In this episode of The Dead Scientists, we dive into Richard Feynman’s exploration of torque in three dimensions. While the principles of torque and angular momentum in two dimensions may seem familiar, Feynman expands these concepts to encompass the complexities of three-dimensional space.

Feynman introduces the use of vectors to represent torque, explaining how the direction of the vector is always perpendicular to the plane of torque. He illustrates this with equations that show how torque transforms across different coordinate systems, providing a deeper understanding of rotational dynamics.

The episode culminates in an analysis of precession—the fascinating tilting motion seen in spinning objects like gyroscopes. Feynman applies the principles of torque and angular momentum to break down this phenomenon, offering a clear and insightful look at the underlying physics behind precessional motion.

Whether you’re a physics enthusiast or simply curious about the forces that govern motion in three dimensions, this episode provides an engaging and accessible exploration of one of the most intriguing aspects of rotational dynamics.
