|Analogy: formal parallelism. Intends show that from a similar case, similar conclusions can be drawn.|

Analogies/Physics/Electricity/Mechanics: Suppose we wanted to study the behavior of a complex system of several interrelated springs: then it is most practical to build a corresponding electric circuit to simulate the system. Instead of replacing the springs by strength, current and other levels can be regulated more easily. (>Analog computer, simulation).
Analogy/Aanalog/Theory/Principle of the Shortest Time/Fermat/Identity/Physics/Feynman: apparently, the statement of the shortest time and the statement that angles are equal in reflection, and that the sinuses of the angles are proportional at refraction, are the same.
