‎Rare first edition of Sturm’s textbook on mathematics and geometry. Johann Christoph Sturm(1635 – 1703) was a German mathematician, astronomer who made significant contributions to mathematics and astronomy, particularly in the areas of geometry, trigonometry, and optics. He wrote several influential textbooks on mathematics and natural philosophy that were widely used in European universities during the 17th and 18th centuries. One of Sturm's most notable contributions to mathematics is the Sturm's theorem, which he developed in collaboration with his brother, Jacob Sturm. This theorem is used to count the number of roots of a polynomial equation within a given interval‎
