Tinkertoy
The Tinkertoy Construction Set is a toy construction set for children. It was designed in 1914—six years after the Frank Hornby's Meccano sets—by Charles H. Pajeau, who formed the Toy Tinker Company in Evanston, Illinois to manufacture them. Pajeau, a stonemason, designed the toy after seeing children play with sticks and empty spools of thread. Pajeau partnered with Robert Pettit and Gordon Tinker to market a toy that would allow and inspire children to use their imaginations. After an initially-slow start, over a million were sold. The cornerstone of the set is a wooden spool roughly two inches (5 cm) in diameter, with holes drilled every 45 degrees around the perimeter and one through the center. Unlike the center, the perimeter holes do not go all the way through. With the differing-length sticks, the set was intended to be based on the Pythagorean progressive right triangle. The sets were introduced to the public through displays in and around Chicago which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tic-tac-toe
Tic-tac-toe (American English), noughts and crosses (Commonwealth English), or Xs and Os (Canadian or Irish English) is a paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with ''X'' or ''O''. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner. It is a solved game, with a forced draw assuming best play from both players. Gameplay Tic-tac-toe is played on a three-by-three grid by two players, who alternately place the marks X and O in one of the nine spaces in the grid. In the following example, the first player (''X'') wins the game in seven steps: There is no universally-agreed rule as to who plays first, but in this article the convention that X plays first is used. Players soon discover that the best play from both parties leads to a draw. Hence, tic-tac-toe is often played by young children who may not have discovered the optimal strategy. Because of t ...

National Toy Hall Of Fame
The National Toy Hall of Fame is a U.S. hall of fame that recognizes the contributions of toys and games that have sustained their popularity for many years. Criteria for induction include: icon status (the toy is widely recognized, respected, and remembered); longevity (more than a passing fad); discovery (fosters learning, creativity, or discovery); and innovation (profoundly changed play or toy design). Established in 1998 under the direction of Ed Sobey, it was originally housed at A. C. Gilbert's Discovery Village in Salem, Oregon, United States, but was moved to the Strong National Museum of Play (now The Strong) in Rochester, New York, in 2002 after it outgrew its original home. Seventy-eight toys have been enshrined in the National Toy Hall of Fame: Original inductees (1998-99) 2000s Class of 2000 Class of 2001 Class of 2002 Class of 2003 Class of 2004 Class of 2005 Class of 2006 Class of 2007 Class of 2008 The following toys were added in 2008: #The ...

Construction Set
A construction set is a set of standardized pieces that allow for the construction of a variety of different models. The pieces avoid the lead-time of manufacturing custom pieces, and of requiring special training or design time to construct complex systems. This makes them suitable for temporary structures, or for use as children's toys. One very popular brand is Lego. Categories Construction sets can be categorized according to their connection method and geometry: * Struts of variable length that are connected to any point along another strut, and at nodes. ** Tesseract connection points are initially flexible but can be made rigid with the addition of clips. * Struts of fixed but multiple lengths that are connected by nodes are good for building space frames, and often have components that allow full rotational freedom. ** D8h (*228) nodes are used for K'Nex, Tinkertoys, Playskool Pipeworks, Cleversticks and interlocking disks in general. ** D6h nodes are used for ...

Evanston, Illinois
Evanston ( ) is a city, suburb of Chicago. Located in Cook County, Illinois, United States, it is situated on the North Shore along Lake Michigan. Evanston is north of Downtown Chicago, bordered by Chicago to the south, Skokie to the west, Wilmette to the north, and Lake Michigan to the east. Evanston had a population of 78,110 . Founded by Methodist business leaders in 1857, the city was incorporated in 1863. Evanston is home to Northwestern University, founded in 1851 before the city's incorporation, one of the world's leading research universities. Today known for its socially liberal politics and ethnically diverse population, Evanston was historically a dry city, until 1972. The city uses a council–manager system of government and is a Democratic stronghold. The city is heavily shaped by the influence of Chicago, externally, and Northwestern, internally. The city and the university share a historically complex long-standing relationship. History Prior to the 183 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery use ...

Isosceles Right Triangle
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio. Knowing the relationships of the angles or ratios of sides of these special right triangles allows one to quickly calculate various lengths in geometric problems without resorting to more advanced methods. Angle-based "Angle-based" special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or radians, is equal to the sum of the other two angles. ...
