I have started daydreaming of a career change to geology. There are just so many unanswered questions and its not like space or physics were these questions are tinyor super far away. You can just walk upto a geologic puzzle and hit it with a hammer.
Ever heard of Geophysics? :) https://en.m.wikipedia.org/wiki/Geophysics
Not sure if my username gave it away or not, but I’m really into applied mathematics. I’m a physics major right now, & while I don’t immediately see myself studying this in grad school, I think that the physics of Volcanism/Plate Tectonics is extremely fascinating. It certainly looks at the history of the world through a very different lens, but I wouldn’t write it off completely!! The physics of our Earth is a beautiful, beautiful thing. :)
Geography is just physics slowed down, with a couple of trees stuck in it.

Unfortunately geology jobs that aren’t working for the oil and gas industries are few and far between.
