William Straub, Ph.D.
Dr. Straub will discuss joint kinematics (i.e., actions, sequence of joint actions, planes, and axes of rotation).

Bill Straub, Ph.D., FACSM, is Coordinator of Conferences and Research for the International Sports Training Institute at Life University in Marietta, Georgia. He also teaches an online sport psychology course for Syracuse University. In 1992, after 24 years, he retired from Ithaca College in Ithaca, New York, where he was Professor of Exercise and Sport Science.

While at Ithaca, Straub taught sport psychology, kinesiology, and biomechanics of human movement. He also coordinated the graduate program for seven years and was President of the All-College Faculty Council. A former professional baseball player, Dr. Straub coached high school sports for 14 years and was Associate Dean of the School of Health Physical Education and Recreation (HPER) at State University of New York at Cortland.

Professor of Physics

Clint Sprott, Ph.D.
Professor Sprott will discuss contact, control, and friction between the hand and ball. He will also speak about backspin and its relationship to angle of incidence and angle of reflection.

Professor Sprott received his B.S. from the Massachusetts Institute of Technology in 1964 and his Ph.D. from the University of Wisconsin in 1969. Most of his professional career has been devoted to experimental plasma physics with an application to the development of controlled nuclear fusion. This interest began in graduate school, where he studied electron cyclotron resonance heating of plasmas, and continued with his subsequent employment at the Oak Ridge National Laboratory, where he worked on an electron cyclotron heated mirror device and the design of its toroidal successor. Upon returning to the University of Wisconsin, he continued and expanded these studies to include ion cyclotron resonance heating in octupole and tokamak devices.

Since 1989, his work has been mostly in nonlinear dynamics and chaos. He developed several commercially available computer programs that demonstrate chaos and perform time-series analysis of experimental data with the aim of clarifying the underlying dynamics. In 1984, he began a program called The Wonders of Physics, aimed at generating interest in science and encouraging students to consider scientific careers.

This effort has included: over 200 public presentations to a total audience of about 30,000; teacher workshops; development of educational software, videotapes, and a lecture kit; and the training and supervising of graduate students and teachers in employing these techniques.

Professor Sprott is author of three books and over 200 technical papers and abstracts. He is a fellow of the American Physical Society, winner of the first annual Computer in Physics software contest (1990), and winner of the John Glover Award at Dickinson College in 1994.

Sports Medicine Expert

Dr. Mark Timmerman
Since the beginning of HMO's in the 1980's, it has been increasingly difficult for Coach Terry Roach, both as a coach and athletic trainer, to get injured athletes to the best sports medicine specialist associated with each of the three HMO's in Madison. To know who is best at each HMO was kind of like, trial and error with athletes injuries. Within only a few experiences of sending injured players to Dr. Mark Timmerman, injured players were returning to Coach Roach with an accurate diagnosis, a rehabilitation plan and an accurate a safe estimated time of return to the court. Because of the many years that have since followed, Coach Roach asked Dr. Timmerman to join the Shot Perfect staff of “Experts”. As our sports medicine expert, Dr. Timmerman will be featured as part of a special segment, immediately following “Shooting for Perfection from the Line”, of care and management of athletic injuries. While highlighting Dr. Timmerman's expertise in this segment, we hope to include different modalities offered by Mueller Sports Medicine.
