If everything around us is made of atoms, why can’t we actually see them? From ancient philosophy to quantum mechanics, electron microscopes, and the strange limits of human perception, let’s explore one of science’s deepest questions: what does it really mean to “see” something?

Be Smart explores science questions you didn’t even know you wondered about. It is hosted and produced by Joe Hanson, PhD. We post new videos all the time, so please subscribe! If you enjoyed this video, hit the ‘like’ button, leave a comment, or watch another of our videos!
