Charles Ludwig retells Michael Faraday’s remarkable life story in fictionalized form. Here is the father of the electric motor, the dynamo, the transformer, the generator. Few persons are aware of the brilliant man’s deep Christian convictions and his determination to live by the Sermon on the Mount. For ages 12 to 15.

Einstein's astonishing theory of relativity transformed every aspect of physics-from the study of atoms to the study of stars. Relativity is described here in simple, accurate language that young readers can comprehend.

Electrical engineer and inventor Nikola Tesla (1856–1943) was indeed an electrical genius. In language suitable for both young and old, author Arthur J. Beckhard describes all aspects of Tesla’s personal and professional life, including Tesla’s childhood and his education at primary school, at the Higher Real Gymnasium, and at the Polytechnic Institute; his years working for the telegraphic engineering department of Austria, then as an engineer in Paris, and then as an employee of Thomas Edison in America; his substitution of alternating current for direct current—a simpler and more economical method of converting electrical into mechanical energy; his rotary magnetic field, which was used in transmitting the power of Niagara Falls to nearby cities; his independent research at his own electrical laboratories in New Your City; and much more. Originally published in 1959 as part of Messner Publications' "Men of Science" series

Before John Glenn orbited the earth, or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as “human computers” used pencils, slide rules, and adding machines to calculate the numbers that would launch rockets, and astronauts, into space.

This book brings to life the stories of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden, who lived through the Civil Rights era, the Space Race, the Cold War, and the movement for gender equality, and whose work forever changed the face of NASA and the
country.

As a young girl, Katherine Johnson showed an exceptional aptitude for math. In school she quickly skipped ahead several grades and was soon studying complex equations with the support of a professor who saw great promise in her. But ability and opportunity did not always go hand in hand. As an African American and a girl growing up in an era of brutal racism and sexism, Katherine faced daily challenges. Still, she lived her life with her father’s words in mind: “You are no better than anyone else, and nobody else is better than you.”

Computers touch our lives everyday, in countless ways, but how do they know what to do? How do we communicate with them and they with each other? Language! Grace Hopper was a pioneer in computer programming, a woman whose scientific research led to computer-language tools and technology still in use today. Her story is filled with trial and error, and readers can follow the journey step by step.

Jane Goodall, born in London, England, always loved animals and wanted to study them in their natural habitats. So at age twenty-six, off she went to Africa! Goodall's up-close observations of chimpanzees changed what we know about them and paved the way for many female scientists who came after her. Now her story comes to life in this biography with black-and-white illustrations throughout.

Can you imagine how different life would be without the printing press? It's unlikely you'd ever have held a book. And your clothes would look very different without the invention of spinning and sewing machines. Without boats, trains, and planes, even our diets would be changed.Read about the fascinating creators of these inventions and the struggles they faced. Some got rich, some fought for every penny, but they all changed the way we live our lives today. Inventors profiled in this collection include James Watt (the steam engine), Elias Howe (the sewing machine), Cyrus McCormick (the reaper), John Gutenberg (the printing press), Alexander Graham Bell (the telephone) as well as many more.This reprinting is complete and unabridged featuring all the original illustrations and reformatted text for easier reading.
