Nanopond (software)
Nanopond may refer to: *a billionth of a pond A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from ... *a digital organism simulator; see Artificial life#Program-based {{Disambig ...

Nano-
Nano (symbol n) is a unit prefix meaning "one billionth". Used primarily with the metric system, this prefix denotes a factor of 10−9 or . It is frequently encountered in science and electronics for prefixing Unit of measurement, units of time and length. ;Examples: * Three gold atoms lined up are about one nanometer (nm) long. * If a Marble (toy), toy marble were scaled down to one nanometer wide, Earth would scale to about wide. * One nanosecond (ns) is about the time required for light to travel 30 cm in air, or 20 cm in an optical fiber. * One nanometer per second (nm/s) is approximately the speed that a fingernail grows. The prefix derives from the Greek (Latin ), meaning "dwarf". The General Conference on Weights and Measures (CGPM) officially endorsed the usage of ''nano'' as a standard prefix in 1960. When used as a prefix for something other than a unit of measure (as for example in words like "nanoscience"), nano refers to nanotechnology, or means "on a scale o ...

Pond (unit)
The kilogram-force (kgf or kgF), or kilopond (kp, from la, pondus, lit=weight), is a non-standard gravitational metric unit of force. It does not comply with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to .NISTbr>''Guide for the Use of the International System of Units (SI)''Special Publication 811, (1995) page 51 Similarly, a gram-force is , and a milligram-force is . Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is not accepted for use with SI. History The gram-force and kilogram-force were never well-defined units until the CGPM adopted a ''standard acceler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Organism
A digital organism is a self-replicating computer program that mutates and evolves. Digital organisms are used as a tool to study the dynamics of Darwinian evolution, and to test or verify specific hypotheses or mathematical models of evolution. The study of digital organisms is closely related to the area of artificial life. History Digital organisms can be traced back to the game Darwin, developed in 1961 at Bell Labs, in which computer programs had to compete with each other by trying to stop others from executing . A similar implementation that followed this was the game Core War. In Core War, it turned out that one of the winning strategies was to replicate as fast as possible, which deprived the opponent of all computational resources. Programs in the Core War game were also able to mutate themselves and each other by overwriting instructions in the simulated "memory" in which the game took place. This allowed competing programs to embed damaging instructions in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
