Daydreaming Key To Solving Complex Problems

By Sunil Kumar

Daydreaming really is the key to solving complex problems, a new study has found.

Some of the most important scientific breakthroughs ever made – by everyone from Einstein to Newton – came about as the geniuses behind them allowed their minds to wander.

Now research by modern day scientists has shown that mere mortals can also improve their problem-solving ability in the same way.

The study showed that people who returned to a difficult task after taking a break and doing an easy task boosted their performance by around 40 per cent.

But there was little or no improvement for people who did another demanding task during the break, used it to rest or did not have a break at all.

 

Scientists who carried out the study said the results indicate that doing simple tasks that allow us to daydream is key to solving trickier questions playing on our minds.

“Many influential scientific thinkers claim to have had their moments of inspiration while engaged in thoughts or activities not directly aimed at solving the problem they were trying to solve,” said lead author Benjamin Baird, of the University of California, Santa Barbara.

“This study demonstrated that taking a break involving an undemanding task improved performance on a classic creativity task far more than taking a break involving a demanding task, resting or taking no break.

“The findings arguably provide the most direct evidence to date that conditions that favour mind wandering also enhance creativity.”

The research, published in the journal Psychological Science, is likely to please school pupils and bored office workers who enjoy gazing out of the window but may not go down less well with teachers and bosses.

Einstein is believed to have begun his theory of relativity while he daydreamed about riding or running beside a sunbeam to the edge of the universe – after he was expelled from school for rebelling against rote learning.

Newton developed his theory of gravity after he happened to see an apple fall from a tree in his mother’s garden in Lincolnshire.

Further back the Greek philosopher Archimedes shouted ‘Eureka’ when he stepped into a bath and realised the relation between the rising water level and the volume of his body that was submerged.

The study involved 145 people aged between 19 and 32 who were given two minutes to list as many unusual uses as possible for everyday objects. They were then split into four groups with one of the groups not allowed any break from the task. The other three groups were each given a 12-minute break during which some carried out a demanding memory task, some enjoyed complete rest and some did an undemanding task.

Those who did the undemanding task were found to be daydreaming a lot about personal issues or past or future events as a result of its ease.

All participants were then asked to return to the task of listing unusual uses for ordinary obobjects. When considering new items all groups did the same. But when considering the same objects as earlier, daydreamers improved their performance by 40 per cent while the other groups performed the same as before.

The researchers said the improved performance was associated with “a higher level of mind wandering but not with a greater level of explicitly directed thoughts about the task.” They added that the “seemingly dysfunctional mental state” of daydreaming may “serve as a foundation for creative inspiration”.

The authors suggested that we may unconsciously process thoughts while concentrating on another task but said more research is needed to explain more fully how this happens.

The Brain’s Storage Capacity

By Sunil Kumar

Neuroscientists estimate the storage capacity of the brain to be around 10 and 100 terabytes. It is difficult to estimate how much of that space is “used space” versus “free space” is very difficult—the brain is simply much more complex than an external hard drive. And the old myth that we use 10% of our brains is a myth. According to scientists, information is stored everywhere.

A group of Chinese engineers have smashed the records for quantum teleportation, by creating a pair of entangled photons over a distance of approximately 100 kilometres.

According to these scientists, quantum entanglement is the mysterious phenomenon where two particles become tightly intertwined and behave as one system — whether they are next to each other on a laboratory bench, or either sides of a galaxy.

Alcoholics from the world unite, you can now know what beer tasted like a few centuries back.

Scientists from the VTT Technical Research Centre said they analyzed two bottles of beer discovered in 2010 that came from a ship believed to have sunk in the 1840s off the Aland Islands in the Baltic Sea, Reuters has reported.

The researchers also added that they found living bacteria in the bottles that helped them retain a pale golden color and could originally have had hints of rose, almond and cloves. They said it’s possible that a smoky flavor in beer was appreciated at the time. Based on this brewers may recreate the blend.

The World May Not End Soon: Newly Found Mayan Calendar

dgj6138  the acropolis recommend reading 300x199 The World May Not End Soon: Newly Found Mayan CalendarBy Sunil Kumar

For all of you who watched the movie 2012, and have been reading about the prophecies, here’s some interesting news. The world may not end this year.The walls reveal the oldest known astronomical tables from the Maya. Scientists already knew they must have been keeping such records at that time, but until now the oldest known examples dated from about 600 years later.

Astronomical records were key to the Mayan calendar, which has gotten some attention recently because of doomsday warnings that it predicts the end of the world this December. Experts say it makes no such prediction. The new finding provides a bit of backup: The calculations include a time span longer than 6,000 years, meaning it could extend well beyond 2012.

Quantum Dots Used To Build RGB Laser

Make crystals of silicon small enough – less than 10 nanometres – and their tiny dimensions can then change the way atoms behave and react in the presence of other things.

These tiny bits of semiconductor crystals – so-called quantum dots – have such remarkable, novel properties that scientists think they will soon be used in everything from light bulbs to imaging of cancer cells or in the design of ultra-efficient solar cells.

Instead of looking for brand new materials to build different devices, then, quantum dots make it possible to use a single type of semiconductor to produce a range of different characteristics etc.
