ptychography

Ptychography is like taking a picture but instead of just taking one picture, we take a bunch of pictures and use special math to put them all together and make one really clear picture. It's like a puzzle where we take a picture of one piece at a time and then we put it all together to make one big picture. This helps us see really small things and figure out what they are made of. Scientists use ptychography to look at tiny things like cells, atoms, and even things that are too small to see with our own eyes. It's like magic!
