In today’s article, I have collected seven amazing illusions that will probably blow your mind.
Some seem simply unbelievable and impossible, but science says otherwise.
Illusion #1: Girl – monster or beauty?
Set a timer for 15 seconds and keep your eyes on the spot on the tip of her nose. When the time is up, turn your gaze to an empty white area on the right. Then you will see the colorful face of a beautiful young girl!
If we look at a certain color for a long time, we stimulate the cells sensitive to that color. When we shift our gaze to a neutral background, the opposite effect occurs – the cells’ activity suddenly decreases and we see the opposite color.
Illusion #2: Overlapping squares. Or not?
At first glance, it seems clear that the circles made of squares overlap. But this is not so. What would happen if we connected the squares with a pencil?
No overlap! Here is a similar illusion with lines. The colors are selected as if the lines are unevenly spaced. But take a ruler and measure that they are actually perfectly straight!
Illusion #3: Motion that doesn’t exist.
You might think these are GIF images. The lemons move, the gears spin, and the star shakes. But these are just drawings! So why does our brain see them moving?
Be careful while looking at these pictures. They can easily cause dizziness.
The different colored spots, which are placed in a special way, do not trigger neural reactions in the cortex of the cerebrum, but in sequence. This is how the illusion of non-existent movement is created.
Illusion #4: The color that doesn’t exist!
These examples focus on color illusions. Here is a drawing with balls. The balls appear to be different colors. But not! All balls are the same color.
And this photo is black and white. But because of the drawn lines, our brain assigns different colors to objects. For example, I see the girl’s sweater as blue. But someone else sees a completely different color!
Remember when everyone was crazy about the color of this dress a few years ago? Some people saw a white and gold dress, and others black and blue. How is this possible? you can ask. The actual color of this dress can be seen in the middle of the picture!
Illusion #5: Ames Room Illusion.
This illusion was invented by ophthalmologist Albert Ames. The secret is that the room is actually not rectangular, but trapezoidal. But because of the squares, we perceive the room as rectangular. Squares aren’t squares anyway
