I think the little graphene crystals in graphite are tiny so when the pencil breaks, you are separating these crystals rather than breaking any of them.
@@SkillTimO what's the double meaning? No, not no inertia. Inertia is the resistance to change in motion. The more inertia an object has, the harder it is to change its motion. And we're talking about two people colliding into each other so they're not at rest anyway
@@SkillTimO A body at rest absolutely has inertia. "an object in motion wants to stay in motion/ an object at rest, wants to stay at rest" -- but why? The answer to both of these is because it has inertia... So there is a bike and a train both sitting at rest-- You walk up and push the bike and it rolls on it's wheels quite easily, you try to push the train and it doesn't budge--- and that's because it has more inertia: or resistance to change it's motion. With that current motion being: at rest. The more mass an object has, the more inertia it will have/ at rest/ in motion/ and at all times..... I think what you meant is that an object at rest has no "momentum, which is true.

+Licky Time VXV Why? Since it is a good conductor and it would be covering the whole body like a second skin, should not be a problem even if were struck by a lightning bolt, because of the effect of the faraday shield/cage. Am I wrong?
+gilvan romer since electricity finds e fastest way in and out of a object it would go through the graphine and not the human since graphine conducts electricity making it a electric proof armor too
+TheWaki 232 That's a common misconception. If that were the case, tasers wouldn't incapacitate people and would simply cook the skin between the two prongs.
This was a clever presentation. Carbon is such a wonderland. It is scientific Silly Putty. Every way that it is arranged is wonderful and amazing, partly on its own account and partly on its differentiation from other ways it is arranged. How are a pencil and a diamond similar? They are both carbon based. So are we. So are trees. So is the food we eat. We exhale the stuff. We grill steaks on it. It is in some of our lighting. It is abundant and cheap but also precious and rare (when arranged). Sunlight, wind and carbon are where we should be looking for sustainability. Currently we exploit the rarest materials: Gold, copper, water, fossil fuels, titanium, trapped gasses... while the most abundant are under-exploited. The one abundant fuel that we have exploited but in the wrong way is nuclear power. We've used fission instead of fusion. Fusion and graphene deserve much more research. We currently subsidize Big Oil to hunt for more oil in ever more sacred spaces (the ocean, the arctic, our national parks, etc) when we should put the billions into the research that holds the promise of quality of life (and life itself) for our children, not that which is destroying all we hold dear (or should hold dear). Scientists... thank you for your labor of love, working to improve the future. Hacks, who serve corporate interests at the expense of the commons, regardless of the quality of your research you are no better than the demons. And educators like Veritasium, thank you as well.
There was once a legend that sanãtana dharma is not just religion called Hinduism but the way of life😂 And that there are no.of species in the sanãtana dharma that have still not been discovered but is slowly unrevealing And that we should not think as just a state ,or a nation ,or a region but more than that as a human kind,Be what it means to be human being and work together as a whole world to protect the nature of the world and its innocent organisms. Which were created by the celestial alien race and that we should be immortal by transferring our concious into autobots and leave Earth to heal itself and also leave the vast knowledge of vedas to the current apes which might one day become human being.
Why does the graphite in the pencil not have similar qualities? Isn't it essentially the exact same thing as graphene except stacked together? Why is one layer of graphene stronger than a solid piece of graphite? Why do the atoms in graphite not want to be evenly spaced; but they do like being evenly spaced when they are in a single layer?
The layers of graphene in graphite is easily removed from the graphite, meaning it is easy to break the graphite into smaller pieces of graphene. When breaking apart the graphite, you do not destroy the bonds of the material, but just remove the layers of graphene. I can elaborate further if needed.
While layers of graphene inside graphite behave as in the video, the bonds between these layers are very weak and corrupt all the advantages. Thus graphite is excellent in two dimensions, but very weak in the third. Moreover, the orientation of bits ("crystals") of graphite is not all the same, and they are not united into a single crystal like a diamond, therefore what might be the right dimension for one bit is a wrong one for another, so everything becomes more-or-less a mess.
ty_ger The carbon atoms in the graphite aren't in that perfect lattice yet - all the atoms are jumbled together and create weak bonds in every direction rather than strong bonds in single directions. Remember, for the graphite to become graphene they had to make a pile of graphite and slice it down repeatedly until it locked into a single layer and became graphene. Saying graphite and graphene are essentially the same is like saying diamonds and coal are essentially the same. How a thing is built has just as much to do with its function as what a thing is made of.
***** Resorting to name calling is fairly petty, but I'll try to clarify: Pure graphite is composed of Carbon atoms. In graphite, those atoms are arranged in such a way as to create weaker bonds in all directions with atoms at varying distances, because carbon atoms _want_ to group up and share electrons with other carbon atoms, however graphite as a substance has a very high viscosity - the atoms aren't allowed to move around easily to strengthen those bonds. Now if we take a big clump of pure graphite and applied tons of pressure to it from all sides the carbon atoms would start to move closer and closer together and create stronger and stronger bonds, until it hits a certain point where the atoms can't get any closer to each other and they form a 3-dimensional lattice-shape. At that point every carbon atom has a *very strong* bond to every _other_ carbon atom nearby, and we've created Diamond. *_SAME ATOMS_*, different configuration. EDIT: As an analogy, think of a snowball. At first, it's loosely clumped together; almost falling apart. So you take your hands and _squeeze_ it from all sides until it gets harder. It might even get so hard that it turns into ice instead of snow. *_SAME MOLECULES_*, different configuration. In graphene the atoms arrange in a similar configuration to diamond, but along a single plane. Since it's in a single layer, the atoms have extra electrons that aren't bound to other carbon atoms in other directions so it becomes an incredible conductor. EDIT: Extending the analogy, imagine the difference between a meter of snow compared to a layer of ice. If you jump into the snow, it sprays and breaks off into smaller and smaller bits. On the other hand if you run on ice, you'll slip and slide around because of the way that it's structured. *_SAME MOLECULES_*, different configuration. The reason we don't see graphene appear naturally is that very little in the universe happens along a single axis on its own - the atoms innately jumble together unless something acts on them. From a physics perspective we're much more likely to see natural diamond than natural graphene simply because of the way the universe functions.
Hey, great show! Funny style and nice cute presenter! So good to see that these ideas are being spread across the glove, thanks to your team. Love your work and especially that cutie in the suit with a beard! Yum!
That moment when someone drags you into a room and won't let you go until you have created the thinnest yet the most resistent material on earth with only a pencil,a sheet of paper and a scotch tape.#relatable
This can be used on airplanes to increase the strength and durability of the skin. Also its conductability could act as extra protection against lightning strikes. Another pro is that because it is clear, so It can be added on the outside of the windows of the plane, without affecting the view. Who thinks this is a good idea!
Lightning won't go through two thick layers of plexiglass, through the air gap, and through you... None of those are very conductive. It'll pass through the aluminium body of the plane like a faraday cage. This is not a problem in need of fixing!
Hi, from the future here. This video ended with an ad for "Monolayer Graphene Film" only 300 Trump Imperial Credits for 60mm x 40mm. What a capital deal!
So i could make graphene using tape, and while this graphene stuck to the tape is super strong, i wouldnt be able to say, stab a pencil through the tape and the graphene as well?
Felix Coreston and that means we could make flying saucers outta this stuff. Spider silk is stronger than steel, btw, which will be perfect for spacesuits ....(-:
i did this way before 2010, i was just playing with lead sticking it on tape. i noticed perfect hexagons. i thought it was dope but didnt think anything of it. this was like 2001.
He got thrown in a chair and is forced to make something seemingly impossible (but obviously isn't) and when he's finished they high-five and look like they're best friends. Am I the only one why finds this confusing?
Mateusz J What is its name? What is the method? How much does it produce and in what amount of time? Also, could you please define what you mean by affordable.
***** I'm not saying it's not true. I just want to know what it is. I think it would be amazing if it were true, but I personally need proof. I'm sorry.
A single layer of atoms can support the weight of an elephant concentrated into the size of a pencil? I cannot believe that. It might make a good video. It's easy to test in a materials lab. Provided you can find a reasonably large slice of graphene.
Graphene oxide is not a sheet of graphene. To answer your question, almost transparent and nearly impossible to feel- easy to tear, even. It's the relative strength that counts.
antiHUMANDesigns That's correct. The actual color of graphene is in fact a very dark, blackish grey but due to the molecular structure what we see is near-complete transparency.
"The earliest TEM images of few-layer graphite were published by G. Ruess and F. Vogt in 1948"'. Although, the most advanced- so far and by far- method of obtaining the graphene on a quazi-mass scale was discovered... it's hard to say that was invented... in Poland a decade ago or so ! The Blue Laser as well... First professional computer in Europe made on a mass scale also in Poland- The ODRA- 1972 A Pole Copernicus busted Ptolomenian Solar Orbiting the Earth theory in 1543. Maria Curie was a Polish girl. Polish mathematicians; Rejewski, Zygalski and Rozycki broke the Enigma code in 1932... Serendipity and Eureka rolled into one; yet... who cares ?! Folks in China, Russia, India... everywhere out there have already taken advantage of it, made their own usage of the Polish inventions and discoveries.. Who cares ?!!!! Well... I do! Cheers guys !
Tři III van Wabawooo Well...a good sport of you... Anyway, some Poles are working on that... By the way... Mr. Twardowski was according to the urban legend first into the moon back in XVII c. Let alone Stanislaw Lem was the first sci-fi writer who sent Polish literature into the orbit of our Milky Way, look it up in Encyclopaedia Britannica- (the title of the book is "Solaris") Cheers to you !
Tři III van Wabawooo Oh... I see... so am I.... another meme !!!!! TTTT I hardly ever watch videos on YT... This time was not an exception. No, just kidding... I love watching spooky movies... Cheers to you anyway !

There is a difference between strength, hardness, and toughness. For example, a diamond is one of the hardest minerals, if not the hardest, with a score of 10 on the Mohs scale - it can cut anything but can only be cut by things as hard as itself.; however, it's not very tough - you can shatter it with a hammer. Tensile strength is how well it can resist a force trying to pierce it or pull it apart. Also, graphite is not the same thing as graphene - graphene is a single layer, where graphite is many layers stacked on top of each other. The pencil is breaking between the layers.
Graphene is a single layer of graphite. Graphite is a material that peels of layers because the bonds are very weak but once you get to a single layer there is no more to peel off. This is the difference between them.
***** Oh please. You know for someone who has a master's degree (which you don't) you act like your're some kind of bad ass. Are you kidding? I'm not old enough but I can guarantee that I can get a master's in what you get. It has nothing to do with not being intellectual enough. Also for a college graduate you're grammar is absolute garbage. Next time if you're going to tell someone their not intellectual enough, at least make sure you can properly type sentences. Unbelievable. Or you're some kid who is seeking attention.
***** So what are you exactly, a late 20 yr old with the temper of someone who is 4? trying to impress some faceless blobs of text disagreeing with you on the internet? I realize that is exactly what I am doing but I don't pretend to be better than my equal man. If all of your years of schooling have still brought you no wisdom, I would please ask you to get off of the internet and off of my level, sir.
+Veritasium Well... the one with the elephant is misleading (if not just plain wrong). A single layer of graphene can hold only 4 kg without breaking. But multiple layers stacked on top of each other (with a total thickness comparable to that of paper) COULD hold that elephant on a pencil. Just saying...
