I was wondering what the duration of a dental X-ray is.
The reason I ask is that my dentist always takes the routine X-Rays
but failed to notice that one tooth was cracked and eventually fell
apart.Even he explained that it appeared to be an old crack.

Einstein was right: Unique stellar system provides 'laboratory' for testing
relativity
Pulsars are small, ultradense stellar objects left behind after massive
stars die and explode as supernovae. They typically have a mass greater than

From Osher Doctorow
A few years ago, Sir Michael Atiyah of the U.K., renowned discoverer
of K-theory and much else, wrote in the Bulletin of the American
Mathematical Society (AMS) more or less that one of the main problems

For polynomial functions the infinitesimal is a zero dimensional point
and derivatives are exact. For real world curves the infinitesimal is
two points infinitely close. We can only calculate an approximation of
the infinitely close therefore our answers for real world curves

Concept continued from recent prior posts:
... what then does the planet attractor act on if not on inertial
mass? The planet attractor acts on matter. At first thought, with
this conclusion, I appear to have returned to pre-Newtonian physics.

The curvature surounding the Earth will cancel the curvature from the
Sun. There then is no curvature for the Earth to orbit the Sun by. It
gets cancelled.

    The photon has been viewed as a somewhat mysterious entity which
sometimes has the properties of a particle and sometimes has the properties
oaf a wave. It would seem interesting to see, therefore, whether we can
