Raoul Perrin, a French engineer, is known for the Perrin numbers in mathematics. The Perrin numbers form a doubly infinite constant-recursive integer sequence with the characteristic equation x3 = x + 1. They are closely related to the Padovan sequence, similar to how the Lucas numbers are related to the Fibonacci sequence. The Perrin numbers are defined by a specific recurrence relation and can be expressed as sums of the three initial terms. Raoul Perrin's contribution to the field of mathematics through the development and study of the Perrin numbers has been significant, and his work continues to be studied and recognized in mathematical research and academia.

Jean-Baptiste Perrin, a prominent figure in hydrodynamics, is renowned for his groundbreaking work on the Perrin friction factors. These factors are pivotal in adjusting the translational and rotational friction of rigid spheroids in comparison to spheres of the same volume. Spheroids, which are essentially ellipsoids of revolution, are characterized by their axial ratio, denoted as p = (a/b), where a represents the axial semiaxis and b the equatorial semiaxis. In prolate spheroids, p > 1, while in oblate spheroids, p < 1. The Perrin S factor, a crucial component in the equations related to spheroids, is defined differently for prolate and oblate spheroids, as well as for spheres. Perrin's contributions have significantly advanced the understanding of fluid dynamics and continue to play a crucial role in related research and applications.
