Tomorrow, I'm off to Cracow, to give two 90 minutes long workshops on adaptive logics. I think I'll talk about various ways paraconsistent logics can be obtained, the way they generate inconsistency-adaptive logics, the standard format of adaptive logics and some other examples of adaptive logics, not related to paraconsistency. Anyway, if you're in Cracow and speak Polish, feel free to pop in (more details here ). Please do remember what happens to those who ask tricky questions , though. ;)

There's a postdoc position in Amsterdam, related to history of logic, Bolzano, Tarski, Lesniewski etc. More details here .

I've just noticed that a very nice book about number theory by Melvin Fitting and Greer Fitting is freely available online here . Here's a bit from the introduction. A preface is supposed to explain why you should read the book. Like most prefaces, this one will make more sense after the fact. Nevertheless, here goes. Most mathematicians believe (rather strongly) that numbers behave in certain well-defined ways. This belief can not be justified by personal experience. No mathematician has `seen' more than a finite, probably small, collection of numbers. Instead mathematicians justify their beliefs by giving proofs. In practice, this means that certain facts about numbers are accepted as `obvious', and used in carefully reasoned arguments for the correctness of other facts that are less obvious, or possibly not obvious at all. Since mathematicians generally are concerned to establish the nonobvious, little thought is customarily given as to why the `obvious' facts ar...

Philosophy Talk is a radio show, their past programs are available online - well, you can listen online without paying, at least to those that I've tried, but it seems you have to pay to download. ;) Their list of topics sounds pretty cool. It includes: Beliefs gone wild Capital punishment The Copyright wars Different cultures, different selves Animal minds Bodies for sale Digital selves Morality of food We've been framed: how language shapes politics Varietes of love Athletic beauty Philosophy of wine Immigration Marriage and monogamy If truth is so valuable, why is there so much BS? The erotic vs. the pornographic and many others.

Here you can find an interesting poem by Geoffrey K. Pullum, Scooping the Loop Snooper, treating about the halting problem and its undecidability.
