The above video explains the workings of electron microscopes. A beam of emitted electrons is guided and shaped into a focal point by a lens of electromagnets. There can be multiple electromagnet lenses to further focus the beam. Eventually they can narrow it down to resolving individual atoms. It was not clear to me how the image was captured, but then again, most of the details of it all passed well over my head.
It reminded me of the 1957 movie The Incredible Shrinking Man. In it the hero, Scott Carey, is exposed to a radioactive cloud while out sailing. This causes him to start shrinking a few days later. As he continues to get smaller his shrinkage starts to ruin his marriage (insert your own joke here) and, when word of his condition leaks out, it turns into a media circus. He gets small enough to move into a doll house. Unfortunately for him, his pet cat spots him and decides he would make a tasty appetizer. In escaping the cat, he falls down the stairs into the basement and is too small to climb back up. He monkeys with a mouse trap to get some cheese to eat and is interrupted by a giant spider -- well it is a giant to him -- and has to battle it for the cheese. Below is the ending, where he climbs through a screen and ponders his fate. It is a good, albeit very odd, movie.
