Mizukawa found two corn cobs out of nowhere, and then looked at the three of them. He was holding a corn cob and trying to peel off a kernel in the center. However, it could not be successful. He can peel off the corn from both the connecting rod end and the whisker end. Then, he broke the corn cob in half. The corn kernels that come out of the two broken surfaces are even easier. Immediately afterward, he opened a narrow passage with his hands, starting from the end of the connecting rod. Place your hand in the gap between the two rows of corn kernels, and then apply force in the direction of the passage to concentrate on the corn kernels. Then, he peeled off half of the corn cob. Hold the wooden core again in your hand and place it on half a corn cob. By aligning the wooden core with the gap between the two rows of corn on the cob, the corn can be easily peeled off. My question is why corn kernels peel in so many ways, isn't the corn cob formed in one way?

Dueñas said: Of course, there is only one way to form a corn cob, but there are many corn kernels. Have you noticed? The corn on the cob is both a whole and many individuals. In mechanics, when dealing with complex force situations, the particle system is used. Although the corn kernels are stuck to the woody kernel of the corn, and the corn kernels are mostly immovable. The movement referred to here is passive movement, not active movement. This is not the case with the corn kernels at the edges, so the peeling of the corn kernels starts at the end of the connecting rod and the end of the whiskers.

Edge effects. It is the corn kernels at the edges that are most likely to peel off. The reason why spalling can be carried out is that new edges are constantly being created. The three methods used by Mizukawa are essentially to create new edges so that the flaking can continue uninterruptedly.

The whole individual is bisexualized. There is nothing to say about the corn on the cob as a whole, but corn kernels need to be said if they are individuals. The corn kernels are neatly arranged and densely arranged, and they seem to be a single unit. However, we ignore the tiny gaps between the corn kernels. It is this tiny gap that allows the corn kernel to become a semi-independent individual, giving it the opportunity to detach itself from the whole.

Margarita said: I agree with the statement that the whole individual is bisexual. I'm a little bit different, though. Why is there a different way to peel corn kernels? It's about shape. Think of the part of the corn cob as a whole, and it has a shape. In fact, there are many such parts. Thus, the corn cob has a group of shapes. The shapes in the group are revealed one by one, which I call the group appearance. Each shape corresponds to a mechanical system, and external forces are the ones that will destroy the mechanical system. When one mechanical system is destroyed, it becomes another. The mechanical system is related to the shape, so new shapes are created. The peeling is complete until all the shapes of the shape group are revealed.

Liuzifeng: I also agree with the edge effect. Because of this, the propagation of the resulting force can be carried out. Because the propagation of force is arbitrary, it leads to the diversity of spalling methods.

Mizukawa said: Actually, I think the shape explanation is the most accurate. In skinless walnuts, the woody part and the vegetative part are entangled. And this entanglement, in the final analysis, is caused by shape. And they are very difficult to separate. I think this is the best example of the effect of the yin shape on an object.

Intensity. Generally, corn cobs are densely packed, so it is relatively difficult to peel off. And density is actually the inspiration I got from math. When describing diagonal graphics, there is a density rate. Of course, it's not appropriate to summarize the corn cob in terms of density, so I created the density. Density can explain center invariance and edge effects. Of course, when I say density, I mean how many corn kernels there are around a corn kernel. In the case of the same variable, the higher the density of a corn kernel, the easier it is to form a center of invariance. Conversely, if the density is too low, an edge effect occurs.

Well, that's a bit much. I think everyone wants to rest, so that's all for today!
