The Rotini Model of an Atom

$\theta \left(t\right) = \theta_{0} +\omega t$

such that $\mathbf{A}$ is whirling about its polar axis with an angular frequency of $\omega$. The rotation supposedly blurs variations in the electric and magnetic radii leaving an effective orbital radius $R$ that is then used to represent the atom as a rotating cylinder. This rotating cylinder model smooths out some rough edges, but it is still incomplete because the electromagnetic part of the quark metric is larger than the other non-polar components. So one radial direction is predominant and the atom is shaped more like a piece of rotini pasta than a solid cylinder. This corkscrew spiral can be approximated by a geometric curve called a helicoid. It is described mathematically by radii of$\rho_{x} = R \cos{\! 2 \theta}$ | and | $\rho_{y} = R \sin{\! 2 \theta }$ | and | $\begin{align} \rho_{z} = \frac{ \lambda \theta}{2 \pi} \end{align}$ |
