Re[n]: "Volshebnye" principy astronomii
10.08.2007 14:20 | Dmitrii Docenko

Uvazhaemyi A.N.! Pozvol'te zadat' vam paru voprosov na vashi citaty.

> No prosto goloslovno zayavlyat', chto plazma Solnca i prochih zvezd odnorodna po himicheskomu sostavu i pochti nezavisit ot glubiny - eto voobshe proizvol!

Kto eto zayavlyaet? Zamechu, chto etot vopros ya zadayu kak minimum vtoroi raz.

> dlya togo chtoby opredelit' kak vliyaet gravitaciya na sostav plazmy neobhodimo proizvesti ekperiment

Dumayu, dlya etogo vam dostatochno budet poznakomitsya s teoriei; eksperiment - vesh' neprostaya. Smile

V lyubom sluchae, zakony izvestny i dostatochno chislennogo eksperimenta. Kstati, kakuyu stepen' neodnorodnosti vy ozhidaete v kamere vysotoi 10 m v plazme temperaturoi 6000 K (kak v fotosfere Solnce)?

> vse eti traktaty eto fil'kina gramota!

Obosnuite, a? (to, chto vy ne ponimaete fiziku zvezd, za obosnovanie ne schitaetsya) Wink

> Mozhet delo v tom chto iz-za nizkoi plotnosti zvezdy ona ne smogla uderzhat' vodorod i gelii i eti legkie elementy prosto uleteli s poverhnosti zvezdy?

Razve tak slozhno ocenit', skol'ko uletit vodoroda s poverhnosti krasnogo giganta za ego vremya zhizni? Prodelaite raschet i otvet stanet ocheviden.

> Ya tak ponimayu, chto v etoi bezkonvekcionnoi vnutrennei chasti [Solnca] vse-taki proizoidet razdelenie plazmy po sostavu pod vozdeistviem gravitacii?

Obosnuite, a? Predpolagat' - eto zdorovo, no ocenite vremya, za kotoroe eto razdelenie proizoidet.

Po moim (grubym) ocenkam skorosti diffuzii za milliard let gelii prodiffundiruet menee, chem na 1% radiusa Solnca.

Zhdu otvetov.

Vy znaete, v shkole ucheniki chasto schitayut, chto dumat' samim ne nuzhno, potomu chto otvety na vse voprosy uchitelya dayut v gotovom vide. V universitete zhe obychno privivaetsya protivopolozhnoe mnenie - esli sam ne podumaesh', to ne poimesh'. Imenno iz-za togo, chto mne blizhe universitet, ya i zadayu vam eti voprosy i nadeyus', chto vy na nih otvetite. Hotya by sebe.
