I am an American and I love Johnny Ball! Is he fairly well received in the UK?
He's a legend, many kids from the 80's learned so much from him while being entertained. But sadly he disappeared from our TV's by the 90's
Lel whose teacher made them watch this?
lol
so théy could take a smoke break :P Why bother with getting 600 pingpongballs and numbering them all several times, if you can just wheel in the TV and VCR :P
Yeah
He came into our school the other day lol
Great to see Johnny Ball on TV, he's like the school teacher one instinctively listens to.
Saw this ages ago, yet I still remember it. What a great teacher
They've put this 'capture and re-capture' stuff in our Edexcel GCSE maths
He looks so happy
W Johnny ball, he's straight bussin fr bro

I've been on youtube every day for nearly 4 years and you're the first comment out of thousands i've read that made me laugh out loud the most i have in a whole week. Thank you

Rhod haha funny
What a lot of ping pong balls
life on a plate show was good hope some1 uploads it
Check the chalk noise
I love 💘 johnny ball
He looks like my uncle frankie
Nah, Frankies taller.
Thanks for still showing this...way? Maths is maths is maths is maths. Divide it and split it . Sad times for Britain
Jonny Ball wrote 100/17=5.88x100=588 which isn't very mathematical but he's a legend so should we let him off?
Hello ms prior
Interesting! besides I´ve learned something new today :-)
"that would take too long" Yeah, this way is DEFINITELY faster than simply counting them :P
(I know, I know, just kidding)
Friday euro millions today go 4 it it goes to good cases
Congratulations :L

Johnny Ball. The staple of my childhood TV learning.
Love that guy.
I would have counted the balls in each direction and multiplied them. But this seems a much more interesting method.
interesting
Johnny ball has been my child hood hero and to this day.
Nice one mate
great stuff from the lad
thank you Johnny Ball, very cool.
Cheers mate
old man!
Did i just see a Land Rover used as taxi :) wooooow :) awesomm
no
Is there a mathematical name for this estimation because I searched for a theory about this situation, but I could not find anything?
It's literally said in the video. It's called Capture Recapture .
The method in order to work it out for anything is: The first sample divided by repeats then times by second sample.
@@klstay9704 I'm having serious doubt about this guy if he couldn't even listen to the explanation for longer than a minute...
my teacher made me watch this and i love this video ever since. thank u mr teacher
