The Longest Matrilineal Chain in Math: blogs.scientificamerican.com/r

Evelyn Lamb finds "five advisor-advisee chains of length four containing only women" in the Mathematics Genealogy Project, all starting with Olga Ladyzhenskaya and her student Nina Ivochkina. But her searches were haphazard so there may be longer ones still to find.

The word 'hyperboligami' popped into my head this morning and now I need to make it happen

Looks like the Taler website got updated at the annual meeting, too: https://taler.net

Looks much better already.

What do we want?

Lazy evaluation!

When do we want it?

Only when it is needed!!!!

The worst is when you're stressed about math and finally force yourself to go to bed, but you do math in your sleep all night 😞

My brain: without loss of generality

Also my brain: wuh-log

The SIGACT Committee for the Advancement of Theoretical Computer Science is planning a Wikipedia edit-a-thon, in Phoenix on June 24 as part of STOC: see thmatters.wordpress.com/2019/0

You can help, and you don't even have to brave the desert heat to do so! There's a shared spreadsheet linked from thmatters.wordpress.com/2017/0 where CATCS is crowdsourcing TCS topics on Wikipedia that need help. Add your favorite missing algorithm, theorem, complexity class, etc, and it's likely it'll get some attention.

Added an option to view the edges of the tetrahedra in our Cannon-Thurston map explorer. This should make it easier to (eventually) explain a bit how the images are generated. henryseg.github.io/Cannon-Thur

People who use the notation \((a,b)\) for the gcd of a and b: I bet you're the kind of people who take up an extra seat on the bus with your bag

A little house sits atop a rise in the middle of a wide prarie.
A rumbling, thudding sound is heard overhead: a gigantic black military helicopter, bristling with sensors and weapons, descends out of the clouds.
The helicopter drops rapidly, seeming to be about to crash, but then pulls up at the last moment and comes to a complete stop in midair, directly in front of the house.
Slowly, gingerly, it extends its in-flight refuelling probe towards the hummingbird feeder hanging from the porch.
