34:57 “[Alan] Turing’s brilliant mind saw that any calculation had two aspects: the data and the instructions for what to do with the data.” It’s actually fascinating that it took until the mid-1950s for someone to come up with that abstract idea since Joseph Marie Jacquard’s punch cards, demonstrated in 1801-so, exactly a century and a half earlier-worked on essentially the same principle.

Pity that its all Pseudoscience from the part where he starts to claim that information is part of Physics, like its a physical object itself. Because of this flaw of poor logic, this documentary is only useful from the start to about half way through. The rest is rubbish. Its more to do with mystical ancient religious beliefs than science.
@@mok822 and that is possibly the most stupid belief since the idea that the universe is a turtle sitting on the back of a larger turtle who sits on the back of an even larger one. Didn't you understand that the notion of "information" having anything to do with reality or physics is a steaming pile of shite? This idea of reifying information, is just another way for religious Mysticism to replace actual sane Physics.
Jim already has a slew of these, but I wish he developed videos detailing the history and depths of every corner of human knowledge. These should be required viewing for every person on the planet.
You know there are also universities all around the world right? The people that are interested in knowing, for the most part, are already searching this information out. Sure, some people don't have easy access, but there are also people that are unable to grapple with a lot of concepts. What are you going to do with them, in regards to your "requirement"? You found something interesting, now everyone else needs to find it interesting also? come on, be cool.

Mind-blowing! This is the most amazing series of bits I have ever encountered! Filled many of the holes in my brain and will inspire me going forward. God knows, there is beauty, structure and order to build! 🥰
The more and more I listen the more I feel that our presence here isn't by chance... I'm normally not one to express solid determination.. but I keep finding beautiful things that could've only been imagined. Everything in its presence is purely mysterious.
There is absolutely God. Tomato, tomato, let us glorify our creator for these beautiful and divine ironies, mysteries, synchronicities! Many throwing the baby out with the bath water.. at their expense.
Einstein once remarked, "...reduce concept to their simplest concepts, but no further.". There is benefit to practicing this idea, but I feel it only applies to the contemporary understanding of our surroundings or today's judgementally acceptable scientific or social laws
Professor Jim Al Khalili is amazing... his ability to explain things to a lay audience is legendary.............by far my favourite "Teacher" for all time ( and space) .
A true expert can explain any concept to a child. Those who say it is too complicated to explain, or the listener would not understand, do not fully know the subject.
Finally, a documentary that introduces one of the most understated influencers in our times, Claude Shannon, the father of information theory. We just don't hear much about this phenomenal under and unappreciated engineer. Thank you. Love his juggling machine too. Anyone interested in him should read "A Mind At Play" by Soni and Goodman.
God has everything to all. Yeah right. Give me a break. God can and cannot be easily explained. At the end.... But there are many ways of thing called by humans (animal man in hindi language hu= animal man = men) life, that talking about it will not make a push on individual.
It is the first time I heard of the demon's analogy in keeping record of 'states' of molecules. This shows how history is important in understanding the origin of 'concepts' developed by scientists!
Only because Humankind has been supressed and enslaved by RELIGION for last 6 000 years. The only analogy they knew was god and evil (both non-existent)
Doug, see my comment 6 levels above. The wonder universe we live in is designed. Oder doesn't come from total chaose, which is what the big bang suggest - at least when they leave out the presence of God, who brought all the matter into being before ordering it.
Are you sure your alive or is this just another simulation in someone else's computer? lol Or like Shrodinger's cat or how ever his names spelt are do you only exist because someone or something observed you? Sorry I'm just messing with you Doug.
And when you die, this beautiful elegant thought encoded in your brain, will be erased and released as energy to merely increase the total disorder in the universe.

When I saw "Punch Card", I know how the story will go to. Note: "Bug" in coding really comes from a bug blocked the reader of punch cards - how original computer works : )
In a recent double-blind study focused on a diverse and unsuspecting group of 500 random strangers, researchers found that the overwhelming majority of participants poled, “had a “good time”, and “would recommend to a friend,” , yet, polers were surprised to discover a not-insignificant number of outliers, indicating an excellent opportunity for honest self-reflection and a healthy realignment of personal/social perspective, values, and expectations.
It is the fifth time i watch this documentary. I really like it. The mere fact of stay under the rain... is like being constructed by large amounts of information encapsuled into water droplets.
All of this is, to a great extent, already contained in the theory of hylomorphism. Over 2,000 years ago, Aristotle said that all that there is in the universe is a compound of matter (hyle) and form (morphe). Matter is *informed* and that’s the only way it actually is real. Reality is hylomorphic. And as a bonus, another way to name form is by a Greek word that will be familiar to you: energeia.
The scientific method is the best thing that we as a specie came up with. Although we dont know a lot the little we know is what got us this far, not the religious nonesence most of us believe.
@@kamalzamani1130 wheres the proof? Jim never mentions it. Stop spreading gossip n rumor. No atheist would be so eloquent in speech. Richard Dawkins is an atheist. N u see how terrible he is with explaining things? Big difference.
He mentioned it publicly with Brian Cox during an interview. He made a figurative comparison atheism, and suggested that not collecting stamps is as much a "hobby" as not believing god is a "religion."

As a control we will force the snail to watch. If the snail smells the vibrations of this spooky action at a distance then we can all rest assured the moon landings were faked.
I've not read all of the comments of course. But, when thinking of Maxwell's demon, there is an obvious expenditure of energy to me. He opens a portal to allow the atom to cross. He has to expend some energy in some sort of way to open and close the portal. Probably much more than the atom uses to glide through the opening. I know it's just a thought experiment. But the conversations about such things is what makes it so great.
I don't think it's so much the physical actions. More that you can "process" order in the universe at no cost. Basically he was imagining a computer, and saying they don't cost anything to computate. The door and dividing molecules, could be any task it's doing, doesn't even have to be physical
A byte is essentially a punch card with 8 bits. Most modern instruction sets use 64 or 128 bits. Every instruction is a virtual punch card, and like this documentary states, have enough punch cards and you can represent anything.
in this paper Shannon did something absolutely incredible he took the vague and mysterious 44:17 concepts of information and managed to pin it down now he didn't do this using 44:23 some cleverly worded philosophical definition he actually found a way to measure the information contained in a 44:30 message amazingly Shannon realized that 44:37 the quantity of information in a message had nothing to do with its meaning instead he showed it was related solely 44:45 to how unusual the message was 44:51 information is related to unexpectedness so news is news because it's unexpected
Talking about the energy required to delete one bit? What about the energy the demon uses to follow the particles? What about the energy needed to open a close the separator?
Yes! Yes it is! That is your fourth dimension. It is not time. Time is not a dimension, but indeed information is a good way to approach that 4D concept.
Conflating the thing with what may be said about the thing. "In the beginning was the Word...." How a thing is described causes the thing itself. A very old idea, indeed. Magic.
@@kirbymanlegro8201 I think it must be that 'order' is the ratio between energy and matter. Because matter is the concentration of energy; order would be more matter relative to energy in a given system. When something comes into existence by subtracting energy from its surroundings, it increases order. Disorder would be the more even distribution of energy: IOW entropy. As things decay, they turn into energy; until there is nothing left but smoothly distributed energy...
@Pouty MacPotatohead Define 'order'. I did. When everything is reduced to energy; there is maximum disorder. How does that apply to the idea that a thing is created by the description of the thing?
@@michaelpcoffee Order is a system that requires less information to completely describe. Disorder is a system that requires a large amount of information to describe.
Right, the amount of information needed to describe the universe is so great that a human mind cannot cannot imagine it. For instance: there are more atoms in approx. 3 grains of sand than all the grains of sand on earth. And we now know that atoms are made up of even smaller particles to an exponential level. To describe the amount of information needed to describe the universe is titanic but that word doesn't do it justice.This video is one of the best I've ever seen. It explains the history of something which is paramount in human existence. One thing I disagree with is at 52:21 when he say the demon sitting on top of the two connected boxes letting the fast atoms move to one side and the slow ones to the other side. He says that the demon can create order without expending any energy. If the demon has to open and close a slight opening between the two boxes to make this happen that takes energy.
then having defined this basic unit he even gave us a name for it one we're all 46:40 familiar with today he used a shortening of the phrase binary digit bit the humble bit turned 46:50 out to be an enormous leap our falaya [Music] 46:55 the bit is the smallest quantity of information it is highly significant 47:01 because it's the fundamental item it is the smallest unit of information in which there is sufficient discrimination 47:07 to communicate anything at all 47:14 the power of the bit lay in its universality 47:19 any system that has two states like a coin with heads or tails can carry one 47:26 bit of information 1 or 0 punched or not 47:33 punched on or off stopped or go all of 47:38 these systems can store one bit of information
That was excellent. I did a Computer Science degree in the 1990s and have written software for the decades since but this was has got me thinking about different ways of how information can be represented and the rather crude approximation with which we use computers right now to simulate and abstract from reality.
1:14 "Scientists have discovered that information is a fundamental part of our Universe". Information alone is meaningless without consciousness. If information is a fundamental part of the Universe, then consciousness must also be a fundamental part of the Universe.
Consciousness, along with the other characteristics of intelligence, is an amazing feature in animals - especially in large-brain mammals such as ourselves. But the DNA of a tree seed informs its development and survival as a tree, without any consciousness. Yes, the tree has no opinion about the value of its existence - no concept of meaning; but I still see it as significant.
@@RichardWilkin "But the DNA of a tree seed informs its development and survival as a tree, without any consciousness. Yes, the tree has no opinion about the value of its existence - no concept of meaning; but I still see it as significant." What is the relationship between DNA and consciousness? There is no way of knowing whether a tree is conscious or unconscious or what it is like to be a tree (or a bat or whatever). By the same token, there is no way of knowing whether a human being is conscious or unconscious. External behaviour and neural networks activity in the brain are material correlates that provide no direct evidence of consciousness. The only direct evidence of consciousness is the felt presence of subjective experience that is solipsistic by definition. Anyone can indeed doubt that any other being is conscious and no one can prove to another that they have a conscious subjective experience.
Interesting that some people think that trees might have consciousness. I'm pretty sure that it's a function of the brain, and that trees don't have brains. However, people seem to believe what they want to.

30:20 - John Vincent Atanasoff, OCM, (October 4, 1903 - June 15, 1995) was an American physicist and inventor, best known for being credited with inventing the first electronic digital computer. Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer.
Actually, I think Charles Babbage deserves priority for conceiving and reducing to practice the use of binary coded instructions (programmable on cards in his prototype) for performing arithmetic. His planned improvements represented (anticipated) the "Turing complete" concept which includes conditional instruction flows.
Maxwell's demon links together two of the most important concepts in science 55:13 the study of energy and the study of information and shows that the two are 55:18 profoundly linked what we now know is that information far from being some abstract concept 55:25 obeys the same laws of physics as everything else in the universe 55:33 [Music] information is not just an abstraction 55:41 just a mathematical thing or formula that you write on the paper actually information is carried by something so 55:48 it's encoded onto something a stone a book a CD whatever there's a carrier 55:55 where the informations on and that means that information behaves according to 56:01 those laws of physics so it can all break the laws of physics what humanity 56:11 has learnt over the last few millennia is that information can never be 56:16 divorced from the physical world [Music] 56:23 but this is not a hindrance what makes information so powerful is 56:29 the fact it can be stored in any physical system we choose from using 56:36 stone and clay to allow information to be preserved over eons - using 56:42 electricity and light so it can be sent quickly the medium that stores 56:47 information gives it unique properties 56:54 today scientists are exploring new ways of manipulating information using 57:00 everything from DNA to quantum particles they hope that this work will usher in a 57:06 new information age every bit as transformative as the last 57:13 what we now know is that we're just at the beginning of our journey to unlock 57:19 the power of information 57:29 [Music] 57:37 it's always been clear that creating physical order the structures we see around us has a cost we need to do work 57:45 to expend energy to build them but in the last few years we've learned that ordering information creating the 57:53 invisible digital structures of the modern world also has an inescapable cost as abstract and ethereal as 58:01 information seems we now know it must always be embodied in a physical system 58:06 I find this an incredibly exciting idea think about it this way a lump of clay 58:12 can be used to write a poem on molecules of air can carry the sound of a symphony 58:18 and a single photon is like a paintbrush every aspect of the physical universe 58:25 can be thought of as a blank canvas which we can use to build beauty 58:31 structure and order [Music]

You know there are also universities all around the world right? The people that are interested in knowing, for the most part, are already searching this information out.

Love how well Jim simplifies complex topics -- an impressive educator.
Yeah
If you cannot repay the information to a layman do you really understand the topic?
Einstein once remarked, "...reduce concept to their simplest concepts, but no further.". There is benefit to practicing this idea, but I feel it only applies to the contemporary understanding of our surroundings or today's judgementally acceptable scientific or social laws
al-Khalili sets me of into every direction ...
Professor Jim Al Khalili is amazing... his ability to explain things to a lay audience is legendary.............by far my favourite "Teacher" for all time ( and space) .
A true expert can explain any concept to a child. Those who say it is too complicated to explain, or the listener would not understand, do not fully know the subject.
Very true!
His selection of images is informative and dovetails with the elementary dialogue.
Finally, a documentary that introduces one of the most understated influencers in our times, Claude Shannon, the father of information theory. We just don't hear much about this phenomenal under and unappreciated engineer. Thank you. Love his juggling machine too. Anyone interested in him should read "A Mind At Play" by Soni and Goodman.
Absolutely! Shannon was every bit as important as Turing, Zuse and other innovators and deserves to be as equally well-known.
Unfortunately Khalil neither understands Shanon nor Thermodynamics. It's a shame.
@GRAPHENE IS IN THE MASKS, SWABS and PCR TESTS!!! YOU are a hoax.
God has everything to all. Yeah right. Give me a break. God can and cannot be easily explained. At the end.... But there are many ways of thing called by humans (animal man in hindi language hu= animal man = men) life, that talking about it will not make a push on individual.

Hi William… are in the UK? and do you still pay TV licence?
All of this is, to a great extent, already contained in the theory of hylomorphism. Over 2,000 years ago, Aristotle said that all that there is in the universe is a compound of matter (hyle) and form (morphe). Matter is *informed* and that’s the only way it actually is real. Reality is hylomorphic. And as a bonus, another way to name form is by a Greek word that will be familiar to you: energeia.
The scientific method is the best thing that we as a specie came up with. Although we dont know a lot the little we know is what got us this far, not the religious nonesence most of us believe.

@@thecrichters8680 THE CLEAR AND UNIVERSAL MATHEMATICAL PROOF THAT E=MC2 IS F=MA:
Gravity IS ELECTROMAGNETISM/energy, AS E=MC2 IS F=MA. The Earth (A PLANET) is a MIDDLE DISTANCE form that is in BALANCED relation to the Sun AND the speed of light (c), AS the stars AND PLANETS are POINTS in the night sky; AS E=mc2 IS F=ma. ACCORDINGLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. SO, the Earth constitutes the FULL DISTANCE in/of SPACE in BALANCED and UNIVERSAL relation to what is the MIDDLE DISTANCE in/of SPACE; AS E=MC2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, time DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA !!! GREAT !!! BALANCE and completeness go hand in hand. Indeed, it ALL CLEARLY makes perfect sense.
Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA. (The stars AND PLANETS are POINTS in the night sky.) "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Accordingly, the rotation of the Moon MATCHES it's revolution. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!
By Frank DiMeglio
WHY ELECTROMAGNETISM/ENERGY IS UNIFIED AND BALANCED WITH/AS WHAT IS GRAVITY:
Gravity AND ELECTROMAGNETISM/ENERGY are LINKED AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, Einstein's equations and Maxwell's equations are unified (given the addition of a fourth spatial dimension); AS E=mc2 is DIRECTLY and fundamentally derived from F=ma; AS TIME DILATION proves that electromagnetism/ENERGY IS GRAVITY. ACCORDINGLY, Einstein's equations predict that SPACE is expanding OR contracting in and with TIME; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.)
Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of the Moon MATCHES it's revolution. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/ENERGY IS GRAVITY.
Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. THE SUN purely exemplifies time DILATION. INSTANTANEITY is FUNDAMENTAL. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!!
The stars AND PLANETS are POINTS in the night sky. Let's compare this directly with BOTH a falling object AND the speed of light (c). Great. E=mc2 IS F=ma. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. INSTANTANEITY is FUNDAMENTAL to the FULL and proper understanding of physics/physical experience. Ultimately and truly, TIME is possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The ultimate unification of physics/physical experience combines, BALANCES, AND includes opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT. It ALL makes perfect sense. THINK !!!
The Earth that undergoes time DILATION IS thus represented (ON BALANCE) as what is A POINT in the night sky, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (So, notice that the BLUE SKY IS no longer visible. Think.) E=mc2 IS F=ma. It is FULLY proven. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Alas, the INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. I have truly, CLEARLY, AND MATHEMATICALLY unified physics/physical experience. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. (Notice the black space of THE EYE, AND the DOME of a person's eye is ALSO visible.) THE EARTH is ALSO blue. Again, E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. Time dilation proves that E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS electromagnetism/ENERGY IS GRAVITY. It ALL makes perfect sense. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE AND completeness go hand in hand.

this dude has been in my best people for awhile now next step is to meet the dude and figure out quantum evolution thing by actually mating the robin with the tadpole during the tadpoles metamorphasis. As a control we will force the snail to watch. If the snail smells the vibrations of this spooky action at a distance then we can all rest assured the moon landings were faked.
I've not read all of the comments of course. But, when thinking of Maxwell's demon, there is an obvious expenditure of energy to me. He opens a portal to allow the atom to cross. He has to expend some energy in some sort of way to open and close the portal. Probably much more than the atom uses to glide through the opening. I know it's just a thought experiment. But the conversations about such things is what makes it so great.
I don't think it's so much the physical actions. More that you can "process" order in the universe at no cost.
Basically he was imagining a computer, and saying they don't cost anything to computate.
The door and dividing molecules, could be any task it's doing, doesn't even have to be physical
But the job of "sorting" what's a fast molecule or slow molecule.
Seemed to come at no cost, not the actual physical "sorting"
We know the energy cost of opening a door, but how does the door know to open, and where is the energy of that information.
A byte is essentially a punch card with 8 bits. Most modern instruction sets use 64 or 128 bits. Every instruction is a virtual punch card, and like this documentary states, have enough punch cards and you can represent anything.
... an absolutely interesting and amazing documentary ...

How a thing is described causes the thing itself.
A very old idea, indeed.
Magic.
What is order and disorder? Csn you help me,?
@@kirbymanlegro8201 I think it must be that 'order' is the ratio between energy and matter. Because matter is the concentration of energy; order would be more matter relative to energy in a given system. When something comes into existence by subtracting energy from its surroundings, it increases order. Disorder would be the more even distribution of energy: IOW entropy. As things decay, they turn into energy; until there is nothing left but smoothly distributed energy...
@Pouty MacPotatohead Define 'order'. I did. When everything is reduced to energy; there is maximum disorder.
How does that apply to the idea that a thing is created by the description of the thing?
@@michaelpcoffee Order is a system that requires less information to completely describe. Disorder is a system that requires a large amount of information to describe.
@@user-hh2is9kg9j
That requires a describer.
I like Jim,love his documentaries
Science behind Tenet. "Reverse entropy"
Right, the amount of information needed to describe the universe is so great that a human mind cannot cannot imagine it. For instance: there are more atoms in approx. 3 grains of sand than all the grains of sand on earth. And we now know that atoms are made up of even smaller particles to an exponential level. To describe the amount of information needed to describe the universe is titanic but that word doesn't do it justice.This video is one of the best I've ever seen. It explains the history of something which is paramount in human existence.
One thing I disagree with is at 52:21 when he say the demon sitting on top of the two connected boxes letting the fast atoms move to one side and the slow ones to the other side. He says that the demon can create order without expending any energy. If the demon has to open and close a slight opening between the two boxes to make this happen that takes energy.
Brilliant video! I use Firefox and uBlock so I was confused to see people complaining about ads.

46:50
out to be an enormous leap our falaya [Music]
46:55
the bit is the smallest quantity of information it is highly significant
47:01
because it's the fundamental item it is the smallest unit of information in which there is sufficient discrimination
47:07
to communicate anything at all
47:14
the power of the bit lay in its universality
47:19
any system that has two states like a coin with heads or tails can carry one
47:26
bit of information 1 or 0 punched or not
47:33
punched on or off stopped or go all of
47:38
these systems can store one bit of information
That was excellent. I did a Computer Science degree in the 1990s and have written software for the decades since but this was has got me thinking about different ways of how information can be represented and the rather crude approximation with which we use computers right now to simulate and abstract from reality.
Al-Khalili is a treasure! I have enjoyed many of his presentations. Thank you for this video. 👍🏻👍🏻👍🏻
FYI Jim doesn't read the comments, neither does Spark.
1:14 "Scientists have discovered that information is a fundamental part of our Universe".
Information alone is meaningless without consciousness. If information is a fundamental part of the Universe, then consciousness must also be a fundamental part of the Universe.
Consciousness, along with the other characteristics of intelligence, is an amazing feature in animals - especially in large-brain mammals such as ourselves. But the DNA of a tree seed informs its development and survival as a tree, without any consciousness. Yes, the tree has no opinion about the value of its existence - no concept of meaning; but I still see it as significant.
@@RichardWilkin "But the DNA of a tree seed informs its development and survival as a tree, without any consciousness. Yes, the tree has no opinion about the value of its existence - no concept of meaning; but I still see it as significant."
What is the relationship between DNA and consciousness?
There is no way of knowing whether a tree is conscious or unconscious or what it is like to be a tree (or a bat or whatever).
By the same token, there is no way of knowing whether a human being is conscious or unconscious. External behaviour and neural networks activity in the brain are material correlates that provide no direct evidence of consciousness. The only direct evidence of consciousness is the felt presence of subjective experience that is solipsistic by definition.
Anyone can indeed doubt that any other being is conscious and no one can prove to another that they have a conscious subjective experience.
Interesting that some people think that trees might have consciousness. I'm pretty sure that it's a function of the brain, and that trees don't have brains. However, people seem to believe what they want to.

I suggest alxo to read Mr Tompkins Adventures by G. Gamow. An interesting passage is where Maxwell's Daemon play tennis with the molecules...
30:20 - John Vincent Atanasoff, OCM, (October 4, 1903 - June 15, 1995) was an American physicist and inventor, best known for being credited with inventing the first electronic digital computer. Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer.
Actually, I think Charles Babbage deserves priority for conceiving and reducing to practice the use of binary coded instructions (programmable on cards in his prototype) for performing arithmetic. His planned improvements represented (anticipated) the "Turing complete" concept which includes conditional instruction flows.
Was the difference engine binary coded?
I was very surprised his name didn't come up!
I am from university of surrey and a fan of Professor Jim. 👍
Maxwell's demon links together two of the most important concepts in science
55:13
the study of energy and the study of information and shows that the two are
55:18
profoundly linked what we now know is that information far from being some abstract concept
55:25
obeys the same laws of physics as everything else in the universe
55:33
[Music] information is not just an abstraction
55:41
just a mathematical thing or formula that you write on the paper actually information is carried by something so
55:48
it's encoded onto something a stone a book a CD whatever there's a carrier
55:55
where the informations on and that means that information behaves according to
56:01
those laws of physics so it can all break the laws of physics what humanity
56:11
has learnt over the last few millennia is that information can never be
56:16
divorced from the physical world [Music]
56:23
but this is not a hindrance what makes information so powerful is
56:29
the fact it can be stored in any physical system we choose from using
56:36
stone and clay to allow information to be preserved over eons - using
56:42
electricity and light so it can be sent quickly the medium that stores
56:47
information gives it unique properties
56:54
today scientists are exploring new ways of manipulating information using
57:00
everything from DNA to quantum particles they hope that this work will usher in a
57:06
new information age every bit as transformative as the last
57:13
what we now know is that we're just at the beginning of our journey to unlock
57:19
the power of information
57:29
[Music]
57:37
it's always been clear that creating physical order the structures we see around us has a cost we need to do work
57:45
to expend energy to build them but in the last few years we've learned that ordering information creating the
57:53
invisible digital structures of the modern world also has an inescapable cost as abstract and ethereal as
58:01
information seems we now know it must always be embodied in a physical system
58:06
I find this an incredibly exciting idea think about it this way a lump of clay
58:12
can be used to write a poem on molecules of air can carry the sound of a symphony
58:18
and a single photon is like a paintbrush every aspect of the physical universe
58:25
can be thought of as a blank canvas which we can use to build beauty
58:31
structure and order [Music]
wtf is this
