It is born in a family of laborers, the mother daughter of peasants and second moglie of the father who  was to giardiniere. In the 1792 it was enrolled to the Collegium Carolinum, that   then it would have become Gauss in the 1803 Techinische Hochschule di Braunschweig. The professor and. To W. Zimmerman made so that Gauss obtained one pension from duca the Carl Wilhelm Ferdinand that said the possibility to Gauss to continue the studies until to the university. In the 1795 Gauss it began  the university studies to the faculty of Göttingen.  30 March 1796 succeeded to construct to a regular polygon of 17 sides with line and calipers. In this decided occasion he   definitively for the mathematics studies, in spite of its alive interest for the ancient languages. In 1799 it obtained the doctorate to the university of Helmstedt, with one extraordinary containing dissertation the first exact demonstration   of the fundamental theorem of algebra.

1801 mark two extraordinary events,  the publication of " Disquisitiones arithmetucae" and the calculation of the orbit of the asteroid Cerere (Ceres) observed from, G. Public squares in January of the same year. 9 October 1805 Gauss married Johanna Osthoff, of Braunschweig from which it had one son and one daughter  . Their happy union however was interrupted in 1809 from birth of   the third son who caused the dead women of the mother. In 1806, to the dead women of the duca of Braunschweig, in spite of its natural aversion for the instruction, it accepted the assignment of director   of the astronomical Observatory and ordinary of astronomy to the university of Göttingen, that it maintained until death. Risposa in 1810 with the best friend of the moglie Minna Waldeck from this new union a male and one will be born themselves female (Teresa). In 1816 he was person in charge to carry out the geodetic measurements of the reign of Hannover, of which it made Göttingen part. In this occasion he invented the eliotropo, an optical telegraph; he developed geometry he differentiates them and he constructed   a theory for the elimination of the errors in the calculation. The measurement lasted in all venticinque years. In 1821 to Berlin, in occasion of  a conference of the scientists and the German doctors, Gauss knew the still young W physicist. And Weber that Gauss made to call to Göttingen. Between the two one was settled down   exceptionally fecund collaboration in the study of the electromagnetic phenomena and the land magnetism. 

1831 die the second moglie Minna Waldeck. The daughter Teresa will take the redini of the domestic life.  In 1833 they they constructed a first electromagnetic telegraph, that it connected the observatory to the Institute of physics of Göttingen. From their collaboration the system of physical measures absolute (known like c.g.s gushed today.  electrostatic and c.g.s.  electromagnetic) that Gauss proposed to the public in 1832.

After the 1850 Gauss accusation it disturbs to the heart, disease that will limit on the scientific engagements. It dies in the sleep in February 1855.In 1855 it the acknowledgment "Princeps was conferredmathematicorum". Its works are exited in twelve volumes  to Göttingen between 1863 and 1933.

Gauss is the c.g.s. unit (symbol Gs) of magnetic induction or magnetic flux density, replaced by the unit, the tesla, but still commonly used. It is equal to one linens of magnetic flux for square centimetre. The Earth' s magnetic field is about 0,5 Gs, and changes to it over Time to are measured in gammas (one range equals 10-5 gauss).
