a humble grid pattern that conquered taxicabs, racing flags, and the floors of every diner ever
means A pattern of alternating squares in two colors, or one of the small round playing pieces used in the game of checkers, or a person or device that checks, verifies, or inspects something.
from From Old French 'eschequier,' the chessboard, itself from 'eschec' — the cry of 'check!' that ultimately traces back through Arabic and Persian 'shah,' the king. The squared board lent its name to anything gridded, so the cloth, the floor, the racing flag, and the cab all carry a faint echo of a medieval king cornered on his throne. The separate 'one who checks' sense grew straight from the verb 'check' once it meant to verify or hold in line.
