When you think about Greece, you probably see sandy beaches, turquoise seas, whitewashed houses, and blue domes. However, one of the most unexpected facts about Greece is that the bulk of the nation is really made up of mountains. It is one of the most mountainous nations in Europe, with mountains covering 80 percent of the land area. Remember to bring a decent pair of walking shoes!

Sechs Kies is South Korea's most established idol group. The band was founded in 1997 with six members and currently has five active members. Some may not consider them the longest because they were on hiatus for more than ten years; however, the longest-lasting idol group could also be considered Shinhwa, who debuted in 1998 and has been promoting consistently for the past 20 years.

Though it was not the first film ever made, "The Great Train Robbery" (1903) was the first to tell a story and is widely regarded as the first narrative fiction film. It was produced by Thomas Edison's Edison Studios and was only about 12 minutes long. The filming took place in New Jersey. 

The most impressive artificial paradise, with a length of 1,000 yards, an area of 20 acres, and a maximum depth of 115 feet, can be found in Algarrobo city on the Pacific coast. It was named by the Guinness Book of Records as the World's largest swimming pool, with a length of 1,000 yards, an area of 20 acres, and a maximum depth of 115 feet. It can contain nearly 66 million gallons of crystal clean saltwater. The pool opened in December 2006 after five years of building work at a cost of about one billion dollars ($US) and an annual maintenance cost of roughly two million.

If you go to Moldova for a vacation, you won't have to compete for space with other tourists: just 121,000 foreigners are believed to have entered the nation in 2016 (according to the UN World Tourism Organization), making it the least visited country in Europe. According to Priceonomics, only Bangladesh and Guinea are less touristic places on a worldwide scale (in terms of tourists per inhabitant).

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.

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.

An ultra-luxurious lodge has been opened on Nosy Ankao, the biggest of five islands off Madagascar's northeast coast. Miavana (only accessible by helicopter) is a destination for "blue safaris," which include opportunities to see turtles, whales, and dolphins, as well as scuba diving and fishing. There's also a fantastic spa. But start saving now - doubles start at £3,220 per night.

Fischer was charged in 1992 with violating economic sanctions imposed on Yugoslavia. He came out of retirement to earn $5 million in a rematch against his old nemesis, Boris Spassky. Fischer never returned to the United States and eventually settled (and died) in Reykjavik after renunciating his American citizenship.

In the year 1,000 AD, half a millennium before Christopher Columbus "discovered" America, Greenlandic Viking chief Leif Eriksson arrived on the island of Newfoundland. Leif Eriksson's Vikings inhabited Newfoundland, as well as finding and populating Labrador further north in Canada.

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.

Christian Dior technically invented designer sunglasses when, in the early 1960s, they licenced their brand to be used to produce luxury sunglasses for discerning fashionistas. Using Optyl, his own lightweight thermo-hardening material, he converted expensive sunglasses into more wearable everyday items. The properties of this material also allowed for a wider choice of models, from broad and original lines to previously discovered hues and delicate degradé of translucent, brown, green, and grey colours that still mark Dior's beautiful and refined style.

Did you realise that the word "Pennsylvania" is misspelt on the Liberty Bell? Actually, worded incorrectly is perhaps a bit harsh: when the bell was constructed in 1752, it was one of several permissible spellings. The ancestors of the United States also committed several obvious language errors in the Constitution.

King Idris I was the first and last ruler of Libya. Born into the Senussi order, he was both a political and religious leader. Before becoming King of Libya in 1951 with the end of colonial control, King Idris I served as the Emir of Cyrenaica. Because of his conservatism, the king's rule was unpopular. Colonel Gaddafi, who eventually replaced King Idris I, was toppled in a coup orchestrated by Colonel Gaddafi in 1969.

Egypt's ancient pyramids were built during an 85-year period, between 2589 and 2504 BC. The Sagrada Familia, Antoni Gaudi's masterwork, began building in 1882 and has continued under development ever since. Gaudi was never able to see his masterpiece completed. After 144 years of development, Barcelona hopes to have it finished by 2026, the 100th anniversary of Gaudi's death.

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.

The Nazis pondered releasing an army of potato bugs on their adversaries, which they felt might be dumped on England to ruin its crops and bring severe starvation. However, experts recognised that almost 40 million insects would be required for the operation if it was to be successful—though several million had been hoarded by the time the war ended.

Something frowned upon in most other nations is quite acceptable in China. In China, spitting, yawning, grunting, and burping is normal eating behaviours, just as they are in Vietnam. It was repulsive to us, and we couldn't get used to it. We would bear it better if we stayed in this nation for a little longer.

Muammar Gaddafi took power in Libya in 1969 and reigned for 42 years. As a result, he became one of Africa's and the world's longest-serving leaders of state. Gaddafi was well-known for being a despotic ruler. He did, however, serve his country well by increasing health care to the point that it was among the finest in Africa. He also boosted Libya's literacy rate from 25 percent to 87 percent during his tenure. When he was removed from power in 2011, his reign came to an end. The militia hunted him down and murdered him in his hometown, where he had sought safety. Gaddafi's net worth was $200 billion at the time of his death.

During the feudal period, rich Japanese lords constructed residences with purposefully squeaky flooring (known as Nightingale Floors) to deter ninjas. The fabled, highly trained mercenaries of mediaeval Japan were so entrenched in myth and tradition that they were thought to be capable of walking on water, becoming invisible, and controlling natural forces. That has to be enough reason to lay down some new flooring.

It is frequently debated among professionals which era is regarded as the "best" in modern game history. Chess, like modern sports, has gone through several eras in which the perspective of how the players competed changed. For example, in chess, the Romantical approach favoured quick tactical moves over long-term strategy. When players changed their playing styles, valuing one thing over another, new "ages" of chess would emerge.

Angkor Wat is more than simply a famous structure or a historical site; it is Cambodia's heart and soul. The world heritage-listed structure, which was erected in the early 12th century, is the world's largest religious complex. Cambodia is the only country having a building on its flag, thanks to this iconic structure.

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.

USA's present 50-star flag was created by 17-year-old Robert Heff as part of a high school project. It was 1958, and there were only 48 states at the moment, but Heft had a feeling Hawaii and Alaska would get statehood shortly. His teacher gave him a B- but later raised the mark to an A after Heft submitted his design to the White House, resulting in a call from President Eisenhower announcing that it had been chosen as the official U.S. flag.

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.
