@thesasho Sorry to nitpick but, as written, this isn’t true without bounding d in terms of the exponential growth rate of the size of the subset.

[Henry Pfister @HenryDPfister]

@CihanPostsThms In what axiomatic system? Since CH is independent of ZFC, this would seem to imply that (1) cannot be proven in ZFC. Does the result generalize to systems (e.g., ZFC + other axioms) where the CH is either true or false?

[Henry Pfister @HenryDPfister]

@ProfKinyon What axioms are you using for set theory? ZFC also says "nah" (https://t.co/dHudV9Bjbk) but Frege's set theory says yup but is inconsistent

[Henry Pfister @HenryDPfister]

@MountainOfMoon Indeed, this is a very cool result. I would also add that their theorem lower bounds the "sharpness" by an increasing function of the minimum distance. So, one might say that every sequence of codes whose minimum distance grows without bound has a sharp threshold.

@elonmouosk @Andrea__M Says the faker bot pretending to be Musk 😂

So glad I won't need to find a new place for my research science updates 😀 (twitter: you can turn down the revenue rate now... it seems like my feed has been crammed with ads lately)

It's great to see Rudiger receive this well-deserved honor!

[Andrea Montanari @Andrea__M]

The Shannon award to Rudiger Urbanke is both terrific news and a long overdue recognition to one of the most influential information and coding theorists of the last quarter century. 1/n

@ccanonne_ Going from Bernoulli (or Binomial) to Gaussian is also a standard trick for Efron-Stein -> Poincare and Hypercontractivity: https://t.co/GpoU2NABhV
For anti-concentration, see Theorem 6 in https://t.co/ESwmW2ITs2

[Henry Pfister @HenryDPfister]

@ccanonne_ You might get from Poisson to Gaussian by noting that a centered normalized Poisson converges in distribution to a standard Gaussian: https://t.co/f1phGNBWul

[Henry Pfister @HenryDPfister]

@lpachter This sounds like a suggestion to teach continuous-time discrete-valued jump Markov processes before teaching basic calculus. For some simple models, this is possible but the intuition behind many important concepts (e.g., generating functions) really requires calculus.

@QuantumMemeing PSA: Never try to explain Schrödinger’s cat experiment to a cat lover on a date

[Henry Pfister @HenryDPfister]

@ProbFact I think this needs to be stated more precisely. For an n-vector of std Gaussians with large n, the squared Euclidean dist to the mean concentrates around n+o(n). Defining the std deviation as the sqrt of this, the Euclidean dist is less than 2 sqrt(n) with prob 1 as n increases

[Henry Pfister @HenryDPfister]

@MitchellCoding @NSF Congratulations!!! That’s great news 👏

@lupusorina @gautamcgoel Have you ever gone out to eat in Zurich? Not that like McDonald's but a Zurich big mac is $14 while an USA big mac is $6
