In the face of tyranny, sometimes it pays to be a Paine in the neck. British-American political writer and propagandist Thomas Paine was born on this day in 1737. Paine is known for being one of the most influential voices during the American Revolution, but he was also a strong supporter of the French Revolution.
Paine was born in Norfolk, England, to a Quaker father and an Anglican mother, and had limited access to education in his early life. While his abilities to read, write, and perform basic arithmetic allowed him to work several jobs, he had few opportunities for economic advancement. Paine also seemed to struggle with every trade he attempted. One of his earliest jobs was being an officer of the excise, which involved chasing smugglers to collect excise taxes on tobacco and alcohol. The job paid little, and Paine was dismissed from the position after he published a pamphlet arguing that higher pay for excise officers would lead to lower corruption. Paine’s fortunes changed in 1774, when he had a chance meeting with Benjamin Franklin. Franklin urged Paine to move to America, and he arrived in Philadelphia, Pennsylvania, on November 30, 1774. There, he cut his teeth working at the Pennsylvania Magazine, owned by Franklin’s son-in-law, Robert Aitkin. During his tenure working with Aitkin, Paine published a number of articles under his own name and under pseudonyms. Being a steadfast abolitionist, Paine published African Slavery in America, an article that criticized and condemned the African slave trade.
Paine really began to make a name for himself when anti-British sentiment began to grow in the American colonies, along with calls for independence. In January, 1776, Paine anonymously published his most famous pamphlet, Common Sense, largely aimed at American colonists who were still undecided on the matter of independence. More than calling for sympathy, the pamphlet encouraged colonists to revolt against the British and to sever ties with the empire completely. Paine’s limited educational background might have actually contributed to his success. While his arguments were coherent and compelling, they appealed to a wider audience because of his tendency to speak and write in a plain, straightforward manner, forgoing the use of latin terms and phrases or philosophical allusions popular with more educated writers of the time. Upon being published, Common Sense sold 500,000 copies in a matter of months, and it was popular to read it aloud during public gatherings. Another popular pamphlet by Paine, The American Crisis, was published the same year, and it was promoted amongst American officers by George Washington himself. This pamphlet was aimed at bolstering the morale of the colonists as conflicts began to escalate in the American Revolution. It contained the now famous words, “These are the times that try men's souls: The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of his country; but he that stands it now, deserves the love and thanks of man and woman.”
Despite his staunch support for the American Revolution, Paine had few friends left by the end of it. When he returned to Britain in 1787 and wrote The Rights of Man in favor of the French Revolution, he was tried for treason, forcing him to flee to France, where he was imprisoned, ironically, for opposing the execution of King Louis XVI. Paine was released thanks to the American ambassador to France, but he later openly criticized George Washington for failing to support him when he had claimed American citizenship to avoid prison. He eventually returned to the former American colonies, now called the United States of America, at the invitation of President Thomas Jefferson. Paine died in 1809, and only six mourners attended his funeral. For much of the following century, Paine was remembered as an instigator and poorly regarded. Today, though, he’s remembered as a leading thinker and writer who helped embolden everyday Americans. No Paine, no American Revolution!

Leave your helmet at home! During a recent press conference, NFL Commissioner Roger Goodell announced that the league is considering a future in flag football. Flag football is nearly identical to American football, with one key difference: players aren’t allowed to touch each other. Instead, they were belts with three fabric flags on them, and pulling off one of the flags counts as a tackle. It’s a mainstay of P.E. classes across the U.S., but it actually has roots in WWII, when soldiers played this safer version of football as a way to pass the time during deployment. Eventually, the game made its way stateside, where Fort Meade hosted the first flag football game in the early 1940s. Despite its proud historical roots, the sport has never really caught on at the professional level. While flag football is gaining traction at the high school level, this is the first time that the NFL has discussed the possibility of a professional league. In fact, they’re considering two: one for men and another for women. NFL viewers have already been given a soft introduction via the Pro Bowl, which started featuring flag football in 2022. Although Goodell didn’t specify a timeline, he said that there is a significant amount of interest from both players and investors. No pain, no gain? No way.

This just might be the coolest dessert there is. As we kick off Black History Month, we're paying homage to Alfred L. Cralle, the Black American inventor who, on February 2, 1897, patented the ice cream scoop. Cralle was interested in mechanics from an early age and, after studying at Wayland Seminary in Washington, D.C., took jobs as a porter at a hotel and pharmacy in Pittsburgh, Pennsylvania. It was these jobs that inspired his most famous invention. Cralle saw firsthand how difficult it was to scoop ice cream one-handed, since it stuck to regular serving utensils. So, he developed a scoop with a built-in scraper to dislodge the ice cream easily, even with one hand. Such scoops are the standard in ice cream shops to this day. Cralle’s invention allowed for ice cream to be served faster, which undoubtedly helped it become one of the most important aspects of soda fountain culture in the early 20th century. It was from that culture that today’s featured food was born: the iconic sundae known as the banana split.
A banana split is an ice cream sundae traditionally made with three scoops of ice cream arranged between two halves of a banana. Toppings can vary, but usually include whipped cream, chopped walnuts or peanuts, chocolate syrup, caramel sauce, and diced strawberries or pineapple. The whipped cream is often topped with maraschino cherries.
Soda fountains played a big role in the banana split’s creation. Sometimes called candy kitchens or ice cream parlors, soda fountains evolved from early American pharmacies where pharmacists would compound, or mix, different medicinal ingredients together. Soda water was originally used in stomach-soothing tonics, with flavors added to cover up the taste of medicine. But soda soon became popular all on its own, especially when people started adding scoops of ice cream to carbonated drinks to create floats. From floats, loaded with toppings like whipped cream and chopped nuts, came sundaes—creations made entirely from ice cream in different configurations.
As for where exactly the banana split was invented and by whom, that’s a topic of heated debate. In fact, the towns of Latrobe, Pennsylvania, and Wilmington, Ohio, are both so sure that the banana split was created in their respective communities that they both hold festivals celebrating its supposedly local invention. Those in Latrobe claim that the split was invented by pharmacist David Strickler in 1904, after a young customer demanded “something different.” Strickler’s quick thinking in splitting a banana and making it into a decorative sundae served him well, as his invention became such a hit that he soon had to order custom-made glass serving bowls that could more easily accommodate bananas. Wilmington, on the other hand, attests that the banana split was invented by E.R. Hazard, a restaurateur who came up with the eye-catching, topping-heavy sundae in 1907 to attract college students to his restaurant. While most food historians feel that there’s more evidence for Latrobe—and Strickler’s—claim, we’ll never know for certain. There’s no doubt that banana splits would be a whole lot harder to scoop without Cralle’s invention, though!

Who said court documents had to be boring? Researchers recently translated writings on a 1,900-year-old piece of papyrus, and it has proven to be one of the oldest true crime documents in existence. The papyrus was originally found in the Judean Desert along with the Dead Sea Scrolls, and was recently rediscovered by researchers in a storeroom, after going overlooked for quite some time. It was originally marked as being written in Nabataean, an ancient Aramaic language, but when sifting through the piles of papyrus, researcher Hannah Cotton immediately recognized the labeling as erroneous. Indeed, the papyrus actually contained 133 lines of ancient Greek text, used by Romans to document court cases. One of the researchers said in a statement from the university, “This is the best-documented Roman court case from Judaea, apart from the trial of Jesus.” However, the document isn’t anything as grandiose as a religious text or a murder trial. Instead, it describes a Roman court case against Gadalias and Saulos, two would-be tax dodgers who allegedly tried to circumvent Roman laws. The case took place around 130 C.E., after the two forged documentation regarding the buying and selling of slaves. Tax laws aren’t fun regardless of what century you live in, but in ancient Rome, they could be a matter of life or death. The Roman Empire punished tax cheats with years of hard labor and even executed them on occasion. Interestingly, the papyrus was written by the prosecuting lawyer in the case, and the detailed document is giving historians insight into what legal proceedings looked like in ancient Rome and Roman-occupied territories. Unfortunately, much of the document is incomplete since portions of the papyrus were degraded over time. This case seems to have gone from solved to unsolved. If only true-crime podcasters had existed in ancient Rome.

It’s not exactly the same new wave of the 70s and 80s, but there is a new type of wave capturing the attention of scientists right now. Researchers at the Institute for Materials Research at Tohoku University, the Japan Atomic Energy Agency, and the RIKEN Center for Emergent Matter Science have discovered a new acoustic wave phenomenon, according to a paper published in Physical Review Letters. Surface acoustic waves (SAW) are waves that travel on the surface of a given material, and they’re used in a variety of electronic devices, especially for telecommunication. For example, they’re employed in frequency filters, which turn mechanical vibrations into electric signals and vice versa. Recently, researchers looked at how SAW would react as it passed through an array of nanoscale magnetic materials. They expected the waves to come out the other end in a symmetrical pattern. Instead, the array forced the waves to form an asymmetrical pattern, which they’re calling "nonreciprocal diffraction." They believe that this unexpected pattern is the result of how the magnetic materials interacted with SAW. This could be the first step toward manipulating SAW propagation, which could lead to applications in microwave communications and quantum engineering. How does that sound?

Six more weeks of winter weather! That’s what America’s most famous groundhog, Punxsutawney Phil, predicted just days ago. But even after Groundhog day, groundhogs themselves remain fascinating. These chunky creatures, once considered nothing more than pests to be exterminated, are finally being appreciated for the vital role they play in their ecosystems.
Groundhogs are, technically, a type of squirrel—just not the type that climb trees. They belong to the family Sciuridae, as do all squirrels, but they’re part of the genus Marmota, which includes 15 species of ground squirrels collectively known as marmots. Thus, groundhogs are sometimes simply referred to as marmots, and in some places they’re called woodchucks. No matter what you call them, though, groundhogs are extraordinarily resilient despite their small size. They only grow to be around 25 inches long, and typically weigh between 7 to 14 pounds, but their physical adaptations and tunnelling abilities allow them to escape from predators and endure harsh weather.
Groundhogs dig tunnels that can reach 50 feet in length. These tunnels have multiple openings and entrances, making it nearly impossible for predators to know where a groundhog will pop in or out. Many groundhogs live on open plains or in mountainous areas with harsh winters, but the temperatures in their underground tunnels remain more stable than those on the surface. This allows groundhogs to hunker down through harsh winter storms and gives them a safe place to hibernate. Speaking of hibernation, groundhogs’ chubby appearance isn’t the result of overeating—it’s yet another adaptation to help them endure the cold. Their extra layer of fat insulates their organs and supplies their bodies with nutrients during hibernation, which can last up to six months.
Until rather recently, groundhogs were considered pests due to their habit of tunneling under fields and gardens, eating vegetables as they go. Recently, though, ecological activists have launched public education campaigns to teach people about groundhogs’ more helpful habits. Their tunnels, for example, don’t just allow them to steal food; they also aerate the soil and deliver groundhog droppings directly into the dirt, helping it remain fertile. Whatever veggies they steal are really just a payment for their service.

Water those? Signs of water, of course! Using data and imagery from orbiters, scientists at the Natural History Museum in London have discovered clay mounds on Mars, and they’re proving to be some of the most convincing evidence yet that water once covered the red planet’s surface. The search for water on Mars has been going on for decades, but evidence for large bodies of it has been sparse. While Mars certainly had some water at one point, it’s been difficult to discern exactly how much. Now, scientists are pointing to mounds of Martian clay as evidence that, at one time, water was not only present but plentiful on the Red Planet. In all, around 15,000 clay mounds have been found covering an area roughly the size of Texas, and some of them are 1,600 feet tall. They contain clay minerals that could have only formed in the presence of running water.
Researcher Joe McNeil and his colleagues at the Natural History Museum in London used images collected by three separate orbiters: NASA's Mars Reconnaissance Orbiter, European Space Agency's Mars Express, and ExoMars Trace Gas Orbiter, which offered spectral composition data in addition to high-resolution images of the Martian surface. The data not only showed the presence of clay, but how much of it there was. Based on this, scientists estimate that the clay minerals were deposited between 3.7 and 4.2 billion years ago, when there were possibly oceans of water on the Red Planet. While the clay mounds indicate the presence of abundant water in the distant past, exactly how much of it there was and what parts of the planet it covered are still matters of debate. As McNeil said in a statement through the museum, "It's possible that this might have come from an ancient northern ocean on Mars, but this is an idea that's still controversial." Hopefully the clay mounds have more watery secrets to share.

While the clay mounds indicate the presence of abundant water in the distant past, exactly how much of it there was and what parts of the planet it covered are still matters of debate. As McNeil said in a statement through the museum, "It's possible that this might have come from an ancient northern ocean on Mars, but this is an idea that's still controversial." Hopefully the clay mounds have more watery secrets to share.

FREEWorld History Daily Curio #3024Free1 CQ
Throughout the centuries, history reminds us of a sobering fact: prejudice can make ordinary people do terrible things. Last week was the 80-year anniversary of the liberation of Auschwitz. But even before that particular concentration camp was built, the Nazi regime carried out a series of escalating, violent attacks against minorities in Germany and other occupied territories, often with the help of ordinary citizens. These attacks were spurred on by violent Nazi rhetoric, and were meant to terrorize Jewish people, LGBTQ people, political dissidents, and anyone else that the regime considered an “enemy.” Perhaps the most infamous of these attacks came to be known as Kristallnacht, or the Night of Broken Glass.
On November 7, 1938, 17-year-old Polish-German Jew Herschel Grynszpan shot German diplomat Ernst vom Rath in Paris, France. Grynszpan’s attack on the previously-obscure diplomat was motivated by the deportation of Polish Jews into “relocation camps” just weeks prior. Grynszpan’s family were among those taken to the camps. Vom Rath died a few days after he was shot, on November 9, when a Nazi gathering in Munich happened to be celebrating the anniversary of the Beer Hall Putsch, Hitler’s 1923 failed coup attempt. Chief propagandist Joseph Goebbels seized the opportunity to rile up outrage, using the news of Vom Rath’s death as a rallying cry for Nazi supporters. Goebbels called for violent action against the Jewish population of Germany and Austria, and Nazi officials spread the orders across their territories. Over the course of two nights, countless homes and businesses owned by Jewish families were vandalized or destroyed, leaving the streets littered with shards of broken glass and rubble. 30,000 Jewish men were arrested and sent to concentration camps at Sachsenhausen, Dachau, and Buchenwald, while around 100 Jews were murdered in the outbreak of violence. When news of the events reached the U.S., President Franklin D. Roosevelt condemned the violence and cut diplomatic ties with Germany, though the move wasn’t widely supported, as many in the U.S. favored a policy of appeasement. Kristallnacht was one of the Nazi Party’s first major steps toward the planned eradication of Jews and other minorities in Europe, and further legislative measures restricting their rights were passed in the following days and months. For the Nazis, propaganda was just another weapon to be put to violent use.Throughout the centuries, history reminds us of a sobering fact: prejudice can make ordinary people do terrible things.

Imagine picking up a reliable firearm and some candelabras at the same store. In 18th-century Russia, you might have been able to. After Peter the Great established an armory in the town of Tula, located to the south of Moscow, the area became renowned for fine metalworking, and not just when it came to armaments. The image above shows two candelabras from Tula made of steel. There are gilt decorations and beaded chains on each. The very artisans in Tula who made firearms also came to craft decorative metal objects for homes, known as “Tula ware.” Tula ware could include anything from jewelry boxes to end tables, all made from steel. The objects often mimicked the look of faceted stones and were meticulously detailed. Catherine the Great was known to be an avid patroness of Tula’s metalworkers, and Tula ware was often given as royal gifts to visiting dignitaries. Steel might be cheaper than gold, but craftsmanship can still make it a precious metal.
Pair of Candelabra, c. 1790–95, Cut and polished steel with gold and silvered decoration, 16 x 9.75 in. (40.7 x 24.8 cm.), The Cleveland Museum of Art, Cleveland, Ohio

FREETravel Daily Curio #3023Free1 CQ
Roughing it in nature can be fun...but there's nothing wrong with a few creature comforts along the way. Exploring the Alaskan wilderness is a daunting task, but in the Chugach and Tongass National Forests, there are cabins, or “huts”, to provide shelter for eager adventurers. Now, thanks to the Alaska Cabins Project, there will soon be even more stops for hut-to-hut hikers.
Currently, the U.S. Forest Service maintains around 200 cabins that provide much-needed shelter. Most of them were built in the 1920s to make the outdoors more accessible to less-experienced hikers and families, but the majority of them were built during President Franklin D. Roosevelt’s administration by the Civilian Conservation Corps (CCC), which was part of an initiative to give people more work opportunities during the Great Depression. The cabins are much like the famous Alps hut system, in Europe, where hikers, skiers, and other outdoor enthusiasts can book a hut for a day in France, Italy, or Switzerland. Many of the Alps huts offer food, lodging, and other amenities, though some are sparser, providing only limited provisions and a safe place to rest. Because of the huts, visitors to the Alps can carry lighter packs since they don’t need to worry about tents or carry as much food.
The cabins in Alaska are less hostel-like, but they are popular nonetheless, and many of them are reserved months in advance. They can be booked for an overnight stay, although other travelers are still allowed to stop in during the day. Some of Alaska’s cabins also offer canoes, boats, and other equipment that would be impractical for hikers to carry with them, allowing visitors to explore remote areas that would normally be out of reach. As part of the Alaska Cabins Project, the U.S. Forest Service is teaming up with the nonprofit National Forest Foundation (NFF) to repair 10 cabins and add 25 new ones to expand on the current trail system. The endeavor is the largest of its kind in 50 years. With new cabins, officials hope to alleviate some of the long wait times for reservations and make Alaska even more accessible. Exploring the outdoors doesn’t need to be so in-tents.
