8:49 PM | August linkdump

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. I never new that Mark Alan Stamaty, one of my favorite cartoonists, did the cover of the first They Might Be Giants album. Hey I keep saying […]

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

Hi, folks! Before the upcoming series of thematic blog posts (they are on their way, eager readers), I found a very interesting paper to discuss. The paper is this http://arxiv.org/abs/1408.1820 and the pdf file can be found here http://arxiv.org/pdf/1408.1820v1.pdf . The author of the … Continue reading → Tags: AdS group, Bacry, BH, black holes, Born reciprocal relativity, Buchdahl's bound, C-space relativity, classical theories, cosmic repulsion,

1:02 PM | My courses this fall at Columbia

Stat 6103, Bayesian Data Analysis, TuTh 1-2:30: We’ll be going through the book, section by section. Follow the link to see slides and lecture notes from when I taught this course a couple years ago.

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

Some links I've posted over on Google+ over the last couple of weeks (and reposted here, among other reasons, because I don't trust G+ to give me a usable interface for finding all of my old posts there):

Since a number of people asked, here are the slides from my ICM talk yesterday. I have also posted them on my preprints page. I believe the talk was recorded and the video will presumably be available from the ICM … Continue reading →

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.

1:03 PM | “Psychohistory” and the hype paradox

Lee Wilkinson writes: I thought you might be interested in this post. I was asked about this by someone at Skytree and replied with this link to Tyler Vigen’s Spurious Correlations. What’s most interesting about Vigen’s site is not his video (he doesn’t go into the dangers of correlating time series, for example), but his […]

11:23 AM | I love math and I hate the Fields Medal

I’ve loved math since I can remember. When I was 5 I played with spirographs and learned about periodicity, which made me understand prime numbers as colorful patterns on a page. I always thought 5-fold symmetry was the most beautiful. In high school I was incredibly lucky to attend HCSSiM and learn about the […]

6:51 AM | Museum of Anthropology

My photos from the UBC Museum of Anthropology are online now. Here is a sampling of thumbnails:
The museum is mostly devoted to Pacific Northwest First Nations art, but as a living culture rather than as something that happened in the past, so it includes a mix of older cultural artifacts with more modern art. It also has a gallery of Pacific Rim cultures, and a couple of rotating exhibit spaces; for our visit, one of them was on "urban aboriginal youth" and the other was a show of

2:14 AM | STEM forums

When visiting the exhibition hall at JSM 2014, I spoke with people from STEM forums on the Springer booth. The concept of STEM (why STEM? Nothing to do with STAN! Nor directly with Biology. It stands as the accronym for Science, Technology, Engineering, and Mathematics.) is to create a sort of peer-reviewed Cross Validated where questions would be […]

4:59 PM | Maryam Mirzakhani and Riemann surfaces

http://t.co/ZAdRPeiy8b Maryam Mirzakhani wins #FieldsMedal with Riemann surfaces Maryam Mirzakhani has made several contributions to the theory of moduli spaces of Riemann surfaces. In her early work, Maryam Mirzakhani discovered a formula expressing the volume of a moduli space with a given genus as a polynomial in the number of boundary components. This led her to obtain a new proof for the conjecture of Edward Witten on the intersection numbers of tautology classes on moduli space as well

Conservative commentators on education are mad about the new AP US History standards. The group’s president, Peter Wood, called the framework politically biased. One of his many complaints is about immigration: “Where APUSH sees ‘new migrants’ supplying ‘the economy with an important labor force,’ others with equal justification see the rapid growth of a population […]

3:27 PM | ICM2014 — Avila laudatio

As I said in my previous post, I don’t think I’m going to try all that hard to explain the work of the prizewinners, since it has been very well explained in other places (except that much more attention has gone to the Fields medallists than to the Nevanlinna prize winner — maybe I’ll try […]

Just when you thought you’d seen enough mathematical theatre projects, here’s another one. We’re Stuck! is an Arts Council funded piece of interactive theatre aimed at children aged 7-12 and their families. The project will explore the idea that getting stuck is part of doing maths, and not something to be feared. The aim is to promote... Read more »

I’m on a lot of dissertation committees. While most of the committees are for students in my department, many are not in my area of operations research. I’m surprised at how hard it can be to follow along to the bigger picture and/or to the technical details. Even when I completely understand the technical details, I […]

1:05 PM | Luck vs. skill in poker

The thread of our recent discussion of quantifying luck vs. skill in sports turned to poker, motivating the present post. 1. Can good poker players really “read” my cards and figure out what’s in my hand? For a couple years in grad school a group of us had a regular Thursday-night poker game, nickel-dime-quarter with […]

I have never eaten Vegemite---should I try it? I currently have no children---should I apply to adopt a child? In each case, one might imagine, whichever choice I make, I can make it rationally by appealing to the principles of decision theory. Not according to L. A. Paul. In her rich and fascinating new book, Transformative Experience, Paul issues two challenges to orthodox decision theory---they are based upon examples such as these.(In this post and the next, I'd like

Everyone I know who codes uses stackoverflow.com for absolutely everything. Just yesterday I met a cool coding chick who was learning python and pandas (of course!) with the assistance of stackoverflow. It is exactly what you need to get stuff working, and it’s better than having a friend to ask, even a highly knowledgable friend, because […]

10:44 AM | Worlds Without Domain

An article "Worlds Without Domain" arguing against the idea that possible worlds have domains. The abstract is: "A modal analogue to the "hole argument" in the foundations of spacetime is given against the conception of possible worlds having their own special domains".
