Description

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.

I have also made a version available for educational use which you can find here: https://www.flickr.com/photos/95869671@N08/33581664495/in/dateposted-public/

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-Coming-Quantum-Biology/dp/0307986829

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 Im 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. https://www.patreon.com/domainofscience

Also, if you enjoyed this video, you will probably like my science books, available in all good books shops around the work and is printed in 16 languages. Links are below or just search for Professor Astro Cat. They are fun children's books aimed at the age range 7-12. But they are also a hit with adults who want good explanations of science. The books have won awards and the app won a Webby.
