Creating Clouds

Nicole Sharp - September 29, 2017October 14, 2019

Despite their ubiquity and importance, we know surprisingly little about how clouds form. The broad strokes of the process are known, but the details remain somewhat fuzzy. One challenge is Keep reading

Creating Clouds

Nicole Sharp - February 17, 2017October 10, 2019

What you see here is the formation of clouds and rain – but it’s not quite what you’re used to seeing outside. This is an experiment using a mixture of Keep reading

Simplified Schlieren Set-up

Nicole Sharp - December 18, 2014August 19, 2019

Schlieren photography offers a glimpse into flows that are usually invisible to the human eye. With a relatively simple set-up–a light source, collimating mirror(s), and a razor blade–it becomes possible Keep reading

Shocking Instabilities

Nicole Sharp - August 27, 2013July 27, 2019

The Richtmyer-Meshkov (RM) instability occurs when the interface between two fluids of different density is impulsively accelerated – usually by the passage of a shock wave. The image above shows Keep reading

The Sound of Helium

Nicole Sharp - August 18, 2010June 24, 2019

Gases of different density are good for more than just physics demonstrations. They also affect the transmission of sound waves, thereby altering our perception of pitch. As fun as sulfur Keep reading

Floating on an Invisible Sea

Nicole Sharp - August 10, 2010June 24, 2019

Many gases may be invisible to the human eye, but that doesn’t make them the same. Sulfur hexafluoride is more than 5 times as dense as air at standard conditions, Keep reading
