The European Women in Maths released a poster featuring Notable Women of Mathematics and short biographies.

It is free to download and print in Dutch and English (for now, more translations are ongoing as far as I know), it would be great to display it on the walls our mathematics departments: https://www.ewmnetherlands.nl/projects/women-in-mathematics-poster/

A brief article on a brief proof. I'll be interested to see how well mathematicians that aren't topologists can grok the concepts described here.

A version of a figure from almost exactly four years ago (version 7 apparently), and the hopefully near finished version (version 31) from earlier today, with @saulsch. #WhatMyResearchLooksLikeRightNow

I sort of disagree with. I think that being a mathematician helps a lot (because I already think in terms of definitions, lemmas, and so on).

2. https://news.ycombinator.com/item?id=18255414

suggests that the checker just computes to high precision, or perhaps computes "the function" at several test points (every construction can be recast as a function).

which I've not read yet.

RE @KangarooPhysics @robinhouston: Also, looks like you don't even need that restriction on the dimensions

@ColinTheMathmo @nilesjohnson I invited @saulsch using an invite link a couple of days ago and it seemed to go through quickly.

@neilbickford Hmm. Actually this is a concern: if two parts are identical (like the ball bearings here), then the puzzle cannot mechanically tell them apart. This introduces symmetries in the configuration space, and so reduces its size (?).

Oskar van Deventer has a new mechanical puzzle that requires 4^55 moves to solve: https://twistypuzzles.com/forum/viewtopic.php?t=37692

So, he's got a system that produces a puzzle whose solution length grows exponentially in the number of parts.

Question: Is it possible to come up with a system whose solution lengths are super-exponential in the number of parts?

Nobody quite knows how it works, but occasionally people will wake up to find they have been given a Gift, a special ability like Healer, or Invulnerable, or Prophetic. And somehow everyone knows about their new Gift.

You woke this morning knowing you are a Bestower of Gifts.

Katie Steckles and I have a podcast called Mathematical Objects, which releases a short chat on a mathematical topic fortnightly in seasons of 8 episodes.

Today's episode is "A joke" with special guest Bec Hill. We talk about similarities and differences between maths and jokes.

Hopefully you can find it where you normally find podcasts (let me know if not!) or listen/subscribe/etc. via https://aperiodical.com/2022/05/mathematical-objects-a-joke-with-bec-hill/

A mathematician. Interested in low-dimensional topology, geometric group theory, and computational aspects of those areas.
