In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy for the amount of cosmic rays. This is because 10Be is produced, inter alia, by cosmic rays in the atmosphere. Being a congenitally inquisitive type of fellow, I thought I’d look to see just how good a proxy 10Be might be for solar activity. Now most folks would likely do a search of the literature first, to find out what is currently known about the subject.
I don’t like doing that. Oh, the literature search is important, don’t get me wrong … but I postpone it as long as I possibly can. You see, I don’t want to be mesmerized by what is claimed to be already known. I want to look whatever it is with a fresh eye, what…
