Puck Puzzle
The Puck puzzle ( Hungarian: ''Kép Korong''), also known as Picture Disc, is a combination puzzle invented in 1980 by Hungarian physicist András Végh. The disc shaped puzzle consists of 2 central pieces: the inner disc, and segments forming a ring around the inner disc. The number of segments is an even number, most commonly six, eight, or twelve. The outer ring can be rotated around the central disc, similar to a wheel being rotated around its axis An axis (plural ''axes'') is an imaginary line around which an object rotates or is symmetrical. Axis may also refer to: Mathematics * Axis of rotation: see rotation around a fixed axis * Axis (mathematics), a designator for a Cartesian-coordinat .... The two parts of the central disc can also be rotated, together with the attached ring. With these operations, the combination of the parts can be changed. The goal of the game is to obtain a specific combination, such as forming a picture or ordering a sequence of numbers on the segm ...

Combination Puzzle
A combination puzzle, also known as a sequential move puzzle, is a puzzle which consists of a set of pieces which can be manipulated into different combinations by a group of operations. Many such puzzles are mechanical puzzles of polyhedral shape, consisting of multiple layers of pieces along each axis which can rotate independently of each other. Collectively known as twisty puzzles, the archetype of this kind of puzzle is the Rubik's Cube. Each rotating side is usually marked with different colours, intended to be scrambled, then 'solved' by a sequence of moves that sort the facets by colour. As a generalisation, combination puzzles also include mathematically defined examples that have not been, or are impossible to, physically construct. Description A combination puzzle is solved by achieving a particular combination starting from a random (scrambled) combination. Often, the solution is required to be some recognisable pattern such as "all like colours together" or "all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hungarian Language
Hungarian () is an Uralic language spoken in Hungary and parts of several neighbouring countries. It is the official language of Hungary and one of the 24 official languages of the European Union. Outside Hungary, it is also spoken by Hungarian communities in southern Slovakia, western Ukraine ( Subcarpathia), central and western Romania (Transylvania), northern Serbia (Vojvodina), northern Croatia, northeastern Slovenia (Prekmurje), and eastern Austria. It is also spoken by Hungarian diaspora communities worldwide, especially in North America (particularly the United States and Canada) and Israel. With 17 million speakers, it is the Uralic family's largest member by number of speakers. Classification Hungarian is a member of the Uralic language family. Linguistic connections between Hungarian and other Uralic languages were noticed in the 1670s, and the family itself (then called Finno-Ugric) was established in 1717. Hungarian has traditionally been assigned to the Ugric alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picture Disc
Picture discs are gramophone (phonograph) records that show images on their playing surface, rather than being of plain black or colored vinyl. Collectors traditionally reserve the term picture disc for records with graphics that extend at least partly into the actual playable grooved area, distinguishing them from picture label discs, which have a specially illustrated and sometimes very large label, and picture back discs, which are illustrated on one unplayable side only. The beginnings A few seven-inch black shellac records issued by the Canadian Berliner Gramophone Company around 1900 had the "His Master's Voice" dog-and-gramophone trademark lightly etched into the surface of the playing area as an anti-piracy measure, technically qualifying them as picture discs by some definitions. Apart from those debatable claimants for the title of "first", the earliest picture records were not discs, strictly speaking, but rectangular picture postcards with small, round, transpar ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Axis Of Rotation
Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession. According to Euler's rotation theorem, simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time, a new axis of rotation will appear. This article assumes that the rotation is also stable, such that no torque is required to keep it going. The kinematics and dynamics of rotation around a fixed axis of a rigid body are mathematically much simpler than those for free rotation of a rigid body; they are entirely analogous to those of linear motion along a single fixed direction, which is not true for ''free rotation of a rigid body''. The expressions for the kinetic energy of the object, and for the forces on the parts of the object, are also simpler for rotation around a fixed axis, than for ...

Mechanical Puzzles
A mechanical puzzle is a puzzle presented as a set of mechanically interlinked pieces in which the solution is to manipulate the whole object or parts of it. While puzzles of this type have been in use by humanity as early as the 3rd century BC, one of the most well-known mechanical puzzles of modern day is the Rubik's Cube, invented by the Hungarian architect Ernő Rubik in 1974. The puzzles are typically designed for a single player, where the goal is for the player to see through the principle of the object, rather than accidentally coming up with the right solution through trial and error. With this in mind, they are often used as an intelligence test or in problem solving training. History The oldest known mechanical puzzle comes from Greece and appeared in the 3rd century BC. The game consists of a square divided into 14 parts, and the aim was to create different shapes from these pieces. This is not easy to do.

1980s Toys
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire *January 28 **Publius Septimius Geta, son of Septimius Severus, receives the title of Caesar. **Caracalla, son of Septimius Severus, is given the title of Augustus.
