Dr. Emmy Noether was born on this day in 1882. When she died, Albert Einstein wrote in the _New York Times_ that she was widely considered to be the greatest female mathematician who had ever lived. Image Noether earned her PhD in 1907, one of only 2 women at the U. of Erlangen at that time. After graduating, she taught at the Math Inst. of Erlangen for 7 years without being paid or having a title. She also occasionally taught her father’s classes when he wasn’t feeling well.

Today's #dailymaths CHALLENGE PROBLEM. Problems are taken from the Mathematics 2020 calendar. Each day's problem is posted at 2am Eastern/7am London. Previous day's solution is added a few hours later. Guest mathematician posts welcome; DM if interested! Yesterday's problem with a special series of answers! The answer is as simple as checking a list of the ten problems Hilbert revealed on August 8, and seeing that the Riemann is #8. But what about those problems? Why are they so special, and what do they mean? Keep reading!
