An Experiment: Experience the principle of oscillation!
Trogemann & Scherffig
On waiting during computation – synchronization strategies in parallel and interactive systems:
From this general perspective, the synchronization problem in computer science is inherent in the system, i.e., without being explicitly intended, the need to synchronize computing processes follows from the nature of computing itself and is thus deeply and inseparably inscribed in the central concept of the algorithm.
