Wow, that's a lot of pennies.

One dollar is equivalent to 35 pennies.

@lowqualityfacts Making change has always been difficult for me. I’d hand over a dollar and ask for 8.818 ounces of pennies. But that’s only want to give me 0.8 ounces of quarters. That screws me out of a whole 8.018 ounces of metal.

Happy birthday to & geodesist Gladys West (née Brown 1930)! Shown with 3 satellites important to her career + tracks: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. She started her career at 🧵

I didn't understand much of it - and still found this animation amazing².

cant believe i have to share a democracy with people who are wrong. seems like a design flaw. who approved this

@Daojoan The people who ‘approved’ it, are the people who voted for public ‘leaders’
that shifted focus away from teaching language and critical thinking skills to ‘feel good’ priorities, such as stadiums costing in excess of $70 million, all while standardized test scores in , and for students in the have been falling for decades! 🤔

There’s a ‘good’ reason Trump said “I love the poorly educated!”

🤥 Leading OpenAI researcher announced a GPT-5 math breakthrough that never happened

｢ Mathematician Thomas Bloom, who runs erdosproblems com, pushed back right away. He called the statements "a dramatic misinterpretation," clarifying that "open" on his site just means he personally doesn't know the solution - not that the problem is actually unsolved. GPT-5 had only surfaced existing research that Bloom had missed ｣

Wait, does this mean we could get rid of quaternions? https://www.zmescience.com/science/news-science/mathematicians-just-found-a-hidden-reset-button-that-can-undo-any-rotation/

Mathematicians Just Found a Hidden ‘Reset Button’ That Can Undo Any Rotation A simple scaling trick can rewind even the most tangled motion back to its start.

@djlink That sounds like an interesting idea, but the article doesn't make sense.

If I rotate first by 20 degrees and then twice by 2 degrees, I am, in fact, not at 0 but at 24 degrees.

maybe someone from the sphere can shine more light on how it works?
