Product Description

mini-conics.pngShow your appreciation for the beauty of mathematical forms with our cleverly conceived and skilfully crafted Conic Sections Pendant! The striking form of this pendant is only the first of its many charms. Each part of the pendant swivels out to reveal one of the three characteristic curves formed by the intersection of a plane and a cone, the deep significance of which has been known and appreciated since antiquity.

The ellipse, parabola and hyperbola, known collectively as the "conic sections", or "conics", were studied at length by some of the greatest mathematicians of the ancient world. These mathematicians soon discovered a second, significant “characterization” of these curves, which defined them in terms of a point called the "focus" and a line called the "directrix". The relationship of these two features forms a parameter known as eccentricity (or "e"), which is unique to each curve. The range of values for e, which defines each type of curve, is written inside of the appropriate section of the pendant, giving another layer of meaning to this remarkably intricate piece.

The separate parts of this pendant are finished in attractive, and subtly contrasting antiqued pewter and antiqued brass. The adjustable length necklace is made from 3mm x 1mm imitation suede microfiber cord. A unique and eye-catching accessory for anyone who loves mathematics, or who simply appreciates shapes and curves!
