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.
For example, a curve that, when rotated, forms a vase or a light bulb. Such tools for creating bodies of revolution are very popular with those who work in 3D-design programs.
But from a mathematical point of view, the following geometric solids of revolution are of primary interest to us:
How to make a cylinder of paper?
How to make a cone of paper?
How to make a paraboloid of paper?
How to make a paper hyperboloid?
How to make a paper torus?
To compare the resulting models' sizes, we tried to assemble them on the same surface together with prisms from the Magic Edges #16 issue.
It turned into a whole mathematical city of paper that fits on the table!
