Mar today has talked about Twitter.
Twitter is an online social networking service and microblogging service that enables its users to send and read text-based posts of up to 140 characters, known as "tweets". It was created in March 2006 by Jack Dorsey and launched that July. The service rapidly gained worldwide popularity, with over 300 million users as of 2011,[6] generating over 300 million tweets and handling over 1.6 billion search queries per day.[3][8][9] It has been described as "the SMS of the Internet."

It has over 300 million users.

We think that is an interesting program for people who want to know or learn about things of other countries or people, but we wont make an acount now. 

Peters and Anas speaking class

Peter has talked about Spotify yesterday.
Spotify is a program in internetwere you can listen to music. There are 2 different versions of Spotify,the free one and the one were you have to pay.If you dont pay you cant download music and you can listen to it only on your computer.
We think that it isnt such a good program because you cant own the music you only can listen to it and there arent some important groups like THE BEATLES.

Anas has talked about MarvinSketch, this is a program for phisics.

MarvinSketch is an advanced chemical editor for drawing chemical structures, queries and reactions
Things you can do:
1.Chemical structure drawing
2.Reaccion drawing
3.Query drawing
4.Atom and Bond properties
And many other things but its complicated and to much to explain, we think that its a quite interesting program for those people who need it.

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites.
We talked about utilities of GPS, we use it to find places, in military, medicine,police...
There are also games you can play with GPS systems. (finding and highding,geocatching..)

Diego tallked about vector lines.

A portion of the vector field (sin y, sin x)

In vector calculus, a vector field is an assignment of a vector to each point in a subset of Euclidean space. A vector field in the plane for instance can be visualized as an arrow, with a given magnitude and direction, attached to each point in the plane. Vector fields are often used to model, for example, the speed and direction of a moving fluid throughout space, or the strength and direction of some force, such as the magnetic or gravitational force, as it changes from point to point.
