We still only know about a small percentage of the marine species that live in our oceans. According to the World Register of Marine Species, there are now 240,470 accepted species, but this is thought to be only a small proportion of the species that exist, as new marine life is discovered on a daily basis.

If you ate a Macintosh apple and planted the seed, the tree that grew would produce apples that didn't look or taste like Macintoshes. Instead of planting seeds, growers graft a cutting from a genetically desirable tree onto an existing branch or sapling (called the "rootstock"), resulting in apples that are genetically identical to those on the tree from which it was cut. If you look closely at the tree in the photo, you can see that there are several different types of apples on the various branches, all of which are grafted onto the same rootstock tree.

The most common mode of transportation for citizens in Paris is the city's subterranean rail system, which is used by over 5 million people every day. It is Europe's busiest subterranean network after Moscow. Count your stations when using the subway - you never know where you'll wind up if you don't, as the Paris Metro system, unlike other big cities, does not announce its stops.

The Stonewall Inn in New York's Greenwich Village was raided by the police in 1969. It was a safe haven for the LGBT community, and rather than submitting, they fought back. Riots erupted as a result of the event, which sparked a global movement that has helped New York remain one of the most welcoming cities for gay people to this day. Indeed, more people identify as LGBTQ+ in New York than in any other American city (yes, we're giving you more NYC facts for free!).

However, Moldova's second language, Gagauz, is on the verge of extinction. The Turkic language, which is spoken in the Autonomous Region of Gagauz, is classified as severely endangered by Unesco.

Apple's initial iPod included a small Easter egg. This game could only be accessible if you knew the correct sequence of buttons to press. "Go to the 'Around' menu and hold down the center button for about three seconds to play a Breakout (Pong) game while you listen." Breakout, the hidden game, is significant in Apple's history since it was a product on which both Steve Jobs and Steve Wozniak collaborated at Atari.

Pilots are paid hundreds of dollars per day to stand by during the summer in case it rains and trees require emergency blow-drying. It may appear absurd, but it is worthwhile for farmers who grow the delicate, expensive fruit. The work is hazardous; pilots are frequently injured in orchard crashes.

The renowned "Bloody Mary" drink was conceived at the Ritz Hotel in Paris. According to legend, this renowned drink was created for the famed author Ernest Hemingway! Hemingway asked for a drink that didn't smell like alcohol, so he had vodka blended with tomato juice.

Have you ever considered where oxygen originates from? Your initial idea would be a rainforest, yet sea organisms are drawn in. Over half of the world’s oxygen is produced by plankton, seaweed, and other photosynthesizes.

According to new research based on minutes of conversations between Japanese government officials in the run-up to capitulation, the Soviet Union's surprise entry into the conflict with Japan had a more crucial impact.

It's an earthquake hazard area. Although several earthquakes have been reported in and around the Black Sea, the greatest recorded magnitude was 7.2 in the 1901 Black Sea earthquake (also known as the Balchik earthquake in Bulgaria). The mainshock triggered a 1-16 foot tsunami, wreaking havoc on the Romanian and Bulgarian shores. The aftershocks continued four years longer.

Kraft Foods once polled hundreds of Oreo eaters (see out these cookie butter Oreos!). They discovered that biters are more laid-back and self-assured, whereas dunkers are more active and daring. Twisters, on the other hand, are delicate and fashionable.

There are several theories as to how the phrase "it's raining cats and dogs" came to be. One example is that when houses had thatched roofs, pets and other small animals (squirrels, groundhogs, and so on) would nestle into the straw for warmth. When it rained, however, the straw became slick and the animals slid out, giving the impression that it was literally raining cats and dogs.

Even after being harvested, most fruits can still respond to their surroundings. Take, for example, the banana: A quick Google search will yield numerous methods for hastening the ripening of green bananas, as well as tips for preventing them from ripening too quickly. Avocados ripen or'soften' after being harvested as well!

The United Arab Emirates is a presidentially elected federated monarchy. It is a federation of the seven Emirates' absolute monarchy. The president of the United Arab Emirates is the emir of Abu Dhabi. The president is also the UAE Armed Forces' Supreme Commander in Chief and Chairman of the Supreme Petroleum Council. The Emir of Dubai, on the other hand, is the Prime Minister. These titles are passed down through the generations.

During International War I, Europe was at war, and world powers like Britain were organizing their armies. By 1917, one renowned British admiral of the Royal Navy had retired and wrote to Winston Churchill to express his thoughts on the day's headlines, some of which were so thrilling that he wrote, "O.M.G. (Oh! My! God!)." How could he have realized that the acronym he created would go on to become one of the world's most-used phrases?

Have you ever visited a salt mine? When you travel to Poland with Trafalgar, we will take you to the 800-year-old Wieliczka Salt Mine, one of the world's oldest. It's known as the Underneath Salt Cathedral of Poland, and when you go 135 metres (440 feet) underground with your guide, you'll witness chambers, sculptures, salt chandeliers, and an entire church sculpted from rock salt. The UNESCO World Heritage Site has been producing salt continuously since the 13th century until 2007, and the history and unique carvings of this salt mine will leave you speechless.

Since you were a child, you've probably heard the phrase "candy will rot your teeth." However, there are many foods that are worse for your dental hygiene than candy, such as crackers. This is because acid, not sugar, is the leading cause of tooth decay.

Another shocking fact about Russia is that it has 12 active volcanoes! Because of its convenient position, Kamchatka is one of the most visited of these volcanoes. If you enjoy nature and stunning scenery, you should go to Kamchatka. This active volcano is home to approximately 1,000 plant species. Brown bears, lambs, and wolves also live there. You may explore Kamchatka on your own or as part of a guided excursion. If you are not fluent in Russian, an organised trip is the better alternative.

Paris is the fashion capital, and the majority of well-known fashion brands are French (Chanel, Louis Vuitton, Dior, Jacquemus, you name it). Of course, they were the ones who came up with the military uniforms as well. The French were the first to deploy camouflage clothes in the military; the name "camouflage" loosely translates to "make up for the stage."

Not Andamanese or Nicobarese is the most widely spoken language on the islands. Bengali is the most widely spoken language on the islands, followed by Hindi, Tamil, Telugu, and Malayalam. Andaman Creole Hindi is also widely used as a commercial language in the Andaman Islands.

Being the first president of the United States apparently wasn't enough for George Washington throughout his lifetime. Following his presidency, Washington established a whiskey distillery. Washington's distillery was the largest in the country by 1799, producing 11,000 gallons of unaged whiskey. However, after the president's death, the company was no longer in operation.

Although the now-retro rainbow design is undoubtedly Apple's most well-known, the very first Apple logo depicted Sir Isaac Newton seated under a tree with an apple ready to fall on his head. The Newton logo was created by Apple's lesser-known creator Ronald Wayne and was only used briefly in 1976. Its high degree of detail didn't show up well when scaled down and put on a device.

Einstein was not a participant in the Manhattan Project, although he was essential in its inception. German scientists discovered nuclear fission of uranium in the late 1930s, which was a crucial step toward the construction of the atomic bomb. Much of the world's uranium was stored in the Congo, which was then a Belgian territory, so two Hungarian-American physicists called Leo Szilard and Eugene Wigner persuaded Einstein to send a letter to his friend, the Queen of Belgium. Instead, Einstein advised writing a letter to a Belgian minister, but a chance meeting with an economist who knew President Roosevelt resulted in a change of heart and a letter that pushed America to begin its own tests.
