Proffessor Rubix Cube
The Professor's Cube is a mechanical puzzle, a 5×5×5 version of the rubix's Cube. It has qualities in ordinary with both the example 3×3×3 rubix's Cube and the 4×4×4 rubix's Revenge, and knowing the solution to either can help when employed on the 5×5×5 cube.
The example Professor's Cube design by Udo Krell works by using an expanded 3×3×3 block as a cover with the edifice edge pieces and corners sticking discover from the spherical edifice of identical execution to the 3×3×3 cube. The non central edifice pieces are fitted into spaces on the surface of the 3×3×3 mantle, and the non central edges slotted between them. All non-central pieces have extensions that sound into allotted spaces on the outer pieces of the 3×3×3, which keeps them from falling discover of the block while making a turn. The immobile centers have digit sections (one visible, digit hidden) which can invoke independently. This feature is unique to the example design.
The Eastsheen version of the teaser uses a assorted mechanism. The immobile centers stop the edifice cubelets incoming to the central edges in place, which in invoke stop the edge cubelets. The non-central edges stop the corners in place, and the internal sections of the corner pieces do not reach the edifice of the cube.
The V-Cube 5 mechanism, designed by Panagiotis Verdes, has elements in ordinary with both. The corners reach to the edifice of the teaser (like the example mechanism) and the edifice pieces stop the central edges in place (like the Eastsheen mechanism). The middle edges and edifice pieces conterminous to them make up the supporting inclose and these have extensions which stop rest of the pieces together. This allows smooth and fast rotation and creating arguably the fastest and most durable version of the puzzle. Unlike the example 5×5×5 design, the V-Cube 5 execution was designed with speedcubing in mind.
The current record for finding the Professor's Cube in an official competition is 1 time 7.25 seconds, set by Dan Cohen at the Big Cubes Summer 2009
Dan Cohen holds the current world record for an average of five solves, with the average of 1:16.75, set at the UPenn Spring Open on March 21 2009.
