if you know what makes the thunder and the lightning, you can't watch a great storm without feeling very small and puny." "Of course not," Ken said. "Astronomers feel all that when they look a couple of billion light-years into space. Physicists know it when they discover a new particle of matter. But they don't go around muttering about omens and signs. You can feel the strength of natural forces without being scared to death.""Maybe that's what marks the only real difference between witches and scientists, after all! The first scientist was the guy who saw fire come down from the sky and decided that was the answer to some of his problems. The witch doctor was too scared of both the problem and the answer to believe the problem could ever have a solution. So he manufactured delusions to make himself and others think the problem would just quietly go away. There are a lot of witch doctors still operating and they're not all as easy to recognize as Granny Wicks!" They reached Ken's car, and he held the door open for Maria. As he climbed in his own side he said, "How about coming over to my place and having a look at the comet through my telescope? You'll see something really awe-inspiring then." "I'd love to. Right now?" "Sure." Ken started the car and swung away from the curb, keeping a careful eye on the road, watching for any others like Dad Martin. "Sometimes I think there will be a great many things I'll miss when we go back to Sweden," Maria said thoughtfully, as she settled back in the seat, enjoying the smooth, powerful ride of Ken's souped-up car. Ken shot a quick glance at her. He felt a sudden sense of loss, as if he had not realized before that their acquaintance was strictly temporary. "I guess a lot of people here will miss the Larsens, too," he said quietly. "What will you miss most of all?" "The bigness of everything," said Maria. "The hundreds and hundreds of miles of open country. The schoolboys with cars to cover the distance. At home, a grown man is fortunate to have one. Papa had a very hard time owning one." "Why don't you persuade him to stay here? Mayfield's a darn good place to live." "I've tried already, but he says that when a man is grown he has too many things to hold him to the place he's always known. He has promised, however, to let me come back if I want to, after I finish the university at home." "That would be nice."
