$\mathbb{Q} = \left\{ \overline{\rho}^{ 1 }, \ \overline{\rho}^{2}, \ \overline{\rho}^{3} \ldots \ \overline{\rho}^{\, i} \ldots \ \overline{\rho}^{\, N} \right\}$

Radius vectors are defined by describing sense perceptions, so ultimately $\mathbb{Q}$ is defined by sensation too. We say $\mathbb{Q}$ 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 $\mathbb{Q}$ is called a**quark space**. The following basis vectors are used to make general descriptions; the

**magnetic axis**is defined by $\hat{m} \equiv (1, 0, 0)$, the

**electric axis**from $\hat{e} \equiv (0, 1, 0)$ and the

**polar axis**by $\hat{z} \equiv (0, 0, 1)$. Then, any radius vector in $\mathbb{Q}$ can be expressed in terms of its components as

$\overline{\rho} = \rho_{m} \hat{m} + \rho_{e} \hat{e} + \rho_{ z} \hat{z}$

The norm of a radius vector is

$\left\| \, \overline{\rho} \, \right\| \equiv \sqrt{ \vphantom{\sum^{2} } \; \left| \; k_{mm} \rho_{m}^{2} + k_{ee} \rho_{e}^{2} + k_{zz} \rho_{z}^{2} + 2 k_{em} \rho_{m} \rho_{e} + 2k_{mz}\rho_{m} \rho_{z} + 2 k_{ez}\rho_{e} \rho_{z} \; \right| \; }$

This function compresses all three components of a radius vector into a single quantity that depends on six numbers known collectively as the quark metric. Theorem: Particles and anti-particles have symmetrically opposed radius vectors $\overline{\rho} \left( \sf{P} \right) = - \overline{\rho} ( \sf{\overline{P}} )$ so their norms are the same

$\left\| \, \overline{\rho} \left( \sf{P} \right) \, \vphantom{\left( \sf{\overline{P}} \right)} \right\| = \left\| \, \overline{\rho} \left( \sf{\overline{P}} \right) \, \right\|$

Quark space is a poor approximation to ordinary space, it is coarse and grainy because quark coefficients are always integers. And $\mathbb{Q}$ 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 and freely available software.
