Obsidian and the Birds: an Odyssey of Wonder From the Aztecs to the Quantum World – the Marginalian

A journey through the ruins of Teotihuacán becomes a meditation on the limits of human knowledge and the deeper mysteries that outlast civilizations. The same volcanic obsidian that built an ancient metropolis - lustrous, versatile, economically transformative - also contained magnetite, the mineral that would eventually guide Spanish conquistadors across oceans to destroy the descendants of those who first worked it. Meanwhile, warblers continue their migrations over these ruins, navigating by forces science can measure but not fully explain, their magnetic sense reminding us that "the perception of the magnetic field remains the only sense for which the sensory mechanism and its location still remain unknown." What looks like progress - our temples and theorems, our instruments and theories - is revealed as something humbler: the creative restlessness that springs from confronting a mystery of which we are inextricably a part. The birds knew then what they know now, while empires that mistook themselves for endpoints have returned to dust.
