Uranium

Z: 92
Mass: 238.029
Lifeforce: Earth

Sun-power in the reactor, annihilation in the bomb — the same atom. Uranium carries light and shadow undivided: the pendulum at its outermost point, Pendelmodus written into matter itself.

A terraced slope with laid stone foundations and visible roots; a figure sets a stone in place. — Plate · Earth Earth never hurries — it *holds*, stone by stone, whatever is meant to last.

Forged in neutron-star collisions. The heaviest element found in significant quantities on Earth, and the engine of every nuclear reactor.

Lab note · The heaviest element found on Earth in appreciable quantities; forged in neutron-star collisions.
