THE PRACTICE EFFECT

by DAVID BRIN

now revised, and with a new introduction by the author

Pop anthropologists claim, oh, happy refrain,
That
man's defined by tools.
Tools help us abide
ol'entropy's tide,
But even
they obey the rules!
The Practice Effect

does practice make perfect?

"He tried to remember a few facts from the linguistics course he had taken in college in order to get out of the infamous Professor LaBelle's English 7. There were a few sounds, he had learned, that were nearly universal in meaning among human beings. Anthropologists used to use them at the beginning of contact with newly discovered tribes. He swallowed, then ventured one of them. 'Huh?' he said." — The Practice Effect

Physicist Dennis Nuel was the first human to probe the strange realms called anomaly worlds — alternate universes where the laws of science were unpredictably changed.

But the world Dennis discovered seemed almost like our own — with one perplexing difference. To his astonishment, he was hailed as a wizard and found himself fighting beside a beautiful woman with strange powers against a mysterious warlord as he struggles to solve the riddle of this baffling world.

    The Practice Effect reviews

    Publishers Weekly

    "Reminiscent of the freewheeling, high-spirited alternate world novels of the '40s ... Lively, outlandish and entertaining."

    blogcritics.org review

    "David Brin's The Practice Effect is the reason I began reading everything I could find by this author. Brin has taken a single premise (what if one of the laws of thermodynamics were repealed?), and woven it into a clever tale of a world of practical magic.... Further, the central concept of the novel makes explicit the crucial difference between creators and users."

    Isaac Asimov's Science Fiction Magazine

    "High spirits and inventiveness ... Dennis's adventures, which can only be called rollicking, are legion."

    Goodreads community review

    "It started off feeling a lot like John Carter from A Princess of Mars meets A Connecticut Yankee in King Arthur's Court. By the end I added a good dose of the movie Speed to the mix. That pretty much sums it up. Except for one thing that made it exceptional — the practice effect. I love when an author comes up with a really original idea that would deeply influence how things turned out in the world and follows it through. It turned a really basic and frequently used idea, that of the modern man or scientist who finds himself in a society that has little or no technology, and turned it into something interesting."

    No Wasted Ink review

    "This is a clear forerunner to his development of science to propel the plot in his later novels. The concept of the practice effect itself makes this novel one that you should take a look at in addition to Brin's other more well known works. To me it was as if the world was a character all unto itself. I kept wanting to see more of how the practice effect changed the lives of these people. Although I read this novel many years ago, I have never forgotten it and I feel it is a work that needs to be called attention to. Otherwise, you might miss out on a truly unique science fiction experience."

    Amazon.com customer review

    "Gee, not every SF book has to be a deep exploration of the limits of the genre. Sometimes you just like to kick back and enjoy yourself. This is exactly what this book is, and it's a great read, fast and fun at the same time, while still throwing up some interesting concepts."

    Poul Anderson

    "A delightful, often very witty story, with the underlying thoughtfulness we expect from David Brin."

    testimonials

    reviews and recommendations

    Vernor Vinge

    "More than any writer I know, David Brin can take scary, important problems and turn them sideways, revealing wonderful opportunities. This talent shows strongly in Kiln People, a novel which is deep and insightful and often hilarious, all at the same time."

    praise for Heart of the Comet

    "A magnificent effort ... their story gets better, and better, and better."
    — Locus

    praise for Earth

    "Brin is a physicist of note who has been a NASA consultant, and he knows how to turn the abstractions of particle physics into high adventure.... He excels at the essential craft of the page-turner, which is to devise an elegantly knotted plot that yields a richly variegated succession of high-impact adventures undergone by an array of believably heroic characters."
    — Thomas M. Disch, EW.com

    praise for Sundiver

    "The original Progenitors have long disappeared, and the intergalactic search for relics of their presence, along with the conflicts generated by humanity's asserted uniqueness, shapes much of the sequence, which Brin enlivens throughout with exceedingly clever depictions of a wide range of Alien species."
    — John Clute, The Encyclopedia of Science Fiction
