The work of M.C. Escher needs no introduction. We have all learned to appreciate the impossibilities that this master of illusion's artwork presents to the layman's eye. Nevertheless, it may come as a surprise for some, but many of the so-called 'impossible' drawings of M. C. You are also invited to watch our movie: "Escher for Real" and "Impossibly Real". "Escher for Real" "Impossibly Real" Convention In the following sequences, figures are frequently presented in pairs. The Penrose Triangle We start with the Penrose triangle object (also independently invented by Oscar Reutersvard). The Penrose Rectangle The impossible shape conveyed by the Penrose triangle is the most well-known one. The Penrose Pentagon Similarly and following the construction of a Penrose triangle and Penrose rectangle, one can easily create an arbitrary Penrose n-gon. The Penrose Triangle II Here we present another way to simulate and realize geometry that looks like the Penrose triangle from a certain view. All M.C.

Color Psychologyby David Johnson Like death and taxes, there is no escaping color. It is ubiquitous. Yet what does it all mean? Colors often have different meanings in various cultures. Black Black is the color of authority and power. White Brides wear white to symbolize innocence and purity. Red The most emotionally intense color, red stimulates a faster heartbeat and breathing. The most romantic color, pink, is more tranquilizing. Blue The color of the sky and the ocean, blue is one of the most popular colors. Green Currently the most popular decorating color, green symbolizes nature. Yellow Cheerful sunny yellow is an attention getter. Purple The color of royalty, purple connotes luxury, wealth, and sophistication. Brown Solid, reliable brown is the color of earth and is abundant in nature. Colors of the Flag In the U.S. flag, white stands for purity and innocence. Food for Thought While blue is one of the most popular colors it is one of the least appetizing.

Scienceing! • visualizingmath: Impossible Figures - Art by...Miegakure: A puzzle-platforming game in four dimensionsMiegakure is a platform game where you navigate a four-dimensional world to perform miraculous feats and solve puzzles. Miegakure is a puzzle-platforming game that lets you explore and interact with a four-dimensional world. The fourth dimension in this game works just like the first three: it is a mathematical generalization. Your ability to move in the fourth dimensions in addition to the usual three allows you to perform miraculous feats like seeing inside closed buildings, walking through walls, stealing objects from closed containers, binding two separate rings without breaking them, etc... These actual consequences of the mathematical formulation of 4D space have been thought about for more than a century (in the 1884 novella Flatland for example) but it is the first time anyone can actually perform them, thanks to the video game medium. Our world is three-dimensional: width, depth, and height. In this case the fourth dimension is not time. Is there a demo? Miegakure TRAILER

Soda Machine HackMost modern vending machines have little computers inside. A tiny screen usually displays some information. Although relatively little known, pressing a certain combinations of buttons can control the settings. For instance, you can check the internal temperature, view the amount of money inside, empty change, or dump certain beverages. It will generally only work on new machines which is pictured on the right side. Press the buttons     one after another. Once inside the buttons become controls for navigating the menu system. Button  – Back/ExitButton  – DownButton  – UpButton  – Select You should now be able to scroll through the available settings. Here are the descriptions of some of the settings you may run into: Pressing the coin return or back button also exits out of the setting menus. Although access to those settings is usually enabled, it is sometimes locked down by the owner or maintenance. CPO – Coin payment mode dumps coins out of the machine.
