    Decision-thinking is not unlike poker—it often matters not only what you think, but also what others think you think and what you think they think you think. The mental process is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.

    The great mathematician John von Neumann was one of the founders of game theory. In particular , he showed that all games fall into two classes : there are what he called games of “ perfect information ”,games like chess where the players can't hide anything or play tricks : they don't win by chance , but by means of logic and skills . Then there are games of “imperfect information”, like poker, in which it is impossible to know in advance that one course of action is better than another.

    One mistaken idea about business is that it can be treated as a game of “perfect information”. Quite the reverse, business, polities, life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors, which would even puzzle the best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

    The organic food has gained a lot of [popularity as they are being considered as healthier and tastier.  A fair number of people advocate a large-scale shift to organic farming from conventional agriculture. But this might not seem well-founded.

    Since the mid-19^th century, conventional industrial agriculture has become incredibly efficient on a simple land to food basis. Conventional farming gets more and more crop per square foot of land, which can mean less wilderness needs to be transformed to farmland.

    To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer（合成肥料）each year, and all that nitrogen（氮）enables much faster plant growth. However, the cost is paid in vast polluted dead zones at the months of many of the world's rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment.

To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices — refusing artificial fertilizers and chemical pesticides –are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion—and people are making those purchases for their moral senses as much as their tongues.

    Yet a new meta-analysis in Nature does the math and comes to a hard conclusion: organic farming produces 25% fewer crops on average than conventional agriculture.

    In the Nature analysis, scientists performed an analysis of 66 studies comparing conventional and organic methods across 34 different crop species, from fruits to grains. They found that organic farming delivered a lower output for every crop type, though the difference varied widely. For crops like fruit trees, organic trailed（落后于）conventional agriculture by just 5%. Yet for major grain crops and vegetables – all of which provide the world's main calories – conventional agriculture outperformed organics by more than 25%.

    What that means is that while organic farming may be more sustainable than conventional agriculture, there are trade-offs（此消彼长）with each. So an ideal global agriculture system may borrow the best from both systems rather than upholding merely organic or conventional practices.

    Anyone who cares about what schools and colleges teach and how their students learn will be interested in the memoir(回忆录)of Ralph W. Tyler, who is one of the most famous men in American education.

    Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching while teaching as a science teacher in South Dakota and changed his major from medicine to education.

    Graduate work at the University of Chicago found him connected with honorable educators Charles Judd and W. W. Charters, whose ideas of teaching and testing had an effect on his later work. In 1927, he became a teacher of Ohio State University where he further developed a new method of testing.

    Tyler became well-known nationally in 1938, when he carried his work with the Eight-Year Study from Ohio State University to the University of Chicago at the invitation of Robert Hutchins.

    Tyler was the first director of the Center for Advanced Study in the Behavioral Sciences at Stanford, a position he held for fourteen years. There, he firmly believed that researchers should be free to seek an independent(独立的)spirit in their work.

    Although Tyler officially retired in 1967, he never actually retired. He served on a long list of educational organizations in the United States and abroad. Even in his 80s he traveled across the country to advise teachers and management people on how to set objectives(目标)that develop the best teaching and learning within their schools.

    On August 5 just after 7.30 pm, Mike Estepa suffered a massive heart attack. The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying he'd be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.

    Larissa Arthur was driving back to Calgary from a hike in Field, B. C. with a friend. It was a warm and sunny day, and the two were chatting when a flush of yellow caught Arthur's eyes. She immediately pulled off the road.

    As Arthur approached the figure, she feared the worst: Estepa was covered in ants and exhibited no signs of life. There was no pulse and he wasn't breathing." says Arthur. A bystander called 911 and Arthur, a registered nurse, started chest compressions. She and two other drivers took turns carrying out CPR for the next 15 minutes before medical teams arrived and whisked Estepa away.

    Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏骤停). How did this happen, and, why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his "angel".

    "It was emotional," says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the bike she was returning from that day was one of 100 she's planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. "I couldn't save my father's life." Arthur says, "but this was a chance for me to save someone."
