      It's utterly foolish, to say the least, to compare the works of Prof. Ashtekar and Prof. Sen, as the latter (like the former) is widely acclaimed in learned circles as an outstanding physicist. So, please refrain from making such comments on the public domain. If you have anything constructive or informative to add beyond what has already been said about Prof. Sen in this video post, I am all attention!! Jai Barat!! 🙏🇮🇳🙏

    A comments of appreciation of a "Giant " and the channel itself . A man of theoretical physics.
    This video is as if a good review on ' STRING THEORY ' as well as a good review of faces whom I have personally observed as an observer since String 2000 conference @ TIFR, Mumbai.
    I am a proud Indian and proud citizen of Bengal. This field is very much exhausted by all our institutions , but not feel proud for physics or science. Quantum computer might use String in next 💯 s of year. As all we know blackholes always breaks and all its informations can be used as back up memories and hardware for future colliders.
    Good luck all my dears .

Im in Allahabad University (Dr. Sen is just a few kilometres away from where i live in HRI. Yet so far away) I read about the Visiting Student Program at HRI. Do you think I should apply?

I hope you are able to make the switch and best wishes for your studies.

      So, I would say that yeah, go for a physics degree if you want to become a physicist.

    Hlo need help : why we study covariant form of various eq( dirac eq for QM) ( cause the eq is covarient so why change its form)
    Also why their is no explanation to contravarieny form?
    Thank you

    • @Phymaths
      @Phymaths  ปีที่แล้ว

      We use covariant form of equations so that we don't have to check if the resulting expressions transform correctly under Lorentz transformations.
      There is no "contravariant" form of equations. Physicists use the word "covariant" to refer to the equations that transform correctly under Lorentz transformations and also to refer to vectors that transform like the gradient operator. So, this is just a semantic confusion. Again, there is no contravariant form of equations.

      @Jcactus213 hello my friend:) In 2023 I had tried this exam for doing PhD in mathematics. Even though I am MSc Physics they allow us to do PhD in maths if we could clear their entrance and interview, I knew some BSc level maths when I gave tution for some students then I prepared for a whole six months to touch over the MSc Maths topics and I realized that my six month preparation was no where near the exposure to maths a student will get in Two year MSc maths.. I didnt got selected. But now I am fully foccused on CSIR NET FE 2025:) from 2019 after my MSc I have been trying and trying for different exams and it is from the last two years that I am properly preparing without my thoughts wandering off to other topics. Last time I was close to JRF by 4 marks and this time I am preparing my very best to obatin the JRF for my PhD in Physics:) So do not loose hope... with focus and determination you try and try again , each time improving more and more by analysing what went wrong the last time and finally you will be able to do it. Each day you ask yourself "If the exam is today have my preparation reached to a level that is enough to get the JRF? if not then what am I to do next? which portions should I understand more? should I change the book I have taken for QM?" like this always keep a self talk with yourself to stay focussed and motivated:) All the very best my friend✌:)❤

You are truly passionate to do Physics as you have given up your job for it and is preparing your best to clear the exam and that's truly amazing. In the upcoming 28 days stay focussed and cover all the important problems from previous year IIT JAM question papers and workout as much as problems you can and on the day of the exam you reach the exam centre in your most focussed and prepared state ever and give it your very best! Unlike TIFR which do not even publish our entrance score( if I remember correctly) JAM however is a very good opportunity as if we get pass the cutoff we will get a chance to get into MSc alteast somewhere in India and we can grow from there:) All the very best my friend stay focussed on your dream:)

      It is good. You are in a quite good position. As you have done your bachelors in physics, you do have the skills that physicists require (e.g. coming to the right answer by intuition.. something that pure mathematicians don't always have when they work on theoretical physics) and you have done your Masters in mathematics which gives you mathematical tools that you can use in your research.
      So, in short, yes you can definitely contribute to theoretical physics. Good luck.

      No where in this video a comparison between Sen and Sudharshan has been made. It is very possible that if you compare their contributions, Sudharshan's contributions come out as more important. It isn't claimed here that Sen is the biggest Indian physicist in the modern era (that's simply not true). However, using the words like "this Ashoke Sen" is very very disrespectful towards him.

He fully focus on his Physics explorations and didn't care about who comes first or second.. and I am sure that Ashoke sir too fully focus on his works instead of caring about first or second. If you see both of their interviews this thing is clear right?
      I know Hassaan through TH-cam for more than a year and he is person who gives respect to both of these Physicists without any partiality and also tries his level best to bring to us science ideas as genuine as possible. He is currently in his last year of research so have a lot of academic things to get organised. But I am sure(just my opinion, I am not putting you under pressure Hassaan) that oneday he will make a video of Sudharshan sir:) like you I too would love to hear about his life and works:) I am living in a neighbouring district to where Sudarsahan sir used to live in his childhood so I feel more thrilled:)
