Usually people always say "seeing is believing", but recently a treasure blogger @jagarikin told us:
seeing is not necessarily believing, and the eyes are also very "fools." The reason
said this is because he created a series of optical illusions with a wide open brain, each of which can easily make your eyes lie to your brain.
Today we will take a look at one of the very interesting categories.
One
These squares will "play in place"!
never heard of it? Feel strange? It doesn't matter, please look at the picture below and listen to the question:
, look at these two cubes, have they turned? Image source of

Nearly 60,000 Twitter netizens saw this picture posted by @jagarikin on Valentine's Day.
Their first reaction is that the cube is spinning.
but actually? You must have guessed the answer: didn't move at all. Many students of
will definitely find it incredible. They clearly tell us that these two cubes are moving...
But as long as you put your finger on any fixed position on the cube as a reference, and then look at it, you will know that they are indeed not. move.

"like moving" optical illusion
"lie" from the eyes
If you say that an eye error is only accidental, then the following pictures will definitely make your eyes suspicious.
Here is another picture of the theme of the Tokyo Olympics. Do you think that Tokyo (Tokyo) and 2021 are running on both sides, the more they are separated?

Obviously, with the following Olympic rings as a reference and the previous experience of being deceived, your eyes will think about it before lying-
Tokyo (Tokyo) and 2021 have not moved.

If you see baby0zzzzz3, every curious zzz
will ask here. 3. What are these optical illusions
The pictures that fool the eyes in front actually reflect a psychology/neuroscience concept: Phi Phenomenon.
The picture below is a simple and clear quasi-movement phenomenon-each yellow dot has not moved at all. It just depends on the light and dark changes to make us feel the movement. Image source of

The magical little mouse in front is similar. The main body of the image is not moving, which makes people feel the movement. It is the edge and background of the light and dark changes. As long as
controls the order of the edges from dark to light, so that the contrast between foreground and background is strong enough, people will feel that the objects in the middle are moving. The optical illusion of

The phenomenon of movement was first published by Max Wertheimer (Max Wertheimer) in the document "Experimental Studies" published more than one hundred years ago (1912) on the Seeing of Motion, but it was not clear why. Later research by
revealed more about the principle that the human eye judges stillness as motion. For example, video (movie) is actually more than 20 frames per second.The moving picture , the reason why people feel that the image is moving is that the human optic nerve has a limit to its response speed, which can only respond to changes in light at a speed of about 10 Hz per second. When the speed of change reaches about twice, the static image Although there is no real movement, it is considered by the brain to be in a state of movement.

optical illusions
are all made by our brains
However, why can the light and shade changes deceive the eyes? Why does more than twice produce a feeling of movement? Why are there so many optical illusions?
, in the final analysis, is that the human visual system is too complicated, and no one can understand the deepest reason. However, there is currently an explanation that is easier to understand. The simple summary is the theory of "the brain is prone to errors because the brain is often filled".
All objects in the world are three-dimensional, but retinal imaging is two-dimensional. The moment the three-dimensional information is reflected on the retina through light, it is flattened and simplified. It’s okay if you don’t understand
, it’s okay to feel how complicated it is.

and our final vision is almost all three-dimensional, which means that the nervous system must translate the two-dimensional signals "passed" by the eyes. , Processing, and even "tampering" , and this process is affectionately referred to by many people...
brain supplement.
Yes, what you see is actually what you came up with.
When the three-dimensional information is "photographed" by the eyes into a two-dimensional picture, a three-dimensional image of the brain can only be relied on "brain supplement". The large number of optical illusions of
are based on the needs of the human brain to automatically fill in missing information. This also means that as long as you master some skills, the eyes want to "deceive" you only in minutes.
But then again, although the optical illusion is a fool of our eyes, after reading it, not only will we not feel uncomfortable, but also an inexplicable pleasure.
In addition to the illusion of movement, the eyes also deceive you a lot. It just happens that today is April Fool's Day. Why don't you just... let the eyes make you happy for a while?
