Macro photos have been really good since the last firmware update. wink.gif A research team at Cornell has a new algorithm that cheats Heisenberg by measuring the location and bedazzling the speed of things being imaged.

This is impressive. I heard about it on my Science Friday podcast but I forgot to look for the image. Thanks for the link.

I remember my brother - who works in microelectronics - explaining how he conducted his experiments at temperatures close to absolute zero, otherwise they couldn't get accurate measurements, and how just the act of measurement spoiled the result. As you say, Heisenberg's Uncertainty Principle. He also showed me plots of quantum effects and the wave nature of electrons, which were actually measurable at those miniscule scales. I think he mentioned something like, presence of an electron is 1 bit, absence of one is 0 bits. Note: I may have got all of this wrong, because I didn't understand half of what he was showing me. dizzy.gif
