WTF Fun Fact 13023 – The Samsung Butt Robot

Putting your phone in your back pocket is dangerous business (at least for the phone). So to ensure their materials were sturdy enough to withstand the crush, Samsung invented a robotic butt. The Samsung butt robot exerts 220 pounds of pressure on their phones during testing.

How Samsung phones are robot butt-tested

Clad in a pair of blue jeans, the butt repeatedly sits on phone to see how they’ll react to the common real-world beating their bound to take.

According to Tech Radar (cited below), whose writer was invited to tour the facility;

“On a recent trip to Korea, we were invited by Samsung to take a tour of its dedicated testing facility, and as we made our way through the company’s labs (each more diabolical than the last) we came to understand just how seriously the company takes its quality control – even if one of these tests does involve an undeniably quirky robot butt (dressed in blue denim jeans, no less) repeatedly sitting on handsets.”

Other Sumsung quality testing

The facility did a number of quality tests on their phones. They tested durability, sound quality, and battery power, among other important functions.

While we’re sure the phones still break from time to time, they have been through a lot. Tech Radar also reported:

“Using a number of different mechanical devices that look like the world’s most brutal skill testers (including auto drop testers, tumble testers and continuous free fall testers), Samsung’s handsets are repeatedly dropped from varying heights and angles onto a variety of hard surfaces, such as metal and marble.”

The butt test is still our favorite and when the first tech writers got a chance to see it around 2014, the company was met with so much public interest that they finally released a video so people could see it for themselves. Enjoy! — WTF fun facts

WTF Fun Fact 13022 – The World’s Fresh Water

Seventy-one percent of the Earth is covered in water, but that doesn’t mean we can use it all. But what percent of the world’s water is fresh (and therefore useable for humans to ingest)? Just 2.55 – and much of that is trapped in glaciers. Only 0.007% is available to us for use. The rest is saline and ocean-based. Interestingly, that’s roughly the same amount of freshwater that has always existed on Earth.

The world’s freshwater

Water is a valuable resource. If you’ve ever been without fresh water, even for a short time, you probably know exactly how panic-inducing a lack of fresh water can be. But for many people, fresh water is something we’ve always had and never really questioned. Those are the lucky minority.

It’s a bit startling to realize that the Earth’s freshwater resources have been around for hundreds of millions of years. What we drink has been recycled many, many times, whether it’s via the atmosphere or through our drinking water cups (and we’ll leave you to figure out how that works and then appreciate your local water treatment facility on your own).

Because we have very limited means of creating potable water out of saltwater through desalinization technology, it’s very hard to make enough new freshwater to sustain more humans. And that’s bad news when you think about how much water goes into things we enjoy – NatGeo says “the average hamburger takes 2,400 liters, or 630 gallons, of water to produce.

Fresh water keeps us alive

An increasingly large human population means we will need more water for hygiene, cooking, and drinking.

According to National Geographic (cited below): “Water scarcity is an abstract concept to many and a stark reality for others. It is the result of myriad environmental, political, economic, and social forces.” It has always been this way – people have fought wars over access to freshwater supplies for thousands of years.

“Due to geography, climate, engineering, regulation, and competition for resources, some regions seem relatively flush with freshwater, while others face drought and debilitating pollution. In much of the developing world, clean water is either hard to come by or a commodity that requires laborious work or significant currency to obtain,” they note.

WTF Fun Fact 13021 – The Scully Effect

The way we see scientists portrayed in books, movies, and television shows shapes the way we think about science in general. It also affects whether we can relate to the idea of being a scientist. This is especially important for women, who are underrepresented in most science fields. That’s part of what makes the Scully Effect so remarkable.

What is the Scully Effect?

Dana Scully was a character on the iconic television show The X Files. She was one of the first visible examples of a female scientist on a long-running television show. And it turns out that Gillian Anderson’s portrayal of the character changed the way viewers thought about the role of women in science.

According to a blog published by Westcoast Women in Engineering, Science, and Technology (WWEST) on Simon Fraser University’s website (cited below), “a phenomenon called ‘The Scully Effect’ has been anecdotally reported among fans of the TV show The X-Files and women in Science, Technology, Engineering, and Math (STEM) fields.”

In 2017, WWEST started a project called Media Depictions of Women in STEM “to evaluate how woman characters in STEM are depicted in popular media and how this might shape viewers’ ideas of women’s role in STEM (especially viewers in elementary and secondary school).”

They also reported that “a study by the Geena Davis Institute has examined just how much the character of Dana Scully has influenced girls and women to focus on STEM in their schooling and careers.”

What does the research show?

There were 2,021 participants in the study, in which :
– 63% of women who were familiar with Dana Scully said she increased their belief in the importance of STEM.
– 50% of those same women said Scully increased their interest in STEM.
– 43% of women who were medium to heavy viewers of The X-Files were influenced to consider working in STEM fields by Scully.
– 27% were convinced to actually study STEM.

Gillian Anderson said of “The Scully Effect”:

“At the time that Scully showed up [in 1993], we didn’t see that type of female represented very much at all out in the world of television, which is what we look to more and more as examples of who we are and to help make sense of us as human beings. And so, to suddenly have an appealing, intelligent, strong-minded female who was appreciated by her pretty cool male coworker was an awesome thing to behold, and I think that a lot of young women said, ‘That’s me. I’m interested in that. I want to do that. I want to be that.’”

Other research has shown that children tend to associate men with science around age seven due to cultural depictions of men in books, shows, and films. But when this can be prevented by also showing women as scientists, girls are more likely to believe that science is a general career path open to them as well. — WTF fun facts

WTF Fun Fact 13020 – Some of the World’s Oldest Advice

One of the oldest pieces of literature known to mankind is called the Instructions of Shuruppak, which contains some of the world’s oldest advice. This was found on the Abu Salabikh Tablet which was excavated in Central Babylonia (which is now southern Iraq). This Sumerian text has been dated to roughly the mid-third millennium BCE (2500 BCE).

Ancient advice via “wisdom literature”

The oldest recorded advice is written in the voice of a Sumerian king named Šuruppak to his son, Ziusudra. Some of it is similar to the biblical 10 Commandments, while other gems include how not to engage with prostitutes (in other words, a warning to lead a virtuous life) or act while drinking beer.

It begins:

“My son, I would instruct you,
Take my instructions,
Ziusudra, I would utter a word to you,
Give heed to it,
Do not neglect my instruction,
Do not transgress the word I uttered,
The father’s instructions, the precious,
Carry out diligently.”

The oldest fatherly advice

This ancient advice is only available to us in fragmentary form and (obviously) through translation. Still, it’s fascinating to see how much of it still applies, such as:

You should not locate a field on a road…
You should not place your house next to a public square: there is always a crowd there.
You should not loiter about where there is a quarrel; you should not let the quarrel make you a witness.
You should not steal anything…A thief is a lion, but after he has been caught, he will be a slave. My son, you should not commit robbery…
You should not speak improperly; later it will lay a trap for you.
You should not curse strongly: it rebounds on you.
My son, you should not use violence (?); ……. You should not commit rape on someone’s daughter; the courtyard will learn of it.
You should not boast in beer halls like a deceitful man.

It contains much more advice than this, which you can find here.

WTF Fun Fact 13019 – Surfing Invented By Ancient Polynesians

When was surfing invented? Probably 700 years ago, at least. The Polynesians invented surfing – that is, standing on a board while riding a wave – long before contact with European colonists. Only later did it come to Hawaii.

Who invented surfing?

Surfing goes back to at least the 12th century. Polynesians made the first surfboards from long pieces of wood. They likely used the activity as a means of transportation between the islands of Polynesia. But it was also a sacred activity and a way to train warriors.

Today, we typically think of Hawaii as the birthplace of surfing, but it likely originated on other Polynesian islands. The Polynesians brought it to Hawaii later.

According to the surf blog Errant Waves (cited below):

“Surfing was a central part of the power relationship on these islands. For example, the tribe with the highest rank had the best beaches and the best ‘boards.’ In addition, the chiefs of the tribes were the best surfers in the clan, who therefore were allowed to have the best boards made of the best wood. The ‘normal’ people were not allowed on the beaches of the tribal chiefs. They had to surf on their own, lesser beaches. Surfing was therefore literally a royal sport on these islands.”

While cave paintings tell us how old surfing may be, the earliest descriptions are in the notes of European colonists.

Colonists’ describe the invention of surfing

The first description of surfing on the island of Hawaii comes from the botanist onboard Captain Cook’s HMS Resolution. Joseph Banks wrote:

“(…) the shore was covered with pebbles and large stones; yet, in the midst of these breakers, were ten or twelve Indians swimming for their amusement: whenever a surf broke near them, they dived under it, and, to all appearance with infinite facility, rose again on the other side...At this wonderful scene we stood gazing for more than half an hour, during which time none of the swimmers attempted to come on shore, but seemed to enjoy their sport in the highest degree; we then proceeded in our journey, and late in the evening got back to the fort.”

Less than a decade later, in 1777, Dr. William Anderson wrote another description. In 1777, he published these words about surfers in Tahiti:

“I could not help concluding that this man felt the most supreme pleasure while he was driven on so fast and so smoothly by the sea; especially as, though the tents and ships were so near, he did not seem in the least to envy or even to take any notice of the crowds of his countrymen collected to view them as objects which were rare and curious. During my stay, two or three of the natives came up, who seemed to share his felicity, and always called out when there was an appearance of a favorable swell, as he sometimes missed it by his back being turned, and looking about for it. By then I understood that this exercise… was frequent among them; and they have probably more amusements of this sort which afford them at least as much pleasure as skating, which is the only of ours with whose effects I could compare it.” — WTF fun facts

WTF Fun Fact 13018 – Can Meditation Be Dangerous?

While we know various types of meditation can promote better mental and physical health, it’s easy to neglect the fact that just about anything can be dangerous if you don’t know how to do it right or aren’t prepared for it. But can meditation be dangerous?

In some cases, yes. But mostly for beginners who quit too early.

How can meditation be dangerous?

Dangerous is a loaded work, however, there are certainly some potential downsides to meditation. For those who are in a dark place or have multiple stressors that they have been repressing, harmful thoughts can sometimes arise during meditation. And if you aren’t skilled at pushing those thoughts away, it can cause you to ruminate on them even more.

According to Psychology Today (cited below), “The most profound interaction you experience in meditation is the interaction with yourself. As part of that, you would get in touch with buried and suppressed emotions. Meditation could trigger waves of anger, fear or jealousy, which had been sitting deep within you, and that would make you feel uncomfortable.”

Of course, having these emotions surface is likely good in the long term if it helps you deal with them and get past them. But if you stop meditating due to discomfort with those feelings, it can leave you worse off. (This is similar to starting and stopping therapy too soon – it can be uncomfortable at first, but that’s usually part of the process.)

The danger of being a beginner

If you’ve ever had a hard time meditating or found that you feel worse afterward, you’re not alone. But we tend to downplay the potential side effects for beginnings since there are so many potential benefits. And typically, the more you keep meditating, the better you get at it.

However, for those who have been through traumatic experiences, being left to meditate on their own with no other emotional support can be very challenging and can lead to poor mental health outcomes. You may need more than just meditation if you’re dealing with trauma.

Meditation beginners also sometimes misunderstand the idea of non-attachment and of letting their feelings go. Most techniques allow troublesome thoughts to come up and encourage you to acknowledge them and then push them away. But sometimes that can lead us to avoid truly dealing with these emotions in a way that will be productive in the long run.

While meditation seems to benefit many people, it’s not as easy as the internet makes it sound. Those dealing with trauma will probably want more personalized guidance and a support system as part of their meditation practice. — WTF fun facts

WTF Fun Fact 13017 – The Dementor Wasp

The dementor wasp sounds like a character from Harry Potter. But somehow it’s much worse (mostly because it’s real). These wasps can turn their prey into “zombies” before eating them alive. Isn’t nature wonderful?

Dementor wasp tactics

The Ampulex dementor is actually named after the soul-sucking Harry Potter characters, so you know they must have made a big impression.

The wasps have a pretty unconventional and gruesome way of preparing their prey for mealtime. First, they inject venom into their favorite snacks, cockroaches. And while you might not have a lot of sympathy for roaches, they do die in a pretty awful way.

The venom from the dementor wasp leaves them without control over their own bodies. That usually has the effect of forcing them to run right into their tormentor’s nest so that they can be eaten alive. The World Wildlife Fund said it rendered the roaches “passive zombies” in the process.

How do roaches turn into zombies?

According to the Washington Post (cited below), the WWF report states:

“Cockroach wasp venom blocks receptors of the neurotransmitter octopamine, which is involved in the initiation of spontaneous movement. With this blocked, the cockroach is still capable of movement, but is unable to direct its own body. Once the cockroach has lost control, the wasp drags its stupefied prey by the antennae to a safe shelter to devour it.”

Sounds like the stuff of nightmares.

Luckily, the wasps seem confined to just one place in the world – Thailand – and are pretty recognizable with their red and black bodies (not that the venom is enough to turn any of us into a zombie).

What’s in a name?

The Post also described the dementor wasp naming process:

“The Museum für Naturkunde, a natural history museum in Berlin, asked 300 visitors to pick the wasp’s name from among four options: ‘Bicolor,’ after its red-black pattern; ‘Mon,’ after a local ethnic group where the wasp lives; ‘Plagiator,’ since it mimics, or ‘plagiarizes,’ ants; and ‘Dementor,’ described to visitors as ‘magical beings, which can consume a person’s soul, leaving their victims as an empty but functional body without personality and emotions.'”

Frankly, the other options were pretty lame, and we doubt anyone was surprised people chose the Harry Potter-themed name. — WTF fun facts

WTF Fun Fact 13016 – Petting an Animal Reduces Stress

You’ve probably heard that petting an animal reduces stress. If you’re lucky, you’ve even experienced it firsthand. And if you have the pleasure of consistently getting some hands-on time with a furry companion (or even a pal’s pet), you may not always notice it, but you probably do have less cortisol in your system.

How does petting an animal reduce stress?

One of the most oft-cited studies about the animals reducing our stress comes from a study in the journal of the American Educational Research Assocation (AERA). It was a rigorous study that controlled for multiple other factors, such as overall health of the subjects. And it found that just 10 minutes of petting a cat or dog (many of which happened to come from a shelter and probably benefitted from some socialization) results in measurably smaller levels of cortisol, the hormone that regulates our flight-or-fight response.

The research was done on college students (who often get stressed out around midterms and finals). And one of the best parts was that even brief animal encounters could help reduce stress levels.

The researchers didn’t find the same effect when students viewed photos of pets or saw them in person – the real benefits came from physical contact.

Details of the study

The researchers collected saliva samples from 249 college students who participated in one of four types of animal encounters. (Cortisol levels can be measured using saliva.)

  • 73 students got to pet the cats and dogs
  • 62 watched other people pet the animals
  • 57 watched a slideshow of images of the same animals
  • 57 remained on the waitlist

Saliva samples were collected first thing in the morning and then two more samples were collected 15 and 25 minutes after the animal encounter.

Students with hands-on animal interactions had the lowest cortisol levels, though it didn’t necessarily last throughout the day. Still, even momentary stress relief can help regulate stress.

The researchers hope the knowledge that petting animals reduces stress will help colleges (and others) help people regulate stress before it causes more serious physical and psychological disorders. — WTF fun facts

WTF Fun Fact 13015 – The Great Wall Sticky Rice Connection

Walls between countries are more symbolic than anything, and that’s true for the Great Wall of China as well. Still, it’s such an epic structure that it took thousands of years to complete. It’s also not actually one long wall but a series of structures. Oh, and it’s held together by sticky rice.

What’s the story behind the Great Wall?

The first emperor of a unified China Qin Shi Huang Di began building the wall, but like many of his monumental structures, it was unfinished by the time of his death. In fact, it wasn’t until several hundred years later that the emperors of the Ming Dynasty (in the 14th – 17th centuries) took up the project again in earnest, building more sections along with the iconic gates and towers.

These emperors built hundreds of miles of the most famous section of the wall, which China has claimed is over 13,000 miles long – but likely includes sections that no longer exist (Chairman Mao encouraged people to take pieces of it to build their homes, for example). It’s a magnificent structure no matter its exact length, even if it didn’t always keep out invaders.

It is, however, held together with sticky rice.

Why sticky rice?

You might be confused if you’ve only had your rice cooked from the instructions on a package of Uncle Ben’s, but Chinese rice is deliciously sticky. It also helps make great mortar.

But don’t make fun of Chinese cuisine – sticky rice is just one part of the limestone mortar used to hold together this structure. This was discovered by scientists at Zhejiang University in China, and the recipe makes it the first example of composite mortar (something we all benefit from today whether we know it or not).

According to Smithsonian Magazine (cited below), the researchers “found that ‘sticky rice-lime mortar has more stable physical properties, has greater mechanical storage, and is more compatible, which make it a suitable restoration mortar for ancient masonry.’”

That makes sticky rice mortar one of the greatest and most enduring (literally) inventions of an already amazing lineage of governments. It is part of the reason structures built during this period are still around, surviving earthquakes and other tests from the elements.
