This is a fantastic video. Very well done. I now understand much better where this constant came from. I am glad you took 8 minutes to explain it at the right level of detail.

This was exactly what I needed in order to piece everything together, thanks!

Fantastic video!! Absolutely! I learned in 10 minutes MORE R versus Kb than in ALL of Chnag's lousy textbook! Thank you for your superb presentation.

Thanks for the nice video.

Boltzmann's constant k is actually a repair action to rescale the Kelvin temperature to the kinetic energy of a particle that has the most probably speed.  In fact, a particle in an ideal gas at equilibrium has with the most probable speed (vp) the kinetic energy:
Ekin = kT = 1/2 m (vp)^2, where m is the mass of a gas molecule.

Boltzmann's famous formula is the entropy formula: S=k ln W, where W is the probability (Wahrscheinlichkeit) to have a particle in a particular state (place & impuls). If the absolute temperature wasn't defined earlier on the Kelvin scale, we would probably have an energy scale. 
The entropy formula would have been defined as: S = ln W, and the associated kinetic energy Ekin =  (1/2 m(vp)^2) = new temperature scale.

Found a video called Spacemind- Memory Hole. Saw a comment that said the picture in the background is of Ludwigs equation. Decided to look it up. Not into science that much or mathematics, however I am intrigued by knowledge in general.

Edit: Tbh, I do not even know if this shit even correlates to my search lol.

매우 감사합니다. 한국어 자막 까지 있어서 진짜 도움 많이 됐어요.
very thanks from korea. It is helpful and especially korean subtitles are awesome!

Thankyou so much! This was an awesome video now i am able to understand what the concept actually is?

The moment I was waiting for the explanation to begin, the video ends! 😞 What's that constant about? Why the pressure times the volume variation is linear with the molecules number times the temperature TIMES THIS NUMBER?

So the Boltzman's constant is the necessary amount of energy to raise the temperature of an atom or a molecule by 1 Kelvin, right?

Why did we have to do all the Boltzmanns constant stuff? Seemed logical to just put Na below R since we wanted the constant to take on an equal amount of smallness after the big N

I get about these formulas but, to me they seem to have circular reasoning for the difficulty of where they got their measurements from.

Trying to understand this in your second language in 12:00 is hard af. But I have done it. Thx

Why is the unit of the boltzmann constant not written J/(K*Molecule)?

do engines in hotter climate burn more oil or used more energy?

So, suppose I slap someone(not that I did), my hand has comparatively less speed compared to molecules, but it has a more mass and thus KE..., so will it cause the person I slapped to get warmer?

Why is the unit of the Boltzmann constant not written as V= td +1=0 now -1 ds-t G/r2.. .  .Velocity = Time Density +1=0 now -1 Density of Space Time G/r2.. .  .Tap the side of a round bucket of water.  . ..Because the Boltzmann constant is the bridge between probability and entropy.. .  .With electrical potential, quantum potential, and gravitational potential all linked in the One Universal process of Spherical symmetry forming and breaking.. .  .Tap the side of a round bucket of water.  . ..Because everything is formed by a surrounding 4pi Spherical inward absorption +1=0 now -1 outward emission of electromagnetic waves.. .  .All motion is 2pi Spiral.. .  .And all 3D directions are 4pi Spherically curved thus Wave Centres are everywhere relative to an infinite future of potential possibilities continuously coming into +1=0 now -1 out of existence.. .  .Now space is a division of Solidity into entropy as time unfolds C2 the second law of thermodynamics.. .  .But also in the future E2 will equal a multiplication of Volume +1=0 now at the expense of gravitational potential -1.. .  .E2=M2 C4+P2 C2.. .  .Because surrounding probabilistic Implosive Potential Energy always comes first before becoming +1=0 now -1 explosive Kinetic Energy.. .  .

Oh my god- I remember why I don't watch the Khan academy any more... They seriously need to invest in better audio recording equipment.

Inconsitent: Left hand side of equation is PV=Pressure*volume = FORCE! Then, RHS of equation is ENERGY. The whole thing does not add from START.
