Really charming "topologists world map."

Forget size or position, this map *only* shows which countries border which other countries: http://tafc.space/qna/the-topologists-world-map/

For the past 3+ years, I've been chairing an all-star National Academies committee charged with creating a series of posters on Illustrating the Impact of Mathematics. The website is finally live, and I'm really excited to share the results!! 💃 Please share!!

Interesting thought experiment:

What does it take to succeed in your math course - in terms of prior content, mindset, perspective on math (as more than computation), work ethic, attitude toward working with others, etc.

Why do our systems limit prereq discussions to prior courses, or worse, placement tests?

On Martin Davis:

https://dailycal.org/2023/01/08/warm-kind-intellectually-brilliant-mathematician-martin-davis-dies-at-94 by George Bergman

(On a comment in FB, Ken McAloon mentioned that "after retirement he spent lots of time at Berkeley, which he described as `heaven with a library'.")

On Martin and Virginia Davis:

https://www.digitalfieldguide.com/blog/20341 by their son Harold.

Stephen Hawking was born #OTD in 1942. He developed theorems with Penrose that determine when general relativity produces singularities, established classical laws of black hole mechanics, and hypothesized that quantum effects make black holes radiate.

My PhD supervisor Yuri Manin passed away yesterday.

He was one of the most influential mathematicians of the last 60 years. But for me, he was simultaneously my diploma and PhD supervisor, one of the kindest persons I have ever met, and one of the most intellectually curious.

Today in 1983, 40 years ago: The ARPANET officially changes to using TCP/IP, the Internet Protocol, effectively creating the Internet.

Everything you always wanted to know about QCD? At any rate, an extraordinary document.

This is an official account of the Simons Laufer Mathematical Sciences Institute (SLMath) in Berkeley, California, formerly known as the Mathematical Sciences Research Institute (MSRI). Expect more activity from us in the new semester but in the meanwhile, you can find our latest news at https://mailchi.mp/msri/emissary-newsletter-fall-2022-slmath-upcoming-events. #Introduction

It's not just journalists! Even the director of the Institute for Advanced Studies was hoodwinked by scientists claiming they had created a wormhole, Scott Aaronson reports:

For how these scientists managed to avoid scrutiny - getting their story into the media before anyone who really knows physics could swat it down - read this:

Hello #Astrodon

I'm a gravitational-wave astronomer researching the formation and evolution of black holes and neutron stars

I primarily work on LIGO–Virgo–KAGRA data analysis, inferring source properties, but I'm also interested in space-based observatories like LISA

I enjoy #SciComm (I want to get back into blogging https://cplberry.com/blog/), and I'm currently a member of the community-science Gravity Spy project https://gravityspy.org/

I also like cake

The Koide formula is a mysterious relation between the 3 charged leptons:

the electron,

the muon (like an electron but ~206.768 times heavier),

the tau (like an electron but ~3477 times heavier).

Nobody knows whether it's really true or just a coincidence.

For the most part, serious physicists have given up seeking relations between masses of elementary particles, because it's so hard to *explain* any such relations.
