Counting on Katherine: How Katherine Johnson Saved Apollo 13
Par Helaine Becker. 2018
You've likely heard of the historic Apollo 13 [mission]. But do you know about the mathematical genius who made sure…
that Apollo 13 returned safely home? As a child, Katherine Johnson loved to count. She counted the steps on the road, the number of dishes and spoons she washed in the kitchen sink, everything! 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 groundbreaking American woman who not only calculated the course of moon landings but, in turn, saved lives and made enormous contributions to history.

Par Elizabeth MacLeod. 2019
On April 19, 1907, a hundred thousand people lined up to watch the eighth running of the Boston Marathon. At…
the start of the race, more than one hundred runners surged forward, and at the end, Tom Longboat won it in an record-breaking 2 hours, twenty-four minutes, and twenty-four seconds. He became the most famous runner in the world, yet faced scrutiny and criticism of every part of his life, from his revolutionary training techniques to his Indigenous heritage. After the peak of his running career, Tom volunteered for military service in World War I. He survived, and faced further challenges upon his return. But Tom Longboat continued to live his life on his own terms, and his legacy as Canada's foremost distance runner continues to be recognized to this day.

Five Equations That Changed the World: The Power and Poetry of Mathematics
Par Michael Guillen. 1999
A Publishers Weekly best book of 1995! Dr. Michael Guillen, known to millions as the science editor of ABC's Good…
Morning America, tells the fascinating stories behind five mathematical equations. As a regular contributor to daytime's most popular morning news show and an instructor at Harvard University, Dr. Michael Guillen has earned the respect of millions as a clear and entertaining guide to the exhilarating world of science and mathematics. Now Dr. Guillen unravels the equations that have led to the inventions and events that characterize the modern world, one of which -- Albert Einstein's famous energy equation, E=mc2 -- enabled the creation of the nuclear bomb. Also revealed are the mathematical foundations for the moon landing, airplane travel, the electric generator -- and even life itself. Praised by Publishers Weekly as "a wholly accessible, beautifully written exploration of the potent mathematical imagination," and named a Best Nonfiction Book of 1995, the stories behind The Five Equations That Changed the World, as told by Dr. Guillen, are not only chronicles of science, but also gripping dramas of jealousy, fame, war, and discovery.Five Equations That Changed the World: The Power and Poetry of Mathematics
