table

n. a presentation of data in an ordered arrangement of overlaid vertical columns and horizontal rows. As with a graph, the purpose of a table is to communicate information (either in words or numerical values) in a concise, space-efficient manner that can be assessed at a glance and interpreted easily. The columns have headings; the leftmost column, which usually lists the independent variable, is referred to as the stub column. The intersection of a column and a row is called a cell. Tables are often accompanied by explanatory notes. —tabular adj.

Hering theory of color vision

Hering theory of color vision

a theory of color vision postulating that there are three sets of receptors, one of which is sensitive to white and black, another to red and green, and the third to yellow and blue. The breaking down (catabolism) of these substances is supposed to yield one member of these pairs (white, red, or yellow), while the building up (anabolism) of the same substances yields the other (black, green, or blue). Color blindness results from the absence of one or more of the chromatic processes. See opponent process theory of color vision. [proposed in 1875 by Ewald Hering]
