WikiMechanics begins with the premise that we can understand ordinary space by describing sensation. And, we also need some room to build quark models. So let’s start by defining an algebraic vector space made from the radius vectors for some finite collection of particles . This mathematical construction is generically written as

Radius vectors are defined by describing sense perceptions, so ultimately is defined by sensation too. We say is three-dimensional because the three components of a radius vector represent three distinct classes of sensation which may change independently of each other. These three components are not the Cartesian coordinates that we usually use in geometry because instead of being associated with lengths, they are defined by counting quarks. Moreover, this space is explicitly constructed to keep track of quarks, so is called a **quark space**.

The following basis vectors are used to make general descriptions; the **magnetic axis** is defined by the **electric axis** from and the **polar axis** by . Then, any radius vector in can be expressed in terms of its components as The norm of a radius vector in quark space is given by

Quark Metric | ||
---|---|---|

centripetal component | 1 | |

electric component | -0.0152286648 | |

magnetic component | +0.7453740340 | |

electromagnetic component | -0.9292374609 | |

electroweak component | +1.5428187522 | |

magnetoweak component | -1.2742065050 |

This function compresses all three components of a radius vector into a single quantity that depends on the six numbers shown in the accompanying table. These constants are known collectively as the quark metric.

Particles and anti-particles have symmetrically opposed radius vectors, . So their norms are the same as each other

Quark space is a poor approximation to ordinary space, it is coarse and grainy because quark coefficients are always integers. And is squashed in a funny way because metric components are not Euclidean. But these messy details are handled mathematically, and in the following articles we make idealized quark models using conventional graphics. Next we consider the work that is required to build a quark model.
