Over the course of last year I was doing a rather cool experiment in YU for an Experimental Physics course. I built a macroscopic tool for one-dimensional phonon simulation. This involved hanging lots of (23) steel cubes (in prototypes they were balls) from long strings, vibrating them at different frequencies, and then measuring the amplitude and phase of the vibration of the final block.
I will be presenting the results of this experiment (in the form of a poster) at the PASI conference that I'll be attending next week in Argentina.
You can download a (113kb) PDF of this poster here [pdf], if you want to be able to actually read what's there.
Also, check out this writeup on the conference from YU's webpage [link].
