In 1696 Isaac Newton left Cambridge ‘ his home and workplace for thirty five years ‘ to move to a new job in London as Warden of the Royal Mint.  It was supposed to be a sinecure, a no-show job.  It wasn’t.  Instead, Newton found himself in charge of remaking England’s entire...

On March 3 – 5, 2011, Stephen F. Austin State University in Nacogdoches, Texas, will host the Spring 2011 Joint Meeting of the Texas Section of the American Association of Physics Teachers, the Texas Section of the American Physical Society, and Zone 13 of the Society of Physics Students. The...

In this talk I will present two ultracold atom experiments, one exploring 6Li-40K Fermi mixtures and the other quantum degenerate gases of strontium. The first experiment has the goal to create a new class of strongly interacting many-body quantum systems. After careful characterization of the interspecies...

The arrival of the transistor revolutionized the electronics industry, allowing devices to be smaller, faster and more robust. However, the abandonment of vacuum tubes for solid-state devices also marked the move from ‘clean’ ballistic to ‘messy’ diffusive conduction. Subsequent...

Fractals are patterns that repeat at many magnifications.  These intricate patterns are found throughout nature, ranging from clouds, rivers and lightning through to our brains, blood vessels and lungs.  Due to their prevalence in nature and their growing impact on technology, fractals have assumed...

The flow between concentric cylinders with the inner cylinder rotating has been studied by visualization techniques. Velocity power spectra have shown that the flow is described by two characteristic frequencies before it becomes chaotic; the first frequency corresponds to traveling azimuthal waves....

Our experiments on doubly periodic wavy vortex flow show that the second spectral frequency corresponds to a modulation of the m azimuthal traveling waves. We use spacetime symmetry to classify the possible modulation patterns and to predict a basic period ? such that in the frame rotating with the...
