From the time he was a small boy in Vermont, Wilson Bentley saw snowflakes as small miracles. And he determined that one day his camera would capture for others the wonder of the tiny crystal. Bentley's enthusiasm for photographing snowflakes was often misunderstood in his time, but his patience and determination revealed two important truths: No two snowflakes are alike; and each one is startlingly beautiful.

When Orville Wright (1871-1948) and his brother Wilbur set out to solve the problem of flight, they recognized that success would come with careful observation, perseverance, and ingenuity. From experiments in their Dayton, Ohio, bicycle shop to test flights over the beaches of Kitty Hawk, North Carolina, the amateur aviation enthusiasts risked their lives and worked tirelessly to solve the problems that had stumped the world's best scientists.

Alan Shepard's boyhood fascination with flight led him from constructing model airplanes in his grandfather's basement to attaining national hero status in the race to space. Rooted in hard work and education, this pioneer's dreams of flight came true as he became not only the first American launched into space but, later, one of the privileged few to walk on the moon. When he wasn't soaring above the clouds, astronaut Alan Shepard used his expertise to benefit others, raising money to fuel the dreams of science students and guiding NASA missions.

Cuando José Hernández Moreno tenía 10 años, en 1972, vio aterrizar en la Luna el Apollo 17 en la televisión en blanco y negro de su familia y supo que sería astronauta cuando fuese mayor. Más tarde, aquella noche, se lo contó a su padre y se quedó sorprendido cuando este le dijo: «Puedes hacerlo, m'ijo».

George Washington Carver began life as a slave in the tumultuous world of pre - Civil War Missouri. After the war, the orphaned Carver worked as a farmer, a hotel cook, and a laundryman while pursuing an education. As a professor at the Tuskegee Normal and Industrial Institute, Carver spearheaded the initiative to cultivate peanuts, soybeans, and sweet potatoes to revive the South's dismal agricultural economy. He is most remembered for the invention of peanut butter.

Formaldehyde, borax, salicylic acid. Today these chemicals are used in embalming fluids, cleaning supplies, and acne medications. But just over a hundred years ago, they were routinely added to all kinds of food by unregulated and unethical companies. Noted science and history writer Gail Jarrow introduces listeners to the relentless work of U.S. government chemist Dr. Harvey Washington Wiley, who mounted a thirty-year campaign to protect consumers from harmful food and drugs. As part of his research, he tested food additives by serving them to a squad of volunteers—the poison eaters.

What was Isaac Newton like? Secretive, vindictive, withdrawn, obsessive, and oh, yes, brilliant. His imagination was so large that, just “by thinking on it”, he invented calculus and figured out the scientific explanation of gravity. Yet Newton was so small-minded that he set out to destroy other scientists who dared question his findings. This compelling portrait of Newton, contradictions and all, places him against the backdrop of 17th-century England, a time of plague, the Great Fire of London, and two revolutions.

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.

Katherine knew it was wrong that African Americans didn't have the same rights as others - as wrong as 5+5=12. She knew it was wrong that people thought women could only be teachers or nurses - as wrong as 10-5=3. And she proved everyone wrong by zooming ahead of her classmates, starting college at 15, and eventually joining NASA, where her calculations helped pioneer America's first manned flight into space, its first manned orbit of Earth, and the world's first trip to the moon!

You know the Super Soaker. It's one of the top 20 toys of all time. And it was an accidental discovery that brought it into being. Trying to create a new cooling system for refrigerators and air conditioners, inventor Lonnie Johnson instead created the mechanics for the iconic toy. A love of rockets, robots, and inventions and a mind for creativity were present in Lonnie Johnson's early life.

On the battlefields of World War I, soldiers are dying from infected wounds. A young doctor witnessing the devastation vows to find a cure. In his messy laboratory a decade later, he makes an accidental discovery – a miracle mould that kills bacteria. But try as he might, he cannot turn his amazing find into a useful medicine. This is the story of that chance discovery and the brilliant scientists who took Alexander Fleming's miracle mould and worked tirelessly to turn it into a treatment that doctors could use.

Although Orville and Wilbur Wright are celebrated today as heroes for their revolutionary contributions to science and engineering - they are acknowledged as the first men to successfully achieve powered, piloted flight - their success was hard-earned. In fact, it took the self-taught engineers years of work and dozens of crashes before they managed a single 12-second flight! In this first installment of the brand new Epic Fails series, Ben Thompson and Erik Slader take listeners through the Wright brothers' many mishaps and misadventures as they paved the way for modern aviation.

This book explores the world of Sigmund Freud, who, making it into the author's highly popular series due to his creation of a brand-new branch of medicine called psychoanalysis, introduced the world to such controversial theories as Oedipal complexes, the id, and the ego.

Jeanne Villepreux-Power was never expected to be a scientist. Born in 1794 in a French village more than 100 miles from the ocean, she pursued an improbable path that brought her to the island of Sicily. There, she took up natural history and solved the two-thousand-year-old mystery of how the argonaut octopus gets its shell. In an era when most research focused on dead specimens, Jeanne was determined to experiment on living animals. And to keep sea creatures alive for her studies, she had to invent a contraption to hold them: the aquarium.

How Do You Become the Richest Person in the World? Is it luck? Is it talent? Or is it something else? Elon Musk wasn’t born into wealth or success.

From a young age, Stephen Hawking had a strong sense of wonder and was full of questions about the world around him and the stars above. He would spend his whole life trying to figure out how the universe worked, including discovering truths about black holes and energy. And when he was diagnosed with a rare disease called ALS that destroys the nerve cells in the body, he would find his own mental energy to carry on with his studies even after his limbs and vocal chords stopped working. He became one of history's most influential scientists.
