<DIV>To Mr. Serret and the others:
<P style="MARGIN-BOTTOM: 0in">There is a nice example of the sort of sloppy
logic which I had recently referred to.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">When Kepler lived, he was brilliant in developing
his Laws.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">But a hundred years later, Newton had noticed some
minimal errors, specifically about the Gravitational equation, where Newton made
a correction where both masses need to be included in the calculation, which we
all use today.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">However, even Newton made a logical error there in
neglecting to apply his Fluxions / Calculus.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">In order for that Gravitational equation to be
more accurate, the Mass of the Sun needs to include all the collective masses in
the Solar System, and so he should have done a Summation to determine that mass,
which is clearly slightly greater than we generally realize. An interesting
detail is whether that mass of the Sun (for the gravitational equation) might
also need to include the mass of the Earth, where we would participate in both
factors of the Gravitation equation.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">However, our knowledge of the Gravitational
Constant is rather poor, only around three digits accuracy. Until some day in
the future when we know G more precisely, we simply tweak the value of G to
correct for the true total mass of the Sun in that equation.</P>
<P style="MARGIN-BOTTOM: 0in"><BR></P>
<P style="MARGIN-BOTTOM: 0in">My concern here is not so much in the math
involved, but more in being really careful in applying truly strict logic, to
enable Physics to grow and advance for the future.</P>
