Sir, you have summarized so nicely, the heave of sigh at the end of the lecture was so appropriate. Jokes apart, I don't think anybody has explained this weird stuff so artistically, I am amazed at your effort of making us to understand. No wonder you have chosen the name of channel as "Love of Physics" . Please post many more videos.
Best video lectures of quantum mechanics on UA-cam ever🥹 finally jaise mujhe padna tha vaise padhane wale koi teacher mil gye...ur love and passion for physics every day motivates me to understand physics deeply.i can't imagine how much hardwork and time you have to put for making these videos.May Krishna ji bless you sir 😃u are an inspiration for me

Man these lectures are work of art I can't imagine how much work goes in creating these lectures they are some of the best lectures on this subject out there thank you so much 😍😍😍😍😍
I really wish We had Teachers like you sir.... You really made this difficult topic extremely easy to understand..... Thank You so Much sir... Amar pronam neben 🙏🙏🙏
please don't stop making these videos pleaseeeeeeeee just keep on going till the starting QTF and then start the same discussion and explanations of QFT ❤❤❤❤❤❤
represents the velocity of the position_average of the system with time. It's more useful to us as it gives us an idea of how the wavepacket evolves with time.
Consider a particle in a infinite square well potential of with two nanometer calculate the expectation value of particle's position in the ground state.
Great Work , this is very well done. Is it possible to take some real time use of this? Like how somebody uses this to find average postion and use that average position for a real application.
My favorite example is a spectrum analyzer for audio. The longer you capture, the better you can pinpoint low-frequency content. If you want to catch really slow frequencies, you have to wait and collect more samples. This means there's a tradeoff-you're either focusing on when something happened (time) or what frequencies were present. It’s kind of like position and momentum being conjugate variables. The more you know about one, the less you know about the other. When I first realized that measurement in this context *requires* an integral (over time), it finally clicked for me.
Instead of doing derivations which are already there in any standard textbook, i think you can better solve problems (for example, problems from JJ Sakrai). Also i didn't see Linear Vector Spaces in the playlist.
It's because this is a beginner level quantum mechanics no need for introducing vector spaces if we go by introducing vector spaces students need to know some prior functional analysis which isn't necessary for introductory quantum mechanics
"The wavefunction contains information but does not have any physical significance".--Hmmm. I see the point you are making there, but not convinced it is true. This is kind of like saying the equation of motion in classical mechanics does not have any physical significance since classical mechanics is a special case of the more general quantum approach.
By that I mean, The wavefunction is not a physical quantity, but contains information about the average of various physical quantities like position, momentum etc (and later we will see, it also contains information about eigenvalues etc). In Classical mechanics however, the equations of motion reveal to us - solutions which are physical quantities, like position, momentum, energy etc
Bhai simple English use krna seekho , if u can teach quantum physics to a 10 year old , then only u tend to become a good teacher or else its useless…… And please dont get offended by the message its just an advice for me…… When I try to learn something from your videos its like im learning a rocket science 🧪

Try Sanju physics also if you can speak Hindi.

Man these lectures are work of art
I can't imagine how much work goes in creating these lectures they are some of the best lectures on this subject out there thank you so much 😍😍😍😍😍
Thank you so much :)
So much work and so effortless, lot to learn from here
I really wish We had Teachers like you sir.... You really made this difficult topic extremely easy to understand..... Thank You so Much sir... Amar pronam neben 🙏🙏🙏
hands down the best channel for quantum mechanics
Your limitless passion and preciseness is infectious man!!
High clarity.. congrats Prof.
Amazing ... The best series on QM I have ever seen
truly the definition of "For the love of physics"
missing Bra-Ket notation and properties of inner and outer products
I hear you but I am also finding it refreshing, his command of integration is comforting. I look forward to seeing how he handles vector fields too!
please don't stop making these videos pleaseeeeeeeee just keep on going till the starting QTF and then start the same discussion and explanations of QFT ❤❤❤❤❤❤
@@Akash_Saxena_2013 thank you for your great suggestion 💖
Love this lecture series❤
Very nice work sir 😊😊😊
You are a great teacher,explainer sir❤
Thanks a lot sir Physics is ❤
I really enjoyed your lecture and you have helped me in quantum mechanics, kindly I'm asking for the book you are using.
He is a great teacher of physics
Thanks a lot for this lecture series
In 28:15, does X depend on time? or the value of full derivative of this product, where term with dx/dt is equal 0 for some reason
x as a variable is independent of t
being patient for expectation of understanding Quantum physic
gives an idea of a particle of what's expectation values
extremely useful thank you
I don't know why your youtube channel hasn't millions subscriber
Excellent command in quany mechanics
Why is =d/dt , but not ? Are they same?
represents the velocity of the position_average of the system with time. It's more useful to us as it gives us an idea of how the wavepacket evolves with time.
you help me alot
Consider a particle in a infinite square well potential of with two nanometer calculate the expectation value of particle's position in the ground state.

Thank you very much

Sir please suggest me a good book for atomic and molecular physics
@@Akash_Saxena_2013thanks
Sir, I await your playlist on General Relativity.
he already posted i think in his channel
Thanks sir
hello sir, please upload the notes for the previous and this video. thank you
Hello sir, if possible can you upload pending lectures
I've my exam on 18th in IIT indore & I'm getting good with your series..❤
How was ur exam buddy
@@AshishJoshi-tj3qs good

Thank you very much for your response and explanation....@@FortheLoveofPhysics
Woww
❤❤
In general I love you videos and watch everyone of them. At 38:50 dx dx is bad notation, sorry.
You mean to say, there should be a parentheses?
@@FortheLoveofPhysics better notation would be if one of the x’s have a prime on it.
Hmm. I understand what you are saying. Btw are u a mathematician by any chance?
@@FortheLoveofPhysics I have a masters in math and I am working on a PhD in physics. ☺️
Awesome:)
