In order to use the sundial, the block is put horizontally where the long sides correspond to the North-South direction, and the short sides correspond to the East-West direction. At sunrise in the morning, the shadow of the eastern block edge falls onto the leading edge of the topmost step of the stairs, which rises from the east. graduation. In his own work, Rimmer cited an 1890 book as his proof of the calculations behind the tale. They read the Bible and there it was "about (approximately) a day" These little words in the Bible are important, but they were still in trouble because if you cannot account for 40 minutes you'll still be in trouble 1,000 years from now. That's right "The sun stood still and the moon stayed and hasted not to go down about a whole day!" An Egyptian obelisk constructed c.3500 BC,[16] a gnomon in China dated 2300 BC,[17] and an Egyptian sundial dated 1500 BC[18] are some of the earliest methods for measuring the sun's position.

To mark the time on the dial, use the protractor again, and lining 90 degrees with noon, each hour on either side will be 15 degrees apart, so that 6am and 6pm will be both perpendicular to noon. Many ornamental sundials are designed to be used at 45 degrees north. Some mass-produced garden sundials fail to correctly calculate the hourlines and so can never be corrected. A local standard time zone is nominally 15 degrees wide, but may be modified to follow geographic or political boundaries. Dept., Harvard) Journal for the History of Astronomy Vol. B. Eerdmans, 1936 (pp. The difference between this corrected mean solar time and Coordinated Universal Time (UTC) determines whether a leap second is needed. As it turns out, the "23 hours and 20 minutes" figure was almost certainly an amount of time chosen by the legend's originator for extra-scriptual reasons we'll explain later. For a sundial in Jerusalem at 31 north-latitude, the sundial must be inclined 13. Figure 8. 10 degrees that God moved the shadow backwards x 4 minutes per degree = 40 minutes! I was already a teacher by profession and I was searching for some B.Ed. Thus, another atheistic charge against the biblical narrative bites the dust, yet again.

The Egyptians used a sundial to tell time during the day and a water clock at night. Flammarion suggested that a manipulated inclined plane is necessary to show the retro-gradation of the shadow. In each such zone, sundial time matches clock time at only one geographical longitude: elsewhere a correction must be added, proportional to the difference in longitude from the locations where sundial time is exact. This was influenced from Pedro Nunes (a Portuguese mathematician in the 1500s), since he was the first scientist that described this phenomenon of retro-gradation and related it to the sundial in 2 Kings 20:8-11.
