“Of all of equations on the list, Bayes’ Theorem may stand out on its own merits as being one of the most recognizable and it might even qualify as a poster child for the statistical revolution sweeping our industry. It rose from obscurity to being used for spam detection and with such applications as classifiers, Machine Learning, Data Mining and more. Mathematically it is part of a rift in statistics and probability and I confess I may not yet call myself “an initiate of the bayesian conspiracy” but it hard to deny its utility plus there seems to be a more axiomatic basis that relates to Boolean Logic Set Theory, which makes it all the more alluring.” - Geoff Moes

“… The students that are successful look at that challenge, wrestle with feelings of inadequacy and stupidity, and begin to take steps hiking that mountain, knowing that bruised pride is a small price to pay for getting to see the view from the top. They ask for help, they acknowledge their inadequacies. They don’t blame their lack of intelligence, they blame their lack of motivation … You’re so young, way too young to be worried about not being smart enough. Until you’re so old you start going senile, you have the opportunity to make yourself “smarter.” And I put that in quotes because “smart” is really just a way of saying “has invested so much time and sweat that you make it look effortless.” You feel like you are burnt out or that you are on the verge of burning out, but in reality you are on the verge of deciding whether or not you will burn out. It’s scary to acknowledge that it’s a decision because it puts the onus on you to to do something about it, but it’s empowering because it means there is something you can do about it. So do it.” -Inri137

“That’s the cool thing about it,” Engelhaupt said. “The book is kind of a living document.”

“Recently I set out to hold a Battleship programming tournament here among some of the undergraduates. Naturally, I myself wanted to win. So, I got to thinking about the game, and developed what I like to call “the linear theory of battleship”. A demonstration of the fruits of my efforts can be found here. Below, my aim is to guide you through how I developed this theory, as an exercise in using physics to solve an interesting unknown problem.”

spurpura: ” … The debate should be about the incentive systems first and the models second. That’s what we’ve learned from watching 30 years of model use in science.”

“I realize now that numbers are numbers. They really can’t tell you much about what’s going to actually happen. Sometimes you’re lucky, sometimes you’re not. We just happened to hit the jackpot, twice.”
