    Remarkable Photo of a Single Atom Wins Science Photography Contest

    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.

    I think a question remains, is the dot of light we see the actual size of the atom or is the image actually larger than the atom? For example, when you see a "twinkling star" some of that twinkle is an atmospheric distortion, not an actual part of the star.

    It said the needle tips were two millimeters apart, that's almost 80 thousandths of an inch, (39.3x2) a human hair is more like 5 thousandths of an inch, fine hair about 2 thou...

    So I suspect the actual atom is much, much smaller than what appears in the image.

    Thx
