Video conference with Technion, May 9, 2006.

A short documentary of the history of the subminiature vacuum tube. This 16 minute film was produced by the MIT Museum with funding from Raytheon in 1986 for the MIT Industrial Liaison Program. The producer and director was Seichi Tsutsumi of the MIT Industrial Liaison Program. The film may be freely used provided credit to the MIT Museum is supplied.

Inspirational lecture delivered on June 24, 2008.

30min lecture delivered by Prof. Beretta at the Junilee 40th Symposium on Mathematical Physics "Geometry & Quanta" on June 25, 2008 in Torun, Poland, held in honor of Prof. A. Kossakowski on his 70th birthday.The lecture summarizes the main mathematical features of the nonlinear dynamical equation proposed in the 1980's by Prof. Beretta and recently "rediscovered" by various authors, to decribe the nonunitary evolution of density operators along the direction of steepest entropy ascent (that is, maximal entropy generation) compatible with energy conservation. The density operator is what describes the state of a system within quantum theory. More on this subject is available at www.quantumthermodynamics.org where several not readily available papers can be downloaded.

A long length of wire is suspended horizontally between the poles of a magnetron magnet. When a large current from a 12V storage battery is passed through the wire, the wire jumps out of the field. When the direction of the current is switched, the wire jumps the opposite direction.The magnetron magnet in this demonstration was originally used in MIT's groundbreaking research developing radar during and after World War II. Microwave emitting cavity magnetrons need strong magnetic fields, which were often created by powerful permanent magnets like the one seen in this demo.

Two flexible wires are suspended vertically. The wires are conected in series or parallel to a 12V storage battery. When the wires are connected in series and power is applied they will repel each other; when they are connected in parallel they weill attract one another.This effect is due to the magnetic fields created by the charge flowing through the wires. When the wires are in parallel, the currents in each are going in the same direction and thus attract. In series the currents are going in opposite directions and repel.

A magnet with a very strong magnetic field is held in place on an aluminum disk. The disk is attached to a motor powered by variable AC current. When the disk rotates, the magnet will levitate above it due to eddy currents generated in the disk. With the disk spinning, these eddy currents form to oppose the magnetic field of the magnet, making it levitate. When the motor is turned off, the magnet falls back to the disk.
