ancient city of Teotihuacan (spelling?). In the background one can see the Pyramid of the Sun.
Gabor Simon, visiting Ph.D. student from Hungary, showing nice preliminary results on measurements of acoustic eigenfunctions using a phase-locked-loop technique, which he developed at NBI during the spring semester of 1999.
Kristian Schaadt, 1999. The setup put up a hell of a fight, but had to surrender when knifes were drawn.
Mark Oxborrow, 1997. Mark is preparing his favorite acoustic resonator for measurement.
