Some names of inventions and ideas lead us to misunderstand their true nature. One notable misnomer is the koala 'bear,' which, despite its name, is actually a marsupial, not a bear. Another example is 'German' chocolate cake, a dessert that wasn’t invented in Germany but was created by an American named German. Perhaps the most impactful misnomer in history is when Christopher Columbus referred to the indigenous people of the Americas as 'Indians,' under the false belief that he had reached India.
While many of these misnomers are widely known and corrected, some still manage to deceive people even today.
10. The Battle of Bunker Hill

If you tour Boston’s historic landmarks, you might find yourself on Breed’s Hill, reading a plaque that claims it's the site of the Battle of Bunker Hill. How did the location of such a pivotal battle—where the iconic quote 'Don’t fire ’till you see the whites of their eyes' supposedly originated—end up being misidentified?
Before the battle took place, the colonists were indeed ordered to fortify Bunker Hill. However, Colonel Prescott's men chose to ignore that directive and instead fortified Breed’s Hill, which was lower and closer to the water. The exact reason behind this decision remains unclear, but it is believed they wanted a better position to aim their less-than-precise cannons. This change of location led to direct combat, and in just two hours, the battle became one of the bloodiest of the Revolutionary War.
In addition to Prescott’s last-minute decision, confusion was also caused by an incorrect British map that swapped the names of the two hills, further muddling the location of the battle.
To add to the misinformation, the famous 'whites of their eyes' quote isn't exactly accurate either. Variations of this line had been used years before the battle, but there's no evidence to suggest that any general actually uttered it during the fight.
9. The Big Bang

Astronomer Fred Hoyle coined the term ‘Big Bang,’ though he ironically opposed the theory he helped name. He used the term mockingly, referring to it as ‘a hot big bang’ during a radio interview in which he criticized it. The true originator of the idea was Georges Lemaitre, who aptly called it the ‘Primeval Atom,’ a much more accurate description of the concept.
The term ‘Big Bang’ is misleading because it doesn’t actually capture the essence of the theory. It wrongly suggests a colossal, noisy explosion that created the universe and everything within it. In reality, the theory proposes that all matter was once concentrated in a single point. After an initial expansion, the universe slowly grew and continues to expand. The initial burst wasn’t as vast as one might think—it took the matter from subatomic size to the size of a golf ball. While impressive, this is far from the dramatic blast we often envision.
There was no deafening ‘bang’ either. If we could somehow travel back in time to witness the event, we wouldn’t hear anything at all, since the frequencies produced by the expansion were too low for the human ear to detect.
8. Sago Palm

The sago palm (Cycas revolute), a popular houseplant, is actually not a true palm at all but a species of plant known as a cycad. This misconception frustrates botanists and horticulturists alike, but it’s important to note that cycads are arguably far more fascinating than ordinary palm trees.
Cycads, including the sago palm, have remained virtually unchanged for over 200 million years and even predate the dinosaurs. As a result, they’re often called ‘living fossils,’ and gardeners appreciate them as a kind of ancient relic in their gardens. While they may appear similar to palms, sago palms are only distantly related to them—much like how monkeys and sheep are both animals but vastly different species. The two diverged millions of years ago. In fact, cycad sago palms are more closely related to pine trees, as both reproduce through seed cones. Palms, in contrast, produce flowers and fruit instead of cones.
7. Pythagorean Theorem

Anyone who has studied geometry is familiar with Pythagoras’s famous theorem that relates the sides of a right triangle: A + B = C. Most of us believe that Pythagoras was the first to discover this principle, since it’s named after him. However, the Babylonians were already using the so-called Pythagorean Theorem over 1,000 years before Pythagoras was born. They even documented it on a tablet now known as Plimpton 322. Moreover, this mathematical concept wasn’t exclusive to the Babylonians; the ancient Egyptians, Chinese, and Indians all had their own versions of it centuries before Pythagoras.
Some argue that Pythagoras earned the credit because he was the first to prove the theorem, but there’s no solid evidence to support that he ever provided a proof. Pythagoras was known for being an eccentric who refused to let anyone record his teachings, so his ideas were never written down by his peers. Though he was well-known during his lifetime, it wasn’t until around 500 years after his death that he achieved the status of mathematical legend.
6. Lunatic

The word “lunatic” originates from the Latin term “luna,” meaning “moon.” In ancient times, it was believed that the phases of the moon, particularly the full moon, could trigger insanity or epilepsy in certain individuals.
Both Aristotle and Roman historian Pliny the Elder proposed that the brain's moisture made it sensitive to changes in the moon’s position, similar to how the moon affects tides. This idea persisted through the Middle Ages and likely influenced the belief that creatures like werewolves would appear during a full moon.
Though we now know that the moon has no effect on psychiatric or physical disorders, the term “lunatic” continues to be used. It was even included in official US federal laws until 2012, when Congress decided to update the terminology to more accurate and scientifically appropriate terms.
5. The God Particle

For those unfamiliar, the term 'God Particle' might suggest a singular subatomic particle responsible for explaining the universe's origins and resolving all our deepest questions. However, its true purpose is far less dramatic—at least for the casual observer. The God Particle, or rather its field, provides mass to other particles. For physicists, discovering this particle was a groundbreaking achievement as it confirmed the standard model of physics, ensuring the validity of existing theories.
The actual name of the particle is 'Higgs boson,' and it earned its more dramatic title as a marketing tactic. Physicist Leon Lederman, who wrote about the discovery, originally wanted to call it the 'Goddamn Particle' (since it was so elusive), but his editor persuaded him that using the more mysterious 'God Particle' would attract more readers. Surprisingly, the name stuck, much to the dismay of both scientists and religious figures.
4. Panama Hat

When visiting Panama, many tourists make sure to buy a genuine Panama hat. However, the one they’re likely purchasing is a replica, as real Panama hats are actually crafted in Ecuador.
In the mid-1800s, when these hats first gained popularity, few people traveled to Ecuador, as it was a remote location with little reason for travelers to visit. Panama, however, was a prime location due to its strategic position as the gateway between the Atlantic and Pacific Oceans. As a result, Ecuadorian artisans who created the montecristi hats began shipping their products to Panama for international trade. Unfortunately, they didn’t mark the hats with any indication of their Ecuadorian origin, leading people to mistakenly call them 'Panama hats' after the place where they were sold.
The misconception became even more widespread after President Theodore Roosevelt was famously photographed wearing one of these hats while overseeing the construction of the Panama Canal. The image quickly circulated globally, cementing the term 'Panama hat' in popular culture. From that point on, it became virtually impossible for them to be referred to as 'montecristis' or even 'Ecuador hats.'
3. Canary Islands

The Canary Islands, a group of islands located off the northwest coast of Africa, are famous for their sunny beaches and varied wildlife. Among the creatures found here are the yellow-green canary birds, native to the islands and abundant in numbers. These songbirds are so common and easy to spot that many people assume they are the source of the island chain's name. But as we now understand, names don't always align with expectations.
To uncover the true origin of the islands' name, we must travel back in time to A.D. 23–79 when the Romans first arrived. Upon their exploration, they were struck by the large packs of wild dogs roaming the islands. The presence of these dogs left such a strong impression that the Romans named the islands canaria insula, meaning “the island of wild dogs.” The term Canaria is derived from the Latin word canis, which translates to dog.
Following the Romans' departure, the islands faded from the radar of most outsiders until the 13th century. Despite this, the name “Canary Islands” stuck around. Dogs became such a symbol of the islands that they are even depicted on the official coat of arms of the Canary Islands.
As for the canary birds, their name actually originates from the islands they inhabit, not the other way around.
2. Global Warming

'Global warming' pertains to the average surface temperature across the globe. It doesn’t mean temperatures will rise everywhere, nor at the same rate. In fact, some regions could actually become colder. For instance, if the melting sea ice disrupts major ocean currents in the Atlantic—an event that seems likely—some areas, including North America and Western Europe, might face severe cold spells.
Climate change also brings about extreme weather conditions, including prolonged droughts or heavy rainfall, powerful hurricanes, Arctic chills, and other unpredictable shifts. It’s clear that it involves much more than a mere increase of a few degrees in temperature across the Earth’s surface.
The impact of climate change includes severe weather events, from massive storms to unexpected temperature drops, demonstrating the complexity of the issue. It’s about more than just a warm planet—it involves shifts in weather patterns, including mega hurricanes and intense cold fronts.
1. The Hundred Years’ War

Asking someone 'how long did the Hundred Years' War last?' may sound like a trick question, much like asking 'what color was George Washington’s white horse?' But, in fact, it’s a valid question, as the title of the war is somewhat deceiving. The Hundred Years' War lasted not 100 years, but 116. It wasn’t a continuous battle, but rather a series of intermittent conflicts.
In truth, the Hundred Years' War was a prolonged struggle between France and England that lasted from 1337 to 1453. During this time, the two nations were locked in disputes over land and royal claims. Due to multiple long truces, historians break the war into three distinct phases: the Edwardian, Caroline, and Lancastrian periods. Factoring in the times of peace, the fighting only lasted about 81 years.
There are other wars in history that lasted even longer, such as the Arauco War, which stretched for about 290 years. The 335 Years War may seem to outdo them both, but it lasted that long only because the opposing parties neglected to sign a peace treaty after halting hostilities 10 years into the conflict.
