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 →

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.

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

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,

Stupiti che 1 non sia primo? Scopriamo insieme perché è "solo" l'unità!Abbiamo già visto come, partendo dai numeri primi, si possa sviluppare un discorso più o meno approfondito sulle fondamenta matematiche. Altrettanto fondamentale, però, si rivela provare a rispondere alla domanda su quale sia il numero primo più piccolo. E', infatti, abbastanza noto come il numero 1 sia stato ora inserito ora escluso dalla lista dei numeri primi, ottenendo in alcuni casi lo status di più piccolo tra […]
