I assume someone kindly deleted this thoughtless response.

The link refers to a sensible thread among mathematicians
about the recent collision between satellites.
The point I was making was that most of the debris would collide with the earth,
since the collision was only 400 miles above the Earth's surface.

Dave, when I first opened your link, blank windows started popping-up so fast that I had to shut-down my computer. So, I thought the link was some type of joke.
Anyway, I discovered that the problem was on my end, so I deleted my post.

My apologizes.
 
Accepted.
Have you managed to read the link now?
I thought the subject was both topical and suited to this forum.

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
