The fundamental unit of study of physics is the physical quantity.

Physical quantity is defined as a unit with a number.

This means that physics is the study of units.

Units makes physics consistent and this is the strength of physics. But scaling nature with absolute units poses a problem when it comes to studying fundamentals.

Fundamental rules of nature do not come with units. Nature is not unitful. Physics is.

Units are professional artifacts of physics.

What physicists call laws of physics or laws of nature are proportionalities without units.

In physics lingo a proportion is called a symmetry. Symmetry too is independent of units.

Newton worked with proportionalities not with units.

Before physicists started to split proportions into equations scientific research was done strictly with proportions.

The method of physics is to split a true proportionality into as many equations as needed and add to each equation units and constants and then name each equation with ideological and suggestive labels.

This practice designed to make physics a consistent system of units has many unfortunate side effects.

First of all, units and constants invented by physicists obscure the underlying rule.

It’s true that units are necessary at the fundamental level of measurement. Measurement means counting the unit in the observations.

But the choice of unit is irrelevant. There are no absolute and true units.

A rule (the symmetry or the law as physicists call it) such as the Kepler’s rule, is free of units.

Kepler’s rule ties the radius R and period T of an orbit as

The term R_{0}^{3}/T_{0}^{2} is the constant term. We can choose any unit as our constant and the rule will still work.

Physicists chose

This is fine. What is not fine is that physicists defined the conventional unit G as an absolute constant of nature.

I realize that astronomical constants have always been political properties.

In the 19th century British physicists defined G as a British unit to replace the “German” constant k^{2} that astronomers were using at the time as the value of R_{0}^{3}/T_{0}^{2}.

The British has been very successful in establishing G as a constant of nature. No physicist today remembers that G was a defined unit. But historical record leaves no doubt that G was a unit not a constant of nature.

The importance of the origin of G as a defined unit becomes clear when we observe that physicists claim to measure the experimental value of G in Cavendish type experiments.

Clearly, if G is a conventional unit it cannot be an experimental quantity. It makes no sense to measure the experimental value of say the inch, a conventional defined unit.

If G is not a measurable quantity how do physicists measure it?

They don’t. Physicists build their oscillators to give the correct value of G. Their experiment is circular. No pendulum was ever set in motion by Newton’s occult force and no physicist ever measured the experimental value of the political unit G.

I believe that physicists’ claim to measure the political unit G in physical experiments defines physics as the Newtonian cult. The sooner the physicists realize this the better.
