This has to be possibly the most professional and well put together physics channel on CZcams. From the animations to the logical descriptions which make difficult concepts make sense! This has given me so much to write about for my formal report on Black Body radiation.
Thank you!
Math teachers: Zeno's paradox is easy. You can overtake the tortoise because we have calculus.
Quantum Physicists: WE DONT EVEN KNOW WHERE YOU ARE
An underrated comment
You can only describe how the overtaking would be approached and that overtaking would take infinity... as well as what quadrant one is overtaking in.
The elements that go zero in calculus, don't. So the resultant answer is a little bit off by the Planck's Constant.
@@Sunspot1225. Planck suggests reality is digital! :)
We especially don't know where you are if we know you're running at a speed.
Im a highschool graduate with no schooling in Quantum Physics but I Have a real passion for it and these videos are absolutely fantastic! I was never good at math but I understand the theories very well!! love these videos!
Don’t give up. I am horrible at math and school in general. I am self taught in physics and was able to work in an engineering capacity despite not having a real formal education. I am a student of science although I have no aptitude to being a student in school.
Sorry, but you don’t understand any ‘theories’ without the math. The day you think you understand quantum mechanics is the day you can be certain you don’t
Same. So weird never took it outta all the college I've had
@javiercastro8466 how did you do that because same. I would always get c's in math in hs but inly passed because I would try and get tutored. I tried 4 times to pass algebra in college Then got a's in a different college because my math professor taught me how I learn? I figured out I have dyscalcula because of his genius
I just love how popular this channel is. Many times I don’t understand what’s being talked about but I always watch every vid. Sometimes multiple times.
After watching these lectures i really feel science has scratched the surface, there's so much to learn, and thanks to channels like these, we are getting to question again and wonder at the world around us, a trait long lost with childhood!
I love watching PBS, it makes me feel more intelligent than I am.
-Woobywooo dont sell urself short man.. the fact that this type of content interests you instead of honey boo boo's channel already sets u apart from 90% of the population.. also reading books on these subjects are a great way to compliment these videos to help comprehension.. another great channel is Isaac Arthur's channel.. he talks about more hypothetical concepts like the Fermi paradox, Rocheworld's, transhumanism, Dyson spheres, etc.. dude is very smart, and doesnt include so much math and science.. its more conceptual.. check him out:)
Cheers Neo, I will most certainly check him out! I have a lot of theories myself but I lack the knowledge of actually proving them right ( Or wrong ). I will hopefully change that in the future! Either way, these video's are fascinating
Complement.
Wot! It does exactly opposite to me!?
ya id like to see them show us how to use some of the equations, that would be sik!
So. Einstein discovered dark energy almost a century ahead of everyone else because his math wasn't working out without it. Planck discovered quantization of light because his math wasn't working out without it. Do I see a pattern here?
What do you mean?
If you wanna get technical the dark energy is all around us, it's called gravity. It's the lack of gravity that creates anti-matter, cause no gravity is there to keep it intact.
I'm off my rocker, let me just get back in my seat
So you're implying this was all made up because someone just had to invent new stuff to make their theory work? Then how do you explain that we can actually detect these quantum phenomena? For example physicists are having trouble making computer processor chips in smaller scales, because the quantum tunneling effect makes the transistor gates randomly not work.
@Bob Harris Well, technically, they are. Doesn't mean they can't be true. We know for a fact that the h constant is good, Planck just plugged it in to make the theory work.
And we get an F when our math doesn't work out........
Imagine just accidentally figuring out one of the universal constants.
WoWoWoWoWoWoW
I don't agree, Its only a constant relative to what is needed to make measurements. The actual constant doesn't exist. Space time has no segmentation, it is analog, even if it can only be perceived digitally... in fact all real numbers are digital... we would have to describe nature with only unreal numbers to achieve a decent representation of our universe.
Nothing is random they spend their lifetimes doing and calculating things . I repeat nothing is random
Hum must not be hard to imagine; aint there a LOT of Chance accidents around here? Primates sustain on accidental figures...
@@Reach3DPrinters I think it has to do with different states of consciousness Do animals or insects have what is needed to take a measurement in the way we can take a measurement of something.
I'm a PhD in Materials Science. I also had a phenomenal Materials Properties course as an undergrad. This was still one of the best ways of diagrammatically showing the origins of the UV catastrophe (at 6:43)
There have been a lot of great episodes here, but this one is by far my favorite. I like hearing the history of the math and scientists as much as the science. The story about Plank and him going "huh, try this" was really fun. And I really like the integration of the tortoise analogy with BB radiation and Plank length. Everything just worked for me :D
Its a great explanation, probably the best I've seen.
Max Planck may have never imagined that his constant would be used in 2018-19 to define New/Quantum SI unit of Mass (the Kilogram Kg).
Although it might sound exaggerated IMHO, this "math trick" was the single most important moment of the entire history of Science.
I feel like this video doesn't give Planck enough credit. Trying out lots of different ideas to re-create a distribution is not the same as mashing random buttons. For one thing, all buttons have a chance of getting pressed, but not all ideas (such as dividing the whole equation by 0) are valid.
Also, it makes coming up with all these ideas sound a lot easier than it is.
Lastly, his result was caused by trial-and-error, not pure random chance.
Yes the video did not give Planck enough credit. He was studying entropy and a student of Boltzmann's work. He too stood on the shoulders of giants.
Planck was completely brilliant. He also understood the full impact of what he'd just done, because he HATED IT.
@@KipIngram yup, it wasn't until Einstein believed him that people saw it as fundamental and not just a classical puzzle. Enter Quantum Mechanics, then Einstein hated what he'd done! Bohr was really the one we needed, a true believer in h and all of its consequences.
When bro actually studies 8 hours a day :
Thank you so much, PBS Spacetime for these videos on the quantum realm! They are so clear and concise! I'm very much enjoying these!
Actually, quantum mechanics forbids this.

Favorite line of the video: 9:22 "As usual, it took Albert Einstein, to..." Lmao
*The best* channel on YT!! Thanks for another video that enlightens us all on the beauty of the universe!
*Q:* _Is there an independent experimental method to measure the Planck's Constant?_
I ask this because for what I understood, they calculated it based on previous measurements, so it was more like a math trick.
One can actually derive Planck's Constant from the photo electric effect itself.
+Lorenz Zahn Exactly, we did that in 12th grade.
the photo electric effect can measure the planks constant by an experiment where a light source is shone onto a specific metal which cause some of the electrons to be ejected from the metal. there will be a certain voltage within the circuit which you can measure just by using a variable voltage supply and so because of the equation V=J/Q you can rearrange to get the J=VQ where J is the minimum kinetic energy that the photon needs to overcome the voltage which is also know as the stopping voltage. once you know this you can use the equation E=Hf-Ø to work out planks constant where E is the kinetic energy of the photon, F is the frequency on the light and Ø is the work function, which is the minimum energy that needs to be given to a photon to be ejected from the surface of the metal, hope this helps
MultiMdave
What was posted here is not even theoretical physics, it's experimental physics. Theoretical physics is where it gets completely crazy and where without very advanced math skills you will despair. (trust me, I'm studying Physics and Astronomy in Bonn University)
But why is plank's constant called "h" ?!
Damn I love this channel!
Yeah this dude is so intelligent it's frightens me.
not to hate on him, but with enough time and research anyone can become as smart as him. it's one of the more awesome parts of being human!

i can't stop repeating it either! Best content on the web as of today.
Totally agree!
Thank you for (1) a clear, concise and comprehensive explanation of exactly what the "ultra violet catastrophe" was and how reformulating conventional wisdom (the Rayleigh-Jean Law) by incorporating Plank's constant to form the Plank Black Body Law, quantized the relationship between frequency and energy, resolving the issue, (2) for confirming that the flaw in the Rayleigh-Jean Law was fundamentally the same misconception as that leading to Zeno's paradoxes, and finally, (3) for tying it all together by showing how the fallout from Plank's idea essentially resolves both issues not to mention giving birth to QM. I also appreciate seeing the actual Rayleigh-Jean Law & Plank Black Body Law. Understanding the history is a necessary first step toward understanding the result. Extremely well done!
The BEST episode. Never fear being silly!
"I'm glad we could help you guys entangled"
holy crap that was the most wonderful geeky thing I've heard in a while XD
As they say.. I'll science anybody I want
He should have completed saying "not in a quantum entanglement".
That moment at 9:40 was a "lightbulb" moment for me. The explanation is amazing here, well done with the video!

Albert Einstein once said that if you want the smartest physicist go see Tesla.
"I'm glad we could help you guys get entangled"
Keeping education Classy. Thanks, that made my day!
VERY HARD PROBLEM
“As usual it took Albert Einstein”
www.amazon.com/Albert-Einstein-Incorrigible-Christopher-Bjerknes/dp/0971962987
The name "Einstein" evokes images of genius, but was Albert Einstein, in fact, a plagiarist, who copied the theories of Lorentz, Poincare, Gerber, and Hilbert? A scholarly documentation of Albert Einstein's plagiarism of the theory of relativity, "Albert Einstein: The Incorrigible Plagiarist" discloses Einstein's method for manipulating credit for the work of his contemporaries, reprints the prior works he parroted, and demonstrates through formal logical argument that Albert Einstein could not have drawn the conclusions he drew without prior knowledge of the works he copied, but failed to reference. Numerous republished quotations from Einstein's contemporaries prove that they were aware of his plagiarism.
They have studied Einstein's brain and the folds in it are much deeper than a normal brain
@@MegaBaddog Nobody cares. Anyone who has read a book written by Einstein knows your comment is bullshit
@@MegaBaddog well thats how science works buddy. We copy the work of others to make an even greater statements to understand the universe
@@Thundralight nice comedy
that was great. I love going back and watchig these. New, or as a refresher, a seriously good watch.
My university professors never explained Planck's constant as well as this.
We just learnt the formulas to pass our exams - how bad is that?
Institutions are dying. Society probably collapsing and rebuilding because of the internet disruption. Damn my student loans!
Hopefully your lecturers were better than mine & as good as this CZcams video?
Depending the class or classes you took, it's not _that_ surprising. They're trying to fit 400 years of science into a semester or two, so the history and justification for the physical laws sadly gets left out sometime. I'm not sure why that's acceptable: it seems better for entry-level chemistry/physics students to cover a little less material, but understand where it comes from.
If you majored in chemistry or physics and your professors didn't cover the blackbody spectrum, the ultraviolet catastrophe, Planck's solution, and give you problems to derive the formula for yourself, shame on them: this is something that should be covered in a thermodynamics or intro to quantum mechanics class.
@@jorymil I always wished lecturers would give a heads up on what we were going to cover next time. I find it much easier to learn something "new" when I've had a chance to introduce it to myself for a little while first. Brand-brand-new concepts usually overwhelm me somewhat.
@@conorm2524 Preach it, sir! A good syllabus can certainly help with that, but providing that context in-lecture, almost like a TV serial, certainly would be helpful sometimes. Depends on class size and format, too.
i am so grateful to god that he made me stumble on this channel . as i am an indian student the people from my country who create videos on this stuff are all occupied by JEE , NEET AND CBSE no one is interested in science rather all r interested in marks . thank u for this beautiful explanation
Which god? We invented so many of them. Especially in India. ;-)
Awesome!! That was the best explanation of Plank constant since my high school, I never got very well this subject. When you think of a limit of the quantum scale, really simplifies it. Thanks
Wow, I think this might be the best episode yet! Can we get a part 2 on the origin of quantum mechanics?
Absolutely brilliant episode, I was wondering where from this constant came from, but the process is just amazing!
"When he (Planck) came up with in his moment of desperation..." A powerful statement!
LOL'd @ " *_Space Time and Chill_*" / "I'm glad we could help you guys " *_get entangled_*."
who wouldn't get entangled to science?
This was a mindblowing explanation to the tortoise problem. Never thought about it from a quantum perspective!
These videos are freakin' awesome. The host does a great job of making it easy for a non-scientist to understand.
Finally a well put together science video, and i love you pace, keep it up brother!
These topics are so... badly unexplained in most other places. This channel does an absolutely perfect job of making it understandable.
Our hero wandered down the mean streets of Blackbody Radiation and stumbled upon the Ultraviolet Catastrophe. The hero thought he must have taken a wrong turn somewhere in the past to be forced to confront this horrendous monster. The Ultraviolet Catastrophe wrestled aggressively with our hero. In a moment of desperation our hero discovered a weapon. He took Planck's Constant and used it against the Ultraviolet Catastrophe. Then out of nowhere a friend appears and blasts the Ultraviolet Catastrophe with his powerful laser the Photoelectric Effect. The friend helped up our hero and both were awarded medals for their achievements. At that moment everything in the city had changed...
Now we need a "Far Side" illustration.
Thank you PBS for another excellent science episode. The video production and story telling is built beautifully and logically so it's easy to follow and understand . Excellent, thank you .
you are seriously THE BEST, you bring me back to the school desk, when I was discovering such things for the first time, and then reading on books and science magazines, watching Carl Sagan on the tv... amazing
Love this channel, can't wait for next weeks episode!
why are YOU here
@ok What kind of doubts? You dont wanna tell us you belong to the Flat-Earthers

I had to pause around 2:00 just to appreciate how amazing this is, my mind is blown! I haven't gotten to take any quantum mechanics classes yet, but now I'm even more excited!
You want to take classes in quantum mechanics based on CZcams? Anyway, 3 years passed since your comment, I hope you somehow made it.
"...help you guys get entangled."

If Space itself is expanding, does that mean that the Planck Constant of that space is expanding as well? If not, does this imply some kind of universal framework of distance?
No, because ħ doesn't really pixelate position, it pixelizes the so called "action". If you fix momentum, this is equivalent to position pixelation, but that's not fundamental.
Also, note the difference between "position in space" and "spacetime" itself. Nobody knows how to quantize (i.e. pixelate) spacetime, but in any case expanding space would probably just mean more pixels and not larger pixels. Planck's constant is constant.
Great question, and great answer!
Conservation of energy relies on the symmetry of your system under time translation (see Noether Theorem).
In a system that is not time translation invariant, eg expanding universe, energy doesn't have to be conserved.
The plank constant is not expanding. Only more space is created.
No cause it's a constant, doesn't matter if space is expanding
The Loop Quantum Gravity theory basically describes a quantized spacetime with a granular structure. We're a little far to being able to prove it, but it's a good theory in my opinion.
This is like the first PBS spacetime videos I've understood... Feels like I just ran a marathon...
Awesome. thank you very much for this very educational video (the flow of words is correct, the tone is not monotonous, the verbal and non-verbal languages are adapted, the subject of the course is very well mastered, the sound and video are qualities ). I had a nice and informative time.
Wow, this video was really easy to understand, the videos about the space-time curvature equasions were a lot harder for me to understand. Really well explained! thanks.
3:03 When he says "Science fact" I immediately remember of Beakman!
Nothing is accidential. Results of their whole life devotion and their curiosity are enjoyed by us in various ways
I'll have to watch this a thousand times to really understand, 'cause my brain was collapsing. When I didn't understand some word I forgot it until I could search, so the concepts that are not so easy didn't get in my head :( But I'll try again anyway, the channel is awesome
What happens if you increase the temperature of an object to a point where the wavelength of light it emits is smaller than the Planck length? Is it impossible to increase the temperature any more?
that's where currently known physics breaks down. A wavelength of planck length has such amount of energy, that gravity becomes comparable with other physical forces and we currently lack a theory which would describe such state.
KohuGaly is right, our understanding of physics breaks down at that point; your object would have the Planck temperature. But the energy density of such a thing would be such that it would have collapsed into a black hole way before that point.
look up "Kugelblitz"
That's not possible. In so many ways. Firstly at a temperature far below that 'pair production' causes hot objects to start emitting electron-positron pairs as well as EM radiation. Keep pumping in energy and 'electroweak symmetry' is restored which stops photons and the electromagnetic force being a thing entirely. Keep pushing past that and a few billion times the Planck-photon length the energy density is so high that any bulk mass will collapse into a black hole.
Masses with de-Broglie wavelengths on the order of the Planck length are possible, at least in theory., they'd have some interesting properties in regards to measurement.
The temperature of the big bang doesn't exist because the effects of the hottest temperature is equal to the effects of the coldest temperature.
There is also no need for a 'temperature' at all at the moment of the big bang because temperature itself is a type of measurement. You cannot 'compare' a single entity against another entity if that 'other' entity doesn't exist yet.
i keep watching these videos thinking i'll get smarter.
so far nothings happened
As much as we try to pack into these episodes, you're not going to learn quantum mechanics from a CZcams video. However you can gain some insights to guide further reading and further watching (and re-watching).

Thanks for explaining how planck's constant was computed. I have wondered about that for 55 years.
This channel is great for the explanations of stuff I will never study from the maths perspective but have infinite interest in. Yea math is everything and everywhere in astrophysics but it is also easily explained with language and I love that!
The concepts are all around us and there are as many ways to communicate an understanding of the universe and celestial bodies as there are ways to perceive our surroundings and conceptualize an attempt to define their structures.

How are people already commenting? The video was posted about 7-8 minutes ago yet it is 15 minutes long!
Because for some reason being the first to comment is some sort of achievement for people? It seems trivial to me.
Didn't you watch the episode? The tortious can be overtaken, at the quantum level. Thus, comments can precede the video, at the quantum level of course!
+Peter Gimeno I'm sorry, but the comment section of this video does not look like the quantum level to me.
+Colin Carmody Yes. Apparently it lacks humor too.

los1wochos bs. Pr and money to hide etherium. So much wrong in GRT and SRT, but it comes by steps. When you make wrong assumptions, your theory can’t be right. Another ultraviolet catastrophe is about to happen, if not that we have crisis in physics already.

That's actually incorrect.
los1wochos Indeed! ........🤔
@@nickieshadowfaxbrooklyn5192 Wut
Planck's approach was to analyze the entropy of blackbody radiation as a function of energy. To make both high-frequency and low-frequency data consistent with the Second Law of Thermodynamics, he included an additional "guess" term proportional to the frequency (hf); this results in Planck's Law. Planck's subsequent application of Boltzmann's Statistical Mechanics to justify his guess then led to his revolutionary conclusion that the material of the walls emit and absorb radiation in discrete quanta.
A paper titled "Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler (7/25/08) gives a nice discussion.
shout out to your graphic and animation artists, this is job well done.
"Einstein saved the phisycs as usual"
Damn, that guy is the RL superman of nerds.
Except that time when quantum entanglment won.
So, a full round circle of seven years rediscovering advances im physics brings me back to pixels, like whaaa?
It's like welcome back to Matrix, Neo, except this time the pixels are spinning, rotating (referring to Higgs particles) and there is more to the whole rabbit hole thing
Thanks for the perfect explanations. You are an excellent communicator of concepts that are truly out of everyday life.
I am just an engineer but with a degree taken 30 years ago. My physics texts lacked a lot of things that are now taken for granted.
In my time, exoplanets and higgs' bose were not discovered and it was still almost science fiction to talk about black holes and multiverse.
Personally, I believe that if we can study and fully understand the fabric of space at the Planck level, then the human species will be able to manipulate gravity and also allow us to travel among the stars in the blink of an eye.
Thanks again and keep informing us.
