I have never been delighted this much by a lecture for my whole entire life. And in my humble opinion I believe the reason for him to be so influential is about his own philosophy on the matter. I believe his mentality quite literally yells at us saying "I came to teach physics of the nature surrounding us" rather than "I came to teach classical mechanics which is a sub part of the field called physics which also happened to be describing the nature surrounding us" . The way he introduces the course to the student felt as if he was presenting his aphorisms to the audience. Hence I would like to deeply thank to the people who contributed this digital platform to share this masterpiece.
Prof. I must say you are by far the best physicist in youtube lectures. Unparalelled, not even prof. Susskind! India should be very proud of you. Thanks for great lectures! Absolutely the best. 🙏🌹
Yeah. Undoubtedly, he is a legend ! The Indian Institutes of Technology (IITs) are the best here in India and they have many gems like Prof Balakrishnan, who used to teach at IIT Madras. Another such legend is Prof. Suman Chakraborty, from the Department of Mechanical Engineering at IIT Kharagpur. His lectures on Fluid Mechanics and Computational Fluid Dynamics are spectacular ! I mean there are countless more ...

I followed these video lectures during my undergraduate career, the ones in CM and QM and coming back to them I have to say; Professor Balakrishnan is by any measure the best lecturer I have ever seen. The course of the lectures fit in perfectly with a reading of Goldstein/Taylor and the QM lectures especially fit in well with a reading of Sakurai. I'd love to see him add to his lecture series with a course in classical electrodynamics and relativistic quantum mechanics.
If i were teaching an introductory physics course in college, i would assign this video as a first lesson and then use class time to discuss it. This is wonderful! Physics education around the world is improved by having this publicly available. Thank you Prof. Balakrishnan.
After listening to the lecture, I can say with certainty that only those who are clear with the subject can teach it in the most simple form. Sheer joy!
I am really glad I was born in this era where you can gain knowledge about absolutely anything and getting the best of lectures to learn from. I was fascinated by physics since childhood and never found a way beyond the books as I fairly understood them. Now, its far better to understand.
I'm a freshman studying mechanical engineering, and I just love physics, I'm self learning this and I plan on moving to quantum mechanics later on, this is really helpful, thank you!
Pure philosophy in Classical Physics is commented here. Sir, you have led me to think into and out of our perceptions. I pay my due respects to this great Professor.
the comments about wave particle duality and imaginary numbers - I wish someone illuminated it to this level of clarity to me at Uni. The fact that all of these are abstractions based on a shared set of semantics is so beautifully described by Prof. Balakrishnan. You are an inspiration, Sir!
I remember watching Balakrishnan's videos before college, which definitely kindled a passion for physics and math deep inside me. Then I also started reading advanced books, which were not even part of the course syllabus, for example the famous series of books published by Lifshitz and Landau. Among other things, I solved many of the classical physics exercises in the first book "Mechanics" step by step in an online course on Udemy (called: "Classical Physics: how to solve advanced mechanics problems"), which deals with the mathematics and physics of rigid bodies, non-inertial systems, and much more. This is to say that videos like these can be very helpful in inspiring youngsters to appreciate physics.
I like the opening, its like a call to learn & I'm not Indian. This is a brilliant professor, its a pleasure to listen to him. I listen to his lectures and read my own physics text.
What a fantastic and inspiring speaker and explainer of complex ideas. I would recommend this series of lectures to people with scientific and non scientific backgrounds alike.
"these are all abstractions... and we'll try to put them into *correspondence* with physical objects" Epic explanation on the use of imaginary numbers. Numbers are simply (mathematical) objects for which certain properties hold. The fact that certain classes are more apparent in our classical lives (e.g. integers - counting number of apples) does not mean one should think of other classes as less "real".
he is the best teacher i ever had. i got an opportunity to attend 2 courses of him in dept of phy iitm. 1)statistical thermodynamics 2)contemperrory physics /We call him with respect "balki" . in our department Balki is a word like boss.. One of the best teacher in the world
So this is like the best lecture I have ever seen , Professor Balakrishnan is truly an enigma and is very passionate about physics as which can also be seen from his lectures.
the whole discussion on electrons as a wave/particle was probably best described by sir here.. he explained it so beautifully and simply.. very few lecturers in the world have the gift of simplifying without resorting to reductionism.. the classification of electrons were simply "a failure of ordinary language".. brilliant
Sir you are amazing.i have never seen such a kind hearted and talented teacher in youtube platform.I have learned many concept of quantum mechanics and classical mechanics.आपके चरणों में नमन(bow at your feet).Thank you so much sir🙏🏻 sir.
I was not expecting to hear such a wonderful lecture. The Professor exposes so well the mater and without compromising a deep insight to the matter Thank you a lot for posting these lectures!!!
Thank you for your lessons. You are gifted in communicating the very essence of the understanding of the meaning of terminology the and application of formulas, and for that; I am grateful. I hope to meet you someday.
I don't understand why nptelhrd won't upload more videos of Dr. Balakrishnan classes. I'd kill to see his full curse on E&M or on Field Theory, which he hints about in many occasions during these lectures.
Weight W = mg W = weight, N m = mass, kg g = gravitational acceleration, m/s2 or N/kg Force F = ma F = force, N m = mass, kg a = acceleration, m/s2 Moment of a force about a point Object in equilibrium with parallel forces acting on it Work done W = Fd W = work done, J F = force, N d = displacement, m Kinetic energy K.E.= 1/2 mv2 K = kinetic energy, J m = mass, kg v = velocity, m/s Potential energy P.E. = mgh Ep = potential energy, J
I am glad i stumbled upon this lecture. Great voice, accent, articulation, not to mention the depth of teaching. I didn't understand the part at 22.10 where he says "When u apply a force on a body, u change it's velocity, not position"
The change of position (1) is a result of a change in velocity (2), which in turn is a result of applying force (3). He is saying that it would be incorrect to say that 3 leads directly to 1, which is how most people would view it. Most people would think that 2 and 3 are the same thing, which they are obviously not.
You're right Johnson. He says that too. But the point he is making in the video is that people thought force changes position only and not its velocity which was thought to be constant. But in reality it's the velocity that changes and position as a consequence
This video is amazing for me I ever experienced so I learned alot from this video so thank you for this great video you introduce so thank you and thank you
He does this thing at every completed point where he makes a high sounding noise. Kind of like Mr. Mackey from South Park when he says, "Drugs are bad, MKay". It's that Mkay part that his high sound equates to.
There's something really profound about 21:54 "this is why you THINK you understand Newtonian Physics... there's nothing intuitive about it". That's something I've never thought about
Father of marthematical quantum mechanics -Paul Dirac was a Bristal University educated electrical engineer who end of doing research in physics since there were no work for engineers at that time. No doubt late nobel prize winner went to be the Einstein of physics in UK and a role model for Richard Feyman originator of Feyman diagram and QED.Again RF was good in mathematics but was advised to do accounting but he end up doing engineering which he didnot like and did physics at MIT.
@vjpillay What you think about this?; A photon travels on a straight line but the nature of the universe rotates (like circles) so when the particle hits a mass, at different time and space, we see a wave like effect becaise the rotations of the universe do not effect photons.. It is just a personal hypothesis and the chances of being right are small. But the point is that there must be a logic, comprehendible way to explain this..
