| | | | | Gödel's incompleteness theorems have been hailed as "the greatest mathematical discoveries of the 20th century" - indeed, the theorems apply not only to mathematics, but all formal systems and have deep implications for science, logic, computer science, philosophy, and so on. In this post, I'll give a simple but rigorous sketch of Gödel's First Incompleteness ... | |

| | | | | A standard menu for a first mathematical logic course might be something like this: (1) A treatment of the syntax and semantics of FOL, presenting a proof system or two, leading up to a proof of a Gödel's completeness theorem (and then a glance at e.g. the compactness theorem and some initial implications). (2) An [...] | |

| | | | | After writing about some well known people with degrees in mathematics, I was moved to re-listen to some old Tom Lehrer songs on YouTube. I decided I'd post some links to his more mathematical songs here. Enjoy. First, "Lobachevsky," a song about the Russian mathematician Nikolai Lobachevsky and his discovery of non-Euclidean geometry, which some... | |
