SUMMARY:Oh That's How Google Works!
DESCRIPTION:"Imagine a library containing 25 billion documents, but with n
o centralized organization and no librarians. In addition, anyone may add
a document at any time without telling anyone." This is the vision for w
hich Larry Page and Sergey Brin, the founders of Google, designed their G
oogle Search Engine. Faced with many challenges for building the site, ce
rtainly the fundamental question is how to effectively probe billions of
documents and identify those that are most related to what you are seekin
g. All students are familiar with Google, but few would ever suspect that
two undergraduate level math courses are at the basis of the Google algo
rithm. In Calculus II we learn the concept of convergence and how to appl
y it in practice. Similarly, in Linear Algebra we discover the practical
utility of problems that can be formulated in terms of an eigenvalue prob
lem. Both concepts are very important in their own right, however Page an
d Brin showed that it was possible to bring the power of both concepts to
bear on their problem. When you enter a subject in Google's search bar t
here is an algorithm that searches their database for the most relevant m
atches to what you have entered. Intrinsic to this algorithm is an eigenv
alue problem that is set up and inside of this problem is an iteration or
sequence that must converge in order for the algorithm to yield useful o
utput. This talk will not only reveal Google's surreptitious mathematical
tools for finding the topics you desire when searching the web, but give
insight into the life of a math graduate student and the employment oppo
rtunities for those interested in similar fields.
