Our visual perception depends on the reception of
energy reflecting or radiating from that which we wish
to perceive. If our eyes could receive and measure
infinitely delicate sense-data, we could perceive the
world with infinite precision. The natural limits of our
eyes have, of course, been extended by mechanical
instruments; telescopes and microscopes, for example,
expand our capabilities greatly. There is, however, an
ultimate limit beyond which no instrument can take us;
this limit is imposed by our inability to receive sense-
data smaller than those conveyed by an individual
quantum of energy.
