Question

why was math so important to Esther?​

Answer 1

Answer:

Esther Seiden (Hebrew: אסתר זיידן; March 9, 1908 – June 3, 2014) was a mathematical statistician known for her research on the design of experiments and combinatorial design theory.[1] In the study of finite geometry, she introduced the concept of the complement of an oval,[2] and her work with Rita Zemach on orthogonal arrays of strength four was described as "the first significant progress" on the subject.[3]
