The original online version of this article (Miyashita, T. (2020) Empirical Equation for the Gravitational Constant with a Reasonable Temperature. Journal of Modern Physics, 11, 1180-1192. https://dx.doi.org/10.4236/jmp.2020.118074) unfortunately contains the very important mistakes. The calculated...
is a constant which can be integrated explicitly if needed. Without a loss of generality, we can choose the coordinate system such that the orbit is on the x − yplane, and hence Lz = 0. In this case, S4(ϕ) = 0 and S3(θ) = Lθ. Finally, the equation reduces to (A.9)...
In 1900 the German theoretical physicistMax Planckmade a bold suggestion. He assumed that the radiation energy is emitted, not continuously, but rather in discrete packets calledquanta. The energyEof thequantumis related to thefrequencyν byE=hν. The quantityh, now known asPlanck’s constant, ...
Note that from a point of view of particle physics scattering, a natural expansion parameter would be the coupling constant 𝐺𝑁, or rather, its dimensionless version 𝐺𝑁𝑠−−√𝑞, with s being the invariant mass squared and q being the modulus of the exchanged momentum. Such ...
The surface of constant gravity potential,W0, that closely approximates mean sea level is known as thegeoid. If the constant normal gravity potential,U0, on the normal ellipsoid is equal to the constant gravity potential of the geoid, then the gravity anomaly on the geoid is the difference be...

The result is consistent with the EEP at the two percent level. The experiment can also be viewed as setting a limit on a possible spatial variation of the fine-structure constant 展开 关键词: classical and quantum mechanics, general physics equivalence principle fine structure gravitational fields...
