Defining the Fundamental Properties of Length, Time, and Mass<br />
From our interpretation of the electromagnetic units in terms of mechanical units we can<br />
now derive precise definitions of the fundamental mechanical properties (mass, length,<br />
time) that we can measure in terms of the constants of physics and geometry.<br />
Length: the Meter<br />
<strong>The</strong> meter be<strong>com</strong>es the value of the weber unit (Wb). Here is how the Wikipedia<br />
"Weber (Unit)" article introduces the weber, a unit of magnetic flux named for the<br />
German physicist Wilhelm Eduard Weber (1804–1891).<br />
"<strong>The</strong> weber may be defined in terms of Faraday's law, which relates a changing magnetic<br />
flux through a loop to the electric field around the loop. A change in flux of one weber<br />
per second will induce an electromotive force of one volt (produce an electric potential<br />
difference of one volt across two open-circuited terminals).<br />
Officially,<br />
Weber (unit of magnetic flux) — <strong>The</strong> weber is the magnetic flux which, linking a circuit<br />
of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero<br />
at a uniform rate in 1 second.<br />
In SI base units, the dimensions of the weber are (kg·m 2 )/(s 2·A). <strong>The</strong> weber is <strong>com</strong>monly<br />
expressed in terms of other derived units as the Tesla-square meter (T·m 2 ), volt-seconds<br />
(V·s), or joules per ampere (J/A).<br />
1 Wb = 1 V·s = 1 T·m 2 = 1 J/A = 10 8 Mx (maxwells)."<br />
What all this ballyhoo boils down to is that 1 Wb = 1 m, although they do not want to<br />
<strong>com</strong>e out and say so, and that makes the tesla its reciprocal. <strong>The</strong> meter is also then<br />
encoded into the definition of the ampere as the current in two long parallel wires of<br />
negligible cross section and d = 1 m apart in vacuum which gives rise to a magnetic force<br />
(Fμ) per unit length (l = 1 m) on each wire of 2 π ×10 -7 N/m. This result arises from<br />
Ampere's discovery of a force law:<br />
Fμ / l = μo I1I2 / 2 π d.<br />
(Here μo = 4 π ×10 -7 N/A 2 = 4 π ×10 -7 H/m.)<br />
<strong>The</strong>re is a question whether or not space is quantized. I think there is no way around it,<br />
because space has meaning only in terms of the matter that resides in it, and all matter is<br />
quantized into particles (protons and electrons), and there is a minimum distance allowed<br />
between an electron and a proton even though they want to join together and do so when<br />
conditions permit them to form into a neutron. This minimum distance is called the<br />
Bohr radius, named after Niels Bohr, the scientist who first calculated this natural<br />
displacement constant that appears to be due to inherent momentum in the electron --<br />
which may be due to the possibility that elementary charge itself has the nature of<br />
quantized momentum. We can express the Bohr radius (ao) as follows (where ħ is
