دانلود کتاب Slicing pizzas, racing turtles, and further adventures in applied mathematics

This challenging problem book by renowned US Olympiad coaches, mathematics teachers, and researchers develops a multitude of problem-solving skills needed to excel in mathematical contests and in mathematical research in number theory. Offering inspiration and intellectual delight, the problems throughout the book encourage students to express their ideas in writing to explain how they conceive problems, what conjectures they make, and what conclusions they reach. Applying specific techniques and strategies, readers will acquire a solid understanding of the fundamental concepts and ideas of number theory The author discloses the mathematics behind a host of problems, including gauging the length of the seam on a baseball, predicting the results of melting polar ice caps, and digging a hole to China. ch. 1.
