Earth Core Spins

The book progresses logically, starting with an introduction to Earth's interior and the history of inner core research. It then explains how seismic waves are used to probe the inner core's structure and rotation. It further delves into the evidence for differential rotation, examining various seismic waves and mathematical models.

The book culminates by discussing potential driving forces behind inner core rotation, such as gravitational coupling with the mantle. This approach offers a comprehensive understanding of the forces shaping our planet.
