Skeptics and philosophers throughout history have never been afraid to ask the big questions. But what about the biggest questions of all - about infinity, higher dimensions and logic itself? These are questions mathematicians have been working on - but not without venturing into philosophy and even skepticism. In this talk, Katie will discuss some icons of mathematics who are also (or should be) icons of skepticism and the history of philosophy.

Katie Steckles is a mathematician who works in public engagement, giving talks about maths and performing at science festivals. She's also well totally an atheist and that.
