# n-Body Problem Closed-Form Solution

The *n-Body Problem Closed-form Solution* monograph (is a freebie ebook), now the 4th Edition, is the

*principal*pdf file and its thrust is the presentation of the

*generalization*of

**NEWTON**'s

*Law of Universal Gravitation*in the form of an easy to use algorithm for calculating the interacting forces for any number of isolated bodies

Added to the principal Monograph, 2nd Edition, was the "*Planet Forces*" section which refers to **LIBESKIND**'s work**. ** One suggestion in this article is the electromagnetic energy flux issuing from the atomic nuclei is a cause of gravity (the flux however weak doesn't stop at the valence electron, but travels on)**.** The link for this phenomena may be** van der** **WAALS**, and/or like, long-range forces between atoms; and even for those atoms not in direct contact**.** See the short "* van der WAALS Forces and Gravity*" article

**.**The

*'s*

__n-Body Problem Closed-form Solution__*algorithm*may be used to determine those interaction forces

** ** ** Astronomy**,

**Parts 1, 2, 3**, and

**4**is a single monograph (divided up into four Sections), mainly serving as technical background, with some historical background given too, to augment the

**ebook**

*n*-body Problem**.**It has been completely rewritten and now identified as the

*2nd Edition*

**.**and

__Astronomy,__Part 1**2**, consists of a collection of essays about the

*Antikythera*astronomy machine, Greek astronomy,

**Aristotle**'s Physics, Islamic astronomy,

**Copernicus**,

**Galileo**,

**Bacon**versus

**Descartes**,

**NEWTON**, celestial mechanics, and more

**.**Specifically, in the Second section of

**Part 1**it explains how the Sun's wobble creates by gravitational forces a planetoid's translation acceleration

**.**And further, it hypothesized in this same section that

*the Sun's powerful Eddy currents are responsible for effecting the Sun's electromagnetic nodal rings, the gravitational force field (potential) wells encircling the Sun the planets and planetoid are embedded (trapped) in, which, when combined with the Sun's forces of these nodal ring gravitational wells, the planets and planetoids natural gravitational forces and their centrifugal forces, cause orbital stability to be maintained for all the orbiting bodies orbiting the Sun*

**.**This phenomenological scenario is described step-by-step in much more detail in the Second section of

**Part 1.**More astronomical history, followed by more celestial mechanics, is presented in

**Part 2.**

See **Part 3** and **4 Prefaces** for their contents**. **These** Parts **contains considerably more technical papers then **Parts 1** and **2.** For example, P**art 4 ** contains **WOODARD**'s paper on calculating orbits; and gives the essential pages from the book, ** Astronomical Paper..., Vol. XII, Coordinates of the Five Outer Planets, 1653-2060** (and the book's equations for the coordinates too)

On this day, 1/21/2019, added **HERGET**'s "* Computation of Orbits"* out-of-print textbook,

**Part I**, Chapters

**1**through

**5**; and

**Part II**(a separate document), Chapters

**6**through

**8**, plus some more references (contained in the

*section)*
