Mod-01 Lec-03 The Langevin model (Part 2)

I've been a critique to his approach in stochastic process but he is quite awesome in statistical physics. Commendable.

[@mohammedsrivastava5917]

who the hell on earth is you to criticise him?

[@nsumanth18]

He might be wrong here and there in his explanations but being a critique of his approach? That doesn't quite make sense, it's not HIS approach it's quite well established , a century old physics!

[@RenormalizedAdvait]

@@nsumanth18 His "teaching" approach. You should have understood the context.

[@lipfried]

@@mohammedsrivastava5917 Fallacy... if you are learning from him and his teaching methods do not work for you then you are 100% allowed to criticise that. People learn in different ways, look it up buddy. The same way that you don't have to be a professional musician to criticise some music you don't like...

How hard it is to give these lectures really marvelous.

@ 18:58, I think the mass of the particle does not signify the particle itself, but rather the strength of the noise acting on any particle with that much mass. Like said, it is always preferable to define the noise strength per unit mass.

நிலையின் திரியாதடங்கியான் தோற்றம் மலையினும் மாணப்பெரிது.குறள் இது வள்ளுவர் இயற்பியல் கற்றறிந்து போதிக்கும் நல்ல பேராசிரியருக்கு எழுதப்பட்ட குறளோ என எண்ணத் தோன்றுகிறது.

[@nisaxaxa123]

there is an implicit assumption that brownian particles become maxwellian at t=inf, i wonder if it true for a brownian particle in a any general type of non-maxwellian background

[@deepmondal323]

I think the central limit theorem works here...

[@bidhankhirali]

one of the greatest professors in india..

[@alexopremcak8715]

Not just in India...

[@elamvaluthis7268]

Brownian motion in water due to movement of water molecules as well as suspended particles interaction with water molecules also chemical reaction should be considered.

[@elamvaluthis7268]

Noise is because of vibration of the particles also it should exceed 20cycles per second.

[@wangshuoleon4400]

he wrote an incorrect solution of the equation of motion, the kernel exp(-t-t^')/\tau was missing in the integrant, in the first few minutes

[@deroooful]

Well, he fixed it a bit later
