I’ve been remiss in my “cool stuff” posting, so let’s try to get that running again 🙂
Andy Weir’s Best Seller ‘The Martian’ Gets a Classroom-Friendly Makeover – as someone who swears A Lot, it makes me a bit sad that editing swearwords is deemed necessary; but I still find the whole concept of “wait, that book is actually usable in a classroom, except for the swearwords, let’s see if there’s a way to get an expunged version” pretty neat 🙂
Mambo mit den Schlümpfen – yes, it is Mambo Nr. 5, in German, with Smurfs. Things I didn’t know I needed in my life.
Living Proof: Stories of Resilience along the Mathematical Journey – a collection of short articles about people in math, whose path may not have been as straightforward as it could have been. This sort of things is important – it normalizes the struggle that many people go through, and I believe that it makes it less likely that some people just give up on things because “it shouldn’t be that hard, if it’s that hard I’m not meant for it”.
Sensitivity Conjecture resolved – Aaronson’s post was the first I saw, but all the theoretical CS blogs I follow talked about a very pretty paper that just arrived on ArxiV: Induced subgraphs of hypercubes and a proof of the Sensitivity Conjecture. I didn’t know about the problem, but the paper is very readable (as long as you have some notion of matrix eigenvalues, basically) and the proof is very pretty. I cannot say that I have a good understanding of it (at least not in my definition of understanding maths), but I do understand enough to see that it’s very elegant. So that definitely enters “cool stuff” (if only for the reason “hey I read a (short) paper and I still understood ‘enough’ of it for my own satisfaction” 😉 ).
Cities:Skyline – The Board Game – actually, everything’s in the link title. It’s planned for October (Essen release?), it’s a cooperative, and that’s already enough to get me interested/curious 🙂
SMBC about mind privacy – since my own brain is particularly vulnerable to that attack, this made me laugh a lot 😉
