Boltzmann Constant

The Boltzmann constant (k or kB) is a physical constant relating energy at the individual particle level with temperature, which must necessarily be observed at the collective or bulk level. It is the gas constant R divided by the Avogadro constant NA:

It has the same dimension (energy divided by temperature) as entropy. It is named after the Austrian physicist Ludwig Boltzmann.

Famous quotes containing the word constant:

    I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact.... There is wanting constant and accurate observation with enough of theory to direct and discipline it. But, above all, there is wanting genius.
    Henry David Thoreau (1817–1862)
