Anthony here equates Armstrong's achievement and those who made it possible with photographing the Sun at clock noon and imagining there is a sequence of reasoning which explains the figure 8 - there isn't and some enterprising individuals took it a step further by discovering the origins of that unfortunate assertion - "At the end of the article, there is a link to "The Use of the Analemma from an inset from Bowles's New and Accurate Map of the World (1780)". This refers to the (English) meaning of "analemma" in the 18th century. At that point in time an analemma was an orthographic projection of the sphere --an entirely distinct definition (so the link probably doesn't belong here). This "analemma" could be a carefully drafted drawing or, in fact, a device for calculation, like a graphical slide rule. These "analemmas" were used to get approximate solutions to the various problems of spherical trigonometry. Only after c.1800, globe makers began placing charts of the Sun's declination on globes and labeling these as analemmas. These are the origin of the modern usage of the word analemma. Also many of these early analemmas did not include the graphing of the equation of time hence they were oval instead of "figure 8" shaped. This is described well in most early 19th century guides to the "use of globes". For example in Keith's "New Treatise on the Use of Globes" published in New York in 1819, you will find "The analemma is properly an orthographic projection of the sphere on the plane of the meridian; but what is called the analemma on the globe, is a narrow slip of paper, the length of which is equal to the breadth of the torrid zone. It is pasted on some vacant place on the globe in the torrid zone, and is divided into months, and days of the months, correspondent to the sun's declination for every day in the year. It is divided into two parts; the right hand part begins at the winter solstice, or December 21st, and is reckoned upwards towards the summer solstice, or June 21st, where the left hand part begins, which is reckoned downwards in a similar manner, or towards the winter solstice. On Cary's globes the Analemma somewhat resembles the figure 8. It appears to have been drawn in this shape for the convenience of showing the equation of time, by means of a straight line which passes through the middle of it. The equation of time is placed on the horizon of Rardin's globes." http://en.wikipedia.org/wiki/Talk:Analemma It is these silly analemmas which are preventing the reasons why the equation of time is necessary and what it refers to or perhaps closer to the truth,the lack of genuine astronomers who can put the variations in natural noon in context of a moving Earth and none of it requires declination,it requires only the assumption that daily and orbital motions are distinct with their own properties.Maybe Anthony represents his nation in losing their astronomical heritage but I assume there are Greek people who actually value the clear distinctions the Greek astronomers once made between the wandering planets and the non-wandering Sun. What's your story ?. |

Well, M57 is certainly a nebulous object, but M56, being a globular cluster, is not at all nebulous, unless viewed through a very small instrument. All astronomical objects are best viewed when directly overhead, and with Vega and other delights in the Lyre being located at about 38 to 39 degrees north declination, Alaska would NOT be a superior location from which to view them. Athens, after all is at about 38 degrees north latitude, and Lyra passes essentially directly overhead for Anthony. His problem is that the nights are too short there in the summer to view an entire cycle in one night. In Alaska, the summer nights would be even shorter and RR Lyra would be even farther from Zenith... \Paul A |

As for the kind offer involving the use of the remote facilities at Arizona, there is no question it is something I plan to follow-up with very keen interest. Anthony. |
