Today I learned that the 10 Deutsche Mark banknote depicts (prolific) German mathematician, Carl Friedrich Gauss.
Not only that, but the bank note also depicts one of his achievements: the formula and (detailed) graph of the Normal (or Gaussian) Distribution, one of the most important probability distributions.
(Click bank note to see the detail of the formula).
I wonder if a case can be made for understanding what is important to a country by what they put on their money. Canada has hockey players on their 5 dollar bill. Hmmm.....
