Sevgili Fizik \u00f6\u011fretmenim Ertu\u011frul Co\u015fkuner pek an\u0131msam\u0131yor ama birlikte gayet g\u00fczel deneyler kazand\u0131rm\u0131\u015ft\u0131k lisemizin Fizik Laboratuvar\u0131na. Bunlardan biri Atwood Makinesi idi. (*) Bir di\u011feri de batarken G\u00fcne\u015f\u2019in ni\u00e7in k\u0131z\u0131la \u00e7ald\u0131\u011f\u0131na ili\u015fkindi. Cam bir kutu havuz i\u00e7inden ge\u00e7en beyaz \u0131\u015f\u0131k, sudaki k\u00fck\u00fcrt yo\u011funlu\u011fu artt\u0131k\u00e7a k\u0131z\u0131lla\u015fmaktayd\u0131.
\nErtu\u011frul \u00f6\u011fretmenimin amcas\u0131, Erkek Lisesi\u2019nde Felsefe \u00d6\u011fretmeni idi. Bir kez kar\u015f\u0131la\u015ft\u0131k, tan\u0131\u015ft\u0131k. \u015eu fikri gayet filozof\u00e7a idi; \u201cTeknolojik ara\u00e7 gere\u00e7 edindi\u011fimizde, \u00f6rne\u011fin eve buzdolab\u0131 ald\u0131\u011f\u0131m\u0131zda (**) buz dolab\u0131 yap\u0131l\u0131rken yararlan\u0131lan bilim ve teknolojiyi de evimize sokmu\u015f olmuyoruz.\u201d<\/p>\n
ODT\u00dc\u2019ye girince fark ettim ki, bilimsel d\u00fc\u015f\u00fcnceyi kavramak hayli m\u00fc\u015fk\u00fcl bir zenaat idi.<\/p>\n
Kolonya Suyu (***) d\u00f6k\u00fcnerek bir nebze olsun serinlemek modern so\u011futucular\u0131n dayand\u0131\u011f\u0131 temel fikir olmas\u0131na kar\u015f\u0131n, bu ilinti pek bilinmez.
\nBol makaleli bir hocama sordu\u011fum \u015fu iki soruya verdi\u011fi yan\u0131tlar kula\u011f\u0131mda \u00e7\u0131nlar halen:
\ni- Bir fizik olgusuna ili\u015fkin ka\u00e7 deney yapmal\u0131y\u0131z ki, bu olgunun yasa oldu\u011fu sonucuna varabilelim?
\nDemi\u015fti ki, \u201c\u2014Psikolojik olarak tatmin olana kadar.\u201d
\n\u0130kinci sorum ise, bu blogdaki birka\u00e7 yaz\u0131da da de\u011findi\u011fimiz Karacisim I\u015f\u0131mas\u0131 konusunda beklenmedik bulgu, asl\u0131nda ekmek, pasta f\u0131r\u0131nlar\u0131ndan s\u0131zan \u0131\u015f\u0131man\u0131n incelenmesiyle ke\u015ffedilmi\u015fti. Bu nedenle, i\u015fin ba\u015f\u0131nda \u2018Cavity Radiation\u2019 olarak an\u0131l\u0131rd\u0131. (#) Ben de hinlik edip ayn\u0131 hocaya \u015funu sormu\u015ftum.
\nii- \u2018Cavity\u2019 bo\u015flu\u011funu doldurup \u00e7evresindeki maddeyi yok etsek elde edece\u011fimiz bu k\u00fcre de \u2018Cavity Radiation\u2019 yayar m\u0131?
\nDikkatinize arz edeyim ki, kitaplarda ilgili \u015fekillerde \u2018cavity\u2019 hep k\u00fcresel olarak tasvir edilir. Neyse, ayn\u0131 hocam dedi idi ki, \u201c\u2014Hi\u00e7 olur mu \u00f6yle \u015fey?! Ad\u0131 \u00fcst\u00fcnde, \u2018Cavity Radiation\u2019 de\u011fil mi?\u201d
\nTabii ki, kar\u015f\u0131l\u0131k vermedim, veremedim, veremezdim. Ama dersimi alm\u0131\u015ft\u0131m. Diploma, makale sahibi olmak Fizik\u00e7i olmaya yetmeyebiliyordu.<\/p>\n
Yahut, be\u015fer (bazen) \u015fa\u015f\u0131yordu!<\/p>\n
\u00d6rne\u011fim, bu sat\u0131rlar\u0131n yazan\u0131 da \u015fimdiye dek bir hayli gaf yapm\u0131\u015f olmal\u0131. Bu gaflardan (hata, yanl\u0131\u015fl\u0131k dense de olur) biri bu blogun 11. NOT\u2019unda mevcut. (##)
\nBu blogun 11.
