bandwidth. The first generation of submarine fiber optic cables carried 280 megabits per second‚ compared with only 2.5 megabits per second through copper cables. Modern optical fibers can carry terabits‚ or millions of megabits‚ per second. Electromagnetism Copper cables are inherently vulnerable to electromagnetic interference. Although fiber optic lines do have metallic components‚ these do not carry the signal‚ so interference is not a problem. Copper cables can also be "tapped" electromagnetically

haunt her. When she was 38‚ she committed suicide by taking an overdose of sleeping pills. On the other hand‚ we have the example of Karl Friedrich Gauss‚ who is noted for his wide-ranging contributions to physics‚ particularly the study of electromagnetism. Gauss’ mother had been teaching him numbers at the age of two. His father had played calculation games with him. Furthermore‚ Gauss had an educated uncle who taught him sophisticated math at an early age. But how can parents teach their children

The speed of light (meaning speed of light in vacuum)‚ usually denoted by c‚ is a physical constant important in many areas of physics. Its value is 299‚792‚458 metres per second‚ a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[2] This speed is approximately 186‚282 miles per second. It is the maximum speed at which all energy‚ matter‚ and information in the universe can travel. It is the speed of all massless particles and

THIS ARTICLE IS UNDER RE-CONSTRUCTION (10/18/97) (Suggestions are appreciated) INTRODUCTION In this article‚ Classical Electromagnetism will be defined in terms of two topological statements or postulates: the existence of a non-exact global 1-form of potentials‚ A‚ and the existence of a global exact N-1 form of charge currents‚ J. Then‚ the ideas implied by these topological

go from (non-constant) rates of change to the total change or vice versa‚ and many times in studying a problem we know one and are trying to find the other. Physics makes particular use of calculus; all concepts in classical mechanics and electromagnetism are interrelated through calculus. The mass of an object of known density‚ the moment of inertia of objects‚ as well as the total energy of an object within a conservative field can be found by the use of calculus. An example of the use of calculus

popoasdfghjklhjv xcvbnm yfkhfhjg fghjf ghjf ghf gTheory is a contemplative and rational type of abstract or generalizing thinking‚ or the results of such thinking. Depending on the context‚ the results might for example include generalized explanations of how nature works. The word has its roots in ancient Greek‚ but in modern use it has taken on several different related meanings. A theory is not the same as a hypothesis. A theory provides an explanatory framework for some observation‚ and from
