... the Coulomb field there is going to be infinite in magnitude. Even for the extended case the field at the surface of the particle is going to be very large, since r will be very small. However we might find some comfort in the fact that, for a stationary particle (or indeed one in an inertial frame) ...

History of physics
Physics (from the Ancient Greek φύσις physis meaning ""nature"") is the fundamental branch of science that developed out of the study of nature and philosophy known, until around the end of the 19th century, as ""natural philosophy"". Today, physics is ultimately defined as the study of matter, energy and the relationships between them. Physics is, in some senses, the oldest and most basic pure science; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world. The other sciences are generally more limited in their scope and may be considered branches that have split off from physics to become sciences in their own right. Physics today may be divided loosely into classical physics and modern physics.
