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 flashlag effect, which makes the objects appear similar at a later point in time, supports the size perception. Participants were shown two sets each of four identical surrounding discs at different times, depending on their position on the retina. A significant flash-lag effect was observed when the size of the central disks changed from one side of the retina to the other.
FAQ
Which is the most mysterious spot on Earth?
Antarctica is the world's most mysterious place on Earth.
Why do we find this place so intriguing? It is unlike any other place on Earth.
It is isolated, remote, and very hard to visit. But there is more to this site than meets the eye.
These wild animals are also found in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Some say it means "land on 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 one source, one of the twins was conceived in winter. Thus, the term antarctic.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would translate to land that is turned away from the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the driest, windiest of all continents. It is too cold for trees, plants and animals.
Yet, life is abundant in this frozen wilderness.
It is home to approximately 90 percent of all life on Earth. There are about 50% of the world's animal, plant and plant species.
What is it that makes Antarctica so unique? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large ice masses to rise above the ground.
These glaciers are responsible for covering 80% of the continent. They continue to grow in size each year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
If the melting continues, sea level could rise up to 200ft. This could lead to widespread flooding.
This does not mean that everyone is wrong. Some scientists believe that global warming can be beneficial. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
Is there any Hollywood blacklist for actors?
There is a Hollywood blacklist.
But, the list has not been made public. The names are not known to us. This is why it matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. They would go out of business which would mean that studios would lose their money. It would mean they would reduce their expenditure on movies. That would reduce the opportunities for blacklisted filmmakers. They would then go bankrupt.
This could result in even 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. The same goes for any director or producer who wants to get nominated for an award.
It's no surprise that directors are often forced to take out scenes in their films by producers. Or how directors threaten to walk away from projects that don't fit their vision.
This is why Hollywood has a blacklist. If you make negative comments about your employer, it's likely that you will be unemployed. And that's not good for anyone.
It is not uncommon for people to be falsely accused. They have had to fight for their freedom.
This is unacceptable behavior and must be stopped. Everyone should have the right to speak freely.
Also, we must take down the Hollywood blacklist.
How does your brain control the functions within your body?
The brain sends messages to other organs and muscles to ensure they work together. Your brain controls all that happens in your body. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made of billions, or neurons, of nerve cells. Action potentials on Axons are an electrical signal that neurons send to each other. Each neuron has its own cell membrane around its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. The neuron fires when there is ion movement.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. In turn, the second neuron also fires.
Neurotransmitter release occurs when the presynaptic neuron receives an impulse from another neuron. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
For communication within the nervous systems, neurotransmitters are essential. They also help coordinate activity between different parts of the brain.
What dark secrets do Hollywood have?
Hollywood is full secret societies. There are secret societies that are more cult-like than others. They have members who follow specific rules and rituals. While some are clubs for those with similar interests, others are not.
There are also other, more evil organizations that control large parts of the industry. These include the MPAA (Motion Picture Association of America), the organization that sets film ratings and RIAA(Recording Industry Association of America), the company that sets music licensing fees.
Numerous unions/guilds also represent actors and directors as well as writers, producers, and so forth. The majority of major television networks and movie studios are owned by large corporations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. However, we shouldn't fear them.
Instead, embrace them. Because they offer us information that can help us make better decision.
These people tell us what movies and songs will succeed, and which books will sell best.
They allow us to make informed decisions about what we buy, watch and listen to.
We can trust them so we can ignore their advice when it doesn't suit our taste.
And because we've chosen to ignore them, they become even more powerful. They are the ultimate judges of taste.
And if you don't like what they say, you're free to ignore them.
Let's now take a look into some lesser-known but very real Hollywood secret societies.
And see why they're so important.

- You spend about 10% of your time awake blinking (romper.com)
- The average human adult male heart rate is between 70 and 72 beats per minute, while the average for adult women is between 78 and 82 beats, which is significantly faster, according to 2014 published in the Journal of Clinical and Diagnostic Research. (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)
- 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 globe
Nothing is more shocking than seeing someone famous for wrong reasons. But there's also nothing worse than seeing them fall from grace.
It's fascinating to see how industries react to their mistakes. Many celebrities have used alcohol and drugs in excess. Some even died young because of it.
The worst part about this is that these same stars come out with their problems and are ridiculed by everyone. 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 friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once considered to be one of today's most talented actors. Two Academy Awards nominations were given to Heath for his role in Brokeback Mountain.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
Hollywood loved Heath but he grew too large for his boots. He started taking drugs and drinking heavily. He ended up in rehab and became clean.
He wanted to make amends now that he was sober. He created a documentary called Room 237, which documented the making of The Shining. It was supposed to hit theaters this year. However, it won't until next year.
Heath tried many times to get back into Hollywood. Nothing worked. In fact, Heath was twice arrested on drug charges.
We're not saying Heath should have been allowed back into show business. However, it would be nice if he could get some help before things spiral out of control.
We hope Heath's story warns others who might think they can still have it all.
