1:11 PM | Parsons #5: Gödel on analyticity
The delay in getting round to talking about the next couple of papers in Charles Parsons’s Philosophy of Mathematics in the Twentieth Century signals, I’m afraid, a certain waning enthusiasm. I’m still hopeful that the essays in Part II of … Continue reading →

 A smallish bowl of math ghoulash from this week: 1)  Ed Frenkel's recent public talk at Oxford (GOOD stuff): http://podcasts.ox.ac.uk/love-and-math 2)  The Fourier Transform (from The Guardian): http://www.theguardian.com/science/2014/jul/13/fourier-transform-maths-equations-history 3)  Another interesting (in a nerve-wracking way) puzzle from Presh Talwalkar (Zeckhauser’s Paradox):   http:/

9:48 PM | Abstract Structure
Draft of a paper, "Abstract Structure", cleverly called that because it aims to explicate the notion of "abstract structure", bringing together some things I mentioned a few times previously.

6:21 PM | The “P-values overstate the evidence against the null” fallacy
1. What you should ask… Discussions of P-values in the Higgs discovery invariably recapitulate many of the familiar criticisms of P-values (some “howlers”, some not). When you hear the familiar refrain, “We all know that P-values overstate the evidence against the null hypothesis”, denying the P-value aptly measures evidence, what you should ask is: “What do you mean […]

11:00 AM | Jordan Ellenberg... Getting It Right
 Math-Frolic Interview #25 "Mathematics as currently practiced is a delicate interplay between monastic contemplation and blowing stuff up with dynamite."                -- Jordan Ellenberg in "How Not To Be Wrong" "He’s really somewhere between a mathematician and a stand-up comedian, and to be honest I don’t know which one he’s better at, although he is a deeply talented mathematician."

11:54 AM | Interview at 3am magazine
Here is the shameless self-promotion moment of the day: the interview with me at 3am magazine is online. I mostly talk about the contents of my book Formal Languages in Logic, and so cover a number of topics that may be of interest to M-Phi readers: the history of mathematical and logical notation, 'math infatuation', history of logic in general, and some more. Comments are welcome!

3:40 AM | Higgs discovery two years on (2: Higgs analysis and statistical flukes)
I’m reblogging a few of the Higgs posts, with some updated remarks, on this two-year anniversary of the discovery. (The first was in my last post.) The following, was originally “Higgs Analysis and Statistical Flukes: part 2″ (from March, 2013).[1] Some people say to me: “This kind of reasoning is fine for a ‘sexy science’ like high energy physics (HEP). But I maintain […]

2:36 AM | Methodology in the Philosophy of Logic and Languages
This M-Phi post is an idea Catarina and I hatched, after a post Catarina did a couple of weeks back at NewAPPS, "Searle on formal methods in philosophy of language", commenting on a recent interview of John Searle, where Searle comments that"what has happened in the subject I started out with, the philosophy of language, is that, roughly speaking, formal modeling has replaced insight".I commented a bit underneath Catarina's post, as this is one thing that interests me. I'm writing a more […]

2:53 PM | Higgs Discovery 2 years on (1: “Is particle physics bad science?”)
July 4, 2014 was the two year anniversary of the Higgs boson discovery. As the world was celebrating the “5 sigma!” announcement, and we were reading about the statistical aspects of this major accomplishment, I was aghast to be emailed a letter, purportedly instigated by Bayesian Dennis Lindley, through Tony O’Hagan (to the ISBA). Lindley, according […]

11:15 AM | Infinity and Angst (David Foster Wallace)
I've moved this Sunday reflection, which grew longer-than-usual, to here from its customary spot at Math-Frolic:   "Here is a quotation from G.K. Chesterton: 'Poets do not go mad but chess players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not attacking logic: I only say that this danger does lie in logic, not in imagination.' Here also is a snippet

4:55 AM | Mathematics in the light of Maturana’s biology of cognition
As I have investigated all of the things in science and mathematics that get my attention, I have developed an impression of mathematics that, philosophically, seems most consistent with Humberto Maturana’s biology of language.  Maturana outlines his perspective in great detail in an essay by the same name that appeared in 1978 in the text [...]

3:35 AM | Some ironies in the ‘replication crisis’ in social psychology (1st installment)
There are some ironic twists in the way social psychology is dealing with its “replication crisis”, and they may well threaten even the most sincere efforts to put the field on firmer scientific footing–precisely in those areas that evoked the call for a “daisy chain” of replications. Two articles, one from the Guardian (June 14), and a second from […]

11:00 AM | Apologies to John Steinbeck...
A blurb today on yet another fine new book for the math novice or enthusiast: "The Grapes of Math" by Alex Bellos (oddly, the title is the same as an earlier math book for youngsters by Greg Tang). I very much enjoyed Bellos' prior work, "Here's Looking At Euclid," (American title). Publicity for Bellos' latest offering, however, seemed to focus on what seemed some trivial/light matters, and

9:26 PM | Sean Carroll: "Physicists should stop saying silly things about philosophy"
Readers probably saw this already, but I mention it anyhow. Physicist Sean Carroll has a 23 June 2014 post, "Physicists should stop saying silly things about philosophy", on his blog gently criticizing some recent anti-philosophy remarks by some well-known physicists, and trying to emphasize some of the ways physicists and philosophers of physics might interact constructively on foundational/conceptual issues. Interesting comments underneath too.
