In one of BBC's Horizon programmes, Jim interviews David Deutsch. It may have been in the last episode of the "Atoms" series. What Deutsch says is that IF you accept the principles of the world's most accurate predictor of physical reality--quantum mechanics--in microcircuitry, lasers, GPS, the generation of starlight, the creation of heavy elements,etc, then you must accept these same principles as they play out in human biology (biology in general). You can't have it only one way.
BEST Talk!!! So intrinsically explained . Thank you :)
You are...,
as young as the moment,
and as old as the universe,
too small to see everything,
big enough to be connected to it all,
one of many while being many of one,
outside my body,
inside my mind,
a reflection,
to my,
"I"
Jason Decker, it’s interesting because when you said ‘one of many while being many of one’, you are actually made out of recycled organisms of other dead organisms (dead living beings *cough* dead humans/animals *cough*) since organisms takes about 1000000000000000000000000000000000000 years to break down, estimated.
thank you, Jim. that was amazing. words can't describe how much i awe this great presentation. one more time, THANK YOUUU
Amazing talk. Passionate, messy and educational. Loved it
Reductionism vs Emergent Properties. I'm a fan of emergent properties.
Well done, Jim. Good talk.
I love both physics and biology. Based on the amazing finds he is sharing it seems like a field I will be interested in.
General Turner same here
I’m literally like every known category of Science. Anyone else here?
Which field did you end up going?
That was a very short 18 minutes! Jim never fails to impress as a public communicator of science. It's just a pity he had to gloss over things so quickly in the short amount of time he was given.
Really very beautiful lecture it has a great connection between QM and biology this can be comprehended according to quantum tunneling in some animals and birds
Very much impressive talk.
I found this most intriguing. As my professional goals are to use stem cells to treat, prevent, and cure bipolar and schizophrenia this may have pertinent influence in achieving these goals. I will be following their progress more closely.
Your professional goal sounds amazing! good luck x
How’s it going?
To me Quantum physics explains why the logic which seems to be integral to our vast universe is not really necessary to live and survive in this grand illusion. At ground zero, picture is absolutely fluid and responds differently to each observer. However, when interaction grows, a common set of logic, rules or faith comes in play and starts controlling the group of objects or life.
what a presentation!!! even i can understand it. thanks.
After decades of scoffing from the old scientists on the role of QM in organisms (esp the brain), this will truly be the dawn of a new era of understanding nature
Awesome explanation 👍
wow. so much informative:)
Very interesting. I had come across instances of QM influencing biological systems before (in plants) but not the stuff mentioned here by Jim. Must read some more on this.
He explains how cytochromes detect blue light during migration of European robins, but I missed how that is an indirect way to measure the Earth's magnetic field. I was also hoping he would talk about how QM improves the efficiency of photosynthesis in plants.
Having looked up NMR spectroscopy, I think I now understand how physicists can say that electrons spin. Though they have no physical features or structure that can be used to determine if they are spinning, they create a magnetic field as if they were spinning. Have I understood correctly?
If anyone has an alternative explanation, I'd love to hear it.
Thanks for the video as it is quite excellent. It is interesting, however, that Jim is like the astronomers in that he does not know when to use "among" vs. "between." Something can only be "between" two items.
im just like HOW CAN BIOLOGY advance the field of physics
BIOMIMETICS
I think you're right
There are somethings that physics just can't explain
I don't think electrons can spin at all. If they are fundamental particles, then they have no internal structure or physical features or protrusions, and so the very idea that they can spin doesn't make sense. I think probably that's just a term physicists have given to a certain attribute of them, in the same way that quarks with colors and flavors obviously don't have such features in the conventional definition of the word.
Looks very nice. But I simply wish to send this video to someone more qualified than myself...
In 1963 Per-Olov Löwdin published proton tunneling as another mechanism for DNA mutation.
hydrogen atoms are protons
No sound
dont try to change your apparence she is perfect ......
A lesson!
Jim Al-Khalili's closing comments miss the point but astrophysicist Paul Davies makes up for it in his article: "Exposing cancer's deep evolutionary roots" Physics World July 2013.

+Maireid Sullivan Cancer is hoax come to life because we deprived ourselves from various natural elements. Why would FDA ban vitamin B17?
+Alex Kostko Etcetera! :)
+Alex Kostko Because it is toxic
what's inside an electron or proton?
Quarks.
i was being sarcastic. What's inside a quark?
sam tauckoor chicken. At least it tastes like chicken.
According to the string theory, inside the electrons are 1 dimensional strings and inside protons are quarks and inside quarks are 1 dimensional strings
sam tauckoor god
The most baffling in this speech was cancer related proposition. It just flushed the previous contribution down the rabbit hole.
+Alex Kostko Almost the entire talk was on the possibility quantum tunneling playing a role in gene mutation. Cancer is gene mutation. Not sure what you find baffling. The idea is to look into this area of science "quantum biology", now that we have the technology to do so. "The rabbit hole" is a metaphor for the conceptual path thought to lead to the true nature of reality, & being infinitesimally deep and complex, venturing too far down is not recommended for the weak minded.
+CaptianKeyz I find a lot of language in the talk is less logical as one should expect from quantum science (a lot of adjectives and linguistic turns. This talk confirms that "all problems in the world are in the language".
Alex Kostko True. It may be due to the audience he is speaking to, but I can't confirm that. I will look into it to see if he has a more comprehensive lecture out there.
Alex Kostko The Standard Model of QM is indeed straight up "Alice in Wonderland " check my comment. I am saying Ed Witten as popularised by Brian Green and Michio Kaku might have something to say about QM.
biology have many quantum aspects just took the planck constante some see it as a limit but it is what authorize you to form new molecules the spirit you have controlate every input and output of your body if you are a buddha so you can control the creation of new feelings
It's wise to combine quantum functions with molecular biology. But for this working relations, life's diversity becomes immosibility. Quantum functions must play a role in creation. It's weirded information sharing system, I believe, helps the universe in its creative pursuits. show less
+Vaidyanathan Purushothaman Well said! Quantum physics will help us to comprehend this creative process of our universe. Perhaps, even answer bigger questions that we cannot even begin to contemplate, just yet. I like the way you think. Enjoy the rabbit hole, my friend.
Try Jersey Shore
you are on the wrong way with D.n.a. she do not explain all the changes of the body she is like the code source but if you focus on the source you will loose a huge part of the code ......
you know why quantum is right cause =Phy(x) and =1/Phy(x)
it is meaning when you dont have an idea where is the particule you have the same probality to find him than the selfprobality and the second that if you know where is the best probability to find the particule you have more chance to find it .......
wow you're actually right I think lol
il aurais fallue 100000 plus de livres si on utilisais pas le formalism ........
I shouldn't even bother, but you should get your physics right before talking rubbish regarding the uncertainty principle. It's not about precision measurements, it's fundamental because its a mathematical consequence of wave-particle duality. It's there because that duality has been proven to exist. It's a fact.
Btw, everyone: Watson was declared an unperson in scientific circles, because he said human races exist and that there are differences between them.

What on earth is a muslim atheist? Islam isn't the colour of someone's skin.
Interesting information badly delivered; the guy was all over the place and didn't fully explain anything.
Yeah he said a lot and didn't say anything. Thumbs down
I was referring to the presenter, not you.
Fabiozon I respectfully have to disagree. My colleagues and i understood it all
100% agree with +EmceeWhitey and the presenter... ♂♂♂
+Fabiozon Give him some slack. He has limited time up there, & is a physicist not a public speaker. I understood everything & did a little research on what he left out.
90%of what he said is a lie. one example is tunnelimg is nothing like what he speaks of...
he's an atheist
he doesn't understand Quantum Mechanics and physics in general...wrong interpretation of experiments
Boring...
Too much talking and I'm getting nothing out of it...
