Imagine that you are standing in front of a mirror and looking at your reflection.

Don't you see anything strange in it? Take a closer look... Why does the mirror reflect from left to right, but not from top to bottom? Legs, arms, cheeks - changed places, but the head still remained on top, and legs - below. Why did the hands change places, and not the legs with the head? Weird.

There is also a longer version of this question, which I posted on VKontakte. There's also an additional example with "AMBULANCE" written on the hood of the ambulance, also reflecting horizontally, but not vertically.

If you see this question for the first time and have not thought about it, I strongly recommend that you read what it consists of and think about why. Otherwise, it will not be interesting further and there may not be enough strength to read the entire text.

For those who have already puzzled over this issue for several days and who really want to know, finally, what's the matter, I publish the answer with detailed explanations.

The riddle is complex. While answering it, several times you think that you have already come up with the right solution. But a day passes, a second, and you realize that something is missing in your explanation, and the riddle has not been completely solved. You can’t understand what exactly is missing - and you start explaining it again. And again you come up with a solution. And again, as time passes, it begins to seem somehow unfinished.

The answers are very different. There are those about which you quickly realize that they are erroneous: this is the structure of the eye or the brain (the eye does not distinguish where the light came from, which formed the picture, from the mirror or not; the brain turns the image from the retina in the same way, not distinguishing between the picture from the mirror and the usual picture); two eyes, so you are guided by the direction connecting them (close one eye - everything will be the same); vertical and horizontal rays of light fall at different angles (they fall at the same angle).

And there are interesting and partly correct answers, but none of them is clear anyway.

« Why solve it? Everything is obvious. Let's build a geometric projection by following the rays of light - and the reflection will turn out just like that. Explaining why it is like that is the same as explaining why blue is blue and green is green.».

This is true. But let's consider the image and its reflection separately from each other. After all, one and the other is taken from planes parallel to each other. And in these parallel planes, you and the mirror, there is no information about which axis to reflect. Any physical properties of the reflective material and space are the same vertically, horizontally, along an inclined line. But stand in front of a mirror. The looking-glass world and the person in it changed their direction only horizontally. But vertically everything remains the same. Don't you think this is strange?

« The left hand on the reflection is on the left, and the right hand is on the right. The head is on top, the legs are on the bottom. Left-right, top-bottom - these are just some conventions, and there is no contradiction at all».

This is so, there is no contradiction. But let's say you want to see something on yourself in a place that is hard to see, for example, on your face. We approached the mirror and found the desired point in our reflection. They began to reach out to her hand. If you need to move your hand up or down, lead it where you need it. But when you need to move your hand to the side, first you lead it in the wrong direction, you get confused. Familiar feeling? Why problems arise with the horizontal direction?

« The thing is that the mirror is vertical. If it were above you as a mirror ceiling or below you as a floor, you would be reflected from top to bottom, and not from left to right.».

Sounds nice: a mirror in a vertical plane, the direction of reflection is horizontal; mirror in a horizontal plane, the direction of reflection is vertical. But these are different systems and they cannot be so easily compared: in one case, you and the mirror are in parallel planes, in the other case, in perpendicular ones; in the first case the horizontal line of reflection direction does not cross the mirror, in the second case the vertical line crosses the floor or ceiling. These are very significant differences and, as often happens, a simple and beautiful-sounding explanation turns out to be erroneous.

Let's go back to the original situation. The mirror is in front of us. We stand in front of it and see that it swaps legs, arms, cheeks - i.e. reflects horizontally. And let's lie down in front of the same mirror on our side. In the reflection, the legs, arms, cheeks will still change places, but not the legs with the head! Represented? Those. It turns out that the mirror is already reflecting vertically ...

Stop. It is important. It just reflected horizontally, and now we lie on our side, and it reflects vertically.

If a mirror reflected both horizontally and vertically, what would happen to the image? Let's see:


The image would be the same as it was, only rotated 180 degrees!

This is very important for understanding what reflection is, what its nature is. It turns out that double reflection translates the image into itself, up to rotation. And you can reflect on any axes. Let's say we can take two axes rotated relative to each other by 45 degrees.

The image remains the same, just rotated 90 degrees (45° x 2).

Reflection, it turns out, generally exists only in one way. Those. for a given image, you can come up with only one reflection, but you can’t come up with a second one. We can reflect on any axis, rotate and get the same reflection that we did on the other axis (this can be seen from the pictures above).

I repeat: the reflection is formed along ANY axis. And a mirror cannot simultaneously perform a reflection operation only along two axes. And it turns out that the reflection in the mirror that we see can be obtained by doing this operation along an arbitrary axis, and then rotate the result so that the legs are at the bottom.

Ok, the reflection is unique up to rotation and can be built along any axis. But back to the mystery. Why does the mirror seem to choose a specific axis of reflection - such that the legs are located below? Or is it that we notice a specific axis of reflection ... Then why exactly it?

The thing is, we didn't complete the task.

We talked all the time about the image and its reflection. But we lacked a vantage point! We guessed the location of the observer on our own.

Those. it is necessary to set the conditions of the problem normally and understand where the observer?

When we think about this riddle, what do we do?

At first we seem to put the photographer to us and photograph our reflection. Then we put the photographer to the mirror and take a picture of ourselves. And we begin to compare these two photos. Do you agree? But these photos are not clear how to compare! Because when we moved the photographer from one point to another, we inevitably TURNED him. How we rotated it and took photos:

Those. we rotated the observer in the HORIZONTAL plane, around the vertical axis.
Let's see what happens if we rotate the same virtual photographer in the VERTICAL plane.

Represented? When the camera rotated around the horizontal axis, it flipped over. And it turned out that the same mirror reflected us vertically! Note that only vertically - the hands did not change places, there was no reflection horizontally. Here it is!

Moreover, let's rotate the photographer in an inclined plane.

(The camera remains rotated to the bypass plane at the same angle). The mirror reflected us at an angle! Blimey.

Those. those two photographs that we took once can be compared by rotating them relative to each other at any angle. And it will be the same as letting our virtual photographer on planes with different angles of inclination.

As you can clearly see, the mirror does indeed reflect in any direction. Which one we notice depends on the angle at which we compare the image of ourselves and the reflection. Or, which is the same, at what angle we send our virtual observer in order to take two pictures, and then compare them.

Those. we stand in front of the mirror, see our reflection and imagine that the mirror has turned us vertically. To do this, we only need to clearly imagine how we will direct our photographer to turn around in a vertical plane.

Why do we direct it predominantly in a horizontal plane? Why, when comparing two photographs, do we put them so that the legs in the image and in the reflection are from below? Because we are used to walking on the ground, we move mostly in a horizontal plane. Although we live in a three-dimensional world, we think in two dimensions. To remember that there is an up and down, you have to strain. If a person looked up and down more often and moved freely in this direction, turned - like a fish in water, did somersaults, somersaults, walked on his hands - perhaps it would be less difficult to imagine turning in a vertical plane. It would be easier to mentally see how you (or rather your virtual observer) takes off and turns over, moving towards the mirror - and sees you turned upside down.

In films, a plot is often used: one person is hiding from another somewhere under the ceiling or climbing a tree. The villains (or vice versa, the forces of good) are looking for him, looking around, but not up and down. Why? Because we're used to seeing it that way. As a result, they do not find the fugitive, and the hero manages to break away from the chase.

Or another way to imagine the riddle. This is when a person "inhabits" the reflection, imagining that in the mirror this is him. For example, this is how a person feels when he picks, excuse me, in his teeth and, seeing a defect in his reflection, cannot decide where to move his hand: to the right or to the left (up or down does not cause difficulties!)

Why it happens? Intuition strongly suggests that the head should always be on top, because in life we ​​are used to seeing people with their heads up and their feet down. And, although the mirror shows some kind of abstract reflection with which we can compare ourselves as we want (build it along any axis of symmetry), in this reflection we try to see ourselves, first of all, as the same person we saw before, i.e. head up and feet down. The picture in the mirror is distorted, but there is a nuance: the left and right halves of the human body are extremely similar in appearance. And the brain, analyzing, generally speaking, an incomprehensible distorted picture, explains it in the simplest way: you see an ordinary person in the mirror, head up, feet down. That hands have changed, you don’t pay attention to it! The object has already been identified - a person. And only upon closer examination, you notice that his right and left halves have changed places. And then you start to wonder: why exactly did the right and left swap places? But because the choice was already made by you, and before you asked this question. This is how a distinguished horizontal direction arose in our perception. And this, in particular, is manifested in the confusion of horizontal movements, when we control ourselves, guided by the reflection.

But let's try to understand what is wrong, by comparison, like the case with the photographer. We can compare ourselves and the reflection in different ways. Usually a person, "inhabiting" his reflection, rotates around the vertical axis by 180 degrees. Let's simplify: this is the same as a person turning his back to the mirror, standing on the floor, and comparing himself with the original reflection. It turns out that the head and legs have not changed places, but the hands have changed. All the same classic case with a horizontal direction. Now look at the video and imagine that there is a mirror in place of the wall.

The man first stood in front of the mirror, and then stood in a handstand. The original reflection, in comparison with it, had its legs and head swapped, but the hands did not change places! But the techniques are equivalent: turn your back to the mirror, standing on the floor, or stand on your hands, as shown in the video! The angle is the same, 180 degrees. Only the axis of rotation differs. Do you agree? If this action were typical. If you yourself walked on your hands, then on your feet. If you saw other people behaving in the same way, perhaps this mystery would not even arise. He wanted to - turned around, standing on the floor, wanted - stood up on his hands. In the first case, people would notice that the mirror can reflect horizontally, in the second, that it can reflect vertically. Maybe on an inclined axis, people would begin to notice the reflection more easily, having gained freedom of movement in space upside down and at angles.

Everything is explained, as you can see, simply. It's all about rotation around different axes and correct comparison with the original reflection. If you "move" into the reflection around the horizontal axis, then everything changes. As we can see, this way of presenting the riddle is similar to the way of presenting it through a photographer. Only here we turn not the photographer, but ourselves.

So why do we have such a hard time turning around the horizontal or some other axis? And why does such an error even occur when people present a riddle? To summarize all the reasons I found:


  • We live in a space where top and bottom are always rigidly set. We walk mainly in horizontal planes, we turn only to the left to the right; we don’t somersault, we don’t stand on our hands and we don’t walk on them, we don’t fly like astronauts in weightlessness. We find it hard to imagine that we can navigate differently and see the world upside down or at an angle;

  • When we choose how we compare ourselves to the reflection in the mirror, we are based on how we see other people. And we adjust the answer to what our intuition tells us: the head should always be on top. It is difficult for us to imagine another more general answer in order to find a way to solve it;

  • Our right and left sides are very similar, the human body is symmetrical. This also inclines us to the fact that the left and right halves have changed. It is more difficult to imagine, even to assume that the head was in the place of the legs, and the legs were in the place of the head. (Or even on an inclined axis: the right ear and the left heel have swapped places).

Obviously, the reasons are not in the reflection, as in a physical phenomenon, but in our perception.
In the reasoning that describes the perception of a situation, the main mistake usually lies in the fact that people do not specifically specify two positions of the observer and do not try to consider all the ways of moving from one position to another.

Remember, we lay down in front of the mirror and asked ourselves why it still swaps ears, arms, legs. Test yourself - if you understand what is written here, you will find an explanation.
And an exercise that you may like: ask yourself the conclusion that the mirror reflects you along an inclined axis, and try to imagine, explain this to yourself. Either through a virtual photographer and two INDEPENDENT photographs, or by turning your body half a turn around any inclined axis lying in the plane between you and the mirror.

Well, that's the explanation.
It was necessary to completely specify the system: where the image, reflection and observer are located. And it became easier to solve the riddle, to understand what was the incompleteness of the reasoning.

In the case of the inscription "AMBULANCE" the situation is completely different. It cannot be put on a par with this riddle, because the positions of both images and mirrors are already rigidly set in it, i.e. reflection, and the observer.
And based on the fact that the observer is sitting vertically in his car and wants to read the text in the rear-view mirror, as usual, from left to right, the technicians put the inscription on the hood of the car, reflecting the inscription horizontally, from right to left. I must say that they could reflect it vertically, but, when applied, they would rotate it 180 degrees.

We have considered only the case when the person and the mirror are parallel to each other.
And what about the mirror ceiling?

The mirrored floor (the same as the ceiling) you have seen many times. This is a tree and its reflection in the lake, which you look at, standing on the other side. In reflection, the tree appears upside down, but not left to right.

A similar case can be recreated in front of a mirror, without a mirrored ceiling or floor. Just lean your head against the mirror. And put the observer at the bottom. The observer will see that the mirror has reversed the legs and head, but not the arms.

Or let the person lean sideways against the mirror. An observer standing on the side will see the same thing that is used in this riddle: the mirror has reversed the person's hands.

In the case of a mirrored ceiling, a lake, or a person leaning against a mirror, there is a very important difference. Having set the location of the observer, we DO NOT MOVE it. And we can immediately compare both the image and its reflection. And immediately see the axis of symmetry. It will be the line that is formed by the intersection of the planes in which the image of the object and its reflection lie.

Finally, a photo :)

And, although the mirror shows some kind of abstract reflection with which we can compare ourselves as we want (build it along any axis of symmetry), in this reflection we try to see ourselves, first of all, as the same person we saw before, i.e. head up and feet down. The picture in the mirror is distorted, but there is a nuance: the left and right halves of the human body are extremely similar in appearance. And the brain, analyzing, generally speaking, an incomprehensible distorted picture, explains it in the simplest way: you see an ordinary person in the mirror, head up, feet down. That hands have changed, you don’t pay attention to it! The object has already been identified - a person. And only upon closer examination, you notice that his right and left halves have changed places. And then you start to wonder: why exactly did the right and left swap places? But because the choice was already made by you, and before you asked this question. This is how a distinguished horizontal direction arose in our perception. And this, in particular, is manifested in the confusion of horizontal movements, when we control ourselves, guided by the reflection.

But let's try to understand what is wrong, by comparison, like the case with the photographer. We can compare ourselves and the reflection in different ways. Usually a person, "inhabiting" his reflection, rotates around the vertical axis by 180 degrees. Let's simplify: this is the same as a person turning his back to the mirror, standing on the floor, and comparing himself with the original reflection. It turns out that the head and legs have not changed places, but the hands have changed. All the same classic case with a horizontal direction. Now look at the video and imagine that there is a mirror in place of the wall.

The man first stood in front of the mirror, and then stood in a handstand. The original reflection, in comparison with it, had its legs and head swapped, but the hands did not change places! But the techniques are equivalent: turn your back to the mirror, standing on the floor, or stand on your hands, as shown in the video! The angle is the same, 180 degrees. Only the axis of rotation differs. Do you agree? If this action were typical. If you yourself walked on your hands, then on your feet. If you saw other people behaving in the same way, perhaps this mystery would not even arise. He wanted to - turned around, standing on the floor, wanted - stood up on his hands. In the first case, people would notice that the mirror can reflect horizontally, in the second, that it can reflect vertically. Maybe on an inclined axis, people would begin to notice the reflection more easily, having gained freedom of movement in space upside down and at angles.

Everything is explained, as you can see, simply. It's all about rotation around different axes and correct comparison with the original reflection. If you "move" into the reflection around the horizontal axis, then everything changes. As we can see, this way of presenting the riddle is similar to the way of presenting it through a photographer. Only here we turn not the photographer, but ourselves.

So why do we have such a hard time turning around the horizontal or some other axis? And why does such an error even occur when people present a riddle? To summarize all the reasons I found:


  • We live in a space where top and bottom are always rigidly set. We walk mainly in horizontal planes, we turn only to the left to the right; we don’t somersault, we don’t stand on our hands and we don’t walk on them, we don’t fly like astronauts in weightlessness. We find it hard to imagine that we can navigate differently and see the world upside down or at an angle;

  • When we choose how we compare ourselves to the reflection in the mirror, we are based on how we see other people. And we adjust the answer to what our intuition tells us: the head should always be on top. It is difficult for us to imagine another more general answer in order to find a way to solve it;

  • Our right and left sides are very similar, the human body is symmetrical. This also inclines us to the fact that the left and right halves have changed. It is more difficult to imagine, even to assume that the head was in the place of the legs, and the legs were in the place of the head. (Or even on an inclined axis: the right ear and the left heel have swapped places).

Obviously, the reasons are not in the reflection, as in a physical phenomenon, but in our perception.
In the reasoning that describes the perception of a situation, the main mistake usually lies in the fact that people do not specifically specify two positions of the observer and do not try to consider all the ways of moving from one position to another.

Remember, we lay down in front of the mirror and asked ourselves why it still swaps ears, arms, legs. Test yourself - if you understand what is written here, you will find an explanation.
And an exercise that you may like: ask yourself the conclusion that the mirror reflects you along an inclined axis, and try to imagine, explain this to yourself. Either through a virtual photographer and two INDEPENDENT photographs, or by turning your body half a turn around any inclined axis lying in the plane between you and the mirror.

Well, that's the explanation.
It was necessary to completely specify the system: where the image, reflection and observer are located. And it became easier to solve the riddle, to understand what was the incompleteness of the reasoning.

In the case of the inscription "AMBULANCE" the situation is completely different. It cannot be put on a par with this riddle, because the positions of both images and mirrors are already rigidly set in it, i.e. reflection, and the observer.
And based on the fact that the observer is sitting vertically in his car and wants to read the text in the rear-view mirror, as usual, from left to right, the technicians put the inscription on the hood of the car, reflecting the inscription horizontally, from right to left. I must say that they could reflect it vertically, but, when applied, they would rotate it 180 degrees.

We have considered only the case when the person and the mirror are parallel to each other.
And what about the mirror ceiling?

The mirrored floor (the same as the ceiling) you have seen many times. This is a tree and its reflection in the lake, which you look at, standing on the other side. In reflection, the tree appears upside down, but not left to right.

A similar case can be recreated in front of a mirror, without a mirrored ceiling or floor. Just lean your head against the mirror. And put the observer at the bottom. The observer will see that the mirror has reversed the legs and head, but not the arms.

Or let the person lean sideways against the mirror. An observer standing on the side will see the same thing that is used in this riddle: the mirror has reversed the person's hands.

In the case of a mirrored ceiling, a lake, or a person leaning against a mirror, there is a very important difference. Having set the location of the observer, we DO NOT MOVE it. And we can immediately compare both the image and its reflection. And immediately see the axis of symmetry. It will be the line that is formed by the intersection of the planes in which the image of the object and its reflection lie.

Finally, a photo :)
