Help in history!?!?! (World War II and I) Few questions i need answering please...!?
WW1 happened because of the expanding imperialist countries. Major countries like France, Austria-Hungary, and England. They all wanted more land and resources to become even more powerful. The Nazi party is the National Socialist Party. They believed in a strong government and promised to turn Germany back into a world power. Communists believe in a form of government called communism. Communism has the idea of equality for all and ownership for all. While this idea sounds great on paper, it will never work because of people's greed. The French and British created the Treaty of Versailles. It was a harsh treaty that forced the Germans to pay reparations to Great Britain and France. Hope this helps. Good luck.
I need an explanation with GMT, EST, UTC, timezone related?
Suppose you are standing on the North Pole, sometime in the summer so that the sun is above the horizon. You see the sun in front of you, and observe it moving to the right. All the meridians merge under your feet, and the sun will cross them in turn, moving fifteen degrees each hour. It will be local solar noon under the sun; as the sun moves, so will noon. It is clear that time, as defined by the sun, will vary from place to place, and that to make time more manageable, a zone system, in which all clocks in a zone would be similarly set, would be useful. The basics of the design are: - There is a prime meridian, against which all other meridians are measured. By convention, it runs through the Naval Observatory in Greenwich, England. - There must be a meridian at which the day begins. At any given time, there must be times at different places belonging to two different days. The boundary, which mostly follows the 180 meridian but has some wiggles for some island groups, is the International Date Line. - The original universal time was Greenwich Mean Time. Because the earth's orbit is not quite circular, the duration of the time between succesive solar noons varies throughout the year. GMT is contrived to flatten the bumps, so that the sun is at the same place at the beginning of each year. It has been supplanted by Universal Coordinated Time, because there are irregularities in the earth's rotation and the desired accuracy can be had only with special clocks, which keep time precisely to a few parts in a trillion. Because the earth's rotation is slowing due to the tides, a leap second is added to the UTC about once a year. The various time zones can be designated by the difference between them and GMT or UTC. Eastern standard time is five hours earlier than GMT, or GMT-5. Pacific Standard Time is GMT-8. Paris and Berlin are on GMT+1. By subraction, we can find that the difference between EST and Paris time is 6 hours.
