To be fair, it is such a ridiculously small object that they're photographing that just to get a picture of it out of focus is a miraculous feat imo. Hopefully sometime in the near future, we can get an in focus picture. I think it's awesome that we have come this far in the first place, for sure, though!
Perhaps you'll find this interesting...I know I did.TerpZ now that is bad to the bone!!!!!!!!!!!!! Thank you for sharing. That is the most interesting thing I have seen all day. What else do you have? I can hardly believe you can actually see the rings like that. Wow!
it's a (3 minute) video of a tooth. Several microscopes of varying intensities were used to keep zooming in on the tooth until it gets to an eventual zoom of 30,000,000 times.
