Study finds 'science' makes people sing YMCA




From The Age

Catchy tunes have a scientific "X-factor" that make them singalong hits, British experts have revealed.

Researchers wanted to know why certain songs inspired unabashed wedding guests and clubbers to belt out their favourites in public.

They solved the karaoke conundrum after observing thousands of volunteers as they lent their voices to a long list of tunes.

Singalong songs contained four key elements, the scientists discovered.

These were: long and detailed musical phrases, multiple pitch changes in a song's "hook", male vocalists, and higher male voices making a noticeable vocal effort.

Using this formula, the researchers then compiled a list of the 10 most singalong-able hits.

Number One was We are the Champions by rock group Queen.

Taking the next five places in the singalong chart were YMCA by Village People, Fat Lip by Sum 41, The Final Countdown by Europe, and Monster by The Automatic.

Music psychologist Dr Daniel Mullensiefen, from Goldsmiths University of London, said: "Every musical hit is reliant on maths, science, engineering and technology; from the physics and frequencies of sound that determine pitch and harmony, to the hi-tech digital processors and synthesisers which can add effects to make a song more catchy.

"We've discovered that there's a science behind the singalong and a special combination of neuroscience, maths and cognitive psychology can produce the elusive elixir of the perfect singalong song.

"We hope that our study will inspire musicians of the future to crack the equation for the textbook tune."

The findings were released to coincide with the final call for entries to Britain's 2012 National Science and Engineering Competition, which is open to young people undertaking science and technology projects.

Ex-Queen guitarist Brian May commented: "Fabulous, so it's proved then? We truly are the champions."

Male vocalists are important because singing along to a song is a "subconscious war cry", the researchers believe.

Psychologically, people looked to men to lead them into battle.

Vocal effort indicated high energy and purpose, especially when combined with a smaller vocal range.

Examples of "high effort" male singers included Freddie Mercury of Queen and Jon Bon Jovi.

Other songs on the singalong list included Ruby by the Kaiser Chiefs, I'm Always Here by Jimi Jamison, Brown Eyed Girl by Van Morrison, Teenage Dirtbag by Wheatus, and Livin' on a Prayer by Bon Jovi.

Why natural talent is overrated

From The Age September 20, 2011 - 4:36PM

Very few of the world’s great achievers were born with any real degree of talent, according to the book Talent is Overrated, by Geoff Colvin.

The book covers great performers from all fields, examining how much of a part talent played in their success.

For example Mozart was born to a father who was a professional music composer and an expert in teaching music, particularly to young men.

Tiger Woods was born to an amateur golfer who also studied the most effective strategies for training young men. Before Tiger could walk, his father would take him to the garage, sit him in his high chair and start to hit golf balls in to a net in the garage. “It was as if he was watching a movie,” Tiger’s father said, according to the book.

In both case studies, both Mozart and Tiger have been labeled through the ages as exceptionally talented. Yet when looking into their history it becomes apparent that there was more at work than just pure talent.

One of Tiger’s childhood coaches once remarked that Tiger “was like Mozart.” According to these accounts, indeed he was.

The research in the field shows that ‘talent’, a natural aptitude in a specific field, does exist yet when it comes to being great in a particular field, it is irrelevant.
So what makes all the difference?

Francis Galton, who authored the book Hereditary Genius in 1869, coined the term “nature versus nurture”.

Galton argued that people had innate limits in what they could achieve in life, and regardless of the work they put in, they would never break past these predetermined boundaries. At which time, it’s best if they just accept it, stay within their boundaries and “find true moral repose in an honest conviction that he is engaged in as much good work as his nature rendered him capable of performing’’. In other words, give up and be content.

This explains a lot of the thought patterns in our culture that surround great performers and the notion that they operate at an unattainable standard. You either have it or you don’t.

Over 100 years has passed but the research continues. Hundreds of studies have been done on the subject; the employees whose performance had plateaued for years, seemingly hitting their “rigidly determinate natural limits”, only to a see a consistent improvement in performance after new incentives were offered.

In his now famous paper, The Role of Deliberate Practice in the Acquisition of Expert Performance, Anders Ericsson concludes that “the search for stable heritable characteristics that could predict or at least account for superior performance…has been surprisingly unsuccessful’’. Meaning after countless case studies, researchers found no relationship between natural talent and great performance.

However at the time of this paper, “natural talent” was still the favoured theory when it came to high achievers. To this the authors indicate, “the conviction in the importance of talent appears to be based on the insufficiency of alternative hypothesis’’. That means people believe in ‘talent’ because they don’t have an alternative.

Until now.

Recent research indicates that the number one determinant when looking at the greats is what has become known as ‘deliberate practice’.

This is not the same as saying ‘experience matters’. Often people who have 20 years experience are found to be performing at a lesser standard to those that have been in a particular field for five years.

Experience alone does not make the difference. Practice alone will not make you great. For example you may go to the driving range and hit golf balls for an hour, going through the motions, making your way through the irons and eventually getting the drivers. However if there isn’t specific concentration and thought going into every stroke and it is simply a form of entertainment, this doesn’t constitute deliberate practice.

It can be similar for people who have remained in the same industry for 20 years. If they haven’t been constantly learning more, seeking feedback and bettering themselves it may be more like one year of experience repeated 20 times.

Deliberate practice has been found to encompass five characteristics:

1. It is designed specifically to improve performance

The exercise often needs to be designed by a teacher or mentor who understands what your weaknesses are and what needs to be done to improve.

The activities need to be designed to stretch you and push you outside your comfort zone. Tiger Woods will drop a golf ball into a sand bunker, step on it, and then play the stroke and he will do that thousands of times until he is exhausted. Tiger may only play that stroke a handful of times through his career, but when he comes to it he is well rehearsed in how to execute.

2. It can be repeated a lot

Repetition counts. Repetition alone however is not good enough, but when focusing on a particular skill-set with a clear outcome, there needs to be high repetition.

In business this can be achieved through role-play and rehearsal. When preparing for a high stakes show in Madison Square Garden on New Year’s Eve, Chris Rock performed 18 dress rehearsal evenings in small clubs across America, perfecting his material with every laugh.

3. Feedback on results is continually available

In business, feedback is everywhere and often it comes in the form of failure; a proposal that didn’t get through, a presentation that didn’t hit, a deal which fell over. Rather than looking at these experiences as failures, if we can examine what happened and take from it an understanding of what to do differently next time, there is our feedback. This is best done with a mentor or manager.

4. It is highly demanding mentally

Several studies have shown that four or five hours a day seems to be the most we can engage in deliberate practice. This is due to the mental exhaustion that accompanies it.

Even professional athletes that may be hitting more tennis balls in a day than most people do in a year, report that at the end of the day it is the mental exhaustion, not the physical exhaustion, that is most obvious.

5. It isn’t fun

Often people can have a romantic notion of what it is to be an ‘entrepreneur’. These notions don’t usually make it past the first year.

Doing what we’re good at is enjoyable. However when you take what you are good at, hone in on your weaknesses and repeat a deliberately designed exercise to the point of mental exhaustion, often it is not fun.http://www.blogger.com/img/blank.gif

This is of course a good thing. If it were easy – everyone would be doing it.

The research highlights that when looking at business moguls such as Branson, Gates or Trump, we no longer have an excuse to write them off as being “on another level” or “unbelievably talented.” Admittedly these people may be on another level today, however the studies show that they weren’t born there. It was through hours, years and decades of deliberate practice, that they were able to attain a level of performance somewhat resembling greatness.

As Colvin concludes: “great performance is not reserved for a preordained few. It is available to you and everyone

Scientists lose hypersonic aircraft on test flight



From The Age August 12, 2011

Hopes of fast-tracking an experimental aircraft that could fly from Sydney to London in 49 minutes have taken a nosedive with US military scientists today losing the plane during testing.

They launched the hypersonic aircraft but lost contact with the experimental plane as it flew over the Pacific Ocean in its second test flight.

The Defense Advanced Research Projects Agency (DARPA) says the unmanned Falcon hypersonic technology vehicle (HTV-2), designed as a global bomber prototype capable of a mind-boggling 20 times the speed of sound, launched successfully from California aboard a Minotaur IV rocket.



But after the plane separated from the rocket in the upper reaches of the atmosphere for its "glide" phase, contact was lost, DARPA says.

"Range assets have lost telemetry with HTV2," DARPA wrote in a Twitter post after the launch.

The agency provided no other details about the flight or how long it had been separated from the rocket.

Last year, scientists lost contact with the HTV-2 after nine minutes in its inaugural flight.

The hypersonic plane, which is supposed to travel at Mach 20, or 21,000 km/h, could potentially provide the US military with a platform for striking targets anywhere on the planet within minutes using conventional weapons.

Such a weapon, still in development, is part of what the US Air Force has dubbed "prompt global strike" capability.

"The ultimate goal is a capability that can reach anywhere in the world in less than an hour," DARPA said on its website.

In theory, the Falcon could travel between New York City and Los Angeles in less than 12 minutes.

Unlike a ballistic missile, a hypersonic vehicle could manoeuvre and avoid flying along a predictable path. Moreover, analysts say it would not be mistaken for a nuclear missile, avoiding the possibility of triggering a nuclear confrontation.

But Loren Thompson, an analyst at Lexington Institute with links to the defense industry, said there was still much work to be done before the hypersonic bomber becomes a reality.

"The military has a long way to go before hypersonic vehicles are ready for deployment," Thompson told AFP.

After separating from the rocket on Thursday, the Falcon undertook some manoeuvres before contact was lost, DARPA said.

The test flight plan called for the Falcon to eventually roll and dive into the Pacific Ocean.

The overuse of a chemical that helps fruit grow faster is cauhttp://www.blogger.com/img/blank.gifsing a rash of exploding watermelons in eastern China.

An investigative report by China Central Television found farms in Jiangsu province were losing hectares of fruit to the problem.

It said farmers sprayed too much growth promoter, hoping they could get fruit to market before the season and make more money.

Three-headed fish found on Sunshine Coast

More mutant fish have been found at a Noosa fish hatchery, including mullet embryos with two and three heads.

The discoveries come after seven mullet - four females and three males taken from the Noosa River, were given to the Sunland Freshwater Fish Hatchery at Boreen Point for breeding this month.

Fifty per cent of embryos found during two separate spawning events on July 5 and 6 had some form of cell abnormality, including some with two heads. A single mullet fry was found with three heads.

Advertisement: Story continues below Some of the mutant eggs and embryos have been preserved for scientific testing, while authorities will attempt to retrieve seven mullet and other abnormal material after Sunland staff disposed of them.

The mutant fish are the second batch of abnormal specimens to appear at Sunland, after the discovery of two-headed bass larvae sparked a Department of Primary Industries and Fisheries inquiry last year.

Owner Gwen Gilson has complained that chemicals sprayed at a nearby macadamia farm may be to blame for the genetic defects and large numbers of fish deaths at Sunland.

Last month, the Noosa Fish Health Investigation Taskforce's first interim report found it was "possible" chemical sprays caused the mass fish deaths and deformities, however, the report failed identify the chemical at fault or its source.

Last week, Primary Industries and Fisheries Minister Tim Mulherin said a full investigation would be carried out over the fresh discoveries and more Noosa River fish Bred at a bribie Island testing facility in an effort to pinpoint the problem.

"The incident will be included in the taskforce's broader investigation into any links between fish health problems at the hatchery and the local Noosa River ecosystem," Mr Mulherin said.

Meanwhile, Ms Gilson said her fish hatchery business was "going down the tubes" and she could not keep up with the number of samples biosecurity authorities needed to do testing.

"We are the only ones handing over information; but if you only have half the data how can you work out whats happening?" she told The Sunshine Coast Daily.

"All the neighbours are scared when they hear the tractors (spraying) they (the farm) do not have to tell us when they are doing it."
