My dalliance in geochemistry allowed me to see "beyond" chemistry; climate, specifically paleoclimate, shows the interaction and complexity of Earth's physical processes.
Anyone who has dabbled in prospecting, fossil collecting and rockhounding has that perspective, that along with astronomy, is what captured my interest in the sciences in my younger years under the influence of my grandfather & uncles.
My perspectives are much broader than the bare bones of what I have stated in this forum, most of which I prefer not to mention, but rather allow papers and substantive articles of others in the academic community to speak for me. It is useless for an internet personality to claim any credential and expect it to mean anything.
The web, I find, is a great leveler where ideas have to stand on their own more than on the personality or credentials of the speaker.
My "dalliance in geochemistry" means that I took a few grad-level courses in geochemistry and geophysics. I might've switched from my failed Ph.D. program in chemistry over to geochemistry, but I realized I liked making a living doing something relatively easy too much.
