Applications of the harmonic series and its partial sums include Euler's proof that there are infinitely many prime numbers, the analysis of the coupon collector's problem on how many random trials are needed to provide a complete range of responses, the connected components of random graphs, the block-stacking problem on how far over the edge ...
Every September since 1998 retailers and shoppers have celebrated National Coupon Month and this year to mark the occasion one of our favorite coupon collectors, Coupon Sherpa, has launched I Love ...
Canadian Tire money, officially Canadian Tire 'money' [1] [2] or CTM, is a loyalty program operated by the Canadian retail chain Canadian Tire Corporation (CTC).

It serves as a way for license plate collectors to trade plates, distribute news, and ...
Component (graph theory) In graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets. A graph that is itself connected has exactly one component, consisting of the ...
Background. A coin show is an event where coin collectors and coin dealers attend to buy, trade and sell coins. [1] Like other hobby shows, a show hall is arranged with aisles and tables where coin sellers can display their coins. In cities across the United States there are thirty to fifty smaller local shows each weekend.
