THE PRACTICE EFFECT description and bonus information


"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

"Aw, Denze, be fair . . . they're a little better'n cavemen. After all, they have learned that practice makes perfect...." -- The Practice Effect

In 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.

"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." -- No Wasted Ink 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." -- Amazon.com customer 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 Brin has taken a single premise (what if one of the laws of thermodynamics were repealed?), and woven it into a clever tale of a world of practical magic....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." -- blogcritics.org 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." -- Goodreads community review
