10:30 PM | Suggested readings for PhD students?
Earlier this month, at the usually highly admirable The Philosopher’s Stone, Robert Paul Wolff posted a list of “twenty-five books by great philosophers that every grad student should read by the time he or she gets the PhD”. The list was … Continue reading →

4:36 AM | Poe’s cosmology
A post from John Horgan with the title Did Edgar Allan Poe Foresee Modern Physics and Cosmology? quickly got my attention. Horgan writes in response to an essay by Marilynne Robinson in the February 5 New York Review of Books where Poe’s book-length prose poem Eureka was brought to his attention. Eureka was written by [...]

7:49 PM | Being smart, being judged smart

Here’s the follow-up to my last (reblogged) post. initially here. My take hasn’t changed much from 2013. Should we be labeling some pursuits “for entertainment only”? Why not? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I had said I would label as pseudoscience or questionable science any enterprise that regularly permits the kind of ‘verification biases’ in the statistical dirty laundry list.  How regularly? (I’ve been asked) […]

10:24 AM | Review of Williamson's Tetralogue
By Catarina Dutilh Novaes(Cross-posted at NewAPPS)I've been asked to write a review of Williamson's brand new book Tetralogue for the Times Higher Education. Here is what I've come up with so far. Comments are very welcome, as I still have some time before submitting the final version.

4:56 AM | Power Analysis and Non-Replicability: If bad statistics is prevalent in your field, does it follow you can’t be guilty of scientific fraud?
If questionable research practices (QRPs) are prevalent in your field, then apparently you can’t be guilty of scientific misconduct or fraud (by mere QRP finagling), or so some suggest. Isn’t that an incentive for making QRPs the norm?  The following is a recent blog discussion (by  Ulrich Schimmack) on the Jens Förster scandal: I thank Richard Gill for […]

5:36 PM | John Shepherdson, 1926-2015
Sad news from Philip Welch at Bristol:  John Shepherdson has died. I deeply regret having to impart the very sad news that John Shepherdson died in Bristol on Thursday of an inoperable sarcoma. John was a founder of the BLC (together with Robin Gandy if I remember rightly). His own work was in many areas, starting with set theory, then recursion theory (inventing the register machine in a paper with Sturgis), models of arithmetic, incompleteness phenomena, and towards the end of his career […]

Every mathematician and philosopher should watch this video by Sarah-Jane Leslie (Philosophy, Princeton) on her study with Andrei Cimpian (Psych, Illinois). Takes just 11 minutes.

1:43 PM | What meaning can and cannot be: Lessons from real life, Part 2
The problem of fictional discourse -- do statements involving fictional objects have truth-values or are they truth-valueless; if the former, how are these truth values determined? -- is one that goes back at least to Frege (his views on the compositionality of language and what the referent of a sentence is entail that sentences which have non-referring parts have no truth-value) and for which no adequate solution has yet been found, given, e.g., the publication of books such as Time Crane's […]

7:40 PM | Letters From a Mathematician
Several years ago I skimmed through Ian Stewart's little book, "Letters To A Young Mathematician," and it didn't register much with me, not really being a fan of "Letters to..." sorts of books. But I just re-read it, with the benefit of a few more years immersion in mathematical debates, and especially Keith Devlin's notion of "mathematical thinking," and suddenly enjoyed it immensely! Indeed,

5:16 AM | “Only those samples which fit the model best in cross validation were included” (whistleblower) “I suspect that we likely disagree with what constitutes validation” (Potti and Nevins)
So it turns out there was an internal whistleblower in the Potti scandal at Duke after all (despite denials by the Duke researchers involved ). It was a medical student Brad Perez. It’s in the Jan. 9, 2015 Cancer Letter. Ever since my first post on Potti last May (part 1), I’ve received various e-mails and phone calls from people wishing to confide their inside […]
