Physical and mental descriptions use variables. Variables can be measurable and have units. Variables can be ratios with no units. Variables can be not measurable and have no values or units. Perhaps, brain is about measurable variables, but mind involves hidden immeasurable variables {hidden variable and sensations}. Properties that combine other properties can seem ineffable. For example, words can sound the same when used as nouns or verbs, but actually have subtle noun-marker or verb-marker sound features.
