Modern Theory/Understanding of Hooke's Law:
say that the strain (deformation) of an elastic object or material is proportional to the stress applied to it
However, since general stresses and strains may have multiple independent components, the "proportionality factor" may no longer be just a single real number, but rather a linear map (a tensor) that can be represented by a matrix of real numbers.

Spring Force is very important to this world, and has many components used by people around the world, everyday.

Hookes's law is only a first order linear approximation to the real response of springs and other elastic bodies to applied forces.
In other words, it must eventually fail once the forces exceed some limit, since no material can be compressed beyond a certain minimum size, or stretched beyond a maximum size, without some permanent deformation or change of state.
Hooke's law is an accurate approximation for most solid bodies, as long as the forces and deformations are small enough.
used in all branches of science and engineering, and is the foundation of many disciplines such as seismology, molecular mechanics and acoustics. (used everyday around the world for many reasons)
the fundamental principle behind the spring scale, the manometer, and the balance wheel of the mechanical clock. ( hooke's law helped with many things to be made in the world today)
