Did You Know?

"In silico" literally means "in silicon" in New Latin, and is a nod to the importance of silicon in the creation of computer chips. (The same nod is given in the name "Silicon Valley.") "In silico," which dates only to the early 1990s, is modeled on and often contrasted with two similarly-structured terms, both of which date to the pre-computer days right around the start of the 20th century. "In vitro" means "outside the living body and in an artificial environment." (In New Latin "in vitro" means "in glass.") "In vivo" translates as "in the living" in New Latin, and is used in English to mean "in the living body of a plant or animal."
