Cosmos: a Sketch of the Physical Description of the Universe

Late in a long life of exploration, Alexander von Humboldt tried to gather everything then known about the natural world into a single grand vision. His survey moves from distant nebulae and the structure of the heavens down to the Earth’s climates, volcanoes, plants, and magnetic forces, insisting that nature is one interconnected whole. Humboldt writes for the general reader as much as the specialist, blending precise observation with a genuine sense of wonder at the unity of it all. The book was a sensation across Europe and shaped how the nineteenth century imagined science itself. This edition presents his sweeping account of the physical universe.
