3:28 PM | Some quick disorganzed tips on classroom teaching
Below are a bunch of little things I typically mention at some point when I’m teaching my class on how to teach. But my new approach is to minimize lecturing, and certainly not to waste students’ time by standing in front of a group of them, telling them things they could’ve read at their own […] The post Some quick disorganzed tips on classroom teaching appeared first on Statistical Modeling, Causal Inference, and Social Science.

2:28 PM | ICM2014 — Hairer laudatio
I haven’t kept up anything like the frequency of posts at this ICM that I managed at the last one. There are at least three reasons for this. One is that I was in the middle of writing up a result, so I devoted some of my rare free moments to that. Another is that […]

1:45 PM | Boyhood: one more note
I thought of one more small thing, concerning the last scene. People made fun of that last scene where they take shrooms and go hiking in Big Bend.  But I liked this last scene.  It captures that feeling that, on the one hand, the past is past, but on the other hand, the past is always […]

As we transition from summer back into the academic year, there are a lot of things to work on this fall, but four big ideas in particular are going to be a focus for my work this semester.

11:10 AM | What can be achieved by Data Science?
This is a guest post by Sophie Chou, who recently graduated from Columbia in Computer Science and is on her way to the MIT Media Lab. Crossposted on Sophie’s blog. “Data Science” is one of my least favorite tech buzzwords, second to probably “Big Data”, which in my opinion should be always printed followed by a […]

This book has been in the works for some years now, and I’m thrilled to finally have a demo copy to show you. The book will be published by the American Mathematical Society. The demo copy has been produced (impressively … Continue reading →

6:30 PM | Time exchange rate
At some point in the past, computer time was more valuable than human time. The balance changed long ago. While everyone agrees that human time is more costly than computer time, it’s hard to appreciate just how much more costly. You can rent time on a virtual machine for around $0.05 per CPU-hour. You could […]

5:06 PM | Bohemian gravity
Tim Blais, a McGill University physics student made this really great a capella version of "Bohemian Rhapsody", called "Bohemian Gravity", with physics lyrics explaining superstring theory, like "Manifolds must be Kahler!" (lyrics here).Another article on this.

4:47 PM | Breuillard’s ICM talk: uniform expansion, Lehmer’s conjecture, tauhat
Emmanuel Breuillard is in Korea talking at the ICM; here’s his paper, a very beautiful survey of uniformity results for growth in groups, by himself and others, and of the many open questions that remain. He starts with the following lovely observation, which was apparently in a 2007 paper of his but which I was unaware […]

3:29 PM | The time the cops pulled their guns on me
This post is not about science.I'm writing this because the horrific news out of Ferguson, Missouri—the killing of an unarmed man and the subsequent assault on the populace and media—has been bringing back memories an experience I had with the police ten years ago in Chicago.I should be clear about why I'm choosing to share this. It's not because I think my own problems are particularly deserving of attention in comparison to the violence done to Michael Brown, Eric Garner, and […]

1:45 PM | Notes on Boyhood
Richard Linklater’s Boyhood is certainly the best movie I’ve seen this year, likely the best movie I’ll see this year.  But I don’t see a lot of movies.  After the spoiler bar, some notes on this one.  I meant to write this right after I saw it, but got busy, so no doubt I’ve forgotten some […]

10:14 PM | Munbai map [recycled art]
While my transfer from Terminal 1 to Terminal 2 was a bit hectic, with a security luggage scan before boarding a shuttle that would drive us to outside the terminal [next to slums that seemed to have direct access to the runways of the airport!), the brand new Terminal 2 was impressive as well as […]

The company that makes OldReader, the RSS reader I fled to after the sad demise of Google Reader, is from Madison!  OK, Middleton.  Still part of Silicon Isthmus.

3:36 PM | Mathematics is a unique aspect of human thought
http://t.co/h9CCSAaER0 #IsaacAsimov about #mathematics Mathematics is a unique aspect of human thought, and its history differs in essence from all other histories.As time goes on, nearly every field of human endeavor is marked by changes which can be considered as correction and/or extension. Thus, the changes in the evolving history of political and military events are always chaotic; there is no way to predict the rise of a Genghis Khan, for example, or the consequences of the short-lived […]

10:32 AM | Reinstatement
M-Phi readers may or may not have paid attention to the bizarre events during the last twelve months, over which I was initially dismissed by the University of Oxford, and smeared with lies in the national press. I described some of this in a statement Prof. Leiter put up on 26 March 2014:From late 2013, Oxford proceeded with a prosecution, involving failures of due process and proportionality, despite the support I received from my College and several members of the Faculty. The prosecution […]

3:16 PM | ICM2014 — Bhargava laudatio
I ended up writing more than I expected to about Avila. I’ll try not to fall into the same trap with Bhargava, not because there isn’t lots to write about him, but simply because if I keep writing at this length then by the time I get on to some of the talks I’ve been […]

2:39 PM | Plagiarism, patchwriting, Perlstein
Some people are complaining about Rick Perlstein’s new book, claiming that some passages are plagiarized.  Most of my friends think this is nonsense. Here’s a passage from Craig Shirley’s Reagan’s Revolution: Even its ‘red light’ district was festooned with red, white, and blue bunting, as dancing elephants were placed in the windows of several smut peddlers.
