Sound waves snuff fire

WTF ?

In 2004 Dmitriy Plaks and several of his fellow students at the
University of West Georgia tested whether sound waves can douse fires
in hopes of using sound to extinguish flames in a spacecraft. They
placed a candle in a large topless chamber with three bass speakers
attached to the walls. The candle was lit and the Canadian rock band
Nickelback's "How you remind me" was pumped through the subwoofers.
Within roughly 10 seconds, once the song hit a low note, the flame was
out, according to results published in 2005 in The Journal of the
Acoustical Society of America.

Sound waves snuff fire - Boing Boing


But the BIG question is, what if they played the Rolling Stones "Devil's Banquet" ?

Work It Out: More Activity = Slower Aging: Scientific American

New study links exercise to greater longevity

By Lisa Stein

AGING FAST: A new study shows that lack of exercise may speed the aging process.

Warning, couch potatoes: resting on your laurels may be hazardous to your health, not to mention make you old before your time.

"A sedentary lifestyle increases the propensity to aging-related disease and premature death," researchers at King's College London report today in the journal Archives of Internal Medicine. "Inactivity may diminish life expectancy not only by predisposing to aging-related diseases but also because it may influence the aging process itself."

Researcher Lynn Cherkas and colleagues reached their conclusions by examining the genetic material extracted from blood samples of some 2,400 twins. They specifically studied the length of telomeres (repeated DNA sequences) on the ends of chromosomes in leukocytes (white blood cells); the protective caps are believed to be markers of biological aging, because they shrink over time.

Their findings: the telomeres of subjects who exercised the most (an average of 199 minutes weekly) were longer than those of volunteers who worked out the least (a mere 16 minutes or less a week). The discrepancy was enough, researchers wrote, to suggest that the exercise mavens were on average as much as a decade biologically younger than the slackers.

"Such a relationship between leukocyte telomere length and physical activity level remained significant after adjustment for body mass index, smoking, socioeconomic status and physical activity at work," the authors report. "The mean difference in leukocyte telomere length between the most active and least active subjects was 200 nucleotides (chemical structural units of DNA and RNA), which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average."

The scientists speculate that stress, inflammation and oxidative stress (cell damage caused by oxygen exposure) may be responsible for shortened telomeres in physically inactive people. Exercise is among the factors found to help alleviate stress. Previous research has linked regular workouts to lower rates of cardiovascular disease, type 2 diabetes, cancer, high blood pressure, obesity and osteoporosis.

The researchers note that their findings support U.S. guidelines calling for individuals to exercise moderately for 30 minutes at least five days a week. "Our results. . . show that adults who partake in regular physical activity are biologically younger than sedentary individuals," they say. "This conclusion provides a powerful message that could be used by clinicians to promote the potential anti-aging effect of regular exercise."

Society and Solitude

"Made by hand, the craft object bears the fingerprints, real or metaphorical, of the person who fashioned it. These fingerprints are not the equivalent of the artist’s signature, for they are not a name."
- Octavio Paz (b. 1914)

Octavio Paz’s route was his own, not mine, but behind that route a path is traceable, and in that path I recognize an invaluable lesson: society and solitude — how to make these two compatible? His answer was to live life in full, alone and with others. To make oneself present by tracing one’s past and betting on the future.

So people die

The most famous feature on the Devils Thumb is its unclimbed Northwest Face, which rises 6,700 feet from the Witches Cauldron at its base to the summit, at an average angle of 67 degrees. This is unparalleled steepness for a face this size in North America. Unfortunately, the conditions prevalent on this face make it into perhaps the most dangerous climbing proposition on the continent as well.

Climbing history

The first ascent of the Devils Thumb was a landmark in North American mountaineering. Fred Beckey, along with Clifford Schmidtke, and Bob Craig, climbed the East Ridge, a route that combined technical difficulty equal to anything ever climbed on the continent to that time with great remoteness and terrible weather conditions.

The infamous Northwest Face has seen only failed attempts starting in 1977 (possibly earlier), through the present; at least three teams have died on the face.

Early August, 1977: Peter Cole,Nichols Rouner, and Rainsford Rouner. Finding the wall virtually devoid of snow or ice and with no obvious lines up the apparently rotten rock, the trio opted for a line heading to the west buttress, along the couloir that forms the right-hand margin of the face. Starting on an adjacent buttress below the Witches’ Tits, they continued across a hanging glacier.While the three were soloing, tragedy struck: Nichols died from rockfall.

He was almost 6'6", strong as lightening with a kind and quiet face, remarkably patient with her teenage moodiness. He flew in from Seattle that August of 1975 still smelling of mountains, crusty rocks, mossy green craggy holds. But mostly he came with a dare to dream, the dare to dream that you can only get from having parents who love you so much that they want your dreams to live .They hold you safely and let you go , they smile at your cleverness and delight in your charmed movements. They even encourage you to climb. And climb he did. Often and well. Beyond well, spectacularly well . But more significant than that, he discovered that climbing brought him close to God , wholeness , life and death. He pursues it like fire, relentlessly, without doubt, with his whole physique, with his soul.

Climbing is his world within and the world without , without loss. He cannot possibly lose while racing the sunset, holing up against searing winds and sleet , sleeping tied to the icy bare rock with only ice ax as companion. This is a sharp, dangerous world, but that this is the ONLY real world that he wants to exist in. Now and forever.

There's was a quick summer romance between teenagers. She was the long distance blond girl with the Texas drawl who liked to sing and play guitar.He was the Boston bred poet athlete. They were just about happiness , discovery and flying across the country on a whim. She was moody and often sad, he was in love with grace of thought and heart. Over the distance and months they lost touch. The melancholy summer romance girl continues to study and dream her life in Texas . Sometimes wishing to be a poet, a healer, a songwriter, a teacher .Seasons and years go by .She sees struggles, disappointment, moderate success and sometimes achieves true self expression. She doesn't think often of the August nights thirty one years ago when she was 18 and he was 17. She remembers more the vibrant aliveness during those hikes in Colorado sleeping in thunderstorms, hiding in drenched tents, hiking in open meadows with the blossoming columbine, being certain that life held good things. Missing that cedar scent of promise mostly. One day many many years later, she thinks of looking him up. She does a search and discovers that he died in 1977 perhaps just a year or two after their summer, on a mountain in Alaska. Her heart is broken for him and even more for his family. No one had bothered to tell her. She understands this. So thirty one years after, she writes for him.

True to yourself
you fell
backwards
in white hot sunshine
face upwards toward the reddened sky

Never once regretting
the fall
not from life
but toward light

your mother , the poet,
cried out in her sleep
what have you done?

without reservation
you answer

I have lived
I have lived

beautifly written , on positive emotions



PEPLab - Introduction
You have -- within you -- the fuel to thrive and to flourish,
and to leave this world in better shape than you found it.
Sometimes you tap into this fuel – other times you don’t.
But the sad fact is that most people have no idea
how to tap into this fuel or even recognize it when they do.
Where is this fuel within you?

You tap into it whenever you feel energized and excited by new ideas.
You tap into it whenever you feel at one with your surroundings, at peace.
You tap into it whenever you feel playful, creative, or silly.
You tap into it whenever you feel your soul stirred by the sheer beauty of existence.
You tap into it whenever you feel connected to others and loved.
In short, you tap into it whenever positive emotions resonate within you.

Bottled water is VERY bad for the environment



FilterForGood: Home

Duh! I've been trying to find a good water filter that doesn't take a nucleur physicist to install.
