Nikola Tesla was a major figure in the world in which he lived. As the 19th century gave way to the 20th, it was Tesla who would contribute to some of the world's most amazing inventions. It was Tesla's theories, patents, and experiments that would pave the way for the digital, wireless world we are so familiar with today. Tesla didn't enjoy the high honors bestowed on so many of his contemporaries, yet he enjoyed the power of knowing that it was his inventions that were powering the world, literally.

The Spanish Empire was the first truly global empire and the first to be described as one on which “the sun never sets.” It rapidly grew to become one of the largest and most powerful empires in the history of the world and brought us goods such as potatoes, chocolate, and chewing gum.

The creation of the Union of Soviet Socialist Republics (USSR) in 1922 was one of the defining events of the 20th century. This new federation, created to embody the ideals of communism and the notion of rule by the people, was intended to be different from any other nation in the world. This utopian vision inspired people around the world, and soon, communism became an international movement. However, the history of the Soviet Union did not develop in the way its originators envisaged.

The British Empire comprised a bewildering collection of colonies, dominions, protectorates, and mandated possessions that spanned the planet. This was the largest empire in world history, at its peak ruling over more than 400 million people and covering almost one-quarter of the total land mass of the Earth.

Many of us dream of finding instant wealth. Just imagine if you were able to go to a place where you could simply gather from the ground gold worth many thousands of dollars. Now imagine that at a time when the average wage for an unskilled worker was barely ten dollars per month.

Sojourner Truth was born a slave in 1797. One day, she decided she didn’t want to be a slave anymore and simply walked away from her master. Truth spent the rest of her life preaching and lecturing against slavery and for freedom and equality. While helping former slaves integrate into a free society, she lectured fervently against the discriminations against women, and especially African American women. Her speech “Ain’t I a Woman?” is considered one of the most riveting women’s rights speeches ever given.

Isaac Newton seemed to be a most unwanted child of the world. Ignored by his mother, scorned by contemporaries, seemingly at war with the world in which he lived, Newton turned his energies to things unseen. His laws of motion and law of universal gravitation would set the stage for a most extraordinary life. Follow along as you travel from a rugged stone farmhouse to Trinity College, Cambridge to the halls of London exhibitions where Newton found himself the celebrity of the age. Looking back on Aristotle, and inspired by all that Galileo had brought the world, Newton made his life work much of what is heralded as the modern age. He saw what no one else did, and his vision saw into the universe. See how he did it, and why.

Rosalind Franklin was what can only be called an overlooked genius. Although she was not fully credited for the feat at the time, her work led to major breakthroughs in our understanding of DNA. In fact, she took the first X-ray photo of DNA in all of its double helix glory. By the time her former colleagues were being showered with accolades for results they made at least partially based on her findings, Franklin would not be around to see it. Sadly, it’s believed that her use of X-ray equipment gave her terminal cancer, cutting her life short at age 37.

Wilbur and Orville Wright are two of the greatest innovators in history, and together they solved the centuries-old riddle of powered, heavier-than-air flight. Glenn Hammond Curtiss was the most talented machinist of his day; he first became the fastest man alive when he perfected the motorcycle, then turned his eyes toward the skies to become the fastest man aloft. But between the Wrights and Curtiss bloomed a poisonous rivalry and a patent war so powerful that it shaped aviation in its early years and drove one of the three men to his grave.

Two-time winner of the Pulitzer Prize David McCullough tells the dramatic story behind the story about the courageous brothers who taught the world how to fly: Wilbur and Orville Wright.

On December 17, 1903, at Kitty Hawk, North Carolina, Wilbur and Orville Wright's Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard. The Age of Flight had begun. How did they do it? And why?

Nikola Tesla pursued his ideas for wireless lighting and worldwide wireless electric power distribution in his high-voltage, high-frequency power experiments. Hear more about Tesla in this audiobook.

Thomas Edison was born into a hard-working but attentive family. He struggled in school and became deaf at an early age. Born on February 11, 1847, Edison would become, arguably, the best-known American inventor of all time. His invention of the light bulb was one of more than 1,000 patents he held during his lifetime. Others included the phonograph, the electrical grid, and motion pictures. His work changed the way we see and hear the world around us.

Obsessive, brilliant, and tortured, Nikola Tesla was lauded for his invention of the alternating current (AC) and other significant contributions to science. His claim that “harnessing the forces of nature was the only worthwhile scientific endeavor" both impressed and enraged the scientific community. Eventually his peers could no longer dismiss his eccentricities and began to view him as a crackpot - a potentially dangerous one.

When the Marines decided to buy a helicopter-airplane hybrid "tiltrotor" called the V-22 Osprey, they saw it as their dream machine. The tiltrotor was the aviation equivalent of finding the Northwest Passage: an aircraft able to take off, land, and hover with the agility of a helicopter yet fly as fast and as far as an airplane. Many predicted it would reshape civilian aviation. The Marines saw it as key to their very survival. Opponents called it one of the worst boondoggles in Pentagon history.

The flight of Apollo 11 made Aldrin one of the most famous persons on our planet, yet few people know the rest of this true American hero's story. In Magnificent Desolation, Aldrin not only gives us a harrowing first-person account of the lunar landing that came within seconds of failure and the ultimate insider's view of life as one of the superstars of America's space program, he also opens up with remarkable candor about his more personal trials - and eventual triumphs - back on Earth.
