Do you love solving problems with mathematics? So did groundbreaking computer programmer Jean Bartik. She turned her passion for math into a successful career in what was then a brand-new field. During World War II, women took on more technology jobs as men joined the armed forces. Bartik started her career doing mathematical calculations for top-secret weapons systems projects. After the war, a new machine took over these calculations. It was the first all-electronic computer, and Bartik helped build and program it. But how did Bartik's interest in mathematics take her to the forefront of cutting-edge technology? Find out how she went from gifted student to software pioneer.

Have you ever taken something apart to see how it works? As a child, Grace Hopper took apart five alarm clocks in a row, trying to figure out how all the pieces fit together. As an adult, she joined the Naval Reserve during World War II and worked on the world's first large-scale computer. After the war, Hopper served on a committee organized by the Department of Defense to create a standard computer language. That language, Common Business-Oriented Language, or COBOL, quickly became popular. How did a curious little girl grow up to become the "Grandmother of COBOL"? Learn how her outstanding innovations changed the field of computer programming.

While many people are familiar with the Internet, online shopping, and basic computer technology, the scientists who pioneered this digital age are generally less well-known. A to Z of Computer Scientists, Updated Edition features 136 computer pioneers and shows the ways in which these individuals developed their ideas, overcame technical and institutional challenges, collaborated with colleagues, and created products or institutions of lasting importance. The cutting-edge, contemporary entries explore a diverse group of inventors, scientists, entrepreneurs, and visionaries in the computer science field. People covered include: Grace Hopper (1906–1992) Dennis Ritchie (1941–2011) Brian Kernighan (1942–present) Howard Rheingold (1947–present) Bjarne Stroustrup (1950–present) Esther Dyson (1951–present) Silvio Micali (1954–present) Jeff Bezos (1964–present) Pierre Omidyar (1967–present) Jerry Yang (1968–present)

In computer science, understanding problems and systems can be difficult and time consuming. In this book, readers will learn about decomposition, a technique used to break down computer problems and systems into parts that are easier to understand and work with. STEM topics from the Next Generation Science Standards are discussed throughout this informative text. Students will be surprised to learn they actually decompose problems in their daily lives without even realizing it.

Have you ever watched video of astronauts walking on the moon? Margaret Hamilton programmed software that helped get them there. As a girl, Hamilton loved math and science. She grew up during a time when very few women studied computer science, but Hamilton knew she wanted to write code. As an adult, she worked on NASA's Apollo program, creating computer programs to guide spacecraft to and from the moon. This included the 1969 Apollo 11 mission—the first spaceflight that landed humans on the moon. In 2016, Hamilton was awarded the Presidential Medal of Freedom for her work. Learn how Hamilton's passion for math and computers played a key role in space exploration.

Do you enjoy visiting animals at the zoo or playing with pets? As a child, Jane Goodall loved watching and interacting with animals. As an adult, she became a scientist working with chimpanzees in Africa. Goodall used unconventional research methods to observe chimpanzees in East Africa. She studied the chimpanzees' behavior and revealed their tool-making abilities. As Goodall grew older, she turned her attention to raising awareness about endangered species and inspiring individuals around the globe to take action. She is one of the world's best-known scientists and activists. But how did she get there? Find out how Goodall's passion for animals helped her become the face of conservationism.

As a young girl in the 1930s, Jean Bartik dreamed of adventures in the world beyond her family's farm in northwestern Missouri. After college, she had her chance when she was hired by the US Army to work on a secret project. At a time when many people thought women could not work in technical fields like science and mathematics, Jean became one of the world's first computer programmers. She helped program the ENIAC, the first successful stored-program computer, and had a long career in the field of computer science. Thanks to computer pioneers like Jean, today we have computers that can do almost anything.

Do you think science is fun and exciting? Bill Nye does. In fact, he wanted to become an astronaut, but NASA rejected his applications. Instead, Nye has spent his career helping other people understand science and showing them how cool science can be. Nye went to college to become a mechanical engineer, and he got a job working for an aircraft company. But soon, he began focusing more and more on a career in comedy. Eventually, he got his own popular TV show, called Bill Nye the Science Guy. Through songs, skits, and jokes, Nye taught a generation of young people that science is fascinating and important. Learn more about Nye's career as a comedian, TV personality, and passionate science educator.

Have you ever dreamed of going to outer space? When Sally Ride was a little girl, she watched on TV as astronaut John Glenn launched into space. Twenty years later, she became the first American woman to go to space. Ride had loved science since she was young. Some of her teachers thought she was wasting her time studying science, but she went on to earn her PhD in astrophysics anyway. When NASA's astronaut training program opened to women, Ride quickly applied. Some people thought women couldn't handle space flight. But Ride worked hard and proved them all wrong. Later, she became a physics professor and started her own business to encourage young people to study science. Learn more about Ride's career as a NASA astronaut and educator.

Have you ever wished that you could do something heroic to help your country? When Alan Turing was a boy, he was fascinated by math and science. Later, Turing's math skills would help Great Britain win World War II. Turing's parents and teachers thought he'd be better off dropping math in favor of more gentlemanly studies, such as literature and Latin. But he stuck with it, and by the start of World War II in 1939, he was ready to take on the biggest challenge his country faced: Nazi Germany. Turing put his advanced knowledge of math to work decoding secret German messages. His ideas not only helped Great Britain turn the tide of the war—they provided the foundation upon which much of modern computing and artificial intelligence is based.
