A Perfectly Ordinary Date with a Terrible Reputation

Check your calendar. November 13, 2026, falls on a Friday.

For some people, that means avoiding ladders, black cats, important decisions, and possibly leaving the house altogether.

But how did an ordinary date become such a notorious troublemaker?

The number 13 has carried an unlucky reputation in parts of Western culture for centuries. One explanation involves the Last Supper, where Jesus and his twelve apostles made thirteen people at the table. Friday also acquired negative associations through Christian traditions surrounding the crucifixion.

Norse mythology offers another possible influence. In one famous tale, Loki arrives as an uninvited guest at a gathering of gods, leading to the death of Baldr.

Exactly when Friday and the number 13 became a single unlucky combination is less certain. References to the superstition appeared in nineteenth-century France, and it was firmly established in popular culture by the early twentieth century.

Not everyone was impressed.

In the 1880s, a New Yorker named William Fowler established the Thirteen Club specifically to challenge superstition. Members gathered in groups of thirteen, walked beneath ladders, and deliberately defied supposedly unlucky customs.

The club eventually attracted several future and former U.S. presidents.

Today, some hotels skip room 13, and some buildings omit a thirteenth-floor designation. Of course, the floor is still there. Changing the number on the elevator doesn't make an entire story disappear.

And the superstition isn't universal. In Italy, Friday the 17th has traditionally been considered unlucky, while in some Spanish-speaking cultures, Tuesday the 13th gets the blame.

As for November 13?

There's no scientific evidence that the date itself brings bad luck.

But if you spill your coffee that morning, at least you'll have someone to blame.

The Day Boston Was Swallowed by Something Sweet

On January 15, 1919, residents of Boston's North End heard a tremendous roar. A massive steel storage tank had burst, releasing approximately 2.3 million gallons of molasses into the streets.

And this was no leisurely trickle of syrup.

The resulting wave reportedly reached 15 feet high and traveled as fast as 35 miles per hour. Buildings were crushed, vehicles were swept aside, and an elevated railway structure was damaged. People and horses struggled desperately to escape the thick, sticky flood.

The disaster killed 21 people and injured approximately 150 others. Rescue workers faced an extraordinary challenge. The molasses clung to everything, making movement difficult and trapping victims beneath debris.

The tank had been leaking for years. Residents reportedly collected the escaping molasses in containers, and the company had painted the tank brown, helping conceal the leaks. Investigations eventually found serious problems with its construction and oversight.

Cleaning up was another monumental undertaking. Workers used saltwater, pumps, and considerable determination to remove the mess. For months afterward, the neighborhood reportedly smelled of molasses.

The tragedy helped drive changes in engineering oversight and safety standards.

It's one of those historical events that sounds invented, until you discover the photographs.

And suddenly, the expression slower than molasses takes on an entirely different meaning.

What Birds, Frogs, and Other Creatures Know Before We Do

Long before weather satellites and smartphone forecasts, people watched animals for clues about approaching storms.

Birds flying low meant rain was coming. Frogs croaking loudly suggested wet weather. Cows lying down supposedly meant you should bring an umbrella.

But do animals actually know something we don't?

Sometimes, yes.

Many animals can detect environmental changes that humans barely notice. One particularly useful signal is barometric pressure, which often drops as a storm approaches.

Researchers studying white-crowned sparrows discovered that falling air pressure stimulated the birds to eat more food. That makes sense for small birds that may have difficulty feeding during severe weather. Stocking up before a storm is a sensible survival strategy.

Frogs may also respond to changing atmospheric conditions. Some species increase their calling activity when pressure drops and rain becomes more likely. Since many frogs reproduce in water, rainfall can create favorable breeding conditions.

Birds can respond to changes in wind, temperature, and air pressure. Some species adjust their movements to avoid dangerous weather.

But what about cows lying down?

Despite its popularity, there's little convincing evidence that this familiar behavior reliably predicts rain. Cows lie down for many reasons, including resting and chewing their cud.

The important distinction is that animals aren't forecasting weather in the human sense. They're responding to physical changes in their surroundings, sometimes before those changes become obvious to us.

So if the birds suddenly behave differently, it might be worth checking the forecast.

If the dog refuses to go outside, however, you may simply have a dog who prefers napping on a rug over napping on dirt.

Sometimes the Best Discoveries Begin with “Well, That Wasn't Supposed to Happen”

Most inventions begin with a problem someone is determined to solve.

Others begin with a mistake, an unexpected result, or somebody's lunch.

Take penicillin.

In 1928, Alexander Fleming returned to his laboratory and discovered that mold had contaminated one of his bacterial cultures. Rather than simply throwing it away, he noticed something peculiar: bacteria weren't growing near the mold.

That observation eventually helped lead to the development of penicillin, transforming the treatment of bacterial infections.

Then there's the microwave oven.

In the 1940s, engineer Percy Spencer was working with radar equipment when he noticed that a candy bar in his pocket had melted. Curious about what had happened, he experimented with popcorn kernels and discovered that microwave energy could cook food.

His work eventually led to the microwave oven, although early commercial models were enormous and expensive. The first Radarange stood roughly six feet tall and weighed around 750 pounds.

Imagine trying to find counter space for that.

And finally, consider the humble Post-it Note.

In 1968, 3M scientist Spencer Silver developed an adhesive that wasn't particularly strong. It stuck to surfaces but could be removed easily. For someone trying to create a powerful adhesive, this was hardly a triumph.

Years later, fellow employee Art Fry realized the unusual glue could solve a problem: his bookmarks kept falling out of his church hymnal.

The resulting repositionable notes became one of the world's most familiar office supplies.

Three very different discoveries, all connected by one important quality.

Someone noticed an unexpected result and wondered what it might be good for.

Which suggests that the next time something goes wrong, it might be worth investigating before throwing it away.

Unless it's lunch. Some experiments are best left unfinished.

Eight Arms, Three Hearts, and a Remarkable Mind

Imagine having eight arms that can taste what they touch, three hearts, blue blood, and the ability to change your appearance in an instant.

Now imagine being smart enough to solve puzzles, open containers, and escape from places where humans have decided you should stay.

Welcome to the life of an octopus.

Octopuses possess approximately 500 million neurons, with a large proportion distributed throughout their arms. Those arms can process sensory information and coordinate movements with a degree of independence from the central brain.

This makes octopus intelligence remarkably different from our own.

In aquariums and research laboratories, octopuses have demonstrated impressive problem-solving abilities. They can manipulate objects, navigate mazes, and learn to open containers to reach food. Some have even been observed distinguishing between individual human caretakers.

Their camouflage abilities are equally extraordinary. Specialized cells in their skin allow them to change color and pattern rapidly, blending into rocks, coral, and sandy ocean floors. Some species can also alter the texture of their skin.

And then there are the escape artists.

Octopuses have soft bodies and no rigid skeleton, which means they can squeeze through surprisingly small openings. Their beaks, the only hard structures in their bodies, largely determine whether they'll fit.

An aquarium octopus that disappears from its tank may not have been stolen.

It may simply have decided to see what else is available.

With an animal this intelligent, perhaps we should stop asking whether it's capable of escaping and start wondering whether it's already planning the route.

The Original Menu Would Surprise Your Dinner Guests

Picture Thanksgiving dinner without mashed potatoes, cranberry sauce, green bean casserole, or pumpkin pie.

For many Americans, that sounds less like a holiday and more like a kitchen emergency.

But the famous 1621 harvest celebration shared by English colonists and the Wampanoag people looked considerably different from the Thanksgiving dinner we recognize today.

Historical accounts confirm that venison and wildfowl were served. Wampanoag hunters brought five deer, while the colonists had gathered birds for the celebration.

Turkey may have been among those birds, but nobody recorded a magnificent roasted turkey sitting in the center of the table.

The gathering lasted three days, and the food probably included other seasonal ingredients such as corn, squash, and possibly seafood.

Mashed potatoes? Not on the menu. Potatoes hadn't become part of the colonists' regular diet.

Pumpkin pie? Also missing. Pumpkins were available, but the colonists lacked the ingredients needed to prepare the familiar pastry.

And cranberry sauce? Although cranberries grew in the region, the sweetened sauce we associate with Thanksgiving appeared in written recipes decades later.

So how did turkey, potatoes, cranberries, and pumpkin pie become the stars of the holiday?

The menu evolved gradually as American food traditions developed. By the late eighteenth century, published cookbooks were pairing turkey with cranberry sauce. During the nineteenth century, Thanksgiving became increasingly associated with the elaborate family dinner.

Eventually, certain dishes became so firmly established that leaving them off the table could provoke a minor family rebellion.

Today's Thanksgiving meal is less a reproduction of one historical feast than a collection of traditions accumulated over centuries.

Which is probably just as well.

Explaining to your relatives that you've replaced the mashed potatoes with venison and boiled corn might not produce the holiday gratitude you were hoping for.
