plz, suggest good books for quantum mechanics

Could this ‘uncertainty’ be explained in a logical intuitive way if we had an interactive emergent process unfolding photon by photon? This idea is based on: (E=ˠM˳C²)∞ with energy ∆E equals mass ∆M linked to the Lorentz contraction ˠ of space and time. The Lorentz contraction ˠ represents the time dilation of Einstein’s Theory of Relativity. We have energy ∆E slowing the rate that time ∆t flows as a universal process of energy exchange or continuous creation. Mass will increase relative to this process with gravity being a secondary force to the electromagnetic force. The c² represents the speed of light c radiating out in a sphere 4π of EMR from its radius forming a square c² of probability. We have to square the probability of the wave-function Ψ because the area of the sphere is equal to the square of the radius of the sphere multiplied by 4π. This simple geometrical process forms the probability and uncertainty of everyday life and at the smallest scale of the process is represented mathematically by Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π. In such a theory we have an emergent future unfolding photon by photon with the movement of charge and flow of EM fields. This gives us a geometrical reason for positive and negative charge with a concaved inner surface for negative charge and a convexed outer surface for positive charge. The brackets in the equation (E=ˠM˳C²)∞ represent a dynamic boundary condition of an individual reference frame with an Arrow of Time or time line for each frame of reference. The infinity ∞ symbol represents an infinite number of dynamic interactive reference frames that are continuously coming in and out of existence. Thanks for sharing your info!!!

What an excellent introduction Prof Balakrishnan. Viewers, see it at x1.25.

Thank me later.

Is this the btech engineering physics class????

nice. thanks sir

I cannot help inwardly laughing and shaking my head at the sheer brilliance of the man,

Nice

Damn. Wish I could crack JEE Advanced to learn from this amazing man.

The conferences are great and I revisit them frequently and recommend them as well. It would be nice to add descriptions to the videos so it's easier to find a specific subject.

Sir u r awesome, pls give the each lecture name

At start he says math in quantum is simpler than classical mech.. But if u are gud at math physics is Just like drinking water…an struggling in masters because I am not fud at math

Excellent Sir.

Thank you very much for such a great lecture series.

Realllyy informtive lecture

Its incredible he never does one simple excercise. Thats not a healthy way to learn physics but theology. He is just adding facts and facts but not teaching to develop the physical reasoning.

9:02 That's me!! Not understanding a word he's saying but giving it a shot anyway. lol.

sir please explain how fuzzy logic techniques related to fuzzy physics?

Can they provide in hindi???

This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. Within such a process the wave particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with forming the possible into the actual! The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the wavelength of the electromagnetic spectrum. As part of a universal process of energy exchange that forms the ever changing world of our everyday life the ‘past’ has gone forever. At the smallest scale of this process the ‘past’ is represented by anti-matter annihilation with the symmetry between matter and anti-matter representing the symmetry between the future and the past as the future unfolds photon by photon. In such a theory the mathematics of quantum mechanics represents the physics of ‘time’ with the classical physics of Newton representing processes over a period of time, as in Newton’s differential equations. In my videos I explain how this process is relative to temperature and the phase changes of matter.

i feel proud i am studying vedas

Great lecture..

Sir hindi me padao

great sir

Prof. of ((so on)) hehe

It is just joke.

sir plz tell me any free youtube channel for studying bsc level

chemistry ,botany &zoology

Thank u so much sir for all the lectures.U are no doubtely one of the best ….A huge thank u to NPTEL

U r the best teacher in my life who give me such a depth which I really want

Prof. V.Balakrishnan Retired from IIT Madras on 2015. I joined IIT Madras during 2016. After watching his series of lectures I feel I was not lucky enough to be a student during his period. Hats off to Prof. V. Balki.

An fantastic lecture

Once I thought that india doesn't have quality faculties but this lecture breaks my myth

What an lecture sir no hocus pocus nothing but only intellect an pure intellect

What level is this?

Superb lecture.

SO GOOD

if you loose concentration for 2 sec, you won't be able to catch the 3rd one.

Thank you sir

I wish i could go back in time and studied hard for IIT JEE so that i could learn from this EXCELLENT PERSON

A smooth and clear lecture.

Sublime sir. Remarkable method.

Excellent

what class is it ? Bsc or Msc ?

A doubt about uncertainty principle: Suppose I have a particle in 3D with known total momentum say p. I can find say position say x and momentum p_y and p_z with arbitrary precision simultaneously. Now I can find P_x by using P, P_y and P_z so I could find P_x and X simultaneously with arbitary precision. Where is the flaw in this argument?

I am glad that my doubt about uncertainty principle got cleared ,I though it was experimental

nice moment for me to study in online mode…tnku sir….

Best video?

respect for you sir

we need more information like this being pushed into the world it only takes one person to solve any question but it take all thinking creatures to find that one person

Is not it really my dream to meet this legend at least once in my life?? A great salute ,He is my God

Very nice explanation I have ever seen

I'm listening this great lecture in 2019

Plz reply anyone that in iits under which course quantum physics is teached.

Or it is compulsory in every course plzz reply anyone.

Are there lecture notes for this course?

One of my favourite topic

Great prof……

Sir u r great

I want to give small question to you sir- Graham bell recharged his first phone without any SIM card and even though recharges are also not available at that time???

?????

https://youtu.be/Z9SfhFo5Fzc

Watch this video also and thank me later

One of the best on qm intro

I am not a bright student (for an analogy to be made I am a diesel engine not gasoline engine, my flash point is high) my flash point is high so that I would not start easily if I am sitting in that class room at that moment. But I am grateful for all the mankind who made it possible for me to watch it on YouTube so I can stop, start again, repeat until I understand! I would from now on blame myself rather than anyone to stay ignorant. Getting enlightened! Not giving credits for just this video but everything out there we can learn from and for people who made it possible so far! A true thanks from me!

I'm glad I watched this video. I could say more but you understand

this is actually a good teacher

& greatest lecture of all the time in India

such a professional

Its a great lecture…

❤❤❤❤❤

I haven't find out the Quantum Mechanics lecture like this…..in first it seems to be complicated to understand but when u have some basic knowledge about that subject then it seems like a fabulous lecture….

Very educating environment in classroom….the Answer by Prof. Is outstandingly Awesome….

I was one of the extremely fortunate students (IITM 2005-2009 BTech batch) where I had opportunity to attend this course, classical physics and Math Physics under Prof. Balki. I studied at several countries later including Europe and US. By far he has been the best teacher I have ever had in my entire life. I remember I always used to look at my watch to see how long more the class will last for any other lecture but with Balki i was like "the class is already over.. i wish he could lecture for some more time " .. I was never interested to attend courses or lectures but Balki taught Physics as if it is some engaging Thriller movie! You can find me in these lectures as well 🙂

The quality of these lecture series are very good. I wonder how /why similar lectures of Susskind made much later are almost unclear and inaudible.

sir, your lecture is very very nice

Without mathematics there couldn't have been any physics of quantum mechanics. Again, it is mathematics that made discovery of QFT and self-correcting, se;l-simulating, infinite dimensional, quantum computing function. The universe is a QC (Maldacena) . Life is a QC function. (SMNH).

Our five senses, our brain and all our cells act in unison to re[air/regenerate 50-70 billion damaged cells daily. QC provides the clue how the parameter space is fine tuned and how a single probability wave function govern everything in the universe, eliminating randomness/chance so we can survive in a violent and dangerous universe and evolve.

Can someone explain me about the example sir gave about Pauli exclusion principle two solids can't penetrate

49:36 Planck time is 10^-42 s. Now Google "what is the answer to life the universe and everything"….

Tq sir

It would be nice if clarity is increased

Sir please please Hindi Mai vedio banayeye please sir

?

Evolution Revolution DisEvolution

Can anyone who completed listening to all 30 lectures comment down the contents or topics discussed in each of the videos? It would be very helpful.

We Don't Know Is It's Interpretation to Complete SatisfactionIt is an intrinsic property….And

that's the way it is…..Ohhh…. Professor….!!!! Your Lecture Seems Me Much Spiritual…..

ThAnk You…….

Classical Mechanics Is An Approximation Of Quantum Mechanics????

It Looks Like We've Not Succeeded…

Physics Is Not Mathematics☺️??

We Must Know & We Will Know…

nyc

A GREAT TEACHER!!!! VERY WELL PRESENTED!!!! THANK YOU!!!!

Say.. my Name…

Where can i find these lecture notes?

very good lecture and fluent communication

The greatest video on YouTube period .

Many students in the comment section are here to judge his teaching rather than learning from his intuitions and explanation.

203 dislikes !!! These people want mandir instead of knowledge !!! ?

The secret of quantum mechanics is "It's really work in real life situation"

@37:27 remove language for understanding quantum mechanics, because mechanics of language is limited but quantum mechanics works for multiverse.

"That's is why mathematics is universal language"

Plz improve camera quality

Its great ..its 4 am and this is not even in my course still studying for knowledge.

I did my quantum chemistry course under another brilliant professor, Prof Mangala Sunder during my undergrad days at IIT Madras years back. Before leaving the campus I made sure, I attend some of Prof Balki's lectures/talks (none part of my coursework). His intuition, depth of subject , clarity in speech, ability to infuse mathematics and occasional humor, keeps students engaged for hours. A lifetime experience for students and a perfect model lecture for future lecturers/teachers on how to teach.

Sir I am in 10th so tell me how to career in quantam physic ?????

Glued to the lecture. Prof is a like a beautifully scripted enjoyable book

where is previous semester lecture

A legend from IIT MADRAS.
