Vacuum Ultraviolet Lamp of the Future Created in Japan

MAPL-Ono-UV-Nagoya-JB.jpg

A team of researchers in Japan has developed a solid-state lamp that emits high-energy ultraviolet (UV) light at the shortest wavelengths ever recorded for such a device, from 140 to 220 nanometers. This is within the range of vacuum-UV light -- so...

Is the Power Grid too Big?

CHAOS-Newman-optimalsize.jpg

Researchers are asking whether there is a "right" size for the U.S. power grid; they believe that smaller grids would reduce the likelihood of severe outages, such as the 2003 Northeast blackout, likening the grid behavior to sandpiles: “Sandpiles...

Wind Energy: On the Grid, Off the Checkerboard

JRSE-Stevens-windfarms-resized.jpg

Researchers at Johns Hopkins University have developed a new way to study wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the...

The Spin Racket: Ping-Pong Champs Are Intuitive Masters of Fluid Dynamics

Curve balls may help a pitcher strike out batters in baseball; and some nasty spin can make an opponent sweat to return a tennis serve. But more so than in any other ball game, in table tennis – where the ball is so light and so small –dedicated...

Experts Available: Fluid Dynamics and Ship Experts Discuss the Science of the Costa Concordia

When the cruise liner Costa Concordia drew too close to shore near the Italian island of Giglio, a large rocky outcrop quickly sliced through the ship’s hull. While many questions about the dynamics at play during that disaster remain unanswered,...
