Ishihara Color Test

Famous quotes containing the words color and/or test:

    Since the quarrel
    Will bear no color for the thing he is,
    Fashion it thus: that what he is, augmented,
    Would run to these and these extremities.
    William Shakespeare (1564–1616)

    Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
    [sic] and to investigate other aspects of nature.
    Ian Hacking (b. 1936)
