Researchers show light can add drag to fluorescent carbon nanotubes in water, revealing quantum friction that may help control nanoscale transport. (Nanowerk News) Light is expected to heat particles ...

"Behind the power curve" describes flight at low airspeeds (below L/Dmax, the minimum drag speed) where induced drag dominates, making the aircraft "speed unstable" and requiring high power to ...

The Boeing 747-8 is the largest, newest, and most aerodynamically advanced 747. The aircraft has a wingspan stretching 224 feet 7 inches (68.4 m) and features redesigned airfoils and raked wingtips ...
