In 1901, british mathematician Bertrand Russell wrote that "mathematics may be defined as the subject in which we never know what we are talking about". This sentence may seem really odd as mathematics are often considered the discipline of rigor and precision. This talk aims to show that not only mathematics can be imprecise, but that it's the very principle of this discipline to be imprecise. And some of the greatest problems in the history of mathematics can only be solved if we don't know what we are talking about.


Mickaël Launay graduated from the Ecole Normale Supérieure Ulm in 2009 with a degree in maths. He holds a PhD in probability. For over fifteen years, he has been involved in popularization of mathematics in France and curates the Micmaths Youtube channel, which has garnered 22 million views and on which he has over 300,000 subscribers. He is also the author of the best seller "It All Adds Up" (La gran novela de las matematicas).
