This short video clip (less than three minutes) on heat
convection is a subset of the Full 25 minute clip. That
was the only 1956 motion picture of Prof. White lecturing
that we could find. The initial frames are a photo of
Prof. White in the actual TV Physics classroom, but the
video clip was taken from a contemporaneous film clip
(for TV) made in the same year, 1956, on the same
subject, physics, and addressed to the same level of
audience, high school. The video clip shows a TV program
called Science in Action that was produced in 1956 at the
California Academy of Sciences in San Francisco.
