Fran\u00e7ois Arago , Arago, Perpignan’da ve 23 ya\u015f\u0131nda Paris’teki \u00c9cole Polytechnique’de, analitik geometri k\u00fcrs\u00fcs\u00fcnde Gaspard Monge<\/a>‘\u0131n yan\u0131nda \u00e7al\u0131\u015fmaya ba\u015flad\u0131. 1803 te\u00a0Paris G\u00f6zlemevi ve Bilimler Akademisi’nin daimi sekreteri ve m\u00fcd\u00fcr\u00fc oldu. Frans\u0131z siyasetinde cumhuriyet\u00e7i olarak da aktif biriydi. 1806\u2019da g\u00f6ky\u00fcz\u00fcyle ilgili g\u00f6zlemler yapmak \u00fczere ispanya ya g\u00f6nderildi.

1820’de, Arago, Orsted’in \u00e7al\u0131\u015fmalar\u0131n\u0131 inceledi ve demir etraf\u0131na sar\u0131lm\u0131\u015f bak\u0131r tellerin g\u00f6nd\u00fc\u011f\u00fcnde m\u0131knat\u0131slanma olu\u015fturdu\u011funu g\u00f6sterdi.\u00a01824’te d\u00f6nen bir bak\u0131r diskin, \u00fczerinde as\u0131l\u0131 bir manyetik i\u011fnede m\u0131knat\u0131slanma olu\u015ftu\u011funu g\u00f6sterdi.\u00a0Michael Faraday<\/a> daha sonra bunun ind\u00fcksiyon olay\u0131 oldu\u011funu kan\u0131tlad\u0131.<\/p>\n

Siyasal ya\u015famda ate\u015fli bir liberal olarak 1830 ve 1848 devrimlerinde \u00f6n s\u0131ralarda yer ald\u0131. 1848 Devrimi’nden sonra ge\u00e7ici h\u00fck\u00fcmette sava\u015f ve deniz bakan\u0131 olarak bir\u00e7ok reform ger\u00e7ekle\u015ftirdi.\u00a0 Kar\u015f\u0131 g\u00f6r\u00fc\u015fte oldu\u011fu Louis Napolyon 1851 de cumhurba\u015fkan\u0131 olunca siyasal ya\u015fam\u0131 sona erdi.<\/p>\n

Arago\u2019nun \u00e7al\u0131\u015fmalar\u0131 genellikle optik ve manyetizma konular\u0131nda oldu. Kimi kristallerin beyaz \u0131\u015f\u0131\u011f\u0131 kutuplad\u0131\u011f\u0131n\u0131 buldu ve dairesel kutuplama olay\u0131n\u0131 tan\u0131mlad\u0131.

Foucault ger\u00e7ekle\u015ftirdi. Oersted in deneylerinden esinlenerek Ampere ile birlikte ge\u00e7ici ve kal\u0131c\u0131 m\u0131knat\u0131sl\u0131k olay\u0131n\u0131 bulu\u015fu ona Londra Royal Society \u201cCopley\u201d madalyas\u0131n\u0131 kazand\u0131rd\u0131.<\/p>\n
