The outer coin makes two rotations rolling once around the inner coin. The path of a single point on the edge of the moving coin is a cardioid.. The coin rotation paradox is the counter-intuitive math problem that, when one coin is rolled around the rim of another coin of equal size, the moving coin completes not one but two full rotations after going all the way around the stationary coin ...
Multiple points on a line imply multiple possible combinations (blue). Only lines with n = 1 or 3 have no points (red). In mathematics , the coin problem (also referred to as the Frobenius coin problem or Frobenius problem , after the mathematician Ferdinand Frobenius ) is a mathematical problem that asks for the largest monetary amount that ...
Visual representation of the Zeckendorf representations of each number (a row of the image) as a sum of Fibonacci numbers (the widths of rectangles intersecting that row). An optimal strategy in Fibonacci nim removes the smallest rectangle in the row for the current pile of coins, leaving a pile described by the remaining rectangles from that row.
Nim is a mathematical game of strategy in which two players take turns removing (or "nimming") objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap or pile.

Coins in a fountain is a problem in combinatorial mathematics that involves a generating function.In this problem, a fountain is an arrangement of non-overlapping unit circles into horizontal rows in the plane so that consecutive circles in the bottom row are tangent to each other, and such that each circle in a higher row is tangent to two coins from the next row below it.
Multiple major wildfires still rage around Los Angeles, forcing tens of thousands of people to evacuate, threatening thousands of structures and leading to a still unknown number of deaths and ...
