Oh yeah, I got it to say I was correct there, but couldn’t figure out how to make the animation match

My understanding is that you are supposed to land on the goal line exactly, and use the initial conditions to find the range. It just seems really hard to do.

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 🧵

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

Panel 2: he is now doing work on his computer. Looks like he completed some drawings. He continues “..is my best”
Panel 3: he is now making some food in the kitchen, wielding a pan and wearing a tiny chefs hat. He continues talking to himself “..and my best..”

tried to explain to someone why openai's actions are so serious. not to be dramatic but we are in hell and all the demons are here

there are tons of issues here. almost impossible to convey how bad things are. in no particular order:

this research breakthrough was a consequence of dumping tons of money into the ai companies. if the future of the field means being entangled with openai et al. and extreme expenses that is going to upend mathematics in a much bigger way than ability to prove new things will. this hasn’t been a focal point of discussion yet but it looks to be at the center of mathematics going forward imo.

possibly for legal reasons, the statement stops short of accusing openai of stealing their in progress work. as in literally snaking their documents off the cloud and using them to try to undercut researchers. but it’s very clear that that is what the author believes happened

openai straight up threatened the mathematician in question. in a colloquial sense they’re engaging in extortion. apparently this is so routine for them that they didn’t even stop to consider that they can’t threaten an academic’s career (or they assumed the mathematician would understand there will be no academic careers in the future)

openai is straight up lying about their research methods. there are various ways that their announcements have had the potential to be misleading (for example when you see “we spent $2000 to compute these proofs” ask how much they spent on attempts that didn’t work). but what they’re saying may generally just not be true even in a literal sense

What route should you take from the blue pin to the red pin, if you need to cross the road to touch the far side in between? You want the fastest route, but counting time on the road for double that on the pavement - it is more dangerous. you will rediscover the laws for reflection and refraction!

In 1966, Mark Kac famously asked "Can you hear the shape of a drum?" In most cases you *can* hear the differences between two drum shapes. But in 1992, Gordon, Webb, and Wolpert constructed isospectral sets of drums: different shapes that nevertheless sound identical. 🧪 ⚛️

I am thinking about having my students (~35) design their own impossible objects this semester. That would mean I would have to print quite a few of these. This little guy took about 27 minutes, and it is pretty sturdy. If I put multiple on the build plate, this might be reasonable.

So we know AI helped a negligible number of students. But how many did it harm? I've crunched the raw data provided by the lead researcher, and what I've found is that ~9,500 students using AI studied less than even the *least* studious, non-AI using student. This should shock the conscience.
