Wow, thanks for moving above marks and exams-and looking at subject for the sake of itself.
That's because it's stolen content.
I mean if they have taught me at school that 'h' stands for help it would have been more interesting, relatable and easier to learn this
like you need to know why the letters were chosen for each equation to be interested in physics
jesus how vapid can you be
I agree, knowing the background to the "unnecessary" aspects of physics can add to the enjoyment. I also did not know that the "h" came from the word "help," but am glad I now do.
@@touristguy87 He literally said, "I mean if they have taught me at school that 'h' stands for help it would have been more interesting, relatable and easier to learn T*H*I*S" ... meaning, about Plank's constant. You're the one who's vapid.
Most likely 'Hilfe' , help in German
@@asicdathens Yes, the video did say it was the German word for help.
It's actually insane that this was discovered 100 years ago and now college students learn this their first year, and even plenty of high school students do
I like to think of it the reverse way - it was discovered 100yrs ago and yet 99% of the population doesn't know about it. It should be taught at secondary school
@@bigsmall246 this is pretty complex stuff tho
I'm a mechanical engineer, and I don't fully understand it
Alot of graduate students dont
@@ab3040 it's really not that complicated. The underlying quantum mechanics are not fully understood, but the ultraviolet catastrophe itself is pretty easy to understand
@@bigsmall246 yeah that's what I mean
Quantum mechanics is tough
Unlike "normal" physics we can't see it or test it by easy means
History is full of bad jokes, I suppose
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.
Oooo this is a step up from the usual videos. The graphics as well.. and new refreshing type of content. Me likey!
Please use accurate *Scientific Nomenclature* when referring to *Scientific Experiments.*
For example, at [1:20] *Planck* did Not put his *Theory* to a test, he put his *Hypothesis* to the test.
A *Theory* is a highest, most robust conceptual explanation of an aspect of science, comprising of multiple *Scientific Laws,* *Facts* & perhaps thousands of disproved/proved *Hypotheses.*
Hey, no fair: TH-cam has a reputation to maintain: idiocy, inaccuracy, laziness in production. Physica is working hard to maintain that reputation.
@@TheDavidlloydjones- no, the idiocy, inaccuracy and laziness is the job of the Republican Party.
If those people were living in our time, many would have called their discovery a "fake news".
i never knew plack constant was written H because of help
I am in 11th standard and it is taught is in very monotonous way.
Thanks to this video for actually showing the past.
Edit: Idk why there is a war going on in my comment section. Guys chill...
@Nuclear Nadal but syllabus are vast and we can't study continuously long to cover them
@Nuclear Nadal When you just study for exams and marks you loose the curiosity to explore further, even if you do you feel you have wasted your time.
Indians have discovered this 4000 years before Plank did .
Read vedas . The quantum physics is derived from the vedas and the schrodinger equation is there in the upanishads 10,000 years before (or more than that) schrodinger came on earth

@@chitrangror8145 it's true that Hinduism has the most scientific information not everything you say is true. Rishis of old times were masters of philosophy than actual science. Only few of them did become scientists and mathematics.
And many scientists like Oppenheimer took inspiration from philosophy of ancient Hindu texts than science.
Casually proceeded ....... To refute the established Laws of Physics!! Daaaayymn
Nice video 👍... If it's a series of videos my humble request, please upload the whole or share the link. Thanking you.
I think the birth of quantum mechanics rather had its roots in two other experiments, both of which Einstein explained. These are atomic spectra, and the photoelectric effect. Einstein explained the spacing of the lines observed when light from an excited gas (think a neon lamp) is passed through a prism. he used Plank's constant in the equation, showing that plank and he were correct. This proved that energy in the electrons around an atomic nucleus is quantized in steps, rather than being a continuous property. The second experiment, how a photocell works, also proved that the energy of a photon is quantized.
Schwarzschild played a part to. Amazing what these men achieved with such basic equipment. What could they have achieved with a modern lab today?
Yo man I rewatch this video infinite amount of time

@@chitrangror8145 , cite the Veda verse number if u know
@@chitrangror8145 I am saying this as an indian, i am also proud of my culture and ancient works, but it's really not good spitting anything without knowing it properly, as it creates a bad image for all indians like we are arrogant and spit bs because it is reality that most of us don't know a damn about our culture so it is meaningless even if it was written in veda but we as an Indian have failed to develop that concept further besides we have abandoned those works. So we can't whining to other people to acknowledge our work besides we should work on our ancient knowledge and develop that or connect those knowledge with modern science etc but until then this false pride could lead us to nowhere as a community.
I highly recommend reading Thomas Kuhn’s book Blackbody Theory and the Quantum Discontinuity.
Good experiment

Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature.
I would love to know more about the device used. Do you happen to have a reference that shows the details?
Quantum Mechanics Is the Most Interesting Subject .....

I was hoping for something a little more in-depth - such as explaining in more detail why the "ultraviolet catastrophe" was so catastrophic to the theories at the time.

Where does unit (h) come from?
To solve the blackbody problem, Max Planck introduced the quantum unit (h ), (h=Et ).
The element (h) did not exist in physics before.
The unit (h) does not come from formulas or equations.
Planck introduced h-unit from the "heaven".
Planck introduced the unit (h) intuitively, phenomenologically.
Planck introduced the quantum of action "without recourse to explanations,
metaphysical assumptions and traditional philosophical questions".
For many years, Planck tried to find a rational (classical) explanation
for his h-unit, but without success.
We don't know where the unit (h) came from

It was also spelled wrong. Someone let their auto-correct turn it into a wooden ship part. for the sound... Now say it with me... Johann Sebastian Bach.
Now I am bach into perspective.
It's a video related to physics not english language, so who cares.
Planck was a German speaker. h = Hilfe!
blackbody radiation was the central idea and enigma that led to this discovery. Also, Planck used the ideas earlier developed by the likes of Boltzmann, Maxwell, Rayleigh, Wien, and Stefan.
That video literally explained nothing 😞
It explained what it states in the title. That is all. You expected an actual video about the constant itself to be that short? All this did was describe how he got into the work that resulted in the constant, just like the title declares.
In 1905 a Zurich physicist 😂😂

Nice video, could anyone tell me the name of the background music.
Thank you so much. Did Plank assign his constant the value of roughly 10E-34?
I was expecting Einstein's cameo...
Einstein is overrated. His photoelectric effect is nothing more than using Planck's idea of energy quantization. He also gets way too much credit when he did not even set up the experiment himself but only interpreted the result.
Spoiler Alert: this video contains no reference to Planck's Constant, only vague handwaving in the direction of the origin of the quantum mechanics of light. A shoddy piece of work overall.
Add in the misspellings and mispronunciations and it surely ought to be taken down and redone.
...ths real issue here is that the assumption that a black body spectrum is made up of a continuous range of light frequencies is just plain wrong. But the assumption of a range of discrete frequencies doesn't make a big difference. The total output energy is still the integral of all the energies of all the frequencies in the output spectrum. You would just need enough frequencies for the output energy to be effectively infinite. Much as lightspeed isn't infinite but over a suitable reference of space-time it is effectively infinite. If you are operating on a reference frame where light takes a detectable amout of time to cross then you have much bigger problems. So the issue really is to sustain such a reference-frame.

The origin of Planks constant? Turns out it was this fellar named Bob Plank. . .
Jarvis?
Max Plank yes but not Einstein... most of the theories and equations of Einstein's including E=mc^2 are copied from others...
All new ideas are the union of two or more similar or competing ideas, transforming multiple specific concepts into a more generalized whole.
To think of any lone scientist as being the sole-contributor of any discovery, is just plain silly my friend:)
Series name plz
Einstein finally developed a theory about space, and it was about time too!
The screenshot makes him look like a Disney villain.
0:30 I think that should have been "light from heat", not "heat from light".
this does not explain Planks Constant...or its assumptions
Look at the title. It explains the origins of it, just as the title states. Explanation of the constant itself is a much much deeper subject than a quick video could cover even a small QUANTity of.
There was no keer-shoff involved. The German Kirchhoff has two H's in his name. They belong to two different syllables, the kirch one, which ends in a guttural, often written KH, and the second one, hoff, which starts with a perfectly normal hoh sound: keerkh hoff.. No ch as in church, no sh as in ship. Guttural kh, straightforward h.
Dunno who this Kirshoff fella, at 0:38 might have been.
And Max Planck (sic) had a much softwer A than any english piece of wood.

You described current imposed belief. My grandfather was working with Max Planck. He was a real scientist. A theoretician who would only publish after experimentally proved the result of his theory. Max Planck experimentally proved black body radiation is emitted in discreet unit (photon). Sangy (Einstein) took his work as he did Olinto De Pretto calories= mv2 and others and presented it as his. So grandfather stopped his work and left Europe because Sangy was signed by Trojan project..

For those of you who don't know the value of h
h =6.626 × 10^-34 J s
No it isn't. It was finalized in 2017. The exact number is 6.62607015 X 10^-34 J s (from NIST). Unlike pi, the digit count is low, so no need to chop it off and unlike loose calculations like those in say electronics where rounding off is not a problem, here, the exact number is what should always be used since we have it and we know it. That places ANY error occurrences elsewhere in other data elements.
@@cosmicraysshotsintothelight I use 6.6
@@rahuljoshi3338 And that throws off your current and downstream calculations.
Nice attempt at a funny ribbing though. Pretty transparent, since if you are aware of the number and use it in your work, you would not be rounding, much less to that level. You could change your name to RaFool. Then I would have certainly believed you.
@@cosmicraysshotsintothelight i think rounding is what used for approximate results. Either you are pretty cool with head scratching floating point calculations or you are just not exposed to these yet!!!

@@rahuljoshi3338 Your language indicated that you are very young. I was reading the CRC handbook way back in '72, when it was actually used, and that was likely before even your parents were born. Your "learned it at the disco" vernacular gave you away for just what *you* have been thus far exposed to.
And Oh, looky... no more handbook needed for referencing as I have this sweet supercomputer level, Internet connected smart phone to look things up on and even do SIMPLE, yet precise calculations on. Oh my! What will I become!?
Einstein said never memorize anything you can look up. I'll extend that to not performing calculations in my head when I have a readily and handily available device for it.
Starting on Lotus 123 on an 80 x 25 character XT with a 150kb/s Arcnet network card on it back in '86, I think I've got the 'when to round off' thing covered. And with the mantissa available to me for advanced calculations, I think I'll remain as precise as my scratched head allows, and do my rounding on the final product... maybe.

First off, you need proofreaders at the very least. Your sister or something... anything. You spelled Planck and Planck's wrong both in the graphic box at the vid beginning and in the title. You should be forced to walk the plank for that. :-)
Then, the number is now finalized and is not that long a number, so you should give the whole thing, not just a 3 digit partial. it is 6.62607015 X 10-34th Js.
I don't see here where anything was 'discovered' nor proven..
Can't you make it in hindi
Didn't mention Pi, which is an important part of the equation. Gets a thumbs down from me for that reason.
Pi actually isn't important in the blackbody radiation law, or even in relating the energy of a photon to it's frequency. Pi only shows up if you want to express the frequency of light as angular frequency, which is the exact same thing with a factor of 2 Pi, or if you express the momentum of a photon in terms of angular momentum with the reduced plancks constant. But it's the exact same thing, just a factor of 2 Pi for mathematical convenience.
@@ShaneClough Thanks for explaining that. I'm interested in how the Planck length is "the smallest unit in the Universe" and have been working on a base twelve version of Pi which reveals the solution to the challenge of rectifying an "infinite Pi" and a "shortest length". Explanation lies in the geometry of the circle from a base twelve perspective.

You need to walk the plank if you can't spell Planck.
This "explanation" of the origin of Planck's constant is completely wrong. Planck did not believe or state that light (electromagnetic radiation) was quantised. He only assumed that the electrons in the the wall of a heated black-body container, during the actual process of emission, required quantised energy, but that the subsequent radiation of the light continued as waves. He made this ad-hoc physical assumption simply because he had introduced the constant `h` as a mathematical trick "in a last desperate effort" to obtain a radiation spectral formula which fitted the observations by the experimental physicists (not by Planck himself as the video states). Then, in 1905, Einstein criticised Planck for not providing a meaningful physical explanation for the formula. And Einstein proposed his famous theory (which he himself called "revolutionary") that the radiated light always consists of quanta (later called photons), and showed how this led to the correct radiation spectral formula. However, for more than ten years Planck did not accept Einstein's belief and theory that light radiation was quantised. Therefore, Einstein was the first physicist to introduce a quantum theory into physics, first for radiation and later for specific heats and other phenomena, even though Planck had earlier introduced the constant 'h'. Planck himself later explained that he was very conservative by inclination, and that he found it difficult to make truly revolutionary assumptions such as Einstein's, that all matter and radiation is quantum in nature.
Bullshit ...i dont get all these lies around Plank.
He was the first one to postulate the quantization of energy ,and did it in an experiment and gave it a mathematical equation. Einstein recieved the Nobel Prize for explaining the photoelectric effect.
But Plank was the first one to observe ,deduce and describe the first bits of the quantum world
He recieved his nobel Prize for discovering the energy quanta (and for making the term quamta popular) ,without him Einstein wouldnt have been able to gain his Nobel
