Len Ortenzi is a 20-year instructor who prefers to capture his student’s attention by showing them the wonders of science first-hand. So while other professors are explaining the physics of weight distribution and the nature of sound waves, Ortenzi is taking a nap on a bed of nails and shattering wine glasses with high frequency sound energy. His sometimes unorthodox teaching techniques make him a popular instructor on campus and have helped him land a spot as one of NASA’s Network of Educator Astronaut Teachers.
