Speaking of heavily inhabited places, Manhattan, the most densely populated of New York City's five boroughs, has over 200 zip codes. Some buildings are even large enough to have their own elevator. The Empire State, Chrysler, and MetLife buildings are just a few examples of structures that have exclusive rights to their own unique zip code.

On the tragic evening of April 14, 1865, Samuel J. Seymour was just five years old when he went to see a play at Ford's Theater. He was sitting directly across from the president in the balcony and claims to have heard the gunfire, seen Lincoln fallen over, and seen John Wilkes Booth climb onto the stage before leaving. Seymour related the incident on the CBS TV show I've Got a Secret on February 9, 1956, two months before his death. History is closer than you believe!

Chronic kidney disease affects over 31 million individuals in the United States and is the tenth largest cause of death, making kidney transplants quite frequent. But did you know that the surgeon doesn't always remove the damaged kidney? The old kidney is usually left in place, and the donor kidney is placed in the lower abdomen on the front side of the body.

There is evidence that pets, as well as insects, can suffer from insomnia. They gain more fat, learn more slowly, and lose their balance, all of which are symptoms of sleep deprivation in humans.

Do you believe that immortality is a pipe dream? It is, after all, for people. However, scientists have discovered that the Turritopsis dohrnii jellyfish may revert to its juvenile polyp stage after maturing, allowing it to continue in an unending cycle, making it the only officially immortal organism. Do you enjoy mind-blowing facts?

The collection of symptoms that strike women in the week or so before their menstrual cycle begins, has been the brunt of countless jokes and has even been suggested as a reason why a woman should not be elected president of the United States. Men, on the other hand, should stop giggling because medicine recognizes the male equivalent known as "irritable male syndrome," a behavioral state defined as "hypersensitivity, frustration, anxiety, and anger that occurs in males and is associated with biochemical changes, hormonal fluctuations, stress, and loss of male identity."

World War I was a disaster on scales that most of us alive now cannot understand. What about this as an example? The total number of fatalities. France lost about 1,360,000 men during World War I. In comparison, the United States has reported around 1,350,000 military casualties in total throughout all wars since 1775.

Do you believe The Walking Dead is a work of fiction? It is, but the government wants to be ready for a real-life version in any case. In 2011, the 31-page Counter-Zombie Dominance Plan, or CONPLAN 8888-11, was created. And, lest you think it's strange bureaucratic humour, the first sentence says, "This plan was not truly created as a joke."

In the 1940s, Anne Frank was an iconic emblem of Nazi cruelty, while Martin Luther King, Jr. was the face and voice of the civil rights movement in the 1960s. The two events appear to be so far apart in history, although both people were born in 1929—on January 15, 1929, for King, and on June 12, 1929, for Frank. That's a mind-boggling truth, isn't it?

Martin Lotze, a German researcher, studied the brains of both professional athletes and professional writers and discovered that their brain activity during athletic competition and the writing process was very similar. Lotze discovered an interesting difference between professional and amateur writers: professional writers used their speech-processing centres of the brain to develop their stories, whereas amateur writers relied on their vision centres to imagine the story first.

In the year 1897, machine-spin cotton candy was invented by the dentist William Morrison and a confectioner John C Wharton. These candies were first introduced to a wide audience in the year 1904 at 'Fairy Floss' and achieved great success.

We often get attracted towards the smell of the earth when it rains but have you have thought that rain too can have smell? But it does! Petrichor is the word that describes the scent of the rain. The reason behind it is that some plants secrete oild during dry periods & when it rains these oil get released into the air. And the aromatic compounds combine to create the pleasant scent of rain.

Raindrops appears to be very fascinating since childhood. But have you ever wondered about its shape? Raindrops are more like hamburger buns. As the raindrops fall they become more flattened at the bottom resembling hamburger buns. Isn't this interesting?

The English language evolves at a breakneck pace. A new word is added to the dictionary every two hours, according to one estimate. At regular intervals, the conventions for how to use words change as well. Some of the most popular style guides, such as Chicago, APA, MLA, and AP, for example, change their rules for how to use punctuation, pronouns, and specific words and phrases on a regular basis. To ensure that their writing is up to standard, writers must keep up with the latest style changes.

Many of us prefer to eat ice cream in dishes and many of us want to eat with a crunch of a cone. But the invention of the cone was actually an accident. It was in the year 1904 World's Fair, an ice cream maker was struggling to keep up the demands and eventually ran out of the bowls to serve ice cream. And luckily his stall was just beside the waffle maker and seeing his condition the waffle maker jumped in to help him out and he began to roll his waffles into the shape of horns to serve the ice cream and this is how we got cones.

Sounds little shocking but the word 'candy' has been originated from the Sanskrit word 'Khanda' which means, a piece of sugar. Then years later, the Arabic word 'qandi' stepped one step closer. And hence, candies began to call so in the 13th century.

This is referred to as the Triple Boil, and at that temperature, water exists as a gas, a liquid, and a solid all at the same time. It need highly precise circumstances, so don’t even think of doing it at home. Have you had your fill of amusing scientific facts?

When you burp on Earth, gravity keeps the solids and liquids from the food you just ate at bay, allowing only the gas to leave your mouth. Because the gas cannot separate from the liquids and particles in the absence of gravity, burping effectively becomes vomit.

This is paradoxical, yet it is known as the Mpemba effect, named after a Tanzanian student named Erasto Mpemba, who told his instructor that a hot combination of ice cream froze faster than a cold one. Scientists currently think this is because the velocities of water particles have a particular disposition while heated, allowing them to freeze more easily. If confirmed true, this discovery might have ramifications in everyday life, such as cooling down electrical equipment.

Bananas contain potassium, which decays and makes them mildly radioactive, making them one of our weirdest scientific facts. But this is one of those amusing science facts about which you need not be concerned. According to Forbes, you’d have to consume 10,000,000 bananas all at once to die of radiation exposure.

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.

Yes, indeed. When directing a laser beam through a container of water, a cool effect known as total internal reflection is used. Light is slowed by heavier particles in water as it passes through it, as detailed here. As a result, the laser beam is essentially “stuck” in the water.

Don’t worry if you accidentally swallow a razor blade. The human body is far more competent than you may believe. Acids are graded on a range of 0 to 14; the lower the pH, the stronger the acid. The pH of human stomach acid is 1.0 to 2.0, showing that it is powerful. Scientists discovered that the “thickened back of a single-edged blade” disintegrated after two hours of immersion in stomach acid in research.

According to scientists, all of the pyramids were erected between the 26th and 23rd centuries BC. Mammoths first arose approximately 1.6 million years ago and were extinct in the 10th century BC. This indicates that when Cheops was ecstatic about a new pyramid named after him, enormous beasts were terrorizing our forefather's thousands of kilometers distant.

According to research, many people who are not predisposed to becoming overweight perform “additional” motions over the course of their everyday lives, such as tapping their fingers, pacing in circles while chatting, and so on. Even this seemingly insignificant physical exercise aids the body in burning up to 350 additional calories each day. This implies that simply tapping your fingers can help you lose up to 30 pounds every year.
