Why do people reverse in the mirror, but didn't reverse it? Have such a weak answer: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ----------------------- When you look around, it looks around, and there is no reverse. That is an illusion. In fact, there is no reverse left and right in the mirror, just before and after your body.
The answer should be your eyes are left and right, not up and down.
The reference object is different. When we re-select a mirror and a reference object, there is no problem in the body.
Before and after the body, if you want to go up, you go to haha.
Because the left and right can be, it can't go up and down.
If the mirror is indulged under the top or the foot, it will not be upside down ----------------------------------- ----------------------------------------------
Many people seem to have no modern physics knowledge
Very shallow reason is that the people are symmetrical rather than up and down, this is nothing to do with the eye structure. You can use only one eye or to get the same concuression with the same conclusion. The reason is that the generation of the left and right and up and down. of. For a biological, it is generally adjacent to the stereotype in the direction of its normal active state, reverse. Before the direction of the head (eye), the opposite is the opposite. At this time, it can be set to the four directions before and after the up and down.
Left definitions are: extending your right hand, thumb and 4 fingers on a plane and is vertical. If 4 fingers are in front, the direction refers to the direction of the thumb, then the direction of the palm is left.
From this definition, we can see that if a person doesn't know which hand he is right, then he can't judge around (nonsense). This concluded that the concept of around: The concept is concept, not to express the specific noun expressing this concept) never confirmed, just a conventional thing.
Look at the image of an object of a mirror, a three-dimensional space: The object Z coordinate is multiplied by -1 by the plane where the plane is located is X, the Y-axis. It can also be seen as a reference system with this object, maintaining any two-dimensional constant, and the third dimensional reverse result.
Now we can explain why mirroring can be reversed, can't you reverse? what? Still not? Upper, before, left, left and right as three-dimensional, the result of the priority of the image is to change the direction of one-dimensional direction. That is, reversing up, left and right, arbitrary groups before and after. However, up and down, for the person, it is determined according to the definition. That is to say, as long as people have not changed, it will be fixed, so they only have left left.
