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!

I’m tall. Most of the people in my family are tall. Does that mean my son will be tall? Turns out the inheritance of height is a lot more complicated than we thought. Scientists know that nature (genes) and nurture (environment) both play a role, but after more than a century of questions, we’re only just now starting to get some answers

Bottom line: Masks work. They are safe for almost everyone to wear, and the more people that wear them along with adhering to physical distancing and other strategies, then that's more lives we'll save. But there's still a lot of confusion and misinformation out there when it comes both to wearing masks and the actual risks of getting infected with COVID-19. In this video, I address a few of the most common myths and misunderstandings using scientific evidence. #WearAMask

00:00 Introduction
00:46 Myth 1: Farts vs. viral particles
02:20 Myth 2: Cloth masks can't stop viruses
03:25 Myth 3: Oxygen deprivation/CO2 poisoning
05:40 Myth 4: Toxins
06:41 Myth 5: I feel healthy so I don't need a mask
07:51 Myth 6: Masks aren't 100% effective, so why wear one?
08:34 Mask-wearing history
09:25 Myth 7: Government mask exemptions
10:24 Myth 8: COVID isn't a big deal
12:09 Conclusion

Why are trees and other plants green? Seems like a simple question. But the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, you’ll get to see trees like you’ve never seen them before. And these other-worldly images can teach us not only why trees are green on Earth, but what color photosynthetic life on other planets might be.

I’ve explained a lot of weird bodily functions on this show but there’s one that we haven’t covered that’s always confused me: Tickling. What are you for, tickling? What’s the point of you? Why do you exist? Why do you make us laugh even though we hate you? Let’s dig into our evolutionary past to try and find an answer.
