Quick evening thread on the 2022 #NobelPrize in physics 1/n Image Let's assume the universe is somewhat rational and behaves in a way you would expect. Not hard, right?

You would expect that things don't have spooky action at a distance. You would expect things only to influence things close to them. 2/n

RADIKALA SEMLOR: EN TRÅD

En bekant har i snart tio års tid bakat (och ätit!) fantastiska semlor. Jag tycker de förtjänar större publik och delar (med tillstånd) hans kreationer här på twitter.

Känsliga semmelpurister varnas!

Först ut är en #semla gjord på apelsin: Kanelbullesemlan har ni nog hört talas om innan, men denna postades av min kompis på FB långt innan hipster-cafeer fick idén. Coincidence? I think not!

Very nice write-up on the lack of collision resistance in the Curl hash function previously used by the #IOTA cryptocurrency. Includes source code for generating collisions, formal proofs, and will be the final say in this debate. github.com/colavitam/curl… The paper is due to Michael Colavita and Garrett Tanzer, both of Harvard University. It appears to be original research performed independently of the paper by Heilman et al. Big thanks to @cybergibbons for bringing this to my attention.
