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.
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.
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
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
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)
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.
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.
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.
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
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!
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!!!!
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)
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
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.
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!
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...❤
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
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.
simply you made the Quantum Easy to understand while Balakrishnan complicates the thing with his knowledge . teacher become teacher by how he/she deliver the knowledge to student not by how much knowledge teacher have . her approach is steady while balakrishnan approach is rigorous.
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.
I only watched a little of the vid. The presentation was very clear and the presenter very articulate and easy to understand. I didn't got to any difficult 'bit' lol What I don't understand is why you choose to write everything down. This IMO unnecessarily slowed down the progress of video.
photoelectric effect can be considered as evidence for particle nature of 'light' and NOT as evidence for particle nature of 'electron'. I think Einstein only explained the photoelectric effect and did not discover it.
Very good video! This is an invitation to see an artist theory on the physics of light & time Based on just two postulates 1 The quantum wave particle function Ψ or probability function represents the forward passage of time itself with the future unfolding photon by photon. 2 Is that quantum uncertainty ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual
Content is good but presentation by writing on the board is random and floating thoughts rather than sequential. Examples are avoided in such a mathematical topic. One can use many publications to plan the presentation such as the book by Griffith - present through “worked out examples”.

Yes you are right yar
Bro , pls understand me quantum mechanics
Brilliant
@@smrutiranjanmohapatra5487 😅 it's self understanding not understanding from others..
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.
From all the videos of Quantum mechanics she is the best professor I can find. Thanks professor for your time making this videos
Absolutely....she is the best...lots of love and respect from hunza Pakistan
Try quantum mechanics by prof. Balakrishnan
There is For The Love of Physics too. Very good teacher.
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
The lectures on QM by Prof. Bala are really wonderful, very lucid and insightful.

The most precise definition and introduction to Quantum Mechanics!

No other video on introduction to quantum can be better than this..You made things way easier than they seem to be!!
See 🙈 quantum mechanics from prof. Balakrishna of iitm . They are in UA-cam nptel .

I prefer to attend your lectures instead of college lectures. Very nice teaching which i can understand easily. Thanks Ma'm...
so neatly delivered. I don't have a good physics background though i grasped everything she said.
Folks why is it that for the all these years not a single Noble prize has been won by an IITian. It has always amazed me.
they r not researchers
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
Really ur way of teaching is so interesting... I'm going to see daily one lecture and learn...
Thanks...
These lectures are great, shes a great lecturer, clear and precise
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.
This is brilliant stuff; One of the best out there.
This is not just physics but high level of nature philosophy
Excellent introduction. So glad these videos sre available and accessible to the rest of the world.

👏..excellent presentation of Quantum Mechanics..✌️
I am an engineering student this is fun to watch
Who is watching this in 2024👇
please do not litter
mam a great explanation and diffrence between classical mechanics and quantum mech.
thank you mam for your contribution and helpful series of lecture
I wish subjects as quantum mechanics be respected in every way
U r doing a great help for students. It is very understandable.
This is very good, Prof. Bala.
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

The world's best Queen teacher thanks
Very intellectual method of teaching
This video has made me want to learn quantum physics
Wow! This is extremely brilliant, thanks professor.
"Measurement errors is an inherent feature of Quantum Mechanics"

Best teacher good explanation
Love you madam...,I lost fear of quantum mechanics
Awesome video , please upload all the courses
Great, really great! Thank you Prof. Bala.
Your way of teaching is really #AllurinG
ThankS MaM .....
YoU arE reallY greaT
Such a wonderful lecture, please also upload classical mechanics lectures by Laxmi Mam.🙏🏻
Thank you so much Ma'am. Stay blessed.
Which books she's using for reference?
Kindly anyone mention the book 📖 followed the Mam in the lecture
Mam can u do a vedio about set exam syllabus nd explain the topics
Excellent talk!
very clear explanation....
Thanks for your effort to make understand such difficult concept s
very nice .. sir upload new video from different iit
simply you made the Quantum Easy to understand while Balakrishnan complicates the thing with his knowledge . teacher become teacher by how he/she deliver the knowledge to student not by how much knowledge teacher have . her approach is steady while balakrishnan approach is rigorous.
Rehan Ahmed not true professor balakrishnan sir explains it inn a really easy way
Yes
Rehan Ahmed It’s true sometime
Bro.. Balakrishnan is genius
Balakrishnan is very knowledgeable professor may not be a good teacher. Both are different things.
Oho.what a wonderful lecture 👍
Hermtian matrix linearvector space..wow!! Thank you so much ma'am..
Very good explanation madem 🙏🙏🙏🙏explaining super
To explain quantum mechanics, start with the basics of classical Newtonian mechanics first and then explain its limitations
Wow....professor you the just awesome...god bless you.
Very interesting topic in physics
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.
Can BSC student use this course
Mam you are great. You have make quantum mechanics simple. Thanks for your videos.
Very helpful and hats of to you prof.
love and gratitude from Pakistan.
Ye mam sath mn book konsi follow kar rahi?
This is awesome. Many many thanks.
please explain to me why the quantum spin number is expressed as 1/2 and -1/2
Is there any quantum 2 video series?
29:10 can anyone tell me why there will be an infinite eigen value ,in that problem?
Nice video madam. Very good explanation. Which is the best book for Quantum mechanics madam?
Very nice explanation mam thank you
Thanks madam your lecture is awesome...
thank you maam for explaning quantum mechanics in a great way
Thank you very much for this lecture!
R the subsequent lectures of quantum mechanics is available ???
tanushree mahato , yes of course
Available lecture
Yes dear around 40 videos in her qmechanics series
I only watched a little of the vid.
The presentation was very clear and the presenter very articulate and easy to understand.
I didn't got to any difficult 'bit' lol
What I don't understand is why you choose to write everything down.
This IMO unnecessarily slowed down the progress of video.
it gives the listener time to reflect and think about what has just been said :O) I like it and they all do this
where i can find quantum mechanics II lectures?
it's helpful to students
Is it Bohr and Jordan or born and Jordan
photoelectric effect can be considered as evidence for particle nature of 'light' and NOT as evidence for particle nature of 'electron'. I think Einstein only explained the photoelectric effect and did not discover it.
+Gyaneshwaran G
Hertz discovered it in 1887.
Really really amazing lecture
Thank you very much.
Keep the GOOD WORK>>
Good lecture, thank u mam
Plz suggest some books to cover this course
This course is for undergrad physics students right??? Cause I couldn't find any other standard material on QM for undergrads...
good job mam......thank u so much
Superb lecture
Nice explanation 👌
This video video is for bsc or msc?
Great ma'am !!
U r genius ma'am
madam which book we should follow?
Is there any lecture notes ?
Very good video!
