This article provides a solution in the R language for Euler Problem 144: How many times does a laser bounce inside an elliptical mirror before the light beam exits it? We can use the solution to this problem to simulate elliptical billiard tables.
Euler Problem 32 returns to pandigital numbers, which are numbers that contain one of each digit. Like so many of the Euler Problems, these numbers serve no practical purpose whatsoever, other than some entertainment value. You can find all pandigital… Continue Reading →
