About the Authors Robert Jansen, M.A. has taught AP Physics at Aliso Niguel High School in Aliso Viejo, California for more than 20 years, where he helped develop a large and competitive physics program that focuses on preparedness and confidence for students. He gravitated toward teaching physics because of the challenging material and a sustained belief that physics does not need to be mysterious and difficult, but rather can be comprehensible and achievable. Greg Young, M.S.Ed. has been teaching high school science for more than 20 years, and he currently teaches Honors Physics, AP Chemistry, and Chemistry at San Clemente High School in San Clemente, California.

Having always been interested in how to make science relevant to others, his interest in teaching lies in being able to create interactive lessons that engage students in their learning and form a relevant context for difficult concepts in physics. About the Publisher In the 1930s, Manuel H. Barron opened a bookstore in Brooklyn, New York. People from the community asked Mr. Barron about books that might be available to help their children study for the New York State Regents exams. After realizing there wasn't anything available, Mr. Barron created his own study guides. 80 years later, Barron's has helped millions of people prepare for their next step.
