Actors, Athletes, and Astronauts
Political Amateurs in the United States Congress
David T. Canon
University of Chicago Press, 1990
The U.S. Congress is typically seen as an institution filled with career politicians who have been seasoned by experience in lower levels of political office. In fact, political amateurs have comprised roughly one quarter of the House of Representatives since 1930. The effect of amateurs' inexperience on their political careers, roles in Congress, and impact on the political system has never been analyzed in detail.

Written in a lucid style accessible to the nonspecialist, David T. Canon's Actors, Athletes, and Astronauts is a definitive study of political amateurs in elections and in Congress. Canon examines the political conditions that prompt amateurs to run for office, why they win or lose, and whether elected amateurs behave differently from their experienced counterparts. Challenging previous work which presumed stable career structures and progressively ambitious candidates, his study reveals that amateurs are disproportionately elected in periods of high political opportunity, such as the 1930s for Democrats and 1980s for Republicans.

Canon's detailed findings call for significant revision of our prevailing understanding of ambition theory and disarm monolithic interpretations of political amateurs. His unique typology of amateurism differentiates among policy-oriented, "hopeless," or ambitious amateurs. The latter resemble their professional counterparts; "hopeless" amateurs are swept into office by strong partisan motivations and decision-making styles of each type vary, affecting their degree of success, but each type of amateur provides a necessary electoral balance by defeating entrenched incumbents rarely challenged by more experienced politicians.

Why Robots Are the Future of Exploration
Donald Goldsmith, Martin Rees

A History Today Book of the Year

A world-renowned astronomer and an esteemed science writer make the provocative argument for space exploration without astronauts.

Human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. As our robot explorers grow more competent, governments and corporations must ask, does our desire to send astronauts to the Moon and Mars justify the cost and danger? Donald Goldsmith and Martin Rees believe that beyond low-Earth orbit, space exploration should proceed without humans.

In The End of Astronauts, Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system. In space humans require air, food, and water, along with protection from potentially deadly radiation and high-energy particles, at a cost of more than ten times that of robotic exploration. Meanwhile, automated explorers have demonstrated the ability to investigate planetary surfaces efficiently and effectively, operating autonomously or under direction from Earth. Although Goldsmith and Rees are alert to the limits of artificial intelligence, they know that our robots steadily improve, while our bodies do not. Today a robot cannot equal a geologist’s expertise, but by the time we land a geologist on Mars, this advantage will diminish significantly.

Decades of research and experience, together with interviews with scientific authorities and former astronauts, offer convincing arguments that robots represent the future of space exploration. The End of Astronauts also examines how spacefaring AI might be regulated as corporations race to privatize the stars. We may eventually decide that humans belong in space despite the dangers and expense, but their paths will follow routes set by robots.
