Wrestling with Primes
This video resource from Teachers TV features presenter Matthew Tosh who looks at the complex subject of prime numbers, from the theories relating to them to some of their uses, in an information-packed video for teachers of mathematics.
For centuries, mathematicians have been searching for both larger primes and ways of breaking numbers down into their prime factors. Here we see how prime numbers are used in cryptography algorithms to help keep our money safe. Starting with Euclid's fundamental theorem of arithmetic, this video explains the role prime numbers play in internet security.
