- The
helicoid, also
known as
helical surface,
after the
plane and the catenoid, is the
third minimal surface to be known. It was
described by
Euler in 1774...
- In geometry, a
generalized helicoid is a
surface in
Euclidean space generated by
rotating and
simultaneously displacing a curve, the
profile curve, along...
- An
isotropic helicoid is a
shape that is helical, so it
rotates as it
moves through a fluid, and yet is isotropic, so that its
rotation and drag are the...

family of surfaces, a
catenoid can be bent into a
portion of a
helicoid, and vice versa. The
catenoid was the
