The physical basis of natural units and truly fundamental constants

Abstract: Abstract. The natural unit system, in which the value of fundamental constants such as c andh are set equal to one and all quantities are expressed in terms of a single unit, is usually introduced as a calculational convenience. However, we demonstrate that this system of natural units has a physical justification as well. We discuss and review the natural units, including definitions for each of the seven base units in the International System of Units (SI) in terms of a single unit. We also review the fundam… Show more

“…This general symmetry framework based on flat space-time can accommodate (α) a unification of all interactions in nature and (β) all essential requirements for physics, such as conservation laws, quantizations of fields and physical frames of reference (inertial and non-inertial). [6,7,8] It was termed 'taiji 2 symmetry framework' [29] to stress its potential significance for all physics in any physical frame of reference.…”

“…Thus, the discrete analog (6) for equation 5is a nondimensionalized form of discrete analog (4) for equation 3. In other words, the solution to equation (3) can be obtained from the solution to (5), by converting it using the normalizing values (9). At the same time, equation (5) has a simple analytical solution: y = tg(x).…”

“…In the cited article, based on physical constants (light speed, gravitational constant, and minimal electrical charge), the author introduced the first natural system of units (L -length, T -time, and M -mass). All other authors, both in previous years and now [9], have used an identical approach in building their unit systems. A certain set of physical constants is selected and an independent unit system is built on their basis.…”

“…There is still an optional proportionality factor. But for the same reason that we did not refer to the speed of light, we also skip the proportionality factor , since it has no physical significance, but depends on the choice of units [88][89][90]: 36 For K 2 > 0 there are two different frequencies while for K 2 = 0 the eigenfrequencies are identical as in case of γ 0 . 37 Concerning the electro-magnetic duality rotation see for instance the short theoretical review article of J.A.…”
