You may hear someone say, “That storm had a lot of force” or “Mrs. Larsen is the force behind the school dance.” But what exactly is a force in science? In science, a force is a push or a pull. All forces have two properties: direction and size. A new ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
