Facebook is an Internet-based social network site that lets people get in touch with family and friends and reach out to people with common interests around the world, all through computer. It is very popular, with more than 900 million users. If Facebook were a country, it would have about three times the population of the United States.

    Documents filed with US. financial regulators say Facebook has hundreds of millions of active users who send billions of messages each day and upload 250 million photographs on their personal pages. Facebook users have registered 100 billion “friends.”

    On Facebook, “Friending” someone means you add the person to your list of people you can communicate with directly, which often allows the person to see more information about you than you share with the general public.

    Facebook was started by Mark Zuckerberg and other students at Harvard University in 2004, and has grown at an amazingly fast pace.

    Facebook makes money when advertisers pay to get access to hundreds of millions of Facebook users. Advertisers can often direct their messages to the people most interested in their products because Facebook computers keep track of information that users place on their pages. For example, a person interested in diving, planning a wedding, looking for work, or suffering from diabetes(糖尿病) may see advertisements related to those topics.

    Facebook has become so much a part of the culture of the United States and other nations that it has been the subject of a Hollywood movie. It is a key marketing tool for many businesses, and its users' content has been used as evidence in some divorce or criminal cases.

    One of the most practical parts of my college education (and my entire education)was my student teaching. For six month, I gradually took over until I was completely teaching the class. It wasn't quite the same as a real teaching job. However, it was definitely a good way to get some real world experience. School should prepare students for the job market. Therefore, are our kids receiving enough practical education so they can be successful in the real world?

When teaching kids, it's important to be able to have a purpose for everything we teach. As parents and teachers, we should ask ourselves: what can this be used for when kids enter the job market? I can think about a college class I took where we had to analyze various movies. I honestly can't think of how analyzing "Rambo" benefited me. Perhaps, I would have been better off taking an auto shop class or a carpentry class. After all, I can't change a tire and I'm completely incapable when it comes to using power tools. The Guardian points out that the current generation is one of the most educated but lacks the skills to mend a hole in a shirt or put up a shelf. We have become a society that hires someone else to do these basic tasks. So how can we fix this?

    Perhaps, learning how to think is not enough. Rather than focusing on standardized tests so much, schools need to give students more practical application. Cooking is actually helpful when teaching children about fractions, measuring and multiplication. Students can learn how to double a recipe and see the relationship between 1/4 and 1/3 cup. As kids get into the upper grades, money management should be a focus. Making a budget and learning about interest rates are good ideas. I used to give my students real restaurant menus and a budged. They had to come up with what they could buy, including the tip with a set amount of money. In college, rather than only focus on the craft of writing, I wish I would have learned more about marketing and publishing my writing. Finally, internships in both high school and college should be required.

It appears that some high schools are doing a better job of preparing students for the real world. For instance, according to NBC News, in Michigan, "the Utica Center for Science and Industry uses technology to prepare students for automotive and military industry jobs." The program aims to combine students' skills with employers' needs. Students take optional courses in areas such as "multimedia, engineering or mechatronics" and also take part in activities where there isn't one right answer. For me, giving kids the opportunity to create is the key point. So far, the program is showing success.

According to a Gallup poll, fifty-seven percent of American workers say "the type of work they do generally" does not require "a bachelor's or a more advanced degree." Therefore, if a college degree isn't helping the majority of Americans at their job, then what is required? Many jobs require a skill. Electricians and contractors have specific skill that allow them to complete their jobs. Whether students go to four-year school or not, I think it's important for everyone to have a skill. After all, a Forbes article states that half of college graduates are working at jobs that don't require a degree. Clearly, being smart and qualified isn't always enough to make it in the real world.

    I'm going to encourage my kids to go to college and earn a degree. I'm also going to encourage them to think outside of the box and give them a practical education too. After all, you never know where life will take you.

    A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.

    According to course instructor William Barry, associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, a feat he described as “remarkable.” The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.

    Before becoming a student, Bina48 appeared as a guest speaker in Barry's classes for several years. One day when addressing Barry, s class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry. Therefore the challenge would be for Barry and his students to teach Bina48 what love is.

    “Some interesting things happened in the class,” said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is “fairly simple — it's a feeling,” said Barry. But the reality was different. Bina48 ended up learning “31 different versions of love,” said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.

    Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bina48 and NDNU classmates were the winners of this debate.

    In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.

    Hundreds of children are being treated for sleep problems in Wales every year. In some cases, babies, infants and teenagers have been admitted to hospital while in north Wales alone.

    The Children's Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child's health as healthy eating and exercise, and children with poor sleep patterns were more likely to be fat.

    Statistics obtained under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.

    Children aged between 0 and4 made up the highest number of inpatients (住院病人), with some newborns being treated for sleep-related problems from the day of birth.

    Vicki Dawson, who set up the Children's Sleep Charity (CSC), said sleepless nights were putting both children and parents in anxiety. "Their weight and growth may also be affected as well as their mental health," she said.

    Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn't concentrate for long periods.

    Psychologist Amy McClelland, of Sleep Wales, said a common problem was children being "over excited" and "not having the chance to relax property" before bed and families should get back to basics. "Think 1950s family home. Dinner as a family, read, chat, a film maybe, lights off and then bed." She added.

    Have you ever imagined what it would be like to see the world through an animal's eyes? For example, what a chimpanzee sees as it sits at the top of a tree, or a penguin's view as it dives into the sea to catch its dinner?

    These questions are answered in the nature documentary Animals with Cameras, produced by the BBC. The three-part series was first aired in the UK last month. To explore animal stories "told" by the animals themselves, the documentary's filmmakers worked with scientists to develop cameras that wild animals could wear.

    "Never before have we seen such high-quality footage (连续镜头)directly from the animal's point of view, " BBC Nature executive producer Fred Kaufman told PBS." This miniseries greatly expands our comprehension of animal behavior and this camera technology opens up new possibilities for discovering so much more."

    Indeed, the groundbreaking technology provides a new viewpoint of the animal kingdom. New cameras with enough battery life to shoot for hours at a time were designed to be comfortable enough for animals to wear, according to the documentary's camera designer Chris Watts.

    The technical challenges didn't stop there. Some animals were very curious about the equipment, with some even fighting each other for the chance to wear a camera. In the case of chimpanzees, "we had to create dummy (仿造的)cameras, so that every chimpanzee could get one", the miniseries' wildlife cameraman Gordon Buchanan told Live Science.

    For animals that were comfortable enough to be with human beings, the cameras could be fitted and removed by hand. But for others, the cameras came off automatically using a timed release and were collected afterward. This meant that the cameras needed to be as tough as possible.

    To avoid disturbing the animals, scientists who were good at dealing with wildlife came to help by putting the cameras on the animals." The last thing we want to do is cause them distress." the documentary's producer Dan Rees told the BBC. "To follow an animal in the first place, there had to be a clear benefit in terms of knowledge about it that might be useful to protecting a species in the future.

    Their efforts certainly paid off. " Footage that captures (捕捉)these rare and exciting glimpses of animals bidden habits is important to scientists, but documentaries like Animals with Cameras also resonate with (引起共鸣)audiences, connecting them with the beauty - and danger - of wildlife in their natural environments," Live Science noted.
