Pfft. I don't know where you got your degree, but on this planet, 1+1=1.999 and sqrt(2)^2=1.999.


Wait a second... let me check... oh, I see we're on planet Earth. I guess you're right. 1+1=2 and sqrt(2)^2=2. Thanks for the correction. []

Manufacturing tolerances can be a third stop or more, anyway, due to things such as aperture activation variance. (I.e. you set f/8, but the camera accidentally goes to f/7.5 or f/8.5 because the mechanics aren't precise enough.)
