THE fundamental constants of physics, such as c the velocity of light, h Planck's constant, e the charge and m mass of the electron, and so on, provide for us a set of absolute units for measurement of distance, time, mass, etc. There are, however, more of these constants than are necessary for this purpose, with the result that certain dimensionless numbers can be constructed from them. The significance of these numbers has excited much interest in recent times, and Eddington has set up a… 
Running vacuum in the Universe and the time variation of the fundamental constants of Nature
We compute the time variation of the fundamental constants (such as the ratio of the proton mass to the electron mass, the strong coupling constant, the fine-structure constant and Newton’s constant)
Are the fundamental constants constant
Abstract This article reviews recent work on the possible variability of basic physical constants, such as the charge of the electron e, Planck's constant h and the gravitational constant G. The
Dirac's continuous creation cosmology and the temperature of the Earth
DIRAC1,2 has modified his earlier cosmological model based on the large number hypothesis3,4, that the observed approximate equalities are not accidental but causal—even though we are as yet unaware
Cosmological variability of fundamental physical constants
Gamow was one of the pioneers who studied the possible variability of fundamental physical constants. Some versions of modern Grand Unification theories do predict such variability. The paper is
Interpretation of the Dirac Relationship between Fundamental Constants
SINCE the original relationship pointed out by Dirac1,2, several dependent and independent numerological relations have been proposed. Dirac noticed that the ratio between the age of the Universe and
The fundamental constants and their variation: observational and theoretical status
This article describes the various experimental bounds on the variation of the fundamental constants of nature. After a discussion of the role of fundamental constants, their definition and link with

I argue that the laws of physics should be independent of one’s choice of units or measuring apparatus. This is the case if they are framed in terms of dimensionless numbers such as the fine
Artificial contradiction between cosmology and particle physics: the Λ problem
It is shown that the usual choice of units obtained by taking G=c=ℏ=1, giving the Planck’s units of mass, length and time, introduces an artificial contradiction between cosmology and particle
Crystal structures, the Earth and Dirac's Large Numbers Hypothesis
DIRAC'S Large Numbers Hypothesis assumes that the large, dimensionless numbers obtained from the ratios between fundamental physical constants are related to the age, t, of the Universe1–4. The
