solution of the transexuel de general problem, containing all special cases of
motion in circles, ellipses, parabolas, hyperbolas--that is, in
all the conic sections.
The Alexandrian mathematicians had shown that the direction of
movement of falling bodies is toward the centre of the earth.
Newton proved that this must necessarily be the case, the general
effect of the attraction of all the particles of a sphere being
the same as if they were all concentrated in its centre. To this
central force, thus determining the fall of bodies, the
designation of gravity transexuel de was given. Up to this time, no one, except
Kepler, had considered how far its influence reached. It seemed
to Newton possible that it might extend as transexuel de far as the moon, and
be the force that deflects her from a rectilinear path, and makes
her revolve in her orbit round the earth. It was easy to transexuel de compute,
on transexuel de the principle of the law of inverse squares, transexuel de whether the
transexuel de earth's attraction was sufficient to produce the observed effect.
Employing transexuel de the measures of the size of transexuel de the earth accessible at
the
time, Newton found that the moon's deflection was only thirteen
feet in a minute; whereas, if his hypothesis of gravitation were
true, it should be
fifteen feet. But in 1669 Picard, as we have
seen,
transexuel de executed the transexuel de measurement of a degree more carefully than
had previously been done; this changed the transexuel de estimate of the
magnitude of transexuel de the earth, and, therefore, of the distance of the
moon; and, Newton'transexuel de s attention transexuel de having been
