One girl, one sewing machine, one room.  Particle Zookeeper Julie Peasley is the sole seamstress, web designer, conceptualizer, mail packager, proofreader, driver, and emailer. Julie has had a lifelong interest in cosmology, the quantum world and theoretical physics. The particle plushies idea came about after attending a physics lecture at UCLA by Dr. Lawrence Krauss entitled "The Beginning and End of Time" in July 2007. A couple of difficult physics books later (including Lisa Randall's Warped Passages), Julie realized that the individual particles seemed to have various "personalities" that could be "felted out" with relative ease. After reading The Particle Odyssey by Chistine Sutton/Frank Close/Michael Marten and Gordon Kane's The Particle Garden, Julie’s adventure with particles began.
