Walter Lewin, thank you so much. You are a champion! This video made me feel like I can do this semester's work if I keep on seeking help and working my way forward bit by bit.

the great Walter Lewin

I m her after reply of Professor Walter Lewin to my comment. Thank you professor.

Thanks Dr. Walter, thanks to the uploader

Thank u so much! The poor man version helps a lot

Thanks very much sir . I really appreciate it

great teacher......i have ever seen.Thanks WALTER LEWIN

Extremely thank you sir. You have solved my very big mystery!!!

Thanks doctor. You are great

Thanks Dr you are amazing as ever

Sir kindly make video on uncertainty measurements from basics

Si how you write the error in the distance as +or-20

Also, say I have datas for x and y alongwith the respective uncertainities. If I have to plot x vs log y, then how do I calculate uncertainity in log y? For instance, if y= 54.3 +or - 0.5, then what will be log y?

So, are you saying, only use the poor man's version in this class, and later, when you're working, use the correct version? And, that correct version, I'm guessing, is instead of adding uncertainties you take the square root of the sum of the squares?

Thank you professor

CAN U TELL HOW TO CALCULATE UNCERTAINTY OF MEASUREMENT LIKE MEASURING TAPE , MICROMETER & VERNIER CALIPER

Sir why did u write +-1 in 2nd prob?

Who are the girls whose photographs are pasted on the professor's cupboard???

Bedankt

What's up with the pictures of those girls btw?

required more details

What is that correct version, Sir?

Sir i meaur the lenth of a page. It comes out to be 15cm. How i can tell about the error in this messurent

@3:32 how do you know the percentage error?

Damm 1/10*100=10% 20/400*100=5% (46.7-34.5)/2=6m 40-+6 6/40*100= 15% (40/100)*15=6

Sir but how the error % in b square is 20%.. Sir Pls elaborate

nicely put for an old git!
