Kikes and Diegos speaking class

Today Kike and Diego made their speaking class.
Kike tallked about GPS.---> GLOBAL POSITIONING SYSTEM
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.
