Antique in the context of "Flea market"

Authentication (from Greek: αὐθεντικός authentikos, "real, genuine", from αὐθέντης authentes, "author") is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity.

Authentication is relevant to multiple fields. In art, antiques, and anthropology, a common problem is verifying that a given artifact was produced by a certain person, or in a certain place (i.e. to assert that it is not counterfeit), or in a given period of history (e.g. by determining the age via carbon dating). In computer science, verifying a user's identity is often required to allow access to confidential data or systems. It might involve validating personal identity documents.

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. Throughout the 18th and 19th centuries, pendulum clocks in homes, factories, offices, and railroad stations served as primary time standards for scheduling daily life activities, work shifts, and public transportation. Their greater accuracy allowed for a faster pace of life which was necessary for the Industrial Revolution. The home pendulum clock was replaced by less-expensive synchronous electric clocks in the 1930s and 1940s. Pendulum clocks are now kept mostly for their decorative and antique value.

Pendulum clocks must be stationary to operate. Any motion or accelerations will affect the motion of the pendulum, causing inaccuracies, so other mechanisms must be used in portable timepieces.

The hobby of collecting includes seeking, locating, acquiring, organizing, cataloging, displaying, storing, and maintaining items that are of interest to an individual collector. Collections differ in a wide variety of respects, most obviously in the nature and scope of the objects contained, but also in purpose, presentation, and so forth. The range of possible subjects for a collection is practically unlimited, and collectors have realised a vast number of these possibilities in practice, although some are much more popular than others.

In collections of manufactured items, the objects may be antique or simply collectable. Antiques are collectable items at least 100 years old, while other collectables are arbitrarily recent. The word vintage describes relatively old collectables that are not yet antiques.

A collectable, collectible, or collector's item is any object regarded as being of value or interest to a collector. Collectable items are not necessarily monetarily valuable or uncommon. There are numerous types of collectables and terms to denote those types. An antique is a collectable that is old. A curio is something deemed unique, uncommon, or weird, such as a decorative item. A manufactured collectable is an item made specifically for people to collect.

A clockmaker is an artisan who makes and/or repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches. Clockmakers must be able to read blueprints and instructions for numerous types of clocks and time pieces that vary from antique clocks to modern time pieces in order to fix and make clocks or watches. The trade requires fine motor coordination as clockmakers must frequently work on devices with small gears and fine machinery.

Originally, clockmakers were master craftsmen who designed and built clocks by hand. Since modern clockmakers are required to repair antique, handmade or one-of-a-kind clocks for which parts are not available, they must have some of the design and fabrication abilities of the original craftsmen. A qualified clockmaker can typically design and make a missing piece for a clock without access to the original component.

An alternative investment, also known as an alternative asset or alternative investment fund (AIF), is an investment in any asset class excluding capital stocks, bonds, and cash.

The term is a relatively loose one and includes tangible assets such as precious metals, collectibles (art, wine, antiques, vintage cars, coins, watches, musical instruments, or stamps) and some financial assets such as real estate, commodities, private equity, distressed securities, hedge funds, exchange funds, carbon credits, venture capital, film production, financial derivatives, cryptocurrencies, non-fungible tokens, and Tax Receivable Agreements. Investments in real estate, forestry and shipping are also often termed "alternative" despite the ancient use of such real assets to enhance and preserve wealth. Alternative investments are to be contrasted with traditional investments.

Taonga or taoka (in South Island Māori) is a Māori-language word that refers to a treasured possession in Māori culture. It lacks a direct translation into English, making its use in the Treaty of Waitangi significant. The current definition differs from the historical one, noted by Hongi Hika as "property procured by the spear" [one could understand this as war booty or defended property] and is now interpreted to mean a wide range of both tangible and intangible possessions, especially items of historical cultural significance. It has been changed to suit agendas. The 1820 Grammar and Vocabulary of the Language of New Zealand by Cambridge University professor Samuel Lee defined taonga as property procured by the spear. The second dictionary, was the Dictionary of the New Zealand Language by William Williams, published in 1844 four years after treaty was signed. This simply defined taonga as property.

Tangible examples are all sorts of heirlooms and artefacts, land, fisheries, natural resources such as geothermal springs and access to natural resources, such as riparian water rights and access to the riparian zone of rivers or streams. Intangible examples may include language and spiritual beliefs. The concept of taonga can also transcend into general New Zealand culture and non-Māori items; for example, the Ranfurly Shield is recognised as a taonga amongst the New Zealand rugby community.
