Boredom makes you more creative, altruistic, introspective, and helps with autobiographical planning. This video was sponsored by LastPass: http://bit.ly/2wAsdUu I feel like this video might come across as condescending but the person I'm really talking to is myself. Despite the fact that I know how useful it can be to be bored, I still find myself trying to fill every last moment with stimulus. Boredom is unpleasant - the open, unstructured thinking that can take place can also feel pointless. But now I'm made this video to remind myself how important boredom is so hopefully I'll make more time to be bored.

The nutrient content of food is declining. Is it because of soil depletion, selective breeding, or... something else? Watch my new documentary, VITAMANIA: http://ve42.co/vita I came across this story as I was making the film Vitamania. When you ask sellers of vitamins why you should take vitamin supplements even if you eat a healthy diet, they will say because our food doesn't contain all the nutrients it once did. This is supposedly due to soil depletion, cold storage, food ripening off the vine, and global transport of out-of-season foods. And to an extent this is true. Foods contain the greatest amount of nutrients if they are eaten soon after they are harvested. An unexpected source of nutrient decline is the increasing amount of carbon dioxide in the atmosphere. It causes plants to grow faster and bulk up on carbs but at the expense of other nutrients, so in percentage terms the amount of nutrients are actually declining. For now this decline is modest so supplementing with vitamin pills is probably unnecessary for most people with a healthy diet but it may be a concern in future.

The truth, with photons. I hope I've articulated everything clearly in this video. If not, I'll clarify in comments. Thanks to everyone who appears in this video and thanks to everyone who watches this video! Veritasium is of course a combination of the latin 'veritas' meaning truth, and the common element ending 'ium'. I guess this is my version of the 'draw my life' craze that rolled through YouTube many years ago. Except I wanted to tell my story with the actual moments, the photons, the stored magnetic states. There's something about that which is so important to me (because I think the alternative involves fooling yourself) which is why I'm so fascinated by film and video. One of my inspirations for the name Veritasium came from the end of the poem Ode on a Grecian Urn by John Keats, in which he writes: "Beauty is truth, truth beauty,—that is all Ye know on earth, and all ye need to know."

I always thought of the characters in our story as the scientists and maybe the uranium nucleus itself. It was only through making the documentary that I realized the real hero of the story is the neutron. Without a neutral nuclear particle, it would be virtually impossible to release the energy from the nucleus. But with it, and the idea of a chain reaction, nuclear energy went from science fiction to reality. That is something I had not grasped as clearly before and it motivated me to make this video.

Will artificial intelligence weapons cause World War III? https://www.youtube.com/watch?v=qiJTq11kqdw This animated clip is from my friends at http://ve42.co/pindex2 New series! http://vrv.co/paradigms I'm not sure how alarmed to be about artificial intelligence. Personally I think it's really hard to predict when we'll create a machine that essentially has consciousness. That's because we don't know what consciousness is, how it works, what's required to create it etc. So It might be technologically around the corner or a hundred years away. What I do think is more predictable is the development of autonomous weapons that use AI to be the most effective killing machines of all time. That is scary. As outline by people like Musk and Hawking, this threat is clear and present so we should address it. I would like to see us agree as a species not to develop these sorts of weapons because if any one state does develop them, they would be very hard to stop.

Mosquitoes are attracted to me and it's likely due to my genes. This video is sponsored by 23andMe https://23andme.com/veritasium Huge thanks to Prof. Immo Hansen and team: http://ve42.co/hansen References: Genome Wide Association Study for self-reported mosquito attractiveness: http://ve42.co/MossieGWAS The twin study showing correlated attractiveness is stronger for identical twins: http://ve42.co/MossieTwins Some things we know make mosquitoes more attracted to you: Exercising, higher metabolism, higher body temperature, more body odor, being pregnant, type O blood, infrequent bathing, lactic acid, ammonia, acetone. There are a number of folk remedies people believe protect them from mosquito bites like drinking alcohol, eating garlic, or taking vitamin B. These do not appear to provide any benefit in lab studies and in fact drinking alcohol is associated with increased mosquito activity because it causes blood vessels near the surface of the skin to dilate. And apparently some of your attractiveness to mosquitos is simply genetic. This may be mediated through your immune system, which is what a lot of the genes identified were associated with.

I got to drive the world's first car (replica), patented by Benz in 1886 Check out the series on new safety features: http://ve42.co/MB This video is sponsored by Mercedes-Benz, who invited me to come to Stuttgart to see their latest cars, crash test facilities and experience the innovations they are working on. Physics is something that is directly applicable to car safety. Cars go fast, but they also sometimes collide with obstacles, which brings them to a sudden stop, subjecting the car and occupants to very high accelerations, which can cause injury or death. So the major idea to improve car safety is to reduce these accelerations and there are a number of ways to do this: Passive safety: Seat belts: keep passengers in the vehicle, preventing them from continuing with constant velocity, flying through the windshield and suffering a worse deceleration when they make contact with the road. Crumple zones: increase the distance over which deceleration occurs, thereby reducing peak magnitude of deceleration. Air bags: increase the distance over which the head decelerates, again reducing peak magnitude of deceleration of the head. Active Safety: Anti-lock braking system: rather than 'locking' the wheels as can happen if you slam on the brakes with a traditional braking system leading to the tires skidding across the road, ABS attempts to control the amount of braking so that the tires always roll with static friction in contact with the road. This increases the backward frictional force that can be applied to the tires, again increasing the distance over which deceleration occurs, and it gives the driver an opportunity to steer to avoid the collision (hence why it's referred to as an active safety system). Special thanks to Mercedes for having me visit facilities in Stuttgart. I had a lot of fun making these videos so please do check out the series on Mercedes Benz's channel: http://ve42.co/MB Filmed by Simon Schneider Edited by Hoplite Creative and Trevor Carlee

These are the molecular machines inside your body that make cell division possible. Animation by Drew Berry at the Walter and Eliza Hall Institute of Medical Research. http://wehi.tv Special thanks to Patreon supporters: Joshua Abenir, Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen Support Veritasium on Patreon: http://ve42.co/patreon Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old - this is normal, in fact it’s called programmed cell death. To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells. And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start - the double helix molecule that we always talk about. This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C. Now the strands run in opposite directions, which is important when you go to copy DNA. Copying DNA is one of the first steps in cell division. Here the two strands of DNA are being unwound and separated by the tiny blue molecular machine called helicase. It literally spins as fast as a jet engine! The strand of DNA on the right has its complimentary strand assembled continuously but the other strand is more complicated because it runs in the opposite direction. So it must be looped out with its compliment strand assembled in reverse, section by section. At the end of this process you have two identical DNA molecules, each one a few centimeters long but just a couple nanometers wide. To prevent the DNA from becoming a tangled mess, it is wrapped around proteins called a histones, forming a nucleosome. These nucleosomes are bundled together into a fiber known as chromatin, which is further looped and coiled to form a chromosome, one of the largest molecular structures in your body. You can actually see chromosomes under a microscope in dividing cells - only then do they take on their characteristic shape. The process of dividing the cell takes around an hour in mammals. This footage is from a time lapse. You can see how the chromosomes line up on the equator of the cell. When everything is right they are pulled apart into the two new daughter cells, each one containing an identical copy of DNA. As simple as it looks, this process is incredibly complicated and requires even more fascinating molecular machines to accomplish it. Let’s look at a single chromosome. One chromosome consists of two sausage-shaped chromatids - containing the identical copies of DNA made earlier. Each chromatid is attached to microtubule fibers, which guide and help align them in the correct position. The microtubules are connected to the chromatid at the kinetochore, here colored red. The kinetochore consists of hundreds of proteins working together to achieve multiple objectives - it’s one of the most sophisticated molecular mechanisms inside your body. The kinetochore is central to the successful separation of the chromatids. It creates a dynamic connection between the chromosome and the microtubules. For a reason no one’s yet been able to figure out, the microtubules are constantly being built at one end and deconstructed at the other. While the chromosome is still getting ready, the kinetochore sends out a chemical stop signal to the rest of the cell, shown here by the red molecules, basically saying this chromosome is not yet ready to divide The kinetochore also mechanically senses tension. When the tension is just right and the position and attachment are correct all the proteins get ready, shown here by turning green. At this point the stop signal broadcasting system is not switched off. Instead it is literally carried away from the kinetochore down the microtubules by a dynein motor. This is really what it looks like. It has long ‘legs’ so it can avoid obstacles and step over the kinesins, molecular motors walking the other direction. Studio filming by Raquel Nuno

The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates: - the first gravitational waves detected from inspiraling neutron stars - the first joint observation by gravitational wave and electromagnetic wave astronomy - identification of a gamma ray burst in conjunction with merging neutron stars - how gravitational waves and gamma rays can be used together to locate their source All evidence so far indicates that the data support General Relativity.

On a stream of water you can levitate light balls of all sizes and even disks and cylinders. The mechanism is not the Bernoulli effect... Want to make this at home? https://youtu.be/BppcHF2EdAY My friend Blake from InnoVinci emailed me with a cool idea for a video and footage of levitating balls in water streams. Initially it was tough to explain the physics of what was going on. The standard Bernoulli effect relies on the object being completely immersed in the upward-flowing fluid. But in this case the water seems to form a single stream around the object and it's deflected away and down from the stream. By Newton's third law, the force on the water by the ball is equal and opposite to the force of the water back on the ball, pushing it up into the stream. There is a stable equilibrium position because if the ball moves into the stream, it "cuts off" the water going over the ball so it drifts out. If it drifts out too far, then lots of water passes over the ball, pushing it back into the stream.

When you focus the sun's rays using a magnifying glass (or in this case sphere of water) you can increase the intensity roughly ten thousand fold. This increases the temperature of wood to its autoignition point starting the reaction with oxygen in the atmosphere.

Surely there's an accurate way to measure forces without creating such a huge known force?! Nope. This appears to be the best way, with a stack of 20 x 50,000 lb masses creating a maximum force of 4.45 MN or 1,000,000 pounds of force. I also wouldn't have thought about all the corrections that need applying - for example buoyancy subtracts about 125 pounds from the weight of the stack. Plus the local gravitational field strength must be taken into account. And, the gravitational field varies below grade. All of this must be taken into account in order to limit uncertainty to just five parts per million (.0005%) Music from The Epidemic Sound http://epidemicsound.com "Serene Story 2"

In 2020, NASA will send a new rover to the Martian surface with one of its objectives to search for evidence of ancient life on the planet. I made this clip as a correspondent for Bill Nye Saves the World on Netflix. Touring the Jet Propulsion Lab (JPL) in Pasadena was an awesome experience. I didn't think we were going to get into the control room but we got lucky. Some of the greatest moments in the history of space exploration have taken place there. They have a giant vacuum chamber where they can take the rover down to the atmospheric pressure on Mars (roughly .01x Earth's atmosphere) and test all of the devices to make sure there are no electrical discharges due to the reduced pressure. I also enjoyed seeing how the rocks will be cored and stored in tubes and deposited on the Martian surface awaiting pickup by the following mission. Images courtesy of NASA.
