Quirky Science Facts!

In our corner of the Milky Way, the density is such that a sphere with a radius of 200 light years contains 200,000 stars!

Ah. What a number density!

 

Now lets take the other face of it.

 

The matter density appears to be around...

 

[math] 10^{-20} {Kg}{m^{-3}}[/math]

Damn.

Approximately 99% of the Homo sapien genome is identical to the chimpanzee genome, our closest living relative.

 

It is estimated that the Neandertal shares 96% of the 1% difference with Homo sapien.

 

The Neandertal shares the remaining 4% of the difference with the chimpanzee.

I heard that the Orangutans where more like us.. :shrug:

They look more like us

but

in everthing I have read; it has been chimps- as the closest -genetically

If protons and neutrons were 10cm across, then quarks and electrons would be less than 0.1mm in size, and the entire atom would be about 10km across!

The word asteroid is not just the name for large space rocks, the word is also means to be shaped like a star, and is hence used as a description of star fish!

 

Bet you didnt know that one!

A large swarm of desert locusts can consume 20,000 tons of vegetation a day.

The temperature can be determined by counting the number of cricket chirps in fourteen seconds and adding 40.

 

(I'd like to actually test this "theory")

Whoa thats cool! natures own thermometer :)

 

Flea's can jump 130 times higher than their own height. In human terms this is equal to a 6ft. person jumping 780 ft!

There are more living organisms on the skin of a single human being than there are human beings on the surface of the earth.

Consider the word 'consider':

 

It literally means "to be with the planets"!

 

How's that for deep thought?

Fact: No matter its size or thickness, no piece of paper can be folded in half more than 7 times.

 

Does anyone know the science behind this? :)

no idea, but I have experienced it first hand

 

The ratio of a number in the fibonacci sequence to the next tends towards the golden ratio (or golden section, golden mean) phi = 1.61803.. this number is has some interesting properties.

Such as:

1/phi + 1 = phi, this can form a quadratic equation and allow for a solution of phi. This ratio comes up a few times in nature,

 

Eg The ratio of successive phalangeal bones of the digits and the metacarpal bone approximates the golden ratio. It is also claimed that the number of bees in a beehive divided by the number of drones yields the golden ratio!

15 million blood cells are produced and destroyed in the human body every second.

Hummingbirds are the only animals able to fly backwards!
