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.

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.

Physical infrastructure in the United States is crumbling. The American Society of Civil Engineers has, in its latest report, given American roads and bridges a grade of D and C+, respectively, and has described roughly 65,000 bridges in the United States as 'structurally deficient'. This crisis - and one need look no further than the I-35W bridge collapse in Minnesota to see that it is indeed a crisis - shows little sign of abating short of a massive change in attitude amongst politicians and the American public.

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.

On March 14, 1889, Susan La Flesche received her medical degree - becoming the first Native American doctor in US history. She earned her degree 31 years before women could vote and 35 years before Indians could become citizens in their own country. This is the story of an Indian woman who effectively became the chief of an entrenched patriarchal tribe, the story of a woman who crashed through thick walls of ethnic, racial, and gender prejudice and then spent the rest of her life using a unique bicultural identity to improve the lot of her people.

Bill McKibben, examines the dangers inherent in an array of technologies that threaten not just our survival, but our identity. Imagine a future where lab workers can reprogram human embryos to make our children "smarter" or "more sociable" or "happier." Enough examines such possibilities, and explains how we can avoid their worst consequences while still enjoying the fruits of our new scientific understandings.

At the peak of his power, in the 1940s and 1950s, William Francis Gibbs was considered America's best naval architect. His quest to build the finest, fastest, most beautiful ocean liner of his time, the S.S. United States, was a topic of national fascination. When completed in 1952, the ship was hailed as a technological masterpiece at a time when "made in America" meant the best.

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 Port of Los Angeles is all around us. Objects we use on a daily basis pass through it: furniture, apparel, electronics, automobiles, and much more. Yet despite its centrality to our world, the port and the story of its making have been neglected in histories of the United States. In A Machine to Move Ocean and Earth, historian James Tejani corrects that significant omission, charting the port's rise out of the mud and salt marsh of San Pedro estuary.

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.

Why GAO did this study. The internet is a global system of interconnected networks used by billions of people across the world to perform personal, educational, commercial, and governmental tasks. The US Government over time has relinquished its oversight role of the internet. A global, multistakeholder community made up of many organizations shapes internet policy, operations, and security. But the ongoing and increasing reliance on the internet underscores the need to understand the risks to its underlying architecture.

Federal agencies with a lead role to assist and protect one or more of the nation’s 16 critical infrastructures are referred to as sector risk management agencies (SRMAs). The SRMAs for three of the 16 have determined the extent of their sector’s adoption of the National Institute of Standards and Technology’s (NIST) Framework for Improving Critical Infrastructure Cybersecurity (framework). In doing so, lead agencies took actions such as developing sector surveys and conducting technical assessments mapped to framework elements.
