The shelves of Dr. Dorina Kosztin’s office are full of colorful toys and apparatus, all demonstrating the power of science. As a physics professor, she is particularly fond of these toys because they show the practical, real-world dimensions of her field, well beyond the abstract equations and formulas typical of textbooks. Indeed, Dr. Kosztin has devoted her life to making physics a more accessible subject for students. Through her ongoing work, she has initiated major changes not only for programs in American institutions but in the very foundations of its classrooms.
