Edmond Halley: The Man Behind the Comet

This year is 2061. Ordinary astronomy enthusiasts and experienced astrophysicists gather at the darkest and most hidden corners of the globe and witness the return of something closest to the most famous earth in history. Although this famous event dates back to around 239 BC, it is known as the perigee of Halley's comet, but Edmund Ha is responsible for accurately analyzing its recurrence and calculating the trajectory of that 75 year.

In 1680, 24-year-old Edmund Halley (1656 - 1742) found a huge comet. A friend of Isaac Newton who later became a royal astronomer wanted to necessarily run in a straight track as Kepler asked 60 years ago. wastefully! In a meeting with Newton, Halley explained that the comet of 1680 might have a "winding" orbit. Based on this finding, Edmund Halley made a new calculation and apparently moved on an elongated ellipse and found it should return in 1758. Known as Halley's comet, this comet returns to the inner solar system, so all 76 Earths are approaching the Earth. The year, the last year was 1985/86

Future observations of the comet in 1682 eventually will eliminate any lengthy doubt. Newton's friend Edmund Halley began collecting accurate comet observations to compare the orbit of many comets in 1695. Halley noted that between 75 and 76 years, the orbit of some comets seems to resemble the same period at about the same time. "A number of considerations made me believe that the comets observed by Apians in 1531 are the same as the comets described by Kepler ... in 1607, in 1682 I took it again in 1682 "I am predicting that it will come back with confidence, that is, in 1758. If this happens, then other comets should be returned without further doubt." Harley The confidence of the first comet was discovered again on December 25, when it proved to be effective. Since then, it is called Halley's comet

Of course, we need to calculate the risk. You really can not bet on the savings of the life of Halley's comet that you saw in 2020. It is not so, as Edmund Harry proved comets of Harley comet to emerge every 76 years through his calculation. His calculations are all accurate and pretty, they will emerge in 2061. . We are too scared to try to fail. I am afraid to take risks. I am afraid of losing my job, money, telephone and social life. Needless to say F grade, I am afraid to get B or C grade. After succeeding I did not work for it, I hope to realize it someday when we do not have enough power to reach the peak.
