Han ändrade 40 vanor på ett år - Leva Micael Dahlén, 41, tar skumtomte efter skumtomte och doppar i smör, innan han med ett leende äter upp dem. Det ser otroligt äckligt ut. Ändå är det svårt att inte glädjas med denne rockstjärneprofessor i hans ätande. Han har precis, genom att bota sin smörfobi, klarat sitt nyårslöfte för 2014. Smörätandet blev nämligen den 40:e ändrade vanan – på ett helt år. – Det gick! Micael Dahlén blev ekonomiprofessor redan som 34-åring år 2008 vid Handelshögskolan i Stockholm. ”Vi är vad vi upprepade gånger gör. Det tog Micael Dahlén fasta på under 2014. En vana per vecka har han ändrat, med vissa uppehåll för lite välbehövlig vila från förändringen. – Det handlar om att göra en sak så in i Hälsingland mycket under de där sju dagarna. Förändring går fortare än man tror, bara du gör den tillräckligt mycket. – Anledningen till att förändring tar tid är att vi tror att det tar så lång tid. Varför ville du förändra dina vanor? – Det finns nog flera svar. – Ja, det var ju målet! Hur gick det?
Quantum control: How weird do you want it? - physics-math - 11 September 2014 Entanglement used to be the gold standard of the quantum world's weirdness, now a new and noisy phenomenon could give us all the benefits with less of the fuss RAYMOND LAFLAMME works in a magnificent-looking building. The Quantum-Nano Centre on the University of Waterloo campus in Ontario, Canada, boasts an exterior whose alternating strips of reflecting and transparent glass are designed as metaphors for the mysterious nature of the quantum world. Inside, it is even more impressive. What a shame, then, if all this cutting-edge engineering proves ...
A Dynamical Theory of the Electromagnetic Field "A Dynamical Theory of the Electromagnetic Field" is the third of James Clerk Maxwell's papers regarding electromagnetism, published in 1865.[1] It is the paper in which the original set of four Maxwell's equations first appeared. The concept of displacement current, which he had introduced in his 1861 paper "On Physical Lines of Force", was utilized for the first time, to derive the electromagnetic wave equation.[2] Maxwell's original equations[edit] In part III of "A Dynamical Theory of the Electromagnetic Field", which is entitled "General Equations of the Electromagnetic Field", Maxwell formulated twenty equations[1] which were to become known as Maxwell's equations, until this term became applied instead to a vectorized set of four equations selected in 1884, which had all appeared in "On physical lines of force".[2] Heaviside's versions of Maxwell's equations are distinct by virtue of the fact that they are written in modern vector notation. For his original text on force, see: .
At First His Friends Thought He Was Crazy For Buying a Dirty Garage To Live In…Then He Remodeled It When the internet dies, meet the meshnet that survives - 19 April 2014 If a crisis throws everyone offline, getting reconnected can be tougher than it looks, finds Hal Hodson during a test scenario in the heart of New York IN THE heart of one of the most connected cities in the world, the internet has gone down. Amid the blackout, a group of New Yorkers scrambles to set up a local network and get vital information as the situation unfolds. The scenario is part of a drill staged on 5 April in Manhattan by art and technology non-profit centre Eyebeam, and it mimics on a small scale the outage that affected New Yorkers after superstorm Sandy hit in 2012. The idea is to test whether communication networks built mostly on meagre battery power and mobile devices can be created rapidly when disaster strikes. I'm a volunteer node in the network, and an ethernet cable runs over my shoulders into a wireless router in my left hand. Other routers link up with mine from a few hundred metres away.

Molecules in a fluid not randomly arranged FOM PhD researcher Matthijs Panman and his colleagues from the University of Amsterdam have demonstrated that molecules in liquid alcohol are not randomly oriented with respect to each other. The angle between the oxygen-hydrogen bonds of two neighbouring alcohol molecules is usually about 120 degrees. This discovery refutes the commonly held idea that molecules in a liquid are randomly arranged. The researchers published their work on 12 November 2014 in Physical Review Letters. In school we learn that molecules in a liquid are randomly arranged. But is that completely correct? Light and vibrations The FOM researchers, working at the Van 't Hoff Institute for Molecular Sciences in Amsterdam and in collaboration with the Amsterdam Center for Multiscale Modeling, devised an experiment to observe the local ordering. The light used is polarised, which means that the electric field of the light has a fixed direction. 120 degrees Explore further: Directly visualizing hydrogen bonds
What the world values, in one chart The more globalized our world becomes, the more we learn about similarities and differences that cut across all cultures. These things are sometimes easy to trace on a small scale. For instance, it's easy to chart the religious differences between, say, Indonesia and China. In 2000, 98 percent of Indonesians said religion was important to them compared to just 3 percent of Chinese citizens who said the same thing, according to WVS. But not every cultural comparison is that easy to make. Two professors, however, are finding ways to compare how our values differ on a global scale. Using data from the World Values Survey (WVS), professors Ronald Inglehart of the University of Michigan and Christian Welzel of Germany's Luephana University comprised this amazing Cultural Map of the World. The Ingelhart-Welzel Cultural Map of the World. What you're seeing is a scatter plot charting how values compare across nine different clusters (English-speaking, Catholic Europe, Islamic, etc.).
Quantum death: How the cosmic speed limit got frozen - physics-math - 27 March 2014 Zombie universe (Image: Edward Kinsella) Light speed is no limit in the quantum world – so why can't we exploit that freedom? Perhaps because we're living in the dead husk of a richer cosmos AS ENDINGS go, it is a bit of an anticlimax. This "heat death" of the universe was a favoured topic of the gloomier sort of 19th-century physicist. Antony Valentini, a theoretical physicist at Clemson University in South Carolina, is less ...
This Garden In A Bottle Has Been Thriving Since 1960: Sealed in its own ecosystem and watered just once in 53 years The Daily Mail has a fascinating feature on David Latimer and his soon to be 54-year-old bottle garden that he started on Easter Sunday back in 1960. Using a ten gallon carboy, Latimer poured in some compost, a quarter pint of water and carefully lowered in a spiderwort seedling (Tradescantia) using a piece of wire. He then placed the bottle garden by a sun-filled window in his home and let photosynthesis do its thing. It wasn’t until 1972 (12 years later) that Latimer gave his bottle garden another drink and it has been sealed ever since! - Bottle gardens work because their sealed space creates an entirely self-sufficient ecosystem in which plants can survive by using photosynthesis to recycle nutrients - The eco-system also uses cellular respiration to break down decaying material shed by the plant. - The water in the bottle gets taken up by plants’ roots, is released into the air during transpiration, condenses down into the potting mixture, where the cycle begins again

This Fungus Is Known As “The Mushroom Of Immortality” & “The King Of All Herbs” We're creating a positive news network. We need your help. Chaga is a non-toxic fungal parasite that grows on birch trees (as well as a few other types) in Northern climates. It is far from your typical soft and squishy mushroom, it actually looks and feels like burnt wood or charcoal. Chaga is known by the Siberians as the “Gift From God” and the “Mushroom of Immortality.” The Japanese call it “The Diamond of the Forest,” and the Chinese refer to it as the “King of Plants.” This mushroom of immortality is said to have the highest level of anti-oxidants of any food in the world and also, the highest level of superoxide dismutase (one of the body’s primary internal anti-oxidant defenses) that can be detected in any food or herb. Chaga is extremely powerful because it contains within it, the actual life force of trees -the most powerful living beings on this Earth.
