Avogadro Constant - General Role in Science

General Role in Science

Avogadro's constant is a scaling factor between macroscopic and microscopic (atomic scale) observations of nature. As such, it provides the relation between other physical constants and properties. For example, it establishes a relationship between the gas constant R and the Boltzmann constant kB,

and the Faraday constant F and the elementary charge e,

The Avogadro constant also enters into the definition of the unified atomic mass unit, u,

where Mu is the molar mass constant.

Famous quotes containing the words general, role and/or science:

    “The reputation of generosity is to be purchased pretty cheap; it does not depend so much upon a man’s general expense, as it does upon his giving handsomely where it is proper to give at all. A man, for instance, who should give a servant four shillings, would pass for covetous, while he who gave him a crown, would be reckoned generous; so that the difference of those two opposite characters, turns upon one shilling.”
    —Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    “Given that external reality is a fiction, the writer’s role is almost superfluous. He does not need to invent the fiction because it is already there.”
    —J.G. (James Graham)

    “By an application of the theory of relativity to the taste of readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bĂȘte noire the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”
    —Albert Einstein (1879–1955)
