In nature, shapes mostly appear with curves and non-flat faces. It’s only through human creations that shapes with straight ...

They also struggled to create certain geometric shapes like seamless cones and domes. The researchers also found that the pasta best held its 3-D shape when cooked not much longer than 7 minutes.

Is there a term for the shape shown above: a smooth, continuous curve with three axes of symmetry? And if anyone could share the equation for this curve, I would be very grateful.

The 2D pasta morphs into 3D shapes when boiled because each piece is lined with tiny grooves, less than 1 millimetre wide, in particular patterns.

With 3D printed arms of fixed measurements, the depth reading from a set of digital calipers can be used to calculate the radius of a curve.
