    I studied maths at Cambridge; I've watched a bunch of online lectures from Stanford and MIT on related subjects. This lecture stands out as a fantastic learning experience. There may be better researchers out there, but this guy is the most impressive and engaging teacher I've ever seen.

      @Ultimate Game I study physics at IITM, and I've attended a few lectures by prof. Balkrishnan.
      But you're wrong, professors at IIT aren't all good.
      There are some very good teachers but many are just bad.
      I've been teaching myself mostly for past 4 years. In any semester I usually have 2/6 good professors. 2 okayish professors and 2 extremely bad professors

    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 :)

      Ram Krishna I'm not at all surprised at English fluency in India. I worked in Medicine in England and Indian graduates in my field (psychiatry) had an excellent grasp of English - which has for years been the language of their education. Ironically immigration rules meant that while EU doctors could come freely to the UK, sometimes with distinctly less good English, while fluent Indian/Pakistani staff found coming to the UK much more difficult.

      Actually best of them come to the US.Unlike 'straya , people - applying
      for the US uni - need to take Graduate Record Exam ( mandatory for STEM
      graduate programs) and TOEFL (English exam , in which speaking skills
      are tested too). Admission in coveted universities such depends upon the
      scores in the aforementioned exams.Very recently - Singapore ,
      Australia , and New Zealand also taking these scores seriously.We can say : crème de la crème from all of these Asian countries ( including China , Iran ,Taiwan, etc.) are moving to the US (more than any other country.Sociologists have term to explain this phenomenon .It's called as brain drain.

      @Wiz not really. Religion has been one of the major factors the human species survived. The contribution of the ability to come up with imaginary stories and believe them to our evolutionary success is dominantly major and important. Not only beneficial to the survival, but the circuits we developed in our brains to help us do that are also the same things also help us come up with creative solutions.

    • @Sandy-rv9tv
      @Sandy-rv9tv 2 роки тому

      @Wiz I used to think likewise. However as I dug deeper into my religion (Hinduism) and for instance studied meditation, I observed it has deep parallels to the Heisenberg's Uncertainty Principle which is discussed right here in this Lecture. There are two ways one can meditate, either using concentration and when one does that we are focused on the present losing sense of direction of thought. This is like determing Position of the particle and obviously we cannot determine momentum then. You try to determine both you cant meditate then. In the other method of meditation, where we use awareness we are focusing on direction of thought (momentum) and losing control of any particular meaning or content of thought (position). So there's a direct one to one correspondence with the Uncertainty Principle.

    I studied under Balki for 2 years. He was just amazing, though I failed in his exam and later passed successfully though... Very amazing. A real Guru, A Real Master...
    ThisGuru's style made me to my business far better and sharper... Thanks to this Great Guru. We also had another Guru, Dr. Swami, Balki's great friend. One of the greatest ever teacher!!

    For students who have to pass an exam, Prof. Balakrishnan's lectures are top-class. But if you are just a curious person in knowing about quantum mechanics, or if I am interested in attracting more and more ordinary people to get interested in this subject, many, many much-better-produced attention-getting and interesting videos are available on UA-cam now. You will be missing out on a great lifetime experience if you don't look at some of them. You should also look at videos on Special Relativity. Then your familiarity with modern physics is complete!

    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.

    It is amazing how good his English is. I wish my students can someday speak like him.
    I don't think they will be as good a physicist as this prof, but at least if they are good speakers, I'll be more than happy.
    I also like those bright young students some are asking very smart questions. So here is a question for all of you - What is really an electric charge? You probably know that "What is mass?" has sort of been answered after Higg's Bosons were proven to exist.

    • @Absol-ute
      @Absol-ute 9 років тому +2

      Rocky Sinai - String theory gives a very geometrically fundamental meaning of electric charge . It is the ratio of planck length to the string length (various vibration modes(excitation states of the string) have various resonating lengths), And electric charge is the ratio of planck length to this length . AND, mass is similarly defined as, the difference in the vibrational energy of the string and the rotation energy(spin energy) of the string .

      "And electric charge is the ratio of Planck length to this length"
      Pretty good answer. What is the unit ?
      Hope string theory gets some proof, some more interest among the researchers and wider acceptance.
      Best wishes.

    I had gone through the first 29 lectures in this series, and those entire section was exemplary. Am really feeling jealous to the students in the class, i know they are talented, because they have got a professor like him. I didn't get the reason why one of our union minister,he is also from iit, had made some slanderous remark about this exceptional persons. Our minister had to spend a little time in front of NPTELvideos before making those kind of egregious remark.

    Damn it! These lectures make the sylabus at my old Uni pale in comnparison. Just another reason to be dissapointed with most of the three years I spent studying there. So much missing from the Physics that I took. Thermodynamics was completely absent, so was (mostly) Hamiltonian mechanics! Wish I had this 5 yrs ago.

      It's not an anime. It's regular animation with a chant from the Krishna Yajurveda Taittiriya Upanishad called Shanti mantra used by students and teacher before the start of a class traditionally in the background.
      And if you really like the chant you can find more on youtube if you look up "Vedic chants". They are over 4000 years old and had minimal change in pronunciation and intonation since then.
