Will black ever get out of style?

Popular culture has such a gr8 effect on our brains that we start attaching a emotional significance for each for some black may remind them black magic, and may evoke corresponding emotions..i think the limbic system in the brain plays a gr8 role here...because whatever we see evokes an emotion...and these collective emotions are transformed into styles, trends, fashions and popular culture in the long run and carried on through generations...

Black is my fave color..reminds of my graduation day!Its called the color of knowledge right? but in my society black is not worn on festivals and other auspicious occasions...although i dont believe in this personally..

Fun trivia- what is a 'Google doodle'?

On certain occasions, the logo on Google's webpage will change to a special version, known as a "Google Doodle". Clicking on the Doodle links to a string of Google search results about the topic. The first was a reference to the Burning Man Festival in 1998, and others have been produced for the birthdays of notable people like Albert Einstein, historical events like the interlocking Lego block's 50th anniversary and holidays like Valentine's Day.

Here is the latest commemoration of Confucius, the great chinese philosopher.

Diamonds 'may be the ultimate MRI probe'

Diamonds are a woman's best friend, they say. Now, a new study has claimed that the gems may soon turn out to be a patient's best
friend as well.

An international team, led by scientists from Harvard University, has carried out the study and found that diamond, formed of pure carbon, occasionally has minute imperfections within its crystalline lattice.

A common impurity is a "nitrogen vacancy", in which two carbon atoms are replaced by a single atom of nitrogen, leaving the other carbon atom space vacant. Nitrogen vacancies are in part responsible for diamond's famed luster, for they are actually fluorescent.

According to the scientists, the slight variations in this fluorescence can be used to determine the magnetic spin of a single electron in the nitrogen. Spin's quantum property that has a value of either "up" or "down", and therefore could represent one or zero in binary computation.

The team's recent achievement was to transfer this quantum information repeatedly between the nitrogen electron and the nuclei of adjacent carbon atoms, forming a small circuit capable of logic operations.

Reading a quantum bit's spin information--a fundamental task for a quantum computer--has been a daunting challenge, but the team demonstrated that by transferring the information back and forth between the electron and the nuclei, the information could be amplified, making it much easier to read.

Laws that choke creativity- TED talks(This one is thought provoking!Must watch)

This is really awesome! Something that should be looked into seriously by Authorities. The Freedom of Speech, that the young generation wants, is fueled by digital technologies. And sooner or later, we have to realize, the more we supress this with meaningless laws, the more we see these kind of things. A fair law system has to come, that will let unleash full potential of this generation.

The Power of Temptation « Bit Rebels

To test the power of temptation on children, Walter Mischel at Stanford University conducted a ‘marshmallow experiment’ with a group of children in the 1960s. According to YouTube, “A group of four-year olds were given a marshmallow and promised another, only if they could wait 20 minutes before eating the first one. Some children could wait and others could not. The researchers then followed the progress of each child into adolescence, and demonstrated that those with the ability to wait were better adjusted and more dependable (determined via surveys of their parents and teachers), and scored an average of 210 points higher on the Scholastic Aptitude Test.”
