This volume provides annotated translations of the primary sources, which were largely in German, leading up to EinsteinÕs theory of general relativity, in which Einstein attempted to extend his theory of special relativity beyond space and time, to include matter and gravitational fields, by introducing gravity through his Òequivalence principleÓ - the equivalence of gravity and acceleration. This resulted in Einstein rejecting the second postulate of his theory of special relativity - the postulate on the constancy of the speed of light - in the presence of a gravitational field. This review reveals that EinsteinÕs theory of general relativity it is not a theory of gravity; it is a relativistic theory about the effects of gravitation, or more strictly, of a uniformly accelerated reference frame. There is nothing in any version of this theory that represents or explains or provides any connection to the weak attractive gravitational force between matter. In order to make calculations with his theory, Einstein had to import NewtonÕs empirical law of gravitation. Consequently, the only evidence that Einstein could provide for his theory of general relativity was effectively Newtonian.
Part I reviews NewtonÕs laws of motion and of gravitation, his definitions of inertial and gravitational mass, and his equivalence principle, which provide the background to EinsteinÕs theory. Part II provides a detailed analysis of the development of EinsteinÕs theory of general relativity. Part III provides a postscript on subsequent developments, and the Conclusion. In the light of the continued failure of EinsteinÕs efforts to overcome the main objections to his theory of special relativity - the Ehrenfest paradox, and its failure to explain the observed Doppler redshift and blueshift of light Ð or to provide any evidence for it, and in the absence of any supportive evidence for his theory of general relativity, both theories must be rejected until such objections are overcome and such evidence is provided.

Just lovely
Size: 8.5" x 5.8" x 1.9", Color: Orange
Purchased this several months ago and liked it, but I had received so many complements on this tray since then I had to submit this review. The tray is sturdy and put together well, and the size is exactly what was given before purchase.

These are a good choice
Color: Black-2 Set
These are great. They are made well, look nice and are easy to move when I’m dusting. I use these to keep perfumes, lotions and vitamins organized atop my dresser. The velvety compartments are a well sized and the layout is conducive to storing the kind of objects women or men typically store atop a dresser. I find these bins quite functional. I feel like these were a good value. They weren’t the cheapest and they weren’t the most expensive. They look nice and feel high quality enough.

Nice and works great in my nightstand
Color: Beige
Smaller than I expected, but good quality and looks nice in my nightstand drawer. It will keep things from rolling around. Seems sturdy and I like the pinkish undertone to the beige.

Great end table organizer, Style, size, cost
Color: Brown-2 Set
Good size, very useful tray. The large compartments are laid out well. Small areas good to hold a watch, change, lip balm, etc. Affordable price and made well, looks more expensive. Keeps "stuff" neat and clean.
