William Herschell, anne ve babas\u0131n\u0131n deste\u011fini gen\u00e7 ya\u015fta yitirip, kendi ba\u015f\u0131na emek vererek sahip olduklar\u0131n\u0131 elde etmi\u015f biriydi. Onu farkl\u0131 k\u0131lan, sahip oldu\u011fu merak duygusunu, m\u00fcziksel estetik ile birle\u015ftirebilme yetene\u011fiydi. M\u00fczik tarihinde Herschell kadar \u00e7ok y\u00f6nl\u00fc bir besteci var olmad\u0131. \u00d6nemli olan nokta ise, bilimsel a\u00e7\u0131dan \u00e7ok \u00f6nemli ke\u015fifler yaparken h\u00e2l\u00e2 kompozisyonlar \u00fcretip, orkestra y\u00f6netebilecek kadar kendinden emin olabilmesiydi. Bu bak\u0131mdan Herschell, pek \u00e7ok bilimsever ki\u015fiye \u00f6rnek te\u015fkil etmektedir.<\/p>\n
