Atom Monday

Ever wonder what an atom looks like? These building blocks of ordinary matter are a million times smaller than a strand of hair, making them impossible to see, even under a microscope. That is, until now. David Nadlinger, a Ph.D. student in University of Oxford Department of Physics, just won the top prize at the science photography competition organized by the Engineering and Physical Sciences Research Council (EPSRC) for his groundbreaking image of an atom.

Titled Single Atom in an Ion Trap, Nadlinger’s photograph shows a single positively-charged strontium atom suspended in an electric field between two metal electrodes. For scale, the two needle tips it dances in between are just two millimeters apart. A close-up crop of the image lets us see this small dot of light, and is an incredibly unique way to see this tiny particle.

    Algiers to Timbuktu is 1,500 miles, close enough.

    So Mr. Xi wants to be chairman for life. I guess we should all practice saying “Yes, Chairman Xi!”

    Ok, up B Street in the roadway, over to C Street via the Newman Center sidewalk and up to the CUB for an errand took 20 minutes. Then on to the east but via Wilson Road. Just after the meat lab south on Olympia Road extension to Grimes Way. Then back to the Hillside Cafe via usual routes makes a total of 58 minutes so far today.

    Got a voice mail from 1800 772 1213 today

    Said it was Microsoft Security, and my security certificate had expired, and I must call them or my computer may fail to work
    I don’t have a computer, so I gave them Carol’s number instead

    Just kidding, Carol

    No weather again today, just bright sun all day long. Jill and I went to get our taxes done. We haven’t had to file for a few years now, don’t have enough income to merit paying federal taxes. We went to see Bob to get our State of Michigan taxes done. We get a homestead thing, which worked out to be $450 this time. I asked Bob the tax preparer why it was more this year than last which was $384. It’s based on your income and if you make less that something-or-other, you get a refund from your property taxes? I may have got a little more because Bob died in November and his SS was taken back out of our bank.

    Jill paid my preparation fee again. She’s a good girl.

    Don’t know if I told you this story. After Bob died, a week or so later I looked at our saving’s account on-line and Bob’s last SS payment had vanished. It was taken back by the SSA. I expected that. Bob drummed it into my head about depending on what time of a month he died and the money arrived, I might have to give it back.

    I got a letter two weeks ago that I scanned and tossed on the piano. When I looked at our account on line again a week ago, the money they took back from Bob in November was back in our account along with my monthly SS money. I got the letter off the piano and actually read it, sure enough, they said according to their records they owed that money to Bob and were going to put it back and if I thought that was wrong, I should call them. Call them? HA! They know what they’re doing, I sure don’t. So yeah, I’ll take it!!!

    The SSA runs like a top and god-forbid it is EVER privatized.
