12.08.2009 - Social scientists build case for 'survival of the kindest'
By Yasmin Anwar, Media Relations | 08 December 2009 BERKELEY — Researchers at the University of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive. (Photo illustration by Jonathan Payne) In contrast to "every man for himself" interpretations of Charles Darwin's theory of evolution by natural selection, Dacher Keltner, a UC Berkeley psychologist and author of "Born to be Good: The Science of a Meaningful Life," and his fellow social scientists are building the case that humans are successful as a species precisely because of our nurturing, altruistic and compassionate traits. They call it "survival of the kindest." Empathy in our genes "The tendency to be more empathetic may be influenced by a single gene,” Rodrigues said. Cultivating the greater good

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

Personal knowledge base A personal knowledge base (PKB) is an electronic tool used to express, capture, and later retrieve the personal knowledge of an individual. It differs from a traditional database in that it contains subjective material particular to the owner, that others may not agree with nor care about. Importantly, a PKB consists primarily of knowledge, rather than information; in other words, it is not a collection of documents or other sources an individual has encountered, but rather an expression of the distilled knowledge the owner has extracted from those sources. Definition[edit] The term personal knowledge base itself was coined in 2011 by Stephen Davies of the University of Mary Washington[1] and has a tripartite definition: personal: a PKB is intended for private use, and its contents are custom-tailored to the individual. Contrast with other classes of systems[edit] The following classes of systems cannot be classified as PKBs: Personal information management[edit] Historical influences[edit]

What Does Your Body Language Say About You? How To Read Signs and Recognize Gestures - Jinxi Boo - Jinxi Boo Art 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

Colour my world Colour does not exist. Not out in the world at any rate. All that exists in the world is a smooth continuum of light of different wavelengths. Colour discrimination begins with the absorption of light of different wavelengths. Colour information only arises by comparing the responses of multiple cone cells. The L/M system evolved much more recently, due to a gene duplication that occurred in the lineage of Old World primates, probably around 40 million years ago. All of this raises an important question – how are the inputs to these different cone cells compared? This has been known for quite a long time now. The new study by Field and colleagues worked out in breathtaking detail the circuitry of the retina at a cellular level. Their results reveal exactly such a bias and further show that it cannot be explained simply by random clumping of L or M cones in the photoreceptor array. A remarkable experiment performed a few years ago dramatically illustrates this principle.

Ensign Software - ESPL: Dances of the Planets The planets in the heavens move in exquisite orbital patterns, dancing to the Music of the Cosmos. There is more mathematical and geometric harmony than we realize. The idea for this article is from a book Larry Pesavento shared with me. The book, 'A Little Book of Coincidence' by John Martineau, illustrates the orbital patterns and several of their geometrical relationships. . Take the orbits of any two planets and draw a line between the two planet positions every few days. Earth: 8 years * 365.256 days/year = 2,922.05 days Venus: 13 years * 224.701 days/year = 2,921.11 days (ie. 99.9%) Watching the Earth-Venus dance for eight years creates this beautiful five-petal flower with the Sun at the center. (5 is another Fibonacci number.) Another intriguing fact is the ratio between the Earth's outer orbit and Venus's inner orbit is given by a square. In the following dance patterns, the planet pairing is given and the number of orbits of the outer planet. Article by Howard Arrington

We come from the future. This is, for the most part, an accurate article, except for a few statements. "Exactly what makes a fermion a fermion is a bit complicated, but suffice it to say that fermions are all the particles that deal with matter. So what about the last group of elementary particles, the ones that don't deal with matter? These are the bosons, and they deal with the fundamental forces of the universe." The statements above can be misinterpreted as suggesting that fermions are defined as particles that deal with matter and bosons are defined as particles that deal with forces. And that is not true. Particles that deal with matter are fermions and particles that carry the fundamental forces are bosons. What fermions and bosons really are have to do with two apparently unrelated (but actually related) particle properties: spin and statistics. "There are four known bosons" See, this is an example of the misconception I just mentioned. According to special relativity, not general relativity.

Domestic animals, like this water buffalo in Viet Nam, live intimately with humans and provide renewable resources to humans that communicate well with them. Photo by Greg Luna. 20 July 2010 — It's no secret to any dog-lover or cat-lover that humans have a special connection with animals. "Establishing an intimate connection to other animals is unique and universal to our species," said Shipman, a professor of biological anthropology. In addition to describing her theory in the scientific paper, Shipman has authored a book for the general public, now in press with W. These carvings are from ivory and have been dated to between 30,000 - 36,000 years old, making them the oldest artworks in Europe. Shipman suggests that the animal connection was prompted by the invention of stone tools 2.6-million years ago. Click on image for high-resolution version. [ Kevin Stacey ]
