Page 43 A rotating shell of matter induces Coriolis forces within it.
Page 60 The metaphysical element "absolute space" (from Newton) should be replaced by the totality of the cosmic masses (from Mach). i.e. by the fixed stars realizing a rigid reference system.
Page 61 Einstein said that relativity should be extended to arbitrarily roving reference systems and that gravitation should be described by the metric tensor of a curved spacetime.
Page 62 The space notion was part of classical mechanics.
Page 67 Mass and energy are the same according to the special theory of relativity.
Page 74 The metric g(uv) should be completely determined by the material distribution T(uv).
