The new definitions will be based on fixed numerical values of the Planck constant
(h), the elementary charge (e), the Boltzmann constant (k), and the Avogadro constant (NA), respectively.
Scientists meeting at the General Conference of Weights and Measures in Versailles voted on a proposal redefining the kilogram in terms of a physical constant called the Planck constant
. Representatives of more than 50 countries at the General Conference on Weights and Measures unanimously approved new definitions for the International System of Units, known as SI from its French acronym.
and 59 other nationsA adopted a resolution to define the familiar unit of massA in terms of the Planck constant
, an unvarying and infinitesimal number at the heart of quantum physics.
He said he hasn't studied the new approach yet, which involves something in quantum mechanics referred to as the Planck constant
Instead of relating to the mass of a singular physical object, the kilogram will in future be defined in terms of the Planck constant
-- the ratio of quantum energy a frequency of light can carry to that same frequency, or 6.626 x 10-34 joule seconds.
for the electron and Planck-particle cores, where [??] is the reduced Planck constant
. The electron and Planck-particle masses are m and m, respectively.
This equation demonstrates that for the white hole as the world-generating source the mass generation rate has a constant value and the lack of the Planck constant
in it testifies that it is specialized without any need of quantum mechanics.
The new system will tie masses to the Planck constant
instead, allowing for more precise measurements of masses both large and small.
"The Planck constant
was problematic in the past, as there were disagreeing values obtained by different experiments.
In particular, if the choice from (29) is made, then a "fractional Planck constant
" [[??].sub.f] with appropriate dimensions must be introduced in order to render the argument of the exponential in (7) dimensionless.
Quantum physics is a branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant
. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales.
