Thanks a lot professor, you came up with very specific examples and it helps a lot, keep doing this tutorials please. correct the mistake at the end of the video 3x10^1 instead 3 x 10^2

Michel van Biezen commented on 05 Sep 2015

+xLegiolx Found it. Thanks

Pascual Chavez commented on 04 Sep 2015

3x10^2 = 3 x 100 = 300. I guess you mean 0.3 X 10^2.

Michel van Biezen commented on 05 Sep 2015

+Pascual Chavez 3 x 10^2 = 3 x 100 = 300 0.3 x 10^2 = 3 x 10^1 = 30

Hi Lisa, Thank you very much for uploading this video. I am currently in my 5th week of the IB program in Australia and my Physics test is this coming week so this has been a massive help to me!! Thanks again.

Excellent demonstration! Thanks for making it so complete. : )

Hi Mr Thornley! Just wanna ask what if the calculation involves both addition and division at the same time? How should I do the uncertainties?

Richard Thornley commented on 10 May 2015

+Hiu Ying Bernice Chow - Bombax calculate the addition first (follow decimal places) then do the multiplication (follow the significant figures)

Sasha Moore commented on 11 Jan 2015

Can you explain the differences for IB physics? 

Richard Thornley commented on 11 Jan 2015

nope - no idea!

Ashley Wiggin commented on 09 Nov 2014

where did you get the 0.500 kg/l from?

Richard Thornley commented on 10 Nov 2014

1.00 divided by 2.00 = 0.500

Constructive criticism: I am having a hard time following this. I am very familiar with significant digits, but when you speak of precision, accuracy, uncertainty, and how they relate to each other and to significant digits, I feel like you sort of throw the terms around without really explaining.

No comments? Well here is one. Hope that makes you happy professor, I basically should now get an A in 1a.

It was so hard to focus with the breast feeding video on the side bar.

DarknessnLight Creations commented on 11 Feb 2011

Just wanted to say thanks! Your video helped me a lot!

bronze83 commented on 09 Mar 2010

Excellent. Thanks. A very clear and precise lesson.

easy to follow and understand...liked it!

What about calculating the "propagated uncertainty" when we have a complicated formula (not a simple formula like that presented here for multiplying length by width to get area of desk table)? This complicated formulas are the real headache of all serious users.

Mohamed Fahmy commented on 12 Sep 2015

From where did you get the 3 mm uncertainty of the length and the width? - If we know this 3 mm uncertainty everything is straightforward, but a priori we do not know this 3 mm value.

Mohamed Fahmy commented on 16 Sep 2015

Where can we stay "tuned"? There is is noway to find your next video, Sir.

I've been searching for this for 20 minutes. Thank you so much.

Thank you very much! You explained it very clear!
