What''s more popular than Tumblr? This microblogging site has taken the Web by storm since its founding in 2007. Not much can top it when it comes to capturing its fans'' imaginations, except for perhaps its creator, David Karp. 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. Creating a different way to blog came naturally to Karp, who never does things by the book. At fifteen, he dropped out of school. At seventeen, he moved to Tokyo, holing up with a computer and fine-tuning his tech skills. He returned to the states to build a business—but to do that, he stretched the truth. He used a deep voice on the phone with potential clients so they wouldn''t guess how young he was. He didn''t tell anyone how little experience he had. Yet people could see he had a good thing going with Tumblr. The company quickly found support and grew into what it is today: a groundbreaking site for connection and creation. And as the mastermind behind it, Karp is sure to remain a figure to watch.

Abraham Lincoln was born to poor parents, in a log cabin on the western frontier of a young nation. The unity of the United States, which had been built on the ideal that all people are created equal, was cracking under the heavy yoke of slavery. As Lincoln embarked on his presidency, the slaveholding states in the South left the Union, causing him to face the American Civil War. Lincoln said the war was no less than a fight to save government of the people, by the people, and for the people. Though his life was cut short, Lincoln''s leadership and his written words continue to inspire Americans.

Until the mid-1990s, scientists only guessed that the universe held exoplanets, or planets beyond our solar system. But using advanced physics and powerful telescopes, scientists have since identified more than three thousand exoplanets. This work has revealed fascinating worlds, including a planet that oozes lavalike fluids and a planet that glows bright pink.Even more fascinating, scientists think that some exoplanets might contain life. Many orbit in the Goldilocks zone, the region around a star that''s not too hot or too cold for liquid water, a key ingredient for life. This book examines exoplanets, the possibilities for life beyond Earth, and the cutting-edge technologies scientists use to learn about distant worlds.
