- Albert Einstein. In this original work, Pritsker utilises his masterful ability to convey the excitement and elegance of mathematics to explore equations of all kinds, shapes, and sizes, while discussing their history, charm, and usefulness in solving problems from easy to extremely difficult. A rewarding work for both the recreational mathematician and the ambitious student.
