My intent has always been to create physically and mathematically correct animations, accompanied by explanatory text, that illustrate complicated phenomena involving waves and vibration in a manner that aids student understanding. Now that I'm back at Penn State, teaching graduate level acoustics, I'm continuing to add to my collection of animations. Sometime around 1998 or so I began writing webpages and adding them to this online collection.
For the next 16 years (1995-2011) I was a physics professor at Kettering University and continued creating animations and using them as educational tools for the courses I was teaching about waves and acoustics. student in the Graduate Program in Acoustics at Penn State. I started using Mathematica to create animations to help me understand and visualize certain acoustics and vibration phenomena in 1992 while I was a Ph.D. The links below contain animations illustrating acoustics and vibration, waves and oscillation concepts.
