If humans were ever able to get their hands on just one asteroid, it would be a game-changer. That’s because the value of many asteroids are measured in the quintillions of dollars, which makes the market for Earth’s annual production of raw metals – about $660 billion per year – look paltry in comparison. The reality is that the Earth’s crust is saddled with uneconomic materials, while certain types of asteroids are almost pure metal. X-type asteroids, for example, are thought to be the remnants of large asteroids that were pulverized in collisions in which their dense, metallic cores got separated from the mantle. There is one such X-type asteroid near earth that is believed to hold more platinum than ever mined in human history. Near-Earth Mining Targets Both companies are looking specifically at near-Earth asteroids in the near-term, which are the easiest ones to get to. Where the Money is Made
Primary Website | Alberto Cairo Anonimowy posiadacz punktów – propozycja zmiany systemowej? Kilka dni temu miałem przyjemność wygłosić wykład na zaproszenie Polskiego Towarzystwa Filozoficznego. W wystąpieniu zatytułowanym Praktyki komunikacyjne we współczesnej nauce starałem się pokazać, jak można filozoficznie interpretować przemiany, które dokonują się w komunikacji naukowej: a dokładniej w publikowaniu artykułów naukowych (od powstania czasopism naukowych XVII w. do wyłaniania się nanopublikacji w XXI w.). Jest to zagadnienie, nad którym pracuję intensywnie już od dłuższego czasu – w przyszłym roku ukaże się moja monografia jako efekt tych prac. Po moim wykładzie odbyła się bardzo ciekawa dyskusja, w której skakaliśmy od ideacyjnych teorii kultury, przez publikowanie wyników negatywnych, po digital natives i Gold Open Acces – na prawdę inspirująca debata. Jeden z głosów zabrał dr Mieszko Ciesielski, który odnosząc się do moich rozważań, zapytał, co sądzę o pomyśle „Ogólnopolskiego Repozytorium Internetowego Humanistyki”. dr Mieszko Ciesielski, IKE UAM
Here's a Helpful Infographic on the Many Risks of Helicopter Parenting Below you'll find a nifty infographic produced by the folks at Yellowbrick detailing the consequences of everyone's favorite irritating childrearing trend: helicopter parenting. We've written a lot about this topic here at Big Think; our archives are a veritable smorgasbord of pieces detailing its effects and consequences. Our focus isn't merely because we like to helicopter the helicopter parents, but because shifts in how we raise our kids have resulted in a generation of young adults who lack critical thinking, self-reliance, and coping skills. And that sucks not just for said young adults, but also for everyone else who has to deal with their problems. The image below will shed some light on all these elements, as well as offer a more basic crash course for those still unfamiliar with this troubling trend: For additional information on and analysis of the items above, check out the Yellowbrick blog.
Computer Science - Landscape Study - The Center for Elementary Mathematics and Science Education The survey yielded a rich, wide ranging set of findings. However, when considered together, those findings lead to three main conclusions: As a field, computer science education professional development needs to move toward more coherence. Video Diagrams – Help your students visualize your instructions Adding animations to them not only caught the attention of the students but it really helped the students to understand what they are expected to do. The downside is that it seemed to require a certain level of technology in the classroom to utilize them effectively. You would need a screen, projector or at the very least an overhead camera. This isn’t always practical, especially if you teach at different locations and to different class sizes. I needed a way to make these diagrams more universal, so that they could be viewed from any tablet, mobile device or computer without worrying about formatting issues or installing additional apps. I decided that the best way would be to produce video diagrams. I have produced these three video diagrams for tekhnologic and they are free to download. Play the video and click on share in the top left-hand corner and you will see the option to download the video. Rotating Circles I might give the following instructions while playing the video: Take Care!
About Bones You probably don’t give much thought to your skeleton, even though it’s holding you together. Do you have as many bones now as you did when you were born? What’s the shortest bone in your body? How about that funny bone…is it even a bone? When it comes to bone health, Dr. By age 30, we’re already starting to lose bone density if we don’t exercise. Love This? Thanks for subscribing! “Most people don’t realize it when they’re deficient in vitamin D,” Stearns said in an interview with Care2. Check out The Cleveland Clinic infographic below to learn more about the bones that make up your skeleton. According to the National Osteoporosis Foundation, women 50 and younger and men 70 and younger need about 1,000mg of calcium a day. If you’re under age 50, you need 400 to 800 IU of vitamin D a day. Guidelines differ for children, pregnant women and women who are breastfeeding. If you don’t get enough calcium and vitamin D from your diet, talk to your doctor about dietary supplements.
