Professors Donald Ivey and Patterson Hume show how the over-all effect of a very large number of random events can be very predictable, using several unusual games to bring out the statistical nature of this predictability. They explain the predictable nature of radioactive decay in terms of what is shown. For more info on PSSC, its history, and films, visit http://www.afana.org/psscfilms.htm

Dr. Robert I. Hulsizer uses a cloud chamber and gold foil to carry out the historic Rutherford experiment which led to the nuclear model of the atom. He clarifies the behavior of alpha particles by use of large scale models illustrating the nuclear atom and Coulomb scattering.

Using the radioactive decay of cosmic ray mu-mesons shows the dilation of time in a filmed experiment which takes place on top of Mt. Washington, N.H. and at M.I.T.in Cambridge, Mass. Explains how data are taken to determine the time distribution of the decays of mu-mesons at rest. Determines the counting rate for mu-mesons with speeds of about .99 the speed of light which arrive on top of Mt. Washington and measures the number that survive to reach sea level. Deduces from the experimental...

Dr. Alfred G. Redfield performs a simplified Millikan experiment photographed through the microscope. Substituting standard spheres for oil drops, he demonstrates the effect of X-rays and the relationship of the charge to the velocity of the spheres. Professor Francis L. Friedman explains that charge comes in natural units that are all alike, and points out numerous changes of charge.

Professor Byron L Youtz uses a stream of electrons accelerated through mercury vapor to show that the kinetic energy of the electrons is transferred to the mercury atoms only in discrete packets of energy. Establishes the association of the quantum of energy with a line in the spectrum of mercury. Points out that the Frank-Hertz experiment was one of the earliest indications of the existence of internal energy states within the atom. Includes an epilogue by James Franck. A PSSC (Physical...

George J. Wolga shows why we believe in the unity of the electromagnetic radiation spectrum. He performs experiments which show that the radiation arises from accelerated charges and consists of transverse waves that can be polarized.

Dr. James S. Strickland shows how an electrolysis experiment enables us to count the number of elementary charges passing through an electric circuit in a given time and thus calibrate an ammeter. He explains that elementary charges in an electrolysis experiment are identical to those in a Millikan experiment, and demonstrates the random nature of motion of elementary charges with a current of only a few charges per second.

In the hands of another director, the inner-workings of a magnet laboratory could have caused a whole classroom to fall asleep of boredom. No so when Leacock was hired to produce this twenty-minute version of lab mayhem. Try this: six researchers in a lab at MIT in the late 1950's show-off the power of electro-magnets, and in the process, accidentally set an experiment on fire(Leacock says he did a retake without the fire, but preferred the immediacy of the fire sequence and kept it in). Or...

Explains how crystals are formed and why they are shaped as they are. Considers their actual growth under a microscope, how they may be grown, and the relation of these phenomena to the concept of atoms. From the PSSC Physics series. Blue Ribbon winner, American Film Festival. This film can be purchased on DVD and higher quality versions of the film can be purchased for stock footage purposes.

Here, manic Princeton professor Eric Rogers hosts, continually removing and replacing his eyeglasses, ordering around lab assistants --- he forcefully breaks a glass test tube in the hands of an assistant to demonstrate the inelasticity of water --- and furiously pounds equations on a blackboard (Leacock says the scribblings must have lasted 45 minutes, in what must be one of the more necessary cuts in the history of educational film.) Rogers finally conducts an experiment with a young girl,...

This PSSC film utilizes a fascinating set consisting of a rotating table and furniture occupying surprisingly unpredictable spots within the viewing area. The fine cinematography by Abraham Morochnik, and funny narration by University of Toronto professors Donald Ivey and Patterson Hume is a wonderful example of the fun a creative team of filmmakers can have with a subject that other, less imaginative types might find pedestrian.

MIT Professor John G. King performs an experiment in which light exhibits both particle and wave characteristics. He uses a very dim light source, a double slit, and a photomultiplier in such a way that less than one photon is in the apparatus at any given time. King points out that the characteristic interference pattern is pointed out by many individual photons hitting at places consistent with the interference pattern, and discusses the implications of this action.
