denier" and I want to be clear I acknowledge "AI" exists, it's just I think it's a massive energy drain, created from theft, implemented poorly for inappropriate tasks by loathsome tech executives who get hard at the idea of the rest of us dying
They are trying to blame AI for these kinds of mistakes in the way that you put googly eyes on a rock and then pretend it's a scapegoat.
Suppose you take k points in the interval [0,2π] (spaced apart by 2π/k) and map them to the rose curve r = cos nθ. Then you can get interesting looking graphs - and sometimes, a regular polygon. (Thanks to @helsig.bsky.social for the idea.) www.desmos.com/calculator/g... #iTeachMath @desmos.com
