Here's a great example of what we spend about half of Chapter 1 studying in physics:

I have a whole slew of scientists mad at me this week – and I will admit that I am pretty irritated back – because none of us cool rational analytical scientists can truly separate our emotions and our egos from the reality-based science that we do. In this current dispute, I get to claim the scientific high ground, at least. My scientific paper that just came out this week unarguably demonstrates that their scientific paper has some rather embarrassing errors.
