The infamous Taj Mahal in Agra, built by Emperor Shah Jahan, is known to change colour every morning, noon, and midnight. Many people believe it is because of the white marble used in the construction, which is shiny and reflective. Others believe that the structure is infused with historical magic.

Japan paid a million yen to a team of scientists who claimed to develop a "death ray" that would use wave electric power to kill persons standing kilometres away, based on Nikola Tesla's ideas. The Japanese got as far as developing a prototype that could kill from half a mile away—but the victim had to stay motionless for 10 minutes for it to operate.

Under a microscope, dust mites appear somewhat menacing due to a pair of unsettling, pincer-like claws located close to their mouths. But do not worry; unlike lice and bed bugs, these tiny creatures are not parasites. They do not bite people and do not consume blood.

This species has a name that reflects its proportions, with wingspreads ranging from four to seven inches. If you've ever encountered one on a hike or in your yard, you may have been taken aback by its beauty. Because of the lengthy tails on this butterfly's hindwings, their swallowtail description is drawn from birds of the same name.

In ancient Greece, killing a dolphin was deemed sacrilegious and was a capital offence. They were known as "holy fish" or hieros ichthys by the Greeks.

The femur bone, found in the upper leg, is your body's longest bone. As a result, it can withstand hundreds of pounds of force and is extremely tough to break. Femurs have the ability to support 30 times your own weight! The majority of femur fractures are caused by severe vehicle accidents or falls from considerable heights, which can provide enough force to shatter the bone.

Uranus is a planet in the outer solar system, as many students are aware. Neptune is the next known planet beyond its reach, and another huge planet may exist much further away (nicknamed "Planet Nine" by the astronomers who proposed its existence). Surprisingly for planetary scientists, it turns out that Uranus is the coldest planet in our solar system, not Neptune. This is due to Uranus's lack of an internal heat source to augment the heat of the sun.

Kathryn Bigelow became the first woman to win the Oscar for Best Director in 2010 for her Iraq war thriller, 'The Hurt Locker in. Kathryn beat her ex-husband James Cameron who was up for the same award for his 3D epic 'Avatar'.

What happens after you save the world? Of course, you'll want to eat something. In The Avengers, our heroes go out for shawarma after winning the Battle of New York, but Steve Rogers, a.k.a. Captain America, doesn't appear to be partaking. This is due to the fact that Chris Evans had grown a beard for his next film, Snowpiercer, and was unable to shave it in time for the last-minute scene. The actor wore a prosthetic jaw to keep him looking like our fresh-faced Captain America (who wouldn't grow his own beard until Infinity War). He's not only not eating, but he's also covering half of his face with his hand.

The early toothbrushes were little more than "chew sticks," which were tiny frayed twigs used to scrape plaque and food residue off and between teeth. Twisting and rubbing these sticks against their teeth was a slight improvement over the traditional way of rubbing and cleaning the teeth with plants, feathers, or anything else. To refresh the breath, certain chew sticks were constructed from aromatic wood. Chew sticks have been found as far back as Babylon, Egypt, and China.

The colon is where the majority of probiotics are found, but there are billions more in our mouths, oral cavities, nasal cavities, oesophaguses, gums, and pockets of our pleural cavity (surrounding our lungs). They reside in our rectum, vagina, gastrointestinal tract, and stomach. inside of joints, armpits, toenails, between toes, urinary tract, inside our urinary tract, and several more locations!

Male fingernails grow more quickly than female ones. 3.5 millimeters are normally added to men's fingernails per month.

The pencil was a favourite of John Steinbeck and Ernest Hemingway. Hemingway wrote letters on a typewriter but did his serious work with a pencil.

The Pacific Ocean is wider than the moon at its widest point, which stretches from Indonesia to Colombia. This ocean stretches for 12,300 miles, or more than five times the diameter of the moon!

Lamellae, a hair-like structure that lines the beaks and tongues of flamingos, helps them sift dirt and silt from their prey.

If you think conspiracy theorists are a minority, you're mistaken—at least according to one study. Political scientists J. Eric Oliver and Thomas Wood reported in 2014 that almost half of the American public believes in at least one conspiracy theory. Their findings were based on countrywide surveys that were conducted over several years. "We conceive of conspiracy theories as simply another sort of magical thinking," Oliver added, rather than seeing them as paranoid loners. People who believe in conspiracies are more inclined to believe in other sorts of magical thinking, such as the paranormal or the supernatural, according to their research.

Ancient trumpets made of silver and bronze have been discovered in Egyptian graves, and similar instruments have also been discovered in Scandinavia, Asia, and South America. The earliest trumpets, however, were used for military and religious purposes rather than for musical performance, so this does not imply that King Tut was playing in a jazz band.

One of the sweetest facts about the Netherlands is that the Dutch adore licorice. They eat around two kilos per person per year. That’s around 32 million kilos of the sweet treat consumed each year! 

You’ll be spoilt for choice, with shops in the Netherlands selling over 80 different kinds of drop (the Dutch word for licorice).

Panthers are carnivores that usually hunt on small to medium-sized herbivores, however which species vary on the area. Antelope, deer, warthog, tapir, wild boar, rabbits, and birds are among the animals that can be eaten. There are several panther facts pertaining to this animal's strong hunting abilities. Panthers are distinguished from other large cats by their ability to remain hidden. Panthers hunt at night since they are nocturnal. Their black fur lets them to blend in with their environment, and their keen eyesight and sense of smell aid in the detection of prey.

Both the beet and its greens are exceptionally good sources of manganese, copper, potassium, and vitamins A, K, and folate.
The high fiber content of beets promotes regularity and satiety.

Females tend to live longer than males, and they also mature sexually more quickly. Within the first year of life, male and female round stingrays, a species known for their rapid growth, reach 58% and 70% of their entire size, respectively. Males only live five to seven years on average, while females live an average of 15 to 22 years.

In her teen years, Anne briefly moved away from home to attend a boarding school, and at the age of nineteen, she started working as a governess. She worked as a young governess for several years, and her first book, Agnes Grey, is based on her experiences in this field. The protagonist's tale emphasises the long hours, meagre pay, and cumulative humiliations that characterised one of the only professions available to women.

Even though the first cataract extraction operation was conducted in the 18th century, cataracts have really been treated for a much longer. In actuality, the earliest known cataract operation took place in the fifth century BC. As a result, it ranks among the earliest surgical techniques ever performed. The methods employed then were undoubtedly less advanced than those used now or even in the 18th century. When the lens was fully opaque and hard, a procedure called "couching" was applied. This involved poking the eye with a sharp item or striking it with a blunt one.
