How it’s hard, almost impossible to imagine the size of things in macroworld around us and the hidden microworld within, to understand and compare such things as a millionth part of second in our world and fantastic numbers light years in the universe. Neither microscopes nor telescopes can help us to get the idea about. For example the center of the Milky Way is placed at about 26.100 light years. What is a light year? A light-year is measurement of distance, not of time, that light can travel in one year. Light moves at a velocity of about 300,000 kilometers each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers. And the distance to the next nearest big galaxy, the Andromeda Galaxy, is 21 quintillion km. That’s 21,000,000,000,000,000,000 km. What is the human’s mission in that endlessness?
Just the universe and light of the stars comes through me.
France became the first country to open it’s files on UFO, AFP reported. That secret files been covering 50 years. “The online archives, which will be updated as new cases are reported, catalogues in minute detail cases ranging from the easily dismissed to a handful that continue to perplex even hard-nosed scientists. Known as OVNIs in French, UFOs have always enerated intense interest along with countless conspiracy theories about secretive government cover-ups of findings deemed too sensitive or alarming for public consumption”.
“Our association received some 150 reports from eye-witnesses, and we also got a video shot during this night by two young video amateurs “, he added. “The engine looked like a large triangle with rounded edges, and one of its angles was directed towards the flight path. It had two red lights in the back and a large white one in the front. These lights were not blinkin g. Condensation traces were visible at the rear of the UFO which flew at an altitude estimated to 500 m”.
Electric cars could help ween our dependence on foreign oil. No gas in the car of the future. An electric motor has a lot of torque and you generally don’t have a gear shift involved. They can accelerate quickly and the radio, air conditioning, and styling can be just as sophisticated as today’s gasoline-powered cars.
It is no secret that we live in an unthinkable historical period now. The time of unprecedented technological progress brought us not only supercomputers, genetic engineering, fiber optics, robots, etc, but such small required things as self-cooled beer or artificial retinas of the eye. All of those achievements of science and engineering were opened owing to the modern methods of preservation and transfering of energy. It’s funny but only lazy one is not familiar with Albert Einstein’s famous equation E=mc2, that is an equivalence between mass and energy. I think bombs were not what Einstein had in mind when he published this equation, besides, as we see, atom energy is not panacea at all. So, chemists, physicists, materials scientists and electrical engineers are looking for new ways of sources of energy to improve the environment and reduce dependence on destructive atom, oil and other fossil fuels. What’s good for the planet is also what’s good for humanity.
