A paraboloid refers to a group of solids formed by rotating a flat geometric figure around an axis. In the case of a paraboloid, the rotation of the curve formed by the parabola function.

How can you make a paraboloid of paper?

We suggest you build a model of a paraboloid, with the following characteristics: height 130 mm, base diameter 85 mm. Download a paraboloid net.

Paraboloid assembly scheme:

1. Glue the upper part of the pattern.

2. Connect together the formed domed part.

3. To avoid difficulties and shifting when gluing the base, we recommend that you first glue the auxiliary elements. This will allow you to hold them smoothly when gluing and will create the correct shape of the geometric design.

4. Glue the base.

An example from architecture.

We couldn’t find the buildings that exactly repeated the parabola formula, but nevertheless, in London (United Kingdom) there is a skyscraper with a very unusual shape.

The Mary Eks skyscraper, referred to by locals as the “Cucumber” (or the Gherkin), has no corners, which prevents the wind flow from flowing down and provides natural ventilation. The height of the 41-story building is 180 meters. The diameter of the building at the base is 49 meters, which then expands smoothly, reaching a maximum diameter of 57 meters at the level of the 17th floor. The design then narrows, reaching a minimum diameter of 25 meters.
