The article is inspired by Functional morphology of gliding motility in benthic diatoms, a paper published in Proceedings of the National Academy of Sciences. This is my first time writing an article like this. Welcome to leave your comments/suggestions/criticism! Imagine a microscopic glass (silica) box in the water. It has no wheels, no legs, no jet engines, and no cilia. Yet, the moment it touches a surface, it glides, turns, and reverses smoothly as if powered by invisibl

To me, microscopy is mostly about microorganisms. So to talk about microscopy, I have to talk about them first. When I was an undergraduate studying Environmental Science in China, one of my favourite courses was Environmental Microbiology. I still remember the afternoon we sampled water from a pond on a bridge, and explored the sludge under a microscope. I still have a photo of a rotifer on my phone — back then I didn't know its name, but I thought it was impossibly cool. I
