Future - Science & Environment - Drake equation: How many alien civilizations exist? Are we alone? It is a question that has occupied mankind for centuries. Today, we live in an age of exploration, where robots on Mars and planet-hunting telescopes are beginning to allow us to edge closer to an answer. While we wait to establish contact, one technique we can use back on Earth is an equation that American astronomer Frank Drake formulated in the 1960s to calculate the number of detectable extraterrestrial civilizations may exist in the Milky Way galaxy.

Information visualization Graphic representation of a minute fraction of the WWW, demonstrating hyperlinks Information visualization or information visualisation is the study of (interactive) visual representations of abstract data to reinforce human cognition. The abstract data include both numerical and non-numerical data, such as text and geographic information. However, information visualization differs from scientific visualization: "it’s infovis [information visualization] when the spatial representation is chosen, and it’s scivis [scientific visualization] when the spatial representation is given". Overview
20 Years Since The Fall of the Soviet Union - Alan Taylor - In Focus My friend Alain-Pierre Hovasse is a photojournalist who was based in Moscow in August of 1991, and was a firsthand witness to many of the historic events - six of the photos above were taken by him. I asked if he'd be interested in sharing some observations from that time, happily he agreed and has shared his memories here: In 1991, I was hired away from Reuters in London to be Chief Photographer for the Agence France Presse and the European Press Agency in Moscow. It was perestroika (restructuring) under Gorbachev's tenure in the USSR; changes had been taking place since the collapse of the Berlin Wall and other Soviet satellites in 1989, and AFP had until then no permanent photographer in Moscow.

Normally, I stay away from assumptions: We all know the saying about what assuming does to you and me! When it comes to managing or building communities, online or on the ground, the work can seem overwhelming and sometimes even never-ending. Diagram A diagram is a two-dimensional geometric symbolic representation of information according to some visualization technique. Sometimes, the technique uses a three-dimensional visualization which is then projected onto the two-dimensional surface. The word graph is sometimes used as a synonym for diagram. Overview The term diagram in common sense can have a general or specific meaning:
untitled Art of Conversation – article edition Keith May 9th, 2011 Further to previous posts here on the transformative power of conversation – the Ignite presentation at KMLF, and the trampoline presentation - I have now also written an article on the topic, which was published by Thomson-Reuters’ Online Currents last month. This article has documented in a little more detail the recent research that highlights how conversation can actually make us smarter and more innovative – this research is from: Anita Williams Woolley et al, who found that “small groups demonstrate distinctive ‘collective intelligence’ when facing difficult tasks”.Steven Johnson’s book Where Good Ideas Come From, on cultural progress and how innovation really works.Oscar Ybarra et al, showing that even brief, friendly conversations can improve individual mental function. This research is summarised and drawn together in the article, along with other thoughts on conversation, change and social media.
Graph (mathematics) The edges may be directed or undirected. For example, if the vertices represent people at a party, and there is an edge between two people if they shake hands, then this is an undirected graph, because if person A shook hands with person B, then person B also shook hands with person A. In contrast, if there is an edge from person A to person B when person A knows of person B, then this graph is directed, because knowledge of someone is not necessarily a symmetric relation (that is, one person knowing another person does not necessarily imply the reverse; for example, many fans may know of a celebrity, but the celebrity is unlikely to know of all their fans). This latter type of graph is called a directed graph and the edges are called directed edges or arcs. Vertices are also called nodes or points, and edges are also called arcs or lines. Graphs are the basic subject studied by graph theory.
The Elements by Theodore Gray My book The Elements is based on photographs I've been collecting at my website periodictable.com for many years. The website includes not just pictures, but also more detailed descriptions than we could fit in the book, and most importantly, it includes full 360-degree rotating videos of almost all the objects. You really won't find this kind of resources anywhere else for any other subject, so please enjoy. If you don't have the book yet, please don't think this is page is a substitute for the real thing. Aside from the fact that people buying the book (and my other photo periodic table products) is what pays for me being able to continue hosting the website, there's really no substitute for a paper book in your hands. The book also makes a fabulous gift, and you can't give a website as a gift!
untitled Presentation – The Idea Monopoly? Keith June 25th, 2010 “Nearly 60 percent of projects aimed at achieving business change do not fully meet their objectives.” – IBM, 2008. Why does this happen? As many working in Knowledge Management and related fields understand, it’s all about people and complexity. Flowchart A simple flowchart representing a process for dealing with a non-functioning lamp. A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields. Overview Flowcharts are used in designing and documenting complex processes or programs.
