Tout est lié: végétaux, insectes et animaux vivent en parfaite symbiose. C'est ainsi qu'un loup peut modifier le cours d'une rivière, que certains petits arbres produisent des substances répulsives pour dissuader les cerfs de les manger ou qu'une forêt fabrique des nuages. Toutefois, comme dans les subtils rouages d'une horloge, une vétille peut dérégler les mécanismes mis en place dans la nature.

Avec cette somme sur la nature du langage, Charles Taylor offre à ses lecteurs le livre qui était présent en arrière-plan de ses travaux précédents, notamment «Les Sources du moi» et «L'Âge séculier». En s'appuyant sur quatre décennies de réflexions et de recherches, il démontre comment, grâce au langage, l'être humain se découvre et se révèle au monde et aux autres. Au cours de sa longue histoire, la philosophie occidentale s'est divisée en deux camps à propos de la nature du langage.

Joseph-Armand Bombardier est né le 16 avril 1907 en Estrie. Dès treize ans, il démontre un réel talent d'inventeur. À 17 ans, le jeune homme quitte son village natal de Valcourt pour Montréal, où il espère parfaire ses connaissances en suivant des cours du soir en mécanique et en électricité automobile. C'est lui qui mettra au point la célèbre autoneige B7 en 1937. D'autres inventions le feront connaître à travers le Canada et poseront les assises de la compagnie multinationale qui porte encore aujourd'hui son nom.

Environmental Activism on the Ground draws upon a wide range of interdisciplinary scholarship to examine small scale, local environmental activism, paying particular attention to Indigenous experiences. It illuminates the questions that are central to the ongoing evolution of the environmental movement while reappraising the history and character of late twentieth and early twenty-first environmentalism in Canada, the United States, and beyond. This collection considers the different ways in which Indigenous and non-Indigenous activists have worked to achieve significant change.

By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of the oft-invisible world around us. Microbes are everywhere: in the soil and oceans, in snow, and inside our bodies. But in Antony van Leeuwenhoek's time, people believed that what they saw with their own eyes was all that existed in the world. How did a simple tradesman - who didn't go to college or speak English or Latin like all the other scientists - change everyone's minds?

Before John Glenn orbited the Earth or astronauts walked on the moon, a group of dedicated female mathematicians known as "human computers" used their knowledge, pencils, adding machines, and writing paper to calculate the orbital mechanics needed to launch spacecraft. Katherine Johnson was one of these mathematicians who used trajectories and complex equations to chart the space program. Even as Virginia's Jim Crow laws were in place in the early 1950s, Katherine worked analyzing data at the NACA (later NASA) Langley laboratory.

When you drop a box of unwanted items off at the local thrift store, where do they go? Probably across the country-or even halfway across the world-to people and places eager to reuse what you don't want. In Secondhand, Adam Minter delves into the vast, multibillion-dollar industry that resells used stuff around the world. He follows the trail of unwanted objects from the closets, garages, and storage units of Middle America to epic used-goods markets in Canada, Mexico, Japan, Ghana, India, Malaysia, and beyond.
