On the morning of September 11, 2001, millions of Americans, and many more around the world, woke up to heart-wrenching news of a horrific magnitude. Two planes had collided into the twin towers of the World Trade Center in New York, a third rammed into the Pentagon in Washington, D.C., and yet a fourth crash-landed in Philadelphia.

More specifically, the technology might be smart enough to associate that John Doe from Ireland had a 3.32 GPA in his engineering classes, even though he did not buy any engineering books from the bookstore. This type of technology is very powerful source of
