No More Analogies
In my last post we developed the equations for the temperature of a powered resistor with or without an ambient environment.
As has been pointed out to me, and has now been made clear to me, is that “argument by analogy” is a trap. Analogies are an approximation to the “actual thing”, but are not the actual thing. Also, an analogy from an actual thing, to another idea-thing, doesn’t in any way indicate something else which is factually-actual.
What I mean is that a horse is analogous to a unicorn, however, this does not lend any support, not one iota of support, to the supposition that unicorns exist.
