To anyone watching these videos, it would be of great importance for you to know of a new feature within TH-cam.

many thanks for putting this video @ 35:50 you could say easily that f(x) in that tiny range is f(a) and the rest is, according to definition of R, equal to 1 ..So the whole is f(a)
To be honest, Hand wavy arguments confuse me... A rigorous mathematical treatment from first principles would have worked far better in this instance. Anyway, some people seem to like this style of teaching, so whatcha gon do? Wish you all the best, I’m finna head out now 👋🏽
Sir, I have a questions on pronouncing Greek alphabet, why do many physicist pronounce Ψ [sai] instead of [psi]? I believe it is very wrong as the alphabet isn't English but Greek so well educated scientists should respect other cultures.
delta del dirak all deals in a mixro system na ? why is it not possible see when we talk about galaxies than our planet is a mixro system na than will the behavior changed from that reference of dirax fun?
18 you sir diffentied it twice it given you Ke so how do we know what it will give if further diffentied also let me know how do you know it's a kinetic energy sir ....?
14 total energy is kinetic still I wanna know why we do so as due to so small mass or sir there you ignore gravity ......okay sir still is this dirak equation is not only valid micro but also in macro na than sir let me know that why we see that dinger equation do forget about the potential energy in 1D ?
31 what a function sir wonderful I liked that drawings it seems good to make Dirac graphics i like that system of drawing wanna get computer graphics for the same sir is it possible direct me .
respect to the system of discontinuity than Dirac delta function here we got so functional system as of Dirac + gaussian + graph of gaussian function so gaussian function is used in reference to wave nature n behaviour deriving cool
Schrodinger equation is a wave equation and in order to prove that, we used a plane wave solution ψ=Aexp(i[kx-wt]) Thats why its not consider a derivation because we used a plane wave to show that it satisfy a wave equation.
we do need fourier system so some equation sir we need to make some okay do know that wave nor particle is but a hypothetical system it's a function what are you making me say that it's a function so just imagine the creator first doing some random maths and He found a function n put in some computing system lo you see what He got ...oh it's a subatomic particle : party now?
I want better name to seems difficult see if wanna name mine self as kadifrandaneonineygenedia too difficult? TRY new material as zdoz dozdozd how is it sir say as abia shiffar /surfer?
im a below avg student
and this was suprisingly easy to understand for me
thank you professor
pronam neben
Good
You can't be below avg in curiosity!
For this man I passed in my physics exam. Thanks a lot sir. Without this man I'd fail
Sir ,I read the optics book written by you is very good book to understand physics properly.Thanking you sir
Please the title of book and name of author in English of course?
Thank you very much for this video sir :-) ..means a lot to a students who struggle with this topic ..Thanks once again ..!!
God of physics to India is prof.Ajoy Ghatak.
thank u sir....u r a former professor of IIT Delhi.......I m a student of the same institution........I well understood.. the Dirac delta function..
excellent methodology of teaching. Really outstanding. So lucid.
To your Industrious effort we understand well I fall at your feet.
Best lecturer in lecturing quantum mechanics
An excellent lecture on Dirac Delta function in my opinion
None can teach better than this quantum mechanics. ஆ ஆ ஆ ஆ.
I proudly feel, i understood some thing... Thats why we need a master ..
thanks sir for the video..nice brush-up of the concepts.
Very good professor. HE explained everything well.

you are so outdated
lol noob x1.75 is much better
though 6 year ago this cmnt was imp
Thanks Professor for this nice video
14:50 can anyone send rigorous derivation of shrodinger eqn
Long time no see bruh lol

Nearly a century later, Schrodinger's cat is how most of us remember Schrodinger's work. His work must be much more praised !!
These proff is too good
Your books on optics is great
Excellent.How do you remember all these things in mind?we can not appreciate you but we can prostrate before you sir.
nice lecture sir really helful..btw i love ur optics book
55:47 why the dirac delta function added to the equation
Hey what exactly happened at 22:17, I've seen this happen to people before... is that like a ministroke?
many thanks for putting this video
@ 35:50 you could say easily that f(x) in that tiny range is f(a) and the rest is, according to definition of R, equal to 1 ..So the whole is f(a)
So simply ...😍😍😍
I love the name it's attractive to speak dirak n dinğer equation
24:15 , how volume element dx dy equal to that.. can one explain plz ??
Great lecture....
"All of energy and matter that existed still exists. The actions of matter enable energy to
become manifest".
sir,I have a question..for proving Schrodinger you take a wave function psi=Ae^i(kx-wt).how it is related to the particle...
Then he transformed k(wave) into h cross p (particle)
What does the imaginary part of a plane wave represent? Why we use this particular form of wave for the derivation of Schrodinger wave equation.?
Crystal clear..
thanks for wonderfull exposition

I don't understand how mispronunciation denotes disrespect. People can never pronounce Ramanujan's name right, but as an Indian, I'm never offended.
delta del dirak all deals in a mixro system na ? why is it not possible see when we talk about galaxies than our planet is a mixro system na than will the behavior changed from that reference of dirax fun?
if electron or proton is neither a particle nor wave then what is it??
18 you sir diffentied it twice it given you Ke so how do we know what it will give if further diffentied also let me know how do you know it's a kinetic energy sir ....?
thanks for the Dirac delta function
thank you sir for explaining in such a nice way
so wave function psi is a complex or we can also write in terms of sin n Cose form ?
Thank you so much sir...
41 dirak system graph as a linear system na ?
57 we do have a lot of nursery drawing in physics 😊?
14 total energy is kinetic still I wanna know why we do so as due to so small mass or sir there you ignore gravity ......okay sir still is this dirak equation is not only valid micro but also in macro na than sir let me know that why we see that dinger equation do forget about the potential energy in 1D ?
Must appreciated work sir thank you
exp ?
good !
thanks professor
could anyone please tell me the name of the book he is using?
31 what a function sir wonderful I liked that drawings it seems good to make Dirac graphics i like that system of drawing wanna get computer graphics for the same sir is it possible direct me .
discontinuity in a function is Dirac delta function
Can you Please share the notes of these Quantum Lectures
respect to the system of discontinuity than Dirac delta function here we got so functional system as of Dirac + gaussian + graph of gaussian function so gaussian function is used in reference to wave nature n behaviour deriving cool
29 awesome I feel good in phase now but still there is fantasy calculations n I like only to do simple way let's find so
I didn't understand where the psi first came from and how the first equation psi=Ae^i(Kx-wt) was taken at the first place
Schrodinger equation is a wave equation and in order to prove that, we used a plane wave solution ψ=Aexp(i[kx-wt])
Thats why its not consider a derivation because we used a plane wave to show that it satisfy a wave equation.
24 what we are doing for?
34 you can even make a nursery boy accept the concept sir that was a mountain n a building where function seems as a crows n vultures I like that
54 taller sharper n coherent ?
Why has the wave function this kind of form (5:38)? Here is the answer:

@Mathematical sciences I have to, because I'm too dumb to understand them ;-)
8 1d plane wave awesome still I can't understand why he used so fancy symbols about de brouglie! yaa why ?
38 diraķ sign is quite fantasy symbol consider a Birsa munda bhagwan doing same derivation what would be his sign sir awesomest
I was shocked to learn you don't even need derivation skills above calc 2 to derive that equation.
Thanks sir j
Thank u sir
we do need fourier system so some equation sir we need to make some okay do know that wave nor particle is but a hypothetical system it's a function what are you making me say that it's a function so just imagine the creator first doing some random maths and He found a function n put in some computing system lo you see what He got ...oh it's a subatomic particle : party now?

thus here wave function psi graph on 47
appreciated
