<< Vchera 5.07.2011 Zavtra >>
Treugol'naya ten' bol'shogo vulkana
Avtory i prava: Huan Karlos Kasado (Mir noch'yu)
Perevod: Vol'nova A.A.
Poyasnenie: Pochemu ten' etogo vulkana vyglyadit kak treugol'nik? Sam vulkan Maunt Teide vovse ne imeet takoi pravil'noi treugol'noi formy, kak mozhet pokazat'sya po vidu ego piramidal'noi teni. Odnako, pohozhee yavlenie treugol'nyh tenei harakterno ne tol'ko dlya Maunt Teide. Takoe zrelishe obychno mozhno uvidet' s vershin vseh vysokih gor i vulkanov. Klyuch k razgadke prirody takih neobychnyh tenei prost: nablyudatel', stoyashii na vershine, smotrit skvoz' dlinnyi koridor teni ot zakata (ili voshoda), kotoryi tyanetsya do samogo gorizonta. Dazhe esli by vulkan imel pravil'nuyu kubicheskuyu formu, a ego ten' byla by dlinnym pryamougol'nikom, samyi dal'nii konec etoi pryamougol'noi teni kazalsya by tochkoi. Tak na gorizonte shodyatsya vmeste parallel'nye zheleznodorozhnye rel'sy. Na perednem plane segodnyashnei krasochnoi fotografii viden krater Piko V'eho, raspolozhennyi na ostrove Tenerife arhipelaga Kanarskih ostrovov v Ispanii. Ryadom s zhivopisnoi ten'yu vidna pochti polnaya Luna srazu zhe posle svoego polnogo zatmeniya, kotoroe proizoshlo v proshlom mesyace.
