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.

Throughout the 1960s and 1970s, a diverse group of teachers and students working together on academic computing systems conducted many of the activities we now recognize as personal and social computing. Joy Rankin draws on detailed records to explore how users exchanged messages, programmed music and poems, fostered communities, and developed computer games like The Oregon Trail. These unsung pioneers helped shape our digital world, just as much as the inventors, garage hobbyists, and eccentric billionaires of Palo Alto.

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.

Thomas Jefferson praised Tom Paine as the greatest political writer of the age. The author of Common Sense and Rights of Man, Paine helped make revolutions in America and France. But beyond his inspiring calls to action, Paine harbored a deeper political vision for his adopted country. It was embodied in an architectural project that he spent decades planning: an iron bridge to span the Schuylkill River at Philadelphia.

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.

As the 2022 National Security Strategy and National Defense Strategy (NDS) makes clear, the United States is in the midst of a decisive decade where the terms of geopolitical competition between the world’s major powers will be set. The Department of Defense (DoD) will advance its priorities in three interlocking ways– through integrated deterrence, campaigning, and by building enduring advantages. Accelerated technology advancement and innovation are key elements to achieving DoD priorities through these strategic ways, and to ensure our national security over the long term.

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.

Albert Einstein ist der Inbegriff des Genies. Kein Wissenschaftler des 20. Jahrhundert hat unser Verständnis vom Universum so revolutioniert wie er.

The Cherokees might be the most famous tribe in the country. If so, the person most responsible for it is Sequoyah, whose invention of the Cherokee syllabary also played a prominent role in facilitating the assimilation between the Cherokee and Americans. Sequoyah began work on devising the writing and reading system around 1809, and it was instantly popular among Cherokees, to the extent that it was being used in written publications among the tribe by the 1820s. The syllabary has been in use ever since, both within the tribe and among outsiders.

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.
