Friedmann Über die Krümmung des Raumes (in Zeitschrift für Physik 11, 1922); Über die Krümmung des Raumes (in Zeitschrift für Physik 16, 1923); Über die Möglichkeit einer Welt mit konstanter negative Krümmung des Raumes (in Zeitschrift für Physik 21, 1924).
    First editions, first impressions of Friedmann's four cosmological papers in which he correctly derived the solutions to Einstein's field equations to determine that the universe is expanding. A beautiful copy of this rare set, handsomely bound. Einstein believed the universe to be static, and had introduced the cosmological constant into his equations so that they described an unchanging universe. Learn More
