@@g.o.a.t4674 I don't know your formal educational background, but it seems your comment befits your user name!! 😃😃 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!! 🙏🇮🇳🙏

@@sumantabanerjee8287 Sen's work is in string theory ie which is o ly mathematical and not even partially correct. Abhay Ashtekar's Ashetkar variables are like how F=ma is to lagrange's equation. Ashtekar formalism is a partially Quantized Gravity. You know only prof amalkumar raychaudhuri. There was also a physicst called Datt he was the first one to predict the existence of black holes and Vishweshwara also kid learn things

Thank you for this video! The amount of work that geniuses like Sen do is just unbelievable. Almost equally unbelievable is how they got Ashoke Sen to dress up so nicely for the Breakthrough Prize ;) I agree that he is also an amazing teacher and I recommend everyone to find lectures by Sen on RU-vid. He explains things so well and he is so utterly unpretentious. A true genius!

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 .

@@ikshu0769after your 12th, get enrolled at some college, and do your BSc well. You could also look at the BS-MS degrees at the different IISERs and at the IITs. ICTS doesn't have a bachelor's programme. Anyway, after your Bachelors or your BS-MS, you need to sit for one or both of the following exams - TIFR, JEST. Get a good rank in both, get called for the interview, clear the interview and behold, you'll be enrolled :)

Lakn ye boht hi ik afsoos hai.. K pakistan mai even boht sare theoretical field mai phd kr rahai hai... But boht hi kam jantai us ko... Ye mere apna khial hai k us jaise pata nahi pr paida hota ye nahi... Lakn koi us ko janta tk nahi... So i appreciate your efforts... Amazing

I did not get the conclusion of the black hole entropy calculations. Did the final results accounting for the multicenter states match up with the loop quantum gravity results or not?

@Phymaths 8 месяцев назад

So the result that didn't match the result from LQG was regarding the entropy of Schwarzchild black holes. That result did have a disagreement with LQG result and I don't think it was resolved.

@Goldslate73 14 дней назад

Hey, i really hope you read this... Im in my 3rd year of BTech and I want to pursue theoretical physics (cosmology and quantum gravity) and im looking for ways to make the switch efficiently. 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 have studied quantum mechanics, cosmology and special relativity from the Stanford University open courses. Leonard Susskind.

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 7 месяцев назад

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.

I want to be a physicist too " sir I've passed my class 12th with decent marks ' is bsc physics worth doing ? Or there's any other way to pursue carrier as a physicst Pls guide me sir I'm from Bihar

@Phymaths 8 месяцев назад

Well I don't know about the quality of Bsc that you are considering to do but as a general remark, I would say that to pursue your career as a physicist, it is very advisable to study physics in your undergrad and your graduate years. So, I would say that yeah, go for a physics degree if you want to become a physicist.

Sir i have not a msc physics . I am come from msc math department . I have a question can a mathmatician contribute in theortical physics . I have a physics in undergraduation . Not in msc .😅😅

@Phymaths 8 месяцев назад

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.
