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.

    Galileo Galilei was just such a man--a genius--and the first to turn the telescope to the skies to map the heavens. In doing so, he offered objective evidence that the earth was not the fixed center of the universe but that it and all the other planets revolved around the sun. Galileo kept careful notes and made beautiful drawings of all that he observed. Through his telescope he brought the starts down to earth for everyone to see.By changing the way people saw the galaxy, Galileo was also changing the way they saw themselves and their place in the universe. This was very exciting, but to some to some it was deeply disturbing. Galileo has upset the harmonious view of heaven and earth that had been accepted since ancient times. He had turned the world upside down.In this amazing new book, Peter Sís employs the artist's lens to give us an extraordinary view of the life of Galileo Galilei. Sís tells his story in language as simple as a fairy tale, in pictures as rich and tightly woven as a tapestry, and in Galileo's own words, written more than 350 years ago and still resonant with truth.
