In Science
In mathematics, many sequences of numbers or of polynomials are indexed by nonnegative integers, for example the Bernoulli numbers and the Bell numbers.
The zeroth law of thermodynamics was formulated after the first, second, and third laws, but considered more fundamental, hence its name.
In biology, an organism is said to have zero order intentionality if it shows "no intention of anything at all". This would include a situation where the organism's genetically predetermined phenotype results in a fitness benefit to itself, because it did not "intend" to express its genes. In the similar sense, a computer may be considered from this perspective a zero order intentional entity as it does not "intend" to express the code of the programs it runs.
In biological or medical experiments, initial measurements made before any experimental time has passed are said to be on the 0 day of the experiment.
Patient zero (or index case) is the initial patient in the population sample of an epidemiological investigation.

Famous quotes containing the word science:
“The well-educated young woman of 1950 will blend art and sciences in a way we do not dream of; the science will steady the art and the art will give charm to the science. This young woman will marry—yes, indeed, but she will take her pick of men, who will by that time have begun to realize what sort of men it behooves them to be.”
—Ellen Henrietta Swallow Richards (1842–1911)
“Our civilization is shifting from science and technology to rhetoric and litigation.”
—Mason Cooley (b. 1927)
