**PlanetPhysics** is a virtual community ^{[1] }^{[2]} with Several websites ^{[3]} supported by a non-profit organization registered in the USA ^{[4]} in an open science , open data , peer-to-peer review method ^{[5] }^{[6] }^{[7] }^{[8] }^{[9] }^{[10] }^{[11] }^{[12] }^{[13] }^{[14]} as well as physically and related mathematics , Logical, computational and mathematical physics concepts.^{[15] }^{[16] }^{[17] }^{[18] }^{[19] }^{[20]}

PlanetPhysics est aussi a free , collaborative, online physics , mathematical physics , ^{[21]} computational physics and physical mathematics project, including original articles, lectures, books and encyclopedia entries. The emphasis is is openness, pedagogy , content real-time, Harsh, interlinked happy and aussi based was virtual community , or virtual group, of about 600 people with various physics, mathematical physics, physical mathematics, logic (Such As quantum logic , Relational logic and many-valued logics), axiomatics and mathematics interests.

## Content

The main PlanetPhysics.org focus is on both original research and encyclopedic entries; With over 3,400 physics and mathematics concepts edited in LaTeX and rendered in HTML , the PlanetPhysics Encyclopedia is at present the largest physics encyclopedia written in LaTeX, containing both introductory and advanced level presentations. Moreover, its sections on papers and exhibitions, are second only to CERN and arXiv physics preprint archives.

In addition, the PlanetPhysics.org new websites also include extensive graphics illustrations of physics experiments, and also forum discussions. The emphasis is on modern physics, including advanced physics and mathematical physics concepts.

The project hosts data containing physics, applied physics, engineering and mathematics books, readings, preprints and research-level papers. A system for both private and semi-private messaging among users is also in place.

As of 15 May 2012 , the Physics and Mathematical Physics projects hosted over 2,000 entries, containing more than 30,000 *concepts* in books, readings, exhibitions, encyclopedia entries, and papers. Several Wikipedia entries also incorporate text from PlanetPhysics articles, and *vice versa* , several PlanetPhysics articles contain links or refer to Wikipedia entries.

### Content development models

PlanetPhysics implements several specific content creation systems based on the *Noosphere versions 1.0 / 1.5* , *Planetary* (powered by Drupal ), and MediaWiki currently being updated to allow peer-to-peer review, as well as preprints and encyclopedic contributions. This is different from the so-called *authority model* previously adopted by PlanetMath . ^{[22]} Only registered users can create and edit their own entries, or contribute jointly, by agreement, to various topical entries. The MediaWiki *version 1.17* is the most widely used version of PlanetPhysics for creating books, uploading PDF files of open access articles, And also for graphics-intensive physics. ^{[23]}

An author who publishes a new article with *Noosphere version 1.5* (created by Aaron Krowne) retains intellectual property ownership of which entry, and is the only person authorized to edit this article. Selected by the author. Other users may, however, add corrections and discuss improvements that must be approved by the original author. When there are long lasting (> 30 days) unresolved necessary corrections, either the ownership or the entry could be removed by the web site administration.

A major strength of the *Noosphere* versions 1.0 and 1.5 *planetphysics.us* website is icts capability of linking in real time conceptually related entries, as well as automatically list all the concepts defined by the Article Either or related to the item in the Physics and Mathematical Physics encyclopedia. Any PlanetPhysics contributor can also explicitly create links to other articles, and the Noosphere 1.0 system also automatically turns certain words into links to the defining articles. The topic area of every item is classified by Either the Physics and Astronomy Classification Scheme (PACS) or the Mathematics Subject Classification (MSC).
