Snakes include some infrared in their reality, and honeybees include ultraviolet in their view of the world, and of course we build machines in the dashboards of our cars to pick up on signals in the radio frequency range, and we built machines in hospitals to pick up on the X-ray range.
Zmije vide dio infracrvenog spektra  u svojoj stvarnosti, a pčele uključuju ultraljubičasto u svoj pogled na svijet, i naravno, mi ugrađujemo uređaje u naše automobile koji primaju signale u rasponu radijske frekvencije, i izumili smo uređaje u bolnicama koji detektiraju raspon x-zraka.
