Very concise reply, as always. As indicated by my previous post I'm
in general agreement with you. "Inertia" is not a property at all,
just a sentiment. An incorrect one at that. A mass doesn't have
inertia, it has mass. A mass doesn't exhibit inertia, it exhibits
conservation of energy and momentum wrt other masses. Just one of many
meaningless concepts still present in modern texts.-

That point of view gives an unsatisfactory answer to:
"Where is the energy of a bullet stored?".

More troubling, It suggests we know all we need to know about
gravity and inertia and an eperiment like this that
localises the energy where it is hard to model and measure
is completly unwelcome if it challenges existing fromalism:

<< We report the first realization of a guided quasicontinuous
atom laser by rf outcoupling a Bose-Einstein condensate
from a hybrid optomagnetic trap into a horizontal atomic
waveguide. This configuration allows us to cancel the
acceleration due to gravity and keep the de Broglie
wavelength constant at 0.5 $\mu$m during 0.1 s
of propagation.

We also show that our configuration, equivalent to pigtailing
an optical fiber to a (photon) semiconductor laser, ensures
an intrinsically good transverse mode matching. >>
