Beehives

The first entry on the list goes to perhaps the most famous and finest example of animal architecture: the beehive. Built by incredibly industrious insects, beehives are among the most efficient structures in nature .

The regular hexagons provide the least-perimeter way to enclose infinitely many unit areas in the plane: the best way to separate the surface of their hives in equal parts all around, using the least possible total perimeter, thus reaching 100% efficiency in design.

If beehives aren’t the first thing that comes to mind when thinking about animal architecture, there’s a good chance you’re thinking of ant colonies.

Ants build the elaborate colony structure by hollowing out the area with their mandibles, grain by grain, without a blueprint, without a leader, and in total darkness . Unless the soil dries out dramatically, the chambers will keep their form.

These cute creatures excavate their homes by digging burrows into the ground, primarily in the Great Plains of North America. The region experiences extreme seasonal weather variations from season to season, requiring their homes to be built to withstand extreme temperatures, floods, and fires.

These underground "towns" have nursery rooms, pantries, living quarters, and temporary refuges —each smartly separated to serve a specific purpose.

Another famous animal architect, the beaver, uses felled trees to build dams . These dams create still ponds where beavers can construct their winter homes, called lodges.

These creatures prepare for winter by covering their lodge with a fresh coat of mud, which hardens to create a barrier against the cold and predators.

Caddisfly larvae construct protective cases using silk and whatever materials are available , such as sand, small stones, and plant debris.

These cases camouflage the larvae from predators and can be remarkably diverse in appearance, reflecting their creativity and resourcefulness.

Bagworms construct silk tents around themselves using bits of leaves, twigs, and other debris . These tents serve as mobile homes, providing protection as the insect feeds and grows.

Some species even camouflage their bags to blend into the environment, helping them avoid predators.

Coral reefs are massive structures built by tiny coral polyps. These marine architects secrete calcium carbonate to form hard skeletons, gradually creating vast and complex habitats for a myriad of marine species. They are often referred to as the "rainforests of the sea" due to their biodiversity.

Another famous architect from the animal kingdom, the spider, creates webs that serve as both homes and hunting tools . The silk used in these webs is incredibly strong, and different species produce a variety of designs, including sheets, orbs, and funnel shapes.

11

Swallow nest

Swallows build cup-shaped nests that can house entire colonies , using mud pellets, usually attached to vertical surfaces like cliffs or man-made structures.

The construction is precise and stable, providing protection for their young against predators and environmental elements.

As their name suggests, burrowing owls make their homes underground , often taking over burrows abandoned by prairie dogs or other mammals.

They use these subterranean homes to protect their young and hide from the heat of the day.

Smart boy

It's definitely not a secret that Albert Einstein was an exceptionally intelligent child. However, his achievements were extraordinary, and we're not just talking about him getting A's in school; he was teaching himself complex subjects as a preteen just for fun!

At just 12 years of age, his curious and powerful mind led him to become an autodidact. While other children were naturally playing on the playground, Einstein taught himself algebra and geometry in a single summer!

2

Scientific teen

That genius child became a teenage scientist. At 16 years old, most of us were dealing with high school, but Einstein was doing something a bit different: he was writing his first scientific paper, titled "On the Investigation of the State of the Ether in a Magnetic Field."

The paper was inspired by his compass and examined the force of magnetism. Although it wasn't published, this research reveals the passion, dedication, and great intellect that Einstein displayed from a very young age.

A hobby

But calculus and science weren't the only interests of the young Einstein. One of his other great passions was music. And, of course, he stood out in that field too.

It turns out that his mother, Pauline, was a talented pianist, and she encouraged Albert to play music from an early age. At 5 years old, Albert received a violin as a gift and began his lessons immediately.

It's said that, at first, he struggled a bit due to the instrument's complexity—yes, probably because he was only 5—but by the age of 13, he had become a skilled violinist, playing compositions by classical composers such as Bach and Mozart.

First job

Image: Andrew George

Einstein graduated from the Polytechnic Institute in Zurich in 1902 at the age of 23. Surprisingly, despite his impressive intellectual ability and broad knowledge, he was rejected for many of the academic positions he applied for after graduation. Faced with this situation, the scientist accepted a job at the Swiss Patent Office in Bern.

Later, Einstein stated that taking that job was "a salvation," as it provided a stable income and, at the same time, gave him free time to commit to his ongoing scientific research fully. Thanks to this key decision, by 1909, Einstein had already become a renowned scientist, celebrated for his contributions to physics.

Another passion

Image: Ian Keefe

With such a wonderful mind, it's no surprise that Einstein would have multiple and varied passions and hobbies.

One of those was sailing. Although he developed this interest as an adult, he was still very young when he discovered that sailing had a calming effect on him.

Sailing became one of his favorite activities, allowing him to escape the intensity of his work and appreciate nature—and his relationship with it—from a different perspective. He would often spend entire days on lakes and rivers, both during his time in Europe and later in the United States.

Almost a president

Image: Kate Macate

Among Einstein's varied accomplishments, there is one that many people don't know about: he almost became a president!

In 1952, the genius received a formal invitation from Israel to become the country's president. By that time, Albert was already a recognized and respected physicist, making him an ideal figure for that leadership role. However, Einstein politely declined the offer, claiming that he didn't have the political experience needed for the position and that his desire was to continue working in the scientific field. Once again, his wisdom stood out.

100 against him

Image: Igor Omilaev

Standing out in a field and introducing new ideas can often turn many against you. That "hate" we see today on social media isn't something entirely new. Some public figures had to deal with hate long before the internet became part of our daily lives.

Something like that happened to Einstein. As is well known, the publication of his Theory of Relativity brought a lot of uproar, both positive and negative. In 1931, a group of scientists published a collection of essays called One Hundred Authors Against Einstein (a bit aggressive, right?), in which they opposed the new ideas and discoveries of the German scientist.

Gossip

The 20th century had something for everyone. In the 1950s , while Einstein was immersed in his theoretical physics work, Hollywood was at one of its peaks, with stars like Audrey Hepburn, Elizabeth Taylor, Grace Kelly, and Marilyn Monroe gracing the screen. While it may seem that science and entertainment are separate realms, rumors and gossip brought these two worlds together.

Legend has it that our well-remembered scientist had a brief romantic affair with none other than Marilyn Monroe, one of the most talented and beautiful women the world has ever seen. Although it's true that both figures met at several public events in the United States, there's not enough evidence to support this rumor.

The marriage

Image: Marc A. Sporys

There is a romance involving Einstein that was somewhat controversial but definitely confirmed. We're talking about his second marriage.

Einstein was married twice in his life. In 1903, he tied the knot with Mileva Marić, his colleague at the Polytechnic Institute in Zurich, Switzerland. Just like him, she was also noted for her brilliance. After 16 years, the marriage began to weaken, and the couple divorced in 1919.

That same year, Einstein married for the second time, this time to his first cousin , Elsa Löwenthal. The marriage was controversial due to their familial connection, but the union lasted for 17 years, until Elsa's death in 1936.

We all have our fashion quirks, right? Some hate turtlenecks, others choose the quality of their shirts carefully, and others may pay attention to details like accessories.

It turns out that Albert Einstein also had a little quirk when it came to clothing, but it's probably not what you're expecting. In fact, Einstein didn’t pay much attention to clothes or fashion. However, there was one particular item he found totally annoying and useless: socks . It’s said that he often wore mismatched socks for several days in a row, and at one point, he simply stopped wearing socks altogether.

Georgia: No eating fried chicken with utensils

Image: Shourav Sheikh

In Gainesville, Georgia, it’s i llegal to eat fried chicken with a fork . This law, passed in 1961, was meant as a publicity stunt to promote the city’s status as the "poultry capital of the world."

While no one’s actually getting arrested for improper chicken consumption, a tourist was once jokingly "arrested" for breaking this law in 2009. If you visit Gainesville, just remember, fingers only!

2

Alabama: No stink bombs or confetti

Image: Damiano Lingauri

If you love a good prank or enjoy tossing confetti at celebrations, Mobile, Alabama, is not the place for you. The city has made it illegal to possess or use stink bombs , "funk balls," and anything designed to create unpleasant odors.

That’s not all, confetti and spray string are also outlawed, so don’t plan any glittery parades. Mobile prefers its air fresh and its sidewalks clean. We cannot blame them!

3

Arizona: No spitting in public

Image: Pete F

In Goodyear, Arizona, it’s not just bad manners to spit in public, it’s illegal. The law specifically bans spitting on sidewalks, roads, parks, and public buildings, and if you’re caught doing it, you could face a $2,500 fine or even six months in jail.

So, if you have a bad habit of spitting on the sidewalk , you might want to think twice before visiting Goodyear. Besides, it’s just gross!

Louisiana: No crawfish theft

Image: Rasmus Gundorff Sæderup

Think stealing crawfish is a minor offense? Not in Louisiana! Swiping someone’s crawfish , especially if the value exceeds $1,500, is taken so seriously that it can lead to a $3,000 fine or up to ten years in prison.

So, next time you’re enjoying a seafood boil in the Bayou State, make sure you’re not swiping from someone else’s plate!

Massachusetts: No dancing to the National Anthem

Image: Jeffrey F Lin

Patriotism is important, but nobody gets it like Massachusetts! In this state, a 1917 law makes it illegal to dance to the national anthem , though enforcing it would likely be a First Amendment nightmare.

It’s unclear why lawmakers felt the need to crack down on patriotic grooves, but to be safe, keep your hand over your heart and save the dancing for later!

6

South Carolina: No working (or dancing!) on Sundays

Image: Jess Bailey

Did you know that in South Carolina, you may technically have an excuse to skip work on Sundays?

An old law still on the books prohibits working on Sundays , though it’s rarely enforced. Strangely enough, dancing is also banned on Sundays. If you were hoping for a weekend filled with productivity and footloose fun, you might have to sit this one out!

7

North Dakota: No late-night fireworks

Image: Ray Hennessy

In Devil’s Lake, North Dakota, you can buy fireworks between December 26th and January 1st, but you can’t set them off after 11 p.m. What?

Let us explain: This law was originally passed for the millennium celebrations in 1999, but it’s still on the books today. Are you planning to ring in the New Year with a bang? Make sure you light those fireworks early or risk breaking the law!

Montana: No "folf" allowed

Image: Oskar Kadaksoo

Montana’s wide-open spaces might seem perfect for throwing a Frisbee, but in Helena, playing Frisbee golf (also known as "folf") outside of designated areas is illegal.

If you get caught, you could face a $500 fine or even six months in jail. Where are all these weird laws coming from, anyway?

Indiana: Black cats must wear bells on Friday the 13th

Image: Andreea Popa

Are you superstitious? You’ll love this one. In French Lick Springs, located in Indiana, black cats must wear bells around their necks on Friday the 13th.

This law was introduced in 1939 as a "war measure" to reduce stress among the public. While it’s unlikely anyone enforces this rule today, it’s still an amusing nod to old-school superstitions!

Hawaii: No billboards allowed

Image: Dennis Maliepaard

Ever notice that Hawaii’s landscapes are free of massive billboards ? That’s because billboards are banned statewide! The law, dating back to 1927, is part of an effort to preserve the state’s natural beauty.

Hawaii is one of the few places in the US where advertisements don’t compete with breathtaking ocean views. Now, that’s a law we can all enjoy!
