Measuring corneal radius with illumination
Since magnification is 0.0156, I have: m = -i/o 0.0156 = -24cm/o o = -1538.46 cm 1/f = 1/i + 1/o 1/f = 1/24 cm - 1/1538.36 cm f = 24.38 cm R = 48.76 cm However, when I look up the average corneal radius, the google results show ~5 mm. Did I do something wrong?- ewang

Why Does Adiabatic Compression Yield a Negative Work Calculation?
Nevermind, work is negative integral oops. I was staring at this for the longest time.- ewang

Why Does Adiabatic Compression Yield a Negative Work Calculation?
This is a relatively simple problem, but I'm not getting the right answer. For adiabatic compression, work on gas is positive, since work on gas = ΔEth and the adiabatic process moves from a lower isotherm to a higher one. Integrating for work gives: pV * (Vf(1 - gamma) - Vi(1 -...- ewang
