      <video:title>The Bizarre Behaviour Of Rotating Bodies</video:title>
      <video:description>What you are looking at is known as the Dzhanibekov effect or the tennis racket theorem or the intermediate axis theorem.

It involves arguably the best mathematician alive, Soviet era secrets, and the end of the world.

So in 1985, cosmonaut Vladimir Dzhanibekov was tasked with saving the Soviet space station Salyut 7 which had completely shut down. The mission was so dramatic that the Russians made a movie out of it in 2017 and after rescuing the space station, Dzhanibekov unpacked supplies sent up from Earth which were locked down with a wing-nut and as the wing-nut spun off the bolt, he noticed something strange:

The wing-nut maintained its orientation for a short time, and then it flipped, 180 degrees. And as he kept watching, it flipped back a few seconds later and it continued flipping back and forth at regular intervals.

This motion wasn’t caused by forces or torques applied to the wing-nut: there were none. And yet it kept flipping. It was a strange and counterintuitive phenomenon. One that the Russians kept secret for 10 years.</video:description>

At the height of the Cold War, nuclear weapons were seen not only as devices of destruction, but also as tools for progress. Project Plowshare was a bold attempt to use atomic explosions for more practical purposes: from digging canals and creating harbors to reshaping entire landscapes. This project was designed to push the limits of what seemed possible, but instead turned into an environmental disaster.

How did Project Plowshare come up? What happened to it, and why did it fail in the end?

We’d love to thank some of the experts who helped us on this video.

Firstly, a huge thank you to Neil Smith for sharing his technical and historical knowledge of “The Thing” and operation Easy Chair. These devices are crazy complicated! And Neil (given that he’s actually built a working replica of “The Thing!”) gave invaluable insight into how it works, and detailed feedback on early versions of the video. You can see even a more detailed explanation of “The Thing” from Neil here – &quot;Leon Theremin Changed Spying FOREVER with this 1940s invention!&quot;, on his channel: @MachiningandMicrowaves 

Thanks to R. Paul Wilson for a comprehensive overview of the potential ways that credit cards and contactless payments can be compromised, and for connecting us with Christopher Forte. A big thank you to Christopher for his technical advice on different attack vectors for NFC transactions, his insights into the “cat and mouse game” between hackers and security providers, and feedback on different parts of the video.

Thanks to Pavel Zhovner, CEO of Flipper Devices, for talking us through the various security layers in NFC transactions, showing us round the Flipper HQ, and even giving us several Flippers to experiment and </video:description>

      <video:title>The 13 Trick</video:title>
      <video:description>Thanks, mom ❤️
This is a video I shared elsewhere a couple years ago before YouTube shorts could be more than a minute long. Today, they can&apos;t be more than 3 minutes, but with a few &apos;fast forwards&apos; I was able to get it just under the limit and finally share it here!

The &quot;13 Trick&quot; is a self-working mathematical card trick where aces = 1, jacks = 11, queens = 12, and kings = 13.</video:description>

      <video:description>I bought 10,000 shade balls and tried to swim in them. 

They appear to act like a non-Newtonian fluid: rigid under high shear stress, but they flow like a liquid under low shear.</video:description>

      <video:title>Testing the US Military’s worst idea</video:title>
      <video:description>Rods from God.

This is the nickname for a theoretical space weapon, in which large rods of tungsten would be dropped onto Earth based targets. 

The idea behind this weapon is that the projectiles would build up enough speed, and thus kinetic energy, which would cause bomb-like destruction on the ground below. 

The concept was devised during the Cold War but has faced heavy criticism both logistically and scientifically.

However, it has certainly made its mark on science fiction, both appearing in and being referenced across many media, from TV to video games.

But could it work in practice? 

We tested to find out.</video:description>

      <video:description>I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they&apos;re there. 

The first time I heard about shade balls the claim was they reduce evaporation. 

But it turns out this isn&apos;t the reason they were introduced.</video:description>

      <video:title>Why do planes fly so high?</video:title>
      <video:description>Now, it’s true that one of the benefits of flying at 30,000 ft is a smoother ride. This is high in the troposphere, the layer in which most weather occurs. So, there’s less turbulence and fewer storms to navigate around.

But this is not the main reason that planes fly so high.</video:description>

Correction: From construction images of Citicorp, sharp-eyed viewers might see that the mid-V columns are still there. Those columns help prevent buckling of the diagonal and the weight of people on the floor above, but do not take the majority of the gravity load. So we left them out of our diagram to clearly explain the load paths. See page 70 of this source for more details - https://drive.google.com/file/d/1ODFo66-_V7Y9vKANbj53mQ0z20RZ2Uai/view

A big thank you to our guide, Ciro. We paid full price for the tour, and are grateful he and his father Gaetano agreed to let me film and share a bit of what we learned. (The video was approved by Gaetano before releasing.) There is FAR more to see at Pompeii than I show in this video. We were very happy with our experience and found Ciro to be very professional and patient with our questions. You can book your own personal tour of Pompeii with Ciro or Gaetano at their website. https://www.pompeiitourguide.com/

      <video:title>How Disc Golf Discs Are Made (MVP Manufacturing Tour) - Smarter Every Day 301</video:title>
      <video:description>The coolest part about this is that Brad and Chad didn&apos;t ask me to say anything in particular.... they partner with wholesale dealers so you should be able to find them at your local disc golf store.  If you&apos;d like to explore what they make you can check out their website here. https://mvpdiscsports.com/ You can also find their products on Amazon, just look up &quot;MVP Discs&quot;

If you&apos;ve never played disc golf and you want to own your own discs, I recommend getting their 3 disc starter set off of Amazon. Their Amazon page is here: https://www.amazon.com/stores/MVPDiscSports/page/36E7BB9F-BB13-4144-8655-22EC73E8C4F1?ref_=ast_bln&amp;store_ref=bl_ast_dp_brandLogo_sto

What Disc Golf topics should we explore with MVP?

      <video:description>Here&apos;s that link for Ridge! https://www.ridge.com/smarter

Do you think all the frequencies are happening on this one mechanical device, or do you think there are multiple animals making the call at different frequencies?  I&apos;m leaning towards the wobbles being the higher pitch sounds, and the &quot;progressive buckling&quot; being the lower pitch sound..  I think it would be SO cool to partner up with someone and write a paper on this. 

On the Ridge Wallet.... I worked it out with Ridge so you can get a free airtag money clip on orders over $76.  They were cool and said yes. If you enjoy yours half as much as I enjoy mine it&apos;s worth it. Here&apos;s that link: https://www.ridge.com/smarter !  Thanks for considering supporting the sponsor!

In 2018, Marshall Space Flight Center uploaded a ton of really cool old &quot;Saturn V Quarterly Updates&quot;.  Watching these videos really helped me understand the scale of the Apollo program.  What our ancestors did was absolutely amazing.  Here is one of those videos: https://www.youtube.com/watch?v=zGtU3vnNeEk

Go to the MSFC YouTube channel, scroll back to 2018 and watch those Archival films.  They are amazing, even from a film production standpoint.

      <video:title>This Parasite Won’t Die</video:title>
      <video:description>Malaria has killed humans for millennia. From DDT to bed nets, vaccines, and genetically modified mosquitoes, we’ve pushed back... but resistance and climate change threaten progress. The war isn’t over.

      <video:description>Cocaine can make you feel powerful and euphoric in seconds, but it hijacks your brain’s reward system and strains your heart. Here’s what really happens inside your body when you take it.

Losing weight is hard, and obesity is one of the unhealthiest things that can happen to your body. It increases your risk of diabetes, heart attacks, cancer, and can lead to a series of other health complications. But today, the new weight loss drugs are changing people’s lives in a way no diet ever has before. They seem to melt fat away, reduce addiction and even prevent or reverse the negative effects of obesity.

How do these drugs work? What do they do to our metabolism, and could they change public health forever?

      <video:title>Why Is Polio Back?</video:title>
      <video:description>Polio was nearly eradicated. But immunity gaps allow the virus to resurface. The fight isn’t over, and one case can spark an outbreak.

      <video:title>The Virus We Almost Beat</video:title>
      <video:description>Polio once paralyzed hundreds of thousands of children every year. Vaccines nearly wiped it out, but if immunization rates drop, the virus can spread again. This fight isn’t over.

      <video:title>The Lake That Killed a Village</video:title>
      <video:description>A quiet lake released a cloud of carbon dioxide that suffocated an entire village. No warning. No smell. No escape. What happened at Lake Nyos in 1986 and at Lake Monoun in 1984 is a rare disaster, but it could happen again.

      <video:title>Jupiter Made Earth Possible</video:title>
      <video:description>Jupiter once wandered deep into the inner Solar System. It disrupted rocks, shaped Mars, and helped Earth form. Without it, life on Earth might not even exist. Thanks, big guy.

Trees are among the most fascinating life forms on Earth, but what makes them truly fascinating is hiding underground! They are able to break solid rocks with hydraulic roots, all while working together with the underground fungal networks that can stretch for kilometers. Above and below, trees are running biological empires we’re only beginning to understand.

How does something so massive survive with roots growing so shallow? What are trees really made of and how are they able to grow so big?

Getting a tattoo itself might be a dramatic event for your immune system, but things get even crazier when you try to remove them! From intense lasers, to shockwaves and exploding cells, laser removal is one of the most intense things your body can go through. 
What happens when the powerful lasers hit your skin, how do they destroy the ink, and how does your immune system clean up the aftermath of a tattoo removal?

      <video:title>Does Legalizing Drugs Help?</video:title>
      <video:description>Developing an unhealthy relationship with drugs can happen faster than one thinks. The roots of addiction are diverse, and there is no universal remedy. In 2001, Portugal took an innovative route in the fight against drugs: decriminalization.

Our best theory of the universe might be breaking apart! The new data we&apos;re receiving from space telescopes is creating more and more cracks in our current understanding of the universe, and some scientists believe 
we could be standing on the edge of the next great revolution in physics. When did the first galaxies really form? 
How fast does our universe really move and why are the huge cosmic voids not following the cosmic principles?

Trees are among the most extreme and successful forms of life on Earth. They build their bodies from thin air, move water with pressures that would crush a human, and grow using a fascinating system of living cables wrapped in layers of corpses. Under their bark lies a razor-thin strip of living cells, working endlessly to move water hundreds of meters, build indestructible wood, and coordinate millions of functions. 
How do trees work, and what are they even made of? What makes these ancient giants so resilient, and maybe even immortal?

Fat is not just stored energy, it’s a complex organ that controls crucial hormones and communicates with your brain, immune system, and metabolism. It&apos;s one of the most powerful organs, but it can be one of the most dangerous ones, as well. When there’s too much of it, fat can trigger inflammation, disrupt hormonal balance, increase your risk for nearly every major disease, and significantly shorten your life.
What is fat really, and how does it function? When does it become dangerous and can the damage caused by excessive amounts of fat be reversed?

      <video:title>The Most Dangerous Animal</video:title>
      <video:description>Lions and sharks might seem dangerous, but there are much more dangerous animals, like hippos, snakes, dogs and even us, humans! Still, none of them can compare to the truly most dangerous animal on Earth: the mosquitoes!

Stress is a biological superpower that helped your ancestors outrun predators, fight off enemies, and survive extreme situations. In the past, it helped us survive, but today, it’s quietly damaging millions of lives.
What exactly is stress, how did it evolve, and is it even possible to use it in a healthy way?

      <video:description>We don&apos;t know the meaning of life, or how and why exactly it exists, which makes it all that more exciting to think about all the possible answers to those questions! Be kind to others, because you never know if by being kind to others, you&apos;re really being kind to yourself.

Weed is often seen as harmless, and in some cases, even helpful. But for many people, it can slowly become a serious problem, especially as they approach their twenties or thirties. Today, we take a closer look at how long-term daily use can affect your relationships, motivation, mental health, and life in general. Can it really be used safely? How easy is it for weed to turn into an addiction?

      <video:description>Of course, we don&apos;t want to incite anyone, and this is not a guide to causing a nationwide power outage. But if you&apos;re curious about how vulnerable our power grids really are, these could be ways to overload the grid. Hypothetically, of course. And only if there were no smart grids, which there are.

AI-generated content is flooding the internet, from videos and music to news and books. On top of that, generative AI is making false information look more convincing than ever. 
We&apos;re entering a new era of information overload, and figuring out what&apos;s real and what&apos;s not is becoming more and more of a challenge. While AI slop is slowly changing the internet as we know it, one thing is certain: kurzgesagt videos will always remain human-made.

Can we survive the heat death of the universe? One day, the last star will die, galaxies will dissolve, and black holes will evaporate. The universe becomes a cold, empty void where nothing happens. 
Forever. But there might be a loophole that lets life keep going.

Pregnancy is not gentle. Babies begin as invaders, growing a brand-new organ inside another human. For months, they sap energy, hack the immune system, and fight for survival. Out of this struggle emerges the most magical thing there is: new life. 
This is the brutal and beautiful story of how you and all of us came to be.

      <video:description>Can we really power the whole world with renewables? Solar and wind are cheap and clean, but they’re not always available. So how do we store energy and ditch fossil fuels for good?

Some killer asteroids were found only days before flyby. If they had struck Earth, the power of thousands of nuclear bombs would have flattened cities and killed millions. 
What if we spotted a 100-meter asteroid just two weeks before collision? Can humanity be saved?

Most of the universe is not made of stars, galaxies, or beautiful glowing nebulae. Instead, the majority of it is what seems to be vast, silent emptiness. Huge cosmic voids stretching hundreds of millions of light years across, containing almost nothing at all. But these dark regions are not just empty space. They are dynamic structures that grow, merge, and shape the entire architecture of the universe.

What exactly are cosmic voids and how did they form? What makes them so strange, and what role might they play in the future of the universe?

      <video:title>We Made A New Channel!</video:title>
      <video:description>For years, we’ve been dreaming of a second channel. A channel where we could tell different kinds of stories and dive into something else we deeply care about: history. Because the story of the past is also the story of us, of humanity. Welcome to the nightshift. 🌚

Our first video dives into the extraordinary story of Zheng Yi Sao, a young woman who built the largest pirate confederation the world has ever seen. Her floating shadow state of 1,800 ships and 70,000 pirates pushed the Chinese Empire to its limits and reshaped trade in the South China Sea. 

Continue watching on nightshift: https://kgs.link/NGT_PP

We’d love to hear what you think. 🖤

      <video:title>Decadal Antimetabole</video:title>
      <video:description>Antimetabole vs. Chiasmus. What&apos;s the difference?

Up until yesterday, I didn&apos;t know the distinction was marked by separate words. BUT I&apos;m learning everyday 😎

Antimetabole is the reversed repetition of words or phrases. For example: &quot;Pleasure&apos;s a sin, and sometimes sin&apos;s a pleasure&quot; - Lord Byron.

In &quot;chiasmus,&quot; similar concepts or grammatical structures are repeated and reversed, but not necessarily the same words. For example: &quot;It&apos;s HARD to MAKE time, but to WASTE it is EASY&quot;
