Electrical devices could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. The movements of the walking person push parts of a small machine that produces electricity. Using the device, 22an adult walking quickly could produce thirteen wars of electricity in just a minute. Max says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. 23The device could also be used in hospitals to operate heart pacemakers; it c

When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it—at this moment in time. It appears probable, however, that sunlight will be the color we know for only a small part of the Sun’s history.
Stars, like individuals, age and change. As we look out into space. We see around us stars at all stages of evolution. There are faint bloodred dwarfs school that their surface temperature is a mere 4,000 degrees Fahrenheit, there are searing ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature; today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun’s light is concentrated in the yellow band of the spectrum, falling slowly in
A. The dangers of invisible radiation.

Soon after I graduated from college, I was lucky enough to get a job in a department store. I worked there for three years as a secretary to the manager. Then I was promoted to the position of his assistant. I stayed on that job for another year, but then I got bored and decided to leave. I applied for other jobs in the same area. But I had no luck getting a second job. So in the end, I had to work as a waitress in a restaurant. Well, I wasn’t very successful, because I kept dropping things. After a few weeks, I lost my job again. Then, just by chance, I met an old friend. She found me a job as a television presenter on a program called "Business Today". This is the job I’m now doing. It is very interesting and I love it.
