This is THE book to learn real recursion theory from. It isn't as good a reference as Odefreddi (though soare has more on the r.e. degrees) but it actually explains what is happening and offers insight into the subject. This isn't a book for the non-mathematician who just wants to know what all this stuff about Turing machines is about. This is a full course that takes one from the beginnings of the subject to a point where you are ready to read (and produce) recent papers. I personally wish it had a little bit more on forcing constructions and other non-re constructions (this part is frustratingly short) but the book is more coherent and reasonably sized for their omission. The approach taken is more modern than that of Rogers and much preferable. Obscure rarely used notions (e.g., the Medvedev lattice) and repetition of the same material in different contexts is avoided in favor of going through more complex constructions and results in the r.e.-degrees.

This is a great introduction to poetry for those who haven't read a lot of it!
Far less romantic than you'd think it would be, "The Songlines" is an adventure in vulnerability and a surprisingly enticing invitation to accept humanity's ignorance of its own prehistory.
Reading this for the second time. As a baseball fan, I'm sad to say this book didn't register on my radar screen for a while, until my first employer out of college demanded I check it out. Thank goodness! It is, at its core, a book about exceeding the bounds of conventional thinking, and it discusses this with extreme thoroughness through the lenses of statistics and baseball mania. Reading this opened my eyes to a whole new way of watching an already much-loved sport, and reaffirmed my belief that the so-called baseball commentators on networks like Fox and ESPN are both blind and incapable of coherent speech. Scarily enough, after reading this the first time, my employer and I applied its core ideas to our own work and quickly became obsessed with our own 'Project Moneyball.' Sadly, as with the many baseball bigwigs and old-schoolers found in the pages of Lewis's book, we consistently found ourselves flinging bodies, words, and pages of data at a brick wall reinforced with concrete, steel beams, and a healthy dose of Mace. Alas, change is slow, and in any well-established industry, a true war of attrition.

Considering this book was written a year before the subprime collapse, the author pretty much nailed it...

I set the perpetual motion machine in motion again, it had stopped (something that never would have happened had Anna been there), and I was pleased to see the seascape light up and come to life within its aquarium--the fleecy waves, the shadows gliding along the shore--without any part of the system running on batteries or connected to an electric outlet of any kind. Rene Belletto's Coda is one of those novels that could frustrate with all its possible meanings, messages and puzzling pieces that somehow add up to a whole. The pieces of this story happen in a linear order, and seem logical as opposed to illogical, but then there is something askew about them, slightly off-balance. Somewhere during the novel, I began to feel Belletto's dreamy logic encompass me, make me feel as if I were seeing the events of the novel play out before in a blurry sequence. And like a dream, parts were so real even though I knew that they couldn't be. Reading Belletto is like lucid dreaming - the perfect intersection of fantasy and reality. The narrator is unnamed. The style is detached. The language is simple, almost plain. All of these elements, like any master of the surreal, serve as counter-agents to the reader's disbelief. The narrator, a father living in Paris with a young daughter Anna, has lost his wife. He is a well-off man who, heeding his father's deathbed request, brought to fruition his plan for a perpetual motion machine. With trial and error and much of his own ingenuity, the narrator succeeds and constructs a successful business selling the almost perpetual motion machines consisting of spiral and balls that has to be restarted once a day. This idea of the motion of time becomes the construction for the story and it's odd fragmented flow events that spring form the mundane. Beginning with a package of frozen clams, a mystery begins: I had to face facts: while I was away someone had some into my house and placed a package of Marty Frigor clams in my freezer. As ridiculous as this seems, it is presented so soberly, that reader doesn't hesitate to accept this, only perhaps wonder what it may signify in deeper terms. On the package is a name, Marc Kram, whom the narrator knows as an old school friend. After he contacts Marc and they reconnect, Marc invites him to a party. The narrator meets a woman, Marthe, who is beautiful but a friend to no one at the party and apparently only seen by narrator with whom she conversed. At this party, the narrator is also given the information of Marc's half-sister, Agathe, that once held the narrator's interest. When the narrator meets Marthe again, the reader is given enough information to think that there is an otherworldly quality to her, and one that is neither concretely good or evil. She delivers bits of conversation like this to our unsuspecting narrator: "You're theory is perfect. 'Death, fate's faithful servant...' Tired of being nothing but a spirit, I wanted to incarnate myself in the body of a mortal woman at the risk ... at the risk of meeting you," she said softly. As the events become stranger and more threatening - Anna is kidnapped and the narrator is led to believe it is the work of child traffickers - the pace, the motion of the plot powers along at a clipped tempo, never stopping for the consideration of the characters of the reader. A brilliant tactic by Belletto. The denouement is thrilling and it feels, like in life when something is that thrilling, that time sped up. And once the feeling fades, the questions that plague humanity's relationship with time arise: What does our time on earth mean, if anything? What does time that has gone by, the past, mean to each of us now? In the infinitum of existence, what does our life represent? Belletto himself can't help but chronicle the narrator's thoughts about existence and time: Where had all the dead, present and past, gone? Had they been lost to oblivion? Had they never existed? And how would people recount their history from now on, the histories of their families, their countries, or the history of the world? Of course Belletto can't answer these questions or many of the others that he raises, but it is difficult to not be enchanted by this book whether it is fantasy, mystery, noir or literary. Yet it is mesmerizing and believable as a dream had during a short afternoon nap that occupies our mind for the rest of the day. And like the titles points out, we wake again the next day to see how our life in motion will affect our dreams and vice-verse.

Not as utterly creepy as Heart-Shaped Box, but still enough to continue my fanhood of Joe Hill. Very inspired disgusting death scene of the "bad guy" in the end.

This was my first foray into Thomas Pynchon, despite suggestions to start elsewhere. And, admittedly, it was a bit of a hurdle. It's fairly straightforward for the first hundred pages or so, and then Slothrop drops his harmonica into the toilet and it all gets strange. The only advice I can give to anyone reading this book is not to stop. Most people I know who haven't read it have started the book several times over, and never made it too far. Dive into the deep end, and don't stop until the last punctuation mark. You will be confused. You will wonder what is going on. You will wonder who characters are, or why they belong in the plot. You will also have your heart broken in a few places, and you will laugh out loud. Pay attention. The book's got the word "Rainbow" in the title for a reason. And above all, enjoy Pynchon's unique train-of-thought prose.
