I am a 45 year Geologists working in Oil and Gas in Houston. I am not very good at advanced math, pretty much checked out at calculus, but I have always loved physics. I use fundamental principals of physics every day when developing arguments to support various depositional models. Physics is really the best first test to any interpretation of past physical processes on earth. I am joining today trying to figure out the force of a head trauma I suffered at 6 years old when a sail boat mast fell on my head. I guess I am to post the physics problem in a separate section so I'll go find that next.
