Urban parkAn urban park or metropolitan park, also known as a city park, municipal park (North America), public park, public open space, or municipal gardens (UK), is a park or botanical garden in cities, densely populated suburbia and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company.
City-stateA city-state is an independent sovereign city which serves as the center of political, economic, and cultural life over its contiguous territory. They have existed in many parts of the world since the dawn of history, including ancient poleis such as Athens, Sparta, Carthage and Rome, and the Italian city-states during the Middle Ages and Renaissance, such as Florence, Venice, Genoa and Milan. With the rise of nation states worldwide, there remains some disagreement on the number of modern city-states that still exist; Singapore, Monaco and Vatican City are the candidates most commonly discussed.
Central ParkCentral Park is an urban park between the Upper West Side and Upper East Side neighborhoods of Manhattan in New York City, United States. It is the fifth-largest park in the city, containing , and the most visited urban park in the United States, with an estimated 42 million visitors annually . The creation of a large park in Manhattan was first proposed in the 1840s, and a park approved in 1853. In 1857, landscape architects Frederick Law Olmsted and Calvert Vaux won a design competition for the park with their "Greensward Plan".
Open-source hardwareOpen-source hardware (OSH) consists of physical artifacts of technology designed and offered by the open-design movement. Both free and open-source software (FOSS) and open-source hardware are created by this open-source culture movement and apply a like concept to a variety of components. It is sometimes, thus, referred to as FOSH (free and open-source hardware). The term usually means that information about the hardware is easily discerned so that others can make it – coupling it closely to the maker movement.
Visual systemThe visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species to "build a representation" of the surrounding environment.
Visual cortexThe visual cortex of the brain is the area of the cerebral cortex that processes visual information. It is located in the occipital lobe. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex. The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 (V1), Brodmann area 17, or the striate cortex.
Open textbookAn open textbook is a textbook licensed under an open license, and made available online to be freely used by students, teachers and members of the public. Many open textbooks are distributed in either print, e-book, or audio formats that may be downloaded or purchased at little or no cost. Part of the broader open educational resources movement, open textbooks increasingly are seen as a solution to challenges with traditionally published textbooks, such as access and affordability concerns.
