Being a Physics student, this topic is very important and widely used in our syllabus...I had many doubts in this topic...but now, I finally got the very basic concepts from this lecture...Thank you Sir 😊

[@ayushdhingra855]

Same here

Same....and thank you sir

[@vivekasarkar5379]

I'm a Physics Student... And It's a Very Important Thing In Quantum Mechanics and As Well As Mathematical Physics (Linear Vector Space)... It Is Necessary For calculations! From Some Days I Was Struggling With This Concept... But Now It's Totally Clear To Me...!!! U've completely Removed All My Doubts in a Very Easy nd Simple Way... Thank You So Much Vaiya...!!! Just Carry On Like This...!!! 😇❤️✨

at 10:24 there is ket-bra, is it the same as bra-ket?

what does this mean: (-1/2 del squared minus 1/r)|2s》?

[@shovandeshi7006]

i like the technique of teaching sir. thank you.

sir we will be greatly benefited if you make videos like this on all chapters of Quantum mechanics.. Because your way of explanation is very much good that is very helpful for me.

Thank you sir, but I have some confusion , you are putting the two different wave function for orthogonal condition in the numerals (type)of the topic Algebra in Dirac notation ,but in orthogonal condition we have same wave function and that's value is zero....???

Sir please make s series of newly added topic to gate..

Alright Kanika, will try for that

Can you explain the answer of 2019 gate qsn from dirac notation

[@juzeralirangwala3539]

Forget teaching we haven't heard about it anywhere......I doubt whether it was part of syllabus before and it has any sort of utility for a chemist or biochemist.....

[@AllBoutChemistry]

That's a problem with our education system, they generally ignore some complicated topics at learning stage and directly include that in syllabus of Entrance exams.

[@juzeralirangwala3539]

@@AllBoutChemistry Agreed.......I cleared MP SET and then MP PSC for Asst prof in 2018......now while teaching in college I realised that whatever we studied for NET/SET has very little relevance with our UG/PG syllabus......U guys are doing great job.....l recommend your channel to my students who are aspiring to become lecturer and want to clear National level exams...... keep up the good work.....stay safe stay healthy

You both can explain each other, the one which Shreya got that Chetan didn't get and vice-versa. 😁

There might be just a calculation mistake... Be very careful while doing multiplication of two terms of ket and bra vectors.
