For more on spin, check out: This video was supported by TechNYou: A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits. Thank you to Andrea Morello and UNSW. For more info, check out:

This is what the world would look like if you could see invisible air currents, temperature gradients, and differences in pressure or composition of the air. Support Veritasium on Patreon: Special thanks to Patreon Supporters: Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen I first saw a Schlieren imaging setup around ten years ago in Melbourne. I was immediately fascinated by the way I could see the warm air coming off my hand. I hadn't expected the currents to be moving that fast or to be so visible. This was a tricky setup to get right because alignment is very important and here I'm just working with what I had lying around the house mostly (plus the mirror). For the best Schlieren photography, making sure the mirror is stable is essential. I want to improve my setup so the mirror doesn't wobble back and forth too much creating the pulsing light and dark sections of this video. The relationship between index of refraction of air and temperature, pressure, humidity and wavelength is complicated.

And although we’ve spent much of our history coming up with ways to detect these lies by tracking physiological changes in their tellers, these methods have proved unreliable.

A head-vaporizing laser with a perfect wavelength detecting sub-proton space-time ripples. Huge thanks to Prof Rana Adhikari and LIGO: Here's how he felt when he learned about the first ever detection: Thanks to Patreon supporters: Nathan Hansen, Donal Botkin, Tony Fadell, Saeed Alghamdi, Zach Mueller, Ron Neal Support Veritasium on Patreon: A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible. When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

We’re given very little guidance on how to choose our partners and tend to leave it to that mysterious force we know as ‘instinct’. However, it truly pays to be a little more rational in this area and work out how our instincts operate and why they push us towards some people and away from others. If you like our films, take a look at our shop (we ship worldwide): Join our mailing list: Or visit us in person at our London HQ FURTHER READING “How do we choose the people we fall in love with? The Romantic answer is that our instincts naturally guide us to individuals who are kind and good for us. Love is a sort of ecstasy that descends when we feel ourselves in the presence of a benign and nourishing soul, who will answer our emotional needs, understand our sadness and strengthen us for the hard tasks of our lives. In order to locate our lover, we must let our instincts carry us along, taking care never to impede them through pedantic psychological analysis and introspection or else considerations of status, wealth or lineage. Our feelings will tell us clearly enough when we have reached our destiny. To ask someone with any degree of rigour why exactly they have chosen a particular partner is – in the Romantic world-view – simply an unnecessary and offensive misunderstanding of love: true love is an instinct that accurately and naturally settles on those with a capacity to make us happy.…” You can read more on this and other subjects on our blog, here: MORE SCHOOL OF LIFE Our website has classes, articles and products to help you think and grow: Watch more films on RELATIONSHIPS in our playlist: Do you speak a different language to English?

The Higgs Boson is awesome but it's NOT responsible for most of your mass! Thanks to audible.com for supporting this episode: The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons and neutrons, made of quarks, do not. In fact the quark masses are so small that they only make up about 1% of the mass of the proton (and a similar fraction of the neutron). The rest of the mass comes from the energy in the gluon field. Gluons are massless, but there is so much energy in the field that by E=mc^2 there is a significant amount of mass there. This is where most of your mass comes from and the mass of virtually everything around you. Thanks to Professor Derek Leinweber for his great images, animations and explanations.

When faced with a big challenge where potential failure seems to lurk at every corner, you’ve probably heard the advice, “Be more confident!” But where does confidence come from, and how can you get more of it? Here are three easy tips to boost your confidence. Lesson by TED-Ed, animation by Kozmonot Animation Studio.


How did everything get started? Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don't have all the answers yet so let's talk about what we know. Also, we try to make this one not depressing. Tell us if we succeeded. BY THE WAY. We have a website now. We'll try to blog from time to time, show you guys how we make the videos and give more insight to our process. Also we sell stuff.

The current crisis in Iraq explained in under 5 minutes. There is war in Iraq? Again? And the US and Iran are talking about working together? And who is this ISIS Terrorist group that is all over the news? And Religion? Oh dear. When exactly has the world gone mad again? It is not possible to explain a complicated topic like this without simplification. We are very aware that this video is not painting a full picture of the situation. But we hope that it may lay the foundation on which you can try to do your own research and understand how horribly Fu**ed up the whole situation is. We did have to produce the video super fast -- thanks a lot to our friends Martin Wackerbauer and Magnus Schlüter for helping us out -- we would not have been able to make this video in time without you guys! Kurzgesagt loves all people as long as they don't hurt others and don't hinder mankind on its quest to the stars. So it was very sad to read so much terrible stuff about the situation in Iraq. Hopefully it will get better. You can get the music of the video here: Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe. We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful. Visit us on our Website, Twitter, Facebook, Patreon or Behance to say hi!

Thanks to the British Museum! Go help choose their first YouTube series: The Rosetta Stone is one of the most famous archaeological finds in history: and it was the key to cracking Egyptian hieroglyphics. And while it took scholars years to work it out, there was one clue in there that helped unlock everything that followed. After hours in the British Museum, I went to explain.

View full lesson: There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy. Lesson by Jeff Phillips, animation by Provincia Studio.


Banks are a riddle wrapped up in an enigma. We all kind of know that they do stuff with money we don’t understand, while the last crisis left a feeling of deep mistrust and confusion. We try to shed a bit of light onto the banking system. Why were banks invented, why did they cause the last crisis and are there alternatives? The music from the video is available here!

Today's guest video is from Grady at Practical Engineering! Go subscribe: The Hyatt Regency Hotel collapse was a disaster that changed engineering: it's taught in colleges and universities as a way to make it clear: you check and double-check everything. Something that seems like a subtle change can cause a catastrophic failure if it's not thoroughly checked first!


View full lesson: The biggest kidney stone on record weighed more than a kilogram and was 17 centimeters in diameter. The patient didn’t actually swallow a stone the size of a coconut; kidney stones form inside the body. So how do they grow in the first place? And why are they so painful to get out? Arash Shadman shares the science behind kidney stones. Lesson by Arash Shadman, animation by TED-Ed.

View full lesson: You and your team have crash-landed on an ancient planet. Can you appease the three alien overlords who rule it and get your team safely home? Created by logician Raymond Smullyan, and popularized by his colleague George Boolos, this riddle has been called the hardest logic puzzle ever. Alex Gendler shows how to solve it.

If you want to try this experiment, instructions are here: link.springer.com/article/10.1007/s12650-016-0383-5 The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, I think I can safely say that no one understands quantum mechanics. This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time. Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion. Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness. Edited by Robert Dahlem Sound design by A Shell in the Pit

The mysterious YouTube algorithm. It's confused people for years, and will continue to do so. So why isn't YouTube more transparent? It used to be that they wouldn't tell anyone how it works - but now, it's that they can't. Let's talk about deep learning algorithms, neural networks, and search engine optimisation. CREDITS: Thanks to animator Matt Ley for the wonderful cartoon of me: I put this together in three days, plus a day of checking and proofing, in Adobe After Effects. It took about eight hours to render, but that's because every frame has keying, lighting, camera, and motion blur effects, and because the original footage of me was in 4.6k lossless. Yes, the sound of the black box working is the sound of a microwave (it's the one in my kitchen). Also, those aren't faked desktop screenshots, I had to install a copy of Windows ME to make this. SOURCES: Deep Neural Networks for YouTube Recommendations , [PDF] — some people are saying this link 404s, but it works for me? Search for the title and you'll find it. There's a good layperson summary of the paper here: The Defamation Act is published under the Open Government License 3.0: and is available at The music in the cartoon section is called 'Ukulele Beach', and it's in the YouTube audio library. REFERENCES: There are a lot of references and in-jokes in here, and hopefully people will spot most of them in the comments. But if anyone wants confirmation: yes, there are references to Billy Joel, Aqua, a He-Man remix, and Elton John. The last one's pretty obscure, well done to you at home if you got that.
