Overconfidence Can Give You A Competitive Edge at Work | The Wheelhouse. Want to gain social status? Be certain in your judgments, whether or not you are qualified to make them. Want to rise to the top? Assess yourself to be more skilled than you actually are. And here’s the kicker: new research suggests that even when your guarantees turn out to be wrong and your bold decisions result in unmitigated disasters, you will still gain respect and influence.
I spoke with Matthew Hutson, science writer and author of “The 7 Laws of Magical Thinking: How Irrational Beliefs Keep Us Happy, Healthy, and Sane,” to find out why overconfident people reap elevated social status—and if a blowhard backlash is ever coming. In general, do people have an inflated estimation of their abilities? It’s clear that overconfidence is prevalent. What is the payoff to overconfidence? Recent research by Cameron Anderson and colleagues at Berkeley finds that overconfident people achieve higher status. How does real confidence differ in presentation than the brash false confidence? Top 10 Demonstrations with Tuning Forks. New Perspectives: Imagining a 4D World. Representation of different spacial dimensions via LearnSomething Regardless of your scientific background (or lack thereof), the 4th dimension is very a difficult concept to grasp.
To understand just how difficult it is to envision a world with a 4th spacial dimension, let’s use a couple comparisons. First, imagine a color that doesn’t currently exist. Next, try to come up with a way to explain how an everyday color looks (like blue, for example) to someone who can’t see. Both of those things are pretty difficult, right? Well, we run into exactly the same problems when we try to imagine a 4th dimension to space. Even for those of us with the most powerful visual imaginations, trying to picture how a 4 dimensional object would look in a 3 dimensional world is impossible. However, math offers us a little assistance in this area. So in short, understanding a world with 4 spacial dimensions is still exceedingly difficult…but, what fun would we be if we didn’t try?
Right, now what? Best Explanation of Quantum Field Theory That You Will Ever Hear, Provided by Sean Carroll in Less than 2 Minutes at the 46th Annual Fermilab Users Meeting. Ics students devise concept for Star Wars-style deflector shields. If you have often imagined yourself piloting your X-Wing fighter on an attack run on the Death Star, you'll be reassured that University of Leicester students have demonstrated that your shields could take whatever the Imperial fleet can throw at you. The only drawback is that you won't be able to see a thing outside of your starfighter. In anticipation of Star Wars Day on 4 May, three fourth-year Physics students at the University have proven that shields, such as those seen protecting spaceships in the Star Wars film series, would not only be scientifically feasible, they have also shown that the science behind the principle is already used here on Earth.
They have published their findings in the Journal of Special Physics Topics, a peer-reviewed student journal run by the University's Department of Physics and Astronomy. In the Star Wars movies, the latest of which began filming in April, spaceships are protected by a shield defence system that deflects enemy laser fire. Wisdom from a MacArthur Genius: Psychologist Angela Duckworth on Why Grit, Not IQ, Predicts Success. By Maria Popova “Character is at least as important as intellect.” Creative history brims with embodied examples of why the secret of genius is doggedness rather than “god”-given talent, from the case of young Mozart’s upbringing to E. B. White’s wisdom on writing to Chuck Close’s assertion about art to Tchaikovsky’s conviction about composition to Neil Gaiman’s advice to aspiring writers. But it takes a brilliant scholar of the psychology of achievement to empirically prove these creative intuitions: Math-teacher-turned-psychologist Angela Duckworth, who began her graduate studies under positive psychology godfather Martin Seligman at my alma mater, the University of Pennsylvania, has done more than anyone for advancing our understanding of how self-control and grit — the relentless work ethic of sustaining your commitments toward a long-term goal — impact success.
In this short video from the MacArthur Foundation, Duckworth traces her journey and explores the essence of her work: A Slower Speed of Light.

Amazing 2D Rubens’ Tube Visualizes Sound With a Plane of Fire. German physicist Heinrich Rubens became a god among nerds in 1905 when he invented a tube that uses fire to visualize standing sound waves. When there is no sound fed into the tube, the flames rise to the same height. When a sound is added into the tube, the waveform actually affects the amount of gas that is fed through each hole. At the point of maximum displacement on the wave (the anti-node), the gas pressure varies. The pressure is highest when the wave crests and the gas is pushed closer to the hole, which forces more fuel out and causes the flame to grow higher. The part of the wave which crosses the midline and remains unchanged is referred to as the node. Of course, volume plays a big role on how these flames appear. Derek Muller from Veritasium traveled to Denmark in order to check out an updated version of the Rubens tube.
The results are pretty amazing. You found a planet!: Robert Simpson crowdsources scientific research. Scientific research is generating far more data than the average researcher can get through. Meanwhile, modern computing has yet to catch up with the superior discernment of the human eye. The solution? Enlist the help of citizen scientists.
British astronomer and web developer Robert Simpson is part of the online platform Zooniverse, which lets more than one million volunteers from around the world lend a hand to a variety of projects — everything from mapping the Milky Way to hunting for exoplanets to counting elephants to identifying cancer cells — accelerating important research and making their own incredible discoveries along the way. At TED2014, Simpson took us through a few of Zooniverse’s 20-plus projects (with more on the way), some of which have led to startling discoveries — including a planet with four suns. Below, an edited transcript of our conversation. Are you a scientist? Well, I’m a distracted astronomer.
So you’re giving volunteers the grunt work, basically? A lot. Prepare to Have Your Mind Blown by a Balloon and a Minivan. Why is glass transparent? - Mark Miodownik. Mathematical Impressions: The Bicycle Pulling Puzzle. If you pull straight back on the lower pedal of your bicycle, will the bike move forward or backward? This classic puzzle has a surprising twist, so be sure to think about it carefully before watching the answer in this video. The puzzle is discussed in many publications, but none of them present the whole story shown here, as far as I know. For partial solutions, see Martin Gardner, Mathematical Carnival (Random House, 1975), p. 182, or D. E. Daykin, “The Bicycle Problem,” Mathematics Magazine 45, no. 1 (Jan. 1972), p. 1.

Kelemen, R. Seston Schillaci, and P. Abstract Adaptation by natural selection is a core mechanism of evolution. Adaptation by natural selection is central to understanding the complexity and functional specialization of living things. The misconceptions about adaptation are varied. With regard to understanding the source of the problem, developmental research points in an important direction.
Given these findings, recommended timetables for exposing children to explanations of adaptation are a cause for concern. Experiment 1 Method Participants Materials and procedure.

Travel INSIDE a Black Hole. What Will We Miss? Fun, interesting science? 10 amazing online sources. In today’s TED Talk, Tyler DeWitt makes a fantastic case for a simple idea: make science fun. Educators and writers get caught up in the idea that science needs to be taken seriously, and forget that the best way to get kids interested is to… make it interesting.
Too much emphasis on being accurate can lead to lessons that are incomprehensible, or just flat-out boring. The money quote from DeWitt: Tyler DeWitt: Hey science teachers -- make it fun“If a young learner thinks that all viruses have DNA, that’s not going to ruin their chances of success in science. But if a young learner can’t understand anything in science and learns to hate it because it all sounds like this, that will ruin their chances of success.” Now to the good news. Minute Physics.

By Maria Popova The history of physics is the history of modern civilization. How did humanity go from a tribe governed by superstition to a species on the hunt for the Higgs Boson and the deepest secrets of the cosmos? In The Universe in a Nutshell, theoretical physicist and prolific author Michio Kaku — who has previously helped us unravel the mysteries of time — explores why “the history of physics is the history of modern civilization.” From the Big Bang to E=mc2 to the latest bleeding-edge advances in string theory and quantum mechanics, Kaku offers a concise and accessible history of physics, while shining a light on the discipline’s promise to bring us closer to the secrets of existence.
Almost everything you see in your living room, almost everything you see at a modern hospital, at some point or other, can be traced to a physicist. In contextualizing the role of physics in the development of modern civilization, Kaku quotes legendary science fiction author and futurist Arthur C. Demystifying Mass ft. Sean Carroll.
