The Basics of Math—Made Clear

    Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数) and beyond.

    The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.

    Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing—and completely understandable—field of study.

    By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery(神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.

    Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious. From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary.

    With a PhD in Mathematics Education from Georgia State University, Dr. Siegel teaches mathematics at Central Arizona College. His courses include various make-up classes and a number of lectures for future primary school teachers.

    When Boris left school, he could not find a job. He tried hard and he wrote letters to many companies until he could not afford to buy any more stamps. Boris began to lose his confidence, then depressed. Still he went on trying and still he failed. He began to think that he had no future at all.

    “Why don't you start your own business?” one of his uncles told him. “The world is a money-locker. You'd better find a way of opening it.”

    “But what can I do?”

    “Get out and have a look round.” advised his uncle. “See what people want; then give it to them, and they will pay for it.”

    Boris began to cycle around the town and found a suitable piece of waste ground in the end. Then he set up his business as a cycle repairer. He worked hard, made friends with his customers and gradually managed to win his good fame. A few months later, he found that he had more work than he could deal with by himself. He found a number of empty shops but they were all no good: in the wrong position, too expensive or with some other problems. But at long last, he managed to find an empty shop in a new place where there were plenty of customers but no competition.

    Boris and his assistant taught themselves how to repair motor-cycles. Slowly but surely the profits increased and the business developed. At last, Boris had managed to open the money-locker and found bank notes and gold coins inside.

    Good news! Job offered.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity（长寿）? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times. Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger. Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    People like to post their selfies(自拍照) on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.

    People who post selfies and use editing software to make themselves look better show behavior connected to narcissism(自恋), the researchers said. Makana Chock, a professor from Syracuse University, said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to "work towards satisfying their own vanity." Those "likes" under their Facebook selfies make them feel good.

    Besides, people who post group selfies show a need for popularity and a need to belong to a group, the research found. Some people feel "peer(同伴) pressure" to post selfies and some follow the popular belief that if there is no picture of an event or experience, it did not really happen. "Anyway, it shouldn't be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm," Chock said.

    Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. But men who post selfies showed more of a need to be seen as popular than women who posted selfies.

Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. That was the old way of "clicking like". On social media, however, people can decide not to look at photos — even if they click "like".

Sonya took Rupert, a rescue dog, back home three years ago, and soon found it liked attacking strangers and other animals, which she believed was caused by pain.

It took Sonya a year to develop a normal relationship with Rupert, during which she learned it was afraid of being left alone and also couldn't walk properly. Finally, she decided to take it to see a vet (兽医). After examining Rupert, the vet said its leg was broken, and it needed an immediate operation.

But when it had to go in for an operation on its leg, there was a problem—the vet Mike couldn't get near the dog. Mike and Sonya were left scratching their heads until one of them came up with an idea. Sonya said Rupert slept on a mouse suit so she suggested that Mike put it on.

At first, the dog barked wildly when Mike tried to operate on it in usual clothes. To make his patient feel at ease, Mike decided to dress up in the mouse clothes to see if it would be less worried. Amazingly, it worked. It stopped barking and immediately became good friends with Mike when he put on the suit. As a result, he was able to perform an operation on the leg safely and the result was quite satisfying.

After the successful operation, Mike hugged the dog around the neck, which isn't usually well-received by pets. Mike tried to be as respectful of its needs as possible and made time to give some attention. What Mike had done created a special experience or event in the dog's life.
