Groucho's Fact Hunt


Sir Isaac Newton was knighted in 1705 - but not for being the greatest scientist of the past 2000 years. Not even for his civil service as Master of the Royal Mint [pretty important job at the time]. It was part of a dodgy scheme cooked up by his patron the Earl of Halifax to swing the seat of Cambridge the way of the Whig party in the next election [Sir Isaac stood but lost the seat].
 

Why exactly 4.5 billion? Isnt Universe like 13billion years old or something...
Big Bang happened about 13 billion years ago. Interestingly, and surprisingly (given the speed of light is a maximum velocity), the known universe is much, much greater than 13 billion light years in radius...it's 94 billion light years in diameter. (one light year equates to 10 trillion kilometres).
If you could fold a piece of paper (0.1mm thick) in half enough times, it takes 103 folds to create a thickness of paper enough to span the known universe.

If you wanted the paper to have a volume of 9.4X10^26 cubic metres (i.e a tower of paper 1 metre wide and 1 metre long and 9.4x10^26 metres high), you would require the surface area of your starting piece of paper to be 9.4x10^20 square kilometres...which would wrap a sphere 12600 times bigger (in diameter) than our Sun...that's 20 times bigger than our solar system (in diameter)....so a BIG piece of paper.

Another interesting thing : √ 3+√ 3+√ 3 = √ 3 x√ 3 x√ 3 (i.e √ 3 x 3 = √ 3^3 (NB ^ is 'to the power of' sign) √ 2+ √ 2 = √ 2 x√ 2 x√ 2

That was easy

Funnily enough, that's what my nan said to me on her death bed.
