Earth Hour!

Please do participate! How? Just turn off your lights at 8:30-9:30 pm tonight (March 27 2010).

By doing this, we can conserve energy a LOT. This is a global activity and if all of us would turn off the lights at the same time, that'll be a lot of energy saved.

Come to think of it, it's best to do it once a week. :)

phones.

Have you ever noticed that people are really attached to this electronic device? I have, and I am struck with that "sickness" too.

The earliest and easiest mode of communication before telephones is by simply shouting at the person you want to call for. Then people invented drums and other objects as a mode of communication.

Of what I believe, cellular phones started from land-based telegraphs. These devices use the Morse code, the kind of code that is used where a series of dots and dashes are used.


Eventually, technological advances were made. And so the huge, "mechanical" phones are made. Alexander Graham Bell was the inventor of this cool prototype.


Because of this, there was a sudden need of people to have telephones. Why? because it eased communication with other people in far places.


DynaTAC was a series of cellular telephones manufactured by Motorola, Inc. from 1983 to 1994. It was the first line of cell phones commercially produced by Motorola, with the first member of the DynaTAC series, the 8000x, being the first cell phone to receive FCC acceptance in 1983. DynaTAC was actually an abbreviation of Dynamic Adaptive Total Area Coverage.

After that, different phone companies stared to spring up and went up for the race for better, faster and smaller cellular phones. Nowadays, you can see models and concept phones that can be made in the future. These two will set as examples.


Cool eii? I like them too. ^^

Most educators say that this wonderful device is becoming a pest, as they interrupt a person's schedule like schoolwork or other activities. Well, it's true, in any way or another.
