How big is a billion?How big is a billion?

(9:43) There's more to this question than you might imagine. Mathematician James Grime and physicist Tony Padilla from the Numberphile team discuss millions, billions and trillions. It's surprisingly interesting. www.numberphile.com

As I was taught many years ago a million was 10 to the power of 6ie 1 followed by 6 noughts. A billion is a thousand million and a trillion is one million million. Or ten to the power of 12..These figures are too big to conjure up in the mind are irrelevent in terms of visualisation..The only article I ever saw which gave any way to visualize this amount was a picture of a 1000 dollar wad of notes at 100 dollars each. This then pictured a six foot high football pitch holding a billion dollars. Try and imagine a 1000 football pitches filled to six foot with 100 dollar bills..It al ends up out of the realms of our imagination.

He never said what a thousand (1,000) is in the long system. Since it's based on (1,000,000) to the powers of 1,2,3, etc., it completely skips the thousands and it's an extremely important stepping point.

1 thousand is 1 million to the power 1/2. Then, 1 thousand million is 1 million to the power 1.5. Try it out on a (scientific) calculator.

Latest comment: I agree that's the correct math but it's not very friendly when you have to use fractional powers to derive important numbers like a thousand.

All because of one stupid American, no doubt!
