WTF Fun Fact 12767 – Lyrebird Mimicry

by

There are actually two types of lyrebirds, both live in Australia, and both are fabulous mimics. We just think the superb lyrebird has a better name. The other one is called Albert’s lyrebird and it’s a little less showy (but equally capable of mimicry).

Lyrebird taxonomy

The superb lyrebird belongs to the genus Menura (family Menuridae, order Passeriformes, if you like to get truly taxonomic). The birds live in the forests of southeastern Australia and do not fly – they are groundbirds.

For the most part, they’re not so impressive to look at. They look a lot like brown chickens. Well, except for the male superb lyrebird – he has to show off to attract females.

What does a lyrebird look like?

According to Britannica (cited below), “the male’s tail consists of eight pairs of ornate feathers, which resemble a lyre when erect. There are six pairs of filmy whitish feathers. One pair of 60–75-cm (24–30-inch) feathers that form the arms of the ‘lyre’ are broad and curled at the tip and are silvery on one side and marked with golden-brown crescents on the other. There are also two equally long ‘wires,’ narrow, stiff, slightly curved feathers that correspond to a lyre’s strings; they are situated in the centre of the curved ‘arms’…When the male displays in small clearings, which he makes at several places in the forest, he brings his tail forward so that the white plumes form a canopy over his head and the lyrelike feathers stand out to the side.”

Lyrebird mimicry

Here’s our favorite part of Britannica’s description: “In this position he sings, while prancing in rhythm, far-carrying melodious notes interspersed with perfect mimicry of other creatures and even of mechanical sounds.”

You might not think much of that at first, but the fact that a bird can mimic just about any sound is not only impressive but potentially creepy. Imagine walking through the deep forest in Australia (known for all manner of amazing-yet-terrifying creatures) only to hear the sound of a predator, a crying child, or a chainsaw!

We’d be freaked out, to say the least.

Seriously, listen to this bird mimic a baby crying!

Ok, now listen to construction noise (we had to double-check to make sure it was real):

Next time you head construction in the outback, look closer to the ground if you don’t see any men with tools. It may just be a lyrebird trying to troll you.

WTF Fun Fact 12766 – Hashtag Octothorpe

by

Hashtag, pound sign, number sign – call it what you will. This -> # <- is an octothorpe (or octothorp).

It’s not a word we had ever heard before, but it’s no surprise that signs we use quite frequently for many different purposes actually have proper original names.

The 14th-century octothorpe

According to Mental Floss, the sign originates in 14th-century Latin manuscripts when monks used it to abbreviate libra pondo (or the Latin term for weight in pounds). That would have been lb (like we use today), however “At the time, it was common to add a horizontal bar to abbreviations, known as a tittle, to show that the two letters were connected, and that the letter “l” was not the numeral 1.”

But as scribes began to write faster, the lb with a dash through the l began to look more like a # (in other words, a pound sign).

The octothorpe goes mainstream

No doubt a lot happened in between those Latin manuscripts and the # appearing on typewriter keyboards, but we haven’t found any proper explanation of how that happened.

However, when AT&T made its first phone keypads, it wanted them to be a perfect square. That would mean adding two more buttons. They chose * and # because they were already common on typewriters.

But why an octotherp, octothorpe/octothorp?

But when did the pound sign turn into an octothorpe? When an employee at Bell Labs decided to make up a name for the sign.

The thought process went like this, according to Google engineer Chris Messina’s history of the word:

  • There are eight points on the symbol so “OCTO” should be part of the name.
  • We need a few more letters or another syllable to make a noun, so what should that be? (Don MacPherson at this point in his life was active in a group that was trying to get JIM THORPE’s (ibid) Olympic medals returned from Sweden) The phrase THORPE would be unique, and people would not suspect he was making the word up if he called it an “OCTOTHORPE”.

The birth of the hashtag

Ok, so why and when did we start calling # a hashtag?

According to CBS News, it started with a Tweet.

“It all started back on Aug. 23, 2007 with a tweet by San Francisco techie and former Google developer Chris Messina. He wrote on Twitter, “How do you feel about using # (pound) for groups. As in #barcamp [msg]?”

People didn’t like the idea, but that clearly didn’t stop it from catching on.

Then, a few days later, another user named Stowe Boyd suggested the # symbol be called a hashtag.

And the rest, as they say, is #history.

WTF Fun Fact 12765 – The North Carolina Nuclear Bomb

by

The North Carolina nuclear bomb incident occurred around midnight on January 23/24, 1961.

Despite the potential for catastrophe, not many people know about the event. But when documents from the incident were declassified in 2013 after a Freedom of Information request, we found out just how close the U.S. came to suffering a self-inflicted nuclear disaster.

North Carolina Nuclear Bomb incident

Residents of the small farming town of Faro, North Carolina (near Goldsboro) awoke one night in 1961 to the sound of a B-52 bomber accident.

The Boeing B-52 Stratofortress broke up in the air, releasing the two 3–4-megaton Mark 39 nuclear bombs it was carrying. But dropping a bomb like this is different from having it explode. The nuclear payloads inside the bomb casings are what would have caused the major disaster and they had extra fail safes.

The plane

The plane was meeting up with a tanker for in-air refueling when the crew saw that it had a fuel leak in the right wing. Eventually, the pilot lost control of the rapidly leaking aircraft and ordered the crew to eject at 9000 feet. Unfortunately, two died in the crash, unable to parachute out, and one man died during his parachute landing. Five men survived.

The bombs then broke free of the aircraft and broke up roughly 1-2000 feet above the ground, releasing their payloads (but not activating them).

A very close call

In order for the payloads to detonate, the four arming mechanisms would have needed to break. In 2013, the US government released records showing that 3 out of the 4 mechanisms did fail, and one bomb had started to arm itself and charge its firing capacitors.

Only one functioning arming mechanism stood between North Carolina and a nuclear disaster. No one knows why the fourth mechanism stood up to the damage and failed to cause the explosion.

Remnants remain

The second bomb did not fully arm itself, but plunged into a muddy pit where it could not be recovered. All the military could do was remove the mechanism needed to detonate it and extract pieces of the bomb. Then, it covered the remaining parts with an easement, where it still sits today. – WTF fun facts

WTF Fun Fact 12764 – Mindfulness Meditation Changes the Brain

by

We need more large-scale studies to make definitive claims, but mindfulness meditation seems to have some cool cognitive benefits. In fact, we can see on brain scans that people who practice mindfulness meditation experience changes in their brains.

Minding your thoughts

Mindfulness practice encourages people to stop and spend time noticing their thoughts and then letting go of the ones that are negative, disorganized, or aren’t serving a positive purpose. It’s designed to help us notice and control our thinking. (As opposed to most meditation practices, which center around emptying the mind of thoughts.)

The part of the brain affected by mindfulness practice is called the amygdala. This is also called the “fight or flight” center because it is linked to fear and emotional responses. Brain scans have shown that mindfulness practice helps shrink the amygdala. While that may sound like a bad thing, an overactive amygdala can be bad for concentration, mood, and emotional regulation.

Regulating the amygdala

However, mindfulness has been shown to help increase the connections between the amygdala and prefrontal cortex. That’s a good thing because those connections help us regulate our emotional responses.

We need our amygdala, we just don’t want it to be hyperactive. And when we practice mindfulness, our bodies get better at regulating those emotional responses.

While some of the effects of mindfulness have been overstated in the press, there is evidence that it can modestly increase physical health and compassion and even reduce bias in addition to negative thought patterns.

The popularity of mindfulness meditation

A U.S. survey found that the percentage of adults practicing some type of mantra-based meditation,mindfulness meditation, or spiritual meditation in the previous year tripled between 2012 and 2017 (from 4.1% to 14.2%). Even among children (4 to 17 years of age), the percentage increased from less than 1% to over 5%. These emotional regulation techniques continue to grow in popularity.

Of course, there’s a lot we still don’t know about mindfulness and meditation in general, and they’re not always the best practices for everyone.

There are also different types of mindfulness meditation to practice, each with slightly different outcomes. For example, body scanning can help reduce negative thoughts. But practices in which participants are asked to observe their thoughts can sometimes lead to more negative thinking, especially among those who have just started practicing the skill and can’t let go of those thoughts easily.

In the end, it may be best for those who are new to mindfulness and observing their thoughts to do so with guidance from a teacher or tool so that they can stay on the right track and get the most out of their mindfulness practices. –WTF fun facts

WTF Fun Fact 12763 – The Harvard – Yale Prank

by

Every year, Ivy League universities Harvard University and Yale University meet up in a college football matchup that only alumni could possibly care about. (Yale has been bad for over a century, while Harvard has had a few eye-raising moments in the last few decades, but not enough to be a contender in the wider world of college football.)

The game is all about the rivalry, so pranks are fairly common. But a November 20, 2004 prank was at least good enough to make the evening sports news and go down as an embarrassment for Harvard.

Who carried out the Harvard – Yale prank?

Two Yale students from the class of ’05 named Michael Kai and David Aulicino gathered about 20 classmates to carry out the prank. The students dressed as members of the Harvard pep squad and handed out placards to the middle sideline section of Harvard fans. The idea was that when everyone held up the placards at the same time, it would spell out “Go Harvard.” At least that’s what the fans were told.

Impressively, they managed to hand out 1800 squares of paper, so it would have been hard for anyone to know what it was about to say (people only had small parts of letters).

Trolling their own team

Of course, now we know those placards didn’t spell out “Go Harvard.”

Instead, they spelled out “We Suck.”

The section was mostly full of alumni (which somehow makes it even funnier). The student section was off to the side, so the Harvard students couldn’t quite see it – and they later denied it even happened (despite the photo).

But Yale fans and players could see it, and so could that Harvard football team.

Prankster Dylan Davey didn’t feel bad about hoodwinking the alumni. According to the Yale Daily News (cited below):

“It was almost sad,” said Davey. “There were all these grandfather and grandmother types — and they all had big smiles, saying, ‘Oh you’re so cute, I’m so glad you’re doing this.’ I felt bad for about two minutes. Then I got over it.”

WTF Fun Fact 12762 – The Signing of the Declaration of Independence

by

When was the signing of the Declaration of Independence? Well, it’s far more likely that the document was signed on August 2, 1776, and not on July 4th as most of us are taught.

At the very least, August 2nd is when the signatures were done being added (though we’re also pretty sure the last one was added in 1777).

So, when was the Declaration of Independence’s signed?

The delegates to the Second Continental Congress voted to approve the Declaration of Independence on July 4, 1776. Out of the 13 colonies, 12 voted to approve, with only New York abstaining since its delegates had not yet received official permission from Albany yet. That’s because like much legislation, compromises were still being made until the last minute (around 86 changes to Thomas Jefferson’s original draft).

The document stated that the signatories would no longer be colonies of the Kingdom of Great Britain and would not be “free and independent States.” It’s likely that at this point, the secretary of the Continental Congress had his assistant create a copy to be printed, and then had it delivered to the Pennsylvania State House in Philadelphia (now known as Independence Hall) on August 2, 1776, where it was then signed (or the signatures were completed) by members of all the colonies.

(However, there is evidence that Thomas McKean didn’t have a chance to sign the document until after January 1777.)

Are you sure?

No one is exactly sure when the first signatures were added. But while Thomas Jefferson, Benjamin Franklin, and John Adams have all implied or stated that it was signed by Congress on July 4, 1776, the same day it was adopted, it appears that not even all the signatories were on site that day. That’s stated clearly by one of the signatories themselves. And to top it off, some of the signers hadn’t even been elected to the Congress by July 4th.

So, when was the Declaration of Independence signed? Maybe some people signed it on the 4th. But it’s far more likely that the final document was signed on August 2nd (and possibly done collecting signatures the following year).

Of course, this makes no real difference in the grand scheme of things. Independence Day celebrated the spirit of the document, which was largely in order and agreed to on July 4th.

But we do know one thing for certain about the Declaration of Independence – there is no treasure map on the back. – WTF fun facts

WTF Fun Fact 12761 – The 50-Star American Flag

by

Our current American flag was designed by teenager Robert Heft in 1958. This fact may give you a bit of pause for two reasons.

Who designed the American flag?

First, when we think of the designer of the U.S. flag, many of us think of Betsy Ross. And she is, indeed, the designer of the original. Of course, her design has endured as more states have been added to the Union.

But if you want to get technical, then The designer of the 50-star U.S. flag was a 17-year-old history student from Lancaster, Ohio named Robert Heft. He made it for a high school history project, and his teacher gave him a B- for lack of originality.

How did a teenager design the current American flag?

The second thing that might give you pause is that when Heft made his design, Hawaii and Alaska were not yet part of the United States. They didn’t even become part of the country at the same time.

Heft sewed on two more stars with the assumption that two more states would join. He used his parents then-current 48-star flag and his mother’s sewing machine.

According to the Ohio History Central (cited below), Heft’s history teacher “Stanley Pratt gave Heft a B- as the grade for the flag. Pratt supposedly stated that Heft’s design lacked originality, but the teacher did offer to raise the grade if Heft could get the flag accepted as the United States’ national flag. Heft sent his flag to Walter Moeller, his Ohio Congressman. Moeller succeeded in having Heft’s design adopted as the new United States flag on July 4, 1960.

Heft’s original flag has flown over the White House, every state capital building, and eighty-eight United States embassies. It remains in Heft’s possession, although numerous people and museums have offered to purchase the flag, including one offer of $350,000. Heft’s design was the twenty-seventh official flag of the United States.”

Heft died on December 12, 2009, in Saginaw, Michigan, of a heart attack. –WTF fun facts

WTF Fun Fact 12760 – 4th of July in Space

by

A 4th of July in space is certainly one to remember.

But space isn’t the first place we’d think of as an ideal place to celebrate America’s independence day. After all, the good hot dogs are down on Earth.

STS-4 mission astronauts TK Mattingly and Hank Hartsfield were the first astronauts to do it. It took 20 years of space flight for astronauts to be there on that day. Now, with the International Space Station almost always occupied, it’s quite common.

Space shuttle Columbia’s 4th of July in space

The first time it happened was on July 4, 1982

According to NASA (cited below): “That all changed with the STS-4 mission. On July 4, 1982, on the final day of their mission, astronauts Thomas K. ‘TK’ Mattingly and Henry W. “Hank” Hartsfield guided space shuttle Columbia to its first concrete runway landing at Edwards Air Force Base in California. President Ronald W. Reagan, who two years later instructed NASA to develop a space station, and First Lady Nancy Reagan greeted Mattingly and Hartsfield as they disembarked from Columbia. Shortly thereafter, the President led a celebration in front of space shuttle Enterprise, saying, “TK and Hank, you’ve just given the American people a Fourth of July present to remember.“ To cap off the event attended by 45,000 people and broadcast on television, President Reagan gave the signal for the Shuttle Carrier Aircraft carrying Challenger, NASA’s newest space shuttle orbiter, to take off to begin its transcontinental ferry flight to NASA’s Kennedy Space Center (KSC) in Florida.”

After that, Independence Day in space became more common.

Future Independence Days in space

NASA described future July 4th space flights: “Ten years passed before another crew celebrated the Fourth of July holiday in space. The seven astronauts of STS-50 had completed about half of their 14-day USML-1 mission on July 4, 1992, but the busy pace of the science flight allowed little time for celebrations. Three years later, 10 people orbited the Earth during the historic STS-71 first shuttle docking mission to the Mir space station. In fact, on July 4, 1995, space shuttle Atlantis undocked from Mir, returning NASA astronaut Norman E. Thagard and his two Russian cosmonaut colleagues from a three-month mission aboard Mir. By coincidence, for shuttle crew members Bonnie J. Dunbar and Ellen S. Baker, this marked their second Fourth of July in space as they both served on the STS-50 crew three years earlier. The day’s undocking activities left little time for celebrating, although Mission Control played “America the Beautiful” as the wake-up song that morning. To satisfy Thagard’s request, following their landing at KSC, ground teams treated him and his colleagues to some belated Fourth of July fare of hot dogs, hamburgers, and hot fudge sundaes.” – WTF fun facts

WTF Fun Fact 12759 – The Bayeux Tapestry

by

No one knows the exact origins of the Bayeux Tapestry. Our best guess is that it was commissioned in the 1070s, even though the first written reference to it wasn’t until 1476.

Hundreds of years later, this famous piece of medieval art was described in a cathedral treasury as “a very long and narrow hanging on which are embroidered figures and inscriptions comprising a representation of the conquest of England.”

And that’s precisely what it is. And when they say “very long,” they mean it’s over 200 feet long. That’s a lot of embroidering.

The Bayeux Tapestry

Historians believe the tapestry was commissioned by Bishop Odo of Bayeux, who was the half-brother of William the Conqueror. Some say it was created in Kent, England even though it eventually made its way to Bayeux, which is in Normandy, France. That’s where you can still find it today (though there’s a painstakingly-made replica at the British Museum.)

Britannica (cited below) describes the scenes: “The story begins with a prelude to Harold’s visit to Bosham on his way to Normandy (1064?) and ends with the flight of Harold’s English forces from Hastings (October 1066); originally, the story may have been taken further, but the end of the strip has perished. Along the top and the bottom run decorative borders with figures of animals, scenes from the fables of Aesop and Phaedrus, scenes from husbandry and the chase, and occasionally scenes related to the main pictorial narrative.”

Tapestry as history

The tapestry is considered a historical document. And we should be glad it’s safe – it has escaped destruction many times. According to Britannica:

“When first referred to (1476), the tapestry was used once a year to decorate the nave of the cathedral in Bayeux, France. There it was “discovered” by the French antiquarian and scholar Bernard de Montfaucon, who published the earliest complete reproduction of it in 1730. Having twice narrowly escaped destruction during the French Revolution, it was exhibited in Paris at Napoleon’s wish in 1803–04 and thereafter was in civil custody at Bayeux, except in 1871 (during the Franco-German War) and from September 1939 to March 1945 (during World War II).”

The Bayeux Tapestry is also the first depiction of Halley’s comet as well, which we know appeared in 1066 during the Norman Conquest. According to the Anglo-Saxon Chronicle, as William the Conqueror left for England, “a portent such as men had never seen before was seen in the heavens.”

It was considered bad luck at the time for the English King Harold II, who was defeated at the Battle of Hastings. – WTF fun facts
