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:
“Art is the beautiful way of doing things. Science is the effective way of doing things. Business is the economic way of doing things.”
—Elbert Hubbard (1856–1915)
“Science in England, in America, is jealous of theory, hates the name of love and moral purpose. There’s revenge for this humanity. What manner of man does science make? The boy is not attracted. He says, I do not wish to be such a kind of man as my professor is.”
—Ralph Waldo Emerson (1803–1882)
