What We Are Reading Today: Dynamics of Planetary Systems

Author: SCOTT TREMAINE

Celestial mechanics—the study of the movement of planets, satellites, and smaller bodies such as comets—is one of the oldest subjects in the physical sciences. Since the mid-twentieth century, the field has experienced a renaissance due to advances in space flight, digital computing, numerical mathematics, nonlinear dynamics, and chaos theory, and the discovery of exoplanets. This modern, authoritative introduction to planetary system dynamics reflects these recent developments and discoveries and is suitable for advanced undergraduate and graduate students as well as researchers.

What We Are Reading Today: Michelangelo and Titian

Author: William E. Wallace

In 1529, Michelangelo was in Venice when he first met Titian, Venice’s famed painter of princes, gods, and goddesses. Coming face-to-face with Titian’s drama-infused, richly colored works, the creator of David and the Sistine Chapel ceiling realized he had met a worthy opponent. Twenty-five years later, Titian came to Rome to paint the pope, and the two met again. Painting in the Vatican, Titian experienced the full power of Michelangelo’s work and vowed to surpass the achievements of his older contemporary.

Michelangelo and Titian is the untold story of history’s greatest artistic rivalry, a competition between two monumental figures more admiring of one another than either would ever admit. William Wallace brings the world of the 16th century to life, and in particular its culture of gossip and intrigue.

Wallace challenges the established narrative of this relationship as mostly one-sided, with the younger artist in competition with the reigning master.
