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:

    There was not a tree as far as we could see, and that was many miles each way, the general level of the upland being about the same everywhere. Even from the Atlantic side we overlooked the Bay, and saw to Manomet Point in Plymouth, and better from that side because it was the highest.
    Henry David Thoreau (1817–1862)

    So successful has been the camera’s role in beautifying the world that photographs, rather than the world, have become the standard of the beautiful.
    Susan Sontag (b. 1933)

    It is clear that everybody interested in science must be interested in world 3 objects. A physical scientist, to start with, may be interested mainly in world 1 objects—say crystals and X-rays. But very soon he must realize how much depends on our interpretation of the facts, that is, on our theories, and so on world 3 objects. Similarly, a historian of science, or a philosopher interested in science must be largely a student of world 3 objects.
    Karl Popper (1902–1994)
