• Scientists have discovered that copper pollution of the atmosphere occurred about 2500 years ago. This was discovered by analyzing ice cores from Greenland. The pollution was attributed to the Romans who used copper for military purposes and to produce coins.
• A thimbleful of a neutron star would weigh over 100 million tons.
• Polar Bears are nearly undetectable by infrared cameras, due to their transparent fur
• Hydrofluoric acid will dissolve glass.
• If you stretch a standard Slinky out flat it measures 87 feet long.

Just like there are carnivorous plants, there are carnivorous sponges, which trap passing prey with tentacles and engulf them, eventually digesting them. As with carnivory in plants, the sponges resort to this method in environments where their primary nutrient source (particulat matter filtered from the water) is not availible in sufficient quantities.Mokele

Here's another one: there is an ameba size cellular organism called the "slime-mould slug. These amebas gather together in long strands when their food source shrinks. These strands act like worms that move away from the water to a high point, splitting the worm to go around both sides of things. Then they compact themselves one upon the other into an upward-like worm so that those on the top are exposed to any animal that walks by. They are picked up in the animals fur and, like a bee taking pollen, it is spread to a new territory for the slime mold slug.

Google is deploying spy planes that can show you sunbathing in your garden. They will be able to show things 4 inches wide. That doesn't worry me although 4 inches long might!

Water is the only compound known to be less dense as a solid then a liquid.

 

 

The only mammals to shed saltwater tears are aquatic mammals and humans.

 

 

anti-matter is the most expensive substance on earth, costing (at low estimate) $25 billion / gram.

Where do u buy anti matter?

[ajb]

Where do u buy anti matter?

 

The CERN gift shop?

 

Seriously now, antimatter can be found quite naturally all around us, just not in any great quantity. One has to use artificial methods to create antiparticles and this produces not exactly huge amounts.

 

For example, it has been estimated that it would take 100 billion years to produce 1 gram antihydrogen using the methods employed at CERN's ALPHA experiment.

Part of the formal training of machinists in the US is the pronunciation of numbers, critical in machining to avoid ambiguity. The word "and" is used only to locate the decimal point - 1101.01 is read "one thousand one hundred one and one hundredth", and no other way.

 

(n.b. among machinists, 1101.0011 is read "one thousand one hundred one and eleven tenths).

 

btw: Water ice is not the only solid less dense than the corresponding liquid - among the elements alone, gallium, germanium, and bismuth expand when solidifying. Several compounds do that as well.

Hydrofluric acid is a weak acid by class but it is far more corrosive than hydrochloric acid!

Koalas are teh only animals besides humans and other primates that have fingerprints.

Naegeli–Franceschetti–Jadassohn syndrome (NFJS) sufferers, among other things, have no fingerprints.

The word hundred is derived from the word “hundrath”, which actually means 120 and not 100.

 

[DrKrettin]

The word hundred is derived from the word “hundrath”, which actually means 120 and not 100.

 

I think it's changed its meaning since Old Norse.

 

In Old Norse hundrath meant 120, that is the long hundred of six score, and at a later date, when both the six-score hundred and the five-score hundred were in use, the old or long hundred was styled hundrath tolf-roett ... meaning "duodecimal hundred," and the new or short hundred was called hundrath ti-rætt, meaning "decimal hundred."

Oh ok, I recently read about it so shared here. By the way thanks for detailed information.

Here are my facts, my first post here :

Did you know that there are 206 bones in the adult human body and there are 300 in children (as they grow some of the bones fuse together).

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

The most dangerous animal in the world is the common housefly. Because of their habits of visiting animal waste, they transmit more diseases than any other animal.

Snakes are true carnivorous because they eat nothing but other animals. They do not eat any type of plant material.

The world's largest amphibian is the giant salamander. It can grow up to 5 ft. in length.

The ears of a cricket are located on the front legs, just below the knee.

The first electronic digital computer (called ENIAC - the Electronic Numerical Integrator and Calculator) was developed in 1946 and contained over 18,000 vacuum tubes.

there used to flea circus too , according to the " Ripley's believe it or not " book

performing stunts to firing mini canons .

and about snake , how do u know that ... if they accidentally end up eating a leaf ?

Not due to the transparency, but to the very effective insulation. This includes control of the blood supply to the skin, as well as hollow fibre fur. 

I remember years ago installing passive infrared detectors in my burglar alarm system. You could defeat the detectors, by holding up a high tog duvet in front of you, and moving slowly. A polar bear would have hot spots, like the eyes and nose, and breath, so I would think that a PIR detector would pick them up in a cold space.

The likelyhood that two people ever shuffled a deck of cards (52 count) identically is very, very low. It is not expected to have ever occurred in the history of mankind nor is it expected to occur in the future of mankind!
