Human head and brains
The human head contains 22 bones, consisting the cranium and the facial bones. The cranium is formed by 8 bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone in the back, the ethmoid bone behind the nose, and the sphenoid bone. The face consists of 14 bones including the maxilla (upper jaw) and mandible (lower jaw). (The skull has many little holes in its base which allow the cranial nerves to travel to their destinations.)
The cranium protects the brain, which, for an average adult male weighs about 1400 gram (49oz). The brain of Russian novelist Turgenev, weighed 2021g (71oz), Bismarck's brain weighed 1807g (64oz), while that of famous French statesman Gambetta was only 1294g (46oz). Female average brain mass is slightly less than that of males. The largest woman's brain recorded weighed 1742g (6oz). Einstein's brain was of average size.
An elephant's brain weighs 5000g (176oz or 11 lb), a whale's 10000g (352oz or 22lb). In proportion to the body, the whale has a much smaller brain than man. This seem to give man the edge, until it was discovered that the dwarf monkey has 1g of brain per 27g (0.95oz) of body, and the capuchin monkey has 1g of brain per 17,5g body, whereas man has 1 gram of brain to 44g of body.
Most scientists believe that "photographic memory" is a myth. Clever people train their brains to remember well. In fact, as humans we simply do not remember things well. Of the three beings known to be able to recognise themselves in the mirror, the orangutan, the dolphin and the human, only the latter turns around and instantly cannot remember what his/her own face looks like. (Try drawing a picture of yourself without looking in the mirror:)
Brain power
The human brains consists of more than 100 billion neurons (nerve cells) through which the brain's commands are sent in the form of electric pulses. These pulses travel at more than 400 km/h (250 mph), creating enough electricity to power a lightbulb. The brain consumes more energy than any other organ, burning up a whopping one-fifth of the food we take in.
It is estimated that the mental capacity of a 100-year old human with perfect memory could be represented by computer with 10 to the power of 15 bits (one petabit). At the current rate of computer chip development, that figure can be reached in about 35 years. However, that represents just memory capacity, not the extremely complex processes of thought creation and emotions.
But consider this: for all the complexity of the brain, you still have only one thought at a time. Make it a positive thought.
Factoids
One-quarter of the brains in used to control the eye. We actually see with our brains, with the eyes basically being cameras.
You're born with 300 bones, but when you get to be an adult, you only have 206.

How to?
How to HACK using Google? Google is a very very very powerful tool! If you know how the Internet works and you know how Google works, you can find out some "very secret information" from the dark corners of the Internet. You see, Google tries to "index" everything that is on the Internet. What does "index" mean? Basically, "index" means, read and remember! You see, Google is reading websites on the Internet 24 hours a day. It is looking at new websites and new web pages. It looks at each web page and finds out what the web page is about. It decides how good the web page is and also decides many other things about the web page... Google does all this so that when you search for something using Google, it can give you the most relevant results from among the web pages it has visited. This is what we mean when we say that Google tries to index everything on the Internet. Now, the part we are interested in: Since Google indexes the Internet, we can find things that are hidden in all the corners of the Internet. If some one has put their password on the net, you can find it! If a big online shopping site, has put all the credit card information of it's customers on the net, you can find it! You can find some very interesting things if you know how to use Google! This article will teach you the basics of how to find cool things using Google. indahowto.com does not endorse hacking! Hence, we shall not be showing you how to get "credit card details" and "passwords" etc... But we will show you how to find e-books, movies, games, software, music etc. that is stored on the Internet... Next -
