I have a box filled with "calculators" (slide rules) that do a lot more
than +, -, x, , & take sqrt's.

Years ago I sent a box of them to India. Know any other group that
could use some?

A couple years ago, I began teaching introductory astronomy courses at a
local Catholic university (the University of St. Thomas of Houston,
Texas). Each of their two intro astronomy courses (solar system and
stellar galactic) has a lecture and laboratory component. I was teaching
the lab component with several students who did not bring calculators to
assist in the mathematical part of the lab when I remembered a box
labeled "calculators" in their store room. I went to fetch the box and
bring it out to the students and found it was full of slide rules and a
few abaci (more than one abacus)! One electronic calculator circa 1978
was among the collection but it did not work...

Tom,

I think what I found is a later version: it doesn't show any sign of
glass
having been used as the recording medium and the rails are closer
together.
The tuning fork ("C" 128 Hz) is driven by an electromagnet.

To see an example of the free fall apparatus that Cliff mentions, go


to




http://physics.kenyon.edu/EarlyApparatus/Mechanics/Free_Fall/Free_Fall.h
tml .


This dates from the 1920s -- not very old at all...

Cliff -- you break my heart when you disassemble this piece of
apparatus!

Best Regards,

Stephen,

I have been doing serious scavenging in the attic. There is some
wonderful old stuff up there. I am grabbing on to whatever looks good



and



isn't museum stuff. I just finished building a "new" pile driver,



parts



of which came from two Young's modulus apparatus and an old free fall







experiment (really old: it used a tuning fork and a stylus to leave
timing marks on a wax paper streamer).

My guess is most of the stuff will be tossed.

Cliff

Quoting "Wallin, Stephen R" :




Don't lose those dandy historical artifacts in the attic. Was UNL
first
physics graduate school west of the Missip.?

I just got this note:


Dear faculty,

The Society of Physics Student has been put in charge of taking
inventory for the physics department. The information gathered will




be




used to help prepare moving into the new building. In the next




couple




of
weeks members of SPS will be contacting each one of you individually
to
sit down and catalog your specific equipment. This process should




take




no more than an hour of your time, and it would be nice if this




could




all be done in a timely manner. Thank you for your cooperation.
