Ground Breaking Material Technology Imagine being able to use concrete on slopes, in water, and in other hard to reach places - with no molds, no mixing, and minimal equipment. Concrete Cloth is flexible and will bend and curve, enabling it to follow the natural contours of the land, including ditches and slopes. Unlike regular concrete, Concrete Cloth can be installed in the rain, and other wet conditions, virtually eliminating rescheduling due to weather conditions. It comes in a variety of sizes, including man-portable rolls that two men can carry, reducing the need for heavy machinery. The fabric structure also reinforces the concrete and reduces cracking, while using up to 95% less concrete than conventional methods. Concrete Cloth has a low alkaline reserve and a low wash rate for a low ecological impact.

Photography 101.org - How to Choose a Lens Your lens is quite possibly the most important part of your camera. SLR and dSLR (digital SLR) cameras (and even some non SLR/dSLR) allow you to change out the lenses, to suit all of your photography needs. A good lens will produce sharp crystal-clear pictures with beautiful detail. A low quality lens can hinder you to the point where you'd be better off shooting with a disposable camera. Basically, your lens makes or breaks your camera. Different lenses have different purposes, functions, and features.
NASA Simulates Asteroid Mission for Potential 2025 Flight HOUSTON — NASA’s plans to send astronauts to an asteroid by 2025 moved 10 days closer to being a reality this week, even though the target of that mission has yet to be found in space. The agency’s Research and Technology Studies’ (RATS) 10-day simulated asteroid mission, which ended Wednesday (Aug. 29), involved scientists and flight controllers at NASA’s Johnson Space Center in Houston evaluating new operations and exploration techniques for how astronauts might work above and on the surface of one of the small, rocky, solar system bodies. The test used a variety of simulation technologies, including virtual reality and a custom rig that helped recreate the microgravity environment found at an asteroid.

F-Stop and Aperture, Still Photography Camera Guide stsite.com We often see on a camera brochure that says "Lens: 35-105mm f-3.5-f8". The "f-3.5-f8" is called the F-stop or the maximum aperture of the lens. This figure is derived from dividing the focal length of the lens by the aperture opening of the lens. The aperture is the opening formed by a system of metal leaves in the lens that open up and close down to control the volume of light passing through the lens.
Dark Matter Exposed? Gamma-Ray Find Excites Scientists Energetic light seen radiating from the center of the Milky Way may be the best evidence yet of dark matter, the invisible stuff thought to be hiding throughout the universe. A new study has found a strong signal of gamma-rays — light of a very short wavelength — coming from the middle of our galaxy, which may be the result of exploding dark matter. Scientists think dark matter, which seemingly makes up the majority of matter in the universe, is made of particles called WIMPs ("weakly interacting massive particles"). And WIMPs, when they get very close to other WIMPs, should annihilate each other, because these particles are thought to be their own antiparticles. (When particles of matter and their antimatter counterparts meet, they destroy each other.)

However, what we should have done in the inspirational posts is not just provide you with some inspiration for your work, but also present useful photographic techniques which can help you to achieve optimal pictures for your designs.
Aerographite Is the World's Lightest Material, Is a Total Airhead and Kind of Weird The last time we looked at ultra-lightweight materials, we were thoroughly impressed by a spongy, metallic micro-lattice that held a density of 0.9 milligrams per cubic centimeter (mg/cc). Now, a team of German scientists from the Technical University of Hamburg and University of Kiel has developed a new carbon-nanotube-based material called Aerographite that’s four times lighter at 0.2mg/cc. As you might have surmised from Aerographite’s name, it’s a material made of mostly air--99.99 percent, to be exact--along with carbon nanotubes. The scientists created the material by growing an interlinking chain of carbon nanotubes onto a zinc oxide template. Despite Aerographite’s lightweight nature, it’s actually quite tough.
5 Posh Private Islands for Sale Despite the trying economic times, 2011 was a standout year for extravagant private island estates—some of them thrust to market thanks to the bankruptcy of their owners. Topping our list of favorites is the outrageously expensive Italian archipelago known as the Li Galli Islands. Lying just off the Amalfi Coast of Italy, the $268 million property was built by choreographer Leonide Massine in 1924, passed to fellow Russian dancer Rudolf Nureyev, later modified by the great Le Corbusier, and hosted stars like Greta Garbo, Ingrid Bergman, Sofia Loren, and Jacqueline Kennedy Onassis.
