Transducers as Gates to the Universe.

The 'main structure and performances' of any physical system may be (nearly) maintained for a given time interval only if this system is kept inside a kind of 'shell' that protects it and only if the necessary (desired) exchange of energy-mass with its environment is realized through some transducers. The subsystem constituted by the shell and transducers constitutes a kind of 'barrier' between this physical system and its environment. Then, humans can exchange energy, mass, and information with their environment only though their available transducers. The paper presents sections about Plank energy, about inertia in rotation, translation, about waves and space dimensions, all based on classical physics and mathematics. These sections present in a different manner some very well-known physical phenomena. Associated with a new and convenient technology, all these models may be considered as innovation strategy importance. Applications may be found in interplanetary telecommunications and treks but also for everyday Earth vehicles and life. [ABSTRACT FROM AUTHOR]
