11:00 PM | Poundstone on People and Predictions
"Rock Breaks Scissors"  by William Poundstone I keep seeing William Poundstone's latest book, "Rock Breaks Scissors" in the 'business' sections of bookstores… which I think is ashamed, because a lot of readers who would enjoy it may miss it there. More appropriately, and like most Poundstone books, it should be in a science/math area, or perhaps under psychology. Poundstone is one of my

7:21 AM | What makes a mathematical proof beautiful?
(Cross-posted at NewAPPS)In December, I will be presenting at the Aesthetics in Mathematics conference in Norwich. The title of my talk is Beauty, explanation, and persuasion in mathematical proofs, and to be honest at this point there is not much more to it than the title… However, the idea I will try to develop is that many, perhaps even most, of the features we associate with beauty in mathematical proofs can be subsumed to the ideal of explanatory persuasion, which I take to be the […]

1:34 AM | A crucial missing piece in the Pistorius trial? (i)
Time for a break with a “Rejected Post”[i] There’s one crucial point that Prosecutor Nell overlooked and failed to employ in the Oscar Pistorius trial–or so it appears. In fact I haven’t heard anyone mention it—so maybe it’s not as critical as I think it is. Before revealing (what I regard as the crucial missing […]

4:00 AM | Consequences of Triadic Relation Irreducibility : 2
From time to time I come to the realization that there are ways of reading Peirce that make no sense to me.  When I stop to think about the potential sources of that evident divergence from common sense, the first … Continue reading →

4:15 PM | The Very Short Teach Yourself Logic Guide

12:00 AM | So You Want Some Math History...
Recently finished a quickread of history professor Amir Alexander's "Infinitesimal," which has received plenty of rave reviews, a few of which I'll reference below, (as I won't fully review it myself): http://tinyurl.com/pe2dd7w http://tinyurl.com/nopb85a http://tinyurl.com/mxchx6h For whatever reason, I've never been much fascinated with math history (at least not pre-19th century history)

4:17 PM | Apologies
On behalf of the M-Phi contributors, I want to sincerely apologize to our readers for the misguided and inappropriate post that was online at M-Phi for four days (now taken down, as well as all other posts referencing the Oxford events). The moderation structure of the blog was such that none of us could do anything to take it down, except for pleading with the author to do so.The structure and moderation of the blog will change completely now; Jeffrey Ketland will no longer be a contributor […]

2:56 PM | The Oxford Lynch Mob
It is a rare experience for victims of long-term stalking, violent assault and harassment to be harassed by a gang of aggressive Oxbridge thugs. As I put it in March 2014 on Prof. Leiter's blog:[....] behind the scenes a group of graduate students, including some of the signatories of the Open Letter of 5 March 2014, had been campaigning the University to have my contact with students suspended and me fired. My supervisions were reassigned, my seminars were postponed and then reassigned to my […]

4:04 AM | Teach Yourself Logic
Peter Smith, long ago a Cambridge colleague of mine, whose blog is Logic Matters, regularly updates his Teach Yourself Logic Study Guide, an annotated reading list for mathematical logic. It's useful for students, or anyone really, who want to do some self-study. Version 12.0 of the guide can be downloaded here.

11:00 AM | Robin Williams Redux...
Now for something completely different (for MathTango)… I've written before how much I admire Cathy O'Neil's keen ability to touch on varying topics over at her blog. Despite coming from a mathematics academic background and titling her blog "Mathbabe," Cathy writes on a wide range of topics that rattle around in her head. So I'll sorta take that cue today to veer off and relate an odd,

5:34 PM | What we see when….
I recently listened to Krys Boyd’s interview with Peter Mendelsund, author of the new book What We See When We Read,  on North Texas’ public radio. Mendelsund is an award-winning book jacket designer. The interview had the effect of connecting his thoughts about reading to thoughts that I have had about mathematics. It wasn’t immediately [...]

3:04 PM | Breaking the Law (of likelihood): only way to keep their fit measures in line (A)
An Assumed Law of Statistical Evidence (law of likelihood) Nearly all critical discussions of frequentist error statistical inference (significance tests, confidence intervals, p- values, power, etc.) start with the following general assumption about the nature of inductive evidence or support: Data x is better evidence for hypothesis H1 than for H0 if x are more probable under H1 than […]
