3000 ball bearings show crystal defects with Matt Parker

May 02, 2020
I had a lot of fun on Matt's channel making a video on how to pack clothes, but it's very related to

crystal

formation,

crystal

defects

and things like that, and I actually built something that demonstrates how crystals form and how crystals form. flaws, so I'm going to make a video on my channel about that and Matt, you're staying. Yes, there may be some trouble. I love the mouse, so every once in a while Matt might say some numbers or something like that sixth, that's good. one one is a different number okay so yeah now they used to be a toy you could get in the sixties and seventies called Atomics and you can't get it anymore which is a shame because it meant I had to spend hundreds of pounds making my own recreation actually created the - oh my gosh, and here it is, it's thousands of

bearings

.

I can see where all the money went, but most of it in the recording on youtube.com I'm afraid the most involved, well I just thought if someone converts this. I turned it into a gift and put it on Facebook, but at least I have some funding and I think they can ruin it, yeah, nice, don't do that, don't do that. I mean, I probably exaggerated with the fact that you get into each of the

ball

s that was heads, pretty good, um anyway, it looks like you, if you let the

ball

s fall like that, they organize themselves in place and lattice, which is related to the video we did with this gentleman about closed packaging, definitely check that out.

More Interesting Facts About,

3000 ball bearings show crystal defects with matt parker...

By the way, and if you haven't subscribed to my channel, do that too because to be honest, it's almost all the time, although my subscribers are probably a strict subset of those subscribers, but anyway, if for some reason you have the case before my eyes. let's go there, come on, I know a little about that, I just don't do a little, yes, I do sometimes, when I talk about the city mainly, so anyway, in the fall we naturally fall into a regular network, the brilliant thing about this is that you can. Look, it's not perfect, is it? and the defect in this arrangement of spheres closely matches the

defects

you get in real crystals in the real world.

Also, this might be a good analogy for how, say, our Domain atoms are arranged in a metal, so we still manage to eliminate these holes. So that is an example of a defect that you could have that is called a point defect because it is happening at a point in the network, a point where an essence should be and that is called vacancy. This should be one that ticks off and you see that it's nice and stable. Well, look at something really interesting in a real crystal, you know, you could have neighboring atoms, just jump into that gap, yeah, instead of moving the problem, yeah, I would, yeah, so brilliantly that you can have a hole that move across the ladder. typically atomic yeah so let's take a look at another defect because I feel like there are lines yeah okay here's a lattice region and here's another lattice region and these are all hexagonal packings everything is hexagonal very efficient , yeah, like a honeycomb, except this The regions of this region are at slightly different angles, they don't line up, so you know you have everything like this and this was good and when they meet they don't fit together, yeah, and that also happens in the real world, it's called a grain boundary, so if you have a crystal growing here and the crystal growing here, they collide, that's how they could do it, but here's another one that's pretty interesting, let's just readjust that, okay, so here, let's see this one here, oh yeah, there. there's a line there, it's a straight line, it's a bigger gap than the rest, so this crystal and this crystal are oriented the same but for some reason they don't quite match up, they don't line up, yeah, this is not really a perfect analogy. for anything in the real world, but it's close enough to a certain type of defect that is actually very interesting, it's interesting enough to buy a lot of pit bulls.

In fact, I'm going to try to build a crystal because they're just getting started. I'm really looking into closed packaging, just yeah, I couldn't believe what I saw, I know and now I'm interested. I mean, the rest of it was great for me, but the closed packaging that was a bit of a click bait was not. when I just said you won't believe where these things are centered ah because this guy got stuck how are they cute? you won't believe what happens next okay the third layer of balls will remind you of your bike yeah okay we.
I need to go into 3D for this to work because this is a stacking defect or a stacking fault so now I'm really excited if you open the box there's your box of green balls so now I have our layer. hacked very efficiently, yeah, good job, hexagonal packing on the first layer of green balls, so to distinguish the next layer we are going to use Red Bull, okay, so what we are doing is like the next layer, yeah, as if they were atoms of some kind. of glass lattice, so yes these are located in the little gaps possibly created by three green balls that touch whoever comes from, yes I can see why children like to play with them, yes I don't think they do this in bubbles, that's what I do well. okay so we have two layers yeah so far so good let's add this advantage right there we are all different teams oh okay yeah my big yellows like to necessarily attack all the blues so I see honestly what are the challenges that still exist. like it's a simple little berry, you see, okay, he's about to say if you put that there I can't put wine on my lattice, but then I realized there's a point, yeah, yeah, you're going to back off. like he was an idiot.
There is an interesting one there, so it turns out that when you put the balls down there are actually two options or two options, yes, and they are incompatible with each other, so you started putting yours there. I thought I went here and they get together and they can't. we finished the network so now we have this space through which two pieces of the crystal growing would hit here and we would get what you called this thing, so this is a stacking fault, what that means is where I place my balls in relation to the two layers above are different to where my lines line up with the green ones, yes, so mine is the same as the bottom layer, yes, if you look down, yes, and I look through the holes between the red balls, I see a green ball immediately. either you don't see it or you still don't see a gap and no, you went for the gap I went for the gaps where did you go for a deeply nice alignment with the layer below?
So yeah, so your layer is exactly the line with the green layer, mine is not. I want it to be efficient, each layer has to be different from the one directly below it, yes, then you have a choice, it can be the same or different from the one below, yes, and that's it. the next layer has to be one of those three again okay there's our fourth option yeah so the way we set up the blue balls here the first second and third layer are all different so we can label them as B and C correctly and continue.
Thank you very much for confirming the variation, you know, I once used on my channel why am I here, so I took a lattice that says ABC ABC ABC ABC is a face-centered cubic lattice, while what you have done with renewable material or expected is a capable UAV in Italy, which is a closed hexagonal note, we are all going to correct the hexagonal closed package, the erect lattice, yes, the country, your diagram, yes, I like it, okay, so you have labeled correctly that you have three options, you have a Z, this is I'm not writing neatly and I see two different layers and I think of it as a triangle of options, okay, so if I change, when you would do what I was doing here, it was just bouncing from A to B, from A to B, so I'm going back and forth on an edge, if you choose something that goes back and forth on a certain edge, you're going to get the closed hex packing, yeah, and then if you did it here , what you are doing is going around the triangle. make regular turns around the triangle that gives you your cubic and facial packing and then the cubic mask.
Yeah, the same thing is centered on the face, so what you can do obviously is any other combination of those, yeah, so if we did another one right. it's going to be a little bit more consistent and we did ABC, there's no reason why we can't go back to B and then to C and then to a and then to B and then, then you can travel, yeah, yeah, you can change wherever you want. you want the right thing, yeah, and then if you get the two cycles, you get the two regular ones, yeah, for the rest, you just get the stuff that happens on all fours, and since there's no, ultimately, there's no limit, yeah , it means that there are infinite possible ways to create your crystal lattice by stacking spheres knowing and no

matt

er how you go through this diagram, it is the most efficient way, but in practice it is, it does not change the percentage of volume you are filling with a sphere yes no , interesting, there is another type of crystal failure actually that's still, so it's called antiphase limit, so I get a crystal that is face centered cubic, we'll go ABC ABC ABC ABC everything, but maybe at some point it will go ABC ABC ABC ABC CBS CB a CBA it will change so you will go ABC ABC ABC OB a television area yes both crystals are facing two cubics but they just collide with each other and you take the mirror image basically I like it do if.
So, and what's really cool is that the face centered cubic has a symmetry that the hexagonal closed packing doesn't have and you can see it here, so you have because if I remove these two, no one is here, this one you can also see this square, oh yeah, balls, so you can't make a square on this one, you can make it on this one, so you have three by three squares here and vine sauce, it's not good, oh yeah, so actually, if you reorient yourself, you'll get it. you eat. you get a square based pyramid structure, yes, in that direction, and you get a sort of pyramid structure based on a tetrahedral triangle, yes, actually, it's very nice.
There's one last thing that my Atomics Ripoff does, which is actually very nice and we

show

it to you, so take your crystal, let it be the exact things yet - yeah, I just think I have one globe leaving the spare one just let your head be, I can't, oh yeah, I'll just pop these out everywhere because a beaker and you can look, yeah, there's a lot of areas here that maybe weren't Tipitina's first question hmm, I'll have two milks, I really guess It's PI, I ordered the warden, excuse me, the printing on the package takes the wind out of you, so you put lotion on it. -She says on the package, are you going?
I'm going to pack before, so I use it just to get around, yeah, you know, it's amazing, like I put it in giant letters on my hand, okay, just an estimate, an estimate, to reconcile, all of these are more. all of these, how many is a lot, probably 10 in their sets, maybe 100 was three times ten thousand and a thousand roses, yeah, I guess I thought that, by an order of magnitude, I'm better, yeah, the first time I said I was in thousand, but he says yes. It's surprising anyway, I should have gone 100 percent, okay, yeah, I don't have that either.
My conviction is lacking anyway, what you do is for the final trick in the arsenal, you get some wool that I'm not going to have here and you just give it a rub, yeah, and that charges, maybe it's carrying its yeah , but now all these sir, I'm fine, yeah, so they're all slightly charged, which means they would try to get away from each other, so nice, look at that and so what? you end up with a phase boundary, so you have this, so imagine this is the liquid phase and this is the gas phase and there is no equilibrium, there are no transitions from one to the other, it's actually a solid, maybe this be an example of sublimation, so You have two solids again directly to gas and even these guys are a little bit close, yeah, but if they touch you then I'll try it.
I sell. I stole your electrons by saying yes. I apologize, they are mainly or maybe you donated them. electrons who don't know who knows who's keeping score I don't know, I mean, someone will know because someone well, it will be in the comment here. It was really fun to do a video with Steve Malt on his science YouTube channel about lattices and how you can get all these fantastic inclusions and effects in beads, but I thought it would be nice if we also did a video on my channel about some of the math behind it. of the efficiency with which these spheres can be packaged to do so, if If you want to know more about Matt, he actually made that video, if you want to watch it, head over to his channel.
