    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.

    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.

    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.

  • @aayusharya6899
    @aayusharya6899 4 роки тому +2

    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.

    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!

    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)

    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.

    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!

      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.

    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.

    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”.
