By Leslie Larson PUBLISHED: 19:04 EST, 21 March 2013 | UPDATED: 11:52 EST, 22 March 2013 Let the insanity begin! March Madness kicked off with a bang on Thursday with millions of Americans glued to the games to see how their brackets would fare in the early stages. As the NCAA tournament brings out the bracketologist in all of us, one mathematician is encouraging people to keep expectations low because the odds are not in your favor. After running the numbers, DePaul University Math Professor Jeff Bergen estimates there is only a one in 9 quintillion (that's a 9 followed by 18 zeros) of filling out a perfect bracket. Serenity now.
