Cardioid
In geometry, a cardioid (from Greek καρδιά (kardiá) 'heart') is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius. It can also be defined as an epicycloid having a single cusp. It is also a type of sinusoidal spiral, and an inverse curve of the parabola with the focus as the center of inversion. A cardioid can also be defined as the set of points of reflections of a fixed point on a circle through all tangents to the circle. The name was coined by de Castillon in 1741 but the cardioid had been the subject of study decades beforehand. Named for its heart-like form, it is shaped more like the outline of the cross section of a round apple without the stalk. A cardioid microphone exhibits an acoustic pickup pattern that, when graphed in two dimensions, resembles a cardioid (any 2d plane containing the 3d straight line of the microphone body). In three dimensions, the cardioid is shaped like an apple centred around the microphone which is the "stalk" of the apple.

cardioid
A cardioid is a plane curve produced by tracing the path of a chosen point on the perimeter of a circle. This circle is rolling around a fixed circle of the same radius, but it remains in contact with the fixed circle at one point. The term "cardioid" comes from the Greek word for heart, due to the shape resembling a heart. It is also described mathematically as a particular type of mathematical shape described by a specific equation in polar coordinates.
Webster Dictionary
Cardioidnoun
an algebraic curve, so called from its resemblance to a heart
Etymology: [Gr. kardio-eidh`s heart-shaped; kardi`a heart + e'i^dos shape.]
