A forerunner of the Particle Adventure was a Supercard (TM) application developed by Andria Erzberger and her students, with physics assistance from Michael Barnett (LBNL) and Helen Quinn (SLAC), and technical assistance from James Quinn.

Carolyn Mockett produced the first version of the Particle Adventure in 1995. During the summer of 1996, Charles Groom completely revised the project. The newest version offers: expanded graphics, more animations, a decay path, historical information, search tools, increased organization, and new formatting.

We thank Ben Byers for redesigning the logo for the Standard Model Path used on the Particle Adventure Home Page.

Members of the Contemporary Physics Education Project have offered many suggestions and comments.

Throughout this entire process, members of the Particle Data Group at LBNL has offered invaluable support. In particular, we would like to thank Betty Armstrong and Gail Harper for proofreading and criticizing, and saying "I don't get it!" while poring over countless pages of material.

Some material was taken from the CPEP Classroom Activity Packet and from a soon-to-be-completed book by R.M. Barnett, H. Muehry, H.R. Quinn, G.J. Aubrecht, R.N. Cahn, J. Dorfan, M. Dresden, G. Goldhaber, J.D. Jackson, and K. Olive.

We are very pleased to thank the agencies, institutions, and corporations that have generously funded our efforts. These include the U.S. Department of Energy, the National Science Foundation, the American Physical Society's Division of Particles and Fields, Lawrence Berkeley National Laboratory, Stanford Linear Accelerator Center, Burle Electron Tubes, and the American Association of Physics Teachers.
