Researchers at Northwestern University are studying superconductors using a hybrid magnet weighing 34 tons and standing 22 ft tall at the National High Magnetic Field Laboratory in Tallahassee, Florida. The huge magnet improves the imaging of high-temperature superconductors so much that William Halperin, a professor of physics and astronomy, saw the cores of vortices, which he describes as tiny electrical tornadoes swirling in the superconductor's copper oxide compound. His findings include evidence of an electronic Doppler effect. The professor is hoping to improve resolution of MRI machines used in hospitals. For more information, visit www.northwestern.edu.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
