A masterpiece of precision and artistry: Guillaume Henri Dufour’s Topographische Karte der Schweiz (1833–1863). Created at an impressive 1:100,000 scale, this 25-sheet national map set a new standard for scientific cartography in the 19th century. Steel-engraved with extraordinary detail, it uses delicate hachures to sculpt the Alps in three dimensions—capturing Switzerland’s dramatic terrain with remarkable clarity. Centered on the Bern Observatory and produced during a period of rapid technological progress, the map supported military planning, infrastructure, and national unity. See all sheets:

The Speed of the Earth returns to Burning Man 2026. Across a mile of open playa, bursts of light reveal something we can never feel: the Earth spinning beneath us at 1,156 feet per second. Created by Kevin Kelly, David Rumsey, Dean Putney, Seth Roche, and Sonny Roche, this year’s installation lifts the lights 10 feet above the playa and adds glowing trails to each burst—transforming the invisible speed of our spinning planet into a streak of light racing across the desert.
