Focus on practice

Introducing the regular polyhedra that have been of concern to different mathematicians, scientists and artists throughout history. Among them, the "Platonic solids" are the most famous, and there are also "semi-regular polyhedra", "dual polyhedra", etc. Lecturer Yu learned from Asheer's work "Gravity"

We set out to discuss "How to make this actual model?" Later, we cooperated with the team of Dutch scholar Rinus to develop different layouts, using laser cutting, and designed the paper pieces to be "stuck and knotted" so that they would not Polyhedrons can be assembled using only glue, and the stuck corners happen to be the vertices of the dual polyhedrons.

Thoughts and feedback:

In the past, when I was learning sketching, I would start by drawing plaster statues, starting with cubes, tetrahedrons, pyramids, dodecahedrons, etc. Later I would start drawing spheres, and even advance to portraits, so I am no stranger to three-dimensional images of polyhedrons. And when I was in elementary school, I had to do various polyhedra in math class.

But what I heard today was beyond the scope of my knowledge. I couldn’t figure out “semiregular polyhedron” and “dual polyhedron” alone. The mathematics teachers present should be familiar with my reaction, because students are like this ~ these geometric figures Let students assemble through combinations, and students will definitely be more interested in learning.

In addition, I thought of giving students some basic templates so that they can design, change colors or study more complex polyhedra. This should stimulate more creativity and interest in mathematics.
