- The great 19th-century Austrian physicist, Ludwig Boltzmann was one of the most important proponents of the idea that all matter is made of atoms.
Today no one doubts this is true but in Boltzmann's day it was a controversial idea and many of his contemporaries disagreed with him. But Boltzmann used brilliant mathematical arguments to show that many aspects of the world we observe, like the behaviour of heat, can be explained if one accepts that atoms are real.

Hi Spark!
I always liked documentaries with Jim Al-Khalili!
But...
I have a question for you!
What do you think about that book which claims to have figured out what are and how work black holes. According to it those might be very brightly shining objects that become invisible exactly because of the laws of physics.
Also, this book suggests a new idea for the origins of the Universe. According to it, it is eternal and uncreated and that is the only way it could be. The book describes the philosophy behind that. It it logical though.
Also, the book describes tides in a completely different way. Yes, it still is because of the Moon, but in completely different way from what we think today.
Among other things the book looks at failures of flat eart theory and hollow earth theory. It even addresses the question what is truth...
Anyway, what do you think about those theories?
The book is titled as "NEW THEORY OF WHERE THE UNIVERSE COMES FROM AND HOW IT WORKS".
Also, the book claims to have figured out the true pattern of Magnetic field and how it works...
Also, the questions about free will and Astrology are discussed in this book explaining why the latter should be taken as seriously as weather forecast and the free will is possible only within certain conditions. The most important of which is - we have to understand the reality around us...
Its author uses a funny pen name - george warehouseman... Possibly to trigger some unstable PhD's... ha ha ha
Also, the book addresses questions about what is good and bad, what is Truth and many, many others.
@@ChrisMattar ppppp
@vladimir putin is andrei panin jfk is jimmy carter nice dude. Love that you don't just accept facts and are trying to disprove what everyone's " normal" point of view.
But one important feature of science is to question yourself as well.
In flat earth -
Where is the center of gravity?
What is at the edge of flat earth?
If you question yourself and others you'll get closer to the truth
Thank you, Professor al-Khalili, for years of wonderful physics programs. I have watched/listened to many of them more than once. You're a treasure.
This professor makes great videos. He explains things clearly and is easy to follow without coming off as condescending.
True!
I agree. Love this guy. I've seen several of his vids.
hehe
Anthony Andrea
Be well
@MeMyself AndEye Are you some kind of conspiracy theorist, flat Earther nut? What exactly does he say that's untruthful?
Jim is easily a top science educator if not the very best. His demeanor, his enthusiasm, his knowledge, his voice...and so much more!
This Jim and BBC combo is just AWESOME. I wish these dudes would've kept on making docs. Simple, enlightening, captivating, life changing.
Jim Al-Khalili is the righteous heir to the great Carl Sagan. Thank you!
The one about information changed me
why always the need to compare things... now you insulted both of them
@@seekter-kafa You don't feel the need to compare things, others do. I don't eat pork, others do. It's called the world, dude, and it's filled with possibilities.
A simple comment, done with good intentions, does not reduce anyones greatness.
No one was offended. Sagan is dead and Jim is not reading this comment section.
I just mentioned two people that summon in me great admiration and gratitude.
All is cool dude, just relax, go for a swim in the sea, or climb a mountain, and the unbearable pain of external comparisons will be gone...
@@bartolomeugusmao4445 no wonder this world is going to shit
@@seekter-kafa Man, your world is going to shits, not mine. I'm cool.
Is your world going to shits because people keep comparing cientists?
Prof. Jim Al Khalili's films are the finest science documentaries ever made- anywhere. The collection of his docs are a MUST SEE for anyone who has an interest in the history and mechanics of our world and the universe we all inhabit.
British really can make very good documentary .
the way they speak very softly without yelling and gesticulating.
In difference with us documentaries you have the presenter speaking loudly like it is a war documentary
rightly said.
FYI, If it wasn't for the USA we would be speaking German.

FINALLY! A clear and concise explanation of entropy! A concept I've been struggling to understand for quite some time. And it doesn't surprise me at all that the man who came up with the idea of entropy was suffering from severe depression. Actually, it explains exactly how he got to see it....
it paints a bleak picture, doesn't it? I encountered it during my chemistry studies - along with the physics (such as thermodynamics, and esp entropy as explained in this video), the biochemistry, which showed to me that we are nothing but chemicals reacting according to laws of physics, is difficult to deal with at first. The understanding that all that I (or you, or anyone) think, feel, do, want, hate, love, all of it is simply a chain of chemical reactions performed by complex structures composed of only a handful of different elementary particles, can be very depressing. Not even in a sad way, but more in an apathetic way. I kind of learned to ignore that aspect of reality over the years, but I would be lying if I said that it didn't affect the way I view life.
@@SMPKarma encountered this in biochem while trying to be a medical job. It gives you a weird lens on even though it’s all chemical reactions, the energy of people is real and therefore everything derives meaning from that, what we give the energy to all that. Entropy and the connections you can draw out of it to apply to life is interesting
I’m not sure sure it’s what happened with it lol lol 😆 I’m oooooooooo
Here's how my dad described entropy to me. A whirlpool high in the mountain stream fills up with rocks. The snow melts, the water rushes down causing the whirlpool to swirl. Grinding all the rock to fine sand. This sand is concentrated in a sandbar year after year and eventually lower levels are compact ed. Dirt clods out of that level are eventually ground into fine dust by heat, cold and rainwater. When this dust is dry it flies up in the upper atmosphere, where each Mote of dust has water crystalized around it forming ice which then falls back to earth and becomes rain.
@@SMPKarma To be a top down and truly great physicist, you need to be a top down and truly great mathematician. Here's the CLEAR proof ON BALANCE.
ULTIMATE, CLEAR, BALANCED, INTEGRATED, IRREFUTABLE, AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/energy is gravity:
Consider what is TIME. E=MC2 is taken directly from F=ma, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS the rotation of WHAT IS THE MOON matches it's revolution; AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); AS the stars AND PLANETS are POINTS in the night sky ON BALANCE; AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Great. Consider WHAT IS THE EYE ON BALANCE !!! Great. c squared CLEARLY represents a dimension of SPACE ON BALANCE. GREAT. Consider TIME AND time dilation ON BALANCE. Consider what is THE SUN ON BALANCE. GREAT. Indeed, notice what is the orange AND setting Sun ON BALANCE !! ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Consider WHAT IS THE EYE ON BALANCE !!!! GREAT ❤️❤️❤️❤️. Finally, what is lava IS orange; AND it is even blood red. Excellent.
By Frank DiMeglio
Consider what is the man (AND THE EYE ON BALANCE) who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Indeed, in identifying or considering what is THE EYE/EARTH balance, what is THE EARTH is ALSO BLUE. Great. NOTICE: Gravity cannot be shielded (or blocked) ON BALANCE. Magnificent !! Water flows downhill. Great.

I absolutely love Professor Jims videos, at 6o years old being able to watch and enjoy knowledge brought to one in lay mans terms not a period of attempting to memorise facts and figures, or to dive deeper into what really interests one almost makes me want to go back to school. Well done, bravo and thankyou.
These documentaries by Jim Al-Khalili are like comfort food for a hungry scientific mind. ;)
@@BillAnt: Yes! I hadn't thought of it that way. But these videos are like really, really good chocolate cake for my hungry, (non) scientific mind. I just wanna know how stuff works! And he's amazing!
Reply to Ed. Many questions.

It's intriguing to think how Boltzmann's bouts of depression and ultimate self-destruction were a manifestation of his profound ideas.
I’ve thought the same thing. A lesson for everybody who has big ideas. Don’t give up no matter how dark it gets. don’t listen to the haters
The proverbial thin line between genius and insanity is manifested here.
Makes me so sad that with such a great mind, depression could stand in his way and ultimately make him doubt and fall into his own darkness. He missed out being lifted into the light by a few years..... so sad, he would never know, but leave with doubt.
Entropy in a man --- the self destruction of Bolzmann, the entropy if you will.
That's fucked
One of the most fascinating videos I ever watched in recent times on youtube. Understanding the thermodynamic properties without any board and chalk/ marker
Thank you for talking about Gottfried Leibniz
for a change.
Everyone talks non-stop about Newton - great guy - we all know that.
But Gottfried Leibniz
seems to be an afterthought all the time. He's mentioned as that guy that co-invented Calculus but never anything about the man and his thought process and what he contributed.
Bravo!!!
Your shows are great Jim I've watch them twice you make them really interesting and exciting to watch thanks man
Pete Mchardy... you don't believe in punctuation obviously.
One of the best documentaries ever produced. I watched it over and over again.
I really like how you lead up to every point with an overly dramatic monologue and then repeat the 'suspenseful' closing statement two or three times. Also those 45 second establishing shots of the horizon or random guy playing the piano really set the scene nicely before actually getting to the point. Perfect blend of interesting and tedious content, thanks!
Wow - if only we could have seen this while studying science [biology, chemistry and more to the point - physics] in school, back in the day. Very interesting and fascinating - thank you very much.
Yes, I totally agree with Dedrick Howell, what I would love to do is throttle those that bring the whole thing together and bang in the overpowering back ground noise that can drown out what Prof. Jim Al-Khalili is saying. If you must have it, then tone it down by at least half.
Proffesor Jim Al-Khalili’s use of language as masterful, at least in my brain he has had a profound effect into the understanding of Entropy in the right historical context , Thank you !
The formulation of the concept of entry and the way that was presented gave me goosebumps.
unfortunately when we were students we did not had such rich presentations to explain complex concepts.
There is a reason for that. Complex concepts require more than just flashy pictures. ;-)
You can say that again. All this knowledge at your fingertips. Only a click away. Rate of discoveries will skyrocket! And some will be by AI-enabled computers.
“Have”. Happily, we DID have rich presentations which explained complex concepts. But then, sadly, the fuzzy-thinking leftist fruitcakes took over most of America’s academies.
@@andiofski2653 Dude, the rate at which you can assimilate information is not limited by any external factors, right now. My university had over one million books in the science library. Just how many of those can you read in your lifetime, let alone understand? ;-)
@@wiltonsmith3397 Look, Ma! There is the kid that didn't go to university. ;-)
Prof Al-Khalili is the best, theres a lot of great scientific documentaries made, but no one presents them like he does. You can feel his own love of science come through in each programme.
I have traveled the world and back again; served in 3 wars, attended multiple military schools, colleges, and other types of educational venues. But...this gentleman and scholar, always seems to amaze me and bring things to light in which I either forgot, or slept through...lol. Love his teachings.
The Bankers and MIC thank you for your contribution to their massive wealth
What a great story you've told beautifully, infecting us with the enthusiasm you feel for these people and their genius and insights.💐
This guy's documentaries are top tier. Priceless
These videos are awesome! Keep them coming!
Al Khalili never fails to disappoint. I love the mix of the historical with the hard science, it's so much more captivating than black and white equations. Science is and always has been about PEOPLE.
Storytelling is an ancient art that desperately needs re-integration into academia, and prof Jim is one of the best propronents of this style in my opinion.
gee mr murgatroyd, i never would have guessed without your help.
I love Professor Al-Khalili, he always talks about so many interesting topics, I end up reflecting on things every time I watch his documentaries, thank you!
Fantastic Documentary! I love the cinematography, time lapse, infrared photography as well as accredited contributors to science. Supurbly done! So glad I took the time to watch this!!!
Giggety giggety giggety
Love it, very helpful, thanks to everyone for made this happen 🇲🇽🇺🇸
This is a great documentary. learnt more than I did before clicked it watch
Who is the film and production crew behind these documentaries? They’re really really good!
It was originally on the BBC irrc
Jim al-Khalili made some brilliant docs for the BBC. Those written and directed by Nick Stacey are the best. Viz.
Everything and Nothing, Order and Disorder.
Absolutely captivating in every respect
I must have viewed his series well over a hundred times down through the years. (Additionaly, the music is SENSATIONAL!)
Many thanks to you, Prof. Al Khalili !
This is a seriously great documentation...
I just got the custom license plate "ENTROPY".... further the tagline on the state license is "powering the future". Awesome!
The coordination and presentation of the video is on another level👏
I really admire the narrative and presentation style here,
it makes you think,
you are not just spoon fed information.
One of the best production of this decade, this deserve way more views!!"
Professor Al-Khalili’s walkoff after each explanation is iconic. Lol.
I know right! He says two sentences and then walks off
Yes. I noticed that :)
lol thats like a mic drop
I can't un-see it, now!
@@sosyl BALANCED attraction and repulsion is fundamental regarding what is physics/physical experience, or there wouldn't be SPACE OR TIME. BALANCE AND completeness go hand in hand. What makes gravity, ON BALANCE, a constant force is that it cannot be shielded (or blocked). Gravity is ELECTROMAGNETISM/energy (in and WITH TIME) consistent WITH what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE. SO, a photon IS at the center of WHAT IS the Sun; as this would then CLEARLY be consistent with the requirement of time AND SPACE. (Consider what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE.) Carefully consider what is THE EARTH/ground ON BALANCE. Consider what is a TWO dimensional surface OR SPACE ON BALANCE !! Consider what is perpetual motion, AND consider TIME (AND time dilation) ON BALANCE. Consider what is THE EYE ON BALANCE. Notice what is the associated black “space” AND the dome AS WELL. NOW, carefully consider WHAT IS THE SUN (ON BALANCE); as TIME is NECESSARILY (AND CLEARLY) possible/potential AND actual (ON/IN BALANCE). CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites ON BALANCE; as the stars AND PLANETS are POINTS in the night sky (ON BALANCE). Consider TIME (AND time dilation) ON BALANCE. E=mc2 is taken directly from F=ma. Indeed, the ultimate mathematical unification (AND UNDERSTANDING) of physics/physical experience combines, BALANCES, AND INCLUDES opposites; as ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); as this CLEARLY explains F=ma AND E=mc2. AGAIN, consider what is TIME (AND time dilation) ON BALANCE !! Again, carefully consider WHAT IS THE MAN who IS standing on WHAT IS THE EARTH/ground ON BALANCE !! BALANCED inertia/INERTIAL RESISTANCE is fundamental (ON BALANCE).

Jim is one of my favorite science communicators.
Your videos are excellent Jim thank you
Dude, this documentary or shall I say Oscar deserving art, is no less than a masterpiece. Prof. Khalili to me is equivalant or greater than Carl Sagan in terms of being a scientific inspiration to a whole planet. Beautiful.
You started your sentence with the word "dude". ('.')
Khalili deserves more recognition than Neil deGrasse Tyson
good work bro, keep up this amazing content for many years to come!
Wonderful documentary done on the subject matter by Professor Jim.
Excellent. I really enjoyed it. Thank you.
Great video but for us hard of hearing the loud droning music makes some of the dialogue incomprehensible
FYI

I find the transcript useful for times such as this. This can be accessed via the horizontal ellipsis (the three dots) menu at the bottom right of the screen.
I thought because this stuff was pirated. But looked at their channel and they claim to have licenses for all this stuff. So kind of odd they have tampered with the audio.
Me thinks they lie, and that they be pirates arrr ye matey!
LOL!
I watched Everything and Nothing, IMHO it's the perfect "sequel" to Carl Sagan's: "Cosmos". I really liked it and I think I AM going to love this one too.
I like it when information captures my full attention. Entropy is not as infallibly depressive as one might think, because "the world is falling apart in a seriously interesting way."
Just amazing, keep these documentaries coming please.
Another great documentary and great to learn about all these amazing scientists they don't mention in school; thank you Dr Al-Khalili!
Only constructive comment - it would have been nice to follow the discovery of atoms with how they release energy (no mention of e=mc^2); it just jumped all the way to hydrogen fusion (which is of course incredibly interesting and promising)
The only “scientist” I remember being mentioned in school…. Was Thomas Edison…. And I have a hard time counting him as a scientist…
Unless you want to count “marketing” and “the study of patent law” as sciences.
While thermal energy tends to spread out by entropy, matter in the universe tends to clump together due to gravity which again creates heat. It's strange how the two forms of energy work against each other.
After all, us humans fall apart at the end of our lives, a true manifestation of our final entropy.
These documentaries by Jim Al-Khalili are like comfort food for a hungry scientific mind. ;)
Yes, but matter is also spreading out. The Universe is expanding at great relative speed.
I would argue that matter clumping together is a local phenomenon.
You thoughts?
@@pas9ify - Indeed clumping of matter by gravity and electrostatic charge is a relatively local phenomenon. Looking at the big picture of the Universe, ultimately it will end up in total entropy (the Big Chill) due to matter always seeking out the lowest state of energy and randomness.
@@BillAnt Thanks Bill!
Thanks for the very well done film. .Really liked the music and visuals. I especially liked FLIR images of the equation for heat written with a hair drier. Man the English are the best at science. Certainly a cut above. Good job old chap!
WOW! THIS IS A MASTERFUL PIECE OF ART!!! THANKYOU FOR SHARING!!!!!
Thank you for an intriguing presentation of energy and it's fall to entropy. I wouldn't hold my breath for fusion power however. That golden ring has been hanging out there twenty years in the future for like forever. Well done.
Especially since we've got already fission so well refined... and Gen-IV reactors are right around the corner, its going to be a renissance for reactor technology
even fusion does not prevent a fall to entropy, it just takes if form a more abundant source.
@If you can't melt sand - how do you make glass? maybe you should stop with just asking the whys.
When you keep asking too many questions to the point you dont put an effort to read the answers it doesnt bring you closer to uncovering anything.
Asking the why question for the sake of asking the why question is a behaviour most grow out off by the time one turns 6
This is an incredible video, so informative and well explained... but the realities are also so depressing somehow
Such a good video, makes a good understanding through history where We were and where We are now, and perhaps Where are We going, my kids find it inspiring, thanks for investing your time on positive documentaries 🏆🏆🏆👏🏻👏🏻👏🏻
This is other master piece of knowledge. My Respect and My Thanks, Pablo Amador Sosa ...Panama 2021
I am learning so much and I thought it's impossible!
A fascinating documentary, beautifully presented...the question remains: what is energy
Movement is energy
ability to do work. Anything that has energy has the ability to do work and work is essentially the transfer of energy. Each time work is done, the entropy of that system increases irreversibly.
The music on some these documentary are amazing 🥰
Quite brilliant! Thank you.
yes i like jims videos he explains in an uncomplicated way which even i can understand well most of it
Just goes to show how little we actually know about matter, life and energy. Not to discredit the amazing work of the 19th century’s brightest minds but I do wonder if one day another piece of the puzzle will be found which puts the entropy conundrum to rest.
I have never enjoyed any lecture like this in ma whole life,,,He broke down d tough Pysics into its constituents even for a carpenter to grasp easily and leisurely!,,,Thanks great Prof!
One of the best, if not the very best, utube videos I have ever had the absolute pleasure of sitting through.
20:00 The question is, can we generate the energy necessary to lift a 12.5kg weight, one metre, by heating 30ml of water by one degree?
The question IS the answer.
It's not a question. Scientists were able to equate the energy reqd for different tasks. For instance, they figured the energy required to heat water by 1 degree Celsius is the same energy required to raise raise a certain weight
Music to my ears..🎼🎵🎶🎸
Love this video, congratulations Mr. Spark

Brilliant documentary .My goodness I'm enjoying these Jim Al-Khalili documentary's more than Star Trek.
When I talk to friends and family about stuff like this,they always stare at me as if I'm weird
I feel you bro. TBH I find it amazing that more people don't think about stuff like this. I don't think we're the weird ones.
We are just too “busy” surviving under this contrived bs economy to be able to concentrate on the greater expanse. Even so-called higher post secondary university education is aimed towards the needs to survive under the edict of “market needs” instead of genuine People needs. So-called higher education is not for self edification but really glorified pseudo trade education, but it doesn’t even fulfill that.
@@TheRoland444 it's all capitalism's fault.
I too feel you bro, everyone else don't care about this
@Benaiah Ahmadinejad Muslim lesbians eh? Thats rare to find. Take my moneu
Jim Al-Khalili and these BBC documentaries are spot on. BOOM! science.
The internet is a cringe parody
makes me realize how small and insignificant we are and new perspectives on what we are able to do and keep us searching for more. lots of doors to open and each one new things to think of. For me anyway.
Thank you for this content. You have re-excited my child like curiosity to obtain knowledge. I love when I see the genuine curiosity and excitement in this shows host.
I might have fundamentally misunderstood this perspective. I mean, from their dualism perspective (order/disorder), Isn't everything moving toward order? Isn't that what the rectangular collection of fast moving (hot) atoms on the table show? The rate at which atoms vibrate spreads out ... the more spread-out, the more the system as a whole moves toward stillness and "order"?
It takes energy to create order. A metal bar was extracted from randomly spread ores, purified, and shaped into the bar. The heated bar, as explained in the video, was heated with energy. Left alone this order of heat dissipates and radiates into the cold, less ordered surroundings until an energy balance is reach, i.e. body the bar and the surroundings are at the same energy state. The bar's heat order falls away. Also, over much longer time frames, the environment will pull it apart through corrosion and weathering until it returns to its dusty ore-like starting point.
35:12 the reason we take aroms for granted is bcs Einstein proved they exist in 1905 using Brownian Motion.
Thank you! Beautifully explained
Every video about new physics or astronomy gives me the history of science. I don't want a history lesson every single time gosh
Gravity is the counter force to entropy. It compresses dust and gases floating in the universe into stars, thus bringing order to an isolated system and decreasing entropy of that system (area)
I thought it’s been said gravity isn’t a force though? 🤔
@@TaPharoahTrue that. even entropy is not a force.
Both entropy and gravity are a property of matter...any matter.
why do i prefer watching this instead of Netflix
This is real flix
Ummm. . . better than Netflix because it's infinitely more entertaining to the mind than a whole bunch of poorly written, made up crap. Just. . you know. . IMHO
The question should be: Why do people prefer watching Netflix to this?
Because you are a good human being, we are the people who define the world.
Had Netflix for a month and cancelled it yesterday.
Dr. Khalil gave a subtle, fascinating insight at 40:30. The Boltzmann equation for entropy by itself implies the second law of thermodynamics.
I believe that the order of my TV/Online UA-cam mentors has been: Carl Sagan (simply mesmerizing), Jim Al-Khalili, Brian Greene, the Closer to the Truth Series, and there are so many more. Thank you Professor Al-Khalili. Thanks to all.
30:30 "unable to think clearly" indicates ME/CFS and brain fog
The problem with Jim is he doesnt know how to not be fascinating-better surrender the full hour because you cant leave 'til he says goodbye at the end 👍
wonderful job. thanks
Jim is my favourite.
everything is energy, energy is not some "thing" out there...it is everything !
And there is nothing but empty space between each of the particles (Electrons) that make up atoms and between each atom. 99% of everything is empty space
@@stephenhunter70 yes and do photons have energy, nope they seem to defy the laws of physiccs
@@stephenhunter70 well, one could observe that even that empty space is just a perfect equilibrium of "nothing worth showing". basically, the matter is the change in this equilibrium after some timeless and extraneous interaction disturbs the surface of the spacetime like a rock would disturb a calm lake. what we perceive as matter is nothing more than the angle of the oscillating surface of the emerging waves, practically sudden and complex anomalies in an otherwise smooth spacetime. an entropy is when the ripple amplitudes progressively calm with the increase of their curvature.
@1littlelee no they don't. they seem to defy it, but no, photons do not travel at exactly 1c. nothing observable ever does.
Okay, but what is energy? This is definitely a common thing to say, that a lot of people will just go along with without thinking too much further. In a way, it's kind of a generic thing to say, so what is energy then? (hint: energy is not everything, and the next episode is about it)
@@ericgraham8150 energy is everything, that's what it is, lol. No energy = nothing exists...
I was always suspecting that energy is a scam.
Now finally someone says it. Thanks Jim.
@Southeastern777 - We are talking about energy here, not about energy consumption. Please stay on topic.
We get it by going to disorder?? sounds like a scam to me
@vladimir putin is andrei panin jfk is jimmy carter "Energy" not "Earth" is the topic here.
@Allah is Satan(Saturn); Mahomet=Baphomet You forgot one thing: you're a hoax.
Super interesting and well explained. I love these presentations! One question though, not very important but I always wonder. Why do makers of scientific documentaries tend to choose such scary soundtracks?
This is so dreamy, fantastic!
and here i was thinking entropy was disorder to order seeing as how various concentrations of energy throughout a given area will disperse in to a smooth/even distribution of energy in that given area over time
The Story Of Adds With Professor Jim Al-Khalili
Good science documentary! Love the way fusion power, the power of the stars, is at the forefront of our latest efforts to produce energy, it’s proving very challenging! In order to fuse hydrogen atoms to produce helium, a lot of energy has to be put in, but in order for it to work successfully, to be efficient physically, and economically, you have to put less energy in - than what you get out, that’s putting it in an extremely simple way! Nuclear fusion is the dream of the 21st Century, the dream solution for our energy needs.
Simply awesome. How wonderful it would be if Prof Jim was my lecturer in uni.
Dude I f****** love his documentaries.
The words "order" and "disorder" are a bad choice to express a transfer of motion at the atomic level.
It would be better to say that heat motion of atoms is transferred into their surroundings until homogenization with the surroundings. The atomic structures themselves don't change; so their order remains the same. It is the quantity of motion that disperses into the environment.
Lovely explanation
Well put. I have always had exactly the same opinion.
Brilliant explanation , congrats!
Well said. Order and disorder is a human construct.
the motion itself is a disorder, the motion of atoms is a disorder, like gas molecules when they are in slow motion, they are cooler, when they gain more energy, they gain more speed, they become hotter... this is the flow from order to disorder
Thank you I finally understand what entropy means!
