-! *YOUR  CHALLENGE*  :  Your image in a mirror.
-! 
-!  ![](objet_image_defi_v2_300.jpg)
-!
-! We all have the opportunity to look at ourselves in a mirror. We see our own image. But perhaps it is interesting to take the time of interrogative observation, and then to test yourself.
-!
-! _Do not look at the answer, take time to think, a few days if necessary. The time to build your mental representation of the phenomenon, to formulate it in words is important, a thousand times more important than the ephemeral instant where you read the fews words of the solution._

-! I choose.

-! * Is my image simply located in my mind, or has it a location somewhere in space?
-! * If my image is localized, what is its position?
-! * If my image has a position, does it have a size? Is she taller or smaller than me?
-! * If my image has a position, and as it is made of light, can it illuminate a screen?
-! * If I retreat a little from the mirror, I see my image decreasing slightly. Why? Is the size of my image really smaller? Or does it keep its size and I'm the one who sees it smaller?
-! * Can I imagine to see more or less tall an image that has a well-defined size?
-!
-! These questions that I ask myself about my image, I have to ask them about an real object that I see in front of me.
