I've never posted a cat photo. Let this be my first! Here's the Cat's Eye galaxy. An intermediate spiral galaxy currently being sculpted, hence the ghostly outer region. Image credit: ~8hrs on my tiny smart telescope #science #astronomy 👩🔬🔭 #catsky #caturday
So ........ what would YOU like to know about Neutron Stars? There's no such thing as a silly question, because neutron stars are .... well, silly objects that break brains! Tell us and we can see if we can collate articles, infographics, field specialists, historical context, or more! #NSWeek
CosmicRami 🏳️🌈🏳️⚧️@rami.spaceaustralia.com · 2w agoYou've probably heard of Black Hole Week, BUT did you know there is ALSO ...... NEUTRON STAR WEEK! Next week is the anniversary of the excellent event GW170817 and @astronerdika.bsky.social and I think the neutron stars, pulsars, magnetars, etc. need their own week! #NSWeek: Aug 16-22 📸 NASA SVS
On the right is Stephan's Quintet of galaxies. On the left is NGC 7331. And flagged for violating Hubble's Law is NGC 7343, the bright dot at the bottom center. 8 measurements have shown the galaxy to be much closer than expected. Image credit: 19 hrs on my tiny telescope 👩🔬🔭
Gauss noticed something strange about quadratic forms in 1801 -- a repeating pattern that sat unexplained for 200 years. Here's the story of how 2 mathematicians used just about every branch of math to finally understand it. www.scientificamerican.com/article/math... #science #math 👩🔬
Mathematicians make a breakthrough on Gauss’s riddle, unsolved for 200 years
A solution to part of the Cohen-Lenstra conjecture helps resolve a long-standing mystery about quadratic forms

Sums of squares have fascinated mathematicians for centuries -- especially because of their strange ties to the prime numbers. Gauss wanted to study them more broadly. Here are the end-notes for my latest in Scientific American - the fascinating bits that didn't make it into the article: 1/

I interviewed 99-year old Joan Birman who must be the oldest author on a major breakthrough paper. As an added bonus: her team beat the guys trying to use AI! Please read and share about this human triumph: www.scientificamerican.com/article/how-... #science #math 👩🔬
How a 99-year-old mathematician unraveled a century-old braid mystery
Joan Birman popularized the Burau representation problem decades ago. Now she and two colleagues have a proof that reveals brand new insights into the geometry of braids

I had a surprising conversation. A NASA engineer told me he was stuck at home early in the pandemic when his power went out and he couldn't find batteries for his calculator. So he used his slide rule. For one whole evening. Power was restored the next morning.

Google photos auto-created an album of "photos of me" over the years.... and included this particular one 😂 Fortunately, my Lego doppelganger is incapable of implicating me in any real-world mischief!
Happy π Day! To prep, feast on this article on a brand new discovery for the ancient constant. My latest slice for SciAm! It's irrationally enjoyable... 🥧 www.scientificamerican.com/article/math... #math #science #PiDay 🔭👩🏾🔬
Mathematicians find one pi formula to rule them all
A mixture of AI and algorithms uncovered a hidden structure spanning 2,000 years of equations for pi

For #WomensHistoryMonth: Let us celebrate the life and accomplishments of French mathematician and physicist Émilie du Châtelet (1706-1749). She spread the then-new ideas of Isaac Newton on the Continent, and played a key role in developing the idea of energy conservation. 🎢⚛️🧪 #WomenInSTEM 🧵1/7

My grandfather fixed radios on the Black side of town. White-owned repair shops also brought him radios they couldn't fix. He made enough money to open a few grocery stores as a "retirement business".

I just realized that today is Chinese New Year, the 1st day of Ramadan, AND Fat Tuesday. That means the Chinese new moon lined up with the Ramadan crescent and also fell exactly the right amount of time before the Easter full moon. An extremely rare lineup of 3 major moon-based traditions!
