Fizik Paradokslar\u0131:
\nOlbers Paradoksu
\nBu paradoks, biraz da artronomi ile ilgili.<\/p>\n
Olbers, ara\u015ft\u0131rmalar\u0131 neticesinde, \u015fu fikirlere vard\u0131:
\na) K\u00e2inat\u0131n (uzay\u0131n), ba\u015flang\u0131c\u0131 ve sonu yoktur.
\nb) K\u00e2inat\u0131n bir s\u0131n\u0131r\u0131 yoktur.
\nc) K\u00e2inattaki y\u0131ld\u0131zlar, d\u00fczenli bir \u015fekilde da\u011f\u0131lm\u0131\u015ft\u0131r.
\nd) K\u00e2inat\u0131n b\u00fcy\u00fckl\u00fc\u011f\u00fc sabittir.
\ne) Di\u011fer y\u0131ld\u0131zlardan gelen \u0131\u015f\u0131\u011f\u0131 engelleyici bir fakt\u00f6r yoktur.
\nB\u00fct\u00fcn bunlara dayanarak, Olbers’e g\u00f6re gece g\u00f6ky\u00fcz\u00fcn\u00fcn \u00e7ok parlak olmas\u0131 gerekir. \u00c7\u00fcnk\u00fc sonsuz adet \u0131\u015f\u0131k kayna\u011f\u0131 yani y\u0131ld\u0131z mevcuttur. Gece, karanl\u0131k oldu\u011funa g\u00f6re yanl\u0131\u015f olan bir\u015feyler var. Yap\u0131lan ara\u015ft\u0131rmalar, k\u00e2inat\u0131n bir ba\u015flang\u0131c\u0131 oldu\u011funu ispatlam\u0131\u015ft\u0131r. K\u00e2inat\u0131n saniyede 60 bin km. h\u0131zla geni\u015fledi\u011fi de ilm\u00ee bir ger\u00e7ektir. Y\u0131ld\u0131zlardan gelen \u0131\u015f\u0131\u011f\u0131 engelleyen bir fakt\u00f6r mevcut olsa idi, bu fakt\u00f6r\u00fcn \u0131s\u0131nmas\u0131 ve daha sonra da \u0131\u015f\u0131k kayna\u011f\u0131na d\u00f6n\u00fc\u015fmesi gerekirdi. O halde g\u00f6ky\u00fcz\u00fc gece parlak de\u011filse bunun birka\u00e7 sebebi vard\u0131r:
\na) K\u00e2inat\u0131n mutlaka bir ba\u015flang\u0131c\u0131 vard\u0131r.
\nb) K\u00e2inat\u0131n b\u00fcy\u00fckl\u00fc\u011f\u00fc sabit de\u011fildir. Yani geni\u015fliyor.
\nc) Y\u0131ld\u0131z say\u0131s\u0131 s\u0131n\u0131rl\u0131d\u0131r.
\nd) Y\u0131ld\u0131zlar k\u00e2inatta d\u00fczenli olarak da\u011f\u0131lmam\u0131\u015ft\u0131r.
\nAristodan:
\nKabul edelim ki e\u015fit a\u011f\u0131rl\u0131kta ve \u00f6zellikte iki cismi belli bir y\u00fckseklikten att\u0131\u011f\u0131m\u0131zda ikisi de ayn\u0131 zamanda yere d\u00fc\u015fer. \u015eimdi bu iki cismi birbirine ba\u011flay\u0131p tekrar atal\u0131m. Aristo’ya g\u00f6re bu cisimler daha h\u0131zl\u0131 d\u00fc\u015fmelidir. \u00c7\u00fcnk\u00fc art\u0131k a\u011f\u0131rl\u0131klar\u0131n iki kat\u0131 olan tek bir nesne olmu\u015flard\u0131r. Ya da olay\u0131 bir de \u015f\u00f6yle d\u00fc\u015f\u00fcnelim:
\nA\u011f\u0131rl\u0131klar\u0131 A ve a olan iki cisim d\u00fc\u015f\u00fcnelim. Aristo’ya g\u00f6re daha a\u011f\u0131r olan A, daha h\u0131zl\u0131 d\u00fc\u015fer. H\u0131zlar\u0131na da B ve b diyelim. Bu iki cismi birbirine ba\u011flad\u0131\u011f\u0131m\u0131zda, A, a’y\u0131 kendine yani a\u015fa\u011f\u0131 do\u011fru \u00e7ekecek; a da A’y\u0131 yukar\u0131 do\u011fru \u00e7ekecektir. Bu cisimler, yere B ve b aras\u0131nda bir h\u0131zla yere d\u00fc\u015fmelidir. Ama Aristo der ki:
\n-” Cisimleri birbirine ba\u011flad\u0131\u011f\u0131m\u0131zda a\u011f\u0131r olandan daha a\u011f\u0131r bir cisim elde etmi\u015f oluruz. O halde A’dan daha h\u0131zl\u0131 d\u00fc\u015fmeliler.”
\nAmperler:
\n\u00dc\u00e7 fazl\u0131 da\u011f\u0131t\u0131mda, 2 amper ile 2 amper, d\u00f6rt amper etmez. Yani \u00fc\u00e7gen ba\u011flama motorda:
\n2 amp + 2 amp = 3.4641 amp olur.
\n\u0130kizler:
\nFizikte en \u00f6nemli paradokslardan biride ikizler paradoksudur.
\nBuna g\u00f6re ikiz olan karde\u015flerden biri \u0131\u015f\u0131k h\u0131z\u0131 ile uzaya f\u0131rlat\u0131lsa ve 50 sene sonra d\u00fcnyaya tekrar gelse d\u00fcnyada kalan ikizin ya\u015f\u0131 “x+50”, uzaydan gelenin ya\u015f\u0131 ise “x+50>gelen” olacakt\u0131r. Yani biri ya\u015fl\u0131 biri gen\u00e7 ama bir \u00e7ok bilim \u00e7evresi zamanda b\u00f6yle bir yolculu\u011fun \u0131\u015f\u0131k h\u0131z\u0131na dahi \u00e7\u0131k\u0131lsa m\u00fcmk\u00fcn olmayaca\u011f\u0131n\u0131 iddia eder. \u00c7\u00fcnk\u00fc e\u011fer b\u00f6yle olsa idi \u0131\u015f\u0131k s\u00fcrekli ge\u00e7mi\u015fe yol al\u0131r. Evrende s\u00fcrekli yer de\u011fi\u015ftirmeyen \u0131\u015f\u0131k b\u00fct\u00fcn evreni ayd\u0131nlat\u0131rd\u0131.Fakat atmosferimize \u00e7arpan mezonlar\u0131n 1sn l\u0131k an\u0131, 10 dk gibi ge\u00e7irdikleri ispatlanm\u0131\u015ft\u0131r” <\/p>\n
Renklerin Kar\u0131\u015f\u0131m\u0131:
\nRenklerin kar\u0131\u015f\u0131m\u0131n\u0131 iki \u015fekilde ger\u00e7ekle\u015ftirebiliriz.
\na) Madde (mesel\u00e2 boya) olarak,
\nb) I\u015f\u0131k olarak.
\nA\u015fa\u011f\u0131daki ilk \u015fekilde renkler, madde olarak kar\u0131\u015ft\u0131r\u0131lm\u0131\u015ft\u0131r. Kesi\u015fimlerinde di\u011fer renkler de g\u00f6r\u00fclmektedir. T\u00fcm renklerin kesi\u015fiminden de “S\u0130YAH” elde edilir.
\n\u0130kinci \u015fekilde de \u0131\u015f\u0131k olarak kar\u0131\u015f\u0131m yap\u0131lm\u0131\u015ft\u0131r. Burada da t\u00fcm renklerin kar\u0131\u015f\u0131m\u0131 “BEYAZ”\u0131 verir. (G\u00f6kku\u015fa\u011f\u0131nda veya prizmada oldu\u011fu gibi) <\/p>\n
Akan Su
\nBir muslu\u011fu biraz a\u00e7\u0131p g\u00f6zleyelim. Seri halde akan su, a\u015fa\u011f\u0131 do\u011fru indik\u00e7e inceliyor. Neden?
\n \u0130pucu: Yer\u00e7ekimi ve h\u0131z
\nYa\u011fmur
\n\u00c7ok \u015fiddetli bir ya\u011fmur ya\u011f\u0131yor. Gidece\u011fimiz yere \u0131slanmadan ula\u015fmak i\u00e7in ko\u015fmak iyi bir fikir mi, Yoksa y\u00fcr\u00fcmeli miyiz? S\u00fcre ve mesafe, \u0131slanmay\u0131 nas\u0131l etkiler?
\n \u0130pucu: Mesel\u00e2 10 metrelik bir mesafeyi ve 10 dakikal\u0131k s\u00fcreyi ayr\u0131 ayr\u0131 d\u00fc\u015f\u00fcn\u00fcn.<\/p>\n","protected":false},"excerpt":{"rendered":"
