I recently got to sit down with physicist and science communicator extraordinaire Prof. Brian Cox. Did we talk about black holes, the Big Bang, or alien worlds? Nope! We talked about biology. Specifically, what is “life” and how did it begin? You might not expect it, but looking at life through the lens of physics can teach us a lot about why interesting groups of atoms like you and me exist.

Life, man. What is it even?
Idk
A Game which Humans don't understand.
That's why started studying biology for my Advanced level examinations.
What's life? I am not even sure what I am
Life is what happens to you while you are making other plans
This channel is a key example of why publicly funded media is still so important in the digital era. The right people given the right resources can do amazing things and grow to provide so much more value to society than what was invested. Keep up the amazing work!
Yet, populists across the globe want to defund it :(
Why don’t YOU make it, if “the value is so much more than invested”?
Sounds like you’re not being honest…..
@@Americansikkunt Imagine being a troll and sucking at it lol
@@Americansikkunt what a dumb question, not everyone is an educator at heart or wants to make videos for UA-cam 🤦🏻♂️
@@slcpunk2740 I’m just saying, if it was Objectively more valuable, everyone would be investing!
Also, public funded = MY money. You don’t think I have a say in how it’s spent??
Meanwhile this evening I did a (bad) impression of Prof Cox on stage to a few hundred people. And even though it was so dodgy, everyone knew who it was as he’s such a legend. Nice to hear him talk about Sagan, as many see him as a modern version
I also did an impression of him. It was cut from the video for being so so bad
Whoa, only 10 likes and one reply?
I looked up Brian Cox after watching a guy doing impressions, one of which was him. In doing so, I find this video from just yesterday/today, which I would probably have eventually seen in my suggestions and watched anway. Cool intersection there.
Jo is awesome, Brian is incredible but you at Medlife Crisis is amazing
@@besmart I'm sure the people on Patreon would love to it.
Brian Cox is an absolute legend in the UK. Personally I love how he's always smiling. What a wonderful guy, you can feel his passion.
The man is a fraud
My feeble neighbour is also always smiling.
Omg same!!
I'm in Canada and I think the same as you. I love his shows about the the earth and universe.
@@Engineer284 really? Lol
On a crisp December morning in the heart of Oldham, I found myself navigating the bustling streets, bundled up against the winter chill. As I meandered through the town, sipping on a warm cup of coffee, I spotted a familiar face among the crowd - none other than physicist Brian Cox.
There he was, strolling along the cobbled streets, seemingly lost in thought. Seizing the moment, I mustered the courage to approach him. "Excuse me, Dr. Cox?" I said, half expecting him to be too engrossed in the cosmic mysteries to notice a passerby.
To my surprise, he looked up with a warm smile. "Yes, that's me. How can I help you?" he replied, his accent unmistakably Northern.
We engaged in a delightful conversation, discussing everything from the intricacies of the cosmos to the charm of Oldham during the festive season. Brian, with his affable demeanor, shared anecdotes about growing up in the town and how its character had shaped his curiosity about the universe.
As we continued our walk through the winter-kissed streets, Brian's passion for science and genuine interest in our conversation created an unexpected camaraderie. We paused at a local bakery to warm up with some freshly baked treats, and amidst the aroma of pastries, our chance encounter turned into a memorable morning of shared stories and laughter.
Before parting ways, Brian left me with an inspiring thought: "Every corner of the universe has its unique beauty; you just need to take a moment to appreciate it." And so, on that cold December morning in Oldham, I not only met a brilliant physicist but also gained a newfound appreciation for the cosmic wonders hidden in the ordinary moments of life.
Thanks for sharing your encounter meeting with Brian Cox, it was a lovely anecdote to read after watching this video. It would be a privilege to have the chance to converse with him on natural laws and physics matters, and it was heartwarming to read how approachable and affable you found him to be.
Such a eloquently and beautifully written, interesting story. Thanks for sharing, I believe it's my favourite youtube comment yet.
How lucky to meet him! There’s so many things I would want to talk to him about if I had the chance
And you didn't smoke a doobie with him?
How absolutely wonderful. He always has such amazing insight and seams like a delightful person .
If you're lazing around, you consume less energy, you're making the universe disordered at a slower rate. So next time someone calls you lazy, tell them you're just postponing the universe's demise.
I think you missed about 12 minutes of this video lmao
Hilarious
@@scy1038 wdym, the video talks about how you existing is hastening the heat death of the universe, however insignificant it might be
Mind blown
Chaos theory?
He said, "what we learn in school about what is life is totally insufficient in describing what it actually is." how true.
And in the same breath, he will also tell you that the complexity of life is just a matter of "chance" but will not describe the various steps necessary for that to happen.
Sanjosemike (no longer in CA)
@@sanjosemike3137 That's because they don't know what life actually is.
I learned most of what was discussed in this video at school
Good point!!!
When I was young I read a book called..The origin of life..I think..it said all this stuff and more.. being very naive at the time I was really expecting some incredible revelation. But like this video I was told nothing. Book ended with some theory about life originating in outer space. As if this information was in some way answering the mystery. He sticks to the script and will not entertain some theories that are now gaining traction
I'm impressed how these people are staying sane while dedicating their lives to such complex questions. I'd go crazy by the time i'm reaching 30
Other’s take great comfort, relief, wonder and inspiration dedicating their lives to these scientific professions
Gosh I’m glad you say that because I thought I was the only one. I would be lead to an existential crisis 😂
Professor Brian Cox has a wonderful energy, he is candid, full of curiosity, joie de vivre,
compassion, passion - he is so alive - and his passion and all is contagious….
Thank you…..
What a joy to see Professor Cox on, he's such a personal hero of mine.
Why? Hes creepy and puts opinion as fact... just because someone has an accent and can speak properly doesn't mean what he says is true or valid.
Mine too
@@prototype8137 Prove any one thing he says is not true or valid.
And I don't find him creepy, not sure why you do lol
@@prototype8137 you forgot Rock star.
@@prototype8137 Maybe give a source material that shows he is genuinely creepy, otherwise that's just your own issue.
I swear I get goosebumps everytime he tells me to stay curious. In my mind I'm like "I will Joe. I always will"
I think about this all the time and it has made me realize that nothing really matters and I choose to let go of many of the things that I once dwelled on and worried about. I now know how lucky I am to exist at all and I will be positive and grateful and enjoy all the small things for my short time observing this universe.
Its not true to say nothing matters there is evil in the world and this statement makes it less important to protect the good
only cowards say this. all of the great minds discovered things because they wanted to get to the end of the question, not throw it away and say "nothing matters i am living on a rock", also, that view towards life is obnoxious, as things do matter, life does. dont be close-minded.
@@sel5595 what I meant is that I have decided to let go of so many of the things that brought me great sorrow and mental suffering. Of course there are many things that do matter but to realize that our time here is finite, helps us to understand what is important and what is wasted anguish. I should have worded it differently because of course some things do matter.
My dad introduced me to him in high school and I have created a huge love for his shows and all he researches. Sure I don't understand it the way he does but he definitely makes complex lectures be more easily understood by people who don't major in scientific fields. Xoxo
I am a 29 year old female who greatly appreciates people in the world like him
if there is a girl who interest with this object, ill date her
@@benynyomin5012 but will she date you tho?

You sir, are a superlative teacher! And so is Professor Cox. This has been one of the most fascinating interviews and UA-cam presentations that I have seen. But then, I’m an old man, an old medical doctor of a man, who has had the pleasure of experiencing many good and great teachers in his lifetime. And learning new things, for me, remains one of my greatest pleasures. And this border/ conjunction between the life sciences and the physical sciences is one of my greatest fascinations. I am so very glad that I found your channel and subscribed to it.
"... learning new things, for me, remains one of my greatest pleasures." Hear, hear! My life's motto is "When you've stopped learning, it's time to die." Fortunately, for me, learning is the single greatest aspect of living.
Much respect for keeping that passion for learning alive. I hope I never lose it, myself.
Ironically, this is not the first time that I've been told that I'm hastening the demise of the universe.
Are we (and life generally) really? Yes, there are cellular metabolic pathways that hasten chemical processes. But in the big picture all those chemical potentials have been put there by gravity mostly through our sun (and a tiny bit of other stars’ demise when creating transferic atoms in supernova). Our sun shines on life and the lifeless. The lifeless heats up and emits infrared. The most life can do is delay the retransmission of infrared and maybe emit it at longer wavelengths. Or burst into flames and retransmit in shorter wavelengths. Totalled up life is just a few chemical pathways that dipped its toes in the deluge of energy coming off the sun.
Hi Mike, take care of yourself. You are an absolutely unique combination of atoms and molecules occurring at a very significant time in our history when our presence on this planet is at risk due to global warming. We need all hands on deck, helping to make good choices so that our extraordinary species can continue along with all the other brilliant creatures. So your planet needs you, Mike. I hope you can enjoy your life while also making your own unique contribution.
Blame your personal faults on Putin. I do.
@@tracesprite6078 your life is meaningless and without purpose.
You used to date her too, huh?
“You’re radiating disorder in a cavalier fashion”. What an amazing quote!
When you think of where you were before you were born, it will give you an idea of where you are going after you die.
Not me. Im still fearing my consciousness will survive and my childhood brainwashing of hell will kick in. I need parts of my brain deprogrammed so this fear goes. Philosophers Doctors and Physicists and Hindus who believe in God or Reincarnation scare me no matter how much i tell myself God or eternal consciousness is bullshit.
Brian Cox is one of my favorite science communicators. He has a way of speaking about science and the universe that is so profound and poetic.
"As a fraction of the lifespan of the universe as measured from the beginning to the evaporation of the last black hole, life as we know it is only possible for one-thousandth of a billion billion billionth, billion billion billionth, billion billion billionth, of a percent" - Brian Cox
Yeah, let's ask a gate keeping tool like dimm witted Cocks, what life is..
To then make it even insufferable by this other tool saying his accent makes it better and "a little unfair".
You know why he, nor any other tool in this silly game they play, can't even begin to grasp that thingy called consciousness?
Because they're scientific Materialists, that deny 'God' (or whatever you want to call it) to have you eventually see their scientific Materialism but finally only the State as the only authority..
#FeedTheMarxistMassesTheirPoison
Ironically, consciousness and life, become obviously simple, from and Idealism perspective.
He speaks alot but his whole 'string theory' was just a waste of time.
That's not poetic, it's merely numerical stats ... the opposite of poetic.
Cox is a cheap Sagan impersonator because he worships sagan
It seems inherently unlikely that I am prodding a little screen to generate these words - which your copy of a wet kilo or so understands. Just saying.
Back when I was in highschool, we had a biology teacher (best teacher i ever had in every way) who asked the same question. He said we aint gonna do stuff from the books that day and just chill out and try and awnser this question. We where doing the same checklist and indeed quickly found exceptions. The way he did that particular class was amazing. He had 30+ annoying 15yo paying attention for 50 minutes straight. Making us try and discuss it with eachother. We usually were a load and obnoxious class but when we had Biology we paid attention especially that day. Sorry for the long useless rant. Had a flashback that took me back 13 years 0-0
All worthy
It isn't useless.
That's beautiful. If you can still talk to that teacher, do thank them and let them know how much they have impacted you.
Just curious . Did you pass in your biology class? Did you take it on further in your education. It's great to have a general discussion about the subject and that can be fun. But you need to also learn the nuts and bolts of the subject and that requires work which may not be so much fun.
LIFEThe principle of life or living; the animate existence, or term of animate existence, of an individual. As to earthly, physical life, things possessing life generally have the capabilities of growth, metabolism, response to external stimuli, and reproduction
If there's such thing as favorite scientist, Brian Cox is my guy. I love him so much. Every time I see him on the net I know I'll learn something great and I'll feel better because of his amazing smile and the obvious passion for his work. He's my comfort person. ❤
This was a great show. I was pretty much aware of all the facts, but these guys ordered them in an interesting way. Like life does.
Life did not emerge on its own.
Really enjoyed this episode Joe! Great topic to discuss with Professor Cox.
"We are a way for the Universe to know itself." - Carl Sagan, of course. The scientist with the heart of a poet.
Excellent discussion with a favorite physicist, Professor Brian Cox. I could listen to him all day. Thank you, Be Smart, and PBS, for the thought-provoking video. Subscribed.
He was right to. You have to resort to poetry when speaking of what Life actually IS. You can use science to explain how it manages to exist in the/this universe; but we are no closer to (and maybe further away from) understanding the incredibly weird organizing force since chemistry and biology got involved.
@@carlodave9 Sagan didn't even have a clue about the reason and purpose of the universe.
The Universe being self-conscious….idk
@@TheBorwig What are you if not an extension of the universe itself?
@@luismangiaterra1031 That's because there is no real "purpose" in the philosophical or religious sense. Life is a cosmic accident.
Why isn't a content like this more popular? This should be absolute essential 😮. Mind-blowing indeed
More than 1M views is pretty popular all things considered
Wonderful interview. I can safely say if I were to bump into Prof Cox in the street I’d be geeking out like crazy, wanting to ask him so many things whilst at the same time feeling wholly inadequate for his time and talents.
He is not able to explain life purely by means of physics.
same
Obviously, life cannot really be explained by physics alone.
Is this about D-Ream?
These two brains were definitely not able to explain life by physics alone.
I absolutely love Professor Brian Cox, after watching his TedTalk about a year ago I watched as many videos of him as I could and he has incredibly increased my interest in physics and astronomy! Thank you for the great video!
Have you watched all his BBC work?
Something funny I just noticed. Aside from looking sort of alike both Brian Cox and Shigeru Miyamoto seem to almost be incapable of speaking without smiling. Being experts in completely different fields both just seem so curious and enjoying what they do. What a joy to listen to these guys and just have them around.
Id love to see a genuine sit down conversation between you and Professor Cox, would definitely be an interesting watch
I love watching videos like this. Being inspired and then forgetting everything 3 weeks later and watching again!
So “non life produces life” …. This has never been demonstrated nor can it be replicated . Therefore these hypotheses are not scientific ,
"How do we posses consciousness?" is a question that still blows my mind
consciousness is just the next stage of information storing and processing isn't it?

Same. Consciousness being pure energy that we somehow contain but not really control. So weiiiirrd.
@@tarancehill651 consciousness is not energy, however it is a process that requires energy like any process and emergent property.
Thanks to computing.
Brian is a very wonderful explainer. Breaking down very complex answers into language we not so complex people can understand.
Ask him how or why enough carbon exists in the Universe for life to exists? I will save you the trouble. He has NO explanation for it. Ask him about the chance elements of chirality. He can't explain that either, even if he knows what it is.

there is something about brian's voice that is like morphin, everything is gonna be all right when you hear it, everything is greater than we are and you just give in... fantastic voice! fantastic guy.
I loved Cosmos. My kids were pretty young at the time that show was on TV and its time slot was rather late at night in Western Australia. My children were so fascinated by Carl Sagan's presentations that we had to allow them to stay up way past their bed time and what they didn't understand became such fun family discussions And so many years later my niece studying medicine at ANU in Canberra was lucky enough to attend Brian Cox's open air event at the university.
Great discussion, thank you!
I'm a non-parent (and admittedly Scrooge towards kids) but your comment is absolutely beautiful. Thanks for sharing!
Must be smart kids.
Jeremy England would make for a GREAT follow-up interview.
From the introduction to Quanta's interview:
. Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.
“You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said.
England’s theory is meant to underlie, rather than replace, Darwin’s theory of evolution by natural selection....
I had the same thought! Hopefully that can be organised soon.
As a follow up, a philosophical standpoint on life is want I want like an exurb1a video. As told in the video, it's upto the poets to define life🙂
@@randlker2152 ah, but what defines a poet?
This is an excellent broadcast!!! Very intelligent!!! Love it!!!!
I would love to have an hour of Mr. Cox talking. Uninterrupted.
I think a key component of the definition of life has to include the ability to propagate information with changes. Crystals can grow, things can propagate structure and information, but I think to be "alive" in the sense that we think of, the ability to change and adapt to promote continued propagation over time is a must. Reactions that are indifferent or incapable of doing so are definitely not alive.
Don't forget that Linnaeus nearly classified crystals using his system for living things.
@@suelane3628
🤨He did?
Thanks I've been feeling quite existential today, this is perfect.
what saddens me the most is the fact that we'll never know what our race is capable of after a million years or more in the future 😢😢
nothing like a little existential thought to make you feel alive.
Truth is the only kind of 'perfection'.. spaceandmotion
What you mean by "existential"?
Why people get existential Crisis? Seems like weird thing to me... People say why are we here? Because we are, by evolution over millions of years
What's the meaning of life? Objective meaning is survival, subjective meaning is what you want it to be
Not very hard questions...
Thank you!!!
I once asked my biology teacher in 9th standard that what is life? he said anything which do reproduction, breathing, movement etc, which was a definition given in our book but what I really meant was how some non-living things together creates life , so I again asked the the same question in more deep way and guess what, our teacher and our class representative stood and said same definition to me again, making me look like a fool in front of whole class and as an introvert it was not good for me but it didn't bother me much , as I thought that all of them just accept whatever is told to them even teachers without questioning and knowing how things actually works in world or they just don't want to(as they are dumb and just spending there life) and they just don't know what to answer to my question..
After that i didn't't bother to ask anything to anyone and find my own question's answer myself which is satisfying to me..
When sadhguru talks about life, evolution etc there are many people like your teacher who troll him using textbook definition and call him a scam.
Your teacher was worried in making sure you knew the answer to what would be in the exam, not satisfying your unrelated curiosity
Now this is gonna be a great vid. I always love listening to Brian, his documentaries are undoubtedly some of my favourites.
It's a video that makes me hate the existential imperative.
@@osmosisjones4912 well, you fell under the illusion because you detected a pattern of some sort, but seeing through the illusion just means you saw the "true" pattern, you saw a different pattern, where did objectivity come in?
For example, I saw a video of a cardboard cartoon crocodile sculpture, if you liked at it from the front it looks like a 3D crocodile, from the back it looks like an inverted collage of cardboard
From one perspective, an image, from a different perspective, a different image
There isn't an objective perspective, you can view it from multiple angles, no angle is "correct" thats an opinion not a fact
@@osmosisjones4912 We can always count on you for a stupid take.
@@Gibbypastrami To add to that the way another person perceives that optical illusion is going to br different. Maybe you and I see an animal, but they see a plant. Both are valid because you can explain to the person "Look at these angles and colors, see the plant/animal now?" And if you look long enough, you'll discern a second image out of the first and csn alternate between them at will.

Timeless wisdom and hilarity in one film.
How did I miss a video with Brian Cox in it!?!!! He's one of my favorite Physicist.
They are always sneaking in without UA-cam realizing that I want these videos IMMEDIATELY😆. Brian Cox is the GOAT.
Keep on thinking..keep on experimenting.
I got a degree in biology and am going back to get a degree in engineering and this episode made me have a nerdgasm
I know how you feel
I had one of the others this morning and similar to what Brian was saying I had disorder, in the tissue box department
I have a degree in engineering but would like a biology degree.
@@osmosisjones4912 no they are not
Biology is very simple. Go into a lab and make a living, reproducing cell from the raw chemicals. There is just one little problem. Nobody has ever done it before. How did it happen by random chance? (I have a degree in Biology.)
At this point in time, Physicists have yet to explain what part of the atom causes gravitation. We know matter causes a curvature of space-time, but we do not know why it occurs or how it is related to the other fundamental forces of nature.
I love how Brian Cox comments on Pluto’s planetary status, “I don’t care.”
I love Brian Cox and his amazing energy for science and teaching. He has such a beautiful poetic way of describing the universe and is ways of life and destruction.
Great interview! Thank you for this!
I can't remember if I knew you were a doctor of biology, but that's super cool! I'm always excited to find when people really studied on a subject can bring energy and knowledge in such a way that a broader audience can enjoy the subject as well.
Joe, You are a National Treasure. Thank you for all the wisdom you bring to us.
Great, insightful discussion!
No better topic, and a great person to talk to. Great show.
@9:25, Brian just explained the rankine cycle in two sentences. For someone who is a chemical engineering person, that was really crazy
I love how bunch of bipedal monkeys existing on chunk of rock revolving around a star in an seemingly infinite universe trying to answer most fundemental question in the universe.
If you’re referring to humans, we’re closer to apes, not monkeys.
Easy way to tell: monkeys have tails, apes don’t.
I LOVE this video; in fact anything Briantalks about is interesting to me. GREAT program; lets keep this one....
It’s amazing to listen two genius sharing information about the origin of life and more
Love anything with Brian Cox in it.
I learn so much from him!
You have very humble polite voice and in this video your voice was really soothing .. much respectful
If anyone wants to know anything
This guy would be one of the best
To get a understanding
Love all his shows
WATCH HIS SHOWS
Best video from young thinkers. This needs to be in every class room, everywhere, and, may be in boardrooms also.
Brian Cox! Awesome
This channel never disappoints! Even when topics I’m not necessarily interested in are discussed I enjoy the episode and I ALWAYS learn something!
Thanks for posting.
Brian Cox is awesome!! I just had to say that. ❤
Very thought provoking video. I've always found Brian Cox's viewpoints VERY Interesting. He sees the same things as other scientists, but he helps us think about it just a little differently than many, which can help us think differently ourselves. Fascinating!
no matter how we try and explain it, we still have to use language and abstract concepts that can be understood by the human mind so straight away there is probably a limit as to what we can comprehend with our human brains
What if concrete reality is just a metaphor that represents an abstract truth?
That’s assuming the information in our universe that led to our consciousness was put there by accident and random chance and not by a being with a mind and the intent for us to comprehend it with said consciousness. Just a thought. I’m not religious.
I love both these men. They are lucky to be passionate about their work and still interested by hard to resolve questions. The origin of life has always interested me but, at this time, we haven’t a single clue how it started. All we really know is that it’s eventually going to end. Such is the life of our sun.
Thank you Joe and Brian!
I adore Brian. No one else talks as both elequently and simply as he does. I can listen to that man talk for hours on end. I love that Brian brain.
Brian Cox did Wonders of Life, the greatest biological documentary of all time.
I really enjoyed that documentary!
Well done. I believe that physics, and science can explain the 'what' and the 'hows' of life, but not the 'who', or the 'whys'. Unlimited profundity.
Maths is applied logic. Physics is applied maths. Chemistry is applied physics and maths. Biology is applied physics, chemistry and maths. I love looking at biology questions from the chemistry and physics perspective. This discussion continues to fascinate me. I think of life as a very complicated series of chemical reactions. Each reaction tries to reverse entropy locally but has to increase the etropy of the universe. We play at reversing those reactions time and time again, but eventually they reach a conclusion and we die.
When it comes to the question of human meaning, Carl Sagan's explanation is as good as any, "We are a way for the Cosmos to know itself".
Precisely. Life is a by product of the universe . No different from stars, galaxies and rocks, however it gets interesting when we start talking about awareness and consciousness. Is the universe just having a human experience?
@@Lone_Star86 I don't think so. I think humans are having a cosmic experience. What about the possibility of other sentient life in the cosmos? Are we alone? Are we the first? Or are we just one of many sentient conscious beings in our Universe or a grander Multiverse? Who knows?
As intelligent as we think we are, we still only have some limited understanding of only 5% of observable matter. We don't know what dark matter or dark energy is, or if there are as yet more undiscovered forces of nature.
And what is reality? What is time? Are there other dimensions beyond our 3 physical dimensions and one temporal dimension of time? We don't know how our Universe came into being, or whether there was something before the 'Big Bang', or even whether this is a simulation, or a hologram.
We don't know how quantum really works, or what is truly fundamental. We don't know the origin of life, and we don't even know what is consciousness, only that we appear to be.
So we still have a long way to go on our journey of discovery. There are still many mysteries, but that's what makes life fun and interesting.
@@Lone_Star86 The Universe IS 'experience', in all possible forms..
spaceandmotion
Yet that’s not a satisfying explanation. It’s the equivalent of throwing your hands up and conceding “I don’t know”. The search continues..
@@SimonBrisbane Few people are ever satisfied with truth.. What if it turns out to be something very unsatisfactory? Will you just keep looking for something ‘else’ that does not exist?
Just by chance, I happened to watch this segment on Easter. I love the gift of science to give my mind something to do, something to wonder about. For me, the important lesson is to "keep seeking and you shall find". All roads eventually lead to the same Goal. Enjoy! And Happy Easter.
Really amazing, I enjoyed it so much
Informative, thanks.
That's why started studying biology for my Advanced level examinations.
please make more videos with brian cox. he is awesome
Amazing that these two guys can help me understand a sidgen of what they talked about. Not much compared to them mind you, but a million times more than my dumb a$$ knew before. Thank you guys.
And the guys cleared up my confusion about Entropy at a single stroke! 10.44 to 12.33. Thank you!
I always argued that if we can find the origin of life it should be through a combination of research on biology, physics, geology and behavioural science. This will remove inherent bias.
Good to see that we are slowly leaning in that direction
is the right direction
A fascinating question explored, and will continue to be for some considerable time. It is so great to see such excellent guests on such scientific programs as this being made. You struck gold to get Brian Cox, well done! Thank you, keep up the brilliant work team.
Be smart and stay curious 👍🚀🔬🔭🔎🧪
I don't know how to describe the profound impact THIS VIDEO had on me. It is hard to understate how well the content produced by "Be Smart" in a conversation with Brian Cox conveyed concisely the journey from the Big Bang to complex life via entropy. It was an epiphany for me. Now, I am so curious as to the nature of how protons fit into this equation (I realize that you indicated it is very complex). I also derived that entropy is a great mystery in may respects, yet it is one of the most important fundamentals of the universe. Thank you so much.
Please explain in simple terms how life came from non-living matter.
So fun, this episode. I love your work, Joe. And this is the episode of Be Smart that I've been waiting for! I'm a biologist with a fascination for cosmology, holograph theory, etc... I love the stuff from 11:18 to 13:02--the Pandora's box, the hologram if you will! In other words, the broader implications that entropy has through space/time on biological outcomes (that we see and feel and study and wonder about). More videos about biological information systems intersecting with the influence of cosmological forces please! 😃😋
Can you explain how proteins "automatically" select the correct chirality of amino acids in their synthesis? Out of the potential millions of choices? I assume as a biologist you have an inside track.

Amazing video. Loved every second of it. Keep up the good work.
this is one of the best episodes i've seen.
You and Brian Cox. Amazing ❤
Thank you so much for uploading this video. It is helping me get through the pandemic!
Love Brian Cox, thanks for this video ❤️
Thank you for the video. Loved the content argument.
I really miss the title "its okay to be smart" it was the perfect representation of joe and this channel in general 🥺
Do you know when they changed it or why? I haven't kept up with the channel recently and was a bit surprised at the name change.
@@patricial.3929 i honestly dont know why they changed it
@@patricial.3929 He said that channel's name... "it's okay to be smart" is really big, so he made it shorter...
@@NTdredd ah, I see. Though I liked their original name I can see why they'd choose to shorten it. Thank you!
@@patricial.3929 he also said that he didn't want to just say "it's okay to be smart." he wanted to challenge his audience to actually be smart.
Your content is always amazing, but this has to be one your best ever right here. I’d say it’s up there with Veritasium’s relativistic gravity one.
It's the happy gentle vibe for me
Great episode!
There is a definition of what life is. I don't believe there is a "meaning" to life. Life means only what each individual chooses to make it mean.
Does the word" life" evoke no associations in your associative apparatus, for what else is meaning?
Objective meaning: survival
Subjective meaning: whatever you want it to be!
Life...it sure beats the alternative.
The voices I can fall asleep to will forver be special for me
edit: souds like i have schizophrenia and maybe i do, but Brain is indeed a legend
At almost 74 years old my thoughts are moving towards the metaphysical side of life. A great video - thank you 😊
Really great conversation between two curious and informed people. Brian's calm, articulate responses, and his willingness to say "we don't know (yet)" really resonates with me. Contrast his demeanor with the arguably arrogant and er, 'self-centered?' demeanor of a deGrasse Tyson approach, and for me, it makes all the difference in my reception to what's being presented.
Yes I feel de Grasse is so smart he is stupid. Years ago I enjoyed him, but alas poor Yorick, I have cancelled him.
Exactly what is the "contrast" you speak of, since Neil deGrasse Tyson is also firmly in the "we don't know" camp?
please make more contexts with brian cox. he is awesome.

Our brains are dangerous to our selves because they carry memories, and you are talking about optical illusions to explain the miserable life?
