WTF Fun Fact 13188 – Geckos Turn Off Sticky Feet

by

People have long wondered how geckos manage to stick to the sides of structures without falling off. The short answer is that they have sticky feet. But did you know geckos turn off sticky feet when they need to run faster?

How do geckos turn off sticky feet?

Geckos use toe hairs to turn the stickiness of their feet on and off. Oregon State University (OSU) discovered the details of this mechanism in 2014. They published their results in an article that appears in the Journal of Applied Physics.

The researchers noted that the geckos’ “adhesion system mechanism” has long been a curiosity. According to Science Daily (cited below):

“‘Since the time of the ancient Greeks, people have wondered how geckos are able to stick to walls — even Archimedes is known to have pondered this problem,’ said Alex Greaney, co-author and an assistant professor of engineering at OSU. ‘It was only very recently, in 2000, that Kellar Autumn and colleagues proved unequivocally that geckos stick using van der Waals forces.'”

Geckos have a system of hairs called “seta” on their toes. The seta can bend when they come into contact with rough surfaces in order to provide points of contact that keep the sticky surface of the gecko’s toe pads from adhering. Those hairs provide millions of points of contact to allow the creatures to maneuver over terrain without sticking.

Other insects and spiders also have this adhesion system. That’s why they can stick sideways to walls, seeming to defy gravity.

The stickiness system

Greany told Science Direct: “Understanding the subtleties of the process for switching stickiness on and off is groundbreaking. By using mathematical modeling, we’ve found a simple, but ingenious, mechanism allows the gecko to switch back and forth between being sticky or not. Geckos’ feet are by default nonsticky, and this stickiness is activated through application of a small shear force. Gecko adhesion can be thought of as the opposite of friction.”

The stickiness of geckos’ feet has long fascinated scientists seeking to produce material for use in adhesives. The ability of geckos to turn off sticky feet is yet another piece of the materials science puzzle that may come in handy someday in fields like construction and robotics. — WTF fun facts

WTF Fun Fact 13187 – Writing the Oxford English Dictionary

by

It’s no surprise that writing the first comprehensive dictionary (complete with linguistic and historical details) took many years. But writing the Oxford English Dictionary took many decades. To give you some perspective, it took the writers five years just to reach the word “ant.”

The history of writing the Oxford English Dictionary

The OED (as it’s abbreviated) project took a long time to get going. It all started in 1857 when members of the Philological Society of London decided that no current English dictionaries were acceptable and that they should spearhead the ultimate version. It wasn’t until 1879 that, according to the OED website (cited below) “the Society made an agreement with the Oxford University Press and James A. H. Murray to begin work on a New English Dictionary (as the Oxford English Dictionary was then known).”

The goal was to produce a 4-volume dictionary of roughly 6,400 words with every English word recorded from 1150 AD to the present. The writers estimated that the project would take 10 years.

However, after five years, the writers had just reached the word “ant” near the middle of the A section. There was a long way to go!

This was partly due to the level of detail necessary to trace the origins of words as well as their evolution. And since language never stops evolving, some work had to be redone during the writing of the Oxford English Dictionary. To this day it remains a “living document,” updated frequently.

The first part (or fascicle) of the OED was planned for an 1884 publication, but that didn’t quite work out. It would take an extra 30 years.

The dictionary required teamwork

As the team of writers grew larger, the work moved more quickly.

Murray directed a growing team and the last fascicle was published in April of 1928. Sadly, Murray did not live long enough to see the completion of the original OED since he died in 1915.

The final version of the OED was far larger than planned. It stretched to 400,000 words and phrases in 10 volumes (instead of the planned six). It continues to be updated to this day. — WTF fun facts

WTF Fun Fact 13186 – Medical Term for Ice Cream Headache

by

Eating ice cream too fast can hurt! In fact, so many people have experienced the phenomenon of these headaches (also called “brain freeze”) that there’s an official name for them. The medical term for ice cream headache is sphenopalatine ganglioneuralgia.

Why is there a medical term for ice cream headache?

The world loves ice cream. And sometimes we eat it too fast either because 1) it’s so delicious, or 2) we need to eat it before it melts. But we pay the price.

But what we sometimes call an ice cream headache is also referred to as “brain freeze” and can happen without the delicious ice cream.

According to the Cleveland Clinic (cited below), “Brain freeze is a brief but intense pain in the front part of your head. It occurs when you eat, drink or breathe something extremely cold…” So it can include breathing in freezing air as well as eating slushies, ice cubes, popsicles, etc.

While we have lots of colloquial names for the pain, the scientific/medical term for ice cream headache is sphenopalatine ganglioneuralgia.

Who is at risk for getting ice cream headaches?

Anyone can get a brain freeze. Children may be more likely to get brain freeze because they may not have learned to slow down when eating something fun like an ice pop.

Some research has shown that sphenopalatine ganglioneuralgia is more common in people who get migraine headaches.

What is sphenopalatine ganglioneuralgia?

An ice cream headache comes on quickly, but it also goes away relatively fast. It’s often gone in a few minutes, tops, and doesn’t need to be treated with medicine.

Brain freeze doesn’t cause other symptoms either – no nausea or sensitivity to light, for example. It’s just temporary pain that occurs “When your body senses sudden, extreme cold in the mouth or throat” and “tries to react and warm up.”

The headache sets in as “Blood vessels throughout the head expand to let extra blood into the area for warmth. That quick change in blood vessel size causes sudden pain.”

Of course, you can prevent the pain caused by doing that thing by avoiding that thing. But who wants to avoid ice cream and other cold treats? Instead, try warming up your mouth and throat by drinking room-temperature water or pressing your tongue against the roof of your mouth. Or just slow down on the ice cream. — WTF fun facts

WTF Fun Fact 13184 – People in India Read the Most

by

People in India spend 10 hours and 42 minutes a week reading, the most of any country on Earth. The U.S. makes up about 30% of the world’s book-buying population. But Americans don’t crack the top 5 for the time spent reading metric.

Where do most readers live? People in India read the most

India, Thailand, China, Phillippines, and Egypt round out the top 5 for the most time spent reading per person, on average, per week.

Data collected between 2017 and 2022 showed that:

  • India ranks first, with people spending 10 hours and 42 minutes reading per week (556.4 hours per year).
  • Thailand ranks second with weekly totals averaging 9 hours and 24 minutes (488.8 hours per year).
  • China readers average 8 hours a week (or 416 hours per year).
  • Those in the Philippines tend to read 7 hours and 36 minutes per week (395.2 per year.)
  • And Egyptians read for 7 hours and 30 minutes per week (or 390 minutes per year).

Books and their readers

Data collected between 2011 and 2020 shows that Americans love buying books (and they do read them, so it’s not just book hoarding). And most Americans do read books.

The World Population Review compiled numbers from various research studies and showed that while people in India read the most (in terms of hours spent reading):

Altogether, Americans read 275,232 books per year and makeup 30% of the market share of book buyers. A Pew Research Center study published in 2016 found that 72% of Americans had read a book the preceding year, a number that rose to 75% in 2022. But that rise was almost certainly due to the pandemic keeping people at home. In 2016 Americans read an average of 12 books a year (though 50% of the nation reads 4 or fewer, so we’re depending on some people to read a lot of books to make us look good). But we still tend to read more physical books than e-books, even though the e-book trend is growing in the U.S.

In other countries:

  • China reads 208,418 books on average per year (10% of all books purchased).
  • The United Kingdom reads about 188,000 books every year, and book sales have reached about 212 million!)
  • Japan makes up 7% of the market share for book buyers, and the Japanese read an average of 139,078 books per year. This makes up about 7% of the total market share.

What are the most popular books in the world? Well, you can probably guess – it’s the Holy Bible and the Holy Qu’ran. Next in line come The Harry Potter Series, The Quotations from Chairman Mao Tse Tung, and Lord of the Rings. Eclectic! — WTF fun facts

WTF Fun Fact 13183 – The Gruen Transfer

by

We’ve all fallen victim to the Gruen Transfer. In fact, stores, casinos, and malls are built around this theory in order to make us fall victim to it. The payoff is more spending on our part.

What is the Gruen Transfer?

Have you ever gone to a store and just started wandering around? Plenty of us can run in and out for what we need, but it’s hard to not start wandering occasionally, just to see if there’s anything else we might need or want. And that’s the whole point.

Marketers and designers specifically build floor plans and displays that disorient us and lure us in. It’s all designed to give us a general desire to keep shopping and looking at things. If you just go to Target for fun, you’re WAY deep into the Gruen Transfer.

According to Gizmodo (cited below): “The Gruen transfer is the idea that the shopping experience itself was worth doing, and that paying money for something not on any specific agendawasthe agenda.”

Of course, it’s all about getting you to consume more things.

Who was Victor Gruen?

The Gruen Transfer “mind trick” is named after architect Victor Gruen. But he’s probably rolling over in his grave since he hated the idea of disorienting consumers. His goal was to put items people needed in the same general location for convenience.

What his goal WASN’T was to confuse people and make them feel disoriented. In fact, Gizmodo’s article on the Gruen Effect (cited below) brings this to the fore, noting that “Gruen wasn’t a fan of the transfer at all. He railed against confusing, maddening stores that baffled consumers. In fact, his whole idea of a mall was based on efficiency on a very wide scale.”

“And, because there were only so many ways to design efficiently, many stores would be standardized. But Gruen wanted something more. Shopping places, he thought, should feature gardens, benches, cafes, and courtyards. It should be an experience. Then things like malls wouldn’t just be commercial zones, but would serve as public gathering places, where everyone, from every level of society, could mingle. He wanted to entice people, and get people to interact with each other, not confuse them.”

Making the transfer

Nevertheess, his name became associated with what the marketers and other designers did with his ideas. It became applicable within a store as well – such as a grocery store. Confusion reigns so you can see more things you might want to buy. The same is true of casinos. It’s easy for people to become disoriented, spend more time there, and part with more money.

Gruen just wanted public space for all. Now those places are ones where you can’t go to socialize anymore. You can only be there if you plan to shop.

As Gizmodo notes: “And so the guy who wanted to provide a public space, where everyone could get their shopping done so they could socialize, ended up inventing a system in which socialization equals shopping.” — WTF fun facts

WTF Fun Fact 13181 – Ray Bradbury’s Fahrenheit 451 Draft

by

The first draft of author Ray Bradbury’s Fahrenheit 451 was written on a rented coin-operated typewriter in 1953. It charged 10 cents for every 30 minutes. People estimate that the monetary cost of producing the draft was around $9.80.

What is Ray Bradbury’s Fahrenheit 451

You may have heard of the iconic dystopian novel in high school or college. At least, hopefully. If you’ve only heard about it in the news, chances are you’re not getting the full story (in more ways than one).

Bradbury wrote his novel during the Red Scare and McCarthy era, a time of ideological strife and oppression as the Nazis burned books and Americans threatened to. Some see connections between the current political climate and the one Bradbury wrote in, so the book occasionally comes up during political conversations. As with any book, it’s better to read it for yourself (and also know a bit about the precise context in which it was written since Bradbury was not commenting on 21st-century matters).

The author has given a few different motivations for his writing – fear of American book burnings, fear of mass media (specifically, the rise of radio and television) ruining our interest in literature, and government censorship. Again, these are all things we worry about today, but in a different context.

If you know anything about Bradbury himself, it can further complicate the reading of the book. He felt that political correctness was a form of censorship, but also abhored politics in general, especially in education.

Set in the distant future, the book is about “firemen” who are charged with burning any book they find. The main character eventually grows disenchanted and dedicates himself to the preservation of books.

Bradbury’s basement writing

Bradbury had great disdain for media consumption via radio, TV, and later the Internet. In his later years, he often encouraged students to “live in the library” instead. Unable to afford college, he educated himself at the Los Angeles Public Library. But he was also disappointed by their lack of science fiction literature.

Nevertheless, in the early 1950s, he worked in the basement at UCLA’s Powell Library. He had children at home, so needed a quiet place. It was there that he typed out the first draft (or novella version) of Fahrenheit 451. It was originally called “The Fireman.”

As for the title, according to Open Culture (cited below):

“When it came to finding the book’s title, however, supposedly the temperature at which books burn, not only did the library fail him, but so too did the university’s chemistry department. To learn the answer, and finish the book, Bradbury finally had to call the fire department.” — WTF fun facts

WTF Fun Fact 13180 – Hippopotomonstrosesquippedaliophobia

by

Hippopotomonstrosesquippedaliophobia is the fear of long words. And someone clearly had a sense of humor when they created it to be one of the longest words in the English dictionary.

What is hippopotomonstrosesquippedaliophobia?

Well, for starters, the tongue-twister isn’t officially recognized by the American Psychological Association’s DSM 5 (the Diagnostic and Statistical Manual of Mental Disorders, which is used to make diagnoses) as an actual phobia. It’s more of a curiosity and an excuse to show off your language skills.

One can also refer to the fear of long words as “sesquipedalophobia.”

But before you think it’s ridiculous, note that psychologists do categorize hippopotomonstrosesquippedaliophobia as a social phobia.

According to the DSM-5, criteria for social phobias require a patient to have the following:

  • a fear or anxiety about social situations where a person may be examined, like meeting new people or having a conversation
  • the fear or anxiety is disproportionate to the social situation
  • the fear or anxiety is persistent, and the social situation is excessively avoided
  • the fear, anxiety, or avoidance causes clinical distress

What causes such a unique phobia?

According to Healthline (cited below), social phobias like this can be associated with a negative event that was scary or traumatic at the time, a family history of phobias or other mental health issues, a person’s environment (especially if they see someone else develop a similar phobia), and changes in brain function. It’s certainly not something to make light of or ignore.

However, people may not seek treatment for fear of stigma, even from doctors. They’re more likely to take jobs or lead lifestyles that don’t require them to use long words. And there’s no official “limit” of word length that qualifies someone for this phobia.

The good news is that there are treatments and coping mechanisms one can explore with a professional to help someone afflicted with hippopotomonstrosesquippedaliophobia, whether it’s helping them manage anxiety symptoms or overcome their fear altogether with training.

WTF Fun Fact 13179 – Military Dolphins

by

Dolphins’ intelligence and biological sonar make them a valuable asset to many of the world’s military organizations, including the U.S. In fact, Naval Base Kitsap uses military dolphins to protect roughly 25% of the country’s nuclear stockpile.

What are U.S. military dolphins?

The dolphins are part of the U.S. Navy Marine Mammal Program, which used dolphins for the first time during Vietnam. The details of the program are secret. But we do know that both dolphins and sea lions are trained for different types of tasks. They’re used for recovery missions, defense tasks, and mine clearing.

At Naval Base Kitsap, the dolphins protect the harbor from weapons tethered to the ocean floor or buried beneath the sediment. Their innate sonar helps them detect these objects. They’ve been trained to return to their handler with a warning signal when they find one. Even more impressive is the fact that the trainer then gives the dolphin a tool (a buoy) to mark the spot where the weapon was found. That way, passing ships can avoid it, and Navy divers can dismantle it.

And when the threat is a human diver who means harm to the base, dolphins are trained to use their mouths to attach the buoy to them, which pulls them to the surface for capture.

Washington state’s nuclear dolphin protection

According to Military.com (cited below), “Since Bangor, Washington, now houses the largest single nuclear weapons site in the world, it needs protection from all sides, including the seaward side. That’s where the Navy’s dolphin pods and sea lions come in. Navy spokesman Chris Haley says the animals have been defending the waters around the stockpile, holding roughly 25% of the United States’ 9,962 nuclear warheads, since 2010.“

The former Soviet Union is believed to have trained dolphins for military purposes as well. The program is suspected to be ongoing in some sense. However, it’s also thought that much of it was sold to Iran during the fall Soviet regime. — WTF fun facts

WTF Fun Fact 13178 – The FBI and “Louie Louie”

by

Did you know there’s a connection between the FBI and the song “Louie Louie”? The FBI launched a criminal investigation into the Kingsmen’s song back in the mid-1960s to determine whether the lyrics were obscene. In fact, that investigation lasted two years!

The strange story of the FBI and “Louie Louie”

A letter from a concerned parent in 1964 asking to “stamp out this menace” of obscenity in music is one of many interesting pieces of the available-but-redacted FBI document on the song.

Of course, if you listen to the song, you’re likely to not understand any of the lyrics at all. They’re muddled at best and nonsensical even if you can make them out. But like so many musical conspiracy theorists, a handful of people thought they heard pornographic lyrics if they slowed the record down. The lyrics the complainants came up with said a lot more about the complainers than the artists!

For the record, here are the actual lyrics to “Louie Louie”:

Louie, Louie,
me gotta go.
Louie, Louie,
me gotta go.

A fine little girl, she wait for me;
me catch a ship across the sea.
I sailed the ship all alone;
I never think I’ll make it home

Three nights and days we sailed the sea;
me think of girl constantly.
On the ship, I dream she there;
I smell the rose, in her hair.

Louie, Louie,
me gotta go.
Louie, Louie,
me gotta go.

A fine little girl, she wait for me;
me catch a ship across the sea.
I sailed the ship all alone;
I never think I’ll make it home

Three nights and days we sailed the sea;
me think of girl constantly.
On the ship, I dream she there;
I smell the rose, in her hair.

Nothing obscene there!

Closing the investigation

The FBI never contacted singer Jack Ely during the two years of the FBI investigation. In fact, they closed the case saying: “, the man who sang the words of the song in the first place. At the end of the two years, the FBI didn’t even exonerate “Louie Louie,” they simply said that “the lyrics of the song on this record was not definitely determined by this Laboratory examination, it was not possible to determine whether this recording is obscene.” —WTF fun facts
