Meet William (Toby)

I am very fortunate to have a lifelong experience with Physics. I was born in 1946, and my father, William J.

I grew up in his lab while in the WWU Campus school, watching his demonstration of a Tesla coil behind the hall door, powering a light bulb on the hall table. I was inspired at Bellingham High in math by my calculus class teacher.
