STAR IN A JAR: THE PHYSICS OF SINGLE BUBBLE SONOLUMINESCENCEDr. Doug Clarke, now retired from Lawrence Livermore National Lab, will discuss the brilliant flashes seen in single-bubble sonoluminescence, and the role of their group's computer simulations in studying the physics.
Improving the efficiency with which we use energy is often said to be the most cost-effective way to reduce energy use and greenhouse gas emissions. Yet, such improvements usually lower the cost of using energy-intensive goods and may create wealth from the energy savings, both of which lead to increased ...
The atmosphere affects light propagation in many ways. Temperature and density distributions, aerosols, and ice crystals produce many interesting optical phenomena such as mirages, "sun dogs," the fata morgana, light pillars, and the green flash. Atmospheric turbulence leads to the shimmering of objects, the twinkling of the stars, and especially the distortion of laser beams propagating through the atmosphere. A fundamental ...
