Gauss was born in Brunswick. 1796, Gauss discovered the regular drawing of regular heptagon. 1807, Gauss became a professor at the University of G? ttingen and director of the G? ttingen Observatory. During the period of1818-1826, the geodetic work in hanover principality was mainly Gaussian. 1840, gauss and Weber drew the world's first map of the earth's magnetic field.
Introduction to Gauss's achievements:
Gauss summed up the application of complex numbers and strictly proved that every algebraic equation of order n must have n real numbers or complex numbers. In his first masterpiece, Arithmetic Research, he proved the law of quadratic reciprocity, which became an important basis for the continued development of number theory. The first chapter of this book deduces the concept of triangle congruence theorem.
With the help of Gaussian survey adjustment theory based on least square method, the trajectory of celestial bodies is calculated. In this way, he calculated the trajectory of the asteroid Ceres.
