Ebbinghaus illusion
The Ebbinghaus illusion is an optical illusion where a stimulus appears larger in size than its surroundings. Its appearance depends on the perceived size of the surrounding objects and the retinal size of the stimulus. The flash-lag effect which causes the objects to look similar later in time confirms 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.
FAQ
Ever wonder how much trash gets produced each day around the world?
The United Nations states that an average person produces more than 2.5 pounds of waste per day. That's over 25 billion pounds of garbage each year!
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? 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 nickname. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He reports back to us about the next steps.
Sexton claims he is very satisfied with his job. CNN asked Sexton if he thought it was a lot of fun. "We often see large rigs passing through our town and we will follow them. "Sexton started following truck driver almost 20 years back.
He stated, "I just fell in Love with It."
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton remembered, "The man was looking for somewhere to put the load." "He drove along the road and saw this structure. He stopped and pulled up, then he went inside. "There were 2 large containers that had been rolled off, and they were full of stuff. He took out everything and began to fill up the truck. "Then he took out everything and began to fill up the truck. There were many old tires, furniture, rags and mattresses. "It was a complete mess. But it had been cleared out before he arrived. There wasn't any trash."
So why did this happen? This particular spot used to be a recycling center. People would drive there to recycle their trash. "They'd bring their household items and take them to this building," Sexton explained.And after they finished, they would leave the empty containers behind.
You might see this happen hundreds of times a day. This can happen hundreds of times a week.Eventually, the truck becomes so overloaded with junk that it stops running. And eventually, the owner decides to abandon the vehicle.
Trash, however, isn't the only problem facing our planet.As you may have noticed, things are getting worse.According to experts, pollution levels have risen dramatically in recent years.More than half of all water bodies on Earth are polluted.Pollution from industrial chemicals has increased by more than 30 percent since 1980.Even the air we breathe is becoming increasingly toxic.A study by the World Health Organization found that the average person inhales around 100 million particles daily.
The majority of these particles are made of small pieces of plastic. Others get washed into rivers or oceans.And when they reach the ocean, they often end up in the stomachs of fish.
Experts warn that if there is no change, the world could soon be facing a food shortage. "If we keep going like we're going, we're not going to make it," one expert warned.But even though scientists agree that the world is headed toward disaster, most people don't seem worried.
What is the most mysterious place on earth?
Antarctica is the world's most mysterious place on Earth.
What is it that makes this place so interesting? Because it's unlike any other place in the world.
It is difficult to access because it is remote and extremely isolated. There is much more to this place than meets the eyes.
You'll also find the strangest species of wildlife in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it refers to "land of ice". Others believe it comes out of Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to one source, one of the twins was conceived in winter. This is why the word "antarctic" was chosen.
Others believe that the name is a combination of the Greek words anti and tropos which mean against and turn. This would mean land turned away from the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the driest, windiest of all continents. Because it is too frigid, there are no trees, animals, or plants.
Yet, the frozen desert is alive with life.
It houses approximately 90% of all Earth's living organisms. Here are approximately 50% of all the animal and plant species in the world.
What makes Antarctica so special? Here water freezes to ice and not evaporates into the atmosphere.
This causes large masses to form of ice which float high above the ground.
These floating glaciers cover 80% of the continent. These glaciers are getting larger each year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead to massive flooding across the globe.
This is not necessarily bad news. Global warming may be beneficial for some scientists. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
What is the most secretive place in the world, and why?
The answer to that question may shock you. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. But there is a reason why this place exists. And it is not what you would expect.
The City of God was its name by the ancient Greeks. It was also called the City of Destruction in the Bible.
It's known in India as Kashi (Kashmir). In Russia, it's called Novgorod.
However, in America it is called The Town that Disappeared.
One small community in western New York State with 1,200 residents vanished without a trace. A road sign pointing to the former location of the town was all that was left, except for a few bodies and cars.
This little town disappeared, leaving no clues about where it went or when. Some say the earth swallowed it up. Others claim a meteorite strike destroyed it. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
Despite what may have happened, the people who lived in this once-thriving area are confident that their town will not be lost forever. They had just moved to a new town.
There is even a website dedicated to tracking the disappearance of the lost city of Zugspitz.
The question is, where did this place go? It's in Switzerland.
The border of Austria and Germany is at Zugspitze. Lake Zugspitze lies just above the summit of the mountain.
I have always been fascinated by the fact that so many towns have vanished, but some remain. Why do some disappear while others survive? I decided to investigate.
I was curious about the disappearing towns. What is the secret to a town's disappearance? How can a town disappear from existence?
There are several theories behind the disappearing of towns. One theory suggests that a community disappears when all of its buildings are removed. Another theory states that the town simply moves to another location. A third theory states that the town didn't exist at all.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video looks into the history of those places and investigates their current status.
Why are actors blacklisted?
An actor is more likely to get rejected than a writer. If you're an actor, you'll probably get rejected a lot. You will find someone who loves and accepts you eventually.
Actors can often make a living from acting because they are very talented. Most actors don't care about making money. Actors love acting, and love telling stories. You'll be an actor if you love acting.
Sometimes you may be told by the audition panel that you are too young, too old, or wrong for the role. Or you might audition for a movie and lose out to another person. It happens all too often.
You may be criticised once your casting is complete. People may tell you that your makeup looks terrible and you shouldn't use it. If you're lucky, you won't even hear negative comments.
Sometimes your character isn't real or authentic and you will be criticised. Perhaps you play a homosexual man and everyone thinks that you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Sometimes they might ask you to change how you speak. Sometimes they ask you to sound like a guy or a girl. Most of the time, however, they want to hear better.
The best way to deal with these criticisms is to ignore them. Actors often feel like they've failed if they're told they did something wrong. But they're not guilty of anything.
They didn't have the talent to make them famous. They may not fit the bill sometimes, no mater how hard they try.
Blacklisting can happen for many reasons. Some people don't like actors. Others think that actors are lazy. Others think actors are lazy.
No matter the reason, it is important to remember that you will not be blacklisted if there are other jobs available. There are plenty of roles out there, and you'll find them.
If you persevere, you will eventually succeed.
