Description - Counting on Katherine: How Katherine Johnson Saved Apollo 13 by Helaine Becker
As a child, Katherine Johnson loved to count. She counted the steps on the road, the number of stars in the sky, the number of dishes and spoons she washed in the kitchen sink. Boundless, curious, and excited by calculations, young Katherine longed to know as much as she could about math, about the universe. From Katherine's early beginnings as a gifted student to her heroic accomplishments as a prominent mathematician at NASA, this is the story of a ground-breaking American icon who not only calculated the course of moon landings but, in turn, saved lives.
