Wow, I'll take that as a compliment
I work at a company called Cyoptics, in the final test phase of a product that modulates a laser beam at 40,000 megahertz shoving that beam into an optical fiber that will hold that signal for over 100 Km without the need of a repeater. Before that, I was a road warrier for Varian and Associates, for 20 years on the road in the Ion Implanter devision, but in 98 they sold that division back to Extrion in Gloucester Mass where it started out. Ion implanters are used in the semiconductor industry to impart conductivity (between that of an insulator and a metal, thus the term SEMI conductor) by 'doping' pure silicon with some specific ions, the big three being Phosphorous, Arsenic and Boron, which lets you choose between positive charge carriers and negative charge carriers, either way, the ions when imbedded in a silicon crystal lattice act as way stations for electrons, scattered at about 1 % or so of the silicon. Silicon, having valence bonds, don't like to share their electrons so the ionic guys get put into the crystal lattice, taking up the space formerly occupied by a silicon and they get stuck in place just like traffic cops, to the electons, MOVE ALONG, NOTHING TO SEE HERE, MOVE ALONG...
Quite a bit of very interesting physics in the ion implanter.
But that is old history now. Did three years in Israel, took my whole family there at company expense, they paid for the kid's school, 3 kids, and rent for the house and paid the rent on a car. It was a nice time for sure. That was in Jerusalem at one of the Intel plants there. There are two there now, BIG money makers for Israel.
