I would like to add that through Ghatak sir's lectures,Prof Shankar's lectures, Prof Lewin's lectures and Prof Balakrishnan's lectures I have learnt how to teach physics to university students in a far better way than usual approach.
Even the weakest student will be able to understand quantum mechanics from these lectures.A grand thankyou to you Ghatak Sir.I wish I had more teachers like you during my university days,yes we also had some good teachers but Ghatak Sir's approach is very special as he does everything in lot of detail.
I am absolutely agree with Pradeep Sharma. Dr. Ghatak's Lecture is really fantastic and understandable for such a man like me who has an engineering background, but is pursuing a Master degree in Physics and dream to get a Phd degree in Physics in some American University. Thank you Dr. Ghatak and go on with your lectures. Greetings from Peru.
Really great lecture by sir and after discussing evolution of wave packet with time then animation is quite good. Best lectures on QM. Everyone QM lover join this lecture series.
lecture is great but he didn't explain in detail ...like what does this wave function even mean? how this represent a particle ? what we mean by localized here ?
please make a video over the spread of gaussian wave packet .... because i could not able to evaluate the integral for psi (x,t) on my on... its very hard. please make a video tutorial how to evaluate that integral and simplify
try to use completion of squares and start by naming constants right from the initial steps,so that the expression don't look dirty It is not hard,looks dirty But done with care,is easy:)
Einstein said if we are not able teach science to a 5th class Students it means nothing... And here every function is going on why not explained... integration not explained... Why we are doing so much calculation not explained....and if an IIT faculty not able to make understand the concept then I am in doubt who will
@@jacobvandijk6525 That's why the given solution is a general solution. A plane wave is a solution but not normalisable. He took the superposition of infinite plane waves as the most general solution. He then proceeded to give an example of one such solution which is a Gaussian wave packet. He didn't say it's the wavefunction derived from SE but just assumed a wavefunction as example. All QM textbooks do that. Am I missing something?

Patience knowledge explanatory skill dedication to physics embodiment of physics this is the speciality of this professor.

I am surprised love you sir ❤❤❤❤❤❤
What is meant by finding the momentum? Isn’t momenta a calculated thing?
This is beautiful
Unparallel lectures blessed by Iyyanarappan Tamil country God.
🤣🤣god ....really😂😂😂
Thankyou sir.

he just taught us maths behind this

Wah
Sir🥺🙇♂️
Thank you so much sir ☺️☺️☺️
Legend
he is not explaining his motive behind taking each functions very clearly

Holy Crap!
Crap!! Why??
@@alokkumarchauhan3305 "Holy Crap" is not necessarily a negative expression.
@@jacobvandijk6525 Where did he claim that? He said that if we knew the initial wavw function, we can solve.
@@farooq8897 There are no initial conditions for a free particle.
