Unexpected optical illusion

Recently, distinguished professor Sugihara, a Japanese optical illusion master and Meiji University? Magic arrow? Works and attracted the attention of people all over the world:

To quote Professor Sugihara's classic description: The way we look at the outside world, that is, our perception is indirectly generated by brain mechanisms, so all perceptions are illusory to some extent. The study of illusion is the key to our understanding of sensory perception and many ophthalmic and nervous system diseases. ?

He also has such works:

Optical illusion, also known as optical illusion. Generally speaking, when an object passes through a very regular geometric arrangement, it is easy to have an illusion. Plus the human brain, are you used to it? Brain tonic? So sometimes, what you see with your own eyes is just a kind of deception.

This is the interesting thing about illusion. By understanding it, we can learn more about people's sensory functions, and we are interested in it. Explore the truth of things? Change the angle.

Never trust your eyes too much.

Ten illusion diagrams

1, Panlotti, impossible figure

Pan Luo ladder is an impossible figure, also known as? Endless stairs? . Ordinary human flesh can't see the difference. A floor plan is an ordinary photo. If you look at it from a three-dimensional perspective, you will find the magic of the Panlos ladder. From the above picture, we can see that there are four upward stairs, all of which extend to each other, giving you a visual illusion. It looks like a wireless loop ladder, so that you will never reach the finish line. ......

2. The devil's tuning fork

See the picture above? Do you think it is incredible? This is also an impossible number called. The devil's tuning fork? . The top looks like two rectangular cuboids, but from the bottom it becomes three cylinders. I feel that my eyes are not enough. Is the whole corner rectangular or cylindrical? I don't know, either.

3. Impossible cube

You notice two of the edges. When you look at one of them, you find that the other one is far away. When you look at the edge of the whole change, you will find that the previous edge has become farther away, giving people a visual illusion. This kind of graph is impossible to exist objectively in the real world, so it is also called impossible figure.

4. Impossible triangle

It seems reasonable to look at a single angle with our naked eyes, but when you look at it as a whole, you will find that the problem is that all three sides of a triangle are perpendicular to 90 degrees, which obviously does not exist and cannot be realized. Because it is impossible to connect them, all because of visual errors.

5. Crazy nuts

Do you know how the straight steel bar magically passes through these two seemingly right-angled nut holes? The two nuts are actually hollow, although they look convex, so they are not perpendicular to each other. Nuts are illuminated by the light source below (generally light should come from above), which gives people wrong information to judge their true three-dimensional shape. In American magic? Andrews created this wonderful illusion.

6. impossible chessboard

This chessboard is completely flat. This chessboard is based on Swedish artist Oscar? One of Reuters Sward's designs is based on Bruno? Western creation. I think it can be seen from the above picture that this impossible chessboard is a contradiction space, which is impossible in reality and can only appear on a plane.

7. Impossible birdcage

The impossible birdcage is an impossible birdcage created by Flemish artist Jones de May for these parrots. First of all, this birdcage is just like the impossible cube mentioned above, which is impossible to realize in reality!

8. the impossible door

The impossible door is a typical optical illusion picture. If you look at the upper door beam, you will find that the problem is not serious, but if you look at the lower pillar, it is obvious that this pillar is not in line with the other two.

9. Upstairs and downstairs

Looking at the picture, do you feel like you are on a plane? But when you look from top to bottom, you find one upstairs and one downstairs. I really don't understand.

10, impossible shelf

There are many balls on the shelf, but did you find the problem? The three balls in the lower layer are not on the same level at all.
