It sure is! 🤩

It has been the honor of my life to serve as Commissioner of BLS alongside the many dedicated civil servants tasked with measuring a vast and dynamic economy. It is vital and important work and I thank them for their service to this nation.

Who's the better mathematician? Euler or Gauss? Only Kaia can decide:

Yes, at first, and then I would go with my mom/parents shopping.

Mathsci-comm Network The Mathsci-comm network brings together people who communicate, or have a stake in communicating, complex mathematics and data science to a variety of non-expert audiences.

Are you someone who communicates complex #mathematics to non-expert audiences? Then check out the Mathsci-comm network, which we've set up with support from the Newton Gateway and the Newton Institute in Cambridge mathsci-comm.maths.org

Hi! I am! :)

Yes I was, and no, definitely no.

The artichoke that COULD.

HELP ME fund math! Tag your favorite brand in the comments and tell them that it would be an awesome idea to help fund a math program! For the good of STEM, for the progress of science and math, and f... TikTok video by Álvaro Lozano-Robledo

Here is crazy idea... Would private brands sponsor a math summer school? For some brands, it would be a marketing no brainer... for $60K you can earn the good will of the entire math community!? And help make progress in STEM in the USA??!

I am so sorry Christelle :(((

Congrats!!

I live in constant fear that they will make my coffee iced by mistake.

This is great. I would love to hear more strategies to get the word/cry out!

Absolutely! Here at the University of Washington, our academic worker union is hosting a town hall with our congressperson next month to demand an end to cuts to NSF & NIH. Would be great to hear that folks at other schools are doing the same.

Math Is Quietly in Crisis over NSF Funding Cuts A 72 percent reduction in federal funding is devastating to math research. The American Mathematical Society is offering $1 million in backstop grants—but it’s likely not enough

Here is the Scientific American piece:

Can U.S. Math Research Survive NSF Funding Cuts? | Scientific American www.scientificamerican.com/article/can-...

Scientific American thinks mathematicians are being quiet about the devastating NSF funds to our field. We need to be LOUDER.

I am hearing now that it is Sunday. I am hearing this just now for the first time. Please conduct yourself to the #MathCoffeeSelfie thread below.

What kind of questions do you have?

Age verification? 5 1/4 floppy disks.

"Topology is a dense forest of counterexamples. A usable map of the forest is a fine thing.

Steven Clontz speaks about pi-Base at ICERM.

I met @clontz.org and got to hear him speak about the very cool project pi-Base!

If you know of advanced undergrads or junior grad students interested in number theory, please pass info about PAWS along to them and encourage them to participate!

Representations of two elliptic curves, y^2=x^3+x+1 mod5 & y^2=x^3+3 mod7 respectively. The first curve is represented as points on a swirly torus, with 3 pictures. The leftmost one is over F125 (the finite field of 125 elements), the middle is over F625, and rightmost is over F3125. As we move left from right each swirly torus becomes more dense with points, which makes sense given that our finite fields become larger as we move left to right. The second curve is represented as a kind of twisted torus with 3 bumps. As above we have first the curve over F343, then over F2041 and then finally over F16807. There is no ridging here so the points look more lattice like sitting on this surface as opposed to above. That being said the first curve points are similarly lattice like, but the ridging breaks it visually. From the same paper as the above post

Get in, we’re visualizing elliptic curves over finite fields

I'm not speaking but I'll be there and @clontz.org talk was in my radar!
