Taking Randall Munroe’s excellent Radiation Dose Chart and a Japanese-language version of the same as our data sources, we have visualised radiation doses as spheres (the shaded orange disc above). Each sphere has a volume that is directly proportional to the radiation dose it depicts (1µSv ≈ 16.14cm3). The spheres are shown next to a human figure, adding a human dimension to the comparison while also establishing the scale of each view (we have assumed a height of the figure of 175cm, which is fairly average for an adult male).

Here are the graphs depicting the evolution of the main parameters of Fukushima NPP1 reactors (unit1 to unit3) since the accident. . Data is taken directly from NISA’s press releases, and can also be retrieved on the following online Excel workbook. The later will always have the latest data, but I’ll add periodic snapshots to this post for those that can’t view it.

Every educated person really ought to have a basic understanding of accounting. Just like maths, science, programming, music, literature, history, etc., it’s one of those things which helps you make sense of the world. Although dealing with money is not much fun, it’s an unavoidable part of life, so you might as well take a few minutes to understand it.

Eventually I figured it out: basic accounting is just graph theory. The traditional ways of representing financial information hide that structure astonishingly well, but once I had figured out that it was just a graph, it suddenly all made sense.

This map has been created by compiling reports from trusted accounts on Twitter. Nonetheless, these reports are in general unconfirmed. This information should be considered in the context of there being absolutely no independent media in Libya at this time. This map is not automatically produced. Each posting is considered before it is mapped. These considerations have evolved over time as conditions on the ground have changed.

pv - Pipe Viewer - is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.

This scientific visualization creates a three-dimensional virtual tour of several dark pillars of cool gas in the Carina Nebula. The stars and nebula layers from Hubble's two-dimensional image have been separated using both scientific knowledge and artistic license to create the depth in the movie. Of note, the relative distances between stars and the nebula have been greatly compressed. The result is an intriguing journey through a virtual cosmic landscape.

This version of the movie is presented in anaglyph stereo 3D and is viewable with glasses that have a red lens over the left eye and a cyan (a.k.a. blue-green) lens over the right eye. Such glasses are often made of cardboard and have been distributed in numerous 3-D promotions. An internet search for "red cyan anaglyph glasses" will provide many options for obtaining such glasses.

Graphical process explorer for Linux. Shows process information: process tree, TCP IP connections and graphical performance figures for processes. Aims to mimic Windows procexp from sysinternals, and aims to be more usable than top and ps.
