<p>I thought a few weeks ago, that there might be a dimensional ladder for EM, but I can't figure out how turn into something usable. I'm sharing some of my markdown notes, now frustrated.<p>Starting from how an Ampere used to be defined (N/m, kg/s2)...<p>- V = Voltage, in Volts, (pre-2019 equal to m2/s)<p>- Q = Charge, in Coulombs, (pre-2019 equal to kg/s)<p>*Inertial Surfaces (J·s²)*<p><pre><code>  ∫V dt × ∫Q dt = m² × kg
</code></pre>
*Modes of Action (J·s)*<p><pre><code>  V × ∫Q dt = (m²/s) × kg

  ∫V dt × Q = m² × (kg/s)
</code></pre>
*Energy, Patterns of Stress (J)*<p><pre><code>  dV/dt × ∫Q dt = (m²/s²) × kg

  V × Q = (m²/s) × (kg/s)

  ∫V dt × dQ/dt = m² × (kg/s²)
</code></pre>
*Power, Waves of Stress (J/s)*<p><pre><code>  dV/dt × Q = (m²/s²) × (kg/s)

  V × dQ/dt = (m²/s) × (kg/s²)
</code></pre>
*Impulse, Wave Conversions (J/s²)*<p><pre><code>  dV/dt × dQ/dt = (m²/s²) × (kg/s²)
</code></pre>
*Spatial Derivatives, Effects on... 'Matter'?*<p>- d(Surface)/dx ~ Transport<p>- d(Action)/dx ~ Momentum<p>- d(Energy)/dx ~ Force<p>- d(Power)/dx ~ ??? Propagation?<p>- d(Impulse)/dx ~ ??? Conversion?<p>*Spatial Integrals, Effects on... 'Space'?*<p>- ∫(Surface)dx ~ Inertial Volume<p>- ∫(Action)dx ~ kgm3/s<p>- ∫(Energy)dx ~ kgm3/s2<p>- ∫(Power)dx ~ kgm3/s3<p>- ∫(Impulse)dx ~ kgm3/s4<p>In the wave modes for Power, 'Phase' =  dV/dt, Charge = Q, with Heaviside's wave equation
`d2(Volts)/dt2 + v2 * d2(Current)/dx2 = d2(Current)/dt2 + v2 * d2(Volts)/dx2`
would then....
`d2(Phase)/dt2 + u2 * d2(Charge)/dx2 = d2(Charge)/dt2 + u2 * d2(Phase)/dx2`
where v2 = 1 / LC, u2 = 1 / ??</p>

<p>re: Your Comments of Hegel elsewhere.<p>your name is reference to Stirner is it not? Hegel's realm of ideality is just that, a realm of ideality. Hegel's totality as well, a spiritual abstraction upon the world, but a good one to deny the Abrahamics and other mental rots of the west. The irony of totality is also, that it resolves back to the self, the process of becoming, the unique.<p>Dialectical analysis is a never ending, self-reflected, and interpenetrated spiral toward an asymptotic singularity.... but that is exactly what being is. Some X posited/constructed condition is always appearing, but X is not only X, the synthesized revelation of these arise in a new more real truth, along with a final truth that this process leads back, to some condition is always appearing.</p>
