Interesting Quanta article explaining the "universal covering problem", aka finding the smallest convex region that can cover an entire set of shapes; even restricting to shapes of "diameter 1" still leaves a tough unsolved problem in

Over on that other microblogging platform, John Baez points out how easy it is for mathematical physics crackpottery to get published in a prestigious-sounding pay-to-publish journal from an actually-prestigious publisher, Nature Scientific Reports:

In the ensuing discussion, Flavio Nogueira reports that editors rejected papers only to see them published anyway:

Should we start treating Nature as a predatory publisher?

Mahatma Gandhi, as you know, walked barefoot most of the time, which produced an impressive set of calluses on his feet.
He also ate very little, which made him rather frail and with his odd diet, he suffered from bad breath.
This made him a super calloused fragile mystic hexed by halitosis.

@Breakfastisready The trailer makes it look intriguing. And the fact that the Kindle version won't be released for a few more days is making me think it would be worth the wait to go for paper instead.

Reading this fantastic graphic novel called "Prime Suspects". It's all about analytic number theory in metaphors.

It has amazing one-liners like:

Today my advisor said:

Reading mathematics is like obesity. If you read too much, then it will only confuse you and will be harmful.

I guess I'm going to sulk about Indian politics for five more years. All my favorite candidates lost and I have a complete dislike for this re-elected ruling party. *sigh*

Okay, so it seems that the overwhelming majority feels that these jokes are sexist. But is there no way there could be a non-sexist version of these jokes?

I want opinion on this.

Are "that's what she said" jokes sexist? They could surely be perverted/vulgar/NSFW, but are they sexist?

Just want a fair assessment.

G2 shall be my favorite group! Well, for now. For a while. Or maybe for longer. It's the smallest of the exceptional Lie groups. Found 1893 by Élie Cartan. It was he who suggested to think about it in terms of rolling balls.

Picture two spheres, one three times larger than the other. Imagine them rolling on another without slipping nor twisting. Rolling surfaces have their own branch of mathematics: contact geometry!
