INTEGRAF--How to Make Holograms "Everything should be made as simple as possible, but not simpler” - Albert Einstein We attempt to follow this dictum so you can make holograms easily. The procedures we propose herein are as simple as it is physically possible. In the process, we make holography not only as simple as possible, but safer, less expensive, and more accessible to young people. Most of the essential items described in this article can be found in Integraf's holography kits or are available separately. The kits provide materials for you to make many kinds of holograms, including reflection holograms and transmission holograms. The figure below shows a Class IIIa diode laser with an output of 3 to 4 mW when operated by 3.0 v dc. An excellent support for such a small laser is a wooden clothespin, as shown below. The wooden clothespin offers another advantage. The “white light reflection hologram” is the simplest to make. 4.1 Supplies 4.2 Preparing the object It is not necessary to have a completely dark room.

Patrick Pittman | Writer, broadcaster, developer, other stuff. How to Make a Hologram Edit Article Edited by Alecander, Ben Rubenstein, Nicole Willson, Krystle and 44 others It's easier to make a 3D hologram than you think. In fact, each year thousands of hobbyists, students, and teachers make holograms at home and school. Ad Steps 1Gather your holography supplies and household materials listed in the "Things You'll Need" section below. 14View your hologram after it is completely dried with a point source such as that from a projector, flashlight, spotlight, LED white light, or the sun. Tips Realize that vibrations and microscopic movement of even 1 millionth of a meter can ruin a hologram. Warnings Carefully read and follow all instructions for using your laser. Things You'll Need Holography SuppliesNote: Budget is around $100PFG-03M professional holographic film platesRed holography laser. Article Info
John Conway's Game of Life The Game The Game of Life is not your typical computer game. It is a 'cellular automaton', and was invented by Cambridge mathematician John Conway. This game became widely known when it was mentioned in an article published by Scientific American in 1970. It consists of a collection of cells which, based on a few mathematical rules, can live, die or multiply. playgameoflife.com New developments of this page will continue on playgameoflife.com. playgameoflife.com The Simulation Figure from the XKCD RIP John Conway comic. The Rules For a space that is 'populated': Each cell with one or no neighbors dies, as if by solitude. Each cell with four or more neighbors dies, as if by overpopulation. Each cell with two or three neighbors survives. For a space that is 'empty' or 'unpopulated' Each cell with three neighbors becomes populated. The Controls Choose a figure from the pull-down menu or make one yourself by clicking on the cells with a mouse. Development Edwin Martin <edwin@bitstorm.org>
Desktop Helium Neon Laser Lamp Build Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY laser projects. I’d like to show off my new desk top laser lamp! It’s a fairly simple project and makes for a nice display piece. Basically, this is a 10 inch tube with a gorgeous laser inside. I bought some basic materials and a project box from Radio Shack. I added some solid rods in the front just to add stability to the mount.

The expression is named after American cartoonist and inventor Rube Goldberg (1883–1970). Over the years, the expression has expanded to mean any confusing or complicated system. For example, news headlines include "Is Rep. Bill Thomas the Rube Goldberg of Legislative Reform?"[1] and "Retirement 'insurance' as a Rube Goldberg machine".[2] Origin[edit] Professor Butts and the Self-Operating Napkin In 1931, the Merriam–Webster dictionary adopted the word "Rube Goldberg" as an adjective defined as accomplishing something simple through complicated means.[4] Similar expressions worldwide[edit] Professional artists[edit] Peter Fischli & David Weiss, Swiss artists known for their art installation movie Der Lauf der Dinge (The Way Things Go, 1987).

احصاء Feature creep Feature creep, creeping featurism or featuritis is the ongoing expansion or addition of new features in a product, such as in computer software.[1] Extra features go beyond the basic function of the product and so can result in over-complication rather than simple design. Causes[edit] The most common cause of feature creep is the desire to provide the consumer with a more useful or desirable product, in order to increase sales or distribution. However, once the product reaches the point at which it does everything that it is designed to do, the manufacturer is left with the choice of adding unneeded functions, sometimes at the cost of efficiency, or sticking with the old version, at the cost of a perceived lack of improvement. Another major cause of feature creep might be a compromise from a committee which decides to implement multiple, different viewpoints in the same product. Marketing considerations: Product life cycle and the competition impetus[edit] Introduction[edit] Growth[edit]
3D printing An ORDbot Quantum 3D printer. 3D printing or additive manufacturing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.

Kolmogorov complexity In algorithmic information theory (a subfield of computer science and mathematics), the Kolmogorov complexity (also known as descriptive complexity, Kolmogorov–Chaitin complexity, algorithmic entropy, or program-size complexity) of an object, such as a piece of text, is a measure of the computability resources needed to specify the object. It is named after Andrey Kolmogorov, who first published on the subject in 1963.[1][2] abababababababababababababababab 4c1j5b2p0cv4w1x8rx2y39umgw5q85s7 The first string has a short English-language description, namely "ab 16 times", which consists of 11 characters. More formally, the complexity of a string is the length of the shortest possible description of the string in some fixed universal description language (the sensitivity of complexity relative to the choice of description language is discussed below). Definition[edit] Any string s has at least one description, namely the program: function GenerateFixedString() return s K(s) = |d(s)|. ∀s. ∀s.
