The difference here I have seen so many times in my life, I just thought I would share the lesson with this classic discussion of odds. The set up goes like this: youhave a tossed a coin and it has come up heads one thousand times in a row. What are the odds it will come up either heads or tails on the next toss? Joe Sixpack will typically say that it should come up tails, because it has come up heads so many times, tails is due. The Scientist, trained in mathematics, knows that what it has done before has no influence on what the coin will do next. In fact this situation is often used to illustrate odds when results occur in streaks. The Engineer doesnt care so much about theory, all he cares about is what he sees happen when he does one thing or another, and he knows that the next result will most likely be heads because we have obviously been flipping a flawed coin.
