Why Is Bluetooth Called Bluetooth?

When two devices need to talk to each other, they need to have a handshake on various parameters before the conversation starts. The first agreement is on the medium – will they use wires, or talk over some wireless signal? Bluetooth is one such wireless signal (protocol) over which two (or more) devices communicate over.
Strange name though isn’t it – are the bluetooth waves invisible but blue and shaped like teeth? Wrong! There is absolutely no relation between the name and the meaning.
The Bluetooth protocol was created by Ericsson (pre-Sony Ericsson) which is a major Swedish telecommunication company. They named it after the Danish viking king, Harald Blåtand. As legend goes, Blåtand had the blessed ability to bring people negotiate with each other, and come to talking terms.So skilled was he, that he was able to unite Denmark and Norway together! The literal translation of Blåtand means blue-tooth, hence the name Bluetooth for the protocol. It does precisely what Blåtand did – lets two wireless device to communicate with each other!
The Bluetooth symbol has HaraldBlåtand’s initials inscribed into it (in Runic). The two lines sticking out of the back of the B actually represent a Runic H – that's H for Harald .The B for Bluetooth also stands for Blåtand!

How do erasers erase?

Contrary to popular belief, pencils aren't really made with lead, and haven't been since Roman scribes wrote on papyrus -- that's a common pencil myth. So if you chew on your pencils, rest assured you won't become ill from lead poisoning (although that's not a free pass to snack on a No. 2). Today's pencils are made with graphite, water and clay (which is used as a binder), and pencil lead has been made this way since Nicolas-Jacques Conté invented the mixture in 1795 [source: Ritter].

 They weren't topped with an eraser tip, though, until about a century later. And it's this companion to the pencil, the eraser, that we're interested in here.

Erasers eradicate pencil markings by lifting graphite from the paper you've written on. As you write, particles of graphite from your pencil mingle with and cling to particles in the fiber of the paper. Here's the science: Modern erasers are almost always made from petroleum-based synthetic rubber compounds, typically polyvinyl chloride (they're no longer made from natural latex rubber, which is an allergen for some people). Because the particles in the polymer that make up an eraser are stickier than paper, those graphite particles get stuck to the eraser instead. Some erasers are stickier than others and absorb graphite particles more easily, giving you a cleaner, less-abrasive result.

What happens if I put sugar in someone's gas tank?

For some reason, there's a common rumor about sugar and gas that's been around for decades. Supposedly, if you pour sugar into someone's gas tank, you will disable the car. The sugar is supposed to react with the gasoline and turn into a semi-solid, gooey substance that totally clogs up the gas tank, the fuel lines, and so on.­

It sounds great, especially if you have a grudge against someone. The problem with this rumor is that it simply isn't true. As it turns out, sugar doesn't dissolve in gasoline. Pouring sand into the gas tank would have about the same effect as pouring in sugar. The sand or sugar might clog up the filter, and that could disable the car, but it's not a sure thing.

So what do you do if you really do want to disable someone's car? Pour in some water. Gasoline floats on top of water, so if you pour in several cups of water, the fuel pump will fill the fuel lines with water instead of gasoline and the car would have some major problems.

How to fix Memory Card formatting problem ?

Majority of Peoples faces this problem so here is the solution

Some times our Memory Cards stop working after we have formatted them from our Computer and not from mobile. If you read user manual of your Mobile you will find a warning message asking you not to format phone memory of your mobile and memory card from computer, you should use mobile.
