    We often see mathematical material in an abstract manner, but behind formal theorems and rigorous proofs, we can find significant applications to the real world. One example which has become crucial to our daily lives is cryptography. When we access a bank account online or purchase an item electronically, we rely on some method of cryptography to...

    There is a joke that when one counts something in linear algebra, the only possible results are 0, 1, and infinity.  What about in number theory?  Well, if we count the primes, we get infinity.  To get a finite number, we could try to count primes less than some fixed N.  It was proven in 1955 that something interesting happens...

    It is May 25, 1961, President Kennedy announced that the United States would land a person on the moon. But, in 1961 nobody actually knew how to get to the moon! It wasn't until 1963 that a viable flight path to the moon was found to exist. We will discuss the mathematics that made this path possible and some of the long...

    Abstract: Charles Darwin, in his On the Origin of Species, laid the foundation for all of modern biology. But he had doubts of his own theory: "I...confine myself to one special difficulty...actually fatal to my whole theory. I allude to the neuters or sterile females in insect communities...they cannot propagate their kind." Put another...

    Abstract: The first personal computing revolution took place not in Silicon Valley in the 1980s but in Pisa in the 13th Century. The medieval counterpart to Steve Jobs was a young Italian called Leonardo, better known today by the nickname Fibonacci. Thanks to a recently discovered manuscript in a library in Florence, the story of how this little...

    Abstract: Can we make objects invisible? This has been a subject of human fascination for millennia in Greek mythology, movies, science fiction, etc. including the legend of Perseus versus Medusa and the more recent Star Trek and Harry Potter. In the last decade or so there have been several scientific proposals to achieve invisibility. We will...
