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!

A so-called “heat dome” is pushing temperatures across Europe to extreme levels. Deaths have already been reported in France and the UK, as authorities warn of growing risks.
DW correspondent Lisa Louis reports from Paris on how people and governments are coping. And climate researcher Peter Thorne, Director of ICARUS, explains why this heat is so unusual — and what it tells us about climate change.
The UN calls it a “brutal reminder” of the climate crisis — and experts say such events could become more frequent.

#PPOD: This mosaic of images taken on Oct. 6, 2008, by NASA's MESSENGER spacecraft shows an impact crater on Mercury named Hokusai. The crater has an impressive system of rays that extends more than about 1,000 kilometers across the planet. 🧪 🔭
