Gini coefficient of national income distribution around the world. This is based on 1989 to 2009 data, estimated by the CIA. Some are pre-tax and transfer, others post-tax income. The Gini coefficient (also known as the Gini index or Gini ratio) (/dʒini/) is a measure of statistical dispersion intended to represent the income distribution of a nation's residents. The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income). There are some issues in interpreting a Gini coefficient. Definition Graphical representation of the Gini coefficient The graph shows that the Gini coefficient is equal to the area marked A divided by the sum of the areas marked A and B. that is, Gini = A / (A + B). The Gini coefficient is usually defined mathematically based on the Lorenz curve, which plots the proportion of the total income of the population (y axis) that is cumulatively earned by the bottom x% of the population (see diagram). where and

The Daily GalaxyIn February, 1971, Apollo 14 astronaut Edgar Mitchell experienced the little understood phenomenon sometimes called the “Overview Effect”. He describes being completely engulfed by a profound sense of universal connectedness. Without warning, he says, a feeing of bliss, timelessness, and connectedness began to overwhelm him. He describes becoming instantly and profoundly aware that each of his constituent atoms were connected to the fragile planet he saw in the window and to every other atom in the Universe. He described experiencing an intense awareness that Earth, with its humans, other animal species, and systems were all one synergistic whole. He says the feeling that rushed over him was a sense of interconnected euphoria. Rusty Schweikart experienced it on March 6th 1969 during a spacewalk outside his Apollo 9 vehicle: “When you go around the Earth in an hour and a half, you begin to recognize that your identity is with that whole thing. This is done with Faraday cages.
Listen, Little Man!What Does Your Body Language Say About You? How To Read Signs and Recognize Gestures - Jinxi Boo - Jinxi BooArt by LaetitziaAs we all know, communication is essential in society. Advancements in technology have transformed the way that we correspond with others in the modern world. Because of the constant buzz in our technological world, it's easy to forget how important communicating face-to-face is. Body language is truly a language of its own. 10% from what the person actually says40% from the tone and speed of voice50% is from their body language. Lowering one's head can signal a lack of confidence. Pushing back one's shoulders can demonstrate power and courageOpen arms means one is comfortable with being approached and willing to talk/communicate The lowering of the eyes can convey fear, guilt or submissionLowered eyebrows and squinted eyes illustrate an attempt at understanding what is being said or going onA lack of confidence or apprehensiveness can be displayed when you don't look another person in the eyesOne tends to blink more often if nervous or trying to evaluate someone else
Are We Really All Made of Stars? | Cosmos, Moby’s Song ‘We Are All Made of Stars’, Universe & Solar System | Life's Little MysteriesThe theory that everyone and everything on Earth contains minuscule star particles dates back further than Moby's popular 2002 song "We Are All Made of Stars." In the early 1980s, astronomer Carl Sagan hosted and narrated a 13-part television series called "Cosmos" that aired on PBS. On the show, Sagan thoroughly explained many science-related topics, including Earth's history, evolution, the origin of life and the solar system. "We are a way for the universe to know itself. Some part of our being knows this is where we came from. We long to return. His statement sums up the fact that the carbon, nitrogen and oxygen atoms in our bodies, as well as atoms of all other heavy elements, were created in previous generations of stars over 4.5 billion years ago. "All organic matter containing carbon was produced originally in stars," Impey told Life's Little Mysteries. How star stuff got to Earth When it has exhausted its supply of hydrogen, it can die in a violent explostion, called a nova.
Stock trades to exploit speed of light, says researcher23 March 2011Last updated at 03:20 By Jason Palmer Science and technology reporter, BBC News, Dallas Optimal high-frequency trading locations (blue) exist for pairs of major financial exchanges (red) Financial institutions may soon change what they trade or where they do their trading because of the speed of light. "High-frequency trading" carried out by computers often depends on differing prices of a financial instrument in two geographically-separated markets. Exactly how far the signals have to go can make a difference in such trades. Alexander Wissner-Gross told the American Physical Society meeting that financial institutions are looking at ways to exploit the light-speed trick. Dr Wissner-Gross, of Harvard University, said that the latencies - essentially, the time delay for a signal to wing its way from one global financial centre to another - advantaged some locations for some trades and different locations for others.

Why powerful people -- many of whom take a moral high ground -- don't practice what they preach2009 may well be remembered for its scandal-ridden headlines, from admissions of extramarital affairs by governors and senators, to corporate executives flying private jets while cutting employee benefits, and most recently, to a mysterious early morning car crash in Florida. The past year has been marked by a series of moral transgressions by powerful figures in political, business and celebrity circles. New research from the Kellogg School of Management at Northwestern University explores why powerful people - many of whom take a moral high ground - don't practice what they preach. Researchers sought to determine whether power inspires hypocrisy, the tendency to hold high standards for others while performing morally suspect behaviors oneself. The research finds that power makes people stricter in moral judgment of others - while being less strict of their own behavior. The research was conducted by Joris Lammers and Diederik A.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. Its content reflects the fact that my interest lies in history and philosophy of science and that I teach in a Department of History and Philosophy of Science. This text owes a lot to many. i i i
Jevons paradoxThe Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher). As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History The Jevons paradox was first described by the English economist William Stanley Jevons in his 1865 book The Coal Question. Jevons observed that England's consumption of coal soared after James Watt introduced his coal-fired steam engine, which greatly improved the efficiency of Thomas Newcomen's earlier design.
