Mathematics

So much of our lives are lived online these days. Whether it’s paying bills or socializing the concern about keeping our personal information is ever-present. However, a team of mathematicians from around the world have been working on a database that will make our internet, credit and debit transactions even more secure. Our guest, Anna Haensch, assistant professor of mathematics at Duquesne University has been part of this effort and joins us to explain how it will impact our lives.

In school we were all taught about the number represented by the symbol π. Our understanding of the number might be a bit foggy, but most of us remember it has something to do with a circle and that it is 3.14.  In reality, the irrational number (by definition) goes on forever, but it starts with 3.141592653. 

For the last several years, the popularity of so-called “Pi Day,” or March 14 (3/14), has been growing in the U.S., and Saturday will mark what many are calling “Super Pi Day,” where we can add the next two digits of the mathematical super number (3/14/15). And if you really want to geek out you can make sure you are near a clock at 9:26:53 a.m. (3/14/15 9:26:53).
