Phosphorus: Wikipedia Visual Summary by WikiSummarizer

Visual presentation communicates information clearly and effectively through graphical means. WikiSummarizer is a Web-based application that summarizes Wikipedia articles and presents them as Visual Summaries, Tree Views and Keyword Clouds with links to Wikipedia Knowledge Base.

WikiSummarizer is an interactive learning and teaching tool providing effective graphical visualization that reduces complex information and provides clear and attractive presentation of the essential points. The interactive summaries are easily shared and published in blogs, websites and documents as digital Visual Summaries, Tree Views and Keyword Clouds.

It is easy to collaborate and mine information using the WikiSummarizer summaries in blogs, websites, word editors, browsers, mind mapping applications, databases and content management systems.

This Visual Summary presents the keywords and the summaries of the Wikipedia article about "Phosphorus". The Visual Summary map and the Keyword Cloud were automatically created by WikiSummarizer.

Essential Summary

 

Wikipedia article:  Phosphorus

 

Phosphorus

 

Phosphorus (100)

 

·         A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate rocks.

 

·         Elemental phosphorus exists in two major forms—white phosphorus and red phosphorus—but due to its high reactivity, phosphorus is never found as a free element on Earth.

 

·         The first form of elemental phosphorus to be produced (white phosphorus, in 1669) emits a faint glow upon exposure to oxygen – hence its name given from Greek mythology, Φωσφόρος meaning "light-bearer" (Latin Lucifer), referring to the "Morning Star", the planet Venus.

 

·         Although the term "phosphorescence", meaning glow after illumination, derives from this property of phosphorus, the glow of phosphorus originates from oxidation of the white (but not red) phosphorus and should be called chemiluminescence.

 

·         The vast majority of phosphorus compounds are consumed as fertilizers.

 

·         Today, the most important commercial use of phosphorus-based chemicals is the production of fertilizers, to replace the phosphorus that plants remove from the soil.

 

·         The two most common allotropes are white phosphorus and red phosphorus.

 

·         White phosphorus and related molecular forms The most important form of elemental phosphorus from the perspective of applications and chemical literature is white phosphorus.

 

·         In this sense, red phosphorus is not an allotrope, but rather an intermediate phase between the white and violet phosphorus, and most of its properties have a range of values.

 

·         Phosphorus is not found free in nature, but it is widely distributed in many minerals, mainly phosphates.

 

·         The white phosphorus is then oxidised to phosphoric acid and subsequently neutralised with base to give phosphate salts.

 

·         Oxides The most prevalent compounds of phosphorus are derivatives of phosphate (PO4), a tetrahedral anion.

 

·         In 1769 Johan Gottlieb Gahn and Carl Wilhelm Scheele showed that calcium phosphate (Ca3(PO4)2) is found in bones, and they obtained phosphorus from bone ash.

About Context Discovery WikiSummarizer

WikiSummarizer is a Web-based summarization portal that summarizes Wikipedia articles and presents the results as a structured outline, a Visual Summary and a Keyword Cloud.

The Visual Summary can be navigated in any browser on Windows, Mac, Linux, iPhone, iPad and Android devices.

The Keyword Cloud is linked with Wikipedia Knowledge Base. When you click on the keyword in the cloud you will be presented with an instant Visual Summary.

The keywords and summaries are easily exported to other applications such as word editors, browsers, mind mapping applications like Mindjet MindManager, MindGenius, XMind, and any other mind mapping application.

The summaries are stored in a knowledge library.

Report writers can be easily used for knowledge mining of the summaries, keywords and links. The Wikipedia Knowledge Base search function works as a back-of-the-book index pointing to the most relevant summaries and links.

About Henry

Hi, I’m Henry Lewkowicz and I’m the CEO of Context Discovery Inc. For long time I have been interested in the importance of context in understanding information. Intuitively we recognize the meaning of context when we say “you took my words out of context”. This phrase vividly signifies how much we care about our intentions and point of view. I believe that in the Internet age context plays a big role in rapid understanding of information. I’ll go on the record and say that in fact seeing information in context dramatically speeds understanding and simplifies application of information. In this blog I hope to have a lively dialog with you on a range of subjects related to context, information overload, knowledge, learning and other fun topics. In the course of doing it I will be using our own application, Context Organizer, as an experiment in capturing in 1 sentence what bloggers and other writers publish. I hope that we all will have some fun with it and learn more about communicating. Although this is primarily a technology and business blog, to great degree it's also my personal blog. From time to time, amongst the customary posts, I will write about issues that I passionately care about, my travels, and photos that I've taken. Periodically I refer to my family or friends, and sometimes you even see my vacation photos. I hope to make lots of new friends and learn a great deal in the process. Life is too short…. Enjoy, and feel free to write to me.
