it's just a try ... you may find some mistakes...correct them please : Our mother :The earth !
the earth...that floor that we have playing on it since our early age , its benefits can't be countful , but the new technology is hurting it moor & moor every sigle day by the household and industrial wastes that the earth gets by our actions... If i were a friend of the earth ... i wouldn't cause of this horrible things that hurt my friend ... or at less i would try to convince people anbout how dangers this could be ... i would also use the Modified techniques of wastes to Reduce the seriousness of the situation , ... besides , the Recycling is a very good way to Maintain a balance between consumers and synthetic environment... |

اقتباس:
Albert Einstein 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect"The latter was pivotal in establishing quantum theory within physics Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.. |
