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. If you would like to buy a poster of this map, they are available here: https://www.redbubble.com/people/dominicwalliman/works/25781802-your-quantum-nose-how-smell-works 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/ Domain of Science forum: https://www.commonlounge.com/community/7df58003ee83407fbef41fe842c7014f 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 Here are some other links you can look at if you want to find out more: https://en.wikipedia.org/wiki/Vibration_theory_of_olfaction https://phys.org/news/2011-03-quantum-explanation.html http://www.physics.org/featuredetail.asp?id=83 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. 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.

"because we can smell in the dark" is such a great line out of context
Your method of visually presenting everything does an amazing job of hammering in concepts and better understanding it all. Keep it up!
wrr
you should make a map of engineering. I feel like it'd be really interesting
YES!
OH YEAH
OBVIOUSLY YES
You should've mentioned that the both Vibration and Quantum tunneling theory explains why we can't smell relatively cold objects.
I hadn't even thought of that! That is very interesting.
I can honestly say I learned something completely new today.
Great video, thanks!

map of biology, chemistry, and medicine please.
Oh medicine please!
👋 Hello I am a request:
'Map of Philosophy' por favor
:)
MinionNoMore carneades.org already have one ;)
Unfortunately says "under construction", and I believe nothing can be as beautiful as Dominic's style (:
I have*
Idk why i think this comment is so adorable
joao skate it wasn’t as clear as these videos tho
That also means taste is effected by quantum physics, it's been stated quite a lot that heavy water tastes sweet.
Also with mirrored molecules, it should make a tiny difference how they are since the atoms outside of the benzene ring interact with each other in a very small manner. Or as you said, they just do both.
Yeah I'm unsure. There is a large smell component to taste, so it could be that heavy water actually smells different, but tastes the same. I think taste receptors work differently to smell receptors, but I'm going to have to look that up! :D
It would be very interesting to find out! Anyhow, amazing job on your videos man, fell in love with this channel instantly. ♥
@Domain of Science Smell and taste actually do use the same kind of receptors. Thanks for the video.
what software are you using for edit this video ?
wait... newborn baby smell? What? Is that like a fresh-out-of-the uterus smell or something else? How long does it last? So many questions
hahahahah
Thanks for the laugh out loud!
baby powder
@Domain of Science This was awhile ago, but YES, baby smell is a Thing! Bigtime. It was a great example, and wonderful to see a baby pop up in your map, lol.
@Sophie Somerfeldt Thank you! :D I was starting to feel like a weirdo for saying it lol
Make a biology map! great videos man :)
Yes!
I read the title as "Quantum Noose"
Fantastic video, interesting as always. Keep it up!
Ohh my god ... I have been searching about Smell for months now and did not understand a thing .. This video is godsend !!
Love the video, thanks! I wonder how you would explain varying smelling ability. For example, dogs can smell seizures coming - presumably chemical changes in the body prior to a seizure. But, even staying within the human species, there are people with more adept senses of smell. More receptors? Ability to sense different vibrations? Interested in your thoughts. Thanks again - love the mapping.
From my research here are a few bonus facts: Bloodhounds have a 40x larger olfactory epithelium, and so physically more smell neurons, plus a larger area of their brain dedicated to smell. Bears have the best noses, 7 times more sensitive than a bloodhound's and can smell a carcass 20km away. Within humans the sense of smell does vary, but I don't know what causes this variation but my guess would be more or fewer receptors.
One of the most interesting videos i've ever seen on YouTube 😍
The map of economics!
One of the only pure science channels on YT where I can follow everything and always learn something new and lasting by the end. Thank you!
What a nice thing to say, I'm very glad you are enjoying the videos!
I love these videos, the design is sooo good and learning something new at "the scienctific way" is very entertaining. Good luck!! Greetings from Chile!!
wow, nice video, i been wondering the same thing for so many years. Glad I found this video.
Always an intriguing watch, thanks!
This video made me unbelievably happy. :D Anyone else? Please, more videos on quantum biology! ;)
I found this video very informative and well explained. Thank you for sharing. : )
Your channel is kind of a gold nugget, which I've found recently.
Great work, waiting for more!
I looooooved this! This is awesome! As As 7Buns mentioned - great visualization.
I love your videos! can't wait to keep learning from you! im sure a lot of us would like to know your video making process!
Brilliant. Absolutely brilliant work! Love it!
Could you post sources on this (and future videos) please!
The main source was chapter 5 of Life on the Edge: The coming age of quantum biology by Jim Al-Khalili and Johnjoe McFadden. It is an awesome book summarising the latest in quantum biology. Fantastically well researched and written.
Got surprised, the video shows "Plank's" instead of "Planck's"!
I'm a stupid head. Thanks! :)
Whose here from the Jim Al-Kalili book (life on the edge: the coming age of quantum biology)
I never posted a comment before but I feel I owe you this much. Great presentation!
Thank you for an interesting video. I appreciate that you provide references in the description.
soo interesting, thanks for the video!
I really like the high level science content of this videos and you have a very simple way of explaining things.
brilliant channel!! I can't stop watching your videos! Great job!
I learn something new with every one of your videos. Keep it up!
"Duterated"
I misread the title as "quantum noose", I've never clicked on a video so fast
Amazing as always !
hello! I loved the video, I'm currently in 12th could you suggest me from where should I start studying quantum physics,from basics. I'd really appreciate thank you.
Nice video. Would love to see more about our senses, how we taste, see, etc.
ah yes, I, a high school student, smell new-born babies everyday
No backing music in the future please. I find it distracting from your voice, like faint static noise on a radio channel.
Please more of this! The way of explanation is just so soothing... and conveniently, it's about quantum stuff!!
Great video, but I think you misspelled planck's contant when discussing the energy of photons.
Anyways, keep up the good work!
"inelastic electron tunnelling spectroscopy" sounds profoundly interesting. I'll have to look into that. thanks!
Your videos are phenomenal! You make learning difficult subjects so easy : )
And the old wise saying goes unabated, "He who smelt it, dealt it!"
I think now it's time to make a poster for the "PARTICLE PHYSICS" and in the last topic of this poster will be Higgs Boson..!😎🇮🇳

If you don't know why you are subscribed to this channel, I just changed the channel name from DominicWalliman, so you probably subscribed after my Map of Physics or Map of Mathematics videos. Even though I changed the name, everything else is the same, and I'll be doing more of the same kind of videos! Sorry for any confusion.

next topic electricity map with batteries , types of solar electricity , machanical electricity , etc imagine and
relate electricity to create , store , use in form maps

Domain of Science I get that you referenced the book that you used in this video but I think it would be really nice if you could provide free online sources for further reading. Obviously we can all just go and look this up on our own but I'm lazy and the time you spend would save time for everyone else too.
Domain of Science - 2017-04-05
Hey Peter, yeah you make a good point. I'll add it to my to-do list and see if I can find some good online resources. Thanks!
