||1830: 1830 In a letter to Laplace, Gauss writes about a "curious problem" that he had been working on for twelve years.  He gives the limiting value of  the frequency of distribution of positive integers in the continued fraction of a random number (now called the Gauss-Kuzmin Distribution) as log2(1+x) . He then asks if Laplace can offer help in finding the error term. *Math World https://pballew.blogspot.com/2019/01/on-this-day-in-math-january-30.html
