Q: Article: The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research There are people who claim that SPS is unrealistic - because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple. Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further. We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades - such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy.

Q: Article: There is no doubt eCommerce is growing, and it will continue to grow. However, physical stores would not die as a result of the rise of eCommerce, at least not in the near future. The idea that eCommerce is taking over physical stores has already misguided many people. Physical stores are far from vanishing, and there are some solid reasons for it. The _ for online spending is optimistic with $150 billion expected to be spent in the coming three years, yet we are also expecting $300 billion in spending at physical stores in the same duration. Do you still think that physical-store shopping is too small to sustain the eCommerce blow? Even though consumers are staying away from physical stores that follow older concepts, yet we are seeing the rise of fresh concept stores all around the US. We are seeing innovative and attractive success stories of physical stores, ranging from clothes stores to restaurants to health spas. It would be easy to assume that this trend will continue. Indeed, many shopping malls are dying, yet there are still those shopping centers that are performing well. You can see this for yourself by visiting shopping malls near you. What I want to emphasize here is that not all shopping centers are made equal, just like not all eCommerce retailers are made equal. Both shopping malls and eCommerce sites can lose business if they fail to maintain productivity through improvements and innovations. When you visit shopping centers that are serious about their business, you would see their shops and parking lots packed. On the other hand, even e-tailers like Amazon have experimented with pop-up shopping concepts. It is important to bear in mind that consumers prefer face-to-face interactions instead of online interactions during shopping, meaning that physical stores are going to stay there. Still, eCommerce retailers are seeing all of their excitement disappear as they settle the sales tax problem associated with e-tailing. As of now, five states of America have already imposed sales tax on purchases through eCommerce sites, and e-tailers in those states have already witnessed 6 to 12 percent decrease in sales. This reinforces the fact that physical stores are here to stay, and if you are still undervaluing their growth, you are omitting a huge chunk of the retail representation.
Answer: Fresh concepts help build good business.

Q: Article: The Body Temperature The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer when your are sick. The body keeps the same temperature all the time ,because it balances the heat it produces and it gives off. It is always burning up food and , producing heat. It can produce heat faster when it needs to give off heat than when it becomes too warm. Let's see how this happen. The heat of your body is given off mainly through the skin. When you are cold, your skin is tight and shows "good flesh". When you get chilly, you must dance around to keep warm or else you will shiver. Then your muscles begin to work, burn up fuel, and produce more heat. It is not pleasant to shiver, so you usually prefer to warm up by exercise, or put on more clothes to keep heat in. When you are warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat ,and more body heat is used in evaporating the moisture from your skin. You wear less clothing, too, in warm weather or warm room, so that warm can be given off freely. You feel less like exercising because your body is warm already, and the extra heat produced by exercise makes you uncomfortable. You can see from the way you feel differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to play.
Answer: The Body Temperature Should Always Be the Same
