This memo talks about an emerging paradigm of computing using hyperbolas that are a result of the dynamic behaviour in systems consisting of a container (capacitor, bank account …) and a discrete event generator whose level of activity is modulated by the amount stored in the container (pressure, charge, amount of money…). It attempts to raise motivation for studying this phenomenon from some basic principles and analogues in real world (economy, physics, biology).
