stubby a true story of friendship купить по лучшей цене
THE CALCULUS OF FRIENDSHIP is the true story of an extraordinary connection between a teacher and a student-a thirty-year relationship based almost entirely on a shared love of calculus. For them, calculus is more than a branch of mathematics; it is a game they love playing together, a constant when all else is in flux. As the teacher goes from the prime of his career to retirement and loses a son, the student matures from high school math whiz to Ivy League professor, suffers the sudden death of a parent, and blunders into a marriage destined to fail. Through it all they take refuge in the haven of calculus-until a day comes when calculus is no longer enough.
