How Big is Infinity?

Tony Crilly is a Reader in Mathematical Sciences at Middlesex University, having previously taught at the University of Michigan, the City University in Hong Kong and the Open University. His principal research interest is the history of mathematics, and he has written and edited many works on fractals, chaos and computing. He is the author of the acclaimed biography of the English mathematician Arthur Cayley and the hugely successful 50 Mathematical Ideas You Really Need to Know.

• Introduction. What is mathematics for? - An introduction to purposes and prospects. Where do numbers come from? - From notches on bones to hexadecimals. Why are primes the atoms of mathematics? - Building blocks and the fundamental theorem of arithmetic. Which are the strangest numbers? - Real, irrational and transcendental numbers. Are imaginary numbers truly imaginary? - From the imaginary 'I' to octonions. How big is infinity? - Set theory and the infinity revolution. Where do parallel lines meet? - The birth of new geometries. What is the mathematics of the universe? - The Calculus miracle. Are statistics lies? - Data, proof and 'damned lies'. Can mathematics guarantee riches? - Uncertainty, chance and probability theory. Is there a formula for everything? - Mathematical recipes and the search for knowledge. Why are three dimensions not enough? - Higher dimensions, monster curves and fractals. Can a butterfly's wings really cause a hurricane? - Chaos theory, weather equations and strange attractors. Can we create an unbreakable code? - Ciphers, the Enigma machine and quantum computers. Is mathematics beautiful? - Music, art, golden numbers and the Fibonacci sequence. Can mathematics predict the future? - Mathematical models, simulations and game theory. What shape is the universe? - Topology, manifolds and the Poincare conjecture. What is symmetry? - Patterns, dualities and the fundamental nature of reality. Is mathematics true? - From Plato's reality to Godel's incompleteness theorems.
