1. If you watch the whole video series……..your concepts will be as strong as Ambuja cement👍

2. thanks sir

3. Wow,……great explanation sir

4. Nice sir maja aa gya abhi tak esa lecture ni mila 4 saal purana hai par abhi bhi iske comparison ka koi nahi hai is platform par

5. Thanks🌹🙏

6. This was very Helpful for beginning Special theory of relativity

7. Thank you for Making Concepts clear

8. What an awesome lecture never got such gr8 information on SR

9. i cant tell you what i got ….. what a beautiful explanation 🤗🤗🤗🤗🤗🤗🤗🤗🤗

10. This is the best introduction to special theory of relativity

11. Sir, you are the best:)

12. Such a down to earth explanation. I've found it really helpful! I would finish watching the rest of the videos within the lockdown days😊

13. Thank you

14. Sir, from which book you prepare these lectures.or give me recommended book name of STR plz sir

15. Sorry sir I'm asking out of video but i think you only answer who i know…..the ques is….every galaxy have its blackhole at its centre the universe start from big bang like nuclear bomb and it expand and expand but there is a time when it stop to expand and start to shrink and…..is all the matter again goes to none or shrink to a single point…..sir i hope u will answer soon

16. Sir what if two bodies are accelerating in deep space so how to know the actual acceleration of the body…..

17. Thx sir….

18. Thank you Thank you Thank you for having good audio quality

19. 19:20–20:00

20. Sir for an inertial frame of reference accn can be experienced ..but only if external force is applied.
    M i right

21. Sir can you explain why velocity of light is not relative

22. 23:00 to 30:00 is confusing

23. Amazing lecture

24. The most clear explanation for reference frames and real forces , thank you sir.

25. You are best sir

26. Great explanations….. I'm thankful to you provide such typical type of course so easy manners ….Thanks nptel.

27. There is one problem when he talks about measuring speed of light in different reference frames. His conclusion is right while i doubt his argument. He argues that different observers in different frames measures speed of light differently because frame is moving too, CORRECT! but then he argues that are the values of permeability and permitivity different in different frames? I find this wrong argument as the observer is NOT measuring the ABSOLUTE speed of light, all he is doing is measuring RELATIVE speed of light from his reference. When he will measure the speed of light (absolute) from a light source in his reference system then he will be actually in a position to compare observed speed of light with maxwell's formulae

28. Thank you very much sir…

29. Thanks for reply..sir..listen once more…We can just take a reference frame outside the earth (in space) to get the absolute rest condition …but why we needed to consider a medium such as ether to overcome the problem??Yes,I understand this theory can explain other demand such as propagation of light,let just forget about that …. general theory of relativity sustains as long as we hold the existence of ether medium….but why go to the idea of ether in the first place where we can just claim space as as a reference frame as absolute rest???

30. Sir …can you explain again why we came the idea of ether to eliminate the the difficulties of the different speed of light for different reference frame??I don't understand that part..

31. thanks to nptel and Prof. Shiva Prasad Sir for this great lecture series.

32. Great sir please put all lacture of bsc first year

33. What an excellent lecture sir

34. 1st comment of my life on YouTube and it's AWESOME

35. in subtitles lawrence force is written which is lorentz force ….. i think

36. Fabulous amazing

37. Sir i have a question. Why we can't compare the speeds observed from two diffrent frame of refrences?

38. sir, can you please name some good books to read on the topic special theory of relativity

39. Very nice sir .I have never seen as logical explanation of relativity theory as you gave

40. The more he explains, the more questions I have. Strange as it may seem, this means that I understand what he's saying. Thank you for the amazing lecture series! Greetings from Michigan 🙂

41. What a remarkable explanation of the ideas of reference frames and the ether. Professor Shiva deserves applause.

42. This guy is a really good teacher. I'm looking forward to the next lesson. Thanks for the upload!

43. really this lecture is much helpful for me.i have increased my knowledge level in this topic.

44. Excellent explanation

45. This is AN AMAZING course. I´ve never met before such clear but deep ideas on teaching about SR…..
    The only improvement I can think of would be a similar course in General Relativity: Such course would be AWSOME if taught by this incredible teacher. Thanks for this course from Spain.

46. el baile de los que sobran suena al principio csm xd

47. hai sir
    will you please explain me once that the point you have said at 28:20 in the above lecture that you had said the both frames s ans s' are intertial frames of references but the relative velocity between the both frames of references does not depend on time . My dought is why it doesnt depend on time.
