structure constant उदाहरण वाक्य

Differences in the fine structure constant could also have affected element-building nuclear reactions in stars, which are extremely sensitive to such physical constants.
In the last analysis, they point out, all physical measurements boil down to a few dimensionless constants like the fine structure constant, alpha.
The fine-structure constant is the coupling constant of quantum electrodynamics ( QED ) determining the strength of the interaction between electrons and photons.
This contention has been falsified, given that current estimates of the fine structure constant are ( to 6 significant digits ) 1 / 137.036.
Its discovery spurred and guided the development of quantum electrodynamics, and measurements of the Lamb shift are now used to determine the fine-structure constant.

The electromagnetic fine structure constant, adimensional, is plotted as a horizontal red line jointly with SU ( 2 ) xU ( 1 ) related masses.
The structure constants determine the Lie brackets of elements of the Lie algebra, and consequently nearly completely determine the group structure of the Lie group.
The most precise values of the fine structure constant come from comparisons of the measured and calculated value of the gyromagnetic ratio of the electron.
The structure constants often make an appearance in the approximation to the Baker Campbell Hausdorff formula for the product of two elements of a Lie group.
A change in the fine structure constant could change the rate at which stars burn their fuel and so subtly alter the entire evolution of stars,
