Explaining the explosion: rate of white dwarf mergers matches frequency of type Ia supernova Measuring vast distances in the Universe requires standard candles, objects with a known intrinsic brightness. Type Ia supernovae (SN Ia) are the brightest standard candles we know of, so they are useful for measuring the accelerating expansion of the Universe, as honored by the 2011 Nobel Prize in physics. Most astronomers agree that type Ia supernovae have something to do with white dwarfs—compact remnants of stars similar to our Sun. However, the exact mechanism for turning these stars into a supernova is not at all certain. Now, a study of white dwarfs by Carles Badenes and Dan Maoz indicates that the frequency of white dwarf mergers is very close to the rate of SN Ia events in spiral galaxies. White dwarfs are the cores of stars that were once similar to our Sun, but have since used up their hydrogen and helium fuel that makes them shine. However, if enough mass is added, the degeneracy pressure will not be able to overcome gravity.
What the Sony breach means for security in 2015 The recent (and perhaps ongoing) Sony breach was certainly one of the worst corporate data breaches we have seen to date. As 2014 draws to a close, no one knows the details with certainty of who the perpetrator was. Even so, it’s undeniable that it’s a breach that will forever change the way Sony does business. [ Questions remain after FBI charges North Korea with attack on Sony Pictures ] As the year of information security ends in 2014, what does the Sony breach tell us about what will happen in 2015? This was yet another wake-up call – but many will still sleep through it. What does this mean for 2015? If the Farmer's Almanac did data breach predictions; then it would certainly forecast 2015 as a devastating year. A good CISO is important; great security architects are critical – while a CISO may get the glory; security architects are what most organizations need.
Solar eclipse of May 20, 2012 Visibility[edit] North America It was the first annular eclipse in the continental U.S. since the solar eclipse of May 10, 1994 which was also the previous eclipse of this series Solar Saros 128. Photo Gallery[edit] Asia Related eclipses[edit] Solar eclipses 2011-2014[edit] Each member in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the moon's orbit. Note: Partial solar eclipses on January 4, 2011, and July 1, 2011, occur in the previous semester series. Saros 128[edit] It is a part of Saros cycle 128, repeating every 18 years, 11 days, containing 73 events. Series members 52-62 occur between 1901 and 2100: Metonic series[edit] The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles.

Partners Project Learning Tree For 35 years, Project Learning Tree (PLT) has been taking kids outside to learn. How? Each year, 30,000 educators attend 1,500 PLT professional development workshops around the country to learn the many ways they can get their students outdoors and learning about nature, while also meeting state and national academic standards. PLT is a program of the American Forest Foundation. THE DARK SITE OF PSYCHIATRY In this page you'll find links to articles and critical documents on biological-psychiatry. Biological-psychiatry's official theory describes psychological or personal problems as having a biological origin caused by genetic or chemical 'imbalances' to be corrected by drugs and other interventions like Electro-Convulsive Therapy [ECT] or insulin shock. These widely used but controversial methods in official medicine have been for many years amply invalidated, showing clearly that they are absolutely unscientific, that they tend to alienate patient's rights, are unable to solve the problems presented, are dangerous for one's health, and are submissive to pharmaceutical companies.

physicscentral Neuroscience For Kids - stroop effect The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s. Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should say "RED". Try this Interactive Stroop Effect Experiment. [Run Experiment] Also available: print out Stroop Test Mini Cards. Why? The words themselves have a strong influence over your ability to say the color. Speed of Processing Theory: the interference occurs because words are read faster than colors are named.Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words. I think that this puzzle would be easier for a very young child than for older children or adults. My scores: Test #1 = 10.1 seconds; Test #2 = 22.4 seconds It took me more than TWICE the amount of time to read the "confusing" words. More experiments to try:
Missing link found? Scientists unveil fossil of 47 million-year-old primate, Darwinius masillae Tama/Getty The 47 million year old fossilized remains of a primate is seen at the American Museum of Natural History in New York. Feast your eyes on what a group of scientists call the Holy Grail of human evolution. A team of researchers Tuesday unveiled an almost perfectly intact fossil of a 47 million-year-old primate they say represents the long-sought missing link between humans and apes. Officially known as Darwinius masillae, the fossil of the lemur-like creature dubbed Ida shows it had opposable thumbs like humans and fingernails instead of claws. Scientists say the cat-sized animal's hind legs offer evidence of evolutionary changes that led to primates standing upright - a breakthrough that could finally confirm Charles Darwin's theory of evolution. "This specimen is like finding the Lost Ark for archeologists," lead scientist Jorn Hurum said at a ceremony at the American Museum of Natural History. "It is the scientific equivalent of the Holy Grail. rschapiro@nydailynews.com
Overcoming the Fear of Who We Are and Finding Our Most Magnetic Qualities Who we really are is sometimes one of those most terrifying things for us to come to terms with. In fact sometimes when we look back at our lives, we realize we’ve done just about everything in an effort to have people who approve of us. Yet, what’s strange is that this has the opposite effect. In college I went through a phase where I decided to experiment with not giving a shi#$3 what anybody thought. Charisma is an interesting thing. How we Lose Our Charisma Critics: Critics always emerge no matter what you are doing. Social Programming: Social programming is perhaps one of the most detrimental mind viruses in our society. If you have ever seen the movie Twins, it’s interesting to note that Arnold Schwarzenegger’s character is extremely charismatic, but has never been exposed to anything but books, and a somewhat sheltered upbringing on a beautiful island. Imperfection: A while back I wrote about the difference between success and perfection. Enjoyed This Post and Want More?

Disclaimer: I don't own Criminal Minds nor am I making a profit A/N: This is just a fun little something I wrote to pass some time. 99 Things Most People Don't Know About Spencer Reid He's never been out of the United States. When he was 7, he conducted an experiment to see if deliberately hurting himself would snap his mother out of an episode. He lost his virginity when he was 15 at a college party. He's had approximately 3 girlfriends—the first one cheated on him, the second one only dated him to further her professional status, the other one stole money from his bank account. He's afraid everyone secretly hates him. The reason he doesn't drive much is because when he was 18, he accidently ran over a dog. He was hospitalized when he was 2 for falling off a bridge- he wanted to see if he could fly. When Emily faked her death, he went to see his mother. He can't swim.
7 Amazing Life Lessons from Ralph Waldo Emerson Ralph Waldo Emerson was an American philosopher, lecturer, essayist, and poet. He’s probably most known for leading the Transcendentalist movement of the mid-19th century. His work has influenced nearly every generation of thinker, writer and poet since his time. So without further adieu, today I want to talk about some of the profound life-lessons we can learn from Emerson. 7 Amazing Life Lessons from Ralph Waldo Emerson: Lesson 1: Aim Above The Mark “We aim above the mark to hit the mark.” To hit the mark, it’s necessary to aim above the mark. Do you aim high when setting your goals? Lesson 2: What You Always See, You Stop Seeing “If the stars should appear but one night every thousand years how man would marvel and stare.” What you constantly see, you stop seeing! Lesson 3: Conquer Daily “He who is not everyday conquering some fear has not learned the secret of life.” Life is a battlefield; to succeed you must “divide and conquer.” Lesson 4: Work on Yourself Lesson 5: Repair Your Character
