A ring is a piece of jewelry that people wear on their fingers. It can also refer to an enclosed space where a boxing or wrestling match or circus performance takes place. The police were investigating the ring that smuggled drugs across the border.
The ring can be worn as a symbol of a marriage or engagement. It can also be a sign of chastity in some religions. The ring can be made of silver, gold, or some other material. Some rings are shaped in the form of a circle while others are oval, square, or rectangular. A ring can have a center stone, diamonds, beads, or other precious gems. Some rings have a decorative pattern or inscription on the surface.
Rings are also used to symbolize friendship or love. Some of these rings are inscribed with the names of people or animals. A ring can also be worn to show support for a cause. A ring that has been carved with a religious message is often worn by people of the same faith. A ring can be used to identify a person as a member of a club, organization, or social group.
An item of jewellery, typically in the shape of a circle, that is worn around the finger as part of an outfit or for decoration. A ring may be worn on either the left or right hand. The word ring can be used as an adjective, such as a ring that is large or a ring that is small. It can also be used to describe an object, such as a ring that is made of brass.
In mathematics, a ring is a set that can be closed under the operations of addition and multiplication, where multiplication distributes over addition. This concept was developed in the 1870s and 1920s with work by Dedekind, Hilbert, Fraenkel, and Noether. It later proved useful in algebraic geometry, invariant theory, and number theory. There are two main classes of rings: commutative rings and non-commutative rings.
A ring that is commutative is one where every element commutes with its complement. For example, ax + yx = axy. Non-commutative rings have been less well understood.
When a statement, discussion, or argument has a ring to it, it means that it sounds true or plausible. For instance, a politician’s claim that they are lowering taxes has a ring of truth to it.
A ring that is too big or too small for the wearer can be uncomfortable. The most common solution is to get the ring resized. The sizing process involves measuring the inner circumference of the ring and fitting it against the finger. There are different sizing systems in use around the world, and many jewelers have their own methods. The style of the ring can also determine whether it needs to be made larger or smaller. Broader bands tend to fit more snugly than thinner ones. Some jewelers advise going up a size for wider rings while others recommend going down a size for thin, delicate rings.
