Most scientists today are locked up inside the safety of their laboratories conducting experiments and demonstrating scientific laws with minimal exposure to danger. But Norwegian physicist Andreas Wahl is not most scientists.
In an attempt to demonstrate a certain Newtonian law of circular motion, Wahl put his own life on the line and rigged himself 46 feet up a warehouse. With centripetal force compelling traveling objects to follow a curved path and accelerating as they near a central point, Wahl should be in good hands.
As soon as a ball of weight tied to the other end of his line was released, Wahl was immediately pulled by gravity to the hard ground below. But with centripetal force to the rescue, the ball wraps around the crossbar where his line is and stops him just a few feet from certain pain.
