Physics, Sex and the Reason Why
Physics is like sex: sure, it may give some practical results, but that's not why we do it.

If you replace the sexual in Sexual Selection with Physics and reverse the order you get Selection Physics. This makes no sense as far as I can see, yet the select act of "doing" physics is a pleasurable act worth doing on a daily basis. Will it make you blind? Probably not, so do what you do!
