Nobel Laureate and Laser Inventor Charles Townes Passes

An anonymous reader writes Charles Hard Townes, a professor emeritus of physics at the University of California, Berkeley, who shared the 1964 Nobel Prize in Physics for invention of the laser and subsequently pioneered the use of lasers in astronomy, died early Tuesday in Oakland. He was 99. "Charlie was a cornerstone of the Space Sciences Laboratory for almost 50 years,” said Stuart Bale, director of the lab and a UC Berkeley professor of physics. “He trained a great number of excellent students in experimental astrophysics and pioneered a program to develop interferometry at short wavelengths. He was a truly inspiring man and a nice guy. We’ll miss him.”

      This is why I loathe the euphemisms for death. I realised this when the man I sailed for (for over a decade) died. It wasn't a massive surprise, but still a shock. To most of us it was the end of an era. What struck me was that most of the others talked about "him passing", whereas I simply said " he died", and I caught a couple of glances when I said it like that.

      As another example - my sister was with friends (in a marina on a friend's boat - we like our sailing) and a guy walks down the companionway and said "X is gone". My sister stops talking (people come and go from marinas all the time), and then continues talking. The guy says " are you stupid or what - X has died ", making her feel like a shit.

      People die, it happens, but dispense with the euphemisms - there's nothing to be gained from them.

      Well, it IS nonsensical - I mean, by what means should an electron be able to go from point A to point B without acquiring the necessary energy to get over the energy barrier? Granted, the uncertainty principle means there's a chance it could "borrow" the energy temporarily, but that's a random event. What happened is we have a controllable way to tunnel electrons.

      These days we use electron tunnelling every day - the NAND flash chip relies on the floating gate to hold electrons and influence the transistor's parameters which is how it stores bits. And to get those electrons to the gate, we merely bias the transistor in such a way that electrons magically disappear and reappear on the floating gate, without shooting the electrons through the insulation.

      We don't get why or how they do it, but we can exploit it.
