Ebbinghaus illusion
The Ebbinghaus illusion, an optical illusion, occurs when a stimulus appears bigger than its surroundings. Its appearance depends on its size perception and retinal size. The flash-lag effect confirms the size perception, which causes objects to appear identical at a later date. Participants were shown four identical surroundings disks at different times and relative to their location on the retina in this study. It was evident that the size of the central discs on one side of the retina changed significantly, creating a flash-lag effect.
FAQ
What is the most secretive town in the world?
This question might surprise you. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. However, there's a reason for this place to exist. It's not what we would expect.
The ancient Greeks called it the City of God. It was also called the City of Destruction in the Bible.
It is also called Kashi in India (Kashmir). It is also called Novgorod in Russia.
Here in America, however, it is called The Village That Disappeared.
One small New York State town with just 1,200 people vanished. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
This tiny town vanished without any trace. Some believe the earth swallowed them up. Others claim a meteorite strike destroyed it. Others claim it was taken away by aliens.
The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They had just moved to another town.
There is even a website dedicated to tracking the disappearance of the lost city of Zugspitz.
So where is this town? It's in Switzerland.
The border of Austria and Germany is at Zugspitze. Lake Zugspitze can be found just beyond the summit.

I wanted to learn more about mysteriously disappearing towns. What causes a town to disappear? How can one place become extinct?
There are many theories to explain the phenomenon of disappearing towns. One theory says that a town disappears when all the buildings are demolished. Another theory is that the town moves to another place. A third theory claims that the town never existed at all.
The fact is that hundreds of towns all over the world have been swept away by the ground, despite theories to the contrary. This video examines the past and present status of these areas.
Ever wonder how much trash gets produced each day around the world?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
The majority of this garbage ends up in incinerators or landfills. But what happens when the dumpsters become full? Most of that trash is shipped out of the country. The rest is dumped abroad, where it pollutes other ecosystems. Now, we know the exact location of all this garbage. Mike Sexton is his full name. He is the founder of Waste Watchers. He watches over trucks that transport trash across North America. He reports back to us about the next steps.
Sexton said he enjoys his job. "We've got a lot of fun," he told CNN. "You know, we see these big rigs come through town, and we'll follow them. "Sexton began to follow truck drivers around 20 years ago.
He stated, "I just fell in Love with It."
His favorite story involved a driver who pulled off at an abandoned gas station near Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He saw the building as he drove down the road. So he backed up and went inside. "There were two large roll-off containers full of stuff. The man removed everything from the truck and started to load it again. "Then he looked at the place and decided to unload everything. There were old tires and rags, furniture pieces, mattresses, mattresses and boxes. It was a complete mess. But it had been cleared out before he arrived. There was no trash."
This is the reason why it happened. It's because this area used to be a recycle center. People would drive from all over the country to recycle their trash. Sexton explained that people would bring home their household items, and then take them to the building. After they were done, they would dispose of the empty containers.
This could happen hundreds of time per week. This could happen hundreds times per week. Finally, the truck stops running completely due to its excessive junk. The truck eventually stops running and the owner decides that it is time to get rid of the vehicle.
But, this isn't the only problem that our planet is facing.
Plastic pieces make up most of these particles. Some are washed into rivers and oceans. Others end up with fish in their stomachs.
Experts warn us that we may soon face an international food shortage if things don't change. Experts warn, "If you keep going like you're going," we could soon face a global food shortage. But most people don't seem to be worried, even though scientists are unanimous in warning us that the world is heading towards disaster.
What is the most fascinating fact about the human body
Two eyes, two ears and two nostrils are part of our bodies. We also have four limbs: a mouth, nose, penis, and four limbs. It's true, we have more 50 parts of our body, but there is one thing missing. A heart.
A heart is the pump that circulates blood throughout a body. Blood travels through the arteries and veins, carrying oxygen and nutrients to the cells and removing carbon dioxide and waste products.
The heart pumps about 5 liters blood per minute. This is equivalent in daily coffee consumption to an adult who consumes approximately 2 to 3 cups.
The blood flows throughout the heart 24/7, 365 days a calendar. When you're asleep, your heart beats approximately 100 times per hour.
The color of someone's skin can tell if they are healthy or not. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These small vessels carry blood away from the large blood vessels in the skin back to the heart. If blood flow is blocked, skin can turn blue or purple.
Red blood cells are not available to sickle cell patients. Their blood becomes sticky and hardens, causing them to become very ill.
You can use a bandage to stop bleeding if your cut is severe. For the wound to heal properly, blood must continue to flow. Doctors will insert a needle under the skin to access the vein near the injury. This allows the blood to drain from the injured area.
Doctors also insert tubes (catheters) into the artery near the site where the blood clot forms. This keeps the patient occupied until the clot is broken down naturally.
