I just found out about TED-Ed. I love the 8min animation format.
You can filter by video duration, student level and indeed, topics.
There are also a "Clubs" and "Series" sections that looks promising, but there isn't much details on those. The Series are curated spaces, but beside the titles, there isn't much background info on the editorial lines and the very reason why the series' topics is relevant for the student.
The Artistic Direction is not consistentn but since topics are very diversified, this doesn't prevent an enriching experience - on the contrary, it can potentially renew the vanishing attention of students where a RSA Animation might set too much of narrative constraint.
Digital Displacement [...] merges a computer with a more traditional hydraulic engine and allows the engine to shut parts of itself off as needed. It's granular enough to disable certain pistons the instant before they fire, if they're not necessary at a particular moment. Specifically, if the engine isn't running at full load, Digital Displacement prevents unnecessary piston strokes from robbing the engine of energy, thereby increasing the efficiency of the whole engine
This might give wind power a boost in productivity.
"The tech is already being put to use in 7 megawatt turbines off the coast of Glasgow and Fukushima, the world's largest floating wind turbines. You can bet there are more to come."
Blackmarket for Useful Knowledge and Non-Knowledge is a concept conceived and developed by Hannah Hurtzig and Mobile Academy Berlin in which experts from diverse fields (natural scientists, craftsmen, artists, philosophers, and neighbors) partake in a series of parallel one-on-one dialogues with members from the audience. The audience (rather a customer on this evening) can book an expert and his or her offer of knowledge for half an hour. Learning and unlearning, knowledge and non-knowledge, and strategies of living and surviving change ownership in a non-institutional way. Blackmarkets have been staged in Berlin, Warsaw, Vienna, Riga, Tallin, Liverpool, Jaffa and other places. For its 18th edition and for the first time in France it comes to Musée de l`Homme in Paris.
interesting initiative where experts in various fields meet "regular" folks and share ther knowledge for 30min. - assuming the latter do not know anything about their field.
Hannah Hurtzig first "select" the experts acording to their ability to vulgarize teir knowledge, their openess and other social skills.
For experts, it is also a unique opportunity to gather with other high level people and share their views.
LEGO has announced a plan to develop sustainable manufacturing materials that would allow the toy company to ditch plastic forever. The Denmark-based company is investing millions to create a Sustainable Materials Centre to employ over 100 people who will carry out the search for a better building block. The company aims to identify a sustainable plastic alternative by 2030.
Controlled nuclear fusion – a clean, near-perpetual source of energy – would revolutionize the world. In recent years, significant steps on the path to a fully operational, efficient fusion reactor have been made, and this week another milestone has been reached: German engineers from the Max Planck Institute have successfully fired up their nuclear fusion reactor
"A rival fusion reactor design, the “tokamak,” is currently being built in France by a multinational effort of scientists and engineers. The International Thermonuclear Experimental Reactor (ITER) takes the form of a doughnut-shaped containment vessel. Due to a series of technical problems and rising construction costs, however, it has yet to carry out its first experiment, meaning that the German stellarator has pipped them to the post."
The result of three years of research at MIT's Fluid Interfaces Lab, Valentin Heun's Reality Editor is an augmented reality app that lets you link the smart objects around you together, just by drawing connections with your finger between them.
"Internet of Things should actually empower users to have more control over the world around them, not take it away."
Principal avantage de cette première pile Na-ion : réduire l’utilisation du lithium. L’exploitation de cet or blanc, qui s’intensifie avec le succès des appareils électroniques nomades et des voitures électriques, pose déjà de nombreux problèmes écologiques, notamment en Amérique du Sud. Alors que les réserves de sel sont mieux réparties sur la planète et 1 000 fois plus abondantes, ce qui impacte également le coût de revient.
When Elon Musk unveiled and open-sourced his design for the Hyperloop, his futuristic solar-powered supersonic pod-train, in the summer of 2013, it seemed like something straight out of a science-fiction book, and many thought that's where the idea would stay. But since then, groups of dedicated forward-thinking individuals have been trying to actually make it happen.
First test in January 2016 by Hyperloop Technologies - based on Elon Musk's 57 pages .pdf white paper :)

Relatively cheap drones with advanced sensors and imaging capabilities are giving farmers new ways to increase yields and reduce crop damage.
Drones can provide farmers with three types of detailed views. First, seeing a crop from the air can reveal patterns that expose everything from irrigation problems to soil variation and even pest and fungal infestations that aren’t apparent at eye level. Second, airborne cameras can take multispectral images, capturing data from the infrared as well as the visual spectrum, which can be combined to create a view of the crop that highlights differences between healthy and distressed plants in a way that can’t be seen with the naked eye. Finally, a drone can survey a crop every week, every day, or even every hour. Combined to create a time-series animation, that imagery can show changes in the crop, revealing trouble spots or opportunities for better crop management.
Data-driven agriculture using tech to pilot crop growing and farm management.
A team of researchers from the California NanoSystems Institute at UCLA has found a new way to use enzymes to remove pollutants from water that is cost- and energy-efficient, able to remove multiple pollutants at once, and minimizes risks to public health and the environment.
"Scientists previously had shown that polluted water could be cleaned using enzymatic activities of naturally occurring bacteria and fungi, which breaks down pollutants into their harmless chemical components. But that method carries the risk of releasing dangerous organisms into the water.
The new UCLA technique, developed by a team led by Shaily Mahendra, a UCLA associate professor of civil and environmental engineering, and Leonard Rome, a professor of biological chemistry and associate director of CNSI, is a variation of that method. The researchers put enzymes into nanoscale particles called "vaults," then deposit the tiny particles into polluted water."
The Wind Lens focuses the power of the wind to the centre of the hoop, intensifying the power in a similar way a magnifying glass does with the sun's rays. With their unique floating hexagonal bases, the Wind Lens might also win over the many detractors of wind turbines who claim they are an ugly blight on the landscape.
Ohya added: "Despite its merits, even if this technology does enter the market in Japan, it may not be easily adopted by other countries, due to differing intensities and directions of wind conditions."
very promising tech if it succesfully increase by 2 to 3 times the amount of energy produced.
The concept behind Ontenna is a device that can allow the user to feel sound through their hair kind of like how cats can sense movement in the air with their whiskers. By translation sounds in the 30dB to 90dB range into 256 different levels of vibration and light, the pattern and quality of sounds can be expressed through light and vibration. Through this, the rhythm, pattern, loudness, and other qualities of sounds can be conveyed to the user.
tweaking the intensity of the device is the real challenge as it appears that everyone has different perception level on various part of the body - yet it can provide very basic feedback such as referee blowibg the whistle... hence the deaflympics target release I guess
The course will also introduce participants to TensorFlow, the open-source deep learning platform Google unveiled back in November. Deep learning, a division of machine learning through which machines detect and classify patterns in data, is the driving force behind Google Photos' search engine and the company's speech recognition technology.
It's great to see GAFAs opening up to share some knowledge. They might have realized that if they want to find the 5-legged sheep they're looking for, they must train them temselves :)
Scientists say they have taken a step towards making the dream goal of nuclear fusion more achievable, by identifying the location of energy in a process known as fast ignition.
" As mentioned, fast ignition is – as its name states – just the ignition process that gets the nuclear fusion process going. Actually containing and utilizing any resulting high-temperature plasma remains difficult.
But progress is being made. Towards the end of last year, German scientists successfullyfired up their experimental Wendelstein 7-X (W7X) nuclear fusion reactor, which took 19 years to build. This so-called stellarator can only produce a plasma for a tenth of a second – but it’s a start.
And over in France, there’s the continuously delayed International Thermonuclear Experimental Reactor (ITER), which is expected to produce its first plasma next decade. Both W7X and ITER would benefit from this more efficient fast ignition process to spark their plasmas. "
Professor André Füzfa, from the Universite de Namur in Belgium, thinks we have the technology to create and manipulate weak artificial gravitational fields. The claim is bold but grounded. Füzfa has calculated that by using very strong magnets, it’s possible to create tiny distortions in the space-time [...] Our ability to manipulate fundamental forces, especially electromagnetism, has had a huge impact on our way of life, so learning to create small gravitational fields could have long-lasting consequences for our technological development.
A hand-worn robotic device is being developed that will help millions of blind and visually impaired people navigate past movable obstacles or assist in their ability to pre-locate, pre-sense and grasp an object.
The researchers say that their solution is a "lightweight form-fitting device that attaches to the hand using key locations for cameras and mechanical and electrical sensors [...] The technology will combine vision, tactile, force, temperature and audio sensors and actuators to help the wearer pre-sense an object - telling its location, feeling its shape and size - and then grasp it."
The input - feedback will be triggered through haptic and audio cues.
Not sure if this would greatly improve the life of blind people as they develop senses to "make-do"... like feeling the density of obstacles.
But this technology could also benefit the robotics research in many ways!
Despite the drawbacks, scientists are confident that Apple ResearchKit’s open source framework, which reveals the code used to create the research apps, will inspire Android developers to create tools to reach their users.
It's a good example of how it is increasingly important to have real conversations on the costs / benefits of personal data records. If there could be a trustworthy framework, this could truly boost relevance in everything - from healthcare to many other fields.
But when it comes to trusting an institution, Google and Apple aren't making the top of the list.
Silicon Valley is in the midst of an artificial intelligence war, as giants like Facebook and Google attempt to outdo each other by deploying machine learning and AI to automate services. But a brand-new organization called OpenAI—helmed by Elon Musk and a posse of prominent techies—aims to use AI to "benefit humanity," without worrying about profit.
WE'RE JUST TRYING TO CREATE NEW KNOWLEDGE AND GIVE IT TO THE WORLD.
The organization features an all-star group of leaders: Musk and Altman are co-chairs, while Google research scientist Ilya Sutskever is research director and Greg Brockman is CTO, a role he formerly held at payments company Stripe.
For Musk, it is a reunion gig with Paypal's Peter Thiel from Palatin, LinkedIn founder Reid Hoffman and Y Combinator CEO Sam Altman who funded OpenAI as a non-profit organization with $1billion that will make its work, including intellectual property available to the public.
Communications devices transmit energy in many different frequency ranges, or bands. The team's scavenging devices can capture this energy, convert it from AC to DC, and then store it in capacitors and batteries. The scavenging technology can take advantage presently of frequencies from FM radio to radar, a range spanning 100 megahertz (MHz) to 15 gigahertz (GHz) or higher.
Scavenging experiments utilizing TV bands have already yielded power amounting to hundreds of microwatts, and multi-band systems are expected to generate one milliwatt or more. That amount of power is enough to operate many small electronic devices, including a variety of sensors and microprocessors.
not the first "thin air" tech seen out there in the last few weeks, but this one seems to be using a variety of frequencies
In a process called "methane cracking," the molecular components of methane – hydrogen and carbon – are separated at temperatures of over 750° C (1,382° F), without harmful emissions.
"According to Professor Thomas Wetzel of KIT, the reactor produces hydrogen with a 78 percent conversion rate at 1,200° C (2,192° F), while operating continuously for two weeks. It's this latter aspect that offers the most hope for an eventual reactor built to industrial scale, which would be powered by the produced hydrogen."
There's a lot disruption happening — and it may cost you your job.
A 300-page report released by Merrill Lynch in November
- The auto industry is going to change big-time, especially when fully autonomous — aka driverless — cars officially go mainstream.
- The biggest change to the financial sector will likely come from "robo-advisors" that will replace investing pros.
- The hospital of the future is going to have robots helping with everything from critical surgery to caring for elderly and disabled patients.
- Only 10% of worldwide manufacturing tasks are automated right now. That's expected to increase to 45% over the next 10 years as robots get much cheaper.
- Agriculture will also see big changes, with more driverless tractors, drones, and milk bots joining the farm.
- The service industry will be changed as more personal robots — machines able to do jobs that are easy, dangerous, or repetitive — are introduced.
AI technologies such as software that can make predictions or think much like humans do (or better) could be a $43 billion industry by 2024. But "full AI" — a computer being able to truly emulate human thought — has only a 50% chance of happening by 2040-50. That goes up to 90% by 2075. There is an AI downside of course. The report predicts a reduction in "knowledge work" to the tune of 230 million jobs worldwide, and some have argued that AI could produce "killer robots."
Here is another read I shared recently about an example of "human accountability" and tech & human working together instead of one substituting for the other http://sco.lt/8DhNzd
Most everyday electrical and electromechanical objects emit small amounts of electromagnetic (EM) noise during regular operation. When a user makes physical contact with such an object, this EM signal propagates through the user, owing to the conductivity of the human body. By modifying a small, low-cost, software-defined radio, we can detect and classify these signals in real-time, enabling robust on-touch object
Great potential - even though nobody reall need instructions on how to operate a door knob :)
Researchers from Tufts University, Brown University, and Rensselaer Polytechnic Institute are teaming with the U.S. Navy to explore technology that would pave the way for developing robots capable of making moral decisions.
"The ONR-funded project will first isolate essential elements of human moral competence through theoretical and empirical research. Based on the results, the team will develop formal frameworks for modeling human-level moral reasoning that can be verified. Next, it will implement corresponding mechanisms for moral competence in a computational architecture."
That's quite a task these researchers have at hand!
And that's it! the real space exploration adventure can finally starts now that Bezos' company Blue Origin brought Venture Capitalists' tech battle way up there and brought it back!
They succesfully launched a rocket up to the Von Karman line where space begins. They are not the only one, BUT they are pretty much the only that got the rocket back - which is a very important first step to make space exploration affordable and sustainable.
