#AcademicFreedom erosion “is part of broader democratic backslide that we’re seeing in US” says Jennifer Jones at UCS. I’ve witnessed this demise at my own college especially since the pandemic. Faculty are decreasingly supported as content creation experts. www.chemistryworld.com/news/academi...

Academic freedom slides globally, as it takes a nosedive in the US

The last decade has seen institutional autonomy curbed in 50 countries

Fun hands-on maths project to try at home in celebration of the beginning of spring term. Even if you've played with #MobiusStrip before, you can always find a new "What if?" Q to explore.

In topology today, I had the students cut Möbius bands in various ways (an activity fun for kindergarteners to college seniors). I was teaching topology when COVID hit in spring 2020. I made this Möbius band-cutting video for students who were at home.

Happy 2026 to all, especially my new Winter Term Calculus and Algebra students! findthefactors.com/2025/12/31/2...

2026 Math Facts and Factors

In this blog post, I’m sharing as many math facts about the number 2026 as I can find on my own or shared by others on Bluesky. I’m publishing the post before the year ends, but I will …

Also pre-order books from your favourite authors! Bookstores use total number of pre-orders as a metric for how many copies to order. The more pre-orders, the higher expectation for a run on purchases early after release, so will stock extra copies and promote prominently.

Will also note that if you like someone's books and want them to keep writing, supporting them by buying their books or ordering them from the library if buying isn't an option, and encouraging others to do the same, has a HUGE impact. Relatively small differences in sales numbers are make or break.

Happy #Fibonacci Day! Nov 23rd (11.23) begins the Fibonacci Sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... which is used in computing, stock trading, and architecture and design. Nature is full of Fibonacci patterns, from DNA to hurricanes, much more! www.smithsonianmag.com/science-natu...

The Fibonacci Sequence Is Everywhere—Even the Troubled Stock Market

The curious set of numbers shows up in nature and also in human activities.

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪 Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students. I wrote this little profile to mark the 100th anniversary of her thesis:

How a Harvard maverick forever changed our concept of the stars

At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

Wait a minute. Why aren't we celebrating the hundredth anniversary of Cecilia Payne-Gaposchkin's dissertation.

Topology and geometry can solve many of life’s woes. Here Dr. Roland Fryer, Professor of economics at Harvard University and NY Times Contributor, shares simple transparent process that uses #geometry to solve our #gerrymandering problem. www.nytimes.com/2025/08/12/o...

We’re celebrating Pi Day with Dr. @stevenstrogatz.com, who joins us to discuss how the ratio was "discovered" and its role in recent science.

Pi, Anyone? A Celebration Of Math And What’s New

Mathematician Dr. Steven Strogatz breaks down the history of the math concept and brings it full circle to recent science.

Happy #PiDay! Pretty cool to have a blood moon total lunar eclipse overnight as we entered Pi Day 2025. Plenty of circles and spheres to celebrate on this last day of winter quarter classes. Cheers!

Having fun playing with my new wooden soma cube. Don't know why I didn't know this before, but it can be rearranged from 3x3x3 to 4x4x2 minus 5 contiguous unit cubes that form the shape of a pentomino (1 deep). 11 of the pentominos work (of the 12). Way cool! www.youtube.com/watch?v=dGSH...

Hey new fall term students! Please read my "Why should college students study mathematics? Here are eight reasons. At least one will strike true for you." www.integreat.education/OL/docs/WhyS...

15 +/- yrs at the bird site, past year at mastodon (@InteGreat@mathstodon.xyz). Checking BlueSky out! Bit concerned just another billionaire-run corporate SM, we'll see. To stay must support ALT descriptions, ability to edit posts, have interesting #mathematics content, and plenty of kind people.
