Video+2

I. Before watching the video:
 * Great Job **[[image:Santa_down_the_chimney.gif]]

1. What do you think the video will be about? I think it will be about quantum mechanics, probably the general concept and a few theorems.

2. What do you think "flatland" means? I’ve never heard the term. But I think it is related to a flat surface of some kind.

II. Now click on the following link and watch the video. While watching, please answer the following questions: http://www.youtube.com/watch?v=BWyTxCsIXE4&feature=related

Who are the main characters in the video? Dr. Quantum and “Little Circle”

What's the difference between the worlds in which the characters live in? Dr. Quantum lives in a 3 dimensional world (like ours), and Little Circle lives in a 2 dimensional one.

What does Dr. Quantum decide to do? He decides to show Little Circle the third dimension and give her a new perspective.

What does this cause to the other character? She turns into a sphere.

III. After watching the video, please answer these questions.

How many dimensions do you know? Please mention them and define them.

This is a tricky question.** Jiji... That was not my intention. ** I can perceive 3 dimensions: the first if we pick a point in space and draw a line that touches it, then give it a direction we would get a forward and backward movement, we could get a second dimension by drawing a perpendicular line to the first one, so we could get right and left movements, finally we could get a third by drawing a line perpendicular to the other 2 lines, and get an up and down movement.

But the question was about how many dimensions I //know// and I heard from my physics teacher that some theories use up to 11 spatial dimensions. And in mathematics we commonly use n-dimensions.

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

No. Because I have already seen the third dimesion. I would feel that I’m missing information every time I stare at something.
