Dear Prof. Balakrishnan,
I would like to thank your for your youtube courses in CP
and QPhysics!
They contain a lot of what I wanted to know about physics
and did not dare to ask :-)
I am an experienced Italian electronic engineer who had the
chance to work at CERN long time ago, then microelectronics
designer and now I moved to commercial side of the
optoelectronic industry, but physics and life science are
still my passion. I love your balance between rigour
approach w/ always with in mind the overall picture (e.g. :br>your lectures on dynamical systems) and without never
reducing it to specialism.
Are you planning to post also lectures on quantum field
theory? And I think it would be great if you could use your
knowledge and style to lectures on biology, system biology
or complex system etc.. These might not be your tradition
area of expertise but I am sure you will bring original
ideas in these branches of modern science.
Kind Regards,,

Can not turn off those stupid captions. The captions are
covering up the lecture. Either get rid of captions or just
remove entire lecture.

Beautiful lecture, I wish to study under the sound guidance
of such a knowledgeable teacher. Hats off to you sir. I
finally i get what a state vector & Linear vector space
is....
I would like to know that what are the texts prescribed for
this courses.

This is an exquisite treatment of linear algebra and quantum
mechanics. Prof Balkrishnan is best

it is very help ful to improve the concepts and applications
of quantum mechanics by listening this lecture to me

This is a first-rate treatment of quantum mechanics.
Strongly recommended to any student of the subject.
