I am cross posting this to alt.solar.thermal where all the big guns on

Correct Scientific Terminology:

Hypothesis - a guess as to why or how something occurs

Theory - a hypothesis that has been checked by enough experiments

to be generally assumed to be true.

Law - a hypothesis that has been checked by enough experiments

in enough different ways that it is assumed to be truer then a theory.

Note: nothing is proven in science, things are assumed to be true.

As I've told you before, a scientific "Law" is NOT a very thoroughly

established theory. It IS a theory that is essentially a mathematical

statement, such as Newton's Law of Gravitation (F=GMm/r^2), Snell's

Law of Refraction (sin(i)/sin(r)=u1/u2), and so on.

Here we go again...<grin>

Just because something can be proven mathematically

Does not necessarily make it reality...

The math is not needed...either for a theory...or a law...

what is needed is experiments....or observations....observations are the

result of natural experiments....usually the math comes after

the experiments have shown a hypothesis is possibly "real"....some

mathematics minded people do not accept this fact....they seem to feel

math is as good as an experiment....math can point someone in a

direction...but can not prove anything....just because you can show

something mathematically does not make it a theory....or a law....

For example...Mendals laws of genetics....do not think...even to this

day has been explained mathematically....

thank you for listening to my thoughts....again....have fun...sno

Math is the current best method used to describe the relationship between

observations.

I agree with your statement....but the question was, is the simple

definition of a law in science as below....or does it have to be proven

by mathematics.....and proof by mathematics makes it a law....not

experiments....

I realize that my definitions below are the simple form that were the

original when the scientific method was first conceived....and since

then they have been modified....and wiggle words included...<grin>

however if you can get by the modifications the original exists...

some people seem to think the original should be ignored...and more

modifications made to the present definition...both of theory and law...

thank you for your thoughts....have fun...sno
