Need inspiration？Happy background music can help people get the creative juice flowing.

Simone Ritter, at Radboud University Nijmegen in the Netherlands, and Sam Ferguson at the University of Technology Sydney, Australia, have been studying the effect of silence and different types of music on how we think.

They divided 155 volunteers into five groups. Four of these were each given a type of music to listen to while taking a series of tests, while the fifth group did the tests in silence. The tests were produced to judge two types of thinking: divergent thinking, which refers to the process of creating new ideas, and convergent thinking, which is how we find the best solution to a problem. Ritter and Ferguson found that people were more creative when listening to music they thought was positive, coming up with more special ideas than the people who worked in silence.

"We also performed other types of music that were sad, anxious and calm, and didn't see this effect, " says Ferguson. "It seems that the type of music present is important, rather than just any music." In addition, no type of music helped convergent thinking, suggesting that it's better to solve problems in silence.

Ritter and Ferguson write that their finding could be used to improve creative thinking in places like educational institutions or laboratories, but Irma at the University of Helsinki in Finland, says happy music may help creativity by setting off the release of dopamine, a brain chemical involved in pleasure and relief." Dopamine also increases creative thinking and goal-directed working, "says Irma. And she also thinks happy music may not help convergent thinking because this kind of thinking relies more on logic and less on creativity.

   Michelin inspectors，the super secret spies of the restaurant industry，are the anonymous（匿名的）keepers of the famous Michelin star rating. They've been writing anonymous reports of restaurants for over 100 years.

"We say it's a little like the CIA，"said inspector "M" with a laugh. She asked that her identity not be revealed. "My whole life is staying under the radar，staying away from cameras，using fake names，trying to steal in and out of restaurants quietly."

Along with their boss，Jean-Luc Naret，the director of the Michelin Guide，about 90 inspectors around the world decide which restaurants will win the cooking equivalent（等价物）of an Oscar，the Nobel Prize and Mega Millions jackpot（头奖）all at once. The Michelin Guide covers 23 countries，and out of the45，000 rated restaurants，less than 100 have the top rating — only nine American restaurants carry three stars.

If the name "Michelin" brings the tires on your car to mind，you're not too far off. The Michelin rating began in France in 1900 as a marketing trick. The Michelin brothers thought their customers would buy more tires if given a list of hotels and restaurants to explore.

Inspector "M" admitted being an inspector leads to a lonely dining life. " Most of the time we dine alone，"she said. "It gives us the ability to really focus on the food and the atmosphere and capture the entire experience. "To cover their tracks，"M" said sometimes two inspectors will dine together and write two separate papers. It's better than saying "table for one"，right？

"When you're really，really into food and very crazy about food，everything else that's going on around you isn't so important，" she said.
