Twisters were not living things. Twisters had no will or volition, they felt no joy or pain. Truly, really, genuinely, tornadoes were just big storms. Just atmospheric vortices, natural organizations of rapidly moving air that blindly obeyed the laws of physics. Some of those laws were odd and complex and nonlinear, so their behavior was sometimes volatile, but twisters were not magic or mystical, they obeyed laws of nature, and Jerry understood those laws. He had patiently demonstrated their workings to her, in hours and hours of computer simulation. Jane knew all that with complete intellectual certainty.
