Feb 28, 2024 · Soft cells are described as natural tiles with curved edges—a stark contrast to the mathematical solutions for creating tiling shapes. The soft cells then smoothly deform into tiles and work in...
2 days ago · Mathematicians have found a new kind of shape with connections to nature and art. By Elise Cutts. Photographs of 3D-printed shapes show soft cells derived from space filling polyhedra. Blue is ...

Here is a question from 2001 to start us off: We had previously answered several questions that touched on this, but had not really addressed the issue. I took the question, which was the start of a “career” of specializing in this question: In other words, I did not find a proper definition of “edge” that fits this context, but it is reasonable to...
A year later, we got this question along similar lines: Again, the book is giving definitions suitable for a polyhedron, but applying them inconsistently to non-polyhedra. I responded again, after referring to that previous answer: I later discussed the “vertex” of a cone here:
A month later we got yet another question about this, which got a long answer: I answered first, again having referred to the previous answer as background: If you are going to use the word “edge” in talking about a cone, you must use a definition that is appropriate, just as I previously commented about needing some word that describes the curved ...
But this discussion went further, outside of Ask Dr. Math. Doctor Sarah added this: She copied in two responses to the question. The first, by Walter Whiteley, dug into issues related to Euler’s formula, which I discussed last week, and will talk about more next time. I will just quote pieces of it that relate most directly to our present issue of ...
I’ll close with a question from a 12-year-old in 2008: I took this as a chance to put together a larger perspective on these questions. In our experience answering random questions with little or no stated context, it quickly becomes clear that context determines what definitions apply, so we can’t answer effectively without that background. We als...
Jul 16, 2019 · Faces are the flat or curved surfaces that make up the outside of a 3D shape. Edges are the lines where two faces on a 3D shape meet. Vertices are the corners of a 3D shape formed where two or more edges meet. For example, a cube has 6 faces, 12 edges and 8 vertices.
Sep 25, 2024 · Even though many shapes have straight edges and lines, some shapes, like hemispheres, have curved edges. What are Vertices? In geometry, a vertices are point of intersection of two or more curves, lines, or edges. They are represented as points and denoted by letters such as A, B, C, D, etc.
Jan 16, 2024 · Curved Shapes: Shapes like spheres and cylinders have curved surfaces without edges or vertices. Flat Shapes: These are shapes with flat surfaces, like cubes and pyramids, which have flat faces, edges, and vertices.
