Title: Mathematics Makes Communication Possible

How do we ensure security in internet communications, for example, when using a credit card to make an online purchase? How do we efficiently transmit or store data, such as satellite pictures from outer space or music on a CD or an iPhone, in such a way that we can reliably read that data even in the presence of noise, such as electronic interference or a scratch or dust? In this talk, we will see that the answers to both of these questions hinge on beautiful mathematics that was once thought to be too abstract to be of any practical use.
