I want to clear something up that you pointed out before concerning a magnetic force acting upon charges being equal and not opposite.
Describing the interaction of two identical charges traveling in perpendicular directions.The answer to the puzzle is this. Positive charges moves perpendicular to the magnetic force in one direction while negative charges move perpedicular to the magnetic field in the oppositwe direction.You can check it out here. http://hyperphysics.phy-astr.gsu.edu/...netic/forchg.html#c1 The electromagnetic for of q1 on q2 is equal but not opposite to the force of q2 on q1, in violation of Newton’s third law. In electrostatics and magnetostatics the third law holds, but in electrodynamics it does not. D. J. Griffiths Introduction to Electrodynamics 2cnd ed. p.321 In general Thus the force between moving electric charges does not obey the third law, because the force propagates with the velocity of light. S. T. Thorton Classical Dynamics of Particles and Systems 3rd ed. p.45 You also seem to think that science knows why inertia works in the tendency of an object in motion or at rest to remain so. Science has no idea why.Newton merely states what is observed in nature.That we can calculate the effects of a force acting upon an object according to Newtons laws is the evidence that favours the use of its methods.
I apologize if I gave this impression. I believe science only describes and predicts behavior. I don’t believe it explains why.
When I used the example of Galileos experiment I was trying to show that if you think about real inclined planes done the way Galileo did it then the obvious result is not that the ball continues on forever but that something is impeding it in order for it to stop which is the observation made.Doubtless he[Newton] was aware of the friction and gravity that made the ball eventually stop.But to generalize it to the point where free of forces the ball would follow the first law is a stroke of genius and behold our generations in space confirming that such events do occur.
I completely agree with you.

Thus the force between moving electric charges does not obey the third law, because the force propagates with the velocity of light. Doesn't gravity also propagate at the speed of light? So basically Newton's laws are wrong?

In electrostatics and magnetostatics the third law holds, but in electrodynamics it does not. I do not have a copy of the book by Mr Griffiths so could you explain what direction the equal reaction takes between q1 and q2? Thank you.

There is a new thread Newtons Laws for this discussion. It has nothing to do with "What is a Creationist?" Thanks.
What goes? The Nose Knows!

This probably sounds like an aquard question but i could not get any anwser when i looked it up on yahoo search... So my question is what are creos?

Creo is just shorthand that some use around here for creationist. You'll see that some also use the shorthand "evo" for evolutionist (although I'm not sure that is even a word that means anything... Can I be a gravityist?). Creo is not to be confused with the creoles you will find in new orleans

people seem to forget what iq means.
it's a rating of potential energy. people of high iqs can learn faster and more. CAN. not DO. honestly i think iq is more likely to reflect a different wiring in the brain rather than a better wiring. but then the only smart people i know are also odd. but no. the intelligence and argumentation a person may possess should not have any bearing on their believeability. master debater =/= right.

Anyone who believes that the universe was created by an outside "Creator". They can be of any religion, or even thing that the "Creator" was some no GOD critter.
Most often it is used to describe Christian Biblical Creationists, but even there it cannot be specific unless qualified. Most Christian Creationists also accept the Old Universe and Earth and Evolution. Others accept the Old Univese and Earth but think man a recent special creation. Then there are those that accept only the Young Earth position. Aslan is not a Tame Lion
