H≡[(1/a)(da/dt)]=(8πG/3) ρ + λ/3 - k/a
Yes! I figured out how to use math symbols and Greek letters in my journal! Oh, happy day!
Ahem, sorry. For those not already thoroughly confused, the above equation is an equation of motion for the universe, derived from Einstein's field equations, where H is Hubble's constant, a is the cosmic scale factor, ρ is the density in matter and radiation, λ is the cosmological constant, and k is the curvature constant.
I am one happy person with apparently far too much time on his hands! Woo hoo! Go me!

No, I don't mind you asking...at the moment I work at Radio Shack, which is not really physics related, but it occasionally affords me the opportunity to use some equations regarding electric circuits. It honesty is not what I saw myself doing with my degree, but it's fun and it pays the bills, so I can't complain. I would, however, very much like to go back to school and get a teaching degree so I can confuse teenagers with this stuff in the same way it confused me when I was sixteen.
Yeah, some of the people who work for Radio Shack are knobs...some of them are in the head office, some are in the stores. Your situation sounds typical...I probably would have looked through the manual myself, but only if you hadn't already done it - that way I wouldn't look like a total idiot.
