Urbain Le Verrier on the Movement of Mercury - annotated translationsIn 1916, Einstein proposed three tests of general relativity, subsequently called the "classical tests" of general relativity: the perihelion precession of Mercury's orbit the deflection of light by the Sun the gravitational redshift of light.

In 1916, Einstein proposed three tests of general relativity, subsequently called the "classical tests" of general relativity:
¥ the perihelion precession of Mercury's orbit
¥ the deflection of light by the Sun
¥ the gravitational redshift of light.
The key evidence on which Einstein relied to support his theory was the first of these, which related to unexplained errors in the observations of Mercury's orbit reported in 1859 by Urbain Le Verrier, the Director of the Paris Observatory. As the available publications that led to Le VerrierÕs claim, which were developed over a period of nearly two decades, were complex and only available in French, as part of a larger project, I translated them into English and annotated them, to make them easier to understand. As it appeared that this might be helpful to other researchers, I decided to publish my translations in the current volume.

This book provides translations of two books, Le Verrier, U. -J. (1841), DŽveloppements sur Plusieurs Points de la ThŽorie des Perturbations des Plan�tes (Developments on several points of the Theory of Perturbations of Planets); and Le Verrier, U. -J. (1845), ThŽorie du mouvement de Mecure (The Theory of the Movement of Mercury); and a 195-page article, Le Verrier, U. -J. (1859), Theorie du Mouvement de Mercure (The Theory of the Movement of Mercury), Chapter XV in the Annales de LÕObservatoire ImpŽrial de Paris. It also includes a translation of the 1859 letter in which Le Verrier reported his claim, Lettre de M. Le Verrier ˆ M. Faye sur la thŽorie de Mercure et sur le mouvement du pŽrihŽlie de cette plan�te (Letter from M. Le Verrier to M. Faye on the theory of Mercury and on the perihelion movement of this planet), which was published in the Comptes rendus hebdomadaires des sŽances de l'AcadŽmie des Sciences (Paris).

The conclusions from this detailed review are that, rather than implying a systematic error in the calculated values, the steady reduction in the errors in the equations of condition could be seen to be a demonstration of a linear improvement in the accuracy of the measurements over time as one might expect, resulting in no adjustment to the elliptic elements, and no difference between the calculated rates of precession, and no support for EinsteinÕs theory of general relativity.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.
