Just finished the last class in a Nitrox / Enriched Oxygen advanced certification diving course. You would have loved it, HRMG. I was in the room with two chemists and a nurse as we are working out all these complex mathematical equations for pressure, residual nitrogen, nitrogen + oxygen mixes at .32 O2 vs. .36, ata/bar and how it affects dive time, residual nitrogen, etc. HUGE formulae for things that can be done with dive computers but, hey, my certification instructor is old school. Wants us to do it by hand. (depth x nitrox mix) + (pressure x residual nitrogen) + atmosphere divided by 1.4. Here the chemists are rattling the numbers off the top of their head while I am thinking Please Remember My Dear Aunt Sally with a calculator in my hand (math folks will get that reference) HAAAAA!!!
I almost had to take off my shoes to help with the math, but, hey, I passed!
