@@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

[@calholli]

@@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.....

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.

[@locke_ytb]

[@user-dj1hy6zc6q]

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?

[@DirtyPoul]

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.

[@Kurtlane]

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.

[@chrisv4496]

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.

[@ShadowVipers]

+Ham_ Uhh Yes

[@chrisv4496]

***** 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.

(sorry,just had to write a few notes for myself) Thinnest material known to man, strong, best thermal conductor, good conductor of electricity. Nano tech (devices or material less than 10 nanometers in size) Nanometer = a billionth 1/1,000,000,000 of a meter. About the size of ten atoms. Pencil has graphite which has carbon in a hexagonal bleh When you write, sheets of those graphite stick to the paper, usually many layers at a time, sometimes there's a single layer of carbon atoms and that's graphene It conducts electrons faster than any other substance at room temperature. No atoms out of place. Strong but flexible bonds. Scientists making faster touch screens, more efficient solar panels, tougher material, and better computers with nano tech (probably other stuff too)

[@CasaErwin]

If graphene is so strong, why does pencil lead break so easily?

[@freshoutofcrabs]

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.

[@ryangoss8134]

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.

This is simply an observation (not a dis or otherwise) your accent is much more pronounced(pardon the pun) here in one of your earlier videos than in any of the video from the last 4 or so years since I have been watching your KZbin channel. Please continue to make high quality science videos and please continue to not let those quintessential human emotions of pride and down right pig headedness get in the way of doing what you do. Science isn't about being right that one time but about amending your model to fit reality and I hope you continue to do so with the quality and charisma that you do in 2017.

I think it is odd that he never mentioned how balls off the wall expensive the stuff is to produce.

[@mateuszjanowski2521]

there is a company that has a method to produce graphene that is affordable.

[@NoobFish23]

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.

[@NoobFish23]

***** 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.

[@mateuszjanowski2521]

Andrew Halverson The company is called 'Azoty Tarnow'. Unfortunately they didn't give any details of how it's made.

[@carolynmmitchell2240]

Andrew Halverson look up how to make it now, you can make yourself dirt cheap

[@Rampster27]

time to brake out the scotch tape.

[@toni8675]

+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...

[@breakthewastedspace]

Correct me but graphene have layers it would become WEAKER.

[@breakthewastedspace]

+Trainer_Poke note : I'm not sure

[@toni8675]

No. The individual layers would remain strong. But the forces holding together two or more layers are weak.

[@breakthewastedspace]

toni8675 ok thx

[@Timpling]

You're wrong you fucknut.

[@divdac]

I sooooo thoroughly enjoyed this video o my days

[@hannahkitty90]

This is a simultaneously adorable and informative video!

[@mowu8459]

i'd watch this movie

[@YousafHDar]

i did my whole Physics coursework on Graphene. lol. And i had to do a presentation to the whole class about it and got an A. AS-Level. jus sayin.

[@romanr9883]

so if one layer of atoms taken from a penciltip is stronger than diamonds and a pencilmine itself persists out of millions of those layers, how come that the pencilmine itself isnt stronger as diamonds?

[@alphamineron6923]

This needs to be answered!!

[@alphamineron6923]

Although I think that when you have a 1 Atom thick Graphene then its stronger rather than billions of layers of graphene making graphite. I guess it has something to do with the fact that you can really put any actual pressure on it since its just one atom thick but Graphite is billions of atoms thick so you can actually put pressure on it and break it!

[@romanr9883]

+Alpha Mineron i guess bc the strong structure only exists in 1 2D layer of graphene, and 2 layers or more on top of each other dont have nearly as strong of a connection than the single layer has. its like stacking 100 carpets on each other. 1 carpet itself is maybe strong and cant be ripped apart, but you can easily remove 1 carpet from another, and a stack of 100 carpets wouldnt be that stable either. sadly that would mean that u could never have a block of graphene or something, that would than be harder than diamond

[@alphamineron6923]

+Roman Randhahn Well We can make a a 1 atom thick layer of graphene. The Block thing can't happen :( I would love having a Graphene Super Car so I can actually play GTA in real life :/ guess Its never gonna happen BTW, your right. The bond between individual layers Is weak that's why Graphene is stronger.

[@hitanshshah7162]

+Roman Randhahn the bond between two graphite atoms is super strong but the bond between layers of graphite is weak and hence graphene is strong but graphite is weak

[@michaelweedmark2774]

Am I the only person who want a knife made of this stuff?

[@michaelweedmark2774]

***** Im thinking of a steel body with just the cutting edge made of this.

[@RunItsTheCat]

michael weedmark It would be one of the strongest blades known to mankind.

[@michaelweedmark2774]

RunItsTheCat I know! >:{D

[@jsherer9616]

Could it cut anything? I mean, a knife is a wedge, and graphene is more like a plane.

[@michaelweedmark2774]

John Sherer You could always orientate 2 planes to form an edge.

[@ericjane747]

This is the funniest science video ever created!!!

[@atomicedm6180]

1 atom thick condoms?

[@BRAAAHABLAHGH]

Graphene isn't /that/ flexible.

[@robbytrebor8939]

+Alan Johnson and its surely indestructible! can we use this all over again? 1000 times hahahaha

@ 3:31 when two bodies of different mass collide with each other, the smaller mass body approaching a larger mass will bounce back in a collision. :-)

[@zoltangelencser7092]

Excellent video! Thank you Derek.

[@IBsheepy]

In graphene and graphite layers, there are 3 strong sigma bonds in the plane of the layer and 1 weak metallic-style delocalised "glue" bond. in graphene, all the layers are in the same plane, meaning that all of the strong bonds stick strongly in one direction; in graphite the layers are jumbled up in different planes so that the graphite is uniformly strong but not exceptionally strong in any given direction due to the easy to break bonds between layers.

[@johnrafaelferrer9824]

One of the best Veritasium videos.

[@navyatayi6956]

this is one of my favourite veritasium videos!

[@IIIBioniclerIII]

because every layer itself is super strong, but a lot of layers aren't. it's like a bunch of paper. you can easily slide the one at the top to the side, right? (your force is parallel to the bunch of paper) but it's harder to tear one sheet of paper apart. (the force is parallel to the surface of the paper) : ] hope it helped a bit

I feel like this is something I would see in the morning during a commercial break on the TV.

[@Goku_in_Real_Life]

Triboluminescence is an optical phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed. The phenomenon is not fully understood, but appears to be caused by the separation and reunification of electrical charges. Triboluminescence can be observed when breaking sugar crystals (especially Wint-O-Green Life Savers) and peeling adhesive tapes.

[@austinrhodes5864]

I have to confess that on a science test i was about to get a 100% and the last question was what is the hardest element that we studied in class (diamond) and because i saw this video i put down graphene to be smart and I didnt get a 100% i blame you veritasium
