'''In silico''' is an expression used to mean "performed on
computer or via
computer simulation." The phrase is coined from the
Latin phrases ''
in vivo'' and ''
in vitro'' that are commonly used in
biology (see also
systems biology) and refer to experiments done in living organisms and outside of living organisms, respectively. Contrary to widespread belief, ''in silico'' does not mean anything in Latin.
History of the term ''in silico''
The expression '''in silico''' was first used in public in 1989 in the workshop "Cellular Automata: Theory and Applications" in Los Alamos, New Mexico. Pedro Miramontes, a mathematician from
National Autonomous University of Mexico (UNAM) presented the report "
DNA and
RNA Physicochemical Constraints, Cellular Automata and Molecular Evolution". In his talk, Miramontes used the term "''In silico''" to characterize biological experiments carried out entirely in a computer. The work was later presented by Miramontes as his
PhD dissertation.

'''In silico''' has been used in
White Papers written to support the creation of bacterial genome programs by the Commission of the European Community. The first refereed paper where "''in silico''" appears was written by a
French team in
1991.

PMID 1784830.] The first refereed book chapter where "''in silico''" appears was written by Hans B. Sieburg in 1990 and presented during a Summer School on Complex Systems at the Santa Fe Institute.

''In silico'' versus ''in silicio''
"''In silico''" was briefly challenged by "''in silicio''", which is correct Latin for "in silicon" (the Latin term for silicon, ''silicium'', was created at the beginning of the 19th Century by
Berzelius) . "''In silico''" was perceived as catchier, possibly through similarity to the word "silicate" . "''In silico''" is now almost universal; it even occurs in a journal title (''In Silico'' Biology: http://www.bioinfo.de/isb/)
The phrase "''in silico''" originally applied only to computer simulations that modeled natural or laboratory processes (in all the natural sciences), and did not refer to calculations done by computer generically.
