Experiences gained through teaching this course ultimately led to several students and friends encouraging me to pursue this writing project. Much of the content for Science in the Arena originated from students asking insightful questions and presenting new material in class. viii Acknowledgements I would like to thank my colleagues in the Physics Department at William Jewell Collegeforvaluableconversationsandencouragement.Inaddition,Iamgratefulto all my students, who have motivated me with their perceptive questions and stimulating classroom discussions. Finally, I would like to extend my deepest appreciation to my family and friends for their love and support. ix
