BBC FOUR celebrated mathematics and the beauty of numbers with a series of programmes about this most precise and exacting of all intellectual disciplines. Throughout the night, the channel showed films offering insights into the minds of great mathematicians, revealing the stories behind some of the great mathematical breakthroughs. The BBC's celebration of mathematics has a strong Oxford flavour: Marcus du Sautoy presents `Music of the Primes'; `Breaking the Code' draws on Andrew Hodges' biography of Alan Turing; many of the mathematical ideas in Escher's work were suggested by Roger Penrose; and of course Andrew Wiles was an Oxford undergraduate. Some of the programmes are available as documentaries in CosmoLearning,  underlined and hyperlinked, such as:
The Music of the Primes
Breaking The Code
Fermat's Last Theorem
