Combining true stories from the worlds of history, science, and politics, describes how the use of seven elements--iron, carbon, gold, silver, uranium, titanium, and silicon--has changed the world for both the better and worse

Ecologies of Knowledge provides a comprehensive overview of issues relating to work, politics, and the latest perspectives on the role of materials, feminism, "nonhumans," and work practices as shaping scientific and technical knowledge. In addition to theoretical contributions, the authors cover biotechnology, computing, representations and space, aerospace engineering, and a variety of ethical perspectives and controversies in these domains.

Feminist, educator, Quaker, and physicist, Ursula Franklin has long been considered one of Canada's foremost advocates and practitioners of pacifism. The Ursula Franklin Reader: Pacifism as a Map is a comprehensive collection of her work, and demonstrates subtle, yet critical, linkages across a range of subjects: the pursuit of peace and social justice, theology, feminism, environmental protection, education, government, and citizen activism. This thoughtful collection, drawn from more than four decades of research and teaching, brings readers into an intimate discussion with Franklin, and makes a passionate case for how to build a society centered around peace.

As a distinguished scientist, pacifist, and feminist, Ursula Franklin has been regularly invited by diverse groups to share her insights into the social and political impacts of science and technology. This collection contains twenty-two of Franklin's speeches and five interviews from 1986 to 2012 that have been retrieved and restored from audio and visual recordings with the help of her collaborator, Jane Freeman. These speeches and interviews, available here in print for the first time, stress the increased need for discernment and principled dialogue among Canadians. Although civic life for many Canadians has changed drastically in the past five decades, the basic principles of building and maintaining peaceful communities remain unchanged. Addressing practices of education, research, and civic life, Franklin looks to the past as well as the future to suggest collective ways of cultivating discernment and of advancing human betterment. As a whole, the collection reveals the evolution of Franklin's perspective: a perspective that is further elaborated in her afterthoughts that form the book's introduction and conclusion. Although her speeches and interviews are often critical of the status quo, Ursula Franklin Speaks is a fundamentally optimistic book, grounded in the conviction of the human capacity for compassion and understanding.

Bigger and fatter than all the other microbes in the valley. Wilton feels ostracised and out of place. But even more worryingly, their world has become unhealthy and toxic with mass illness and flash storms. Setting out to find out what is wrong, Wilton meets Algy, a tiny microbe small enough to sit on his shoulder (and take refuge in his guts) who accompanies Wilton on his quest. Taking a wrong turn in an effort to escape some killer fungus, they inadvertently end up outside - and discover (thanks to some helpful bacteria) that the world in which they live is actually one giant organism called Janet.
