**need to add general "this is what we expect for {geo,cyclo}stropic balance" sections to both sections**
**need to add more of an intro**
**need to add more experimental details for both sections**
These are the results of Kristin Berry's (kree@mit.edu) and Roman Kowch's (rkowch@mit.edu) 2010 Balanced Motion experiment. Feel free to email me us if you have any questions about our results or would like to obtain our data to analyze on for your own analysis.

Data Analysis
This is an example of one of the particles we tracked and selected for analysis. Note that its radius steadily decreases as it spirals inward, as we would expect, but that its path appears to be slightly ellipsoidal and off center, which introduced error into our calculations.
looking at v vs r, we find that the particle's velocity increases as it gets closer to the center of the tank, as we would expect from conservation of angular momentum.
This shows basically the same thing, though less directly. As time goes on and particles move closer to the center of the tank, their velocities increase, consistent with conservation of angular momentum.
This was our first plot of theoretically predicted Rossby number with our experimental data. Note that the fit is terrible!
