Ebbinghaus illusion
The Ebbinghaus illusion is an optical illusion where a stimulus appears larger in size than its surroundings. Its appearance depends on its size perception and retinal size. The flash-lag effects, which cause objects to appear similar at later times, confirms that size perception. Participants were shown four identical surroundings disks at different times and relative to their location on the retina in this study. The flash-lag effect occurred when the size of central disks varied from one side to the other.
FAQ
Is there a Hollywood blacklist.
There is a Hollywood blacklist.
The list isn’t available for public viewing. According to our knowledge, the names of these people aren't 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. So they'd go out of business, which means that the studios would lose money. They would also cut back on their spending on movies. This would result in fewer opportunities available for blacklisted filmmakers. Which would lead them to go bankrupt.
This could mean more victims.
If someone attempts to make an Oscar-winning movie, they may be asked to sign a contract stating that they will not speak out against their employers. This applies to any producer or director who wishes to be nominated.
You hear stories of directors being pressured to remove scenes from films. Directors may threaten to quit projects that don’t align with their vision.
This is why there is a Hollywood blacklist. If you are negative about your employer, you'll most likely go unemployed. That's bad for everyone.
Problem is, many people have been falsely charged. They have had to fight for their freedom.
This kind of thing must stop before it can happen again. Everyone should have the right to speak freely.
We must get rid of the Hollywood blacklist.
Ever wonder how much trash gets produced each day around the world?
According to the United Nations the average person creates more than 2.5 lbs of waste daily. That adds up over 25 billion kilos of garbage every year.
Most of this trash ends up in landfill dumps or incinerators.But what happens when those dumpsters get full? The majority of this rubbish is sent 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 name. He is the owner of Waste Watchers. His job involves monitoring the movements and routes of trash trucks across North America. He then reports back about what happens next.
Sexton stated that he finds the job very satisfying. "We've got a lot of fun," he told CNN. "We'll be following these big rigs through town. "Sexton began following truckers almost 20 year ago.
He stated, "I just fell in Love with It."
He loved the story of the driver who pulled into 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. He backed up and entered the building. "There were two enormous roll-off containers filled with stuff. The man got everything out of the truck and began filling it up again. "Then he took out everything and began to fill up the truck. There were tires, rags. furniture, mattresses. boxes, bottles, cans. "It was just a total mess. But it had been cleared out before he arrived. There was no trash."
Why did this happen? It is because the location used to belong to a recycling centre. People who found out about this facility would drive to it to recycle their trash. Sexton explained that they would bring household items and take them to the building. Then, after they were done, they would empty the containers.
This can happen hundreds of times a week. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. The owner eventually abandons 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.
Many of these tiny plastic pieces end up in landfills and incinerators. Others end up in rivers, oceans or the stomachss of fish.
Experts warn of a possible global food crisis if nothing is done. Experts warn that "if we keep going the way we are, we're not going make it," although scientists agree that the world is heading toward disaster. Most people, however, don't seem to be concerned.
What is the most mysterious area on earth?
Antarctica is the world's most mysterious place on Earth.
What is it that makes this place so interesting? Because it is unlike any place on Earth.
It is remote and difficult to reach. It is not what you see.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some believe it means "land of ice." Others believe it derives from Greek mythology.
Antarktis was an ancient Greek name that was given to the island where Zeus and his twin brothers, Zeus. According to some legends, one of these twins was born in winter. Hence, the word antarctic.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would signify land turned away the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the highest, coldest, windiest, dryest, and most populated continent. Because it is so cold, there aren't any trees, plants or animals.
And yet, this frozen wasteland is teeming with life.
Here, 90 percent live of all species of living things. You can find approximately half the world's species of animal and plant plants here.
And what makes Antarctica such a unique environment? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large masses to form of ice which float high above the ground.
These glaciers cover more than 80% of the continent. They are growing in size every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, the sea level will rise by up to 200 feet. That could cause massive flooding around the globe.
But not everyone thinks this is bad news. Some scientists think global warming might be beneficial. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others warn that this theory sounds like something out of a science-fiction movie.
How does your brain control your body's functions?
To ensure that they work together, messages are sent by the brain to other organs. Your brain controls all that happens in your body. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Neurons communicate by sending electrical signals, called action potentials, on axons. Every neuron has a cell wall around its nucleus. There are channels within the membrane that allow ions such a sodium or potassium to enter and exit the cell. The neuron fires when there is ion movement.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. As a result, second neuron fires as well.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. The impulse travels along the synapse connecting the two neurons. The transmitter binds at the receptors of the post-synaptic Neuron and triggers its firing.
The nervous system relies on neurotransmitters for communication. They coordinate brain activity among different parts.
Statistics
- In one 2014 study published in the Archives of Medical Science that sought to study the prevalence of these mites, research showed that 41% of the people had them hanging out in their eyelashes. (romper.com)
- It might not sound like something that's truly plausible — and it is quite rare — but according to a 2015 study published in the Asian Cardiovascular & Thoracic Annals, it's possible to hurt yourself and even break a rib just by sneezing. (romper.com)
- According to a 2018 study published in Free Radical Biology & Medicine, this is because blood pressure is regulated by our innate circadian rhythm and internal clock. (romper.com)
- You spend about 10% of your time awake blinking (romper.com)
- A 2012 paper published in the Proceedings of the National Academy of Sciences reported that people blink about 15 to 20 times each minute, meaning, if you do the math, you spend about 10% of the time that you're awake blinking. (romper.com)

Hollywood scandals that shocked the world
It's shocking to see someone make a name for themselves. However, there is nothing worse than watching them fall from grace.
The best part is seeing how an industry reacts to its mistakes. We have all heard of celebrities who overdosed on drugs and alcohol. Some even died young because of it.
The worst thing is when these stars are made public about their problems and shunned. This is where we ended up last week.
Heath Ledger gave up after a long career that was successful. He succumbed after taking too many prescription medications. After a brief struggle with death, he died.
His family and close friends had difficulty accepting his death. The media took to him publically.
Heath was once regarded as one of the best actors today. Two Academy Awards nominations went to Heath for his performance on Brokeback Mountain.
Heath was not only an actor, but also directed and wrote films like A Knight's Tale and Monster's Ball.
Hollywood loved Heath, but he became too big for his britches. He became addicted to drugs and drank heavily. He eventually went to rehab and was clean.
Now that he was sober, it was time to make amends. He produced a documentary called Room 237 that documented the making process of The Shining. It was supposed that it would be released this year but it won't make its debut in theaters until next.
Heath attempted to get into Hollywood every time. In fact, Heath was twice arrested on drug charges.
We don't believe Heath should have been allowed to go back into the entertainment industry. It would have been nice, however, if he had received some help before things got out of control.
We hope Heath’s story can be an example to other people who believe they can still have it all.
