you not call as the ratio all the

circumference of a circle
to its diameter so how far and a circle

divided by how far across keep on ever
since
people for starting about mathematics or

geometry pies blame on the most
fashionable numbers and applies in so

many other areas
mathematics and geometry engineering the

physics
and it's driven some people absolutely

man in your text or instead
mathematical disc jockey Adam Spencer
is a big big fan hi a number
it appears in the weirdest places for

example
take the sort of wine the rivers that

flow across gently sloping plane
it's not exactly clear why but measured
actual length or width of divided by the

distance from source to ocean as the
crow flies
and the result he's on half rage hi
3.14 hi it's a god-given number
and it appeared everywhere from

probability to pendula
as pointed out by Matt Synthesia Rob

East away
ok and by the way and over GE pendulum

length divided by the acceleration due
to gravity
the pendulum swinging quite free then

it's always a marvel to me
but each take place each talk the

grandfather clock
is to pie root out energy now maybe it's

not such a surprise for the pendulum
you've got to hide because after all

pentium is a fix
taken it's creating a bit of an archive

a circle but there are other situations
where you think
surely have got anything to do with a

circle
let's suppose wanna a really big sandy

beach on some
desert island and got a very large break
and each the key the right car exactly 1

inch apart
he just run miss rake along the beach

and you can match you create a lot two
parallel lines
you happen as well to have a matchstick
which is exactly one inch long and he

did not stop talking this much that
landing it on your power lines
well if you do this experiment thousands

of times
the chance landing on one of the lines

exactly to have a pie
if you kentucky's I'm completely random
