"This is in praise of Sabrina, Extremely high ranking IMSA student, airplane builder and deserving of many paragraphs of praise. Sabrina quickly understood the educational value of starting the learning of science with Conceptual physics rather than the conventional ninth grade biology... long on latin, polysyllabic terms and without any sense of how a scientific discipline works. We now have over 2000 public high schools that have adopted the more coherent and sensible sequence: P-C-B with extraordinary positive results." Leon Lederman
