**Abstract: **

In the 19th century, it was observed that Mercury's orbit did not follow the planetary laws of motion set forth by Kepler and proved by Newton. In the beginning of the 20th century, Einstein reinvented the laws of gravity with his theory of general relativity. His theory correctly predicts Mercury's orbit - a huge triumph of Einstein's theory. However, Einstein himself struggled with the mathematics of his own theory. It took Hilbert (who later called upon Emmy Noether for help) to show how to use Einstein's theory to predict the correct orbit of Mercury. Noether's Theorem is now a fundamental result in theoretical physics. Apparently, she also did things related to algebra.
