Postcard
A postcard or post card is a piece of thick paper or thin cardboard, typically rectangular, intended for writing and mailing without an envelope. Non-rectangular shapes may also be used but are rare. In some places, one can send a postcard for a lower fee than a letter. Stamp collectors distinguish between postcards (which require a postage stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed and sold by a private company, individual or organization, a postal card is issued by the relevant postal authority (often with pre-printed postage). Production of postcards blossomed in the late 19th and early 20th centuries. As an easy and quick way for individuals to communicate, they became extremely popular. The study and collecting of postcards is termed ''deltiology'' (from Greek , small writing tablet, and the also Greek ''-logy'', the study of). History 1840 to 1864 Cards with messages have been sporadically created ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean High Water
A chart datum is the water level, water surface serving as origin (mathematics), origin (or coordinate surface) of depth (coordinate), depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. Common chart datums are ''lowest astronomical tide'' (LAT)Australian Bureau of MeteorologNational Tide Centre Glossary(retrieved 30 April 2013) and ''mean lower low water'' (MLLW). In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart. However, it is necessarily an equigeopotential (a water "level surface"): the chart datum is tilted across smaller to larger tidal range regions; in rivers, it is a sloping and undulating surface following the low stage (hydrology), stage. Definitions The following tidal phases are commonly used in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone (architecture)
A keystone (or capstone) is the wedge-shaped stone at the apex (geometry), apex of a masonry arch or typically round-shaped one at the apex of a Vault (architecture), vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults (such as quasi-domes) keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern (architecture), lantern. A portion of the arch surrounding the keystone is called a Crown (arch), crown. Keystones or their suggested form are sometimes placed for decorative effect in the centre of the flat top of doors, recesses and windows, so as to form an upward projection of a lintel, as a hallmark of strength or good architecture. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, ...
