[@sman8586]

I'm a graduate student of physics,and I can say this professor explains quantum concepts in best method,we should appreciate her,because she spend her time and energy, experience and knowledge to record this great video,thank you dear professor.

[@brahmanandapradhan1470]

S Man Yes you are right yar

[@smrutiranjanmohapatra5487]

Bro , pls understand me quantum mechanics

[@SHIROShinchanDOG]

Brilliant

[@honestyisbestpolicy414]

@@smrutiranjanmohapatra5487 😅 it's self understanding not understanding from others..

[@GibranKhalil1969]

From all the videos of Quantum mechanics she is the best professor I can find. Thanks professor for your time making this videos

[@learnphysicswithazizahmed4344]

Absolutely....she is the best...lots of love and respect from hunza Pakistan

[@vivekvaghela2274]

Try quantum mechanics by prof. Balakrishnan

[@doutormanhattan5680]

There is For The Love of Physics too. Very good teacher.

[@Gismho]

This lady is very, very good at explanations. Also, her handwriting is totally legible, unlike many "professors" on the net. This is a very good series of lectures. Thank you Professor S. L. Bala.

[@oldcar8592]

This lecture is great. I've been watching lectures at MIT, Yale, NPTEL and one thing they all have in common is that the instructor writes the topics he or she is talking about on a blackboard which helps me to remember what I'm trying to learn. Also, if the instructor has drawn several diagrams it's more comfortable seeing the hand movements vs an animated instruction where there's no indication where the cursor will move among diagrams which sometime causes me to rewind the video. And great job by the person recording the video keeping enough text in view.

Most of th eindian teachers are very good at least i had been lucky; i came to apris in 1966 after my m.sca dn one year traiig school and 5y at tifr; hardly tw o three profesors i paris could matchmy teachers in christina cllege chennai and hbhabaha training school; now listen to an indian prof in yale Prof shanker super good;check u tube

[@sufyanramzan6773]

Hey guys! let me share my experience. couple of months back i watch lec # 31 of this course to solve my class assignment, while doing so i decided to took this course from the begging. And today i started and found it really helpful . I am quite hopeful this course goona polish my quantum knowledge :D :) A Great effort and bundle of thanks for sharing it openly (y)

The lectures on QM by Prof. Bala are really wonderful, very lucid and insightful.

[@adarshpandey4259]

Goosebumps , i hope that all schools and colleges should get such professors and teachers , she directly link the whole general life with quantum and mathematical life just listen her carefully

[@piyushchakravarti333]

I am a teacher of senior secondary school.whenever I go through your classes i feel all the content lucidly and distinguishingly represented only the learners need attention, prior studyand analytical bent of mind.keep it up.

[@hariprasadvp4866]

The most precise definition and introduction to Quantum Mechanics!

[@JalalUddin-nn3yb]

Really a great introduction of QM physics, the way of flow of information is amazing! As you got a good grip on various mathematical and theoretical explanation of different eras on QM by different pioneers and well explain the QM applications.... appreciated teacher!!!!

[@benbrill3617]

What can I add to what has already been said, I’ve probably watched 20 introduction lectures to QM, this is by far my favorite, the one that taught me more than any other. It’s interesting to realize what a difference the right lecturer can make, it’s like day and night, I suppose that’s true for most subjects.

[@ManjinderSinghHanjra]

so neatly delivered. I don't have a good physics background though i grasped everything she said.

[@hamidsultan9156]

Excellent lecturer by the very learned Professor. I am a software professional with a strong interest in Physics. Her style is so clear and simple that even I could understand much of the material presented

[@aayusharya6899]

I figured out by looking at her webpage that she very closely collaborates with Prof. V. Balakrishnan in her research. It isn't directly apparent whether her teaching skills which are at par with Balaki's were a product of this collaboration or existed independently. Excellent lecturer.

[@Anand_Agrawal]

This is brilliant stuff; One of the best out there.

[@PrashantSingh-py5in]

Really ur way of teaching is so interesting... I'm going to see daily one lecture and learn... Thanks...

[@hleiqawi]

Great, really great! Thank you Prof. Bala.

[@punditgi]

Excellent introduction. So glad these videos sre available and accessible to the rest of the world.

[@SONAMSHARMA-ht9yy]

No other video on introduction to quantum can be better than this..You made things way easier than they seem to be!!

[@honestyisbestpolicy414]

See 🙈 quantum mechanics from prof. Balakrishna of iitm . They are in KZbin nptel .

[@mazhar7849]

Nptel this initiative is really good, It will surely help the other students who are interested in Science but can't afford to go to any college, This is a great opportunity to learn from such great teachers and such great college iit madras I never dreamd that I can learn from these genius, I very thankful Thank you so much Nptel In this time era you are pro education provider that also free. Salute to all of you

[@guitaringjarmin]

These lectures are great, shes a great lecturer, clear and precise

[@robertowusu4188]

The Professor has spoken. The lecture has ended. You are too good.

[@amolpawar1661]

I prefer to attend your lectures instead of college lectures. Very nice teaching which i can understand easily. Thanks Ma'm...

[@untwerf]

Does any1 else agree that many of these NPTEL lecture series r let down by poor camera work? I mean sometimes the cameraman will zoom in to a tiny section of the board for example and it means that u r unable to see what else the instructor has written! I find it very significantly impacts on the usefulness of these otherwise excellent lectures when the camera work is not up to scratch!

[@snehasimon9833]

U r doing a great help for students. It is very understandable.

[@elamvaluthis7268]

Nice introduction thank you mam.Classical mechanics holds good for particle nature.wave nature holds good for vector complex analysis so it is derived from old mathematics only wave mechanics not discovered by Issac Newton but uses certain rules also uses sine cos functions of differentian and integration.

[@sbnp9357]

What explanation.... very prominent clear nd cut point.... sometimes i feel the language barriers but still looking forward because it knowledgeable... thanku ma'am and u tube...❤

I am an engineering student this is fun to watch

[@AlphaSciAcademy]

Thank you so much Ma'am. Stay blessed.

[@Dyslexic-Artist-Theory-on-Time]

Based on (E=ˠM˳C²)∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. C² is light radiating out in all directions forming a sphere that can be squared to form the future probability. The brackets represent the boundary condition of the ref-frame within infinity!

Excellent talk!

[@Bhooshan_Jape]

Prof Laxmi Bala is a brilliant professor of physics at IIT madras. I remember she supervised our batch’s experiment on hysteresis curve in magnetism In a lab course. Interested fellows should also watch lectures on quantum mechanics by prof v balakrishnan who is a legendary professor from same department (physics , Iit madras)

[@shivangisoni1852]

very clear explanation....

[@shubhampandey8805]

29:10 can anyone tell me why there will be an infinite eigen value ,in that problem?

[@DeepSeeker2809]

This course is for undergrad physics students right??? Cause I couldn't find any other standard material on QM for undergrads...

[@sahebkhan5395]

Kindly anyone mention the book 📖 followed the Mam in the lecture

[@gundappawade410]

it's helpful to students

[@krishnadaskr4656]

I am 100 percent sure the people who appreciate this instructor, has not listened to Prof. K L Sebastian’s lectures at NPTEL on quantum mechanics.....

[@DeepakSah3.0]

perfect for me.......

[@VishalGupta-lw9dk]

Can BSC student use this course

[@miniphysicist1847]

Plz suggest some books to cover this course

[@woritsez]

probably wrong of me to think of particles as vehicles and waves as information conveyed, but i do, in my mind it nullifies any conflict of dual state of being.

[@kamranabdullah6453]

Ye mam sath mn book konsi follow kar rahi?

Nice video madam. Very good explanation. Which is the best book for Quantum mechanics madam?

[@atoz7388]

madam which book we should follow?

[@amulyaratandas6962]

This video video is for bsc or msc?

[@MubarakAli-su4vq]

very nice explain mom

[@asitmaity6695]

madam I am fall in love with u and as well as physics thank u

[@hasanxnv]

In comparison, I found the prof V. Balakrishnan's lectures of Quantum physics, IITM, much more interesting and well explained..that guy is just super intuitive, explaining each mathematical abstraction in terms of plain language

[@101Scale]

he confuses the student and does not clear the point what he really want to say . he give very few examples that no Average student can understand him . she is easy to understand and more approachable than balakrishnan.

[@sasmitasahoo2209]

[@Deshbhaktii]

Very clear👌

[@mumtazhamid]

Wonderful : )

[@nakummohan7972]

i am beginner in quantum mechanics any one can say whether i would start from dr balakrishnan's lactures or these lactures because when show dr balakrishnan's lacture i fill them some difficult so from where i can start to see the lactures......anyone can give me advice :-)

[@abhinandan008]

Both of them pertain to master's course taught in the IIT's..so maybe those lectures won't help much..I will advise you to see Introduction to QM by Griffith and there is a book of undergraduate QM by MC Jain wherein the author has highlighted all the mathematical steps required to solve various basic level problem like the hydrogen atom solution.So,if you want to take my advise,study Griffith for conceptual knowledge and in depth analysis and intuition and MC jain for explicit mathematical steps..

[@abhinandan008]

But I went through the syllabus of this course,it appears to me that except the LVS preliminaries,rest of the course material is of bachelors..so maybe you can go through this lectures..
