Thermodynamics 5d - Statistical Mechanics IV

[@DialecticKaos]

An amazing presentation, as always.

Fantastic work!! You can get a similar result by calculating all possible quantum states in a "sphere of energy" using the energy eingenvalues of the particle in a box. It's just an approximation but I find it quite interesting.

Cool stuff!! Thank you

You are welcome.

This is a fantastic work. Super clear and instigating

[@viascience]

Thanks!

Great as always, Makes my head swim but worth every minute.

[@viascience]

Thank you.

Great video! Distinguishable atoms by whom? Would an observer who can measure different isotopes get a different measure for entropy than an observer who can't? Would there be any real world impact, or some kind of relativity-esque world where both agree on laws of physics but disagree about the amount of entropy and a whole bunch of knock-on measurements because of it?

[@viascience]

Thanks. Indistinguishable = fundamentally indistinguishable, in principle, by any physical means. If there are different isotopes, those have to be treated as separate "species" of atoms (plus the mass parameter m will be different, and this allows different isotopes to be physically distinguished and separated). As we will discuss in the next installment, the absolute entropy given by the Sackur-Tetrode equation is measurable. So, even if an observer has no mechanism to distinguish different isotopes, s/he will still measure a different entropy if different isotopes are present.

This was an excellent explaination Thanks

You are welcome.

I'm still waiting for 3rd Law of Thermodynamics

[@viascience]

It will be the next video in this series.

[@KetanSingh]

Can you please work on a special and general relativity series?

[@KetanSingh]

Trebor Thanks for pointing out!

[@narfwhals7843]

@@KetanSingh his GR series is however incomplete so far. But it is very good! Maybe if you poke him a little...

[@viascience]

A new installment on cosmology is in the works.

[@KetanSingh]

ViaScience Great! I hope it includes a general introduction of special relativity as well?
