LivMS Event: * *Date:* 30 Oct, 2013 * *Time:* 17:30 * *Presenter:* Ben Sparks * *Title:* Creation of Number * *Audience:* Year 10 up * *Venue:* University of Liverpool, Chadwick Large Lecture Theatre * *Contact:* Peter Giblin, pjgiblin@liv.ac.uk ---- Ben Sparks is a teacher, freelance mathematician, musician and speaker http://www.bensparks.co.uk/ Where do numbers come from? A whistle-stop tour of some of the exciting bits in the development of number, from integers, rationals, irrationals, all the way to complex numbers - with some proofs and fractals thrown in... Along the way: Who killed Hippasus and why? Just why is A4 paper 297mm long? How do you know when there are -1 sheep in a field? What is the square root of -1? Why does it matter? Is maths created by us, or are we discovering eternal truth?
