Ludwig Diels




Friedrich Ludwig Emil Diels, född 24 september 1874 i Hamburg, död 30 november 1945 i Berlin, var en tysk botaniker. Han var son till filologen Hermann Diels.


Diels blev 1896 assistent vid Berlins botaniska museum, 1900 docent i Berlin, 1908 professor i botanik i Marburg, underdirektor för Berlins botaniska trädgård och museum (Dahlem) 1913 och direktor där 1921. Han företog 1900-02 resor till bland annat Kaplandet, Australien och Java. Han invaldes som utländsk ledamot av Kungliga Vetenskapsakademien 1933. Hans botaniska samlingar förstördes i ett bombangrepp på Berlin 1943.

An IMO inspired problem

Image
14 4 This problem from IMO 1988 is said to be one of the most elegant ones in functional equations. Problem : The function $f$ is defined on the set of all positive integers as follows: begin{align} f(1) = 1, f(3) &= 3, f(2n) = f(n), \ f(4n+1) &= 2f(2n+1) - f(n), \ f(4n+3) &= 3 f(2n+1) - 2f(n) end{align} Find the number of $n$ with $f(n) = n, 1 leq n leq 1988$. The main idea towards the solution is realizing that these conditions stand for the fact that $f(n)$ just reverses the digits in the binary representation of the number $n$. So, essentially the solution is finding the number of binary pallindromes $leq 1988_{10}$. My question is the following : How to reformulate the problem so that $f(n)$ reverses the digits of $n$ in its ternary representation. Or even better, can we reformulate it for a

Has there ever been an instance of an active nuclear power plant within or near a war zone?

Image
36 3 The question Has there ever been a military combat going on around an active (running or in outage but not decommissioned) commercial nuclear power plant? Or dangerously near it? If yes, how did the plant and its personnel fare in such situation? Why I ask Let's assume for the scope of this question modern commercial nuclear power plants (CANDU, PWR, BWR of generation II plus all of gen III and newer) are usually reasonably safe to operate given that the engineering has been done right and there is a whole cohort of very well trained personnel on-site at all times, well rested and with considerable resources on their hands. Things hard to get with an armed conflict like the recent Syrian war raging around. I can't seem to find any reference or a comprehensive article about this, hence this question.
