By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of the oft-invisible world around us. Microbes are everywhere: in the soil and oceans, in snow, and inside our bodies. But in Antony van Leeuwenhoek’s time, people believed that what they saw with their own eyes was all that existed in the world. How did a simple tradesman - who didn’t go to college or speak English or Latin like all the other scientists - change everyone’s minds?

When Minecraft creator Markus Persson was young, he wasn't very interested in the games themselves. He was more interested in the programing instructions in the computer's manual. By the time Persson was eight years old, he was writing code for his own computer games. When he was 18, Persson landed his dream job as a video game programmer. In 2009, he designed Minecraft in a single weekend. In the game, players use blocks to build whatever they choose. Persson wanted to let players use their imaginations, and the idea paid off.

Have you ever used your imagination to solve a problem? When Albert Einstein was young, he was fascinated by the way magnetism made a compass work. As an adult, he used thought experiments to solve some of the universe's greatest mysteries. Einstein loved to think about math and science. He worked for a while at a patent office, but his mind wasn't focused on inventions. Instead, he thought about the universe. In 1905, Einstein's Special Theory of Relativity solved questions that scientists had grappled with for hundreds of years.

One thing that hasn't changed much at all in the last 10,000 years is the human brain. The relentless curiosity of the human mind, combined with our ability to solve problems, has resulted in huge innovation and change. Here, then, are some of the most revolutionary ideas of the last 300 years.

Following the success of the first Great Scientists title in the Junior Classics range, this collection features the lives of nine more remarkable scientists, with descriptions of their discoveries.

Throughout history, people have experimented, invented, and created new ways of doing things. Kid Innovators tells the stories of a diverse group of brilliant thinkers in fields like technology, education, business, science, art, and entertainment, reminding us that every innovator started out as a kid. Florence Nightingale rescued baby mice, Alan Turing was a daydreamer with terrible handwriting, and Alvin Ailey felt like a failure at sports.

In a time when people believed flying was impossible, Joseph and Etienne Montgolfier proved that the sky wasn’t the limit.

Do you like to gaze at the stars? So did the young Stephen Hawking. Eventually, he turned his fascination with the night sky into a career of trying to figure out how the universe began and how it works. As a child, Hawking loved the stars and he loved math class. In college, he studied physics and cosmology, or how the universe came to be. But then he was diagnosed with amyotrophic lateral sclerosis (ALS), a disease that shuts down the nerves that control muscles.

Both Thomas Edison and Henry Ford started off as insatiably curious tinkerers. That curiosity led them to become inventors - with very different results. As Edison invented hit after commercial hit, gaining fame and fortune, Henry struggled to make a single invention (an affordable car) work. Witnessing Thomas' glorious career from afar, a frustrated Henry wondered about the secret to his success.

David Karp developed Tumblr after he tried to start a blog and found the process daunting. With most platforms a blogger faces a huge, empty text box that begs to be filled with words. It was intimidating for a guy who'd never blogged before. Karp had the idea for tumblelogging - creating short blog posts - and built Tumblr as a platform. It lets users easily post both text and images, making Tumblr highly visual and expressive.

For every child who has ever looked up at the stars and asked, "What are they?" comes the story of a curious boy who never stopped wondering: Carl Sagan.

Did you know that it’s believed Galileo was scolded by the Roman Inquisition for sassing his mom? That Isaac Newton loved to examine soap bubbles? That Albert Einstein loved to collect joke books, and that geneticist Barbara McClintock wore a Groucho Marx disguise in public? With juicy tidbits about everything from favorite foods to first loves, the subjects of Kathleen Krull and Kathryn Hewitt’s Lives of the Scientists: Experiments, Explosions (and What the Neighbors Thought) are revealed as creative, bold, sometimes eccentric - and anything but dull.

Ada Lovelace was the daughter of Lord Byron, a poet, and Anna Isabella Milbanke, a mathematician. Her parents separated when she was young, and her mother insisted on a logic-focused education, rejecting Byron's mad love of poetry. But Ada remained fascinated with her father and considered mathematics poetical science.

Eddie Rickenbacker was a World War I Flying Ace, a Medal of Honor winner, and even a racecar driver. But did you know that his first attempt at flying was to ride his bicycle off the roof of his house while holding an umbrella?
