Question Asked: How Does BlueTooth Work?
BlueTooth, for those that don’t know, is a relatively new technology (the last few years, anyway), that allows two electronic devices to talk to one another, over a wireless connection. Generally, BlueTooth is a cell phone and headset pairing. However, it can also be a keyboard and computer, a computer and a mouse, an iPod and a pair of headphones. There are plenty of BlueTooth devices out there these days.
The technology is routed in a sort of radio wave with varying frequencies. The two BlueTooth devices are “paired” together, and can then communicate. The pairing process is pretty simple, and is more or less means you’re making each device agree to talk to the other, and vice versa.
There are great details (greatly in depth, that is, not like “Wow! Great!”) on the BlueTooth website: BlueTooth.com
Where does the name BlueTooth come from? It gets its name from Harald Bluetooth, who was the king of Denmark in the late 900s. Under his rule, he achieved many important triumphs, including uniting Denmark and Norway and introducing Christianity. Bluetooth is named after this king to show the importance of bringing together different devices and communicating with one another.
Question Asked: How Does a Plane Fly?
There’s four elements to making a plane fly: thrust, weight, drag, and lift.
The aeroplane is designed in a way that all of the parts of it contribute to one of these four factors, in some way.
The engine creates thrust.
The ailerons combat drag.
The flaps combat the weight.
As air travels over the wing, it creates lift. The shape, length, and size of the wing is all carefully calculated out to each individual plane (or jet, for that matter.)
LiveScience has a great article on the ins and outs the subject of flight. Read it here: link.
