To exist is to do mathematics — Erdős | Tangente
Pál Erdős (1913-1996) is renowned for his eccentric behavior, but above all for the brilliance of his ideas. His ingenious methods, off the beaten track, his countless publications, and his constant wandering built the image of a legendary scholar.

Computer-assisted proofs | Tangente
Can a machine prove a theorem? Probably not without a human to guide it, but computers are becoming increasingly useful assistants—for example, by turning a human proof into a formal one. Spectacular developments and applications are currently under way.

The relationship between language and reality lies at the heart of Wittgenstein's thought. The issue takes on its full significance when it comes to mathematical entities. What if philosophers speculating about the rigorous logical foundations of these abstractions were on the wrong track?

Fermat's false theorem
Fermat formulated many theorems, but one of them proved false: he conjectured that all "Fermat numbers" were prime, an error exposed by Euler. This notably illustrates how induction can lead us astray.
