Like a well-trained dolphin, the miniature experimental submarine maneuvered docilely around the waters of California's Santa Barbara yacht basin. No propellers, no jets were visible along its sleek, 10-ft.-long hull, yet the sub was obviously moving under its own power, gliding silently at about 2...
Bow to Stern. In schoolroom demonstrations, an electromagnetic force is produced by passing electric current through a wire or other conductor suspended in a magnetic field. The current generates a magnetic field around the wire that pushes against the field of the magnet. In an electric motor, current flowing through...
The electromagnetic submarine (EMS-1) in Santa Barbara works on the same principle. Its storage batteries send current through a large coil wound bow to stern, inside the cylindrical section of the hull, setting up a magnetic field in the surrounding sea water. The same batteries send electric current through...
Convinced at last that a full-size sub was possible, Way figured that it was worthwhile to try a small version. Last year, while on leave from Westinghouse to teach at the University of California's Santa Barbara branch, he handed his senior engineering class a term project: the...
Schwinger received the Nobel Prize for Physics in 1965 for his work in reconstructing the equations of quantum merchants which govern the behavior of electrons and electromagnetic radiation.
