First day!

[cjsmith]

I survived my first day of classes! Today was shorter than usual because the first chem lab is all about counting out flasks, doing paperwork, and signing out equipment.

Today in school I learned that kinematics is the study of motion, I learned not to eat in the student center, and I learned to avoid trying to park between eight and one.

Motion vs. causes thereof.

As well as I understood mechanics dating back to high school physics, I never was clear on that distinction until taking Atmospheric Dynamics recently. We don't talk about mass at all, just the equations for motion. Everything is put in terms of "per unit mass" so we don't have to worry about it.
