Data storageData storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data.
Development of the nervous systemThe development of the nervous system, or neural development (neurodevelopment), refers to the processes that generate, shape, and reshape the nervous system of animals, from the earliest stages of embryonic development to adulthood. The field of neural development draws on both neuroscience and developmental biology to describe and provide insight into the cellular and molecular mechanisms by which complex nervous systems develop, from nematodes and fruit flies to mammals.
Long DepressionThe Long Depression was a worldwide price and economic recession, beginning in 1873 and running either through March 1879, or 1896, depending on the metrics used. It was most severe in Europe and the United States, which had been experiencing strong economic growth fueled by the Second Industrial Revolution in the decade following the American Civil War. The episode was labeled the "Great Depression" at the time, and it held that designation until the Great Depression of the 1930s.
Coordinate timeIn the theory of relativity, it is convenient to express results in terms of a spacetime coordinate system relative to an implied observer. In many (but not all) coordinate systems, an event is specified by one time coordinate and three spatial coordinates. The time specified by the time coordinate is referred to as coordinate time to distinguish it from proper time.
Economic depressionAn economic depression is a period of carried long-term economic dow that is the result of lowered economic activity in one major or more national economies. Economic depression maybe related to one specific country were there is some economic crisis that has worsened but most often reflexes historically the American Great Depression and similar economic status that may be recognized as existing at some country, several countries or even in many countries.
