Ebbinghaus illusion
The Ebbinghaus illusion, an optical illusion, occurs when a stimulus appears bigger than its surroundings. It depends on how the stimulus is perceived to be larger than the surrounding objects. The flashlag effect, which makes the objects appear similar at a later point in time, supports the size perception. Participants were presented with four sets of identical surround disks at different times relative to their positions on the retina. When the central disks' sizes changed from one side of a retina, a significant flash-lag effect was observed.

Which is the most secretive city in the world?
It may surprise you to hear the answer. This may make you feel uncomfortable as it challenges your perception of reality and the way we live. 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. In the Bible, it was known as the City of Destruction.
It is also called Kashi in India (Kashmir). It's known in Russia as Novgorod.
However, in America it is called The Town that Disappeared.
One small New York State town with just 1,200 people vanished. There were no bodies, cars or houses left behind, but a road sign that pointed to the former location was all that was left.
This tiny community disappeared without leaving any clues as to where it went or when. Some believe it was swallowed by the earth. Others claim that a meteorite hit destroyed it. Some believe that it was taken by aliens.
Regardless of what happened, residents of this once-thriving town are certain that their town won't be forgotten 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.
So, where exactly did this town go? It's in Switzerland.
The border of Austria and Germany is at Zugspitze. Lake Zugspitze can be found just beyond the summit.
It has always fascinated my that so many towns have disappeared but others still exist. Why is it that some disappear while others live on? I decided to investigate.
I was interested in learning more about these mysterious towns that are disappearing. What makes a town disappear? How does one place go extinct?
There are many theories to explain the phenomenon of disappearing towns. One theory holds that a town disappears if all its buildings are demolished. Another theory suggests that the town simply moves somewhere else. The third theory is that the town was never actually there.
There are many theories, but the truth is that thousands of towns around the world have been submerged by the earth. This video looks into the history of those places and investigates their current status.
What is the most surprising fact about your body?
There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. We have over 50 parts of our bodies. However, one thing is missing. A heart.
A heart is a pump, which circulates blood throughout our bodies. 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 is equivalent to a person drinking 2-3 cups 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.
Because of the color and texture of their skin, you can tell if someone is healthy or sick. If you examine the skin closely, you will 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.
People suffering from sickle cell disease have no 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 insert a needle into the injured area through the skin. This allows blood to drain from the area.
The doctor may also insert catheters (catheters), into the artery at the site of the blood clot. This keeps the patient occupied until the clot is broken down naturally.
Is there a Hollywood blacklist.
There is a Hollywood blacklist.
The list isn’t available for public viewing. The names are not known to us. 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. So they'd go out of business, which means that the studios would lose money. That would result in a reduction in spending on movies. This would lead to fewer opportunities and less money for blacklisted directors. They could go bankrupt.
Which could ultimately result in more victims.
In other words, if someone is trying to make an Oscar winning movie, they might have to sign a contract that says they won't speak openly against their employers. The same goes for any director or producer who wants to get nominated for an award.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Directors threaten to abandon projects that don’t conform to their vision.
This is why Hollywood has created a blacklist. If you speak negatively about your employer, you will likely be fired. This is not good news for anyone.
Many people have been wrongly accused. These people have had to fight to clear their names.
We need to stop this kind of thing before it starts happening again. We must ensure that everyone has the right to express themselves freely.
We need to get rid of Hollywood's blacklist.

American history's secret societies and clubs
Many reasons make American History's secret societies and clubs fascinating. The mystery surrounding them is one reason. Their impact on our society is another reason.
Secret societies and clubs have been used throughout America’s history to spread ideas that would otherwise be taboo. Anti-Semitism, racism, and other ideas are just a few of the many examples. These groups also promoted political ideologies such communism, socialism, and other socialist ideas.
The Ku Klux Klan is the most prominent American organization. This group was created in 1865 after the Civil War. Its purpose is to protect white people from African Americans.
Other organizations established during this period were the Knights Templars and Freemasons. These groups had the same goals and beliefs.
Another interesting aspect about secret societies is their ability to restrict memberships to men only. These groups also had women members. These women included Emma Goldman (Margaret Sanger) and Susan B Anthony.
Not only the above mentioned groups, but also other secret societies didn't share the same ideals. The Order of Skull & Bones for instance was founded in 1832. Their goal was to create an elite group within the United States.
