Dr. John N. Shive, Director of Education and Training at Bell Telephone
Laboratories, in about 1960, before the great split of the Bell phone
companies when the Bell Telephone Lab was one of the premier research
facilities in the world. (It is still good, but must make money.)

He produced an ~25 minute 16mm film called "Similarities in Wave
Behavior" and a booklet with the same name, copyright in 1961.

The original Shive wave machines, of which we have one, is far better than
the ones produced by Ealing and perhaps others.

So here is my story about the Ealing version:

When they first came out, we got one of the first dozen or so, and it did
not work because they suspended the spines from their centers so they were
in neutral equilibrium rather than so they would actually hang
horizontally. They flopped around and generally ended up tilted. We sent
ours back, and it took over two years for them to re-design it and send
the new one to us.

When they had the Summer AAPT meeting here in 1984 I was showing a bunch
of demo techs around and told them the story. Several of them (as I
recall 3 or 4) had purcahsed the things, not been able to get them to
work, and just set them aside rather than complaining and sending the
things back.
