The United Kingdom is one of eight, probably nine nuclear powers. (Israel has never confirmed that it has tested/operates nuclear weapons.) Unlike most countries, the UK only uses one delivery system to operate its weapons: submarines using Trident ballistic missiles.
The British Trident system became an issue in the coalition government. While it was supported by both the previous Labour government and the Conservatives, the programme had to be reviewed per the coalition agreement. The review has been completed and it will be made public. But to explain to the public how Trident works, the BBC created this graphic. It does a really good job of showing the reach of the British submarines from one location, but then showing why an adequate replacement would need at least three to four submarines.

Today’s post comes from xkcd. It looks at how much time can be spent improving efficiency before you become an inefficient efficiency person. It is important to note that this is over a five year span. And while I do not know about my readers, I can barely stick doing one thing for more than a year.
The Brookings Institution released a report investigating the ridership of Amtrak’s various routes in an attempt to identify ways of cutting costs. They also released an interactive piece along with the report that pairs a map with a simple table.
Highlighting a route in the table highlights the route in the map and links the two together for the user. Clicking a dot on the map shows the details for the metropolitan area ridership along with the total number of stations. Lastly, because the table is sortable, the user can identify for themselves the conclusion reached by the report. To become solvent, Amtrak should divest itself of its long-haul routes that run at significant losses and focus on the profitable routes that could subsidise the popular though still minor loss-making routes.
Japan continues to deal with damage from the earthquake and its subsequent tsunami. Yet, much of the news that seems to come out of Japan focuses on the leak of radioactive materials from the Fukushima power station. Certainly that is a story, but is it more important than the tens of thousands of people missing and presumably dead?
The New York Times printed a graphic on Saturday that details the danger from the radiation at the plant, near the plant, across Japan, and then across the rest of the world.
And largely, if you live in the United States, you have no reason to fear the radiation leak. In general, unless you maybe live near the plant, you have no reason to fear the radiation leak.
Overall, it communicates its message clearly and adds nice detail in the bottom third of the graphic about whatever spread of radiation there has been.
