Leslie's Artgallery : Digital Art - Voronoi Fractal Voronoi Fractal Frederik Vanhoutte (2008) In mathematics, a Voronoi diagram, named after Georgy Voronoi, also called a Voronoi tessellation, a Voronoi decomposition, or a Dirichlet tessellation (after Lejeune Dirichlet), is a special kind of decomposition of a metric space determined by distances to a specified discrete set of objects in the space, e.g., by a discrete set of points (source Wikipedia). More details about Voronoi diagrams have been published by Shubhendu Trivedi on his blog Onionesque Reality. Voronoi fractals are created by dressing a Voronoi diagram from some points. Next, more points are added and new Voronoi diagrams are created inside each original Voronoi region. Leslie's Artgallery : Digital Art - Voronoi Fractal

index Over the years several mechanical drives have been proposed for various reasons, most importantly to reduce sidewise forces onto pistons or sliding parts with the objective to reduce friction and wear and satisfying constraints imposed by the thermodynamics of Stirling engines. Literally, hundreds of different kinematic mechanisms have been invented over the past centruries, a nice collection of these can be found at Cornell University's Model collection. Follow the link to "Models" and click on any of the 3 collections offered to get a nice menu for all documented models. Look for Straight-line Mechanism ( in particular model S35, Peaucellier ) if you are interested in the conversion from straight-line to rotary motion and back. To first order, two properties of a drive mechanism influence the performance of Stirling engines, the volume amplitude ratio and the phase lag between expansion and compression space. index
Optical Illusions and Visual Phenomena Optical Illusions and Visual Phenomena Op­ti­cal il­lu­sion are fas­ci­nat­ing while teach­ing us about our vi­sual per­cep­tion, and lim­its thereof. My em­pha­sis here is on the beauty of per­cep­tual phe­nom­ena, on in­ter­ac­tive ex­per­i­ments, and ex­pla­na­tion of the vi­sual mech­a­nisms in­volved – to the de­gree that they are un­der­stood Be­friend­ing mo­bile de­vices: >50 in­ter­ac­tive demos now with­out Flash, but re­quire up-to-date browser ver­sions. Don’t let it irk you if you don’t see all the phe­nom­ena de­scribed. For many il­lu­sions, there is a per­cent­age of peo­ple with per­fectly nor­mal vi­sion who just don’t see it, often for rea­sons cur­rently un­known. If you are not a vi­sion sci­en­tist, you might find my ex­pla­na­tion at­tempts too high­brow.

What is the Cube? The cube is a mathematical body formed by six equal squares. Other names are cubus or hexahedron. In the 1980's Rubik's cube was so popular that it was simply called "the cube". Cube Cube

Historical Physics Teaching Apparatus Instruments for Natural Philosophy Thomas B. Greenslade, Jr.Professor Emeritus of PhysicsKenyon College, Gambier, Ohio 43022GREENSLADE@KENYON.EDU In February 1975, Deborah Jean Warner, a Curator of Physical Science at the National Museum of American History, called me to ask if Kenyon had any historical physics teaching apparatus. I looked around my office, and reeled off the names of four or five good pieces of apparatus that I was using in my lectures. Historical Physics Teaching Apparatus
