Read full description

With this app students learn about the life and contributions to mathematics made by Leonhard Euler. It discusses his major mathematical discovers including his identity theorem which is considered to be one of his most significant accomplishements. Leonhard Euler is considered to be the greatest mathematician of the Eighteenth Century. He was born in Basel Switzerland, where he eventually completed a masters degree from the university there in just three years. Early in his life Leonhard Euler's parents wanted him to join the clergy. But young Leonhard was drawn to mathematics. Fortunately the great mathematician Johann Bernoulli recognized that Euler was a mathematical genius and agreed to tutor him. Health problems plagued Euler for most of his life. He eventually became blind but still continued to produce significant work in mathematics. Using this app students learn about his amazing life. It includes introductory information about mathematics. We hope that this app will inspire students to pursue careers in math. Students will enjoy using this graphically illustrated, interactive learning tool. The timeline feature presents key events in the life of Euler. Tapping on timeline points will bring up descriptions of historically significant events in the history of mathematics and the role that Euler played. A quiz function helps students demonstrate their comprehension of the reading material. Key concepts of both math and science are shown in colorful illustrations. We hope this app will inspire students to study math. The app shows that Leonhard Euler certainly deserves the place he has earned in the history of mathematics.
