Dictionary definition of helix

A type of three-dimensional geometric shape that resembles a spiral or a spring.
"The DNA molecule consists of a double helix structure."

Detailed meaning of helix

It is a curve that lies on a cylinder or a cone and is defined by the distance between the curve and the axis of the cylinder or the cone. Helixes can be either "right-handed" or "left-handed" depending on the direction of the twist. Helix can also be used in biology to refer to the shape of DNA molecules, which are composed of two complementary strands that wind around each other in a double helix structure. Helix is also used to refer to a spiral shape in other fields such as mechanics, engineering and physics. Overall, a helix is a three-dimensional geometric shape that is defined by its distance from an axis, and can be found in various fields such as biology, mechanics, engineering and physics.

History and etymology of helix

The noun 'helix' finds its etymological roots in ancient Greek. It is derived from the Greek word 'helix,' which means 'a spiral' or 'a winding curve.' This term in turn originates from the verb 'helissein,' meaning 'to turn around' or 'to twist.' In ancient Greek, 'helix' was used to describe various spiraling or winding forms, from the shape of a shell to the trajectory of a twisting path. Over time, the term made its way into Latin as 'helix' and eventually into English, where it continues to represent a three-dimensional geometric shape characterized by its spiral or spring-like form. Thus, the etymology of 'helix' underscores its historical connection to the concept of spirals and twisting, which remains integral to its meaning as a geometric shape today.
