ab initio

Ab initio (Latin; abbreviated: a i ) means " from the beginning" and is often used in the field of science:

  • In chemistry, for example, an ab initio synthesis means the production (synthesis) of a chemical compound from basic chemicals.
  • In physics, a initio calculation is performed without From the results of the measurement. The difference between an ab initio calculation and an evaluation of the measurement results may indicate errors in the experimental procedure, allowing a more accurate determination of the inputs used in the calculation parameters or show a previously unrecognized effect.
  • In quantum chemistry and quantum mechanics is meant by ab initio solving the Schrödinger equation using only natural constants. When using measured values ​​are in contrast to ab initio methods are so-called semi- empirical calculations.
  • In aviation is meant by ab initio flight training " from the beginning ", ie from the pedestrian to the line pilots.
