The Five Biggest Threats To Human Existence In the daily hubbub of current “crises” facing humanity, we forget about the many generations we hope are yet to come. Not those who will live 200 years from now, but 1,000 or 10,000 years from now. I use the word “hope” because we face risks, called existential risks, that threaten to wipe out humanity. Not everyone has ignored the long future though. But had these pioneers or futurologists not thought about humanity’s future, it would not have changed the outcome. We are in a more privileged position today. Future imperfect Yet, these risks remain understudied. If humanity becomes extinct, at the very least the loss is equivalent to the loss of all living individuals and the frustration of their goals. With that in mind, I have selected what I consider the five biggest threats to humanity’s existence. Finally, just because something is possible and potentially hazardous, doesn’t mean it is worth worrying about. 1. The Cuban Missile crisis was very close to turning nuclear. 2. 3. 4.

9 Economic Trends to Watch in 2014 Predicting trends is no easy task, especially in the short term. Most people who can do it accurately in the world of economics and finance are millionaires, or they should be. But if you don't have a crystal ball, at least you can watch some short-term trends with long-term implications. Here are nine of my favorites for the coming year -- and beyond. 1. Washington's strategic pivot to Asia seems to have fizzled -- but has the world's economic pivot as well? 2. The European Central Bank's top officials like to say that they have a symmetric target for inflation. 3. For decades, manufacturing employment in the United States has dropped as the productivity of manufacturing workers has increased. 4. As I've written before, wealth inequality is much more important than income inequality in determining access to opportunity. 5. Peak oil? 6. Remember Japan, the world's third-largest economy? 7. 8. 9. Allison Joyce/Getty Images
Reactionless motor: Needs more evidence. Photo by Paramount Pictures The ‘Net has been buzzing about a paper published by a team of engineers at NASA claiming that they have built a device that creates thrust without propellant. There have been lots of articles written about it, it’s spawned a zillion tweets, and I’m getting plenty of email asking me about it. Here’s the thing: I'm not convinced. I’m not saying it’s wrong, but I am saying it’s very, very likely to be some sort of measurement or experimental error. I could write a lot about this, but instead I’ll point you to two people who already have written excellent discussions on what’s going on here: John Baez on Google Plus (you should read both his first article and his second one) as well as my old friend Steve Novella. The bottom line here is what the team is proposing violates a very basic law of physics; all the forces inside the device appear to be balanced, yet a thrust is still generated. Photo by Brady et al., from the paper This device doesn’t have that yet.
5 Things Learners Expect From Their Educators (This is Part Two in a two-part series about the expectations of learning relationships. Please check our previous post in Part One: "5 Things Students Expect From Their Teachers.") More and more in recent years, we've started referring to the kids in our classes as "learners" rather than "students." It began unintentionally but became more and more frequent. A learner is someone who seeks knowledge, who solicits professional development, who values links from a Twitter PLN, or who watches YouTube videos to hone a skill. The word "learner" suggests an open-mindedness and a self-initiation. We’ve all experienced the letdown of learning, whether at disappointing conferences or half-hearted meetings. What do learners expect from their educators? Expertise Any learner who willingly admits that they do not know something is relying on the expertise of the person at the podium or the webcam. Clearly Delineated Goals Mentorship Hesitation and insecurity are natural byproducts of learning. Feedback

Hologram Projectors For Your Smartphone Could Be Close | IFLScience Just in time for the new Star Wars film, it seems the technology from the originals is starting to come true. First it was lightsabers, then prosthetic arms like Luke Skywalker's, and now we're being promised hologram projectors like R2D2 - although maybe not as cute. At the moment if you want to project three dimensional holograms into space you need to use mirrors or multiple sources placed around where the hologram is formed, so that light can interact from different directions. Ostendo Technologies, a California start-up are dreaming much smaller. However, the more ambitious goal, which Ostendo's founder Hussein El-Ghoroury hopes to achieve as soon as 2016, is to create three dimensional displays projected from a single phone. What Ostendo are not revealing is how they manage to project these images onto the air from a single direction.

Three Key Global Environmental Stories to Watch in 2014 Income growth across the developing world continues to spur individual empowerment, better health and longer lives, and environmental awareness. But it is also placing ever more pressure on natural resources as more people are able to afford energy-intensive and resource-depleting lifestyles, with bigger homes, more meat and fish in their diets, and private transportation. So, year after year, environmentalists inevitably find themselves asking the same question: “Can we continue growing the global economy while simultaneously making it more sustainable?” Each January during its annual forum, the World Resources Institute, an environmental and energy think tank in Washington, D.C., probes that question by examining key indicators across the globe. The list of trends to watch for in 2014, as outlined last week by Andrew Steer, the group’s president, reveals the most pressing environmental challenges as the world’s economy continues its ascent. How will cities grow and plan for the future?
Gecko-Inspired Climbing Paddles Allow A Man To Climb A Glass Wall | IFLScience We’ve heard a lot of stories recently describing awesome bio-inspired materials, from superhydrophobic surfaces to 3D printed shark skin. Now DARPA has gone and topped the biomimetics chart by showcasing their gecko-inspired climbing paddles that allow humans to climb vertical glass walls. The technology may be a little less glamorous than a spidey suit, but who cares, this is an amazing achievement. The devices form part of DARPA’s Z-Man program which aims to develop bio-inspired climbing equipment for use in warfare that will do away with conventional tools that have not advanced much over the years. The demonstration involved a 218-pound (99 kilogram) man using two hand-held paddles to ascend a 25 foot (7.5 meter) glass wall, without needing a safety belay. And just to show off, they conducted another trial where the man was carrying a further 50 pounds of weight (22.5 kg). DARPA scientists had two main hurdles to overcome whilst attempting to mimic the gecko toe.
L'innovation pédagogique en 10 points Depuis 2012, l'Open University britannique publie à l'automne un rapport sur les plus fortes tendances de l'innovation pédagogique repérées au cours de l'année. La publication est fort attendue, compte-tenu de l'autorité dont jouit l'Open U dans le domaine des technologies pour l'enseignement et l'apprentissage, et de son rôle dans de nombreux projets liés aux sciences de l'éducation. Le rapport dans sa version la plus récente consacre dix tendances et dispositifs éducatifs / d'apprentissage, à l'impact potentiel plus ou moins fort, à brève ou moyenne échéance. Les dix innovations pédagogiques de l'année 2013 1- Les MOOCs. 2- Les badges. 3- Les données d'apprentissage (Learning analytics). 4- L'apprentissage unifié (Seamless learning). 5- L'apprentissage par la foule (Crowd learning). 6- L'activité académique numérique (Digital scholarship). Les quatre tendances suivantes juissent d'un potentiel "disruptif" moins fort, ou à plus long terme : 8- Apprendre du jeu (Learning from gaming).
PDI > Continuing Education > PDI Blog > Identifying the Black Swan – Can You Spot the Risk A “black swan event” is defined as one that is a surprise to the observer, has a major effect, and following its first occurrence, is rationalized by hindsight as if it could or should have been expected or predicted. Could the “unexpected” actually have been foreseen? How often have we been caught off guard by the “unexpected” that was right in front of us? We often find ourselves focused on one particular area of risk leading us to inevitably miss it in unexpected areas like partner relationships, individual behaviour or strategy that together influence one’s overall corporate reputation. The Ripple Effect: How the small things become huge Is it all really damage worthy? · Take the example of a manufacturing organization that minimizes the legitimacy, impact and influence of a grassroots stakeholder movement that manages to gain momentum, locally and globally, resulting in the disruption of production and delivery volumes or derailing a contract negotiation. · anticipate, · identify,
