Kurt Wenner. This amazing street painting, called Dies Irae, was created by Kurt Wenner in a medieval town square in Italy.

Again, note that it is an anamorphic image - it only works from this viewpoint. If you walked around to the other side of the painting, it just would not work at all. Here, the human figure gives a sense of scale, as he peers into the abyss. In another street painting, called Reflections, the four human figures are an essential part of the image, as they look into their painted reflection... Kurt Wenner's work is shown here with the artists permission. Visit the Kurt Wenner web site. Another artist who uses anamorphic techniques is the Hungarian István Orosz. Allard Energy - Ethanol.

How to build shelves. This article also available in Russian and Spanish (help with translations) You can buy simple garage shelving kits at places like Home Depot or Ikea for about as much as it would cost to buy the lumber.

How to build shelves

But these shelves are typically not overly sturdy. This page describes how to build these cantilevered shelves of my design. Properly built, the shelves are strong enough one can climb up the front of them. The basic design uses two boards nailed to either side of a 2x4, with a smaller diagonal piece to brace the shelf. All the joints are glued to give it the necessary stiffness. If you have a table saw handy, the parts for one shelf support can be cut from one short piece of 2x4 as shown at left. People have on occasion asked me about what angle to cut the wood at. I cut the taper of the boards with simple jig consisting of a piece of lumber cut at an angle on my table saw sled. The next step was to nail one half of each bracket together. Here's testing the strength of the shelf. Rare Historical Photos Pt. 4 [18 Pics]

The Simple Dollar & Everything You Ever Really Needed to Know About Personal Finance on the Back of Five Business Cards. A few days ago, I had lunch with an individual who is considering hiring me to give a multi-hour seminar to a business convention on personal finance.

The Simple Dollar & Everything You Ever Really Needed to Know About Personal Finance on the Back of Five Business Cards

This person knows me from the local community and is a reader of The Simple Dollar and he felt that I might be the right person to give such a presentation. During the lunch, out of the blue, he asked me to give a five minute nutshell version of what I would present to the group. I thought for a minute, pulled a pen out of my pocket, and asked him for five business cards. In those next five minutes, I summarized everything I know about personal finance in a pocket-friendly presentation. I saved the business cards, scanned them in, and thus, for your enjoyment, is my presentation (with some extensive helper notes so you can know what I was actually saying while drawing these cards). 1.

Food. Material Science Madness: Crazy Metal Melts in Your Hand. There is an incredible metal that shatters like glass, melts in a human hand, attacks other metals but is non-toxic to humans, and acts like an alien life form when exposed to sulfuric acid and dichromate solution.

Material Science Madness: Crazy Metal Melts in Your Hand

It sounds too amazing to be true, but gallium is an absolutely real chemical element that’s found in some of the gadgets we use every day. But perhaps more interestingly, there are a ton of insane experiments scientists like to do with gallium. Thanks to its odd properties and behavior, gallium can do some pretty strange things in the lab. The above video shows what happens when gallium “attacks” aluminum. The “gallium beating heart” experiment is a popular one that shows how gallium can act like a living thing when submerged in sulfuric acid and a dichromate solution.

The melting gallium spoon is a fun demonstration that makes good use of gallium’s 85 degree (F) melting point. Aerogel: See-Through, Strong as Steel & Ligher than Air. Despite its incredibly low density, aerogel is one of the most powerful materials on the planet.

Aerogel: See-Through, Strong as Steel & Ligher than Air

It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air. Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. NASA continues to find new space-based applications for this incredible material. An aerogel window one inch thick has the effective insulative capacity of a ten-inch thick glass window system.

Aside from its other capabilities, aerogel also has amazing absorbing abilities.
