      @kruose Mean, median and mode concepts are easy to grasp and taught in high school, yes, but that’s like saying understanding 1+1 lets you understand integration. I don’t believe high school mathematics teaches you curvature or what “zero mean” means when used to describe curvature, unless you take some sort of advanced class. I understand that jargon can seem simple when you have the knowledge already, but this one is seriously not in the standard syllabus. I’d be wondering where you live if they teach you that in high school

      the soap covers like the least area it has to to connect to the edges like "the path of least resistance"!! So if the shape of the soap matches the shape, than its like the edges were "filled in" with the SMALLEST surface area possible

      imagine bending a wire to match the ridges/edges of one of the eggs. you dip it in soap. the soap matches the form of the egg (the part missing from the wireframe) because that substance is essentially a minimal surface calculator

      Doesnt show in the full video either, but I think the reason is that the egg is is the 3D demo of minimal surface, which is the equivalent of a bubble form. Dipping the egg might look cool but might also cause confusion. Like if he 3D printed the cube's bubble so he could show it without having to be careful, it would be besides the point to then dip that in soap.

    • Daniel Yuan
      Daniel Yuan 29 days ago +2

      Because it's hard to pull off and the demonstration is hard to see. That's why he gave a demo on the cylinder and said to imagine the same thing on the egg.

  • BritishBoy
    BritishBoy 3 months ago +2446

    Am I the only one that got this?
    If I’m not mistaken he was explaining that a good way of testing if something is minimal surface is by bending a wire frame around them and dipping them in soap. If the bubble film creates the exact shape of the object that you wrapped the wire around, then it is minimal surface.
    The can was not minimal surface because the wireframe produced a bubble film that was bowed inwards (not cylindrical).
    The reason the egg is minimal surface is because no matter where you wrap the wire around on the egg’s weird swoops and curves and create a closed loop, you will always have the shape of the egg (or at least the section you wrapped wire around) if dipped in bubble juice. If the egg was just made out of a grid of squares then wrapping a wire around it wouldn’t give you the true shape of the egg.
    Maybe this helped? This is what I understood of it anyways 😅

    For those who don't understand, just focus on the bubble part.
    It's like displacement but for 3D object, and bubbles which are created with soap film is know to shape itself around a loop with the fewest amount as possible, this help find the minimal amount of surface needed for an object.

      The bubbles try to have minimal surface for stability, and efficiency. Therefore one can use bubbles to see the minimal surface of material within a loop. The can is not minimal surface, because instead of going inwards like the bubble, it goes straight. The egg is made to always have the same form as the bubble if you make a loop around any of the forms on the egg.

    Step 1: Take an object
    Step 2: Draw a closed shape on it(triangle, circle, bean, whatever)
    Step 3: Bend a wire frame to match the shape you’ve drawn.
    Step 4: Dip wire frame into soap
    Step 5: If the soap fits perfectly inside the wireframe. Bam. thats the minimal surface
    If the soap doesn’t fit the wire frame, then its not the minimal surface.
    Extra: No matter what shape you make out on the surface of the egg, if you dip your wireframe in soap it will fit inside the wireframe perfectly
    Hope this helps

  • Rex
    Rex 3 months ago +2

    For all my brothers/sisters confused about the explanation, I got you. Basically a soap film possesses surface tension and associated surface energy. So the film tries to contract as to minimise its surface area which in turn minimises its surface energy. That is why rain drops are completely spherical ( ignoring gravity and other forces ) because for a given volume sphere has minimum surface area : )

  • Sovenate
    Sovenate 3 months ago +1

    So basically, since the can surface isn't the minimum surface, you see the bubble in the wire concave (i.e. fold into the wire). That being said, he if did the same thing to the egg anywhere on the surface, the bubble would become level with the wire itself, compared to being concaved with the can.

  • David Bond
    David Bond 3 months ago

    The surface area is less with the bubble because it curved in (around a corner), whereas the can is flat which makes it have more area.
    So all the points curving in on the egg is actually less than if it was going over the egg normally, for the different shapes added on the normal egg surface.
    That's what I could get from this.

  • Deep
    Deep  3 months ago

    The wire frame acts as a framework for the bubble. The bubble bends inwards and is not flat on the wire, this shows that the cylinder's surface is not optimal surface as it is not the most minimal surface area. Why soap water, it creates a film with high surface tension and hence gives the minimal surface area. Why that shape for the drawing, it's because he is taking a random part of the can. In case of batwing egg, every such area has minimal surface area. Hope this clears up some confusion.

  • Adrian Cam
    Adrian Cam 3 months ago

    A minimal surface seems to be that soap-film that forms with a closed loop. With his can example, a can can have a closed loop on it, but the shape of the can in that loop (cylindrical) does not match the shape of the soap-film (curved, minimal area).
    I'm guessing with the egg, if you were to form a loop anywhere and then dip that loop in soap, the pattern you'd see on the soap film would match the pattern on the eggs surface. Unlike the can, where the objects surface did not match the soap-film.

  • SemenTheSailor
    SemenTheSailor 3 months ago

    Ok I’m going to try and explain. Minimal surface are is the smallest amount of surface area to cover a shape. In 2D it’s pretty easy, you’d just colour in the area of the shape. But in 3D it gets weird. Imagine you have a circle on a piece of paper, now curl the paper so the circle is in a taco shape. Now we want to find the smallest surface area possible for our taco shape. If we just coloured in the circle that wouldn’t be the smallest amount of surface area as we have a whole new dimension to make shortcuts with. He essentially made a slightly deformed version of our taco shape with can. The cool part is that bubble solution will always find a shapes minimal surface area due to surface tension. So when he dips our taco shape into the bubble solution we see it makes a sort of curvy Pringle shape. That shape is was the minimal surface area of our taco.
    Those eggs were 3D printed representations of irregular shape’s minimal surface area.
    Also, it proves that Pringles are specifically designed to use as little ingredients possible to take up the most space.

  • Chirag Rastogi

    It's quite interesting because the minimal surface area problem is precisely the type of problem a Quantum Computer can solve. That would help us with things like better shapes for structures or something as cool as the geometry of black holes!

  • Mat
    Mat 3 months ago

    It took me two watches to understand that. So it means within the defined shape, the bubble conforms and basically takes “shortcuts” to make its shape making its minimal surface form. The starting shape that was taken from the can is more of an inefficient way of making the shape and when you put a bubble on it, it conforms to the minimal surface area (if you could say) it can create with that shape that is defined.

  • foreshadowing_panda
    foreshadowing_panda 3 months ago

    "In mathematics, a minimal surface is a surface that locally minimizes its area. This is equivalent to having zero mean curvature The term "minimal surface" is used because these surfaces originally arose as surfaces that minimized total surface area subject to some constraint. Physical models of area-minimizing minimal surfaces can be made by dipping a wire frame into a soap solution, forming a soap film, which is a minimal surface whose boundary is the wire frame. However, the term is used for more general surfaces that may self-intersect or do not have constraints. For a given constraint there may also exist several minimal surfaces with different areas (for example, see minimal surface of revolution): the standard definitions only relate to a local optimum, not a global optimum."------Wiki... and no, this wiki didnt help me either😅🤷‍♀️

    It's about the missing space, by minimal surface he means that there is a space defined by a closed loop, therefore creating the minimal surface. If you look closely, you'll see that the egg actually has bean-like shapes that are as small as possible so the egg keeps standing.

  • Zepper Man
    Zepper Man 3 months ago

    Basically, say you have two points.
    A straight line between those points would be the minimal distance. Any deviation would be above minimal.
    If you have three points all on the same plane, a flat triangle with 3 straight lines would be minimal. Any curvature along the edges or z axis would be above minimal.
    In other words, any point along the minimal distance will have an equal sum distance between all 3 points that cannot go any shorter.
    The bubble defines where those points are.

  • Jader Alacevich

    The rounded bulges the egg and can shape aren't a minimal surface because when a portion of that shape is tested with the soap film (a soap film covering the surface of the shape is known to be a minimal surface area), the shape doesn't resemble the same shape of the tested shape. The soap film doesn't bulge out as the can does.

    I believe minimal surface is the minimal distance between two sides. So the minimal surface formed by the bubble is the closest point between the two and isn't actually the shape of the can. So the eggs are what minimum distance between certain points on the egg would look like.
    But I could be wrong.

    For people who don't completely understand, the soap will pull itself as tight as possible. The film will then be put in a state where it is taking the least amount of area, because any extra is pulled tight. It's the same principle as pulling a string taut, but in three dimensions

  • Doorstep Mushroom
    Doorstep Mushroom 3 months ago

    Delwyn 3 months ago

    I think everyone is hung up on the shape of the egg and that's where the confusion lies. From my understanding, the minimal surface is just a way to test if a shape has a minimal surface or not (by wrapping a wire on it and dipping it in soap). The resulting shape that the soap bath would give you would be the minimal surface area that you could create based on the original shape.
    Now, the egg looks the way it does because the wire wrapped on it is randomly done (well, at least not uniformly) in enclosed loops which creates minimal surfaces for parts of the egg (as it would be difficult to do otherwise if you consider the shape of an egg).
    The "test" that Action Lab was mentioning is a test to see whether the enclosed loop sections of the wire would actually create minimal surfaces on the egg.

  • Phillip Greer
    Phillip Greer 3 months ago

    Ok, so the soap will fill in the shape in the way that requires the least surface area, and there for is the most efficient. So the ring with the can proved not to be the most efficient. But if you did this with the egg. The soap would perfectly match.

  • Huw Follant Year L6
    Huw Follant Year L6 3 months ago

    Ok so basically it's the least amount of surface area the bubble mixture takes up when spread over that area. The way it sits is not the same as the wire taken from the can drawing because the wire has a higher 2D surface area than the minimum the bubble mixture can form. The egg is minimal surface because if the wire was made into any shape on its surface, the bubble mixture would conform exactly to its twists and turns with a flat surface.

  • Ashutosh Singh
    Ashutosh Singh 3 months ago +1

    It's a very clever and very very easy way to understand minimal surface area.
    Bubbles or soap film or any liquid tries to attain minimum surface.
    You proved that for cylindrical shape of can the minimal surface is not same as there is some inward inclination of soap film. Now for egg when you would use same wire a similar minimum shape would be observed.
    Man you have my respects.

If the batwing egg was submerged in water, surely more of the surface would be touching water than a normal egg?

  • lovely luna ♡
    lovely luna ♡ 3 months ago

    Ok I don't get the egg part but with the can part, he's basically saying that the "minimal surface area" is represented by the shape of the bubble solution when you dip the wire in it. So, he wrapped the wire around the can to see what the minimal surface area SHOULD be for a can of that shape and size, but we can see how the bubble solution curves inwards on itself instead of being a straight line like the wall of the can is, so the can does not have the minimal surface area because it doesn't match the shape of the bubble solution. I have a hard time understanding how it connects to the egg, though... If you wrap the wire around the egg and dip it in bubble solution, it looks like the weird shape of that egg?? That's what it sounds like he's saying but that doesn't make any sense at all. I wish he'd demonstrated that last part 😂
    Edit: Watched again and I think I get it! You'd have to wrap the wire around the insides too, since the egg shape has a bunch of holes in it, it would be a really complicated way to wrap the wire around it but if you DID manage to get a wire loop in the shape of the egg, the full shape of the egg would end up being the exact shape of the bubble solution. You can see how parts of the egg curve inward on itself, kind of like a halfpipe rather than having straight smooth walls like the soda can, which we saw the bubble solution also did the halfpipe thing so it makes sense that the egg could match that shape.

    By the way, is the "Batwing Egg" a natural or man-made thing? I'm assuming the latter so far. It looks pretty interesting.

      The mathematical shape of the batwing egg is discovered. But I'm pretty sure this doesn't appear in nature.

    On the wire he made around the can, the bubble film indents into where the can would be. whereas if he dipped the wire after wrapping the wire around the egg, the bubble film would match the egg’s surface

    What he's trying to explain is that the cans curved cylindrical shape has more surface area than the same shape in a bubble because the bubble will naturally take the form of the least surface area, hence the curve in the bubble.

  • PROkill5701C

    If u take 2 rings and place them parallel to each other in a distance. Then wrap a cloth (non-elastic) around it, so that its shape is a cylinder (hollow)
    Then take a string and put around the cloth in the middle of the cylinder and tight it.
    Now when u tight it, the cylindrical shape will change. But the cloth should expand (or the distance between the rings should decrease) to change the shape.
    Then how it becomes a minimal surface ?

  • EchoGamer 16

    Seems to be some confusion so let’s see if I can simplify this.
    The closed loop drawn on the item is just the shape made out of the bent wire. Minimal surface area is the absolute least amount of space that the surface could occupy.
    The soap solution helps to check for minimal surface area because it will automatically create tension that eliminates ang excess surface.
    Because the can is a cylinder, and a rigid one, the shape of the can is not minimal surface area, as demonstrated by the comparatively warped shape of the soap.

    Yeah not the same as minimal surface area (which has to be qualified as per volume or per mass). The most minimum surface area for a 3d object (per enclosed volume) is always a sphere…

  • John Derat
    John Derat 4 months ago +5

    For those who don't understand, minimal surfaces are surfaces with the least amount of surface area. Soap will always try to make minimal surfaces. And these batwing eggs have minimal surfaces all over, meaning that if you take a wire and bend it to any shape on one of these eggs, the shape that the soap will make will match the batwing egg perfectly.

    You are conflating actual surface area with minimum energy surfaces. These are both calc-3 subjects. Minimal surface energy does not equal minimum surface area. Hope this helps!

    How does something have a minimal surface if it doesn’t take the shortest distance between two points? You’ll need more material to cover an arc between two points 1m apart on the ground vs. two points 1m apart on flat ground.

  • Fabian Sanchez
    Fabian Sanchez 3 months ago

    Here’s an explanation. Think of how on a 2d plane, the most efficient path from one point to another is a straight line, you know this the most efficient because the line it would produce would be shorter in length than one that had any curves. A minimal surface would take this principle into the 3D world we perceive, the shape formed on the can (which to remind you is meant to be imagined as filled in, like how he drew it on the can) is not minimal because each point on that line on the can he drew does not reach every other point on the can in the most efficient path, thusly it is not minimal. The reason the soap exposes minimal surface is because the surface tension pulls it into the most efficient form naturally.

    So basically bubble solution covers the area of a perimeter more idealy than a cylinder, the batwing egg mimics the patterns of the bubble solution, this is my best guess and explanation.

  • Joseph Peters
    Joseph Peters 3 months ago

    So the wire frame is the object and the soap surface is the (material) (metal,soap) that’s required to get to the other side of the object aka the minimum amount of material to connect the sides of the object and the soap finds that small amount because of then tensile strength pulling on the soap

  • John Mobley

    To me it was pretty obvious why it’s a minimum surface egg. Well I THOUGHT wrong. I thought There’s a lot more of the egg that would be there then if it were a normal leg but then but it has the least amount of surface area touching the surface. And I left confused.

  • Hyper Cube
    Hyper Cube 3 months ago

    When he draws the shape on the can clindar can fills the shape with a surface (inside the blue circle)
    When he bends the wire to match the shape he drew and dipped ir in the soap the soap took the shape of a minimum surface note that it was concave (curved inward). Not matching the Curved surface of the can which was convex (Curved outward)
    So on the egg if you draw a closed shape on it, inside that shape will be minimal surface. And if you folded a wire to match the shape you drew on the egg, dipped it in soap, the bubble in the wire would line up with the surface of the egg.
    I'm not sure if I got the explanation right but I think that's what the video is trying to convey.
    I'm not sure what exactly a minimal surface is in the context of math and calculating it though.
