I'm currently in a probability and statistics class, and while I can appreciate the concept of trying to keep tabs of large sets of data, I just can't get past the fact that if you actually run the experiment, the results will probably (ironically) come out differently that what you calculated. I thought science was supposed to be about precisely predicting the results of an experiment. Or is probability more about how an infinite set of experiments will turn out? For this reason it is my least-liked class at the moment... just wondering if anyone else feels the same way. Similarly, how can Neilson Media (sp?) take 5000 TV boxes, and calculate television ratings for a nation of 300,000,000? I understand the concept of representative sampling, but if they get the "wrong" sample of a certain group, it would mess up the whole study. And yes, I know the quantum area of science is filled with probability. I hope humanity one day discovers how to precisely predict sub-atomic phenomena.
