BS Detection - A Very Interesting Problem

I remember how important it was. We had to use just using dimensional analysis, we had to establish some proportionality between quantities involved. And so being able to come up with that, and another technique is order of magnitude estimation, which a lot of people don't really know how to do, and that gives you your first BS detector. Yeah. So that gives you an order of magnitude and you can look at the results you're getting in compared to that and see if you have any hope of being in the right ballpark. Dealing with astronomical quantities. Yes, and astrophysics is where you get a lot of that, yes.
