Musings on optics, physics, astronomy, technology and life

I hope all my U.S. readers had an excellent Thanksgiving yesterday, and I hope you all have an excellent weekend, whether you are getting an adrenaline rush out of the Black Friday sales or you are trying to dodge commercialism altogether.

This year we got a reminder that the eye surgery known as LASIK descended from some experiments on Thanksgiving turkey leftovers. I already knew about this, of course, but it’s great to hear that the tale will be going into the OSA Centennial History Book so that future generations will know the origins of this procedure, which has enormously benefited some of my highly nearsighted friends.

Yesterday afternoon, part of Greenbelt, Maryland, was hopping as Comet ISON passed close to the Sun. NASA hosted a Google+ hangout from Goddard Space Flight Center, just a couple of miles from my computer desk, and I was watching along and retweeting things on Twitter. At the time it really looked as if the comet had vaporized entirely when it grazed our local friendly star, but perhaps part of it survived the close passage. I guess that makes ISON a “zombie” comet! Hey, zombies are extremely popular these days.

This year, for my Thanksgiving dinner with friends, I made my from-scratch creamed corn with cornstarch instead of wheat flour, because a couple of the folks at the dinner table are gluten-intolerant. And I hurried home to do a Skype interview with a researcher in Australia. Yes, we used today’s optical communications technology to talk about tomorrow’s optical communications technology. We live in fascinating times indeed.
