Title: superbly written Review: I highly recommend this book to anyone interested in spinor calculus. The authors' primary goal is to investigate the problem of defining Lie and covariant differentiation of spinor fields. This they do, but in addition, they carefully cover a number of standard topics and a number that I'd not seen elsewhere (such as the decomposition of a connection into constituents including the contorsion & metric-incompatibility tensors) in an extremely lucid way.

Title: Raquel rocks! Review: With very little 'dialogue' this film is still interesting, and a little scary. The adventure of a dark-haired caveman who stumbles upon a tribe of blonde-headed cavemen and cavewomen may not sound too interesting but Raquel is hot in her fur bikini!This is not hokey.The plot was copied mercilessly by the film "Caveman" which plays for laughs rather than this more creepy film.

Title: An Uncommon Woman Review: I enjoyed this book immensely. I am annoyed that the press focused so completely on so few lines. Hillary is a lot more than an aggrieved wife. Her decision to stay with Bill was consistant with her commitment to her values, even when times are tough. She has accomplished a great deal in the public arena in her own right. She is also an excellent writer and carries the reader along what was a very bumpy road, with humor and humility. People have assumed that she wants to be president some day, even though she knows how grueling and thankless the job can be. I sincerely hope so!

Title: Buy Abba's Greatest Hits instead! Review: Acting (if you could call it acting!) horrible, the singing shrill and does not in the least compare to Abba, the screen play ridiculous.I can't understand serious actors like Meryl Streep and Colin Firth even accepting this disaster screenplay - what a MESS all around - simply ridiculous.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
