A quote from an article published by Smithsonian Magazine: http://www.smithsonianmag.com/science-nature/phenom-200801.html?c=y&page=1 I know this article is almost a year old, but I have never heard of this before. I also find this pretty amazing and seems to me that some one such as myself should have read this was possible from somewhere already. So...how exactly is this done, does anyone know? Is this something that can be predicted by quantum electrodynamics? I always thought light was just the creation and destruction of photons, like the feeling of cold just being heat transferring from your body. Are they just taking photons and just stopping them in matter? And one more thing, does the probability of determining the position of an electron greatly increase at near absolute zero temperatures?
