We see Math in children's games. We encounter Science in jokes. Every corner of life has been touched because of people like you that value a mathematical and scientific way of thinking. The RUBICON series of books was created to present electrifying ways to learn and never forget, by entwining entertainment with education in diverting stories.
Grade school students will be amused while being immersed in numbers, geometry, science, sports, critical thinking, and a dash of philosophy.
