Though best known by the moniker Pocahontas, the woman who became one of the most famous Indigenous figures in American history was originally given two different names. 

She was born around 1596 to the Powhatan people of modern-day Virginia, who believed children should be given both a public-facing name and a private family name. Her public birth name was Amonute (the meaning of which is unknown), as recorded in the writings of English colonist William Strachey. Her private name was Matoax, sometimes written as Matoaka or Matoa. The meaning of this name also remains a mystery.

But she was also known to her people by the nickname “Pocahontas,” which roughly translates to “mischievous one” or “little wanton,” perhaps inspired by her playful demeanor. When English settlers arrived in 1607, the girl’s family kept both her formal names secret, based on a cultural superstition that anyone who learned your true name could cast a malicious spell on it. She was only known to the English (at least initially) as Pocahontas — a name she lived up to, as she was known to visit the English fort and cartwheel with the young boys.

People hated shopping carts when they were invented in 1937.

During the Great Depression in the 1930s, most Americans were just trying to get by, and few had the luxury of coming home from the grocery store with extra items. But that didn’t stop an Oklahoma grocer from coming up with the idea of a shopping cart, an invention that started out almost as disdained as it was practical.

The man behind the idea was Sylvan N. Goldman, owner of the Humpty Dumpty grocery chain. Interested in increasing his sales, he often paid close attention to how people shopped. One thing stood out: Customers would stop shopping once their handheld baskets got too heavy. Goldman started thinking: What if there were a way for shoppers to carry more with less effort? As an experiment, he took a folding chair, added wheels to the legs, and placed a basket on the seat. He then attached a platform between the chair’s supports to hold a second basket, creating a two-tiered cart that shoppers could push.

When he rolled out these new grocery carts in 1937, he expected a runaway hit, but the reaction wasn’t exactly enthusiastic. Women, already used to pushing strollers, weren’t eager to push another one at the store. Men, on the other hand, preferred not to push something stroller-like at all. To get people on board, Goldman got creative. He hired store greeters to hand shoppers a cart, and even paid actors to walk around shopping with them. Slowly, the idea caught on, and once it did, there was no going back.

Celibacy has been mandatory for popes and clergy for nearly 900 years, since the Second Lateran Council took place in 1139. Before that, several heads of the Catholic Church were family men: Seven popes were married before entering the priesthood, and at least 15 had children. 

Those married pontiffs included the very first pope, St. Peter, as well as St. Felix III (who served 483-492), St. Hormisdas (514-523), St. Agatho (678-681), Adrian II (867-872), John XVII (1003), and Clement IV (1265-1268).

Even before the Second Lateran Council, though, there were plenty of rules and regulations regarding the personal lives of Catholic leaders. The Council of Elvira in 306 decreed that a priest who sleeps with his wife the night before will be defrocked, while the 325 Council of Nicaea forbade priests from living with unmarried women. 

In 385, popes were forbidden from sleeping with their wives, and in 1045 Benedict IX (who held the papacy three tumultuous times) resigned — ostensibly in order to get married, though the fact that he sold the office to his godfather complicates the story. Several popes also had children outside of marriage, including Leo XII, Clement VII, and Innocent VIII, who was the first to openly acknowledge doing so.

George Washington never lived in Washington, D.C.

There are a lot of places named after George Washington, and he never lived in any of them — including Washington, D.C., which was established as the nation’s capital shortly after he became president. (D.C. replaced Philadelphia as the capital thanks to the Residence Act, which was passed on July 16, 1790.) 

Washington, the only U.S. president who never lived in the White House, had three different residences during his two terms in office from 1789 to 1797: the Samuel Osgood House and Alexander Macomb House in New York City and the President’s House in Philadelphia. Washington did pick the location of the White House, which was built between 1791 and 1800, but John Adams was the first to move in.

“I … take the liberty of requesting the favor of you to engage lodgings for me previous to my arrival [in New York City for the inauguration],” Washington wrote in a letter to James Madison in March 1789. “On the subject of lodgings I will frankly declare, I mean to go into none but hired ones — If these cannot be had tolerably convenient … I would take rooms in the most decent Tavern …” 
The Osgood House was the solution, and Congress rented it for him for $845 a year. Washington moved to the Macomb House — which was larger and overlooked the Hudson River — once it became vacant, but lived there for only six months in 1790 before moving to the Presidential Mansion. The latter appears to have been his favorite place to hang his hat while president, as he once described the three-story brick building as “the best single house in the city.”

Ancient Romans used concrete more durable than modern concrete.

The ancient Romans are known for many innovations that were ahead of their time, including running water and a rotating dining room. But some of the civilization’s construction work seems ahead of even our time. Case in point: Concrete used in some ancient Roman construction is much stronger than most modern concrete, surviving for millennia and getting stronger, not weaker, over time. Roman concrete endures even in seismically active regions and without reinforcement. The secret ingredient? The sea.

According to a recipe by Roman engineer Marcus Vitruvius from 30 BCE, builders mixed this ancient mortar with a combination of volcanic ash, lime, and seawater, poured it into wooden molds, then soaked it in additional seawater. This created a strong concrete suitable for dramatic structural designs. The material essentially reinforced itself over time, especially in, but not limited to, marine environments. Some 2,000-year-old sea walls, such as those lining the Italian coast, are near-indestructible, and the basic method has also kept walls in the Trajan’s Market archaeological complex standing since the second century CE.

As the ancient concrete ages, moisture dissolves volcanic ash and triggers a chemical reaction that causes small crystals to form. These crystals resemble materials that engineers add to concrete to toughen it up today, but because they develop naturally after the structure is already in place, they’re able to further bind the concrete together, particularly in porous areas that are usually weak.

Roman concrete is also more environmentally friendly than most modern cement — the key active ingredient in today’s concrete — which requires extremely high temperatures to create. The volcanic ash and similar compounds, collectively called pozzolan, bake at much lower temperatures, and the resulting crystals don’t require heat to form.

Edinburgh Castle, where Scottish monarchs lived for hundreds of years, sits atop an imposing rock outcropping called Castle Rock. Along with the Royal Mile, a hilly thoroughfare gently sloping down one side of the castle, it’s one of Scotland’s biggest tourist attractions. But for a long time, it was just an incredibly convenient rock, from a defensive standpoint, with sheer cliffs along three sides. Ancient people started using it in the Bronze Age, and flattened its top around 900 BCE. 

What those ancient people didn’t know is that hundreds of millions of years prior, that rock was the inside of a volcano. During the Carboniferous Period, roughly 340 million years ago, the volcano went dormant (and eventually extinct) and the magma inside solidified. That left what geologists call a volcanic plug, a rock formation that’s exceptionally sturdy and erosion-resistant — the perfect eventual location for a stronghold. As glaciers shaped the Scottish landscape, the sturdy dolomite plug stood steady as most of the sedimentary rock around it eroded away. Some of the sedimentary rock on the eastern side, now the Royal Mile, was protected by the plug.

Scottish tribes built a massive fortress atop Castle Rock in the late Roman era, which traded hands among the tribes a few times and eventually expanded into a more traditional castle in the Middle Ages. Today, the earliest building still standing dates to the 12th century. 

Letters are called ‘uppercase’ and ‘lowercase’ because of how printers stored them.

When you first learned to write, it may have seemed like the terms “uppercase” and “lowercase” referred simply to the fact that the letters existed in a big or small form in different contexts. But it turns out that the “case” here doesn’t mean something akin to “circumstance” or “condition.” Instead, the word refers to a literal case — the kind typesetters used for storage.

When the printing press came along in Europe in the 15th century, the pieces of movable type — the actual letters and other characters used for printing — were kept in shallow wooden trays, also known as cases. Capital letters were stored in the top case (the upper case), while small letters were stored lower down (the lower case) for more frequent use. Each tray was divided into compartments to hold the type; the lower case also generally held the punctuation marks and other pieces of type that weren’t letters, such as spaces. 

Today, of course, nobody keeps punctuation in a wooden tray beside a hand-operated printing press, but the terms stuck around long after the cases themselves disappeared. Every time you hit the caps lock key or toggle between uppercase and lowercase on your phone, you’re using a bit of printing shop vocabulary that dates back more than 500 years.

People used to vote by voice in colonial America.

Just because colonial Americans were subject to taxation without representation doesn’t mean they never voted. Indeed, elections were often held to select local officials and members of colonial legislatures. Rather than paper ballots, however, colonists voted by voice in a practice known as “viva voce.” This being the past and all, voting machines were centuries away from being invented, and paper ballots, despite having been around since ancient times, had yet to be widely adopted in the American colonies. So voters would gather in a public venue and announce their choice out loud for all to hear. 

Like most of the country’s early political traditions, viva voce came to America’s shores from the other side of the pond. It was the norm not only in Britain but also in the Netherlands, German provinces, and Scandinavia, eventually becoming law in six American colonies before also being adopted in Arkansas, Illinois, Kentucky, Missouri, Oregon, and Texas.

The public nature of viva voce was considered a feature rather than a bug because, as English philosopher and politician John Stuart Mill put it, “The voter is under an absolute moral obligation to consider the interest of the public, not his private advantage.” Old habits die hard, and viva voce persisted until the end of the 19th century. Fears that it was conducive to voter intimidation led to the current private ballot system, though not quickly. Five of the 33 U.S. states at the time still used viva voce in the 1850s, and nearly 10% of the votes in the 1860 presidential election won by Abraham Lincoln were cast by voice. The last holdout was Kentucky, which phased out the practice in 1891.

The Wright brothers’ first flight was shorter than the wingspan of a 747.

Orville and Wilbur Wright changed the course of human history when they took flight on December 17, 1903, in Kitty Hawk, North Carolina. But they didn’t make it very far. Orville’s maiden flight in the single-seat Wright Flyer lasted 12 seconds and covered a distance of 120 feet — shorter than the wingspan of a Boeing 747, which is between 195 and 224 feet depending on the exact model. 

The brothers took turns for their next three attempts in the aircraft (which was also known as the Kitty Hawk, Flyer I, and 1903 Flyer), reaching distances of 175 feet, 200 feet, and 852 feet, respectively, with the last of these flights lasting 59 seconds.

The Wright Flyer was simple in construction by modern standards, with a 12-horsepower engine, 40-foot wingspan, and weight of 605 pounds. The fateful day it took to the sky was the result of four years of planning, research, and development that saw many setbacks along the way — not to mention decades of inspiration. The Wright brothers first became interested in aviation in 1878, when their father gave them a rubber-band-powered toy helicopter that broke after little use but influenced them for the rest of their lives.

‘Teenagers’ didn’t exist until the 20th century.

For most of human history, you were either a child or an adult. The word “teenager” first entered the lexicon in 1913, appropriately enough, but it wasn’t until decades later that it took on its current significance. The ages spanning 13 to 19 are formative no matter what you call them, but three developments in the mid-20th century had a major influence on the creation of the modern teenager. 

The first was the move toward compulsory education, which got adolescents out of farms and factories and into high school, where they spent more time among their peers. The second was the economic boom that followed World War II, which created a new, highly sought-after demographic for companies and advertisers. And the third was the widespread adoption of cars among American families, which afforded 16-year-olds unprecedented independence.

Because one generation criticizing — and, to a certain extent, fearing — the next is a tale as old as time, not everyone was thrilled about this. In 1953, J. Edgar Hoover’s FBI published a report warning that “the nation can expect an appalling increase in the number of crimes that will be committed by teenagers in the years ahead.” Two years later, President Dwight D. Eisenhower called on Congress to pass legislation that would “assist the states in dealing with this nationwide problem” during his State of the Union address. But as anyone who’s ever been told “OK, boomer,” knows, the generation gap has yet to be bridged more than half a century later.
