Detailed meaning of convex

In geometry, a convex shape bulges outward, with no inward curves or dents. This is in contrast to a concave shape, which curves inward. Convex shapes can be found in various objects, such as lenses, mirrors, and some kinds of jewelry. The convex shape is often used to focus or spread light, as the outward curve causes light rays to diverge or converge. The shape is also important in many engineering and architectural applications, as it can distribute force and weight evenly.

History and etymology of convex

The adjective 'convex,' denoting a surface or shape that curves outward, derives its etymology from the Latin word 'convexus.' In Latin, 'convexus' was used to describe something that was arched or rounded, particularly when referring to the shape of a surface. This term itself is a combination of 'com-' (with or together) and 'vexus,' which is related to 'vehere,' meaning 'to carry' or 'to convey.' Thus, 'convexus' literally means 'carrying together' or 'curved together,' capturing the idea of a surface that bulges or curves outward in a unified manner. Over time, this Latin term evolved into the English adjective 'convex,' which is commonly used to describe shapes such as the exterior of a sphere or a balloon that exhibit outward curvature.
