You Use Quantum Physics to Smell

Your nose uses quantum tunnelling to smell! This crazy conclusion comes from the latest interpretations of the evidence about how our smell receptors detect odour molecules. This video summarises the two models of smell: shape theory and vibration theory, and concludes that you need both to explain how we smell. #quantum #biology #DomainOfScience Get the maps! https://www.dosmaps.com Here's my Instagram:   / dcwalliman   Patreon:   / sciencemaps   The main reference I used for this video was "Life on the Edge" by JohnJoe McFadden and Jim Al-Khalili. Which I highly recommend, it is very well written and contains some brilliant science explanations. The field of quantum biology is utterly fascinating. https://www.amazon.com/Life-Edge-Comi...

To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors! 1. I misspelled Planck's Constant and wrote Plank's constant. Silly me! Thanks so much to my supporters on Patreon. I hope to make money from my videos one day, but I’m not there yet! If you enjoy my videos and would like to help me make more this is the best way and I appreciate it very much.   / domainofscience
