I would like to get some opinions about interpreting Newton's laws of
motion.
I feel that all he meant was that if you want to move an object then you
must have a second object involved (to hit it or attract it).
Outside or external means "other than"

No. That was not all he meant.

He actually had something quantitative to say.

quantitative?[/quote:aacb417d26]
I see quantitative in the third law but not in the first or second.
Do see it in the first or second?

Implicit in the second law is a reference, and motion is always with
respect to something.

Newton's Second Law
http://scienceworld.wolfram.com/physics/NewtonsSecondLaw.html

Newton had is right, F = dp/dt is right on!

"The motion of a particle is described by Euler's statement of Newton's
second law, namely

F = ma

Here F is the applied force, m is the mass of the particle, and
a = dv/dt is the particle's acceleration, with v being the particle's
velocity. This equation, together with the principle that bodies act
symmetrically on one another--so that the force particle A feels from
particle B is equal to the force B feels from A--is the basis for
understanding particle dynamics".

"Newton's law completely describes all the phenomena of classical
mechanics...."

What would be new ,,is if you understood.
Atoms pussh them selves down energy slopes.

The gain in mass is F pushing te wieght of the atom.

Talk is cheap and you seem to be very generous. Pendulum test:

Hung your machine from a high ceiling and turn it on. Can it stay at a
45 deg angle with the vertical for an extended time without burning
fuel or producing lft using air foils or ionization wind?

You said "Newton's third law is also part of the problem. For ever
force there is an equal and opposite force."

That's not Newtons Third law exactly. The law is: For every action
there is an equal and opposite reaction...

Newton's law applies to a much broder spectrum of actions and reactions
than those produced by forces, i.e. contact or F =dp/dt. Did you say
you got no clue? Forget it. Try the pendulum test and feel the
embarishment that comes along with the denial of the laws of nature.
