Wow, thanks for moving above marks and exams-and looking at subject for the sake of itself.

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

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

[anugrahmathewprasad]

Oooo this is a step up from the usual videos. The graphics as well.. and new refreshing type of content. Me likey!

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.

If those people were living in our time, many would have called their discovery a "fake news".

[siddhantpathak]

Casually proceeded To refute the established Laws of Physics!! Daaaayymn

[srijitayadav]

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...

[abhishekpatawari]

i never knew plack constant was written H because of help

[Skeptical_Numbat]

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.*

Nice video 👍... If it's a series of videos my humble request, please upload the whole or share the link. Thanking you.

As a wonderful physicist once said (AKA Dr. Don Lincoln) " Physics is everything!"

[lorenwilson]

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.

Yo man I rewatch this video infinite amount of time

[murallivengadasalam]

More videos on these scientists who brought forward modern physics

[scottmerritt]

I highly recommend reading Thomas Kuhn’s book Blackbody Theory and the Quantum Discontinuity.

[rgudduu]

Made me shiver w amazement. What wonderful brains those!

[Kvltklassik]

Pronounciation of Kirchhoff - on point
Pronunciation of formulae - on point
Pronunciation of Planck - Plank -_-

[laurendoe]

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.

I am just waiting Mr. Planck playing with his cool spectacles
