History, at first glance, is a simple enough concept — a series of events that happen in chronological order and that eventually add up to the overarching story of humanity. However, sometimes it doesn’t take much to throw off our sense of that timeline. Historical outliers, anachronisms, and different types of development made by disparate cultures can intersect in ways that make you question your hold on temporal reality. These six facts will challenge your perception of time, and prove that history isn’t always as simple as it may seem.

George Washington Didn’t Know Dinosaurs Existed

The birth of the United States dates back little more than 245 years, but a lot has happened since then. One of the big paleontological updates, for example, is the discovery of dinosaurs. The first dino fossil ever discovered was in 1677, when English naturalist Robert Plot found the femur of what we’d now call a megalosaurus. However, Plot believed that this bone belonged to some ancient race of giant humans — not the animals we know today as dinosaurs. It wasn’t until the 1820s, when geologists in England uncovered more megalosaurus fossils, as well as bones belonging to the iguanodon, that they correctly identified the remains as belonging to some sort of giant extinct reptile. Even then, it’d take nearly two decades before the word “dinosaur,” meaning terrible lizard, was officially coined by Richard Owen. That means George Washington, and most of the founding generation of the United States, didn’t know anything about dinosaurs, and may have even believed an ancient race of human giants once roamed the Earth.

Woolly Mammoths Were Alive After Egyptians Built the Pyramids

Woolly mammoths were once hunted in Europe by Neanderthals, so it seems weird that they overlap with the recorded history of Homo sapiens. Yet the gargantuan beasts still roamed the Earth when the Egyptians toiled away on the Great Pyramid of Giza. Though “roam” may be a bit of an exaggeration: By the end of their natural time on Earth, woolly mammoths were completely confined to Wrangel Island off the coast of northeastern Russia.

This small island, roughly the size of Crete, saw the last gasps of this species, as the ice age that sustained the creatures’ survival completely receded. Sadly, the few mammoths on the island suffered what scientists call a “genomic meltdown,” as inbreeding affected the species’ ability to mark territory and mate. It’s estimated that the last woolly mammoth died around 1700 BCE, about 800 years after the completion of the Great Pyramid. However, new advancements in genetics could see the return of these woolly beasts to the planet.

The First Computer Was Invented Before the Roman Empire

A computer found in an ancient shipwreck among the islands of Greece sounds like a sci-fi story with a dash of time travel — but in this case, reality is stranger than fiction. Now regarded as one of the most astounding archaeological finds in history, the Antikythera Mechanism, named after the nearby island where the shipwreck was discovered, is an ancient analog computer built around the second century BCE. The machine was used to calculate eclipses, moon phases, and the movements of the five planets known to antiquity: Mercury, Venus, Mars, Jupiter, and Saturn. This means humanity’s conception of a computer predates the rise of the ancient Roman Empire, which began with the reign of Emperor Augustus in 27 BCE.

When the mechanism was discovered in 1900, no one knew how these strange, greenish pieces of bronze fit together, and the mystery wasn’t solved until historian Derek J. de Solla Price figured it out in the 1950s. Yet to this day, experts aren’t sure who originally created the Antikythera Mechanism; the famous mathematicians Hipparchus and Archimedes are good guesses. The next analog computer to rival the complexity of the Antikythera Mechanism didn’t arrive until the astronomical clocks of the Renaissance, more than 1,500 years later.

The Fax Machine Was Invented the Same Year the First Large-Scale Wagon Train Traveled the Oregon Trail

Although we often associate it with the late 20th century, the fax machine is surprisingly old, and it arrived little more than a decade after the invention of the telegraph. In 1843, Scottish mechanic and inventor Alexander Bain received a patent for a device now regarded as the first fax machine. This machine worked differently than today’s digital machines, however; Bain leveraged his experience as an amateur clockmaker to synchronize pendulums with a clock. One pendulum scanned an image, while another created a copy of the image.

That same year, on May 22, 1843, a wagon train left Missouri on its way west toward Oregon. The nearly 1,000 settlers were part of the first large-scale expedition to travel along what became known as the Oregon Trail, a route that wound through Wyoming’s South Pass and circumvented the Rocky Mountains. (While migrants had been using the Oregon Trail since the 1830s, numbers increased significantly with this Great Emigration of 1843.) Meanwhile, in England, Bain’s machine — and subsequent machines like it — were labeled “copying telegraphs,” though they became obsolete by the early 1860s, after Italian inventor Giovanni Caselli invented the telefax machine, known at the time as the pantelegraph.

The First University in Europe Was Founded 7 Years Before the Crusades

Universities, which served as centers of learning for the intellectual revolutions of the Renaissance and Enlightenment, seem like institutions founded after the unenlightened barbarism of the Crusades. However, the University of Bologna predates Pope Urban II’s call to retake the Holy Land by about seven years. The university formed as an affiliation of guilds mostly studying civil and canon (aka religious) law. By the 12th and 13th centuries, the University of Bologna attracted students from all over the world, and subsequently became a model for other Italian universities and centers of learning further abroad. The only university older than Bologna is the University of al-Qarawiyyin in Fes, Morocco, which was originally founded in 859 CE.

Nintendo Existed Before the Death of Civil War General William T. Sherman

On September 23, 1889, Fusajiro Yamauchi founded Nintendo Karuta in Shimogyō-ku, Kyoto, Japan. Many decades removed from the creation of the first video game, Nintendo’s early years focused on producing hanafuda, or Japanese playing cards. Two years later and half a world away, one of the most influential generals in the U.S. Civil War — William Tecumseh Sherman — died at the age of 71. Nintendo remained relatively unknown in the U.S. until the mid-20th century, when the company began exploring ways to expand, and even struck a deal with Disney to create hanafuda with its characters on them. But it wasn’t until the 1970s, when Nintendo became the Japanese distributor of the Magnavox Odyssey, the world’s first home video game console, that the company took a hard right turn into the new entertainment industry.

“Pharaoh.” The word conjures up images of ancient wealth, divine power, and Yul Brynner in The Ten Commandments. The royal title was applied to Egyptian kings beginning with the New Kingdom (circa 1539 to 1070 BCE), a period of revitalization following the expulsion of rulers who had come from modern-day Syria and Israel. The New Kingdom saw an explosion of Egyptian culture, wealth, and influence, as pharaohs including Thutmose III, Hatshepsut, Akhenaten, Tutankhamun, and Ramses II expanded the kingdom’s borders and built monumental temples and tombs. Read on for more insight into the pharaohs’ place in history.

Pharaohs Were the Political and Spiritual Leaders of Egypt

The most important duty of pharaohs was preserving the cosmic order, called maat, which they did by enacting laws, defending the kingdom against its enemies, managing all the land (which belonged to the pharaoh), and even collecting taxes. Both pharaohs and ordinary Egyptians were expected to live according to the moral principles of maat, but the pharaoh was additionally tasked with maintaining peace between the gods and the people and keeping chaos at bay. As the intermediaries between the gods and humans, pharaohs led religious festivals, built temples honoring deities, and carried out divine imperatives.

Pharaohs Identified With the Gods Horus and Osiris

The story of Osiris, the Egyptian god of the underworld, fertility, and rebirth, forms the foundation of ancient Egyptian kingship. In the myth, Osiris was the first king of Egypt and ruled with Isis, his queen. Benevolent Osiris taught the people to prosper, but he had an evil brother, Seth — embodying the opposite of maat — who killed and dismembered Osiris so he could take the throne. Isis was able to put his parts mostly back together, and Osiris became the god of the underworld, while his son Horus got revenge on Seth and became pharaoh. (According to one story, Horus killed Seth with a spear after the latter had transformed himself into a hippo.)

The legend served as a model for the actual pharaohs, who were identified with Horus during their lifetime and then with Osiris after death, and whose rule was characterized as a continuation of the existential battles between Horus and Seth.

Pharaohs Were Believed to Control the Nile

The Nile was central to ancient Egypt. It provided food and water, fertile lands for agriculture, and a blue highway for travel and shipping — and without the river, it’s unlikely that the desert dynasties would have existed. Its annual flooding, which replenished the lands for crops and livestock, was personified in a god named Hapi who had green or blue skin (representing water) and a pot belly (signifying fertility and abundance). As the religious leaders of the Egyptian people, pharaohs conversed with Hapi to ensure the flooding occurred on time. But if the floods were too strong or destroyed homes and farms, the pharaohs were blamed for not keeping the cosmic order up to snuff, which led to political instability.

Women Were Influential Pharaohs

Generally, pharaohs were men whose power passed to their sons, but some female pharaohs ruled Egypt in their own right. Hatshepsut, the queen of Pharaoh Thutmose II, rose to power after his death and reigned as pharaoh from 1472 to 1458 BCE. She led military campaigns and built massive temples, and at the height of her influence was depicted in statuary as a muscular, bare-chested monarch wearing a false beard like male pharaohs sported.

Scholars debate whether Nefertiti ruled explicitly as pharaoh in the 1330s BCE, but it’s certain that she was the queen of Pharaoh Akhenaten and likely the stepmother of another pharaoh, Tutankhamun. She is shown in artifacts in ways normally reserved for pharaohs — and then there’s that undeniably regal bust of Nefertiti, unearthed in 1912, which fueled speculation about her true role. She may have assumed power after Akhenaten’s death while Tut was still young, but the debate continues.

Cleopatra VII, who reigned from 51 to 30 BCE, is probably the most famous female pharaoh of all, thanks to the 1963 Hollywood epic starring Elizabeth Taylor. Though that movie focuses on her love affairs, Cleopatra was much more than a seductress; she was a popular ruler who made reforms of the monetary system, helped increase Egypt’s wealth through trade with Eastern nations, and allied with Roman factions in an attempt to keep Egypt independent.

Pharaohs Were Buried in Extravagant Tombs

Pharaohs were laid to rest in huge, richly ornamented tombs to ease their transition to the realm of Osiris. In the Fourth Dynasty (2575 to 2465 BCE) of the Old Kingdom, the three Pyramids of Giza were commissioned for the pharaohs Khufu, Khafre, and Menkaure. Each pyramid there is essentially solid stone with a small burial chamber at ground level or underneath; unfortunately, thieves plundered the tombs centuries ago, and the items buried with the pharaohs to aid them in the afterlife are lost.

A thousand years later, in the New Kingdom, pharaohs were buried in smaller, multi-chambered tombs in the Valley of the Kings, about 330 miles south of Giza. About 64 tombs are scattered across the valley, including those of Thutmose I and his daughter Hatshepsut, Ramses II (aka the Great), and Tutankhamun. All but Tut’s were looted long ago, which is what made the 1922 discovery of his nearly intact tomb, with its hoard of gold objects and furniture, a world-shaking event.

Pharaohs Issued Curses — But Not the One You May Be Thinking Of

According to legend, King Tut supposedly cursed the British archaeologists who disturbed his eternal rest. Roughly nine people involved in the tomb’s excavation died within a few years of their discovery, which the media whipped into stories about a “curse of the pharaohs.” No actual curses were found inside Tut’s tomb, however, and the Egyptologist David P. Silverman argues that pharaohs rarely issued them, since they already enjoyed protections from the gods. The few known royal curses serve as warnings against enemies of Egypt or members of court, and they could be pretty graphic.

“As for [anyone] who will come after me and who will find the foundation of the funerary tomb in destruction,” a curse in a temple devoted to Pharaoh Amenhotep warns, “His uraeus [a serpent-shaped headdress ornament] will vomit flame upon the top of their heads, demolishing their flesh and devouring their bones.”

How well do you know France? This perennially popular country is the most-visited nation in the world, with 212 million people arriving in 2018 (the most recent year data is available). Here are a few things you might not know about the land of baguettes, crepes, and the Eiffel Tower.

It’s Home to One of the Oldest Department Stores in the World

The first department store to open in Paris was Le Bon Marché, which Aristide Boucicaut founded in 1838. Some say it was the first store of its kind in the world, although there had been a small department store in London called Harding, Howell & Co. that operated in the same way, but on a smaller scale, from 1796 to 1820. Boucicaut learned his trade from his father, who had a small shop selling accessories such as ribbons and buttons. At 18, Boucicaut peddled fabric on the streets before moving to Paris in the hope of making it big. He believed in the success of  bulk buying, which would allow customers to browse before purchasing, and insisted on fixed prices with seasonal sales. These ideas were revolutionary and eventually made him a fortune.

There Are a Lot of Weird Laws

France has some peculiar laws. In 1954, the mayor of the wine-growing town Châteauneuf-du-Pape issued a decree banning the “flying over, landing, or taking off of flying saucers.” No one since has thought to overturn it, let alone consider what they’d do if a flying saucer actually landed. Another famously odd law concerns transporting your pets by train. You need to purchase a ticket for your furry friend, and as long as your fellow passengers don’t object, you can board with your dog, cat, hamster, guinea pig, or even snail. It’s worth an appeal, however, if it’s the latter; in 2008, someone scored a refund after they were forced to buy a ticket for their snails.

The French Eat a Lot of Cheese — But Not the Most

Perhaps surprisingly, the people of France aren’t the top consumers of cheese, nor the biggest exporter. That said, the French do eat and sell a lot of the stuff. In 2018, France was the third-largest exporter of cheese after Germany and the Netherlands, sending approximately 689,000 tons abroad. According to the International Dairy Federation, the French ate roughly 57 pounds of cheese per capita in 2013 alone, though they have since slid down the rankings despite eating more and more of the stuff. The country that consumes the most cheese per capita? Denmark.

There’s a Competition Devoted to Black Pudding

Like many other countries, France has a love of black pudding, which is also known as blood sausage. There’s even a festival devoted to this love-it-or-hate-it culinary treat in the town of Mortagne au Perche in Normandy. The Boudin Noir festival in March features a competition to see who can eat the most, and it’s conducted under the watchful eye of the Confrérie des Chevaliers du Goûte-Boudin — which translates to the Fraternity of the Knights of the Blood-Sausage Tasters. It’s common for contestants to consume up to three miles of black pudding between them.

The International Distress Call Has French Origins

“Mayday” is the international distress call and it derives from the French phrase “M’aider,” which translates to “Help me.” Despite its French origins, it’s commonly agreed that the first person to introduce the term was not a Frenchman, but rather a Brit named Frederick Stanley Mockford. He worked at Croydon Airport near London as a senior radio officer. He coined the phrase in 1923 and chose French over English since a significant amount of air traffic at the time originated from the opposite side of the Channel. To this day, if an aircraft is in trouble, the word is repeated three times.

The Country of Pommes Frites Once Made Potatoes Illegal

The French government banned potatoes in 1748, believing that they caused leprosy. In those days, the now-popular tuber was deemed “hog feed” in France and considered unfit for human consumption. But thanks to the work of French pharmacist Antoine-Augustin Parmentier, who was fed a potato-heavy diet while a prisoner of war and went on to publish a prize-winning, potato-promoting essay called “Inquiry into Nourishing Vegetables That in Times of Necessity Could Substitute for Ordinary Food,” the potato eventually gained both scientific approval and public acceptance. Parmentier also held dinners featuring potatoes in a bevy of different dishes (Benjamin Franklin and Thomas Jefferson attended a few). In 1794, a woman named Madame Mérigot published the first potato cookbook, and the rest is history. Today, as an alternative to pommes frites, you can eat Parmentier potatoes — named after the man himself.

The 1940 animated film Pinocchio is a beloved classic, featuring lovable characters and technical achievements that have stood the test of time. Despite being just the second animated feature Disney ever produced, the movie is often considered a masterpiece, and one that helped solidify Walt Disney as a visionary. In celebration of the film’s timeless appeal, here are six facts about Pinocchio that we promise are no lie.

Jiminy Cricket Wasn’t Originally Meant To Be Narrator

It may be hard to imagine the story of Pinocchio without Jiminy Cricket, but in the original source material, the beloved talking insect had a significantly smaller role. In Carlo Collodi’s 1883 book Pinocchio, from which the movie was adapted, Jiminy was smashed to death early on by an angry Pinocchio, who himself was also a much different and more mischievous character.

Disney felt that Collodi’s original interpretation wasn’t suitable for the silver screen, and decided to reimagine Jiminy as the narrator and voice of Pinocchio’s conscience. Disney tasked animator Ward Kimball with conceiving of a new design for the creature, which ultimately featured a tiny top hat and cane, and actor Cliff Edwards was brought aboard to voice Jiminy. Edwards was known for his rendition of “Singin’ in the Rain,” and as Jiminy Cricket, he sang “When You Wish Upon a Star,” which earned the film an Oscar (more on that below). Jiminy Cricket, of course, was a hit and continued to play a valuable role in future Disney anthology series; he has even been referenced in modern Disney Pixar films, such as A Bug’s Life and Up.

Mel Blanc Voiced a Character Without Any Lines

You’ve probably heard the voice of Mel Blanc, the man behind beloved cartoon characters Bugs Bunny, Barney Rubble, and more. But toward the beginning of his career, Blanc was still trying to make a name for himself, and repeatedly pushed Disney for an audition. His efforts finally paid off when he was cast as Gideon the cat in Pinocchio. He was paid $50 per day for 16 days of recording, during which he was asked to record several takes of his “drunk” impression, which features multiple hiccups. Upon the film’s release, Blanc was dismayed to find that all of his dialogue had been cut — except for a single hiccup. While Blanc would go on to have a prolific voice acting career working for Warner Bros., Pinocchio would be the only Disney-produced film he lent his talents to.

Blanc wasn’t the only famous voice actor to appear as an animal in Pinocchio, however. Thurl Ravenscroft was the voice behind the villainous Monstro the whale — and would eventually go on to serve as the voice of the cereal mascot Tony the Tiger.

“Pinocchio” Was Initially a Box-Office Bust Because of World War II

Made with an estimated budget of $2.6 million, Pinocchio initially struggled to earn its money back upon its debut in February 1940. The ongoing global conflict of World War II prevented the film from being released in European and Asian markets, and the result was dismal box-office numbers that especially paled in comparison to the film’s predecessor, Snow White. Initially, the film only grossed around $1.4 million. Thankfully, things improved from there: Beginning with its first re-release in 1945, after the war ended, Pinocchio went on to net $164 million at the box office, making a large profit in the end.

Walt Disney’s Favorite Character was Figaro the Cat

Of the many cats that appeared in Pinocchio, one stood out above the rest as Walt Disney’s favorite character. That was the black-and-white kitten Figaro, who went on to star in several short films of his own, including 1943’s Figaro and Cleo (which also featured Cleo the goldfish from Pinocchio). Figaro even appeared alongside other major characters such as Pluto and Minnie Mouse in various Disney titles that were unrelated to the Pinocchio universe.

In fact, Disney decided to make Figaro Minnie Mouse’s official pet, first replacing Minnie’s dog Fifi in the 1944 cartoon First Aiders. All told, Figaro’s minor role in Pinocchio was the beginning of eight total appearances in the Disney universe.

“Pinocchio” Was the First Animated Feature to Win a Competitive Academy Award

Walt Disney took home his first set of Oscars in 1933, seven years before Pinocchio’s release. In that ceremony, his short cartoon called Flowers and Trees was awarded an Oscar in the Best Short Subject (Cartoons) category, and Disney himself received a special award for the creation of Mickey Mouse. Disney also earned a unique honor in 1939 for his work on Snow White and the Seven Dwarfs, for which he was awarded a custom Oscar statuette placed alongside seven miniature ones.

At the 1941 Oscar ceremony, the success of Pinocchio earned Disney yet more accolades — the film became the first animated feature to win an Academy Award. Two, actually: The movie won both Best Original Score and Best Original Song, the latter for “When You Wish Upon a Star.” It was a rare feat for many decades, as no other animated film took home a Best Original Song Oscar until 1989’s The Little Mermaid finally won for “Under the Sea.”

Multiple Songs Were Cut From the Film

Known for its award-winning music, the final release of Pinocchio also left several songs on the cutting-room floor. The two most complete were “Three Cheers for Anything” and “Straight Ahead.” The former was meant to be sung by the wayward boys on their journey to Pleasure Island, and described all the “rotten things they’re going to do, like swiping a pie or telling a lie.” It was cut for pacing, however, as the tune dragged on for too long.

Straight Ahead,” meanwhile, was sung by the Blue Fairy (the being who brings Pinocchio to life), and offered words of wisdom to Pinocchio. That song was cut as Jiminy Cricket’s role in the film grew, thus rendering its message less important. There are also several snippets initially meant for larger songs that are instead used for a handful of measures at various points throughout the soundtrack. And while some songs copyrighted by Disney in 1939 were left off the final release, one of those, “Figaro and Cleo,” was later performed in the 1943 cartoon of the same name.

Did you know there are at least eight countries around the world with an eagle as their national animal? There’s only one country, however, that honors the Dodo bird. From mythical creatures to religious representations, here are six countries where a strange or unusual beast is a national symbol.

Mauritius: Dodo Bird

Mauritius, a tiny island nation east of Madagascar, was once home to the famed dodo bird. First seen in the early 1500s by Portuguese sailors, the dodo likely died out by the end of the following century. While the large, flightless, and ever-so-strange bird has been extinct for many years, Mauritius still honors its memory. Images of the dodo are found throughout the country — on the coat of arms, in tourist shops, and on government stamps. There’s even a full skeleton of the creature at the Natural History Museum of Mauritius, one of just a few such skeletons in the world.

China: Red-Crowned Crane

China’s national bird, the red-crowned crane, also happens to be one of the rarest cranes in the world. Named for the patch of red skin at the very top of its head, the omnivorous bird feasts on grasses and plants in addition to fish, crustaceans, and amphibians. Unfortunately, the bird’s population has been threatened by habitat loss. But since the red-crowned crane is synonymous with good luck, loyalty, and longevity, it is fiercely loved and protected by the Chinese people, as well as international conservation groups.

Bhutan: Takin

Bhutan’s national animal, the takin, is sometimes called a goat antelope, although it has more in common with wild sheep. Their powerful bodies and nimble legs help the creatures traverse the mountainous country, which is located in the Himalayas. According to legend, the shaggy creature was created by a Tibetan saint named Lama Drukpa Kunley, who arrived in Bhutan around the 15th century. Asked to perform a miracle, he rearranged the bones from his lunch of cow and goat meat so that the goat’s head was atop the cow’s carcass. With a snap of his fingers, the strange animal came to life. Today, although its population is vulnerable, the takin can still be found grazing in higher elevations of the country’s northwest and far northeast.

Belize: Baird’s Tapir

Although it may look a little like an anteater, Baird’s tapir is more closely related to a rhinoceros. The largest land animal native to Central America is surprisingly agile, however. It can swim in rivers, climb up steep embankments, and walk for miles in search of food. As an herbivore, it dines on grasses, aquatic plants, leaves, and fruits native to Belize. Its long, flexible snout and flat teeth make it easy to forage for hard-packed snacks, like twigs and nuts. Although the nocturnal animal is partial to nighttime ranging, it can sometimes be spotted in natural forest preserves throughout Belize.

Papua New Guinea: Dugong

The dugong, the national animal of Papua New Guinea, is cousins with the freshwater manatee. Often called a “sea cow,” this large, gentle creature can be found grazing on seagrass in bays, mangroves, and reefs. Dugongs have long played an important role in the lives of native Papua New Guineans, as the marine animal has been hunted for its hide, meat, and oil for centuries. Today, dugongs are protected by the nation, with the exception of traditional hunting.

Pakistan: Markhor

The markhor is a large, wild goat that lives in the Himalayas of Pakistan, as well as the neighboring countries of India, Afghanistan, and Turkestan. As the national animal of Pakistan, markhors are recognized as a protective symbol of the nation. In fact, the word “markhor” means “snake-eater” in Persian, which may refer to the goat’s ability to crush snakes with its large hooves or the animal’s serpentine horns. Unfortunately, this species is critically endangered — they’re often poached for their beautiful horns, which are believed to have healing purposes in certain traditional medicines.

For centuries, people have looked to owls as symbols of wisdom, mythical guides and protectors, and sometimes even spooky harbingers of death. About 250 species of these captivating birds, with their penetrating stares and mysterious vibes, live on every continent except Antarctica. Here are a few fantastic facts about them, from their asymmetrical ears to their unexpected connection to a medieval poet.

Owls Can Turn Their Heads 270 Degrees

No, owls can’t turn their heads completely around (as a popular myth suggests), but they can swivel three-quarters of the way. They have a few anatomical adaptations that make it possible, such as extra neck vertebrae that allow their heads to turn and rotate at multiple angles. But until a few years ago, it wasn’t clear how owls could do these moves without also twisting their arteries and cutting off blood to their brains. In 2013, a team from Johns Hopkins University injected dye, representing blood flow, into several owls that had died of natural causes, and then manipulated the birds’ heads. The dye pooled into “reservoirs” under the animals’ jaws, which suggested that when owls pivot their heads, these reservoirs maintain a supply of blood for their brains.

Owls Can’t Move Their Eyes

An owl’s eyes are proportionally enormous, comprising up to 5% of the animal’s body weight (for comparison, human eyes make up about .0003% of our total weight). Their huge size — along with pupils that dilate extra widely and a reflective layer at the back of their eyes to utilize available light — are adaptations for zeroing in on the movements of tiny rodents and other prey at night. However, they can’t move their eyes much in their tubular sockets. Owls do, however, have binocular vision (the ability to merge information from two eyes into one image, like humans), which increases their depth perception and allows them to judge the distance to their prey accurately.

Lopsided Ears Give Owls Excellent Hearing

They’re usually not very noticeable, but owls do have ears, and they serve an important role in hunting. Their ears are often situated asymmetrically, with the right ear a little higher than the left in most species. Sounds made by their prey, like rodents scratching in leaf litter, will hit each ear at slightly different times, allowing the owl to triangulate the location of the sound. Most owls also have circular patterns of specialized feathers to channel sound into the ears.
These anatomical arrangements pay off: Experiments with barn owls have shown that their incredibly sensitive hearing helps them find prey in complete darkness; they will often hover over prey and listen to its movements before striking. Great gray owls have also been observed successfully striking prey hiding under a layer of snow.

Their Silent Flight Has Inspired Quieter Machines

Owls sport specialized feathers that muffle the sound of their wings flapping and let them sneak up on a meal. The feathers on the leading edges of their wings have comblike structures that dampen air turbulence and cut down on “whooshing” noise, while finer feathers on the top and trailing edges further break up the sound, resulting in a virtually silent flight. Engineers have tried to mimic this quality when designing quieter aircraft, wind turbines, drones, fan blades, and more.

Not All Owls Are Night Owls

Most of the world’s owl species are nocturnal — they’re more active at night, with physical adaptations for hunting by moonlight. In North America, these denizens of the dark include the adorable, football-shaped northern saw-whet owl and the diminutive eastern and western screech owls. Some species can be seen hunting at dawn or dusk as well as at night; barred owls, great horned owls, and long-eared owls are considered crepuscular (most active at twilight). Diurnal species are primarily active during the daytime: Short-eared owls and snowy owls can often be seen flying over grasslands in search of rodents, while northern pygmy owls and northern hawk owls live in forests and are seldom spotted.

A Group of Owls Is Called a “Parliament”

This collective noun has an unusual literary source. In The Silver Chair, one of the books in C.S. Lewis’ Chronicles of Narnia, a talking owl named Glimfeather calls for his fellow owls to form a parliament; the group of birds advises the novel’s two protagonists on their quest. Lewis was actually riffing on a literary antecedent, Geoffrey Chaucer’s 14th-century poem A Parliament of Fowls, in which the narrator dreams that Nature gathers birds together to choose their mates. Thanks to the worldwide popularity of Lewis’ Narnia books, people began using the word “parliament” to define a group of owls by 1968, according to the Oxford English Dictionary.

If you’ve ever immersed yourself in an entirely different world while reading a book, you’re not alone. Stories that take place in intriguing locations are often the ones readers enjoy the most — in such books, the setting becomes almost as important as the characters themselves. Writers often draw inspiration for these stories from their real-life surroundings. Here are six fascinating locations that inspired some of the world’s best-known novels.

Forest of Dean, Gloucestershire, England: “Harry Potter” and “The Lord of the Rings”

Two of the world’s most famous book series share a connection: England’s fantastical Forest of Dean. Here, you’ll encounter winding paths, deep green foliage, looming moss-covered branches, and an air of hidden secrets within the trees. J.K. Rowling (Harry Potter) grew up in Gloucestershire and spent time in the forest, which serves as the inspiration for the series’ Forbidden Forest. There are also traces of her childhood cottage home here (which the author secretly purchased in 2011), such as in the tiny closet under the stairs that served as Harry’s bedroom.

J.R.R. Tolkien (The Lord of the Rings and The Hobbit) also spent time in the Forest of Dean as a child. He was inspired by the forest’s labyrinth of caves and geological formations called scowles, created by erosion in the limestone soil under the woods. Middle Earth, the elaborate setting for his books, contains several mystical forests such as Mirkwood, Lothlórien, Fangorn, and the Old Forest — all influenced by the Forest of Dean’s unusual features.

A popular area of the forest to visit is Puzzlewood, where you’ll find mazes, a café, a playground, farm animals, picnic tables, and a gift shop. Puzzlewood’s other claim to fame is as a film set — Star Wars: The Force Awakens, The Secret Garden, Dr. Who, Merlin, and Jack the Giant Slayer are just a few of the television shows and movies that have been shot here.

The Stanley Hotel, Estes Park, Colorado: “The Shining”

If you’ve read Stephen King’s horror thriller (or seen the movie adaptation starring Jack Nicholson), you’ll undoubtedly remember the hotel where most of The Shining takes place. Its long spooky hallways, eerily empty bar, and isolated location set the scene for the chilling tale. Estes Park lies on the edge of Rocky Mountain National Park, and due to the snowy, mountainous location, much of the park and town shut down for the winter.

In 1974, King was living in nearby Boulder and working on a novel titled Darkshine, but reportedly wasn’t happy with its setting. For a change of scenery and inspiration, he and his wife headed to Estes Park and spent one night in the Stanley Hotel, a 142-room Colonial Revival-style resort built in 1909. No other guests were in the hotel because the hotel was closing for the winter the following day. The couple dined alone in the large dining room with chairs on all the other tables as pre-recorded orchestral music played in the background.

When his wife retired to Room 217, King wandered the empty corridors and visited the hotel bar, where the bartender served him drinks. King reported having a disturbing dream that night about a firehose chasing his terrified young son down the hotel corridors. The nightmare, combined with the hotel’s eerie desolation, was the inspiration King was looking for, and Darkshine became The Shining, which takes place at the fictitious Overlook Hotel.

The Stanley Hotel, which overlooks the majestic Rocky Mountains and Estes Lake, has since been restored to some of its former grandeur. Room 217 is the hotel’s most requested room, and the hotel added a hedge maze to mimic the one in the movie. The hotel has a reputation for being haunted, and its rumored paranormal activities are often featured on TV shows and online.

Ngong Hills, Kenya: “Out of Africa”

Danish author Karen Blixen wrote Out of Africa under the pseudonym Isak Dinesen, chronicling her time living on a coffee plantation from 1913 to 1931 at the base of Ngong Hills in Kenya (when it was known as British East Africa). Blixen arrived in Africa in 1913 to marry her second cousin, Swedish Baron Bror von Blixen-Finecke. But the marriage eventually fell apart, and Blixen, who had fallen in love with Africa and its people, took over his plantation.

During this time, an English big-game hunter named Denys Finch Hatton became Blixen’s long-term romantic companion. The plantation eventually failed due to falling coffee prices, droughts, and an unsuitable elevation, and Blixen was forced to sell the land and return to Europe. But she never stopped longing for Africa and wrote her memoir detailing the breathtaking wildlife and vast savannahs around Ngong Hills.

In 1985, Meryl Streep and Robert Redford starred in a film adaptation of Out of Africa, directed by Sydney Pollack. The film was nominated for 11 Oscars and won seven, including Best Picture, Best Director, and Best Cinematography. (Streep received a Best Actress nomination.) Several scenes featured Streep and Redford against the stunning backdrop of the Kenyan landscape. Blixen’s plantation home, near Nairobi, has been converted to the Karen Blixen Museum. The fertile green Ngong Hills that Blixen wrote so favorably about lie just a few miles northwest of the museum and are a popular hiking spot.

Great Neck, New York: “The Great Gatsby”

F. Scott Fitzgerald’s masterpiece, The Great Gatsby, primarily takes place during the Roaring Twenties in West Egg and East Egg, fictitious towns on Long Island’s north shore. Both communities housed wealthy families who lived in lavish mansions, but with one significant difference — “old money” families who had been wealthy for generations lived in East Egg. Across a small bay, West Egg’s inhabitants were considered “new money.” Jay Gatsby, the main character, lived in West Egg and often threw elaborate parties. He pined for his love Daisy, who lived across the bay and married another man.

The two communities are based on real-life Sands Point (East Egg) and Great Neck (West Egg), separated by tiny Manhasset Bay. Fitzgerald and his wife rented a home in Great Neck from 1922 to 1924. They befriended some of its newer inhabitants, who had recently earned their wealth as famous writers, actors, and comedians. At the time, “old money” families such as the Vanderbilts and the Guggenheims owned estates in Sands Point.

Fitzgerald hosted and attended parties in both communities and often sat on the porch drinking in the evenings and watching the happenings across the bay in Sands Point, according to Ruth Prigozy, executive director of the F. Scott Fitzgerald Society. He started working on The Great Gatsby while living in the shorefront home, which still stands in Great Neck. (It sold for about $3 million in 2016.) Two of the Guggenheim mansions, Falaise and Hempstead House, still stand in Sands Point and are part of the Sands Point Preserve Conservancy.

Hannibal, Missouri: “The Adventures of Tom Sawyer”

Who can forget the lively adventures of Tom Sawyer in Mark Twain’s famous novel? The book is set during the 1840s in the fictitious town of St. Petersburg, Missouri, along the mighty Mississippi River.

Twain, whose real name was Samuel Clemens, grew up in Hannibal, and St. Petersburg is based on his boyhood hometown. He worked as a riverboat pilot on the Mississippi (among other jobs) before becoming a writer. Many of his boyhood antics made it into the novels, and several of the characters are based on people Twain knew. In the book, Tom and his girlfriend Becky get lost inside a cave for several days, and later cave scenes involve villains and buried treasure.

The real-life town of Hannibal has created several tourist attractions in honor of its most famous former resident. You can tour caves in the Mark Twain Cave Complex, take a cruise on the Mark Twain Riverboat, and visit his childhood house, which has been restored and converted to the Mark Twain Boyhood Home & Museum. You can even “paint” a replica of the whitewashed fence from one of the book’s most famous scenes in one of the museum’s interactive exhibits.

Whitby, England: “Dracula”

Gothic horror’s most famous villain, Count Dracula, lived in Transylvania, part of modern-day Romania. However, Bram Stoker, the Irish author who created him, never set foot in Romania.

In the novel, Dracula traveled from spooky Transylvania to Whitby, England — a seaside Victorian-era vacation destination — aboard the Russian ship Demeter. By the time the ship arrived in Whitby during a turbulent storm, the entire crew was missing, and the corpse of the captain was lashed to the ship’s steering wheel. Observers noted a large, black dog-shaped animal leaping from the ship’s deck to shore and running up the 199 steps to the Whitby church — the shapeshifting Dracula had arrived in England.

Stoker’s inspiration for Dracula began in Whitby during a four-week summer vacation in 1890. Stoker had already been working on a gothic tale about a character named Count Wampyr, set in Styria, Austria, when he discovered a book in the Whitby public library that mentioned a sadistic 15th-century prince named Vlad Tepes, who served as the inspiration for the world’s best-known vampire.

Stoker found additional inspiration in his surroundings. Looming over the town are the ruins of Whitby Abbey, an imposing Gothic church dating back to the 13th century. Perched on a cliff below is St. Mary’s ancient parish church, which can be reached by a 199-step stone staircase. The church’s adjacent cemetery contains many crumbling tombstones. As Stoker walked the abbey, church grounds, and among the graves, he noted names and dates that later showed up in the novel. Stoker also would have likely learned about an 1885 shipwreck of the Russian vessel Dmitry that was carrying a cargo of silver sand to Whitby, inspiring Dracula’s journey in the novel.

Whitby is still a popular seaside tourist destination and has embraced its Dracula connection. You can tour the abbey ruins and participate in various activities and tours that follow the novel’s events.

Dolphins are some of the most beloved creatures on the planet. After all, what isn’t to like about these seafaring cetaceans? They’re highly intelligent. They make adorable noises. They’re friendly to humans. They even like to surf. But beyond these crowd-pleasing theatrics, dolphins also boast impressive physiological capabilities and exhibit an array of mind-boggling behaviors. Here are six fascinating facts you may not know about them.

Dolphins Call Each Other by Their Names

The meanings behind much of the dolphin repertoire of squeaks, grunts, and clicks remain a mystery to marine biologists, but they do know that certain sounds represent an identifying call. For example, the common bottlenose dolphin develops a unique melodic pattern of whistles that makes it recognizable to others within earshot, even when murky underwater conditions distort the voice of the sender. Furthermore, recent research has shown that dolphins “address” each other by imitating the whistles of close companions and family, suggesting a capability for sophisticated interaction rarely seen outside the human world.

Dolphins Turn Off Half Their Brains to Sleep

As oxygen-dependent mammals that reside in water and voluntarily control their breathing, dolphins simply cannot let themselves slip into a state of complete unconsciousness. As a result, they experience what’s known as unihemispheric slow-wave sleep, in which only half the brain sleeps at a time and the other remains awake at a low level of alertness. Dolphins typically float motionless or swim slowly near the water’s surface when in this state, with the eye opposite the resting side of the brain remaining closed. And while people and dolphins have very different slumbering habits, dolphins typically get about four hours of slow-wave sleep for each side of the brain in a 24-hour period, which matches up with the doctor-recommended eight hours of shut-eye per night for humans.

Dolphins Teach Each Other to Use Tools

To further prove just how intelligent these creatures are: Bottlenose dolphins in Shark Bay, Australia, have been observed using marine sponges to protect their snouts when rooting around the seafloor for small fish. Mothers pass on this nifty foraging method to their offspring, though females usually show far more interest in learning than males. Additionally, scientists have observed dolphins in this region engaging in peer-to-peer learning for another technique known as “shelling.” The dolphins chase fish into empty giant snail shells, push the shells to the surface, and then tip the waiting prey into their mouths.

Dolphins Have Three Stomachs

While dolphins are cunning hunters, they forgo any semblance of dining manners by wolfing down their food without chewing. Thankfully, they have a three-chambered stomach designed to handle the rapid intake. The easily stretchable forestomach is primarily used to store the food, the main stomach is where the majority of digestion takes place, and the pyloric chamber completes digestion and regulates passage into the small intestine. This streamlined process supports the bottlenose dolphin’s average daily intake of 25 to 50 pounds of fish, squid, and crustaceans.

Dolphins Have Remarkable Powers of Recuperation

Dolphins possess something of a superpower when it comes to recovering from major tissue injuries. Dr. Michael Zasloff shed light on this ability in a 2011 letter to the Journal of Investigative Dermatology, in which he described studies of dolphins that had withstood significant flesh loss from shark attacks. These animals not only stemmed the blood loss and sustained no infections on the open wounds, but they also regenerated the torn-out tissue to regain their full-body contour within approximately 30 days. The dolphins displayed no sign of distress throughout the process, suggesting that a naturally triggered form of pain relief accompanies their extraordinary healing capabilities.

The U.S. Military Uses Highly Trained Dolphins

Since 1959, these smart, adaptable deep divers have served Uncle Sam in the Navy’s Marine Mammal Program, alongside a cadre of equally patriotic sea lions. Dolphins are typically taught to handle two tasks: They use their inherent sonar capabilities to pinpoint and mark the location of underwater mines, and they help apprehend uninvited swimmers by tagging the trespassers with a buoy that drags them to the surface.

And these dolphins aren’t just used for training simulations: Dolphins were deployed in the Vietnam and Iraq wars, and they currently help protect America’s large nuclear stockpile at Naval Base Kitsap outside Seattle, Washington.

In a metropolis filled with architectural marvels both new and old, the Empire State Building still carries major clout as a defining landmark of New York City. Whether it’s because of the classy art deco design, the attention-grabbing light displays, or the far-reaching views offered from its observation decks, the Great Depression-era skyscraper remains a top tourist attraction and one of the most photographed buildings in the world. Here are six facts you might not know about the longtime stalwart of 34th Street and Fifth Avenue in Manhattan.

The Empire State Building Was Built in 410 Days

The brainchild of financier John J. Raskob, the Empire State Building was conceived at a time when multiple developers were racing to leave their imprint on the New York City skyline — and it became a reality with mind-boggling speed. Fueled by the labor of as many as 3,400 daily workers, the structure climbed off the ground at a peak rate of 4.5 stories per week following its formal groundbreaking on March 17, 1930. Remarkably, the massive building — comprising 60,000 tons of steel, 200,000 cubic feet of Indiana limestone and granite, 730 tons of aluminum and stainless steel, and 10 million bricks — was completed ahead of schedule (and below budget) after just 410 days. President Herbert Hoover officially dedicated the new skyscraper on May 1, 1931.

The Empire State Building Was the Tallest Building in the World for Four Decades

Although it’s since been dwarfed by giants such as the United Arab Emirates’ 2,720-foot Burj Khalifa, the Empire State Building once set the standard for human ambition to reach for the skies. At 102 stories and 1,250 feet tall (not counting the later addition of an antenna, which added 204 feet), it was the first building to pass the 100-story mark, and its height easily surpassed the 1,046-foot record previously established by the Chrysler Tower in 1930. The Empire State Building remained the world’s tallest building until the 110-story Twin Towers of Lower Manhattan’s World Trade Center both pushed past 1,360 feet in the early 1970s.

The Empire State Building Has Its Own Zip Code

Since May 1980, with the designation of the skyscraper’s very own 10118 ZIP code, the Empire State Building’s tenants have enjoyed the postal privileges of a small city. This was the result of an effort to speed up mail delivery in Manhattan by giving higher-volume areas their own digits. Of the 63 new ZIP codes introduced in the borough that year, 39 were buildings that received at least 5,000 pieces of mail per day. The Empire State Building easily surpassed that cutoff with a daily intake of 35,000 pieces of mail.

The Building’s Colorful Light Displays Began in 1976

Among the Empire State Building’s famed features are the crowning lights that frequently change colors to honor cultural events, organizations, and local sports champions. The building first shone a beacon following Franklin D. Roosevelt’s presidential election in November 1932, but the multicolored displays that New Yorkers have come to know and love date back to the red, white, and blue bicentennial celebration of July 1976. The lights have since flashed in a range of colors, such as pink to commemorate Breast Cancer Awareness Month, blue for Frank Sinatra’s 1998 death, and even neon green in 2009 for the 25th anniversary of the first Teenage Mutant Ninja Turtles comic book. The building switched to LED lights in 2012, giving operators the ability to choose from 16 million colors and add special effects like ripples, sparkles, and strobes.

Competitors Race to the Top in the Annual Empire State Building Run-Up

For those with energy to burn (and maybe a masochistic bent), the Empire State Building Run-Up offers runners from around the world a chance to scale the majority of the skyscraper by foot. An annual tradition since 1978, the Run-Up covers 1,576 steps over 1,050 vertical feet, from the lobby to the 86th-floor observatory. The fastest record for what is billed as “the world’s first and most famous tower race” was set by Australian Paul Crake, who completed the grueling climb in nine minutes and 33 seconds in 2003. And while that’s obviously slower and more strenuous than the sub-minute it would take to ride an elevator, it does hold some appeal, given the lines to visit the observatory stretch the average elevator wait time to upwards of 45 minutes.

As one of the world’s most famous structures, the Empire State Building has made numerous appearances on the big screen. Just how many is impossible to determine, considering the number of low-budget films that fly under the radar, but the Empire State Building’s website once cited an estimate of “more than 250 movies.” The most famous ones include King Kong (1933), which features the titular ape swatting at planes from the newly completed skyscraper; Independence Day (1996), which sees the Empire State Building destroyed by a giant alien spaceship; Sleepless in Seattle (1993), which features an unforgettable meeting between the main characters in the film’s finale; and Andy Warhol’s Empire (1965), which focuses solely on the iconic building over the course of its eight-hour run time.

Milk plays a major part in human life — even for the most dedicated of vegans. Homo sapiens are biologically wired to be raised on our mother’s milk; the substance protects against short- and long-term illnesses while also sharing the mother’s antibodies with the newborn. Milk has also been the backbone of entire empires, and the substance even describes the very galaxy in which our planet resides. Here are seven amazing facts about milk (and its tasty plant-based alternatives) that’ll make you appreciate that carton in your fridge in a whole new way.

Milk Is Mostly Water

Although milk tastes much different than the H2O that comes out of the tap, the beverage is mostly water. Whole milk, for example, is 87% water, and the other 13% contains protein, fat, carbohydrates, vitamins, and minerals. Because of its high water content, milk is also a good hydration source during hot summer days. For all the talk of different milk types (whole, 2%, or skim), the difference in water content is only 3% at most.

Protein and Fat Content Is What Makes Milk White

Milk looks white because it’s reflecting all the wavelengths of visible light, and the combination of reflected colors creates white. The particles in milk — including the protein casein, calcium complexes, and fat globules — scatter light, much as light scattering on snow makes it appear white. Sometimes milk can have a slight yellow hue caused by a cow’s diet — the pigment carotene, found in carrots and other vegetables, can cause color variations — and the vitamin riboflavin can also cause a yellowish-green hue. Skim milk, which is low in fat content, can sometimes be a bluish color because casein scatters blue slightly more than red.

Humans Are the Only Mammals That Drink Another Animal’s Milk

Humans stand alone as the only mammals that drink the milk of another mammalian species. This is due to our history of animal husbandry, along with a genetic mutation that allows some humans to retain the enzyme lactase — which breaks down milk’s lactose sugar in the digestive system — beyond infancy. However, this mutation is not found in the majority of the 8 billion Homo sapiens on planet Earth — in fact, 68% of us experience some form of lactose malabsorption.

Although humans stand alone when it comes to mammals, some other species do drink milk from other animals. The red-billed oxpecker is known to steal milk from the udders of impala, and shorebirds such as seagulls have similarly swiped milk from the teats of elephant seals.

Milk Helped Build the Mongol Empire

The horse tribes of the Eurasian Steppes were one of the first cultures to adopt dairying, some 5,000 years ago. Because their vast plains weren’t fertile ground for agriculture, these nomadic tribes instead relied on animals and their milk for sustenance. Because they received much-needed calories from horse’s milk, these tribes could travel across land more quickly and maintain larger empires than their neighbors.

One of the remaining mysteries of milk’s importance in this era of human history is that 95% of Steppe people today lack the gene variant for digesting lactose, yet the population still gains a large portion of their calories from dairy products. One theory is that the microbiome found in the gut of Mongolians has somehow adapted to a millennia-long, dairy-heavy diet.

Dairy Milk Was Revolutionized by Bacteriology

In 1857, French chemist and microbiologist Louis Pasteur discovered that microorganisms in the air caused lactic acid fermentation, aka the souring of milk. Pasteur also discovered (after a request from Emperor of France Napoleon III) that certain microbes caused wine to go bad, but by briefly heating the libation to around 140 degrees Fahrenheit, those microbes died off, leaving behind a sterilized (or as it would be later known, “pasteurized”) liquid that would stay fresh for longer.

Pasteurization for milk wasn’t introduced until 1886, but it was a game-changer, as diseases introduced via contaminated milk killed scores of infants in the 19th century. With the introduction of pasteurization, that number dropped significantly.

Plant Milks Have Been Around for 5,000 Years

For years, dairy producers have sued alternative milk companies for using the word “milk” on their packaging — but history is not on their side. Evidence suggests that Romans had a complex understanding of the word “milk,” as the root of the word “lettuce” comes from “lact” (as in “lactate”). Many medieval cookbooks make reference to almond milk, and the earliest mention of soy milk can be found on a Chinese stone slab from around the first to third century CE. However, coconut milk has the longest history; archaeologists have recovered coconut graters among relics from Madagascar and Southeast Asia that date back to around 3000 to 1500 BCE.

Our Galaxy’s Name, “Milky Way,” Comes From a Greek Myth

The galaxy is home to hundreds of billions of stars, and stretches for truly mind-boggling distances. If you traveled the speed of light, it’d still take you 200,000 years just to cross its entirety. Its Western name — Milky Way — comes from a Greek myth in which the queen goddess Hera, while nursing the hero Heracles, pulled away her breast and sprayed her divine lactation across the cosmos. In fact, the root of the word “galaxy” is the Greek gála, meaning “milk.” The Romans also referred to the cosmos in Latin as Via Lactea, or “Road of Milk.” However, other cultures use different names to represent the great expanse of the starry sky. China, for example, calls it “銀河,” meaning “silver river,” and Sanskrit’s “Mandākinī” roughly means “unhurried.”
