This is the moment Twitter category theorists have been waiting for.

Going forward, any space obtained by taking the smash product of another space with a circle will be permanently suspended

Spotted in Santorini: some kind of weird tensor product between a mapping class group and a special unitary group?

On my 25th birthday at Santorini airport, can’t believe I had to make the cutoff for the 25-65 button 🥴🥴

Don’t know how I missed Loviet February album but now gotta figure out if I should see her at FEQ or Bluesfest 🤔

Toronto has the largest Deep Lake Water Cooling system in the world. But what is it, and how does it work? Here’s Rebecca Gao with a full breakdown on the system, the buildings attached to it, and the coming expansion. torontoverse.com/articles/3dF--…

Hold on to that feeling 🎶

🤹‍♂️I realized something cool about the three ball regular juggling pattern. You can see it as borromean rings. Let me explain this #MathGIF ⤵ 🧶1/n

Symplectic geometry starts with a "closed, non-degenerate two form", and turns that into its whole personality. But what does symplectic taste like? IMO, one of these nerd clusters. Crunchy tangy nerds w/ a gummy center. Here's how symplectic's flavor changed over the years 1/🧵

Can't wait to show up to the seminar dressed like this

In contact geometry, the structure of high-dimensional spheres can lend insight into physics and an infinite host of related manifolds. In a new paper, four mathematicians have discovered a new type of contact sphere. @slomanleila reports: quantamagazine.org/in-the-wild-we…

What's going on here? No, it's not AI. Math-art-matician Shiying Dong, who published a paper on her topological crochet in the Bridges Conference, has the answer — and she is once again offering online classes with MoMath. Visit momath.org/crochet; limited space available.

It’s been a sec but

We go to Target and Trader Joe’s and then head home

If you shift any input 𝑥 to -𝑥 in a function, then 𝑥² outputs the same value. Infinitely many functions satisfy this symmetry. Here are just a few: quantamagazine.org/behold-modular…
