Yesterday I had the pleasure of accompanying the freshmen class to Prater. Prater, a large amusement park, is home to the oldest ferris wheel in the world, or so I'm told. You may have seen the ferris wheel in a few movies, including The Third Man.
The weather was perfect for the freshmen to scurry around the amusement park calculating such things as velocity, accelartion, and G forces for various rides. They also enjoyed experiencing these things, and fortunately none of them tossed their lunch in the process.
