In classical physics, Lagrange and Hamiltonian mechanics are two equivalent formulations used to describe the motion of particles or systems. Both approaches are based on the principle of least action, but they use different mathematical formalisms. Lagrange mechanics uses generalized coordinates and velocities to derive equations of motion, while Hamiltonian mechanics uses generalized coordinates and momenta. Despite their differences, Lagrange and Hamiltonian mechanics are related through a mathematical transformation called the Legendre transformation, which allows one to derive the equations of motion in either formalism from the other.
The Green-Lagrange strain is a measure of deformation in materials that accounts for both stretching and shearing. It is significant in mechanics and materials science because it provides a more accurate description of how materials deform under stress compared to other strain measures. This helps engineers and scientists better understand the behavior of materials and design more efficient structures and products.
Stable Lagrange points in celestial mechanics are locations in a two-body system where the gravitational forces of the two bodies balance out, allowing a smaller object to orbit in a stable position relative to the larger bodies. These points are characterized by being at fixed distances and angles from the two main bodies, and any small perturbations will cause the object to return to its original position.
Lagrange points are specific locations in space where the gravitational forces of two large bodies, such as a planet and a moon, balance out the centrifugal force of a smaller body, like a spacecraft. There are five Lagrange points in the Earth-Sun system, labeled L1 to L5. These points are stable and allow objects to orbit in a synchronized manner with the larger bodies, making them useful for spacecraft to conserve fuel and stay in position for extended periods of time.

The lagrange function, commonly denoted L is the lagrangian of a system. Usually it is the kinetic energy - potential energy (in the case of a particle in a conservative potential). The lagrange equation is the equation that converts a given lagrangian into a system of equations of motion. It is d/dt(\partial L/\partial qdot)-\partial L/\partial q.

The funamental difference is a legendre transformation that takes one from lagrange mechnaics to hamilton. More concretely, euler-lagrange generates second order diffeq's, where hamilton generates 2x first order differential eqs. I recommend landau lifshitz volume 1 for more details.
Anybody who knows a bit of math understands the genius and importance of Lagrange. he may be the greatest mathematics genius in history. His importance in modern physics (he is everywhere in quantum mechanics) is unique.
