The moons wander azimuthally about the Lagrange points, with Polydeuces describing the largest deviations, moving up to 32° away from the Saturn–Dione L 5 point. One version of the giant impact hypothesis postulates that an object named Theia formed at the Sun–Earth L 4 or L 5 point and crashed into Earth after its orbit destabilized ...
Joseph-Louis Lagrange [a] (born Giuseppe Luigi Lagrangia [5] [b] or Giuseppe Ludovico De la Grange Tournier; [6] [c] 25 January 1736 – 10 April 1813), also reported as Giuseppe Luigi Lagrange [7] or Lagrangia, [8] was an Italian mathematician, physicist and astronomer, later naturalized French.
After Newton, Joseph-Louis Lagrange attempted to solve the three-body problem in 1772, analyzed the stability of planetary orbits, and discovered the existence of the Lagrange points. Lagrange also reformulated the principles of classical mechanics, emphasizing energy more than force, and developing a method to use a single polar coordinate ...
Given a set of generalized coordinates q, if we change these variables to a new set of generalized coordinates Q according to a point transformation Q = Q(q, t) which is invertible as q = q(Q, t), the new Lagrangian L′ is a function of the new coordinates ′ (, ˙,) = ((,), ˙ (, ˙,),), and by the chain rule for partial differentiation ...
In physics, specifically classical mechanics, the three-body problem is to take the initial positions and velocities (or momenta) of three point masses that orbit each other in space and calculate their subsequent trajectories using Newton's laws of motion and Newton's law of universal gravitation.

He also wrote over 4500 letters and hundreds of manuscripts. It has been estimated that Leonhard Euler was the author of a quarter of the combined output in mathematics, physics, mechanics, astronomy, and navigation in the 18th century, while other researchers credit Euler for a third of the output in mathematics in that century.

Georges Henri Joseph Édouard Lemaître (/ l ə ˈ m ɛ t r ə / lə-MET-rə; French: [ʒɔʁʒ ləmɛːtʁ] ⓘ; 17 July 1894 – 20 June 1966) was a Belgian Catholic priest, theoretical physicist, and mathematician who made major contributions to cosmology and astrophysics. [1]
