Image taken from. [] on Aug 12th, 2009 II. Now click on the following link .and watch the video. While watching, please answer the following questions: []

Who are the main characters in the video? the Dr. Quantum and the circle.

What's the difference between the worlds in which the characters live in? The difference between the two worlds is that in the "flatland" __not up or down, only left, right, front and back.__ **confusing **  What does Dr. Quantum decide to do? Dr Miguel tries to convince the circle **about the fact that **there are more than two dimensions.

What does this cause to the other character? the circle was surprised because he was convinced of the existence of a third dimension.

III. After watching the video, please answer these questions. How many dimensions do you know? Please mention them and define them.

- In the first dimension can be seen only the length of objects, for example: a line. - In the second dimension can be seen the length and height of objects, for example: a triangle or square. - In the third dimension can be seen the length, height and depth of objects, eg a sphere or a cuboid.

Would you like to live in a two dimensional world? Why?

no, because you can not perceive things as in the third dimension, you see every plane, there is not depth. In adition, being in a world of two dimensions limit your physical actions, you can not jump, can not see the sky or the mountains because is probably does not exist.
