The Ultimate Macro Image - A Single Atom

  1. Be sure to read the comments after the article to understand, or not understand, what you're actually seeing. Isn't quantum physics fun?:)
  2. I saw that. It doesn't get much more macro than that, does it?
  3. horizon’s a bit iffy.
  4. I forwarded this to my nuclear physicist wife for comment. We'll see what she has to say. I would note that what we are seeing is a re-emission (NOT reflection) of photons (light particles?) from the atom, not incident light, so it is a bit of a stretch to say we are "seeing" a single atom. It is not terribly different from what we see in a cloud chamber, which is condensation caused by the passage of sub-atomic particles, not the sub-atomic particles themselves. In both cases we observe the physical effects of the small particles on their environments, but not the particles proper. Still, a fascinating and engaging image...
