The History -- Timeline section includes a brief biography and a description of the work of each of these scientists. With the dynamic 3D animation, the development of our concept of the atomic structure is no more a static picture and text. These animation holds students' interest and stimulates thoughts of the scientific problem-solving learned from these ingenious experiments.
