The asterisk ( ), from Late Latin , from Ancient Greek , , "little star", is a Typography, typographical symbol. It is so called because it resembles a conventional image of a star (heraldry), heraldic star. Computer scientists and Mathematician, mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). An asterisk is usually five- or six-pointed in printing, print and six- or eight-pointed when handwritten, though more complex forms exist. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointer (computer programming), pointers, repetition, or multiplication. History The asterisk was already in use as a symbol in ice age Cave painting, cave paintings. There is also a two-thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeri ...

Walnut Street Bridge (Harrisburg)
The Walnut Street Bridge also known as The People's Bridge, was a truss bridge that spanned the Susquehanna River from downtown Harrisburg, Pennsylvania to the West Shore until 1996, when ice floes on the flooded river destroyed three spans of the western part of the bridge, between City Island and the West Shore. Built by the Phoenix Bridge Company in 1890, the remaining bridge is the oldest connecting Harrisburg's downtown and Riverfront Park with City Island. A 2014 Cross-River Connections Study notes that the bridge currently serves as an "important bicycle and pedestrian link between City Island and downtown Harrisburg, connecting the city and the Capital Area Greenbelt to special events on City Island." The bridge was added to the National Register of Historic Places in 1972. History The bridge was built to break the toll monopoly enjoyed by the neighboring Camelback Bridge (now the Market Street Bridge). The Walnut Street Bridge was closed to motor vehicles and convert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record In Pennsylvania
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop ...

Bridges In Cumberland County, Pennsylvania
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

Road Bridges On The National Register Of Historic Places In Pennsylvania
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized ...

Cumberland Valley Railroad Bridge
The Cumberland Valley Railroad Bridge is a currently unused railroad bridge. The bridge links downtown Harrisburg, City Island, and the western suburbs of Cumberland County, Pennsylvania. The bridge was originally constructed by the Cumberland Valley Railroad as part of the mainline from Harrisburg to Hagerstown via Chambersburg. The Cumberland Valley Railroad itself was leased as a subsidiary by the Pennsylvania Railroad. The first crossing, a wooden covered bridge, began construction in the summer of 1836 and opened on January 16, 1839. It was destroyed by fire on December 4, 1844. The four eastern spans remained, but were washed away during the spring floods in 1846. A second crossing in a slightly different location began construction on February 3, 1845, and was completed in 1846. This bridge had an upper deck for railroad traffic, and a lower deck for pedestrian and wagon traffic. Use of the lower deck was discontinued when the bridge was strengthened in 1850. The br ...
