Contrail - About Contrail Contrail is a public art project that celebrates shared spaces, helps make bicycling safer and more fun. How to Use Contrail Contrail attaches to your bicycles and, as you ride, the device leaves a colorful trail behind you. Contrail uses washable, non-toxic chalking fluid made from eco-friendly pigments. CYCLEAN BIKE-POWERED WASHING MACHINE Turns out riding a bike can have more benefits than simply exercise or green-transportation… these days your pedal power can provide juice for your cell phone, the TV at your gym, and now even your washing machine. Pedal your way to cleaner clothes – and save energy and get fit in the process! We mentioned Cyclean in our earlier Green Your Appliances post as an eco-friendly option to most energy and water-sapping commercial washers.

Form CON (continuation sheet for applications) is also still available in paper. Paper forms are also available by postal mail upon request.
Chaos Click here to go to Physics Virtual Bookshelf Click here to go to the UPSCALE home page. James Gleick subtitled his popular book Chaos with Making a New Science. Note the word is "Science," not "Physics." The sub-title is quite reasonable. However, much of the work on chaotic systems occurs in Physics departments. scientific productivity - Software/App for electronic research notebooks - Academia Stack Exchange I use Org-mode to organize and track my research. It is an Emacs major mode that seems to hit most of your requirements. The .org files are plain text which should guard against bloat and lets you access them anywhere, even when you do not have Emacs or Org-mode available. linking to past experiments/pages Org-mode has linking capability to any type of file, as well as to specific locations in a document. latex equations
Students Build Bike-Powered Charging Station from Scratch © Christina Woodward/NAU As we become more and more dependent on our gadgets, we also are continually seeking out better ways to power them, from solar-powered chargers to human-powered ones. We've seen ideas for piezoelectric sneakers to movement-powered iPhones, but one idea that always seems to come back is pedal power. Why not use the energy you create pedaling a bike charge to our gadgets too? There have been quite a few incarnations of this idea, but it's always refreshing to see a fresh take on it, especially when it's a group of students who go full DIY and build a bike charging station completely from scratch, including the bike.

Dig Deeper into the Scandal Globally, extreme poverty has been halved in 20 years, and could be virtually wiped out by 2030. But much of the progress that has been made is at risk – not because of natural disasters or new diseases, but because of something far more insidious. Analysis by the ONE Campaign suggests that at least $1 trillion is being taken out of developing countries each year through a web of corrupt activity that involves shady deals for natural resources, the use of anonymous shell companies, money laundering and illegal tax evasion. This is not international aid – which is making a tangible difference. Massive sums are being taken out of developing countries’ own economies, preventing them from financing their own fight against extreme poverty, disease and hunger. It is nothing short of a trillion-dollar scandal.
How to Make Everything Ourselves: Open Modular Hardware A modular system unites the advantages of standardisation (as parts can be produced cheaply in large amounts) with the advantages of customisation (since a large diversity of unique objects can be made with relatively few parts). Modularity can be found to a greater or lesser extent in many products (like bicycles and computers) and systems (like trains and logistics), but the best examples of modular systems are toys: LEGO, Meccano, and Erector (which is now the brand name of Meccano in the US). LEGO, Meccano and Erector are composed of relatively few elementary building blocks, which can be used to build various objects. The parts can then be disassembled and re-used to build something completely different. Copyright law of the United States The Copyright Law of the United States intends to encourage the creation of art and culture by rewarding authors and artists with a set of exclusive rights. Federal Copyright law grants authors and artists the exclusive right to make and sell copies of their works, the right to create derivative works, and the right to perform or display their works publicly. These exclusive rights are subject to a time limit, and generally expire 70 years after the author's death.
Undocumented Matlab I would like to welcome Chris Parmer of plot.ly, who will describe the integration of Plotly graphs and charts in Matlab. Unlike the open-source JFreeChart and Waterloo plotting libraries that were described here in the past, Plotly is a commercial (not open-source) service. Contact Plotly for the exact license terms and costs. However, as you can see below, there’s a demo account that you can freely use. While I do not directly endorse Plotly as a commercial operation, I love its beautiful visualizations and interactivity.
Designs for Working Why your bosses want to turn your new office into Greenwich Village. In the early nineteen-sixties, Jane Jacobs lived on Hudson Street, in Greenwich Village, near the intersection of Eighth Avenue and Bleecker Street. It was then, as now, a charming district of nineteenth-century tenements and town houses, bars and shops, laid out over an irregular grid, and Jacobs loved the neighborhood. In her 1961 masterpiece, “The Death and Life of Great American Cities,” she rhapsodized about the White Horse Tavern down the block, home to Irish longshoremen and writers and intellectuals–a place where, on a winter’s night, as “the doors open, a solid wave of conversation and animation surges out and hits you.” Her Hudson Street had Mr.
