In 1931, the Austrian logician Kurt Gödel pulled off arguably one of the most stunning intellectual achievements in history. Mathematicians of the era sought a solid foundation for mathematics: a set ...

GENEVA, SWITZERLAND - APRIL 19: A detailed view of the blackboard with theoretical physics equations in chalk by Alberto Ramos, Theoretical Physics Fellow and visitor, Antonio Gonzalez-Arroyo from the ...

Last week I explained how a then 25-year-old logician, Kurt Gödel, overturned a basic assumption of many mathematicians in the early 20th century. Even as experts were building a seemingly firm ...

"All Cretans are liars", said Epimenides, a Cretan. But this means that his statement must be a lie too. But then it is false that Cretans are liars and the statement must be true. So what now?

The surprise of Kurt Gödel's incompleteness theorem of 1931 lay not so much in the incompleteness itself, but that it was found in so simple a mathematical theory as first-order arithmetic. It follows ...

Robyn Williams: And so to the greatest discovery in science. Here Pauline Newman celebrates the centenary of Kurt Gödel, Flacco's inspiration from Vienna. Paul Davies: I'm sometimes asked, 'What was ...

Earlier today I set you the puzzle below, which is based on Gödel’s incompleteness theorem. As I discussed in the original post, this theorem is one of the most famous in maths and states that in any ...
