It's because he's the man. You Tube should give more support to Sal for everything he has done to bring education to the world. I hope he wins the Nobel Peace Prize for bringing education to everyone.

Indeed, public educators bring massive impact to students all around the globe than the private school teachers! But if not trusted, misinformation could spread equally as much since their credentials are often unknown.

Thanks Sal, you're amazing :)

Draws a rectangle. "So we have drawn a cylinder ..."

When you look at a cylinder from a certain angle, it looks like a rectangle.

This is beautifully explained.

very good and helpfull videos Serie !!! thx :D

what I think he means is that the experiment itself is done on a planet or something with a strong enough gravitational attraction but it's just that the top of the piston is in a vacuum so that there are no outside pressure (from the surrounding molecules of gas outside) that pushes the piston down.

For Aeronautical Engineering, which thermodynamics should I listen? Phsyics or Chemistry? I think I should listen phsycs but want to be sure.

Nice...was having some confusions while reading blundell

he clearly said were doing this in space and were doing it in a vacuum.

Best thermodynamics video set

yes you are right,unfortunately the current system of education is based of finantial factor, if you pay you can learn, but Sal and some people on youtube bring education to everyone. happy to see that Bill Gates support the program and he recognizes something that is very dynamic

At 6:42 Sal says that the microstates are changing every gazilionth of a second. Just out of curiosity, would you say that the position and momentum of a gas atom or molecule changes in the range of a macro, nano, or picosecond?

you inspire me sal khan

Here what are the opposing forces that makes it in a state of equilibrum ??

I learned so much from this. thank you Mr. Khan A!!!!!!!!!!!!!!!!!!!!!! 🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓

Just an aside: No, you cannot define both the momentum and position of a particle that accurately, becoz of uncertainty principle

Wonderful explanation ✅

Great.

objects in a vacuum can have gravitational forces acting on them sure but the object weather in space or freefall are weight less.

thankyou mr khan

5:11 yeah but isn't uncertainty principal says that you cannot determine moment and position of particle at same time.

It's more that the more precisely you measure one, the less precise your measurement of the other.

He never said the rock was in space, he only said there was vacuum above it. You can have vacuum on earth as well...

Why would the piston oscillate?

amazing

Good tutorial

I still don't understand what the difference is, he only gave us the concept not the method of how we use and find Microstates and Macrostates. I just wanna know what the formula is when it comes to probability and Big omega formulas.

PBWeather Pro then Google the formulas. There are many students who are just given formulas in school and students dont get an explanation of the concepts of what is it that they are actually doing. You see, science is more than just formulas

4:00 Would Heisenberg's Uncertainty Principle make that impossible to do? Or does that only happen with sub atomic particles?

@sunitaapte7514

Heisenberg uncertainty principle states that we cannot determine the momentum and position of an 'electron' at the same point.

but if the rock is in space how does the rock have weight to push down the piston ?

Wow, I didn't think to ask that question. Einsteins theory of relativity would suggest that the rock and gas cylinder curve their local spacetime to create a gravity-like sensation. I doubt he wanted to invoke that logic so I'd redefine his experiment as follows: conduct said experiment in a vacuum ON EARTH where the rock has weight. 7 years too late, but I hope this helps. :)

he only said space to signify a vacuum environment.

You are correct for the most part except for a minor detail. Not all objects in space are weightless, but only in a special case they can be. An object's weight = net gravitational forces it experience from all the mass in the universe. Hence the force inversely proportional to the square of the separation distance, masses at great distances contribute less to the net force, thus an approximation can be made using the closest mass.

It is better to watch this at 2X lmao!
