Ebbinghaus illusion
The Ebbinghaus illusion is an optical illusion that occurs when a stimulus appears larger than the size of its surroundings. Its appearance depends on its size perception and retinal size. The flash-lag effect which causes the objects to look similar later in time confirms size perception. In this study, participants were shown two sets of four identical surrounding disks at different timings relative to their locations on the retina. There was a significant flash-lag effect when the central disks were larger on one side than the other.

What is the most secretive town in the world?
This question might surprise you. It may even make it uncomfortable, as it challenges our perceptions of reality and our lives. But there is an explanation for why this place exists, and it's not what you would expect.
It was called the City of God by ancient Greeks. In the Bible, it was known as the City of Destruction.
It's also known as Kashi (Kashmir) in India. It's also known as Novgorod in Russia.
It's called The Town That Has Disappeared here in America.
One small New York State town with just 1,200 people vanished. No bodies, cars, houses, nothing was left behind except a road sign pointing to its former location.
This little community vanished and no trace remains to indicate where or when it disappeared. Some say it was swallowed up by the Earth. Others claim that a meteorite hit destroyed it. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
Whatever happened, the residents of this once-thriving community are convinced that their town isn't gone forever. They had just moved from one town to the other.
There is even a website dedicated to tracking the disappearance of the lost city of Zugspitz.
You might be wondering where this town went. Well, it's in Switzerland!
Zugspitze is situated on the border between Germany und Austria. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated me that so many towns have disappeared, yet some still remain. Is it possible that some towns disappear and others are preserved? I set out to find out.
I wanted to learn more about mysteriously disappearing towns. What makes a town disappear? What makes a place disappear?
There are several theories behind the disappearing of towns. One theory says that a town disappears when all the buildings are demolished. Another theory is that the town moves to another place. Another theory suggests that the town has never existed.
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.
What is the most interesting fact about the human body?
We have two eyes and two ears, two nostrils each, four limbs, four limbs and a penis. That's right, we have more than 50 parts of our bodies, but one thing is missing. A heart.
A heart is the pump that circulates blood throughout a body. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
Each minute, the heart pumps 5 liters of blood. This amount is equivalent to an adult drinking 2-3 cups of coffee daily.
Blood flows throughout the heart 24 hours per day, 365 Days a Year. While you are sleeping, your heart beats about 100 times per second.
Skin color can be used to determine if someone has a medical condition. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These vessels carry blood away to the heart via the large blood vessels. When blood flow is blocked, the skin turns blue or purple.
People with sickle cell disease lack red blood cells. Patients with sickle cell disease have their blood become sticky and harden, leading to severe illness.
Bandages are used to stop bleeding after you have cut yourself. Blood must continue to flow to allow the wounds to heal properly. Doctors will insert a needle under the skin to access the vein near the injury. This allows the blood from the injured area to drain.
Doctors can also insert catheters into the artery close to the area where the bloodclot has formed. This keeps patients alive until the clot has broken up naturally.
Is there a Hollywood blacklist?
There is a Hollywood blacklist.
The list isn’t available for public viewing. As far as we are aware, the names are not even known. But, here's why it matters.
The reason for the secrecy is that the blacklisted actors and directors wouldn't be able to find jobs. They would go out of business which would mean that studios would lose their money. That would result in a reduction in spending on movies. That would reduce the opportunities for blacklisted filmmakers. This could lead to them going bankrupt.
This could lead to more victims.
When someone tries making an Oscar winning movie they might be asked for a contract. This means that they can't publicly criticize their employer. Producers and directors who want to be nominated are subject to the same restrictions.
It's no surprise that directors are often forced to take out scenes in their films by producers. Directors threaten to abandon projects that don’t conform to their vision.
This is the reason there is a Hollywood blacklist. If you speak negatively about your employer, you will likely be fired. This is bad news for anyone.
There are many people who have been falsely accused. They've had the toil to clear their name.
This is unacceptable behavior and must be stopped. Everyone should have the right to speak freely.
We must get rid of the Hollywood blacklist.

Secret societies and clubs in American history
The secret societies and clubs in American History are fascinating for many reasons. Their mystery is just one reason. Another reason is their influence on our society.
Secret societies and clubs have been used throughout America's history to promote ideas that would otherwise be considered taboo. Anti-Semitism is one example of such ideas. These groups also promoted political ideologies such communism, socialism, and other socialist ideas.
The Ku Klux Klan is America's most well-known organization. This group was formed after the Civil War ended in 1865. Its purpose is to protect white people from African Americans.
The Knights Templar and Freemasons were also created during this time. All of these groups shared similar beliefs and goals.
Another interesting aspect of secret society membership is that it was not only for males. However, these groups had some female members. These women were Emma Goldman and Margaret Sanger as well as Susan B Anthony.
There were other secret societies that did not share these ideals, in addition to those mentioned. The Order of Skull & Bones for instance was founded in 1832. Their goal: to create an elite American class.
