Jay “should replace the Brooks brothers on the NYT op-ed page” Livingston writes: There it was again, the panic about the narcissism of millennialas as evidenced by selfies. This time it was NPR’s podcast Hidden Brain. The show’s host...Show More Summary

Finite time blowup for a supercritical defocusing nonlinear Schrodinger system

I’ve just uploaded to the arXiv my paper Finite time blowup for a supercritical defocusing nonlinear Schrödinger system, submitted to Analysis and PDE. This paper is an analogue of a recent paper of mine in which I constructed a supercritical defocusing nonlinear wave (NLW) system which exhibited smooth solutions that developed singularities in finite time.

Guppies: Study sorts the maths whizzes from the dunces

(Springer) Some guppies have a better sense of maths than others. It allows some to find the biggest shoal possible in which to be protected against predators, while others are better at choosing fruitful foraging ground. This is according...Show More Summary

Using Stan in an agent-based model: Simulation suggests that a market could be useful for building public consensus on climate change

Jonathan Gilligan writes: I’m writing to let you know about a preprint that uses Stan in what I think is a novel manner: Two graduate students and I developed an agent-based simulation of a prediction market for climate, in which traders...Show More Summary

Mighty oaks from little acorns grow

Eric Loken writes: Do by any chance remember the bogus survey that Augusta National carried out in 2002 to deflect criticism about not having any female members? I even remember this survey being ridiculed by ESPN who said their polls showed much more support for a boycott and sympathy with Martha Burke. Show More Summary

Frustration with published results that can’t be reproduced, and journals that don’t seem to care

Thomas Heister writes: Your recent post about Per Pettersson-Lidbom frustrations in reproducing study results reminded me of our own recent experience that we had in replicating a paper in PLOSone. We found numerous substantial errors...Show More Summary

So little information to evaluate effects of dietary choices

Paul Alper points to this excellent news article by Aaron Carroll, who tells us how little information is available in studies of diet and public health. Here’s Carroll: Just a few weeks ago, a study was published in the Journal of Nutrition...Show More Summary

Some U.S. demographic data at zipcode level conveniently in R

Ari Lamstein writes: I chuckled when I read your recent “R Sucks” post. Some of the comments were a bit … heated … so I thought to send you an email instead. I agree with your point that some of the datasets in R are not particularly relevant. Show More Summary

Survey weighting and that 2% swing

Nate Silver agrees with me that much of that shocking 2% swing can be explained by systematic differences between sample and population: survey respondents included too many Clinton supporters, even after corrections from existing survey adjustments. Show More Summary

A friend of a friend is ... a dense network

human-, computer- and fairy-chess

There was this hilarious message around move 60: “The computer has just announced that white mates in 31 moves. Of course, the only two people in the building who don’t benefit from that knowledge are behind the pieces.” The position below comes from the preface of Lewis Carroll’s Through the Looking-Glass The old notation for...

How can you evaluate a research paper?

Shea Levy writes: You ended a post from last month [i.e., Feb.] with the injunction to not take the fact of a paper’s publication or citation status as meaning anything, and instead that we should “read each paper on its own.” Unfortunately, while I can usually follow e.g. Show More Summary
