WTF Fun Fact 12718 – Crickets Can Tell You The Temperature

Let’s get one thing out of the way up front. While we call the method of measuring temperature using cricket chirps “Dolbear’s law,” the idea was first laid out in 1881 by Margarette W. Brooks. Her report “Influence of temperature on the chirp of the cricket” was published in Popular Science Monthly, it just wasn’t noticed until after Amos Dolbear published an 1897 article called “The Cricket as a Thermometer” 16 years later.

Regardless, it’s known as Dolber’s law, and it states that there is a connection between the air temperature and the rate at which crickets chirp. And it’s accurate for the field cricket within about 1 degree Fahrenheit.

It’s kind of like counting the seconds between lightning strikes and thunder, except way more inconvenient.

However, it is true that crickets chirp more speedily as the weather warms up. Dolbear realized this because crickets chirp consistently – that makes it possible to use the numbers in an equation.

In the original paper, Dolbear said you can get the approximate temperature in degrees Fahrenheit based on the times a cricket chirps in 1 minute – but you have to do some more math.

T_{F}=50+\left({\frac {N_{{60}}-40}{4}}\right).
In other words, T = 50+[(N-40)/4]
T = temperature
N = number of chirps per minute

If you want a shortcut for Celcius, you can use the number of chirps in 8 seconds and add 5.

Of course, there are many types of crickets, and Dolbear realized they each had a different rate of chirping. So he created new equations for other species. The problem for us is that we have to know which type of cricket we’re dealing with.

In fact, the common field cricket really isn’t the best cricket to use since its age, and whether it’s mating season can also affect the speed at which they chirp (so they’re not entirely consistent). But they’re probably good enough for a quick experiment. –WTF fun facts

WTF Fun Fact 12713 – da Vinci’s “Helicopter”

It’s hard to put into words the genius of Leonardo da Vinci. You have to look beyond his paintings and into his notebooks to see just how masterfully his brain worked. It’s like he understood the secrets of nature in a way no one else could (either then or now).

For example, in the 1480s, he was already imagining ways to create flying machines. And some might call his “aerial screw” the forerunner of the helicopter. That’s an innovation that it took us 400 more years to actually create!

(It’s only fair to mention that de Vinci’s drawing is not the first-ever of a helicopter-type vehicle. In 400 BCE, Chinese Taoist scholar Ge Hong described a “vertical flying machine” made of bamboo in the Baopuzi, though he was referring to a spinning toy. And since Chinese manuscripts made their way to Europe during the Renaissance, da Vinci was possibly influenced by this. It certainly influenced future helicopter inventors.)

Today, we even call the Renaissance artist’s invention “da Vinci’s helicopter” these days, and he wrote an entire treatise on flight. Just look at a page to see what he was capable of:

From: https://airandspace.si.edu/exhibitions/codex/codex.cfm#page-20-21

In the modern world, companies still bicker over who invented the first real helicopter, so it’s just more fun to give credit to da Vinci.

Of course, the aerial screw isn’t the same helicopter we have today. It’s not like he built a gas engine or anything, but he did conceive of a blade that would lift a vehicle vertically off the ground. His blades were not flat but shaped like a screw or helix.

As physicist Tom Hartsfield described in Big Think:

“What da Vinci lacked was the modern materials necessary to construct a lightweight and durable blade. He described the helical screw as being made of linen, with the pores stopped up by starch.

He also lacked the continuous motive power for such a machine. Men turning cranks could never dream of flying: they are far too heavy and too weak to produce enough power to lift themselves…Cognizant of this limitation, da Vinci envisioned a spring, wound by the crank turners, building up and storing energy. That built-up energy could be released in a quick unwinding burst, spinning the screw rotor. But as far as we know, such a device was never built.”  — WTF fun facts

WTF Fun Fact 12709 – The Josh Fight

It all started with a guy named Josh Swain who found a bunch of other Josh Swains on social media. Then it grew to encompass all Joshes. Now, anyone with a pool noodle and a good sense of humor can show up.

It’s The Josh Fight.

The Josh Fight is a now-annual event held in Lincoln, Nebraska (since that’s where the coordinates that the first Josh randomly picked out led people). The whole city is now in on the fun and the second annual The Josh Fight in 2022 had food trucks, games, and the traditional pool noodle fight. (Only soft, flexible pool noodles are allowed.)

Instead of getting out of hand in a bad way, the Joshes of the world really stepped up, crowning 5-year-old Josh Vinson Jr. as the Ultimate Josh. He returned to successfully defend his title.

According to Complex: “The event isn’t just for fun. With the pool noodle fight, the group raised almost $21K for Omaha’s Children’s Hospital and Medical Center. Some of those funds will be given to the Joshua Collinsworth Memorial Foundation. The Josh Cellars wine label also said it will match the same funds.”

WTF Fun Facts 12706 – Oxygen From The Ocean

It’s easy to think all our oxygen comes from trees on land – and a LOT of it does (especially rainforests, which there are lots of, and which need protection). But, in fact, most of it comes from the oceans.

That’s a bit harder to believe, but that doesn’t make it less true.

Plankton, specifically phytoplankton, produce most of the Earth’s oxygen. It also serves as food for sea creatures, but they don’t do much else that makes them interesting to most people. They just float around, completely at the mercy of the currents. They’re green and cruddy and you might even look at them and think “eww.”

And that’s fine since they also can’t be offended.

Here’s the deal: even though oceanic phytoplankton isn’t nearly as pretty as trees, it does similar work for us. These little organisms mostly float along the surface of the water or the upper part of the ocean where light still penetrates. They require sunlight to live and grow and produce food for other ocean creatures. They contain chlorophyll to capture the sunlight. If you remember back to grade school science, you probably see where this is going – photosynthesis.

Our oceanic phytoplankton turns the energy from sunlight, as well as carbon dioxide, and mineral salts partly into oxygen. There’s a lot of other stuff going on there too (other byproducts of photosynthesis, like the sugar they feed on), but oxygen is the byproduct we care about at the moment since we need it to breathe.

The cool thing is that even if you don’t live anywhere near an ocean, you still get the benefits because of the way the planet works. Oxygen is great because it just fills the atmosphere and doesn’t need to be shipped via trucks and planes to far-off destinations.

Scientists estimate that 50-80% of the oxygen production that takes place on Earth comes from the ocean. That’s a big range, but even if you go with the more conservative number, it’s clear that we can’t live without them. However, a lot of that oxygen also goes back into the ocean for other ocean life that needs it.

Don’t get us wrong, we love rainforests and regular trees too. But phytoplankton is doing more work than other flora when it comes to keeping breathing creatures alive.

We can do things like track plankton and get some readings off them, but it’s hard to know exact numbers of what they’re producing at any given time. The amount of oxygen they give off can change with the time of day or the time of year. It can also change depending on how healthy the oceans are.

One problem is that things like dead and decaying plants and animals in the ocean also consume oxygen when they decompose. That’s just one reason why killing off aquatic life (such as coral reefs) can be bad for us.

But if you remember one thing, it should be that these tiny, single-celled creatures do a lot of work for us by not only producing oxygen but by absorbing some of the CO2 we emit.

Some people call them “the lungs of the sea.” – WTF fun facts

WTF Fun Fact 12697 – Sharks Are Older Than Trees

Everything on Earth has evolved over millions of years to take its current form. So, in some sense, it can be hard to look back and make a firm division between a day when trees and sharks did and didn’t exist.

Still, there’s just really no comparison when you look at ever the more conservative numbers. Even if we go back to the species Archaeopteris, commonly considered the first species of “tree,” whose remains have been found in the Sahara desert, the now-extinct species “only” goes back 350 million years.

The numbers get kind of mind-blowing when you’re talking about evolution.

Sharks, on the other hand? Well, they go back 400 million years. And while that may seem like only a slight difference in number, 50 million years is A LOT of time (more than humans are really capable of conceiving).

We’re not sure which we would have guessed had come first – trees just seem older for some reason, but all evidence points to life starting in the oceans and not on the planet’s surface.

Sharks and trees aren’t something we compare very often, but both species have survived mass extinction events and hold secrets to the past that we can only dream of discovering.

WTF Fun Fact 12685 – A Pristine Forest In A Sinkhole

But there are 30 giant sinkholes throughout China, and explorers who rappelled down into one of them in May of 2022 discovered that nature was hiding something from us – a pristine, ancient forest. In fact, we know so little about this ecosystem that it would very well harbor wildlife we’re never seen before!

The sinkhole is 630 feet deep, 1,004 feet long, and 492 feet wide. Some of the trees inside the sinkhole are 130 feet tall!

While he was not involved in the expedition, George Veni, the executive director of the National Cave and Karst Research Institute (NCKRI) in the U.S, told Live Science more about these features:

“The discovery is no surprise, Veni told Live Science, because southern China is home to karst topography, a landscape prone to dramatic sinkholes and otherworldly caves. Karst landscapes are formed primarily by the dissolution of bedrock, Veni said. Rainwater, which is slightly acidic, picks up carbon dioxide as it runs through the soil, becoming more acidic. It then trickles, rushes and flows through cracks in the bedrock, slowly widening them into tunnels and voids. Over time, if a cave chamber gets large enough, the ceiling can gradually collapse, opening up huge sinkholes.”

He also said China was an ideal place to find sinkholes with something worthwhile inside: “So in China you have this incredibly visually spectacular karst with enormous sinkholes and giant cave entrances and so forth. In other parts of the world you walk out on the karst and you really don’t notice anything. Sinkholes might be quite subdued, only a meter or two in diameter. Cave entrances might be very small, so you have to squeeze your way into them.” 

The sinkhole is located in a UNESCO world heritage location in the Guangxi Zhuang Autonomous Region, near Ping’e village in the county of Leye.

While we don’t usually think of sinkholes as harboring anything special, this one surely did. These giant sinkholes are called a “tiankeng” in Mandarin, meaning “heavenly pit.” –  WTF fun fact

WTF Fun Fact 12684 – Pushed Into a Fortune

Some people come into our lives and make them richer. Other people barrel through our lives just because they’re rude and we’re in their way. For LaQuedra Edwards, it only took one person to do both.

In April of 2022, the Southern California woman was buying her weekly lottery ticket at a grocery store in Tarzana when “some rude person” (as she described them) bumped into her and didn’t even stop to say excuse me. That ended up pushing her into the machine as she was about to hit the button for the ticket she wanted. Except her finger veered off course due to the surprise and landed on the button for a $30 scratch-off.

She had already bought some other tickets and went out to her car, unhappy with the overall investment. But as many lottery players know, sometimes those cards end up paying for themselves.

Ms. Edwards $30 scratch-off DID pay for itself – and then some! She scratched it off to find she had won the lotto’s biggest prize, a whopping $10 million!

“I didn’t really believe it at first, but I got on the 405 freeway and kept looking down at [the ticket], and I almost crashed my car,” she said in a statement to the California Lottery. “I pulled over, looked at it again and again, scanned it with my app, and I just kept thinking this can’t be right.”

The odds of winning $10 million in that particular scratch-off game were 1 in 3 million! And while there are plenty of rude people out there who just keep on barreling through the lives of other folks, we almost have to wonder if this wasn’t some sort of “guardian angel.” (Or at least a fairy godmother in a rush.) –  WTF fun fact

WTF Fun Fact 12683 – From New Hampshire to Norway

Right before the pandemic closed schools, students at New Hampshire’s Rye Junior High School were working on a science project to launch a boat into the ocean with GPS attached to see where it would end up and what route it would take.

According to NPR: “Rye Junior High and the nonprofit Educational Passages — which says it aims to connect students around the world to the ocean and one another — started working together on the project in 2018, according to a release. The organization provided students with an assembly kit in 2020, though the construction and launch were complicated by the coronavirus pandemic.”

They thought it was lost when GPS stopped transmitting for a while, but eventually, it pinged again from a little uninhabited island off the coast of Norway. They just needed someone to retrieve it. Enter local sixth-grader, Karel Nuncic, who took a boat with his parents and puppy out to the island (which they could see from their coastal home) to recover the vessel. It wasn’t in great shape, but the hull containing artwork from the students who launched it was intact and dry.

In a Facebook post, the school said:

“RJH’s miniboat made it across the Atlantic! Our students put together a 5 foot drifter and had it launched into the middle of the Gulf Stream current on Oct. 25, 2020. Which way did it go? The onboard GPS recorded its location, most of the time. Then it went silent for a while. On Sunday, it pinged again and its location was on a small island off of Norway! Stayed tuned for more of the story! Here are the before and after photos of our miniboat and a map of its path. (Thanks to Educational Passages and The Clipper Foundation!)”
