Herr Schrödinger demonstrated by means of calculation that under a suitable
choice of the coordinate system the energy components of the gravitational
field of a sphere vanish (outside of
Understandably, Herr Schrödinger is sur-
prised by this result and I too found it rather quaint at the beginning. In particular,
he asks himself if the are really to be interpreted as the energy components. To
Herr Schrödinger’s scruples I would like to add two more:
1. While the energy components of matter form a tensor, this is not the
case for the quantities that are called the “energy components” of the
2. The quantities are symmetric in their indices and ,
but the analogous are not.
H. A. Lorentz and Levi-Civita have misgivings about accepting the as the
energy components of gravitation because of the reason listed first.
While I understand their scruples, I am still convinced that a more useful
determination of the energy components of the gravitational field—other than the
one I have chosen—is not possible. I already gave the most convincing formal rea-

Herr G. Nordström already notified me a few months ago of the vanishing of the com-
ponents for this case.
