Sirkulong Valeriepieris
An Sirkulong Valeriepieris[1][2][3] iyo an sarong pigura na nakagurit sa ibabaw kan Kinaban siring kan mayorya kan populasyon kan katawohan na nakaistar sa laog kan saiyang interior. Pinabantog an konsepto kan sarong mapa na nakapaskil sa Reddit kaidtong 2013, ginibo kan sarong taga-Texas na paratukdo nin ESL na igwa nin ngaran na Ken Myers, na an ngaran nin paragamit sa sityo tinawan nin ngaran an pigura.[4] An orihinal na sirkulo ni Myers nasasakopan an haros 10% kan kabilugan kan ibabaw kan Kinaban, na igwa nin radius nin haros 4,000 kilometers (2,500 mi), nakasentro sa Dagat Habagatan na Tsina.[1] Nagin bantog an mapa sa meme, asin naitampok sa nagkapirang internet media outlets.[5][6][7] Naggagamit an orihinal na mapa nin Myers nin Winkel tripel projection, nangangahulugan na an saiyang sirkulo, dai na-adjust sa projection, does not correspond sa sarong sirkulo sa ibabaw kan ispiro.[8][9]
Kaidtong 2015, sarong Singaporean professor na si Danny Quah—sa tabang kan sarong intern na nagngangaran na Ken Teoh—bineripika an orihinal na paghingako ni Myers, siring man an pagpresentar nin bagong, konsiderableng sadit na sirkulo na nakasentro sa sarong township kan Mong Khet sa Myanmar, na igwa nin radius nin 3,300 kilometers (2,050 mi).[1] Sa totoo lang, pighingako ni Quah an sirkulong ini na iyo an pinakasadit na posible nanggad, prinodusir gikan sa urog na rigorous calculations asin updated data, siring man an pagigin sarong proper circle sa ibabaw kan Kinaban.
Kaidtong 2022, an orihinal na sirkulo ni Myers sa giraray pinorbaran ni Riaz Shah, sarong professor sa Hult International Business School. Guminamit si Shah nin dai pa nahahaloy na pinublikar na impormasyon kan United Nations' World Population Prospects tanganing tantyahon an 4.2 bilyon katawo na nakaistar sa laog kan sirkulo poon pa kaidtong 2022, sa kabilugan kan populasyon kan katawohan na 8 bilyon.[10]
An Sirkulong Valeriepieris igwa nin mahibog na populasyon, one third kaiyan sarong kadagatan. Dugang pa, kabali sa sirkulo an hararayong mga rehiyon kan Siberia, Mongolia, an pinakamahimpis na populasyon na nasyon, asin an Himalayas.[2]
Ginibong pormal an idea ni Myers[11] asin an Sirkulong Valeriepieris pwedeng iladawan para sa maski arin na ronang espasyo, siring kan saro-saroeng nasyon. An pangkagabsan na sirkulong Valeriepieris na ini pwedeng gamiton para sa pag-adal nin pagbabago kan populasyon sa paglihis kan panahon, dimensional reduction asin pagsukol nin population centralization.
