Abstract Title: Two Advanced-Lab Experiments for the Thrifty Physicist
Abstract: Over the past two years, four AJP papers have resulted from innovations in Emory's Advanced Lab.  I highlight the two experiments that can be done at almost no cost:  a simple optical probe of transient heat conduction, and oscillations of a water column beneath trapped air.  The heat-conduction experiment requires only a laser, a stopwatch, ice water, and any transparent liquid or solid; the laser beam's deflection increases and then mysteriously decreases as the transparent material is chilled from below.  The water-column experiment requires only a clear tube, a bucket of water, and a digital camera; the water column's oscillations mysteriously reach their lowest frequency when the tube is about half full of water; higher frequencies are observed when a smaller or larger fraction of the tube contains water.  Both experiments use simple equipment to illustrate mathematically complicated behavior--mysterious behavior that defies intuition and motivates inquiry.
