"The Fairphone is a modular handset designed with repairability and ethical sourcing of its materials as headline features. It sold 60,000 units. Amazingly, for what sounds like a nerd-phone, almost half of those buyers had never owned a smartphone before. Now the Fairphone 2 is launching, and with a totally-new, in-house design. The new phone is even easier to repair, and because it was wholly designed by the FairPhone team, its supply chain is even more responsible than ever. The Fairphone is thicker than the latest iPhone or Samsung flagship, but that's the point. Instead of packing everything into a tiny case and keeping it there with glue, the Fairphone is designed to be taken apart. The lightweight magnesium frame supports modules that can be easily replaced by the user. "We have designed it with an aim to last three to five years, looking at making it robust and modular-for repairability," says Fairphone's chief communications officer, Tessa Wernink. "Obviously how long it lasts depends quite heavily on the user, so what we as a company are doing is offering an ecosystem around the phone that supports long-lasting use, first-hand or second-hand." Inside the case (itself one of several options) you'll find the core unit, containing all the chips and radios; a replaceable battery pack; a display that can be snapped off and replaced without any tools (not even a screwdriver); a receiver unit, which contains the front camera, sensors; the headset connector and microphones; a speaker/vibrator unit; and a camera module. These modules are designed to balance manufacturing complexity with repairability. For instance, the display comes as a standalone unit, but less-vulnerable components are bundled into one module. The camera, which people are most likely to upgrade as better versions become available, is also housed in its own module. That way you don't need to toss out your whole phone just to get a better camera. "In fact, the motto from the maker mo

"Today, getting what you need is as easy as a trip to the store. From food to clothing, energy, medicine, and so much more, Andy George will discover what it takes to make everything from scratch. His mission is to understand the complex processes of manufacturing that is often taken for granted and do it all himself. Each week he's traveling the world to bypass the modern supply chain in order to harvest raw materials straight from the source. Along the way, he's answering the questions you never thought to ask."

"Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

"Open with a question or two. Another favorite education writer of mine, the cognitive psychologist Daniel Willingham, argues that teachers should focus more on the use of questions. "The material I want students to learn," he writes in his book Why Don't Students Like School?, "is actually the answer to a question. On its own, the answer is almost never interesting. But if you know the question, the answer may be quite interesting." My colleague Greg Weiner, an associate professor of political science, puts those ideas into practice. At the beginning of class, he shows four or five questions on a slide for students to consider. Class then proceeds in the usual fashion. At the end, he returns to the questions so that students can both see some potential answers and understand that they have learned something that day. What did we learn last time? A favorite activity of many instructors is to spend a few minutes at the opening of class reviewing what happened in the previous session. That makes perfect sense, and is supported by the idea that we don't learn from single exposure to material - we need to return frequently to whatever we are attempting to master.But instead of offering a capsule review to students, why not ask them to offer one back to you?Reactivate what they learned in previous courses. Plenty of excellent evidence suggests that whatever knowledge students bring into a course has a major influence on what they take away from it. So a sure-fire technique to improve student learning is to begin class by revisiting, not just what they learned in the previous session, but what they already knew about the subject matter.Write it down. All three of the previous activities would benefit from having students spend a few minutes writing down their responses. That way, every student has the opportunity to answer the question, practice memory retrieval from the previous session, or surface their prior knowledge - and not just the students most likely to

Primitive technology is a hobby where you make things in the wild completely from scratch using no modern tools or materials. This is the strict rule. If you want a fire- use fire sticks, an axe- pick up a stone and shape it, a hut- build one from trees, mud, rocks etc. The challenge is seeing how far you can go without modern technology. If this hobby interests you then this blog might be what you are looking for. Also It should be noted that I don't live in the wild but just practice this as a hobby. I live in a modern house and eat modern food. I just like to see how people in ancient times built and made things. It is a good hobby that keeps you fit and doesn't cost anything apart from time and effort.

"Striking evidence has emerged that an ancient virus previously known only from fossil evidence has persistently infected some humans at very low levels for hundreds of thousands or even millions of years. This ancient retrovirus is a kind of living fossil, and the discovery of an intact copy of it within the human genome poses questions as to how it has survived, and suggests others from the distant evolutionary past may lie dormant in the DNA of many species. ..."

"there is no live teacher engagement... Currently, just 10 percent of MOOC registrants complete their courses. Where Will MOOCs Be Just Two Years From Now? Within the next two years, MOOCs will quickly evolve from lacking teacher engagement to having a lot of teacher engagement. Right now, it's essentially a model where computers are teaching students. This model is simply not sustainable in the long run without live student-teacher engagement. Teachers are the key that unlocks learning in these courses. They help students resolve issues and problems. Will the biggest change in online education moving forward be putting live teachers at the center of the MOOC (not just on video)? We will know the answer very soon."

"A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth's climate past a disastrous tipping point in as little as a century. On a 1987 voyage to the Antarctic, the paleoceanographer James Kennett and his crew dropped anchor in the Weddell Sea, drilled into the seabed, and extracted a vertical cylinder of sediment. In an inch-thick layer of plankton fossils and other detritus buried more than 500 feet deep, they found a disturbing clue about the planet's past that could spell disaster for the future. Lower in the sediment core, fossils abounded from 60 plankton species. But in that thin cross-section from about 56 million years ago, the number of species dropped to 17. And the planktons' oxygen and carbon isotope compositions had dramatically changed. Kennett and his student Lowell Stott deduced from the anomalous isotopes that carbon dioxide had flooded the air, causing the ocean to rapidly acidify and heat up, in a process similar to what we are seeing today."

"This is not an environmental book, even though it is concerned with the environment. It is not a book to save the world, even though the world is clearly in trouble. Ultimately, A Matter Of Scale is a book about survival; about ensuring that every individual human has the means to save herself or himself from the crisis that is unfolding. And there most certainly is a crisis; like the waves of a surging river; small and irregular at first, but growing larger, creating whirlpools, rising in treacherous white water, and eventually inundating everything in its path. People know that the climate is changing, that species are being removed from the Earth at a rapidly increasing rate, that entire ecosystems are becoming shadows of their former richness; they know, but they do not understand. The environmental crisis is closing in on humanity from all directions, yet the crisis barely registers on this culture's list of problems. As we stand, humanity is doomed to a collapse that will leave only a few nomads, and a toxic, barely survivable Earth in its wake."

"The Minute Paper comes in many variations, but the simplest one involves wrapping up the formal class period a few minutes early and posing two questions to your students: What was the most important thing you learned today? What question still remains in your mind? Taken together, those two questions accomplish multiple objectives. The first one not only requires students to remember something from class and articulate it in their own words (more about that in a moment), but it also requires them to do some quick thinking. They have to reflect on the material and make a judgment about the main point of that day's class. The second question encourages them to probe their own minds and consider what they haven't truly understood. Most of us are infected by what learning theorists sometimes call "illusions of fluency," which means that we believe we have obtained mastery over something when we truly have not. To answer the second question, students have to decide where confusion or weaknesses remain in their own comprehension of the day's material. Closing connections. If we want students to obtain mastery and expertise in our subjects, they need to be capable of making their own connections between what they are learning and the world around them - current events, campus debates, personal experiences. The last five minutes of class represent an ideal opportunity for students to use the course material from that day and brainstorm some new connections.The metacognitive five. We have increasing evidence from the learning sciences that students engage in poor study strategies. Likewise, research shows that most people are plagued by the illusions of fluency. The solution on both fronts is better metacognition - that is, a clearer understanding of our own learning. What if all of us worked together deliberately to achieve that?Close the loop. Finally, go back to any of the strategies I introduced in my recent column on the first five minutes of clas

"Evaporative coolers have been known to purveyors of low-cost, sustainable technologies for years. Without the need for electricity, these cold containers have kept produce fresh from farms to tables, protecting against post-harvest losses in the field and food spoilage in hot pantries worldwide. Now the concept has been applied to air conditioning. Manoj Patel Design Studio in Vadodara, Gujarat (India) has built evaporative air conditioners that can cool a room for days on a single tank of water. The studio designs new products from recycled materials, and they built their air conditioners from ceramics and stone, integrating them with potted plants. By filling rows of ceramic tubes with water, the prototypes maximize their surface area for optimal evaporation while retaining a small footprint. ..."

"What does that mean exactly? It means you play in a multiplayer world that has the possibility of being permanently destroyed, resulting in server-wide perma death. What's more, the reason it's destroyed would be the players' own fault. It's not that different from our own world in that way. "This ecosystem is your only lifeline in a race against time." It works like this: a new server is started, and players enter at the beginnings of civilization. There's a world-destroying cataclysm looming, like a drought or a flood or a meteor heading for the Earth, several real-time weeks away. In order to prevent that catastrophe from happening, you need to build a civilization and advance technology and resources to the point that the crisis can be averted. However you're not alone in this world. Besides the other players, you'll be sharing the world with a detailed wilderness simulation full of plants and animals. They simulate 24 hours a day, living out their lives with or without human interaction, growing, feeding and reproducing. Together they form an ecosystem rich with resources, resources that you must use to survive and develop a civilization."
