July/August 2011 > Features > Stanford Prison Experiment What happened in the basement of the psych building 40 years ago shocked the world. How do the guards, prisoners and researchers in the Stanford Prison Experiment feel about it now? It began with an ad in the classifieds. Male college students needed for psychological study of prison life. $15 per day for 1-2 weeks. More than 70 people volunteered to take part in the study, to be conducted in a fake prison housed inside Jordan Hall, on Stanford's Main Quad. The leader of the study was 38-year-old psychology professor Philip Zimbardo.
Flatland: A romance of many dimensions With Illustrations by the Author, A SQUARE (Edwin A. Abbott 1838-1926) To The Inhabitants of SPACE IN GENERAL And H. C. IN PARTICULAR This Work is Dedicated By a Humble Native of Flatland In the Hope that Even as he was Initiated into the Mysteries Of THREE Dimensions Having been previously conversant With ONLY TWO So the Citizens of that Celestial Region May aspire yet higher and higher To the Secrets of FOUR FIVE OR EVEN SIX Dimensions Thereby contributing To the Enlargement of THE IMAGINATION And the possible Development Of that most rare and excellent Gift of MODESTY Among the Superior Races Of SOLID HUMANITY The first objection is, that a Flatlander, seeing a Line, sees something that must be thick to the eye as well as long to the eye (otherwise it would not be visible, if it had not some thickness); and consequently he ought (it is argued) to acknowledge that his countrymen are not only long and broad, but also (though doubtless in a very slight degree) thick or high.
LaTeX Symbols From AoPSWiki This article will provide a short list of commonly used LaTeX symbols. Operators Relations Negations of many of these relations can be formed by just putting \not before the symbol, or by slipping an n between the \ and the word. Here are a few examples, plus a few other negations; it works for many of the others as well. Articles on "Electricity" Why three prongs?Why do wall outlets have three holes? "Grounding" and safety. Right Angle CircuitryDo Lenz' Law and the Right Hand rule still work... after you've been turned INSIDE OUT by that greasy black Fog?
invisibility cloak now a reality Nov. 12, 2012: A member of the lab at Duke University's Pratt School of Engineering has made a giant leap toward creating an invisibility cloak.Duke University Let's hope Star Fleet perfects the technology before the Romulans get their hands on it. Scientists have made the impossible possible, disappearing a cylinder by guiding light around it before putting those photons back on their original path -- essentially bending light around the object. This new approach achieves invisibility where others have failed. Contemplative Science and Practice: "How to Do Research You Love" Padam-lama Vajrasattva Heruka, Dorje Sempa with Vajragarvi In early January I presented a lecture on "Contemplative Science and Practice: How to Do Research You Love" to the Faculty Forum at the Wright Institute. I told my personal story (how a meeting with Paul Ekman, the world-famous emotion researcher upon whom the TV series "Lie to me" was based, directed me to Tibetan Buddhism and a Tibetan Buddhist practice). I told a research story, and provided an overview of current findings in contemplative science, including the findings from our own lab at the Wright Institute, the Emotion, Personality and Altruism Research Group (EPARG) ( A few days later, an opinion piece appeared in the Chronicle of Higher Education by Owen Flanagan, essentially trashing what he called "Hocus-Pocus Buddhism." I wish Flanagan had let us in on how he came to his conclusion.
Science & Environment Imagine if you could see time laid out in front of you, or surrounding your body. And you could physically point to specific dates in space. Important dates might stand out - birthdays, anniversaries. And you could scan a visible timeline - to check if you were available - whenever you made plans. No actual diary necessary. According to Julia Simner, a psychologist from the University of Edinburgh, there is a reasonable chance you can.
Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Special Relativity Special Relativity These pages are ok as far as they go, but they are missing the planned highlight, to show you what things actually look like when you travel at near the speed of light. I hope to have the opportunity to develop these pages further as time permits. Here is my opinionated Guide to Special Relativistic Flight Simulator Sites.
neuroscience of Imagination Albert Einstein said of the theory of relativity, "I thought of it while riding my bicycle." Anyone who exercises regularly knows that your thinking process changes when you are walking, jogging, biking, swimming, riding the elliptical trainer, etc. New ideas tend to bubble up and crystallize when you are inside the aerobic zone. What would Earth's skies look like with Saturn's rings? Posted By Jason Davis Topics: pretty pictures, art Illustrator and author Ron Miller specializes in, among other things, incredible visualizations of other worlds. He has rendered the surface of Titan, peered into black holes for Discover magazine, and designed a Pluto stamp that is currently hurtling toward the far reaches of our solar system aboard the New Horizons spacecraft.
