I am not a student, I own a company that designs electronic products. One of my engineers stumbled on your lecture on Tellurometers while researching a project we are working on. Since then I have learned a ton from you. Thank you for sharing your work and simple explanations. You are a talented instructor.
Good catch. Also, the buoyant (lower atmospheric pressure and whatnot) forces will dominate over gravity - a liter of air is 1.3g at sea-level, ~ 0.8g at 1km up. --> 0.5g error if measuring a liter of water i.e. 0.05%

Never thought of a balance as a null device. Very nice lecture, thank you for posting.
Great lecture series, but 1/3000 error in the gravity case is 0.03% not 0.3%!

PS, that does not detract fron the brilliance of Dan Gelbart as a teacher :)
