  <default_description>Bernhard Riemann was an underdog of sorts, a malnourished son of a  parson who grew up to be the author of one of mathematics' greatest  problems. In &lt;I&gt;Prime Obsession&lt;/I&gt;, John Derbyshire deals brilliantly  with both Riemann's life and that problem:  proof of the conjecture,  &quot;All non-trivial zeros of the zeta function have real part one-half.&quot;  Though the statement itself passes as nonsense to anyone but a  mathematician, Derbyshire walks readers through the decades of reasoning  that led to the Riemann Hypothesis in such a way as to clear it up  perfectly. Riemann himself never proved the statement, and it remains  unsolved to this day. &lt;I&gt;Prime Obsession&lt;/I&gt; offers alternating chapters  of step-by-step math and a history of 19th-century European intellectual  life, letting readers take a breather between chunks of well-written  information. Derbyshire's style is accessible but not dumbed-down,  thorough but not heavy-handed. This is among the best popular treatments  of an obscure mathematical idea, inviting readers to explore the theory  without insisting on page after page of formulae. &lt;/p&gt; In 2000, the Clay Mathematics Institute offered a one-million-dollar  prize to anyone who could prove the Riemann Hypothesis, but luminaries  like David Hilbert, G.H. Hardy, Alan Turing, Andr&#233; Weil, and Freeman  Dyson have all tried before. Will the Riemann Hypothesis ever be proved?  &quot;One day we shall know,&quot; writes Derbyshire, and he makes the effort seem  very worthwhile. &lt;I&gt;--Therese Littleton&lt;/I&gt;</default_description>

    <body><![CDATA[This book describes the Riemann Hypothesis, which is the most famous unsolved problem in Mathematics.  It is accessible to non-mathematicians.  The author divides the chapers up into those that require some math knowledge (the odd numbered chapters) and those that are historical (the even numbered c...<a href="http://www.goodreads.com/review/show/14359163">more...</a>]]></body>

    <body><![CDATA[Just plain amazing.  As an introduction to a difficult subject, as a biographical work, as a just plain entertaining read, this book scores right off the charts.<br/><br/>There IS some damn tricky math in here...that's the whole point, so I certainly wouldn't try to pitch it to the type of person ...<a href="http://www.goodreads.com/review/show/30183054">more...</a>]]></body>

    <body><![CDATA[One of the best math/science/history books I've read. The math chapters should be accessible to anyone. The early ones were a bit distracting to me since it was all &quot;old math&quot; to me but that means it should be accessible to anyone who'll give the math a chance.<br/><br/>Many surprises an...<a href="http://www.goodreads.com/review/show/12427495">more...</a>]]></body>

    <body><![CDATA[Reimann's function is fascinating !  But I still don't get it.<br/><br/>As the author says (pg 89):<br/>&quot;The difficulty people have in grasping these ideas is a reminder that mathematical thinking is, at some level, deeply unnatural.&quot;<br/><br/>Or, as I always say, &quot;We are not tru...<a href="http://www.goodreads.com/review/show/3110032">more...</a>]]></body>

    <body><![CDATA[Derbyshire delivered as promised, and explained the prime number theorem and the Riemann hypothesis with very little calculus, so the three star rating probably isn't fair, because this was a well written, entertaining book. But it's also a very tedious book that requires the readers full attention....<a href="http://www.goodreads.com/review/show/48665478">more...</a>]]></body>
