Quirky Science Facts!

An amazing list of facts about cats:-
Cat Facts

I have had cats all my life but there were lots I did not know.

The fact about them predicting Earthquakes I know from personal experience is true.
My cat was howling one night and woke me, I went to find her she was in the bath. Very strange, she hated the bathroom and never made a sound at night.
Then everything started to sway and she slid around the bath howling as the earthquake hit.
She knew the earthquake was coming long before anyone and obviously, and probably correctly, thought the bathroom to be the safest place.

Our cat 'Candy" can predict; up to ten hours, in advance, when a storm will hit.

During a well balanced meal:
One in three bites, will be food that has been touched by a Bee.

...

50 gets 2^50

so,

2^50 x Page width = total width of fold stack.

now 2^50 is around 1.1 x 10^15 u.

Now, distance between earth and sun is.. um... 1.49 x 10^11 meters.

So width of single page (according to that claim) = (1.49 x 10^11/1.1 x 10^15) ~ 1.3 x 10^-4 m

which is about 0.01 millimeters... the width of normal papers!

Wow! He was right!

Paper folding competition, anyone?

Can someone find the chemical formula for a piece of papaer(any kind) I tried and cant find any

I think I can prove that *fact* wrong with that formula thanks

It used to be the accepted wisdom that you cannot fold paper more than 8-10
times. But a young, Californian maths student has just managed 12 folds
Folding Paper in Half Twelve Times
or better explained
Folding Paper - Great Moments in Science - The Lab

In fact, if you had a sheet of paper, and folded it in half 50 times, how thick would it be?
The answer is about 100 million kilometres, which is about two thirds of the distance between the Sun and the Earth.

Actually, you give the reason why a paper can not be folded more than (about) 10 times : paper has a thickness.
This makes that when folding the outer side of the fold will be longer than the inside. So either you have top stretch the outer side, or to shrink the ineerside, or find a way to do both at the same time.
Folding a paper double twelve times will require an extra thin and very elastic paper.

See Mythbuster's Episode 72 (Underwater Car). They folded a football field sized piece of paper 11 times with a steamroller.

Technique is everything: as the episode notes, its *much* easier to fold repeatedly in one direction rather than turning the folds 90 degrees at each fold.

I Just got off of work from the local newspaper...........167,529 Copies, Signitures, whatever you want to call them, Four Editions with press speed at 72,000pph, and....Ya Know, I'm gettting sick of this folding paper bit

Ya wanna a Quirky fact, ?????????
