I feel this is getting a disproportionate amount of attention on here, relative to the 369 papers that haven't been withdrawn

I didn’t even notice this one at first. This is cool! Talk about a weird machine. > 376. Universal computation in forced Navier–Stokes flows. Constructs viscous incompressible flows starting from rest on a fixed flat three-dimensional domain that perform universal computation under smooth […]

Ha ha ha, the article is 84 pages long and most of them look like this. I don't know what I expected.

It's a good thing I went to bed just before this dump dropped, or I would have been up all night

Holy ****, they solved Hilbert’s tenth problem over ℚ‽ And I'm still on the first page of the problem list.

This is not my fight, but I don’t at all relish the prospect of the criteria by which mathematicians are judged becoming subjective ones. That opens the door to so much potential corruption that it makes my heart sink to think of it.

There's an amazing new result in algorithmic complexity today. 3SUM is the problem: given a list of n numbers – there are different versions of the problem, depending on whether the numbers have to be integers or not – determine whether three of them sum to zero. There is an O(n²) algorithm […]

You can make it match up perfectly by slightly squashing the octahedra.
