I've seen 30-40 mins videos that explain all this in a horrible way impossible to understand. You with 8 min video explained it perfectly. Thank you very much, this really helpful for my tomorrow exam.
@@RichardWongPhysics After I watched your video, I was able to find a mistake in my calculations. Nothing particularly difficult, but I just could not see it :)
It is based on the idea that most variable and random processes has a Gaussian distribution (the bell curve), whose width (or fuzziness) is characterized by the standard deviation. Quadrature is similar to how we find the new standard deviation of the resulting variable when we combine standard deviations of different variables together. You can maybe see why if you look at the function describing the Gaussian distribution.
Thanks for your nice explanation. I have one unclear point about minimum reading of the measurement even it is not a matter of the point what you are discussing hear. The minimum measurement we can get on measurement A is 0.05 . Can we have a measurement like 8.52. I thought it is 8.55 or 8.60. Regards
There are no strict rules. It really depends on your specific measurement, method, and devices. For example, it is possible for your measurement to have a precision of 0.01 so it can read 8.52, but then the number fluctuates, so you estimate the uncertainty to be 0.05.

You are most welcome. Happy to help!
This was really helpful for my 1st year physics labs. Thank you
Glad you found it useful. Cheers!
Really really so thankful for u ❤ u saved me before final exam 😂❤
Thank you so much sir (from India🇮🇳)..U explained really well.
You are most welcome. Happy to help.
You are a legend. Thank you. 🥳🥳🥳🥳🥳🥳🥳🥳
absolute legend
You saved my day! Thank you so much!
You are most welcome. What about uncertainty propagation did you find difficult?

Why we use specially the quadrature in calculation of the uncertainty??

best video evarrrrr

this clears out everything for me. Thank you very much!
Super helpful. Thanks so much!
Thank you. Happy to help.
Mega based tutorial. An example with summation would have been great, but evidently not necessary.
Thanks ❤
