"This morning I visited TED-Ed's Lesson catalog and saw a new lesson about the pancreas. Seeing that video prompted me to look for other TED-Ed videos about the human body. I came up with four more and put them into a little playlist on YouTube. The five videos cover the pancreas, kidneys, lungs, heart, and liver. The playlist is embedded below."

"Libraries have existed since approximately 2600 BCE as an archive of recorded knowledge. From tablets and scrolls to bound books, they have cataloged resources and served as a locus of knowledge. Today, with the digitization of content and the ubiquity of the internet, information is no longer confined to printed materials accessible only in a single, physical location. Consider this: Project Gutenberg and its affiliates make over 100,000 public domain works available digitally, and Google has scanned over 30 million books through its library project. Libraries are reinventing themselves as content becomes more accessible online and their role becomes less about housing tomes and more about connecting learners and constructing knowledge. Cushing Academy in Ashburnham, Massachusetts has been in the vanguard of this transition since 2009, when it announced its plans for a "bookless" library. A database of millions of digital resources superseded their 20,000-volume collection of books, and a café replaced the circulation desk. With this transition, not only did the way in which students consumed content change, but also how they utilized the library space. Rather than maintain a quiet location for individual study, the school wanted to create an environment for "collaboration and knowledge co-construction.""

"With so many Raspberry Pi projects to choose from, it can be tricky to find the one you really want to build. Our advice is to find a way to marry the Pi with something you really love. One great example is TV and movie robots - iconic characters from popular sci-fi that can be rebuild at home with a Raspberry Pi built in. Once constructed, your robot might be able to utter commands when a condition is met (perhaps a sensor detects motion). Or it might move around, learning about its surroundings, or reading information to you from Wikipedia. Whatever you have in mind, it should be relatively straightforward to plan and execute. It may take some time, however. Here are five example projects that show how you can combine a Raspberry Pi 2 or later with your favorite fictional robot. 5 Things Only a Raspberry Pi 2 Can Do 5 Things Only a Raspberry Pi 2 Can Do The latest edition of the pint-sized computer is awesome. So awesome, in fact, that there's 5 things you can only do on a Raspberry Pi 2. READ MORE 1. R2-D2 We've all wanted our very own astromech droid, haven't we? Sure, no one on earth is (currently) operating a light speed drive, but Star Wars droid R2-D2 has far greater abilities than onboard spacecraft maintenance. For instance, he can hold torches, carry a tray of drinks, and launch lightsabers across pits in the desert. Okay, it's unlikely you'll manage to get your own R2-D2 robot to do that… but don't let that put you off. Check out this little guy, controlled by a Raspberry Pi. While this project was based on an existing R2-D2 toy, that shouldn't limit your ambition. You'll find plenty of R2-D2 builds on YouTube. There's a massive R2-D2 building community online. Finding one that has a drive unit should be ideal for integrating a Raspberry Pi (and perhaps an Arduino, which you can use the two together) and developing a more realistic R2-D2 experience. Arduino vs Raspberry Pi: Which Is The Mini Computer For You? Arduino vs Rasp

"If you own an e-reader you often can only buy e-books from the bookstore that is bundled on your device. Many of the budget e-readers out there don't even have a bookstore that is accessible by users and many people are left to fend for themselves to load content on it. Today we are proud to give you the most comprehensive free e-book resource catalog online. All of these books are hardware agnostic, which means they are not locked by DRM (Digital Rights Management). All you have to do is simply download a title and load in via the USB cable from your computer to your e-reader. Many of these sites also provide the books in more than one format, so they will work with your Amazon Kindle, Kobo, Barnes and Noble Nook, Sony e-reader and hundreds of others."

Mind officially blown! I love these maths manipulative apps for iOS and here they are as a web app. This just made my day!
