Suggestions for improving the new proposal for base SI units revision. It’s well known that throw dimensional equitation can not discover hidden physical nature laws and gave as something new, because they are only as result of our human arbitrary conventions.

But if the units are chosen with wrong basic postulates than they can become main reason for stagnation or for developing of human knowledge.

The present International System of units SI is not finished job. It must be improved and developed in accordance with new theoretical research projects and also with new experimental equipments and techniques. There are seven principal SI base units in each of seven different categories. There was two special supplementary SI derived units units with special names. Because of their importance at first they are named as supplementary unitsbut later they are named as derived units.

Also there were preposition to make them base units. But now with new proposed special base units this dilemma shall be solved and they are only derived units and used only for angle calculations not for velocity and similar equations, connected with them. Draft Chapter 2 for SI Brochure, following redefinitions of the base units. Special base SI units.

Starting from well known concepts or facts for the basic phenomena and processes in nature as well as objects and objects that appear or contains in them, the following special units will be introduced and defined, which units will be starting mfrenja for basic or derived units definition, which are used in science and in society at all.

Distance – as space between two points. Radius – as element of the circle. Revolution – circle or any closed loop. Sphere – as ball surface. Globe – as merenjs at all. Cycle or Period mmerenja natural phenomena which repeat cyclic or periodical, with magnitude and time duration.

Particle or object – any particle or object which can be count, with same characteristic. Table with new Special base SI units. All special base units are very useful.

They are all variables and also tools, literally, for extending or shorting the metre. They are universal and independent units. These units connect spherical and flat spacemacro and micro cosmos and also curved and fractal space.

Dimension distance is any space as: Using them in dimensional analysis will show that many problems with formulas and equations can be solved. And the most important benefits from using this new set of special base SI units is that the problem of the rationalizations of the units also will be solved. Also the proposal for new unit with name object or particle par or obfor any objects as planets and stars or any known particles as photon, electron, proton, molecule and so on, is very useful.

When this unit is used in dimensional analysis than the unit name “object or particle” can be replaced with real name of the object or the particle. The second, s, is the unit of time; its magnitude is set by fixing the numerical value of the ground state hyperfine splitting frequency of the caesium atom, at rest and at a temperature of 0 K, to be equal to exactly 9 when it is expressed in the unit s -1which is equal to Hz. The next formula follow the definition for second, as base unit: The effect of this definition is that the second is the duration of 9 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium atom.

The problem with this proposal is that there is no formula connected with this definition? There are also next units by definition, using special base units, with base unit second. The metre, m, is the unit of length; its magnitude is set by fixing the numerical value of the speed of light in vacuum to be equal to exactly when it is expressed in the unit m s This proposal express with formulae. The problem with this definition is that the base unit for time, second, is determined by definition, equal to number of periods, not with formulae.

With this definition for second is hard to connect base unit metre with periods. Because of that it be usefully to take the definition for base unit second, as base, for definition of base unit metre. The metre, m, is unit of lenght; its magnitude is set by fixing the numerical value of the ground state hyperfine splitting frequency of the caesium atom, to be equal to product of number 3.

There are also next derived units, by definition, using special units, with base units metre. The kilogram, kg, is the unit of mass; its magnitude is set by fixing the numerical value of the Planck constant to be equal to exactly 6. If the equation for energy is express with special base units then next relations are valid. This equation can’t be base for base unit definition for mass, kilogram [kg]. Because the number of the electrons is taken as base to define the unit Coulomb, and with that the base unit Ampere, it be usefully to take also the number of the electrons as base, to define the basic unit kilogram.

The kilogram, m, unit of mass; its magnitude is set by fixing the numerical value of the number to be equal to product of number of 1. The product of kilogram [kg] and squared velocity v 2 by definition derived unit of energy – Joule [J].

The product of electron mass and number The ampere, A, is the unit of electric current; its magnitude is set by fixing the numerical value of the elementary charge to be equal to exactly 1. The present basic unit of electric current Ampere can’t be basic unit because is defined with Coulomb. Ampere is not unique unit, because depend of special units for velocity, and because of that also can’t be basic unit? The Coulomb, C, unit of elementary electric charge; its magnitude is set by fixing the numerical value of the number to be equal to product of number of 6.

The flow or flux of one Coulomb of electrons throw circle or closed loop, with circular velocity f o is namedby definition, derived unit for revolution electric current – Ampere revolution Ampere thread. The flow or flux of one Coulomb of electrons throw radius as part of the circle or closed loop, with angular velocity w is namedby definition, derived unit for radius electric current – Ampere radius.

The mole, mol, is the unit of amount of substance of a specified elementary entity, which may be an atom, molecule, ion, electron, any other particle or a specified group of such particles; its magnitude is set by fixing the numerical value of the Avogadro constant to be equal to exactly 6. The mole, mol, is the unit of amount of substance of a specified elementary entity, which may be an atom, molecule, ion, merena, any other particle or a specified group of such particles; its magnitude is set by fixing the numerical value of the Avogadro constant to be equal to number to be exactly 6.

Kelvin, unit of temperature – same as draft resolution 2, with special unit particle [par] and without [J]. The kelvin, K, is the elektrivna of thermodynamic temperature; its magnitude is set by fixing the numerical value of the Boltzmann constant to be equal to exactly 1. Implementation of this redefined SI units, in present International System of Units SIwill improve the system, clear the most of the existing problems in science and also gave new approach and solution for many physical laws.

These new proposed base SI units definitions will enable determination of all known rest derived ekektricna and constants. This set of derived units and constants must be part of this proposal for base SI units revision. Solving some of the most usual problems in Physics with new units: Length of distance, radius, circumference and cycle.

Linear relationship between redshift ,erenja distance. Hubble’s law is considered a fundamental relation between recessional velocity and distance. For distances R larger than the radius of the Hubble sphere rHS objects elektrivna at a rate faster than the speed of light??? If we express this equitation with new special SI base units we shall get: With this new proposal for special SI base units, for example, we can solve the existing problem with dimensions and units in well-known equation for the photon quantum energy, where are mix two units from different fields.

De Broglie has made such proposal with his wave theory, which claim that number of cycles in mwrenja path of the electron must elektricja integer.

This was made with formulas and descriptive method not whit units. Because of that De Broglie was enforced to make new proposal? There are many examples where such test can be made and many illogical results can be find. Some of units are independent from new special Si units as velocity and energy.

Because of that it was hard to see the existing problem with units. Fizikalne velicine i mjerne edinice SI – Dipl. Fizicke velicine i jedinic medjunarodnog sustava – Tomislav Cvitas, Nikola Kally, Hrvatsko kemisko drustvo, Skolska knjiga Zagreb, Elektricna merenja – V.

Jovanovic, Naucna knjiga Beograd, Wikipedia – the free Encyclopedia. Suggestions for improving the new proposal for base SI units revision Aco Z. Redefinition and improving the base SI units. Base for this SI units redefinition proposal are: Before any proposal for any unit redefinition, it be useful to make some suggestions for some postulates, as starting point.

Suggestion for basic postulates, for base or derived SI unit definition or redefinition. Unit Ampere depend on length and because of that can not be a base unit. It must be replaced with another unit.
