Re: Glen Becks $9 online university 9 classes
THe closer you get to math, the more difficult it gets to apply political pressure as it gets harder to refute the studies. If you have a study a complex system (any research on animals or humans would fall into this), it becomes very easy to say you didn't account for this, or that, or the sample size isn't big enough, etc.
In Math and physics and computer science and alot of forms of engineering, you have a high degree of control over the system setup and can do pretty much what you want. And if someone disagrees, yu can just go run the same experiment.
In addition, most people aren't affected by the research in the hard sciences in a direct way.
