The NRICH [1] website publishes free mathematics education enrichment material for ages 5 to 19. NRICH material focuses on problem-solving, building core mathematical reasoning and strategic thinking skills. In the academic year 2004/5 the website attracted over 1.7 million site visits (more than 49 million hits).
The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
[1] The examiner was confident that there was one, and only one, correct answer, which is found by measuring the difference in pressure at the top and bottom of the building and solving for height. Contrary to the examiner's expectations, the student responded with a series of completely different answers.
A common and simple version of this problem asks to measure a time of 45 seconds using only two fuses that each burn for a minute. The assumptions of the problem are usually specified in a way that prevents measuring out 3/4 of the length of one fuse and burning it end-to-end, for instance by stating that the fuses burn unevenly along their length.
[23] [24] [25] The WCST was originally developed to measure abstract reasoning [26] as such it may be used to help measure an individual's competence in abstract reasoning, and the ability to change problem-solving strategies when needed. [27] [28] In this test, a number of cards are presented to the participants. The figures on the cards ...
a. If the coins balance, the odd coin is in the population of 5 and proceed to test 2a. b. The odd coin is among the population of 8 coins, proceed in the same way as in the 12 coins problem. 3) Test 2a, Test 3 of the coins from the group of 5 coins against any 3 coins from the population of 8 coins: a.
The Torrance Tests of Creative Thinking, formerly the Minnesota Tests of Creative Thinking, is a test of creativity built on J. P. Guilford's work and created by Ellis Paul Torrance, the Torrance Tests of Creative Thinking originally involved simple tests of divergent thinking and other problem-solving skills, which were scored on four scales ...
The goat problems do not yield any new mathematical insights; rather they are primarily exercises in how to artfully deconstruct problems in order to facilitate solution. Three-dimensional analogues and planar boundary/area problems on other shapes, including the obvious rectangular barn and/or field, have been proposed and solved. [ 1 ]
