1:06 PM | Notices of the AMS is killing it
I am somewhat surprised to hear myself say this, but this month’s Notices of the AMS is killing it. Generally speaking I think of it as rather narrowly focused but things seem to be expanding and picking up. Scanning the list of editors, they do seem to have quite a few people that want to […]

4:58 AM | The “bounded gaps between primes” Polymath project – a retrospective
The (presumably) final article arising from the Polymath8 project has now been uploaded to the arXiv as “The “bounded gaps between primes” Polymath project – a retrospective“.  This article, submitted to the Newsletter of the European Mathematical Society, consists of personal contributions from ten different participants (at varying levels of stage of career, and intensity […]

12:27 AM | How weird is it that three pairs of same-market teams made the playoffs this year?
The Major League Baseball postseason is starting just as I write this. From the National League, we have Washington, St. Louis, Pittsburgh, Los Angeles, and San Francisco. From the American League, we have Baltimore, Kansas City, Detroit, Los Angeles (Anaheim), and Oakland. These match up pretty well geographically, and this hasn’t gone unnoticed: see for […]

12:00 AM | Limits of prediction: stochasticity, chaos, and computation
Some of my favorite conversations are about prediction and its limits. For some, this is purely a practical topic, but for me it is a deeply philosophical discussion. Understanding the limits of prediction can inform philosophy of science, mind, and even questions of free-will. As such, I wanted to share with you a World Science […]

10:14 PM | ABC model choice via random forests [expanded]
Today, we arXived a second version of our paper on ABC model choice with random forests. Or maybe [A]BC model choice with random forests. Since the random forest is built on a simulation from the prior predictive and no further approximation is used in the process. Except for the computation of the posterior [predictive] error […]

8:47 PM | Ritratti: Winifred Edgerton Merrill
Winifred Edgerton Merrill fu la prima americana ad ottenere un dottorato in matematica presso la Columbia University nel 1886. Nella sua tesi sviluppò una rappresentazione geometrica degli infinitesimi in diversi sistemi di coordinate, utilizzando lo jacobiano per per derivare le trasformazioni tra gli integrali nei diversi sistemi.Tra matematica e astronomiaNata a Ripon, nel Wisconsin, il 24 settembre del 1862 da Emmet e Clara Edgerton, si trasferisce con la famiglia a New York intorno […]

3:55 PM | Are Ivy League schools overrated?
I won’t actually answer the above question, as I am offering neither a rating of these schools nor a measure of how others rate them (which would be necessary to calibrate the “overrated” claim). What I am doing is responding to an email from Mark Palko, who wrote: I [Palko] am in broad agreement with […] The post Are Ivy League schools overrated? appeared first on Statistical Modeling, Causal Inference, and Social Science.

2:52 PM | The chocolate factory gone up in smoke
There was a major fire near my house yesterday with many fire-engines rushing by and a wet smoke smell lingering by the whole night. As I found out during my early morning run, the nearby chocolate factory had completely burned. Actually, sixteen  hours after the beginning of the fire, the building was still smouldering, with […]
