What’s not to love about a homemade sandwich?

BERLIN (AP) -- Computers may have us beat at chess and checkers, but new research suggests our brains still have an edge when it comes to solving certain tricky problems thanks to a very human trait: intuition.

Scientists in Denmark have found that people who played a game that simulated a complex calculation in physics sometimes did better than their silicon rivals.

"The big surprise we had was that some of the players actually had solutions that were of high quality and of shorter duration than any computer algorithms could find," said Jacob Friis Sherson, a physicist at Aarhus University who co-wrote the study published Wednesday in the journal Nature.

Experts say the results could advance the quest to develop effective quantum computers, something most major universities and several tech companies are working on as they seek to accelerate processing power. Such computers use individual atoms to store information and it's hoped they could one day outperform even the fastest conventional silicon-based supercomputers.

The problem that Sherson and his colleagues set out to tackle concerns the best way to control the atoms using laser beams before their quantum state is disturbed. Time is limited and the number of possibilities is vast, meaning that even advanced computers struggle to find the perfect solution.

The scientists decided to create a game called Quantum Moves , in which players had to perform essentially the same task by using their mouse to simulate the laser beams that pick up the atoms and move them around.

This approach -- known as gamification -- has been used for several years to solve other scientific problems, such as identifying types of galaxies based on their shape.

"Most of the other efforts deal with pattern recognition whereas our game is very dynamic and intuition-based," said Sherson.

The team found that players were able to outperform computers precisely because they didn't try all possible options one by one.

"One of the most distinctly human abilities is our ability to forget and to filter out information," he said. "And that's very important here because we have a problem that's just so complicated you will never be finished if you attack it systematically."

Frank Wilhelm-Mauch, a professor of theoretical physics at the University of Saarbruecken who wasn't involved in the study, said the Danish scientists had found a way to exploit the way humans intuitively find solutions to fairly complex problems by simplifying them, thereby achieving a solution that might not be as mathematically perfect as that produced by a computer but definitely more practical.

"The work looks extremely solid and the solution is totally plausible," he said.

Wilhelm-Mauch said the results of the study would likely affect the entire field of quantum computing, because similar problems exist "like sand on a beach."

The Danish scientists are hoping to build on their existing work as word of the game and its contribution to quantum physics spreads, drawing in more players.

The effort might also be seen as a response to the setbacks human players have suffered against computers in more traditional games recently. Last month AlphaGo, a program developed by Google to play the ancient strategy game Go, won 4:1 matches against humans, chalking up another major victory for artificial intelligence.

"It's slightly encouraging that there are problems where we humans are still superior to computer algorithms," said Sherson.

There really is nothing more convenient, satisfying and fulfilling to eat than a homemade sandwich. Whether it’s hot or cold, there are many different types of sandwiches that can satisfy a hearty appetite.

To learn more about the art of sandwiching, Rachel Belle spoke to the author of The Encyclopedia of Sandwiches Recipes, History and Trivia for Everything Between Sliced Bread, during this weekend’s “Ring My Belle“.

“When you think of food, I can’t think of anything more democratic than a sandwich,” author Susan Russo exclaimed. “It is humble, unpretentious; it’s easy to get along with. It’s kind of like anything goes, so what’s not to love about it?”

Some of the best sandwiches, according to Russo, are the ones that trigger a warm, sentimental feeling.

“When you think of some of your fondest food memories, how many times do you think of sandwiches?” Russo explained. “Whether it’s your school lunch sandwich that your mom packed for you, or the first time you had a real gourmet sandwich, or the first time you had kind of an iconic sandwich in a city that you were visiting — those experiences really stay with us because they have such an impact on us.”

Russo says her all-time favorite is a simple, homemade meatball sandwich because it was something her mom would make her for school lunch. She tells people that “she wouldn’t have made it through junior year chemistry class” without her mom’s famous sandwich.

“I think a lot of people feel the same way that your favorite is the one that brings you those warm and fuzzy feelings that you associate with comfort,” Russo explained.

While the book is a good way to try out different sandwich recipes, Russo says the best part are the stories and history behind each sandwich.

“That’s the joy of the book, at least for me. I absolutely love researching the history of these sandwiches and learning about their backgrounds.”

If you want to learn how to make a scrumptious pastrami that would make a New Yorker ask for seconds, Russo’s book has everything you need to make a top notch sandwich.

“While there are a lot of basic sandwiches that you already know of like the peanut butter and jelly, there are other sandwiches that you have probably never heard of or maybe never really knew how to make.”
