Hi

Scroll down for some important accessibility announcements.

The Online Encyclopedia of Integer Sequences (OEIS) is an amazing resource for professional, amateur and recreational mathematicians. If you haven't seen it before please take a look:
https://oeis.org/

It was started by Neil Sloane as a graduate student in 1965. It now has over 350,000 sequences. Around 1996 it became a website, hosted by his employer AT&T Research. In some sense this week's TeX Hour is a guide tour of OEIS and of Neil Sloane's file cabinet (digitised). And Digital Typography is defined to include Digital File Cabinets and other Research Archives.

The TeX Hour is Thursday 2 February 6:30 to 7:30pm GMT. For more information see https://texhour.github.io/2023/02/02/int-seq-and-digit-typo/.

ACCESSIBILITY NEWS

In January there was a special double length TeX Hour on STEM Access. It was so much fun that most of the 20 people there wanted to do it again. So there will be another double length meeting focussed on STEM Access, probably sometime in April. Watch this space!

And the videos from the January meeting are now available.
Talks: https://texhour.github.io/2023/01/19/stem-access-author-reader/
Discussion: https://texhour.github.io/2023/01/19/stem-access-author-reader-bonus/

On Wednesday 1 March 2:00 to 5:00pm GMT there'll be a workshop: Creating accessible online mathematics and statistics notes, hosted by Jenny Hughes and Peter Rowlett of Sheffield, UK. For details see http://talmo.uk/events.html

On Friday 10 March 10:00 to 12:30 EST there'll be an Accessible Notebooks Hackathon, hosted by the Space Telescope Science Institute - see https://iota-school.github.io/accessibility_hackathon/.

Still here? Here's a random OEIS query: https://oeis.org/search?q=3+1+4+8

wishing you happy counting and access to math and stats and space

Yes, oeis is an incredibly useful resource. I've had more than a few
occasions with an algorithm, but no closed-form expression denoting
what it represented. In such cases, you can program it, print the first
few terms, and then paste that output into oeis. Works more frequently
than you might guess. One recreational example I did (I'm "eigengrau"
on stackexchange) is my answer to
https://math.stackexchange.com/questions/4380919#4381846
which then suggested the followup question I asked at
https://mathoverflow.net/questions/416289
So oeis can lead to stuff you'd never even be able to think of
without it.
