…but it’d actually be interesting to find out whether or not cows can detect magnetic fields. Not least because, if cows can detect magnetic fields then the next question would be why cows can detect magnetic fields. Generally, living creatures have abilities for a reason. The reason may no longer apply in the modern era, but there should have at least been one to start out with.
I dunno. I don’t think that abstract research in the sciences is a waste of time, per se. It’s often a waste of money, or at least an inefficient use of limited funds – but then, you never know.
