The music of Wilhelmus, the Dutch national anthem, dates back to between 1569 and 1572. This makes it the oldest melody used in a country’s national anthem, although it did not become the official Dutch anthem until 1932.

Queen Victoria of the United Kingdom penned this in 1841, following the British takeover of Hong Kong. Possession Point, where the British first raised the Union Jack, was known as Tai Hang Hau, or 'great puddle.' It was accumulating water directly on the island's shoreline.

If you think your current steering wheel is complex, wait till you see what Formula One drivers have to deal with. Their steering wheels can have up to 25 buttons. Every button and switch controls every part of the vehicle, giving the driver complete control. It is even stated that pressing the wrong button might lose a race. To put that into context, some buttons alter the way the brakes operate, allowing the balance to be adjusted in split seconds. These modifications might cause the automobile to behave differently from corner to corner. Talk about power!

In 1920, German citizen Hans Riegel of Bonn founded his own confectionery business. He was tired of his unfulfilling job as a confectionery worker. He initially made hard, colourless sweets, and his wife delivered them for him. When his hard candies stopped selling at street fairs, he had the idea to make fruit snacks out of gelatin. The recipe wasn't entirely his own invention, but he did perfect it. They draw influence from Japanese rice candies and Turkish delight.

No, this alleged torture gadget did not exist. The widespread usage of the term "mediaeval" is a typical 18th-century fiction, fueled by conceptions of the Middle Ages as a generally uncivilised era of murder and mayhem. (They weren't awful, but they weren't great.)

If blessings are on one side of the coin, an evil eye is on the other. We can't refute it; all we can do is shield ourselves from it. Tiger Eye Gemstone has served as the wearer's protector. The stone keeps opponents' ill will and jealousy from close relatives at bay. If you know of someone in your family who is always sick or who becomes sick after a certain incident, purchasing a protection stone for them might be the first step in establishing a protection wall around them.

Stephen Strange has always been more about intelligence than brute strength. Strange wins by out-thinking his opponents rather than out-zapping them, which is part of what made the Lee/Ditko run remarkable. He can pack a punch when necessary, both physically and magically. Mordo creates a whole cult to seek down his archfoe in Strange Tales #130 and 131. They get a nasty surprise when they approach him from behind before he can cast a spell: Stephen's magical training includes martial arts. They are really potent. Defenders #9 demonstrated that Strange is more than just skilled. He can compete with Mantis, who is among the finest Marvel martial artists.

I thought it was only available in South Africa. Think again. Particularly Namibia has a sizable population of Afrikaans speakers, which is a neighbour of South Africa. Argentina, more specifically Patagonia, where a tiny community of Afrikaans-speaking farmers live, is unquestionably the most intriguing region. They are descended from an Afrikaner migration to South America that took place between 1903 and 1909, following the Anglo-Boer War, and involved roughly 800 people. Amazingly, the language has persisted among a select few of them up until this point.

The Maratha Empire's Peshwas shifted their base from Saswad to Pune after assuming power, making Pune their main administrative centre. Pune has ties to numerous important political and historical events.

D.W. Griffith's "The Birth of a Nation," the first film to be screened at the White House, was shown in the main building. President Franklin D. Roosevelt converted the East Terrace cloakroom into a movie theatre in 1942, when the East Wing of the White House was built. The First Family and their guests will be seated in 42 seats in the theatre.

Most Star Wars fans are already aware that Yoda's full name, at least in the original draught, was "Minch Yoda," before being condensed to something simpler to say. But here's an interesting statistic that may surprise you: Yoda's original name was—wait for it—Buffy in the very early phases of The Empire Strikes Back. Yes, Buffy, the name we associate with great young vampire slayers. If Yoda had been given this extremely un-Yoda-like name, the world would have been a very different place.

When the cashew apples mature, they are taken from the tree limb with the seeds still attached. Then the one-of-a-kind harvesting procedure begins. The seed is manually twisted and picked out while still in its shell, then dried and steamed. It must be frozen and cooked after drying before it can be extracted from its shell. Cashews are dried and roasted after harvesting in a long process that removes harmful oils and makes the shell brittle and simple to remove.

Termites produce a lot of gas as they break down the wood and other materials they've eaten. Considering the size of a termite, this may not seem like much, but the gas accumulates. In fact, this amount is so large that termites are responsible for about 20 million tonnes of methane emissions annually on a global scale. That much gas is a lot!

The eye disorder known as heterochromia is characterized by the presence of two distinct hues, one in each eye. When the colors are quite distinct, like green and blue, it looks absolutely intriguing.
