Title: elegant observations
Review: The best aspect of this book is how it explains to an educated reader, who is not an astronomer or physicist, the latest results that confirm Einstein's theories. It is still not a light breezy read. While non-mathematical, you do still need to pay attention to the various concepts as Keel explains them.Some of the observations are very elegant, like gravitational microlensing. And the analysis of the vast data accumulated from IRAS, Hubble and Chandra. What is impressive is how lensing is now no longer used as a test of General Relativity, but as an extremely powerful "telescope" in its own right.
