Collapsible woven refugee shelters powered by the sun

Collapsible woven refugee shelters powered by the sun
More than 40 million people worldwide have been displaced from their homes and left to find shelter in strange lands. Maybe they find a tarp, or a tent, but their quality of life almost always remains dismal. To close this gap in need, Jordanian-Canadian architect and designer Abeer Seikaly designed a new kind of shelter. One that allows refugees to rebuild their lives with dignity. RELATED: Gorgeous shape-shifting shelters for nomads and refugees that move with the weather Seikaly, now living in Amman, Jordan is well poised to design a dwelling for refugees given that her ancestors in Jordan probably toggled between nomadic and sheltered life in the desert for centuries. “The movement of people across the earth led to the discovery of new territories as well as the creation of new communities among strangers forming towns, cities, and nations,” writes Seikaly in her design brief.

The Science of Beauty by Maria Popova “Attitudes toward beauty are entwined with our deepest conflicts surrounding flesh and spirit.” “That is the best part of beauty, which a picture cannot express,” Francis Bacon observed in his essay on the subject. And yet for as far back as humanity can peer into the past, we’ve attempted again and again to capture and define beauty. For Indian philosopher Tagore, beauty was the Truth of eternity. That’s precisely what Harvard’s Nancy Etcoff sets out to unearth in Survival of the Prettiest: The Science of Beauty (public library) — an inquiry into what we find beautiful and why that frames beauty as “the workings of a basic instinct” and explores such fascinating facets of the subject as our evolutionary wiring, the ubiquitous response to beauty across human cultures, and the universal qualities in people that evoke this response. Etcoff begins by confronting our intellectual apologism for the cult of beauty: In Brazil there are more Avon ladies than members of the army.

Just Intonation Toolkit The Just Intonation Toolkit is a resource that allows musicians to hear and play intervals other those found in equal temperament tuning system. Various existing systems of just intonation can be selected and then played either with the computer keyboard, a MIDI keyboard, or from an external application. The intervals can be played as zither sounds, organ sounds, piano sounds, or sine tones. You can also specify your own intervals and save the resulting intonation system as a preset. There are several tuning systems built in: La Monte Young's Well Tuned Piano (1973 tuning) Harry Partch's 43 tone system Harry Partch's proposed 4 string instrument for the comparison of equal temperament with various systems of just intonation Intervals from the 5-limit tonality diamond Greek Mixolydian Scales The tetrachord tunings of Archytas, Eratosthenes and Didymos Greek Mixolydian Scales Ling Lun's pentatonic and 12-note systems The systems implemented are based chiefly on the following texts:

untitled Back to Map Page February, 2000: Chernobyl (Ukraine) On the morning of April 26, 1986, a small town in the former Soviet Union was the site of a nuclear explosion that literally shook the earth. The historic accident at Chernobyl Nuclear Plant Reactor 4 in the Ukraine caused severe radioactive contamination. Families within a 30-km zone of the power plant were evacuated, and in the months that followed, extensive contamination was discovered in areas up to 100 km from the site. In 1989, three years after the explosion, the Soviet government asked the International Atomic Energy Agency (IAEA) to assess the radiological and health situation in the area surrounding the power plant. Apparently these toxic substances entered the food chain via grazers, such as cows and other livestock, that fed on plants grown in contaminated soils. Cannabis sativa. Overall, phytoremediation has great potential for cleaning up toxic metals, pesticides, solvents, gasoline, and explosives.

What is coppicing? | BBC Three - Secrets of the Superbrands (Technology) Pitch (music) In musical notation, the different vertical positions of notes indicate different pitches. Play top & Play bottom Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system.[5] In most cases, the pitch of complex sounds such as speech and musical notes corresponds very nearly to the repetition rate of periodic or nearly-periodic sounds, or to the reciprocal of the time interval between repeating similar events in the sound waveform.[8][9] Pitch depends to a lesser degree on the sound pressure level (loudness, volume) of the tone, especially at frequencies below 1,000 Hz and above 2,000 Hz. The relative perception of pitch can be fooled, resulting in aural illusions.

Outernet | WiFi for the World from Outer Space The San Francisco Globe When people dream of their ideal home, they probably expect to spend some serious money for it. This was not the case for Steve Areen. With just $9,000 USD and 6 weeks, he built his dream abode in Thailand. Steve started from scratch. With help from his friends, they quickly made progress using a combination of cement and clay bricks. $6,000 enabled them to build the base structure. An additional $3,000 was spent on details. Steve's work definitely reminds us that less is indeed more, and that spending more money doesn't always mean better results.

Shropshire Master Composters News: How to make a compost bin from old car tyres We were chatting the other day about how to keep a recycling theme to your gardening and home composting and we really like the idea of making compost bins yourself out of recycled materials. I've seen people compost in deceased fridge-freezers, old tea chests, sometimes using worn carpets or polyethelyne sheeting or making their own from old wooden pallets. But one of the simplest systems though is the old car tyre stack. Here's one we made earlier... I would add some caution though - old car tyres may be a great free source of ready to go, recycled material, but use them with caution because they are likely to have traces of oil and all sorts on the rubber. So, here’s how to go about it: First, find yourself five used car tyres - you can get them free off - alternatively most garages have to pay a fortune to get rid of them so will be delighted that you want them!

40 Of The Most Powerful Social Issue Ads That’ll Make You Stop And Think Many people complain about advertisements as an obnoxious way for companies to invade our everyday lives and cram their products down our throats, but that’s not all that advertisements are good for. The advertisements on this list are excellent examples of effective advertising strategies for social issue campaigns that let their voices be heard. Show Full Text A well-made advertisement is designed to grab your attention and to remain in your memory long after you’ve left it behind, and that is exactly what many of these social causes need. Getting people to think and worry about various social and environmental issues (or even simply getting them to be aware of them) is important for raising public supporting and affecting meaningful changes. A few of these ads are, in fact, commercial ads, but it’s still nice that they champion socially or environmentally aware causes/products. Just like with commercial advertisements, having just the facts is not enough. “THE END. Unhate Buckle up.

Chromatic scale Chromatic scale drawn as a circle: each note is equidistant from its neighbors, separated by a semitone of the same size. The most common conception of the chromatic scale before the 13th century was the Pythagorean chromatic scale. Due to a different tuning technique, the twelve semitones in this scale have two slightly different sizes. Thus, the scale is not perfectly symmetric. Many other tuning systems, developed in the ensuing centuries, share a similar asymmetry. Equally spaced pitches are provided only by equal temperament tuning systems, which are widely used in contemporary music. The term chromatic derives from the Greek word chroma, meaning color. Notation[edit] The chromatic scale may be notated in a variety of ways. Ascending and descending:[1] The chromatic scale has no set spelling agreed upon by all. Non-Western cultures[edit] Total chromatic[edit] See also[edit] Sources[edit] External links[edit] Recommended Reading[edit]

We've been splitting wood all wrong Splitting wood is one of the least favorite tasks of woodstove owners, and even for people who are just chopping for a decorative fireplace or pit, it gets unfun very rapidly. The repetitive motion and high amount of energy required are demanding, and the concussive force from blow after blow can really set a pair of shoulders aching. As if that wasn't bad enough, you have to wrench the axe out of the wood if it doesn't split on the first try...and there's always the risk of injury. The basic shape and design of the axe hasn't changed in, well, millennia, as attested to by archaeological discoveries from around the world. The result is the Vipukirves, a revolutionary axe that allows people to work smart, not hard. What differentiates it from regular axes, and how does it work? When the user strikes down, the weighted axe automatically turns to the right, levering the loosened piece of wood away from the rest of the log. Interested in seeing it in action?
