BookofProofs (BoP) is an open web catalog dedicated to mathematics, physics or computer science, which is completely run by the Internet community. Every catalog entry is thoroughly reviewed to ensure high quality and avoid redundance. The goal of the project is to make this catalog as comprehensive as possible, while providing it for free and for educational purposes to the public.
Unlike in Wikipedia, the entries in this catalog do not have to be of encyclopedic significance with verifiable sources to be accepted. The verifiability with reliable sources is welcomed but not required, because it is up to the Intenet community to improve the reliability of this catalog. This means that, as a registered user, you can publish here your original educational or research material, if it is related to mathematics, physics or computer science, you hold the copyright and you agree to the licence terms valid for this site.
In the "Branches" module, the catalog entries are not selfcontained articles or mathematical papers, but rather single mathematical definitions, theorems, examples, problems (e.g. exercises), their solutions, and, of course, mathematical proofs. In the "History" module, the entries contain either biographies of mathematicians or historical events with importance for the mathematical research. The growing library of BoP currently consists of 4148 entries, contributed since 1 May 2014 (going life of the project) by 16 author(s).

BoP meets Python!
We decided to replace the original pseudo code algorithm engine by Python syntax highlighting. Python is a great, powerful and easytolearn programming language and comes out with thousands of free libraries. Now you can share your awesome Python algorithms under the CCBYSA license.

BoP goes interactive!
Bring mathematics to life and enjoy our documents containing interactive demonstrations on devices running iOS, Android, firefoxOS, Windows 8 (at least).
If you are a BoP author (or want to become one), its now very easy to embed your or other people's own mathles into your articles, based on JSXGraph (project of the University of Bayreuth, Germany).

A stepbystep introduction for adding your content provided
Adding or editing content of BookOfProofs is very easy, but slightly different from blogs or other wikis you might find on the Internet. Learn in a short stepbystep introduction how.

BookOfProofs introduces an experimental visualization of the axiomatic method.
Proofs are the strength of mathematics and the axiomatic method is what makes them so powerful  based on simple
axioms and using logical reasoning one proves theorems, and based on these theorems one proves even more theorems, and so forth  like a snow ball.
BookOfProofs introduces a visualization of this principle by attaching clickable graphics to each axiom, definition and theorem (learn more in "The Axiomatic Approach on BookofProofs").
These structures are dynamic. This means that adding a hyperlink to a proof of a theorem A, which refers to a theorem B, will be visualized by showing that the theorem B logically proceeds the theorem A.
This logical chain can be followed backward to simple axioms and definitions or forward to more and more deep theoretical results.

Going life.
The site's mission statement is to be an open community project to create a cartography of existing mathematical
results ("what follows from what?"). The site aims to bring the mathematical ways of approaching and solving problems
to a broader public.
It contains a first draft topdown table of contents of mathematical topics, which can also be used for easy navigating the site.
Some of the topics contain first definitions, theorems, proofs and examples.
All interested visitors are kindly invited to contribute to the project.
