Angles in the SI: treating the radian as an independent, unhidden unit does not require the redefinition of the term ‘frequency’ or the unit hertz

Some recent papers have argued that frequency should have the dimensions of angle/time, with the consequences that 1 Hz = 2π rad s−1 instead of 1 s−1, and also that ν = ω and h = ħ. This letter puts

On the dimension of angles and their units

We show the implications of angles having their own dimension, which facilitates a consistent use of units as is done for lengths, masses, and other physical quantities. We do this by examining the

Proposal for the dimensionally consistent treatment of angle and solid angle by the International System of Units (SI)

Because of continued confusion caused by the SI’s interpretation of angle and solid angle as dimensionless quantities (and the radian and steradian as dimensionless derived units), it is time for the

Outdoor Cultivation of the Microalga Chlorella vulgaris in a New Photobioreactor Configuration: The Effect of Ultraviolet and Visible Radiation

The application of CPCs to photobioreactors (PBRs) may be beneficial for microalgal culture in countries with higher latitude (with lower solar irradiance levels) and then decreased for higher ones due to the photoinhibition phenomenon.



On the units radian and cycle for the quantity plane angle

This paper is concerned with the names and symbols for quantities used to describe oscillatory motion such as for a harmonic oscillator, and the units to be used for the quantity plane angle and

Dimensionless units in the SI

The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider

On the Theory of quantum mechanics

The new mechanics of the atom introduced by Heisenberg may be based on the assumption that the variables that describe a dynamical system do not obey the commutative law of multiplication, but

A Treatise on Electricity and Magnetism

IN his deservedly celebrated treatise on “Sound,” the late Sir John Herschel felt himself justified in saying, “It is vain to conceal the melancholy truth. We are fast dropping behind. In Mathematics

Data and analysis for the CODATA 2017 special fundamental constants adjustment

The special least-squares adjustment of the values of the fundamental constants, carried out by the Committee on Data for Science and Technology (CODATA) in the summer of 2017, is described in
