\nYine ihtimaldir ki, deneysel veriye yukar\u0131daki kadar geni\u015f ve hassas uyum dergi edit\u00f6rlerinde makalenin de\u011feri hakk\u0131nda ku\u015fkuya (belki de tam tersi, emin olmaya (!?) ) yol a\u00e7m\u0131\u015ft\u0131r.<\/p>\n

Unutmadan, bir de Einstein Form\u00fcl\u00fc\u2019n\u00fcn i\u015fe yarad\u0131\u011f\u0131 \u00f6rneklerle, yani y\u00fcksek s\u0131cakl\u0131klarda k\u0131yaslama yapmakta yarar var. Elmas ve G\u00fcm\u00fc\u015f se\u00e7ilme nedeni ilkinin yal\u0131tkan ikincinin iletken olu\u015fudur ve Einstein form\u00fcl\u00fc ile uyum (ba\u015fka k\u0131yaslamalarla da desteklendi\u011fi gibi) yal\u0131tkanlarda iletkenlere k\u0131yasla daha iyidir. Bu ge\u00e7e\u011fin alt\u0131ndaki mekanizma ise, a\u00e7\u0131k\u00e7a iletkenlikle yak\u0131ndan ilintilidir.<\/p>\n
