Before modern day desktops and laptops, there were human computers or mathematicians who handled complex calculations. Katherine Johnson, Mary Jackson, and Dorothy Vaughan were among the greatest computers, but their vital work at NASA has been largely left out of history. This immersive book explores the lives and accomplishments of ingenious women mathematicians and coders throughout history, such as Johnson, Jackson, and Vaughan. Mini bio and feature boxes provide fast facts; while quotes from featured mathematicians, coders, and their contemporaries inspire readers to develop their own love for STEM. Original illustrations and stunning photographs bring the lives of these incredible women into exciting focus. A thorough timeline highlights the progress of women in STEM and lists Nobel Prize winners. A gallery spread introduces readers to even more women mathematicians and coders, while a Science Now spread shows readers the modern world of math and coding.
