Mr. Hinton's talk entitled, "Square Orbits," explored the unusual orbits that can result from a regular two-dimensional arrangement of like charges. In particular, arranging four like charges in a square can, under certain circumstances, lead to a fifth charged particle having an orbit with square symmetry. Likewise, arranging five particles in a regular pentagon can result in a sixth particle orbiting in a pentagonal path, and so forth. Michael plans to submit his work to "The Physics Teacher" in the very near future.
Ms Spaeth spoke on, "Rotationg Bacteria Using Optical Tweezers with an Elliptically-Shaped Focus." In the talk, Ms. Spaeth details how she and faculty advisor Dr. Heidrun Schmitzer used laser light trap and then rotate living shigella bacteria.
While they were attending the meeting, Mr. Hinton, Ms. Spaeth, and faculty member Dr. Stephen Yerian took time out to visit Dr. Stephen Tobin (Xavier physics class of 1988) at the Los Alamos National Laboratory and tour the town and facilities.
