Introduction Word length and phrase length influence the ease of reading and understanding of a given text. Short words are usually more common (Zipf's law). Short sentences require less abstraction ability to understand. The readability analysis could be useful to make a text better, augmenting its accessibility. Why have we developed this? The readability index tells us how easy a given text is to understand. A well-written text is effective, easy to understand and quick to read. This index helps us understand the text's complexity in order to better schedule the activities of translators and revisers. More than ever, written information, especially in the Internet, must be direct and well structured. This analysis can help achieve both goals.

HP has just unveiled an incredibly ambitious project to create a “Central Nervous System for the Earth” (CeNSE) composed of billions of super sensitive, cheap, and tough sensors. The project involves distributing these sensors throughout the world and using them to gather data that could be used to detect everything from infrastructure collapse to environmental pollutants to climate change and impending earthquakes. From there, the “Internet of Things” and smarter cities are right around the corner.HP is currently developing its first sensor to be deployed, which is an accelerometer 1,000 times more sensitive than those used in the Wii or the iPhone – it’s capable of detecting motion and vibrations as subtle as a heartbeat. The company also has plans to use nanomaterials to create chemical and biological sensors that are 100 million times more sensitive than current models. Their overall goal is to use advances in sensitivity and nanotech to shrink the size of these devices so that they are small enough to clip onto a mobile telephone.Once HP has created an array of sensors, the next step is distributing them and making sense of all the data they generate. That’s no easy task, granted that a network of one million sensors running 24 hours a day would create 20 petabytes of data in just six months. HP is taking all that number crunching to task however, and will be harnessing its in-house networking expertise, consulting, and data storage technologies for the project.The creation of a global sensor system would be an incredible breakthrough – it could make our cities more efficient, save lives, and enable us to better understand, track, and combat climate change. As HP Labs senior researcher Peter Hartwell has stated, “If we’re going to save the planet, we’ve got to monitor it“.+ CeNSEVia Fast CompanyLead photo by Margie Wylie Comments RSS Comments RSS digg_url = 'http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/'; digg_title = 'HP Invents a Central Nervous System for the Earth'; digg_skin = 'compact'; email this tweetmeme_url = "http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/"; tweetmeme_style = "compact"; facebook this Related Posts

Moreover—and perhaps most damning—by blocking and banning many of the tools and Web sites that form the cornerstone of teenagers’ experiences, educators deny themselves access to the conversations that students are having about how to use these tools intelligently, ethically, and well. And given the overwhelming flow of information that students can access using such tools, it is essential that educators become part of those conversations.

Districts have spent thousands of dollars installing interactive whiteboards—which are a more powerful, more engaging chalkboard. And yes, they are a tool with some very useful functions, and yes, we have them at the Science Leadership Academy in Philadelphia, where I am principal. But let me be clear: interactive whiteboards only enable a teacher-centric style of teaching to be more engaging than it would have been with a traditional chalkboard. Much of the prepackaged educational gaming similarly makes the same mistake.

The single greatest challenge schools face is helping students make sense of the world today. Schools have gone from information scarcity to information overload. This is why classes must be inquiry driven. Merely providing content is not enough, nor is it enough to simply present students with a problem to solve. Schools must create ways for students to come together as a community to ask powerful questions and dare them to bring all of their talents to bear on real-world problems.
