Thank you. Knowing makes all the difference! On my way to highschool one
morning (bus, past the newsstand to the subway), I read the about the
astounding invention of point-contact transistors. The NY Times article
included a technical discussion and an illustration. I read it several
times. When I got home, I made one. It was oscillating before supper.
Knowing makes all the difference.
