Literally explained it better in 20 minutes than any teacher at my school ever has in 2 years.

Somebody give this man a medal.👏👏

How uncertain I was on this topic:
My uncertainty after watching this video: ±0.0001

great video mate, helped a tonne + or - 1kg

I was so confused after doing uncertainty in class but this video cleared it all up. Many thanks, just started A level physics and I think I'l be back to this channel a lot over the next 2 years...

This video will never get it's relevance will keep resurfacing timely.... lucky are those who view it while they need to.

Hey, thanks for all the videos you make on physics, it really helps me consolidate my knowledge coming up to the AS exams, and I also like your sense of humour. It always makes me chuckle hearing you complain about how rubbish a past paper question is or whatnot

[DanielKim-dkim]

wow this is what I actually wanted. A lot of textbooks didn't coverup different types of uncertainty explicitly. Thank you so much

MY TEACHER SPENT 4 HOURS TEACHING THIS AND THIS VID MADE ME UNDERSTAND IN 20 MINS TYSMMM KING

[OWTShark]

You made me understand it in 2 minutes when it takes school a year and still doesn't make you understand the subject well, thank you 🙏.

I just become a professor in uncertainty in 21 minutes

[vhaalgorn]

This was so satisfying to learn for some reason, it just makes sense!

[jordanaraujo]

Legit watching this the night before let’s go

[legittheral]

Wow this was long but extremely useful. Thanks alot, I finally get it.

Some digital device reading can have zero errors if they aren't zeroed(calibrated). Eg. There's a zero button in digital scales, but if you press it when there's a weight on it, it will use the weight as the starting point of the reading instead of 0, hence zero error.

I’ve got my final physics paper today. Big thank you for all the videos you’ve posted

[lindamercan]

Easy explanations that clarify all the intricacies in a difficult topic.
Thanks so much.

when I become a Billionaire I will donate 1 Million ± 10% money to your channel :)

[shayan]

ur my hero. literally im in yr13 and I never understood any of this and you changed it.

[dodadoda]

1. Nice vascularity sir.
2. I'm 100% certain I am acing this topic after your clear explanation, I'm grateful.
