20 Gifs That Teach You Science Concepts Better Than Your Teacher Probably Can. Not to critique teachers or anything (after all, I am one).
It’s just that these Gifs are astoundingly elegant. 1) This is a a Reuleaux Triangle (There are curves of constant width besides circles and spheres. It’s a convex planar shape whose width is the same regardless of the orientation of the curve) 2) And these Curves of Constant Width can drill square holes. Red Pitaya: the opensource electronic laboratory. Here we present a tool to measure and acquire data.
It is open source, and made by using the Xilinx Zynq 7010 Soc. It was funded with KickStarter and it is suited to be customized and adapted to various application exigencies. The idea, which required funds for 50.000$ for its creation, obtained instead over 256.000 $ (in funds) from the supporters. What is it about? Incredible Photographic Survey of Military Kits From 1066 to 2014 - My Modern Met. UK-based photographer Thom Atkinson's series Soldiers' Inventories is an incredibly extensive photographic survey of the military kits carried by British soldiers from 1066 to 2014.
With the goal of exploring what he describes as "the mythology surrounding Britain’s relationship with war," Atkinson enlisted the help of reenactment groups, collectors, historians, and serving soldiers in order to assemble the components of each inventory. With each kit marking a landmark battle in the last millennium, the series is an eye-opening look at what a soldier's material world is reduced to during times of war. Atkinson's project shows the remarkable similarities and differences between military kits separated by decades and even centuries.
Swords became guns; notepads became iPads; 18th-century bowls became mess tins. While tools have evolved considerably, the heart of the necessities—uniforms, weapons, equipment, and especially personal items—remain the same. Help make it happen for GravityLight, lighting for the developing countries. Zeolite thermal storage retains heat indefinitely, absorbs four times more heat than water.
Hold onto your hat/life partner/gonads: Scientists in Germany have created small, zeolite pellets that can store up to four times more heat than water, loss-free for “lengthy periods of time.”
In theory, you can store heat in these pellets, and then extract exactly the same amount of heat after an indeterminate amount of time. Zeolites (literally “boil stones”) aren’t exactly new: The term was coined in 1756 by Axel Cronstedt, a Swedish mineralogist who noted that some minerals, upon being heated, release large amounts of steam from water that had been previously adsorbed. For the last 250 years, scientists have tried to shoehorn this process in a heat storage system — and now, the Fraunhofer Institute, working with industrial partners, has worked out how to do it.
I will try to explain how this works, but the science is fairly complicated: When Fraunhofer’s zeolite comes into contact with water, a chemical reaction adsorbs the water and emits heat. New 'soft' motor made from artificial muscles. Public release date: 15-Feb-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Jennifer Lauren Leejlee@aip.org 301-209-3099American Institute of Physics "Perhaps the earliest public demonstration of an electric motor," writes a team of researchers from the University of Auckland in New Zealand, "involved the automatic rotation of a turkey on a spit over a fire" at a party put on by Benjamin Franklin in 1749.
Franklin's electrostatic motor was self-commutating, meaning that it was able to provide a continuous torque while it turned without requiring external electronics to control its progress. What causes language switching in bilinguals? The proficiency that a bilingual person has of both languages, the context in which he speaks them or unconscious changes in their use are the factors that make people who speak Spanish and Catalan switch from one language to another.
The group of Cognition and Brain Plasticity at the Bellvitge Biomedical Research Institute (IDIBELL), led by Antoni Rodríguez-Fornells, has designed a questionnaire that allows understanding individual differences among bilinguals when they change the language (switching). The study was conducted on a sample of 566 college students Spanish-Catalan bilingual and has been published in the latest issue of the journal Frontiers in Psychology. 2012 Annual Question.
"Metabolic syndrome" (MetSyn) has been termed the "Epidemic of the 21 st century. " MetSyn is an accretion of symptoms, including high body mass index (weight-for-height), high blood sugar, high blood pressure (BP), high blood triglycerides, high waist circumference (central/visceral fat deposition), and/or reduced HDL-cholesterol, the so-called "good" cholesterol. Epidemics of Obesity and diabetes are intertwined with, and accompany, the meteoric rise in MetSyn. Top 10 ways to save money through sharing. Sharing stuff and services conserves resources and builds our ties with our neighbors—but it also saves money, sometimes a lot of money.
The first step is to do an inventory and look at the ways you're already sharing; I bet you'll be surprised. Then ask yourself, what else can I share? Here are ten of our top suggestions, culled from a year's worth of content on Shareable.net—and we’d love to hear yours in a comment! 10. Printed Sensors Could Help Save You From Spoiled Food. Was this chicken safe even before it was fried?
Thinfilm could help us find out. Photo: Ariel Zambelich/Wired Whenever I pick up a package of frozen raw meat from the grocery store, I wonder, “Has this been frozen the whole time? How many times did it thaw and re-freeze?” Magnetoastrocoolness: How Cosmic Magnetic Fields Shape Planetary Systems. AUSTIN, Texas—Astrophysicists have a funny attitude toward magnetic fields.
You might say they feel both repelled and attracted. Gravitation is assumed to rule the cosmos, so models typically neglect magnetism, which for most researchers is just as well, because the theory of magnetism has a forbidding reputation. The basic equations are simple enough, solving them less so. Book Review: Our Magnetic Earth, by Ronald Merrill. A magnetic sense is now well documented in dozens of animal species.
It turns out that tracking the geomagnetic field—that same invisible thing that points compasses—is handy for life, in lots of situations. Using their internal compasses, naked mole rats in Africa navigate their pitch-black underground mazes. Lobsters off Bermuda find their way to regions of the seafloor where they congregate to spawn. Thrushes migrate south in the autumn and north in the spring. Alexander's Horned Sphere fractal changes how we define inside and outside. I think what they mean is that for a common sphere, everything is uniform enough to slip the band off again with no damage to the sphere or the band.
With a hrned sphere, because it branches off infintismally, any attempt to put a band around it will either damage the sphere, or damage the band becuae it gets snagged on a branch. It is clear as mud. Simple technique results in surprising repellency results. (PhysOrg.com) -- Anyone who has ever worn eyeglasses for any length of time can surely attest to the annoyance of constantly having to clean off the oil left behind by finger touching. Not only does it dirty the lens, but removal requires a solvent, rather than a simple tissue.
Doris Vollmer can relate, and that’s just what got her thinking about the soot given off by her Christmas candles. Phase-shift Plasma Turbine. Author: Moacir L. Ferreira Jr. 1. Presentation. E-Cat household fusion still sketch, may be in Home Depot in 2012. We're still not totally sold on the technology behind the E-Cat dirt cheap eco-friendly fully operational household cold fusion thing, mostly because things that seem too good to be true usually turn out to be exactly that way. But whether we believe it or not, household systems reportedly may be available in Home Depot later this year. According to the rather secretive people behind the Energy Catalyzer (or E-Cat), the breadbox-sized device uses a jump start of electricity to begin combining hydrogen with nickel via a special catalyst to generate heat. It doesn't emit any carbon and isn't radioactive, but it has about the same power density as a uranium fission reactor core.
