Cada tipo de roca contiene una historia que se entrelaza con la nuestra, moldeando la vida de la Tierra y la de sus habitantes de forma invisible y poderosa. La Tierra se ha reinventado a sí misma durante más de cuatro mil millones de años, y las rocas han custodiado el registro de toda su...

Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet. Contrary to their reputation, rocks have eventful lives—and they intersect with our own in surprising ways.

Marcia Bjornerud's life as a geologist has coincided with an extraordinary period of discovery. From an insular girlhood in rural Wisconsin, she found her way to an unlikely career studying mountains in remote parts of the world. As one of few women in her field, she witnessed the shift in our understanding of the Earth, from solid object to an entity in a constant state of transformation. In the most tumultuous times of her own life, a deep understanding of our rocky planet imbued her life with meaning.

From the author of Turning to Stone, a mediation on the stories that rock can tell us about the deep history of our planet To many of us, the Earth’s crust is a relic of ancient, unknowable history. But to a geologist, the Earth’s crust, and every stone within it, is a richly illustrated...

Few of us have any conception of the enormous timescales in our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.
