Do you handle graph-based problems and are interested in a
new and innovative approach to solving such problems?

From Wednesday to Friday this week, the Kick-Off event of the junior research group GAIN- Graphs in Artificial Intelligence and Neural Networks will take place.

Talkers included: Matthias Gebhardt, Marián Boguñá, Michael Bronstein, Martin Braun, Alexander Scheidler and Daniel Martinez.

I have written a program that turns strings of hex digits into lists of allowable 2-letter word prefixes such that the total frequency of all the words starting with the prefixes corresponding to each digit (0-f) are approximately the same.

The idea is to reversibly turn any hex string into prose or poetry. The decode process does a reverse mapping on the prefix of each word of 3 or more letters (other than "the", I might add "and" too). This lets you add filler words to make the output flow.

"Our ship must seem primitive to you who have been spacefaring for millennia."
"Not at all," the Frinx ambassador said, "we find it very clever. Especially that reality evacuation facility. We have not seen anything like that before."
"Reality evac- Oh! You mean the library?"

Seeing someone reading a book I like, it's almost like the book is recommending the person.

Good morning! My name is Colin and I’m a mathematician. What can I help you with this week?

(Here is a round-up of the kind of help I can offer: )

I'm just surprised, as I'm pretty sure without recursive types or values it is impossible to define fix, but I didn't know recursive types could help.

You, a tech startup with millions in angel finance: made an app to turn handwritten maths into TeX.

Me, just the worst kind of smart alec: convinced a pen to turn TeX into handwritten maths

mutual support idea 

advanced googling of emotionally difficult topics as-a-trade-service because so many of us find it fun and easy to figure out paperwork bs when it's not our own paperwork (or locating doctors, or figuring out what funding programs exist), but scary impossible when it's our own - we could leverage this emotion vs. action disconnect as the super power that it is when it aligns well, instead of just the agony of mis-alignment.

very few of my devices and projects are actually named... this feels like a major failure to anthropomorphise

I'm giving a talk!

It's free, and aimed at a general audience interested in mathsy things.

Register here:

Date is Feb 3rd, time is 5pm EST and Panama time, 10pm UK time, 9am in Victoria and NSW Australia.

Questions welcome!

I'd be grateful if people would re-toot this to get outside my bubble ... thank you.

Why just invert colors when you can also blow your entire screen to night-time monochrome?

You know, that quote, by Sofya :kovalevskaya: "It is impossible to be a mathematician without being a poet in soul." ?

I was wondering why it sounds so much like Weierstrass's own quip, "It is true that a mathematician who is not somewhat of a poet, will never be a perfect mathematician."

That's because she is paraphrasing her collaborator in a letter to Madame Schabelskoy. I prefer Kovalevskaya's version.

Here is an excerpt from a memoir/biography of hers:
