As I cruise around the internet, I sometimes run across something that refers to the Copper Country in the oddest places or ways. Today I was On Boing Boing and they had a story that referenced the Tamarack Mines Experiment. I had never heard of it so I looked into it. Apparently J.B. Watson suspended plumb lines into the Tamarck mine in an experiment that showed they were farther apart at the bottom than expected (they thought they would be closer). This is a famous experiment in physics, but new to me. If you want to learn more, here is a link. (http://www.lhup.edu/~dsimanek/hollow/tamarack.htm) I am amazed at the important people and events that occurred during mining's hey day in the U.P. Sometimes I think they were just more ambitious than us. Of course, they did not have TV, the internet, or the Green Bay Packers to distract them!

Michigan Tech has some articles on there website about the experiment. Here is one that is from the Mining Journal at the time.
