Do we know these facts?

How do reindeers survive in the extreme cold? Most animals don’t eat moss. It’s hard to digest, and it has little nutritional value. But reindeer fill up with lots of moss. Why? The moss contains a special chemical that helps reindeer keep their body fluids warm. When the reindeer make their yearly journey across the icy Arctic region, the chemical keeps them from freezing—much as antifreeze keeps a car from freezing up in winter
The female lion does more than 90% of the hunting while the male simply prefers to rest!
The vocabulary of the average person consists of 5,000 to 6,000 words
No word in the English language rhymes with "month"
The word "racecar", "kayak", and "radar" are the same whether they are read left to right or right to left.
A flute made of bone is the oldest playable musical instrument in the world. It’s a flute carved from a bird’s wing bone more than 9,000 years ago. The flute was discovered with other flutes at an ancient burial site in China.

Know our Brain !

brain of total body weight (150 pound human) = 2%
Average brain width = 140 mm Average brain length = 167 mm
Average brain height = 93 mm
Intracranial contents by volume (1,700 ml, 100%):

brain = 1,400 ml (80%);
blood = 150 ml (10%);
cerebrospinal fluid = 150 ml (10%) (from Rengachary, S.S. and Ellenbogen, R.G., editors, Principles of Neurosurgery, Edinburgh: Elsevier Mosby, 2005)
Average number of neurons in the brain = 100 billion
Number of neurons in brain (octopus) = 300 million (from How Animals See, S. Sinclair, 1985) Number of neurons in Aplysia nervous system = 18,000-20,000 Number of neurons in each segmental ganglia in the leech = 350 Volume of the brain of a locust = 6mm3 (from The Neurobiology of the Insect Brain, Burrows, M., 1996)

Humans use only 10 percent of their brains

This media darling has been around for at least a century. Fortunately, it's just not true. MRI imaging clearly demonstrates—with fancy colors no less—that humans put most of their cerebral cortex to good use, even while dozing. Another Myth!?

The religion of the future?!!

The religion of the future will be a cosmic religion. It should transcend a personal God and avoid dogmas and theology. Covering both the natural and the spiritual, it should be based on a religious sense arising from the experience of all things, natural and spiritual as a meaningful unity. If there is any religion that would cope with modern scientific needs, it would be Buddhism.

Phlogiston theory?

noreply@blogspirit.com () — Mon, 03 Oct 2005 09:57:08 +0500

Like alchemy to Chemistry Phlogiston is to Physics. Though disproved now, this theory was supported by big names of the 18th Century. I read a small info on net today on this interesting fact...

phlogiston theory , hypothesis regarding combustion. The theory, advanced by J. J. Becher late in the 17th cent. and extended and popularized by G. E. Stahl, postulates that in all flammable materials there is present phlogiston, a substance without color, odor, taste, or weight that is given off in burning. “Phlogisticated” substances are those that contain phlogiston and, on being burned, are “dephlogisticated.” The ash of the burned material is held to be the true material. The theory received strong and wide support throughout a large part of the 18th cent. until it was refuted by the work of A. L. Lavoisier, who revealed the true nature of combustion. Joseph Priestley, however, defended the theory throughout his lifetime. Henry Cavendish remained doubtful, but most other chemists of the period, including C. L. Berthollet, rejected it.

So rationalism in science ( and also in anything like Religion, Philosophy ) is to be taught to our own students. Let them doubt first! Never discourage them as Doubting Thomas!!

Watch the Earth now from above!!
