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? They are a little circle and Dr. Quantum

Good
What's the difference between the worlds in which the characters live in? In the world of the circle, of two dimentions, only you can see left, right, forward and backward, while that in the world of Dr. Quantum, of three dimensions, you can see these previous and too up and down.

What does Dr. Quantum decide to do? Dr. Quantum decides to talk to the little circle and explain how is the world in three dimensions, with different perspectives, and finally allowed go toward the world of three dimensions.

What does this cause to the other character? The other character when leave is surprised with the new world.

III. After watching the video, please answer these questions. How many dimensions do you know? Please mention them and define them. I only know of three dimensions:
 * In the first dimension you can see only points.
 * In the second dimension you can see left, right, forward and backward. That is, plane figures such as squares, circles, rectangles, etc.
 * In the third dimension you can see left, right, forward, backward, up and down. That is, figures how pyramids, spheres, cube, etc.

Would you like to live in a two dimensional world? Why? I __do__ not like to live in a world of two dimensions and less in only one dimension, being a point, a circle or a square. This is because a world in less than three dimensions would be restricted. But live in a world of more dimensions could be great.
