This 1000% more true today in there era of "Just throw it into an AI/ML black box and use the answer" than in 1979. #programming #ethics georgestocker.com/2022/05/24/w…

So many bad takes in this article. Yes, students are tired, yes they are burnt out, yes their mental health and, consequently, their learning is suffering. But to lay the blame at the feet of online learning is false. Students didn't do poorly because of online learning (and what occurred over the past 2 years is not online learning but emergency remote learning - there is a huge difference). Perhaps they have been struggling to do well because, oh idk, GLOBAL PANDEMIC? https://www.nytimes.com/2022/05/13/opinion/college-university-remote-pandemic.html

What we call mathematics https://aperiodical.com/2022/05/what-we-call-mathematics/

Some thoughts about the subject we call mathematics and how that does - and doesn't - change.

@SylviaFysica there's a pair of papers by Joe Halpern and Francis Chu called "Great Expectations" parts 1 and 2. Part 2 has a pub date 4 years before part 1.

Found this quote from Quine on van Benthem’s Manual of Intensional Logic. I’ve been reading quite a lot no modal logic, so most authors don’t agree with Quine (essentially, some things are necessarily P have two readings: \(\forall x.\Box P(x)\) or \(\Box \forall x.P(x)\), that is, ‘de re’ or ‘de dicto’). I really need to take some time to read Quine’s texts.

@erou Sometimes when you can't solve a problem it's worth going back to the definitions.

Then:

* State the definition;

* Give me three simple examples;

* Give me two simple non-examples.

/etc/.

And yes, people ignore this advice.

(Young) Math students of the world, when you don't have any idea of how to solve a problem, you can try to:

- make a drawing in order to better understand what's happening

- try to solve a simpler instance of the problem in order to see if what you are trying to prove is indeed true, why, and what could possibly be wrong in the complicated case

These are very easy advises that essentially nobody follows 🙄

Every Salami has two ends

Article by Bobo Hua and Florentin Münch

In collections: Attention-grabbing titles, Food

A salami is a connected, locally finite, weighted graph with non-negative Ollivier Ricci curvature and at least two ends of infinite volume. We show that every salami has exactly two ends and no vertices with positive curvature. We moreover show that every salami is recurrent and admits...

Logic at Tohoku University.

Mainly interested in games, modal logic and reverse mathematics.

By games I mean both mathematical ones and computer ones.
