Rowland Hill, a schoolteacher from Birmingham, devised the postage stamp in 1839. He went on to construct Britain's first modern postal system.

Around the 15th century, the first toothbrush with bristles arrived on the scene in China. Bamboo sticks were outfitted with pig/boar hair, which had a scouring effect and quickly became more popular than ordinary chew sticks. Boar bristle toothbrushes were brought to Europe during the 17th century. Finding the boar bristles too abrasive, the Europeans began using horsehair instead, and some of the more affluent folks had special badger hair toothbrushes created for them. Bristled toothbrushes, on the other hand, were here to stay. Later types of bristles brushes would be constructed of bone, ivory, or other woods.

Halibut is, indeed, a flat fish. Flatfish can be mottled brown, black, and beige in colour, like the black sea turbot, or spotted, like the blue-and-yellow peacock flounder. The majority of species dwell in the various tropical and subtropical waters.

According to North Carolina State University researchers, the venom of the Brazilian scorpion Tityus serrulatus can cause pancreatitis. One specific venom enzyme targets specific proteins in the gland, impairing their functionality and causing inflammation in the pancreatic cells. Researchers discovered that although acute pancreatitis caused by scorpions is typically temporary and self-limited, it may develop into hemorrhagic pancreatitis and result in death in a separate study of a related species (T. stigmurus).

It is one of the oldest shops in the city and serves the most authentic samosas in the city. Also, heavenly gulab jamun is another specialty of the city.

Despite their small size, they work extremely hard and it shows. If given the chance, their voracious appetites can obliterate entire homes and businesses! Termites damage property every year to the tune of billions of dollars, as was previously stated. Termites alone damage structural property in the US to the tune of $5 billion. Don't ignore the issue and incur unanticipated costs. You must have an inspection performed as soon as you suspect termites or another pest. Wood emits vibroacoustic signals that help pests decide which food source to infest next.

Few visitors to Budapest are aware of the little church on the rock beneath Gellert Hill in Budapest Old Town. Despite being surrounded by so many grandiose churches, Sziklatemplom ('Rock Church') is relatively unknown. If you happen to be near the Liberty Bridge (the green metal one), you can visit this strange chapel founded in 1926 by a group of Pauline monks. The Cave Church (which is still in use) is not spectacular, but it is charming in its own right. Off the beaten path, but worth a 30-minute detour.

Jules' wallet in Pulp Fiction that reads "Bad #&$&*@$" actually belonged to the director—who picked it up because of its reference to the 1971 film Shaft. As it happened, Samuel L. Jackson would go on to play the character that inspired the wallet in the 2000 remake of Shaft.

Unfortunately, this is not good news for men. Depending on the species, the female spider may consume the male spider before, during, or after copulation! Did you know that this sexual cannibalism behaviour inspired the names of widow spiders like the black widow?

The Vent Haven Museum has a collection of vintage ventriloquist dummies.
Ventriloquist dolls can be quite creepy, and a museum containing hundreds of ventriloquist dolls is almost certainly a horror movie destination for many. The Vent Haven Museum in Fort Mitchell, Kentucky, houses over 900 ventriloquist dolls and other related items such as photographs and replicas.

Even more "folded" than the human brain, the dolphin brain existed millions of years before the emergence of humans. Scientists frequently gauge IQ by counting the "folds" in the brain.

The easternmost city in the United States is appropriately named "Eastport" in Maine, close the Canadian border. Every day, it is the first place in the country to see the sun. Eastport is also well-known for whale sightings since the surrounding water is ideal for feeding and rearing young whales.

The first tightrope walk occurred in 1859, when Charles Blondin wore pink tights and walked a one-inch-thick tightrope over a part of Niagara Falls. Blondin returned to Niagara Falls numerous times more, including one excursion while blindfolded. In 2012, Nik Wallenda became the first person to walk across the Niagara Falls on a tightrope. Wallenda walked in front of tens of thousands of people and had his journey broadcast live on television.

If you travel to other huge Asian cities, you'll frequently discover that if you know English, life may be rather simple. If you visit Singapore or Hong Kong, you will see that English is one of the official languages. In Singapore, more people speak English at home than any other language. Over half of the people in Hong Kong speak it. If you want to get by in Tokyo, you'll need to acquire a little Japanese; otherwise, even the most ordinary chores would be difficult.

It's true whether you believe it or not. Pineapple contains an enzyme called bromelain, which is a little-known fact. If you read other sources, you'll notice that they all say pretty much the same thing. This enzyme degrades proteins in your mouth, specifically your taste buds. This can ruin your palate for the rest of the day until your mouth heals. A fun fact that many people believe is that the enzyme bromelain is used in meat tenderizer. Pineapple is a fruit, so it's good for you. However, you should let a freshly sliced pineapple sit in the fridge for a few minutes before eating it so the enzymes can break down.

The US Geological Survey (USGS) studies the invaders using marine lampreys caught in traps. They separate the females and kill them to restrict their reproduction. Before being released back into the Lakes, the males are injected with a sterilant to prevent subsequent progeny. It's unknown why they don't kill the males as well, but it's possible that such attempts would be too swift and disrupt the ecosystem's equilibrium (even if it is currently weighted in favour of the destructive sea lampreys).

Bihar became the first state in India to replace Urdu with Hindi as its single official state language in 1881, becoming the first state to do so.

The fundamental technology behind windmills was undoubtedly derived from the wind sails that were used to steer ships. However, the first instance of wind energy being used to help automate routine manual tasks, such as pumping water or grinding grain, was most likely in Persia. Last but not least, the first vertical axis windmill design that has been historically recorded is the Persian panemone windmill, with records of the technology dating back as far as 1,500 years. The vertical sail on this particular specimen was made of bundles of reeds or wood, which were then fastened to the central vertical shaft with the aid of horizontal struts.

That equates to nearly 140 million individuals. Scotland has the largest percentage of genuine redheads, with 13% (40% may possess the gene), while Ireland is second, at 10%.

Hong Kong's skyline is always a sight to behold, with over 8,000 sparkling buildings. A skyscraper is defined as any structure with more than 14 stories, and Hong Kong has twice as many as New York City. With 118 stories, the International Commerce Centre (ICC) building is now Hong Kong's tallest skyscraper.

The most sacred symbol or syllable in Hinduism is OM or AUM. It is frequently chanted as a prefix to any mantra. It has also been suggested that when OM is chanted, its vibration is 432HZ, which is the vibrational frequency of everything in this universe.

The waters surrounding Malta and Gozo are a stunning combination of blue and green. The most popular site on the Maltese islands is the Blue Lagoon on Comino Island.

Melanism can be an advantageous evolutionary process. Panther facts reveal that darker members of a species are frequently more disguised and so more likely to survive and reproduce. This is especially true in some environmental environments, such as deep woodland areas with minimal light, where melanism is more widespread. Melanism is thus passed on by a dominant gene in Panthera onca, the kind of panther derived from the jaguar species. This implies that although black jaguars can have either black or spotted offspring, normal jaguars can only have spotted cubs.

Lyndon B. Johnson, ever the joker, would surprise guests at his Texas ranch by driving them down the hill in his Amphicar, pretending the brakes had failed. When it struck the lake, their fear would dissipate as they learned the automobile was built to work in water.
