In engineering, science, and statistics, replication is the repetition of an experimental condition so that the variability associated with the phenomenon can be estimated. ASTM, in standard E1847, defines replication as "... the repetition of the set of all the treatment combinations to be compared in an experiment. Each of the repetitions is called a replicate." Replication is not the same as repeated measurements of the same item: they are dealt with diff… WebExperiment in Physics. 1. As the late Richard Feynman, one of the leading theoretical physicists of the twentieth century, wrote: The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific ‘truth’. (Feynman, Leighton and Sands 1963, p. 1-1)
