One quiet little secret exists in Grand Central. The whispering gallery, also known as the whispering wall, is a modest secret that stands apart from the surrounding turmoil of city life. It is located on the less frenetic lower level and has no great fanfare to indicate its presence. Four arched entryways make a square shape in the whispering gallery. And if you whisper something into the arch and someone else stands 30 feet away with their ear to the arch diagonal from yours, they'll be able to clearly hear what you said — despite the distance and the acoustic deafening noise that is typical of Grand Central.

The age of language is still a point of contention. Nonetheless, most linguists agree that it started around the time modern humans (homo sapiens) evolved in Africa with modern skull shapes and vocal cords. Language evolved with the right tools in place — a large enough skull, a brain, and a voice box. Some anthropologists speculate that language may have evolved prior to the physiological development of modern brains and larynxes, but 100,000 BC is a good starting point

Though it would quickly cruise its way into film history, the script for Taxi Driver came together in just a few days. As screenwriter Paul Schrader told The Hollywood Reporter, "I crashed at an ex-girlfriend's place, and I just wrote continuously.

Chinese porcelain was first exported during the Han Dynasty (206 BC – 220 AD). Chinese porcelain was quickly introduced to Western countries as a result of the large-scale trade developed along the Silk Road routes.

It's strange to think of the founder of modern science dabbling in astrology. But two things should be kept in mind: First, historians warn us that judging historical events by today's standards is tricky. We all know that astrology is nonsense, yet astrology was only just beginning to separate from astronomy at the time of Galileo. Besides, Galileo was not wealthy: A professor who can teach astrological methods will be more in demand than one who cannot.

Robin Dunbar, a British anthropologist, developed Dunbar's number in the 1990s after discovering a relationship between the average size of a social group and the brain size of primates. The suggested cognitive limit for the number of people with whom someone can maintain a stable social relationship is 150. Exceeding this number is extremely rare, because becoming close to new people causes the quality of some older relationships to deteriorate over time

The Royal Spanish Football Federation grew preoccupied with inviting Lionel Messi to join the Spanish Football Team a few years after he arrived in Barcelona.

Pigeons were traditionally released from sinking ships to signal for aid. Pigeons have also been trained to assist in the rescue of persons who have become stranded at sea. They find the stranded individuals and tell rescuers of their position. They are ideal for this position because, in addition to possessing excellent vision, they can sense the UV radiation that surrounds the humans in the water.

Another interesting fact about Egypt is that Cleopatra, one of the most famous figures from ancient Egypt, is actually Greek, not Egyptian. While she was born in Alexandria she had no Egyptian blood and was instead a descendant of the Ptolemaic Dynasty which were a line of Greek Macedonians. The Ptolemaic Dynasty ruled ancient Egypt from 323 to 30 BC. The name Cleopatra is actually Greek for “Famous in Her Father” or “Her Father’s Fame”

There was Jesus Christ in Christianity. There is no prophet or founder in Shintoism. Instead, beginning with the Nara era, Shintoism was recreated with Buddhism as a single religion. This scenario altered during the Meiji period when the emperor's devotion was combined with Shintoism. Kokka Shintoism is the name given to this Shintoism. Kokka Shintoism died out after World War II. Nowadays, we have Jinja Shintoism, which is Shintoism that takes place in shrines.

A procedure to remove a cataract was first successfully carried out in 1747 by French ophthalmologist Jacques Daviel. The treatment was only carried out in the most extreme circumstances because the entire lens was removed. Unfortunately, other fields of medicine had not evolved as much.

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.
