The world we "see" is a figment of our imagination. Our minds do not generate images in the same way that a video camera does. Instead, the brain builds a model of the world using data from modules that measure light and shade, edges, curvature, and so on. This allows the brain to easily paint out the blind spot, which is the area of your retina where the optic nerve connects and has no sensors. It also compensates for our eyes' rapid, jerky movements, known as saccades, creating the illusion of steady vision.

During the Classical Period, Ancient Sparta was a colossally rich kingdom. Mostly because of their conquest and dominance over a nearby people known as the Helots. When a Spartan boy attained maturity and became a man, the Spartan state bestowed upon him a grant of public farmland. They also sent him a contingent of Helot slaves to work it. This effectively transformed every Spartan citizen into a rich member of the traditional upper class. As a result, they did not have to work for a living. Private property still existed, which is significant because...

Malaysia is home to the world's biggest cave chamber. The Sarawak Chamber at Gunung Mulu National Park is enormous, with enough capacity for 40-50 Boeing 747s. It's another matter if you could actually park these jets in the Sarawak Chamber...

Algeria is the continent's biggest country, spanning more than 2 million square kilometres and borders Mali, Niger, Libya, Tunisia, Morocco, and Mauritania. This places it above Libya, Sudan, and the Democratic Republic of the Congo, and it is about five times the size of Spain.

The lone resident of Monowi, Nebraska, is 83 years old. She is the mayor, librarian, and bartender of the city. Elsie Eiler is her name, she pays her own taxes, and she considers individuals who live 40 miles away to be her neighbours.

An ultra-luxurious lodge has been opened on Nosy Ankao, the biggest of five islands off Madagascar's northeast coast.

Where the Wild Things Are was originally titled Where the Wild Horses Are, and Maurice Sendak intended to write about horses; however, the author and illustrator quickly realised he was terrible at drawing horses and decided it would be better to draw 'things' instead; thus, one of the most memorable children's stories of all time was born.

Despite being surrounded by poverty, wealthy inhabitants of Soroca have turned to flaunting their riches by constructing flashy residences inspired by monuments such as St. Peter's Basilica and the Bolshoi Theatre. As a result, the settlement, called Gypsy Hill, has become something of a tourist attraction, with visitors arriving to marvel at the bizarre buildings.

You definitely wouldn't recognise Greece if someone called it by its official name at first, but that's part of what makes it so fascinating! Hellas or Hellada is how the Greeks refer to their country, and the Hellenic Republic is the official name.

Humans have celebrated the start of each new year with parties, festivals, and religious ceremonies for millennia. However, we haven't always agreed on the beginning of the year. Four thousand years ago, the first new moon after the Vernal Equinox was regarded as the dividing line between the previous year and the new one in ancient Babylon. After Julius Caesar made major changes to the Roman calendar in 45 BCE, January 1 became the start of the new year for the first time. Ancient Romans commemorated the day with sacrifices to Janus, the Roman god of beginnings (after whom the month of January is named), as well as gift exchanges and large parties.

In 2012, when Boeing wanted to test its wireless signal on new planes, they placed massive piles of potatoes on the seats. Potatoes absorb and reflect radio and wireless signals in the same way that humans do due to their high water content and chemical makeup.

Nobody knows for sure where the kites came from. Flying kites is said to have begun around 3000 years ago in China. The first person to fly a kite was Chinese General Han Hsin of the Han Dynasty. Han was actually calculating the distance his army would have to travel to reach the defences.

Texas is where German chocolate cake was invented. The "German" in German chocolate cake is the work of an American man, not a European country. It is named after Sam German, who created the formula for a mild dark baking chocolate bar for Baker's Chocolate Company in 1852, which was later renamed Baker's German's Sweet Chocolate. Let's go back to June 13, 1957. According to What's Cooking America, the Dallas Morning Star published the recipe for the cake, which was invented and submitted by a reader identified as Mrs. George Clay.

The Tonle Sap supports about half of Cambodia's agriculture and is a key fishing source. The incredible thing about this lake is that it regenerates in major areas throughout the rainy season, when monsoon rain pours and floods the centre area between Siem Reap and Phnom Penh.

Under the sea, there are more historic artefacts than in all of the world's museums combined. There are approximately 1,000 shipwrecks off the Florida Keys alone, some of which are protected by the Florida Keys National Marine Sanctuary. Other underwater museums have opened in recent years, including Christ of the Abyss, a submerged bronze statue in the Mediterranean.

This is one of the Japanese facts for children! Because the ice cream will ultimately melt, the term is a little deceptive. It appears that the non-melting ice cream will take several hours to thaw. Consider this, kids: this is unquestionably the finest of the kid's Japan facts! Yummy! The finding happened by chance as scientists were working with strawberry chemistry. This was done to assist farmers affected by the 2011 earthquake.

Shellac is also known as "confectioner's glaze" because it gives candies like jelly beans and candy corn a shiny coating. However, shellac, which is also used as a brush-on colourant and a wood finish, is derived from the excrement secretions of female Kerria lacca insects. In other words, it's bug excrement.

It goes without saying that the ancient Babylonians were excellent mathematicians. They understood the Pythagorean theorem, for example, nearly 4,000 years ago, or more than a millennium before Pythagoras himself was born. Their mathematical prowess naturally extended to astronomy, where they routinely used arithmetic to catalogue celestial body movements and improve their astronomical predictions.

Few odours are as appealing as "new car smell," and it's not just because it's nice to be in a brand new car. However, while the scent may be strangely satisfying, it is actually a combination of 50+ chemicals (known as "volatile organic compounds") that are released into the car and decay quickly over time. The concentrations found in a typical new car are not dangerous, but VOCs found in nail polish, auto fuel, and petroleum contribute significantly to the new car smell.

The most expensive coffee on the planet is "Kopi Luwak." It is made in Indonesia from beans digested by the Asian Palm Civet. That is, it is derived from cat poop. It can cost up to €350 per kilo!

It wasn't Henry Ford's Model T back in 1908. The first vehicle was built in the nineteenth century by European engineers Karl Benz and Emile Levassor who were working on automobile ideas. In 1886, Benz patented the first vehicle.

Just One Letter Long Ten villages in Denmark, Sweden, and Norway have names that are only one letter long. The city name, which means "little brook or river" in the Scandinavian languages, appears nine times in the nations. Sweden has the word, which meaning "island."

Despite the fact that Nazi scientists tried to produce weaponized versions of illnesses such as typhoid and cholera, Hitler banned the employment of offensive biological weapons in war, probably due to his experiences with bioweapons during World War I.

In the United Arab Emirates, the week begins on a Sunday! Sunday in the UAE is just like any other day, with children going to school and adults going to work. Weekends are Friday and Saturday for them. Because Friday is a special religious day in Islam for afternoon prayers, many Middle Eastern countries follow this timetable.
