In two southern Illinois towns only forty miles apart, explosions killed 111 men at the Centralia No. 5 mine in 1947 and 119 men at the New Orient No. 2 mine in West Frankfort in 1951. Robert E. Hartley and David Kenney explain the causes of the accidents, identify who was to blame, and detail the emotional impact the disasters had on the survivors, their families, and their communities.

Benjamin Franklin was one of the preeminent scientists of his time. Driven by curiosity, he conducted cutting-edge research on electricity, heat, ocean currents, weather patterns, chemical bonds, and plants. But today, Franklin is remembered more for his political prowess and diplomatic achievements than his scientific creativity. In this incisive and rich account of Benjamin Franklin's life and career, Richard Munson recovers this vital part of Franklin's story.

The workshop revolutionaries who made our world have never had the attention afforded the political revolutionaries who founded this nation. But it has been these innovators, in small-town attics and on the Mississippi, in Silicon Valley and the wheat fields of Kansas, in a Black woman's beauty parlor and a Dayton bicycle shop, who set America on a course to attain a standard of living unprecedented in the history of the world.

At the onset of the American Revolution, the British expected to quell the rebellion quickly with a show of overwhelming force. In an experiment in asymmetric warfare, David Bushnell created the first submarine vessel designed specifically “for the destruction of vessels of war”. In Turtle, the authors provide new insight into Bushnell’s “engine of devastation”, tracing the history of undersea warfare before Bushnell and the origin of the many innovations Bushnell understood would be necessary for conducting a covert submarine attack.

In this remarkable culinary biography, Rae Katherine Eighmey presents Benjamin Franklin's experimentation with food throughout his life. At age 16, he began dabbling in vegetarianism. In his early 20s, citing the health benefits of water over alcohol, he convinced his printing press colleagues to abandon their traditional breakfast of beer and bread for "water gruel", a kind of porridge he enjoyed. Franklin is known for his scientific discoveries, including electricity and the lightning rod, and his curiosity and logical mind extended to the kitchen.

How did the colonists of Jamestown and Maryland live and die? Forensic anthropology provides an incredible array of answers. Scientists can look into a grave and determine the skeleton's gender, age at time of death, nationality, and sometimes even economic standing within minutes. Laboratory studies can provide cause of death information.

Benjamin Franklin's wide range of activities and interests opened the doors of the world to him. Printer, inventor, philosopher, ambassador, champion of liberty - his influence has been felt by every American generation. And to everything he touched, including this autobiography, Franklin brought originality and wit.

Since the 1930s, the scale of scientific endeavors has grown exponentially. The birth of Big Science can be traced to Berkeley, California, nearly nine decades ago, when a resourceful young scientist pondered his new invention and declared, "I'm going to be famous!" Ernest Orlando Lawrence's cyclotron would revolutionize nuclear physics, but that was only the beginning of its impact.This is the incredible story of how one invention changed the world and of the man principally responsible for it all. Michael Hiltzik tells the riveting full story here for the first time.

Throughout the course of history, civilization has been blessed by strong-minded men and women who have impacted our world in extraordinary ways. Their imprint upon humanity is beyond dispute. And many would contend that they were no less than the result of Divine Providence - a gift of God to the human race. The Mark of a Giant examines the lives and contributions of seven men and women who changed the world: Abraham of Ur, Pericles, the Apostle Paul, Sir Isaac Newton, Marie Curie, Martin Luther King Jr., and Mother Teresa.

Award-winning author Philip Dray delves into the lesser-known side of an American icon in Stealing God's Thunder. Benjamin Franklin, more often viewed as a statesman and founding father than as a man of science, challenged religion, science, and reason with his inventions. But in a time when everything was blamed on sin, it was the lightning rod, Franklin's attempt to control the heavens, that caused the greatest controversy.

Central to America's idea of itself is the character of Benjamin Franklin. We all know him, or think we do: In recent works and in our inherited conventional wisdom, he remains fixed in place as a genial polymath and self-improver who was so very American that he is known by us all as the first American.

Albert Einstein ist der Inbegriff des Genies. Kein Wissenschaftler des 20. Jahrhundert hat unser Verständnis vom Universum so revolutioniert wie er. Neben den teils verschlungenen Wegen zu seinen Theorien, widmet sich das Hörbuch auch dem Menschen, der diese Wege beschritt. Es beschreibt, wie Einsteins Kindheit in Deutschland, seine Arbeit im Schweizer Patentamt, aber auch sein komplexer Charakter und die daraus folgenden familiären Begebenheiten den großen Wissenschaftler formten.

The Space Age began just as the struggle for civil rights forced Americans to confront the long and bitter legacy of slavery, discrimination, and violence against African Americans. Presidents John F. Kennedy and Lyndon Johnson utilized the space program as an agent for social change, using federal equal employment opportunity laws to open workplaces at NASA and NASA contractors to African Americans while creating thousands of research and technology jobs in the Deep South to ameliorate poverty.

The United States is experiencing a profound crisis when it comes to mental health care. In a recent Senate Committee on Finance hearing on youth mental health, US Surgeon General Dr. Vivek Murthy shared that Americans wait 11 years, on average, between onset of symptoms and first receiving treatment. The consequences are plain to see: higher suicide and drug overdose rates, more Americans without a safe place to sleep, more children experiencing depression and anxiety. The house is on fire, and the nation is short on firefighters equipped to put out the blaze.

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.

Thank you for the opportunity to contribute to today’s discussion on federal perspectives to secure the nation’s infrastructure.

The security of these systems and data is vital to public confidence and national security, prosperity, and well-being.

At least as far back as the ancient myth of Icarus, humans longed to fly - but it wasn't until December 17, 1903, on the windy dunes of Kitty Hawk, North Carolina, that the dream finally came true. And it was all thanks to Orville and Wilbur Wright, two former bicycle mechanics who built their first toy plane - a rubber-band powered rotary - when they were just children.
