I recently heard there was a Foucault's Pendulum on the UT Campus. With two science loving boys and one science loving husband, I figured Christmas break was the perfect time to check it out!
The pendulum is located in the Development Building on UT Campus -- But not the UT Campus you think of. This building is located across I-35 from Main Campus. You've probably passed the building a hundred times on the elevated portion of I-35. On the east side, a brown building with a red cylinder in the middle. The red tower contains the pendulum - and has since 1985. Who knew??
So, parking isn't an issue. There are plenty of parking spaces, allowing you to easily access the pendulum. Go inside the building, take a quick left, and you will see the pendulum in the stairwell, along with a small plaque explaining its purpose.
Having a PhD physicist in the family, we had all the explanation we needed. But if you aren't already familiar with the pendulum, I suggest you take a few moments before you visit to 'get' the concept. Wikipedia has a nice animation explaining the gist of it all. Essentially, the pendulum, designed in 1851, was the first simple test to show that the earth was rotating.
We all had a great time running up and down the stairwell, checking the pendulum out. The floor has small rectangles marking off the hours; We even stopped back after some chores to see how the pendulum had moved.
