This has helped so much thank you for your video!!!

[@ferdlc7757]

my god I finally understand the difference. I was confused on whether they were all different values but you clarified that they are all the same uncertainties just expressed in different form. Thank you so much

[@AndyMasley]

So happy the lecture was helpful! It's surprising how badly it's explained sometimes

[@tahiranwar4707]

Oh sir and finally I understand thank you very much

[@Moiez_khan]

Very helpful explanation 👍👍

[@AnsonTanTheTradveller]

Nice Video!

[@parameshwarhazra2725]

please sir can you recommend a book based on the basics of uncertainty, errors and graphs for physics lab? lots of love from India

[@yunyutang9982]

Thank you so much

[@nhaz652]

as for the unit, im still confused at where should we put it... cuz in the practice example, the units were written beside the uncertainties. kindly advise.

[@CyprianKosi-ws7vc]

Excuse me 🖐️
Th last example you did for number 2 on both sides - 1874+or-40: why did you round the number uo to 3 significant figures? and 990+or-6 : why did you round the uncertainty to 1 significant figure?
Thank you 🙇🏻‍♂️🙏

Im confused - I got 4/pi on the exam, and I thought I explained it thoroughly. Isn’t the fractional uncertainty (delta(A))/A. ?
Where A = the area of the circle
Delta(A) = the uncertainty of the area
???

Thanks

[@giemar8307]

A big help to us... thank you Sir

[@user-zg4ob2bl2n]

But why wouldn't you use the full range of the number to express the fractional uncertainty?

[@fidias9]

Can i have this slide please?

[@ammar7497]

Hi! I'm from Pakistan and I'm in highschool. This isn't even in my syllabus, but as I was studying difference between error & uncertainty I was curious (as I love physics) about these uncertainties.
You helped me a lot Sir. Thanks

this is weakkkk

[@AndyMasley]

Nooooooooo
