Varying Fine Structure Constant?
This question may have been asked a thousand times on here so please diredt me to the relevant post if that is the case. During a particle physics lecture I was told that although the fine structure constant is widely regarded as being 1/137 at normal lab energies, it seems to tend towards...- sor2char

Nuclear efficiency and the fine structure constant?
I find in Martin Rees "Just Six Numbers" that hydrogen undergoes fusion to helium with a mass energy conversion of .007, that is, the mass of the helium formed is less than the mass of the hydrogen by this ratio. Is it a coincidence that this number is the same as the fine structure...- nightcleaner

An exact expression for the fine structure constant
Just for the record: \ \alpha^{-\frac{1}{2}}\ +\ \alpha^\frac{1}{2}\mu\ =\ e^{\pi^2/4} Where \alpha, the fine-structure constant = 1/137.03599911 (46) and \mu=1+\frac{\alpha}{2\pi} is Schwingers first term of the electrons magnetic moment anomaly which is a function of \alpha as...- Hans de Vries

Coulomb's Force Law and the Fine Structure Constant - Variance?
*** PART I. *** THREE QUESTIONS ON "COULOMB'S LAW" The value of the constant "K" in what appears to be the "ORIGINAL" Coulomb's Law depends upon the nature of the medium. [ K = 1/4pi*epsilon ] where epsilon is the "absolute permittivity of the medium". In many modern books, I...- what_are_electrons

Fine structure constant changes over time
In this month's edition of the "New Scientist" magazine (July 2004), there is an article which says that the fine structure constant alpha was smaller in the past ( alpha = e^2/ hbar c), and the speed of light was greater. Since the speed of light can be given by the ratio of E/B (electric...- kurious

Fine structure constant has geometrical nature
In the previous theme I spoke, that tangential energy of the dipole of speed is proportional to its square. Accordingly, tangential energy of radial resonance oscillations of the energy ring is proportional to the total square of all dipoles of speed in the ring. See file "dipole of speed.pdf"...- vlamir
