A Near Perfect Illusioni by Bill Bunting Whcn obscrving the ful moon as it riscs, our senses tell us that the moon is Iwo to tliree limes larget, than it is after il lias risen well abovc thc horizon. There is no rational reason for tbis as thc moon is no dloser ta the observer at moon risc than laler in the evening. As a mnater of fact it is 64,000 kmi (4,000 miles) further from your eye (thc radius of the earth) as it rises-, than it is as it reaches a point dircctly overhcad. If You ever Stoppcd to ralionalize why the moon appears enlarged, you might have atributed it tb thc fact that Uic liglit from the moon, close to thc horizon, sMrikcs the carffi's atmosphere at an oblique angle and therefore has much more "air" 10 penetrale tb bc reccivcd by your eye. This "extra air" might, in some way act as a lens to magnify the moon and make il appear larger. Afler aIl, Uic cxtra distance thc sun's light must travel from the horizon to Our eyc, turns Uic sunsets rcd and shows us a giant rcd disc near Uic horizon, as Uic sun sets. Thic truUi is, this observation is one of nature's m~ost ncarly perfect illusions. Neither Uic Sun nor Uic moon, as iA appears near thc horizon, whcther rising or setting, is any larger than' it is *whcn il is at Uic zeniUi. It is only our senses tbat tel us that il is. Early astronomers recognizcd titis fact and tried to explain iL. An Egyptian astronomer ini Uic first century A.D. suggested Ibat whcn Uic moon is close to Uic horizon, wc sec il along wiUi Uic familiar back drop of trees 'and buildings. Knowing Uic size of Uic backçdrop and how big the moon is, in comparison, wc think we sec it larger than it is. However, this does not explain Uic fact Ibat Uic same phenomenon occurs on Uic dcsert, Or at sca whcrc Uic horizon is dcvoid of objccts of a faiiar size. Tlrials coniductcd a t Universities in Uic United States uscd 20 inch cardboard discs which wcrc shown to people boUi ouldoors (horizon visible) and in a darkened room (no visible horizon). The discs werc displaycd both at cyc level and also clevated in relation to the observers' cycs. The observers wcoe positioned so that Uiey wcre equidistant from the îwo dises. H-owcvcr, Uiey were not told Uic discs were Uic same size. Wben askcd to compare Uic sizes of Uic two discs every one of Uic test subjects said Uic lowcr- disc was the larger. Chldren particularly saw Uic dises as larger (from îwo 10 four limes as large) than did the adults. There seems 10 be somcthing about looking liorizontally at an object that makes us perceive it to be larger than whcn we observe it above thc horizontal. There must be other reasons as wdll but no one lias becn able 10 suggcsî what Uicy miglit bc. Knowing that full will Uic size of Uic moon is not any largcr as it riscs, as well as knowing about Uic trials Uiat have been donc to prove this, 1 sîill sec what cveryonc cIsescsecs whcn I look at Uic rising full moon, and noUing I tell myseif will make me sec it diffcrently. To prove 10 yourself that Uis is an illusion, (better not try this on a main street or whcrc strangers cas sec you), turn your back on the ncwly rising ful moon, bcnd over and look at Uic moon upside down from beîween your legs. It will appear mucli smaller. As a final proof, hold as aspirin tablet, bcîwcen your tliumb and fore finger, at arms lengîli. Position yourself so that Uic aspirin covers Uic full moon. The aspirin will appear just a bit larger than the moon and will nicely cover il whethcr 1the full moon lias just risen or whethcr il is at Uic zenith. Thec same proposition holds truc for die sun, that large red baîl1 you sec just as Uic s un is setting is no larger than the sun you sec at higli noon. Howevcr, il is harder 10 prove Uiat Ibis is so for the sun, since it is not safe 10 look at the1e Sun bo compare sizes. Nature lias many tricks 10 play s on the unwary. However, t11er illusions of a larger than normal, rising or sctting, moon or sun is one of Uic best. r Rare painting returns from Restoration Lab Rare Paint-ing returns from Conserl'ation Lab Restora ion... From October 6 Io Novemnber 22 a rare painting from Uic Clarke, Muscum collection will bc on display at Uic Museum at Kirby.
