Dweeb? Jim, are you looking in a mirror while typing your posts?

Definitions of "scientific theory" on the Web:

* An explanation of why and how a specific natural phenomenon
occurs. A lot of hypotheses are based on theories. In turn, theories may
be redefined as new hypotheses are tested. Examples of theories:
Newton's Theory of Gravitation, Darwin's Theory of Evolution, Mendel's
theory of Inheritance, Einstein's Theory of Relativity.

* A hypothesis that is widely accepted by the scientific community.

* a statement that postulates ordered relationships among natural
phenomena.

* The most logical explanation of why things work the way they do.
A theory is a former hypothesis that has been tested with repeated
experiments and observations and found always to work.

* A body of knowledge using controlled-variable experimental
methods to construct a formal and mathematically structured system. It
studies the character of natural reality. Scientific Management (6).
System of management popular in the first decades of the 20th c.
Proponants sought to transform industry, government and society through
greater efficiency. Utilizes top-down approach.

* a theory that explains scientific observations; "scientific
theories must be falsifiable"

* The word theory has a number distinct meanings depending on the
context.

Jim, your point is excellent. Amateurs would be hard put to design an
efficient radiator array using known electrical laws as stated by
Maxwell. Imagine trying to design a yagi antenna using only Maxwells
observations
instead of the 'suck it and see' empirical methods used today. Known
electrical laws are simplicity in themselves usually just a paragragh
in length, could you supply the same for the Yagi? As I have stated
earlier the Yagi put antenna design back by over half a century since
it diverted thinking though around known electrical laws to taking the
easy empirical way out.
