Perturbation theory comprises mathematical methods that are used to find an approximate solution to a problem which cannot be solved exactly. (It is closely related to methods used in numerical analysis, which are ancient.) The earliest use of perturbation theory was to deal with the otherwise...
The interactions of light and matter with spacetime, as predicted by general relativity, can be studied using the new type of artificial optical materials that feature extraordinary abilities to bend light. Light is also known as electromagnetic radiation. This research creates a link between...

In celestial mechanics, for bound orbits in a spherical potential, the definition above is informally generalized. When the apocenter distance is close to the pericenter distance, the orbit is said to have low eccentricity; when they are very different, the ...
Celestial mechanics is the branch of astronomy that deals with the motions of celestial objects. The field applies principles of physics, historically classical mechanics, to astronomical objects such as stars and planets to produce ephemeris data. Orbital mechanics (astrodynamics) is ...
Classical mechanics was traditionally divided into three main branches: * Statics, the study of equilibrium and its relation to forces * Dynamics, the study of motion and its relation to forces * Kinematics, dealing with the implications of observed motions ... Celestial motion without additional forces such as thrust of a rocket, is governed by gravitational acceleration of masses due to other masses. A simplification is the ”n”-body problem, where the problem assumes some number ”n” of spherically symmetric masses. In ...
For an object falling from infinity in a capture orbit, the time it takes from a given position to fall to the central point mass is the same as the free-fall time, except for a constant frac{4}{3pi} ≈ 0.42. Category:Celestial ...
During the first half of the twentieth century, chaotic behavior in mechanics was recognized (as in the three-body problem in celestial mechanics), but not well-understood. The foundations of modern quantum mechanics were laid in that period, essentially leaving aside the ...
In 1947, there began an intense period of cooperative research on celestial mechanics between Clemence’s office, Eckert’s group at Columbia and Yale University Observatory, under the direction of Dirk Brouwer, a former collaborator of Eckert’s on punched cards. Adapted from ...
Boulding is widely known for his criticism of mainstream economists’ use of equilibrium analysis and, in particular, for the profession’s acceptance of, what Boulding calls, “Samuelson’s dynamics” (originating with the Foundations (1947)). To appreciate his position, it is important to ... symplectic integrator (SI) is a numerical integration scheme for a specific group of differential equations related to classical mechanics and symplectic geometry. Symplectic integrators form the subclass of geometric integrators which, by definition, are canonical transformations. They are widely used ...
In (1910) he published “Discrete elements of matter and radiation”, “Corrientes marinas” (1941) and, to gain entry to the Royal Academy of the Spanish Language, the volume “Neologismos, arcanismos in plàtica de ingenieros” (1946). As an encyclopedist, he authored several ...
Sokolov did research on the ”n”-body problem for nearly 50 years. He summarized his work in the 1951 book ”Singular trajectories of a system of free material points” (Russian). He did research on functional equations and on such practical problems ...
He was born in 1820 in Argenteuil, France. He occupied the chair of celestial mechanics at the Sorbonne. Excelling in mathematical analysis, he introduced new methods in his account of algebraic functions, and by his contributions to celestial mechanics advanced ...Who in the world are Kozai and Shipton and what do they have to do with 2012? Two very different people from very difficult cultures and time, but with a similiar idea and concept .Page 1 of 11
