“Strangely enough, there are signals that exist in all mathematical purity, such as on the one hand the sinus tones that have lasted for eternities and that will continue to sound for eternities, and on the other hand signals like the Dirac Impulse, whose large but finite energy discharges itself in an infinitely short time. Between these two extremes our life is made up, in the words of Sophocles, of ‘mere phantoms, shadows of nothing’.” - Friedrich Kittler - Lightning and Series - Event and Thunder
