Hello sir, I've been following your channel from quite some time, and i must say you are one of the best teachers of physics on youtube..you explain the concepts really well and i love the way you speak..😊
Dear professor Das, a humble request for a series on Tensors. Though there is a lot on net, yet I and many more are addicted to your style of teaching. Your lectures are explicit and vivid. I hope you must ponder over my request.
Sir, please could you make a video on how you achieved proficiency in all computational language and softwares? During which year, whether in your MSC or BSC you learned them? How do we learn these languages? From which place you learn these language? Please make a video on it.
For the Nuclear physics which book is recommended sir and your videos are very usefull for me in developing knowledge. Very very thanks ❣️ for videos sir.
sir can you please make a playlist of lectures on statistical physics and quantum mechanics i am really struglling with all the complex math and waves functions. its a humble request sir. do consider it
hi sir, do you happen to know if "Six Ideas That Shaped Physics Unit R" and "A Traveler's Guide To Spacetime" by the same author are the same text (practically speaking) or they are different?
Good books on Special relativity 1) Special Theory of Relativity - Banerjee and Banerjee (PHI learning) I used it during my PG days. 2) Relativistic Mechanics - Satya prakash (Also contains a good course on GTR and Cosmology to a good extent) 3) Fundamentals of special and General Relativity - k.d krori 4) General theory of relativity - S.P puri 5) S.T.R - S.P puri I personally used 3,4 and 5 for my RELATIVITY SPECIAL PAPER ! and you are a good Teacher, really appreciate your effort !
The famous derivation of the time dilation equation can be derived in 2 contradictory ways. The first paragraph below describes the situation with Sally aiming a flashlight straight up and down so that Sally sees the light moving straight up and down and John is outside the spaceship and sees the light forming a triangle with the floor of the spaceship. The second paragraph describes Sally aiming a flashlight towards the left while the spaceship moves to the right. Now the situation is exactly reversed. Sally sees the light forming a triangle with the floor and John sees the light bouncing straight up and down. Sally is in a moving spaceship. John is outside the spaceship. Sally is moving to the right at .6c. The height of her spaceship is .8 light-seconds. If Sally has a light clock with the light bouncing straight up and down the light will make a 3-4-5 right triangle from the viewpoint of John. If the change in time for Sally is delta T_o and the change in time for John is delta T then the following equation can be derived: delta T = delta T_o/((1-.6^2)^.5). So .8 seconds for Sally = 1 second for John. Now Sally has a light clock but this time she is holding a flashlight at an angle of 53.13 degrees above the horizontal and pointed to the left. Now the leftward movement of the light exactly matches the rightward movement of the spaceship from John's viewpoint. Now the light is bouncing straight up and down from the viewpoint of John and the light is making a 3-4-5 right triangle from viewpoint of Sally. If the change in time for Sally is delta T_o and the change in time for John is delta T then the following equation can be derived: delta T_o = delta T/((1-.6^2)^.5). So 1 second for Sally = 0.8 seconds for John. The 2 equations are in direct contradiction to each other. Special relativity is falsified.

Thomas Moore's books do not get enough love! His Six Ideas series and his GR workbook are all excellent.
How are u sir? I am greatly benifitted by your certain videos regarding NUCLEAR PHYSICS. And I answered perfectly in VIVA❤️
Sir, please could you make a video on how you achieved proficiency in all computational language and softwares? During which year, whether in your MSC or BSC you learned them? How do we learn these languages? From which place you learn these language?
Please make a video on it.
Thank you, sir. I`m your great fan.
Introduction to ED by Griffith's is good one r for beginners❣️❣️
Sir please make comprehensive videos on other topics like statistical physics, quantum mechanics, solid state physics, etc.
You are doing a great job of teaching.
Thankyou very much sir . You helped me a lot through your videos a big thanks.
And yes you are a friendly neighborhood PHYSICSMAN.
Excellent Recommendation !
Many may refer to these as SR/GR rather than STR/GTR. If either are encountered, they are the same thing.
Underrated channel
I am addicted to this channel.
Can you do one about nuclear physics? Thank you so much! Love your content
For the Nuclear physics which book is recommended sir and your videos are very usefull for me in developing knowledge. Very very thanks ❣️ for videos sir.
Thanks for your help. Regards from Mexico 👏🏻
Sir, please make a special video on "space time causality".
Thanks a lot sir...your videos help me lot to build concept 😃😃😃
sir can you please make a playlist of lectures on statistical physics and quantum mechanics i am really struglling with all the complex math and waves functions. its a humble request sir. do consider it
Sir i want to build my concept of TENSOR from ground up
Can you please give me some recommendation on how to do it properly.
Watch Pavel Grinfield lectures on RUclips
Sir please start lectures on general relativity
How do you feel about Kip Thorne's "Black holes and time warps"? I've heard that it is a great introductory book for special relativity.
It is a nice book about black holes. And also much history about scientists is given.
Sir kindly do more these types of videos on different topics like mechanics , electrodynamics ,quantum mechanics,relativity etc overall all physics
First read Tatsu Takeuchi’s illustrated guide to relativity to get feeling of SR
we want more from this series sir for every topics please sir
Sir please upload a lecture on General theory of relativitu
Thank you soo much sir.. Plese make a book recommendation for GTR also
Which subject will be started now,?
Great video
Sir how is the mechanics by Devid Morin❤…!
ITS STR part is my favourite
hi sir, do you happen to know if "Six Ideas That Shaped Physics Unit R" and "A Traveler's Guide To Spacetime" by the same author are the same text (practically speaking) or they are different?
Sir make video on book recommendations, on others topic of physics.
Good books on Special relativity
1) Special Theory of Relativity - Banerjee and Banerjee (PHI learning)
I used it during my PG days.
2) Relativistic Mechanics - Satya prakash (Also contains a good course on GTR and Cosmology to a good extent)
3) Fundamentals of special and General Relativity - k.d krori
4) General theory of relativity - S.P puri
5) S.T.R - S.P puri
I personally used 3,4 and 5 for my RELATIVITY SPECIAL PAPER !
and you are a good Teacher, really appreciate your effort !
Hello ! Sir , can you tell me which books are best for Nuclear & Particle Physics? Plz , give recommendation lists. 🙏
I've some nice ideas about quantum gravity. We can publish some papers together.
thanks a lot sir
sir mujhe tensors padhne hai
can you please suggest that from where i can start....
for kelppner and kolenow get older edition... newer edition has fewer solved examples and nothing new...
Hello sir are you from west Bengal ?
I am from west bengal
please sir start a video series of GR.
Why not Tipler Llewellyn 's modern physics. List is incomplete............
Sir,books for nuclear physics which contains more theory....plz tell me...?
Sir I respect you a lot love you sir
The Kalyani publication classical mechanics book is very good for special relativity
What you think about electromagnetism book by hc verma ?
when will you teach quantum?
Sir, please make a lecture on minkowski space- time
Already done ruclips.net/video/-PV1JqV3blY/видео.html
Thank u sir
Sir, please recommend for GRe also
Thanks sir
Sir, the concept of str is wrong. Can you please listen to my arguments ?
Tell how.....
sir for nuclear and particle physics also
Sir I Am new and I want to learn special relativity, guide me
god bless u teacher
Thanks
Can you tell me the price ₹ /.
