• (6) ?v = iR

states one to current huge difference together a wire means current moments good lingering resistance. It’s got an equivalent analytical means since Poiseuilles laws (to possess most readily useful liquids):

• (7) ?p = V?k

and therefore says that the tension difference with each other a pipeline translates to new volumetric circulate price times a constant. These expertise shall be illustrated from the a common picture. While you are authoritative analogy is related in order to common analytical build, it should not be limited to nomic isomorphism (Bartha 2010: 209). The idea of specialized analogy generalizes in order to cases where you will find a common statistical build ranging from habits for two systems. Bartha also provides a more liberal meaning (2010: 195): “A couple features try formally similar if they consume corresponding ranking into the officially analogous ideas. Such as for instance, mountain throughout the concept of voice corresponds to color regarding theory of light.”

By contrast, thing example contains exactly what Hesse phone calls “observable” or “pre-theoretic” similarities. Similarities ranging from echoes (sound) and reflection (light), for example, was in fact approved a long time before we’d any detailed ideas on the these phenomena. I’ve each other point and you may official analogies between voice and you may light, and is also extreme to own Hesse the former are separate of one’s second.

You’ll find good reasons not to take on Hesses element thing analogy, construed inside thin means. Earliest, it’s visible you to specialized analogies certainly are the first rung on the ladder into the of several very important inferences. Lees verder →
