"Whats a simple test of sanity?

According to some psychiatrists, its as simple as this:

you're sane if you are able to take another person's point of view"

The Odd Body 2 by S Juan is full of such facinating trivia.

For example body size.

US surveys show that men who are 173 centimetres tall, consider themselves short.

In fact, they are exactly average.

 

Human beings on average are probably taller today than ever before in history (better nutrition & disease prevention etc.,).

But Cro-Magnon human was taller than today's average human.

 

Cro-Magnon also had a larger brain mass.

No Old World monkey can swing by its tail! Tail-swinging is an exclusive New World invention!

 

Another quirky monkey fact is that New World and Old World monkeys can be distinguished by their nostrils - American monkeys' nostrils point sideways, whereas European, African and Asian monkeys' nostrils point downwards.

 

Betcha didn't know that!

 

Well, now you do!

What about the patella?

Kneecap?

How the patella is connected to the femur

The whole patella is attached to those tendons and is not connected to femur or tibia by any means other than the tendons.

The patella claims for itself alone that it is not attached to another bone by ligaments but is connected by the tendons which bypass the knee joint and is very powerfully bound to the femur.

I am going to bed and cleaning my teeth!

Don't do it! It'll be a holocaust!

 

Quirky Fact #12334:

Mammalian blood can hold more than 30 times the amount of oxygen in suspension than the same volume of water, thanks to heamoglobin!

 

The purple blood of molluscs and bivalves can only hold about 8 times as much.

My teeth are going all furry

 

How Much is a Million? Billion?

 

The last line in the post (a trillion seconds is 31,688 years) is even more remarkable because :

1 year = 31,557,600 seconds

 

No wonder that some people think they recognize the number PI is such numbers !

 

And still with that number PI : a tidal cycle takes approximately 4 PI hours !

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.

Lets see if I can use simple logic to see if this is right.

 

If width of paper = x

 

1 fold gets two papers in a stack.

 

2 gets 4

 

3 gets 8

 

4 gets 2^4

 

...

 

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 :lol: 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.
