# Project News Polyhedr.com in July 2020

"Your Graduation" No. 6 helped me create a 3d model of the 14th form of the icosahedron. I did not stop there ...

Look at the photo. This is the only one of its kind model of a polyhedron made of concrete - the Fourteenth stellated form of an icosahedron. The description of the model is in the book of Magnus Wenninger. The diameter of my model is 1330 mm. "

MODEL COORDINATES

56*53*16.76" N
60*52*56.43" E

And at the moment, I am engaged in the manufacture of the Szilassi polyhedron.

# Archimedes, a scientist from Ancient Greece, discovered thirteen types of polyhedra, now called Archimedean solids, referred to as semi-regular polyhedra.

### Nets solids of revolution. How to make pdf template

What happens if a flat geometric shape, such as a rectangle, begins to rotate rapidly relative to one of its sides?
We create a new geometric solid in space by rotation.

### Merkaba - energy polyhedron

According to some spiritual teachings, a polyhedron already familiar to us — a compound of two tetrahedra (stellated octahedron) — is not just a geometric form. This form is endowed with powerful energy and maybe even supernatural properties.

# One can specify the following mathematical characteristics in each of the five Platonic solids:

1. The radius of the sphere circumscribing the polyhedron;

2. The radius of the sphere inscribed in the polyhedron;

3. The surface area of the polyhedron;

4. The volume of the polyhedron.

### The star of hope

A star is an image of divine idea and will; due to them, our Light and Universe were created and started to exist in Space.

# In the natural environment, regular polyhedra can be found in the form of crystals (minerals).

The form of the tetrahedron is transmitted by antimony sodium sulfate.

### Divide the icosahedron (into parts)

Is it possible to make up an icosahedron using more simple polyhedra?

# With the same pattern repeating on each polyhedrons face, it is possible to create an alternating combination of patterns on a three-dimensional geometric solid.

### Prince Rupert's Cube

IIn issue 25 of the Magic Edges, we noticed that we get a cross-sectional cut at the cut point by cutting a cube with a plane.
And this geometric shape will change depending on the angle of inclination of the plane.
