Please don't try to tell me that "Krull" (SciFi) and something penned by David Brin, PhD, Astrophysics (Science Fiction) are comparable.<br /><br />The former is absurd entertainment full of made-up terms not verifiable or scientific in the extreme; the latter will have numerous scenarios based on extrapolation of actual science.<br /><br />Example: ever read Heinlein's "Starship Troopers," and then see the movie? Here's an example of the differences.<br /><br />In the book, the troops use powered fighting suits, delivered by a perfectly legitimate delivery method. They use real world tactics and extrapolations of weapons systems we already use, or are currently working on.<br /><br />In the movie, giant bugs shoot rayguns out of their butts, the troops are delivered in Conex containers, and run forward/flee in panic as a mob when in battle.<br /><br />In the book, Sergeant Zim makes a moral point that relates to tactics and stress under combat.<br /><br />In the movie, Sergeant Zim sticks a knife through a recruit's hand for the sheer hell of it. In the movie, he laughs - it's a big joke. In the real world, now buck Private Zim would be breaking rocks for 20 years for assaulting a troop for his own sadistic entertainment. <br /><br />Perhaps you might see a small difference between the two. <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis: </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>
