Conversation with myself
Newton's law of universal gravitation, first published in the Philosophiae Naturalis Principia Mathematica (1687) states that "every object in the Universe attracts every other object with a force directed along the line of centers of mass for the two objects that is proportional to the product of their masses and inversely proportional to the square of the separation between the two objects."Yeah, so?
So that flies in the face of logic, doesn't it? How can attraction be inversely proportional to the separation? That means that the further away something is, the weaker the attraction. But that's not the way it really works is it? What about "absence makes the heart grow fonder"?
Newton was talking about physics, not love.
Newton also wrote, in the first law of motion that "an object in motion, will remain in motion and an object at rest, will remain at rest, unless acted upon by an unbalanced force."
Oh, I get that you're imbalanced. Want to get to the point?
Newton's third law of motion states that "for every action there is an equal and opposite reaction."
*yawn* Fascinating.
I'm just saying that the heart at rest won't remain at rest when acted upon by the force of attraction. So even if (as you claim) Newton was right about attraction, the unbalance caused by the presence of a second heart sets the heart into motion which will not stop until an equal and opposite force brings the heart back to its original motionless state. Even if the second heart goes away, it takes an equal and opposite force to stop the motion induced by the attraction.
What about the second law, you conveniently skipped that.
Well, it doesn't really apply.
And wouldn't Newton have written all this in Latin? You don't read Latin.
Now you're just being difficult.

You crack me up. Are you coming over this weekend?
The inside of your head must be a facinating place...
Wait, I meant 'fascinating'...I really can spell, honest!
and you thought all this up AFTER I bombarded your brain with useless 2D gel nonsense???
When do you sleep, exactly?
and wasn't newton british? he might have written it in english. at least his first draft, anyway.
Bright-one: Probably. I need to be in the 'burb anyway so I can do the old "swing by".
KCTL: It gets me into more trouble than you'd imagine.
ESC: You mean, after I FIXED your project? But Newton wouldn't have titled his book in Latin only to write it in the vernacular, which in the 17th c. wouldn't remotely have had the vocabulary to describe physics and calculus anyway. :P
Fuzzball: Newton's second sexy law is often regarded as the the most important, the fundamental law of dynamics- The force applied to a body is the product of its mass and the acceleration induced.
geek.
