DEPARTMENT HISTORY |
|
It is interesting to note that in the catalog(ue)s, separate mention is made of the course offerings of the Mathematics Department and of the Physics Department (which also taught the mechanics classes) even though, with only a small number of exceptions, a single group of faculty was responsible for the entirety of those courses up until the mid-1940's. That is, academically the two departments were presented as separate entities though administratively they were one. Early research included unpublished experimentation with the newly discovered x-rays. The faculty learned to make their own tubes for this work with public demonstrations in the spring of 1896, less than one year after Roentgen’s 1895 article. While it is unclear what research was done, Fisher had significant "burns" on his hands which he attributed to early x-ray exposure since, in Fisher’s words, "nothing was known in the early stages of the destructive action which x-rays have on animal tissue." The Tamarack Mine Experiments
The first pendulums were made with #24 steel piano wire
and 50 pound cast iron weights and were hung 4,250 feet down shaft #5.
The period of these pendulums was 70 seconds. The weight actually
stretched the wire about 15 feet. For some measurements the weights were
placed in oil or water to help damp the motion though this was
insufficient to completely stop the motion.** They typically used
multiple measurements of the oscillating pendulums "as in the method of
determining the zero point of a balance by observing the oscillations of its
pointer," rather than waiting for the motion to stop. * Both Watson and Slock had Engineer of Mines (EM) degrees from the Michigan Mining School: Watson in 1895 and Slock in 1896. ** the extra buoyancy due to the oil caused the wires to shorten about 25 inches, a result which was considered "rather striking."
