How to Solve a Rubik's Cube (Easy Move Notation)
First LayerMiddle LayerLast layerNotations Edited by NatK, Krystle, Mimi, BohemianWikipedian and 59 others The Rubik's Cube can be very frustrating and may seem next to impossible to restore to its original configuration. However, once you know a few algorithms, it is very easy to solve. Ad Steps Method 1 of 4: First Layer 1Familiarize yourself with the Notations at the bottom of the page.Ad 2Choose one face to start with. Method 2 of 4: Middle Layer 1Place the four edges of the middle layer. Method 3 of 4: Last layer 1Permute the corners. Method 4 of 4: Notations 1This is the key to the notations used.The pieces that compose the Rubik's Cube are called Cubies, and the color stickers on the Cubies are called facelets.There are three types of Cubies: The centers (or center pieces), at the center of each face of the Cube.

Holography
Two photographs of a single hologram taken from different viewpoints The holographic recording itself is not an image; it consists of an apparently random structure of either varying intensity, density or profile. Overview and history[edit] The Hungarian-British physicist Dennis Gabor (in Hungarian: Gábor Dénes),[1][2] was awarded the Nobel Prize in Physics in 1971 "for his invention and development of the holographic method".[3] His work, done in the late 1940s, built on pioneering work in the field of X-ray microscopy by other scientists including Mieczysław Wolfke in 1920 and WL Bragg in 1939.[4] The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston (BTH) Company in Rugby, England, and the company filed a patent in December 1947 (patent GB685286). Several types of holograms can be made. Holograms can also be used to store, retrieve, and process information optically.[18] How holography works[edit] Recording a hologram
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.

HOW TO CHEAT AT EVERYTHING
Over lunch with Simon Lovell, a fascinating former card shark, Allison Schrager learns all sorts of things about how swindlers operate ... Special to MORE INTELLIGENT LIFE "I can spot someone's weakness a mile away. In any room I can pick out the best target," says Simon Lovell, reformed con artist and famed magician, when asked over lunch about the root of his talents. "Take that woman over there." "Or that man over there, over-dressed, too neat, over-confident, thinks he is too smart to be taken." "But ultimately, anyone can be conned, if you have the balls to do it." Simon Lovell should know. Presently, instead of subjecting people to cons, Mr Lovell stars in a one-man off-Broadway show, "Strange and Unusual Hobbies". "I could sell shit at an anti-scat party," he says, "you have to figure out someone's wants and needs and convince them what you have will fill their emotional void." It requires avid study of psychology and body language. Con men tend to be excellent conversationalists.
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. You may also enjoy:

Twitter: How to archive event hashtags and create an interactive visualization of the conversation Jisc CETIS MASHe
The use of Twitter to collecting tweets around an event hashtag allowing participants to share and contribute continues to grow and has even become part of mass media events, various TV shows now having and publicising their own tag. This resource is often lost in time, only tiny snippets being captured in blog posts or summaries using tools like Storify, which often loose the richness of individual conversations between participants. It doesn’t have to be this way. Using a combination of Google Spreadsheets as a data source and a simple web interface to add interactivity it’s possible to let users explorer your entire event hashtag and replay any of conversations. View example conversation replay Try out a LIVE version Update: If you are still struggling to understand the concept Radical Punch have done a overview of this tool Here's how to archive event hashtags and create an interactive visualization of the conversation (written instructions below): Capturing the tweets
