Characterizing finely the decay of eigenvalues of kernel matrices: many people need it, but explicit references are hard to find. This blog post reviews amazing asymptotic results from Harold Widom (1963!) and proposes new non-asymptotic bounds.

Thank you, Lawrence
I enjoy how you call balls and strikes. We need your widom these next 4 years.

This is older than some children who can do math, but still a favorite! I made an animated magic circle to symbolize the Tracy-Widom distribution’s universality — #SciArt for an article by my friend Natalie, for Quanta mag: www.olenashmahalo.com/project/trac...

I’m always opening up a cook book thinking it’ll give me secret widom to complete a simple recipe from dry pantry items and raw meats and then it tells me to open up a can and insert pre-cooked meat item

This is really sad news! Ben Widom was a brilliant scientist and teacher as well as a wonderful human being.

The big problem facing America is that the accumulated Widom of Senior Citizens is neither acknowledged nor Validated in this Society.

A once local artist, Diane Widom drew this of a place known as the Dryden mansion.
It must have been nice in its original form, but def time took it's toll.
I had good friends living here and spent many fun evenings around the wood stove 😊🌹

I'm dipping in and out of Echoes of Widom every couple of weeks, but it definitely feels like it's getting more fun now. I've completed the 2nd dungeon, and the new skills and echoes I'm learning really make it feel like the world is opening up a lot more 🗡
