John P. Milton is a meditation and Qigong instructor, author, and a pioneering environmentalist. He is the founder of Sacred Passage and the Way of Nature. About the book: https://www.amazon.com/gp/product/0385046561/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0385046561&linkCode=as2&tag=tra0c7-20&linkId=268051c278e62f5d26a866d80556fb86

He pioneered vision questing in contemporary Western culture in the 1940s. In 1945, at the time he began his sacred solo retreats in the wilderness, vision quests were unknown in the Americas outside Native American culture. He received his M.S. in ecology and conservation from the University of Michigan in 1963.[1] Milton is also known for organizing and leading dozens of expeditions into some of the wildest areas left on Earth, starting in his late teens. A founding father of the environmental movement in the early 1960s, he was a professor of environmental studies and a Woodrow Wilson Center scholar at the Smithsonian Institution. He was one of the first ecologists on staff at the White House as a member of the President's Council of Economic Advisors, and was a founding member of the environmental organization Friends of the Earth.

He is a frequent lecturer and workshop leader, and a pioneering, renowned, and sought-after meditation and Qi Gong teacher. Thousands of people have sought his instruction since he began teaching in the 1950s. He has developed unique practices for uniting inner and outer nature through training in Buddhist, Taoist, Vedantic, Tantric, and Native American spiritual traditions, and he incorporates T'ai chi and yoga in his work. The book Discovering Beautiful: On The Road To Somewhere includes several sections detailing a student's apprenticeship with John.

John's work in the world is also featured on the Transition United States web site.

His books and articles focus on inner development, Qi Gong and ecology. He recently published the book Sky Above, Earth Below. Devotees of Milton say his programs inspire Earth stewardship by cultivating natural wisdom and an open, loving heart in the wild.

John Milton lives in Tucson, Arizona.

Vandmærke: en feature dokumentarfilm

Uden vand er vi ingenting, tænkte den rejsende. Selv en kejser, der bliver nægtet vand, ville hurtigt blive til støv. Vand er den ægte monark, og vi er alle dets slaver.Salman RushdieHver en levende ting kræver vand. Vi mennesker interagerer med det på mange måder, mange gange om dagen. Men hvor ofte betragter vi kompleksiteten af denne interaktion? Og medmindre vi konfronteres med manglen på det, hvornår overvejer vi dets allestedsnærværelse i skabelsen, opretholdelsen og berigelsen af livet?Vandmærke er en feature dokumentarfilm, der samler forskellige historier fra hele verden om vores forhold til vand: hvordan vi tiltrækkes af det, hvad vi lærer af det, hvordan vi bruger det og konsekvenserne af forbruget. Vi ser enorme flydende søøre opdrætsfarme ud for Kinas Fujian kyst og byggepladsen for den største bue dæmning i verden - Xiluodu, seks gange større end Hoover- dæmningen. Vi besøger det barske ørken-delta hvor den magtfulde Colorado-flod ikke længere når havet og de vandforbrugende lædergarverier i Dhaka.Vi er vidne til, hvordan mennesker bliver tiltrukket af vand, lige fra US Open i surfing på Huntington Beach til Kumbh Mela i Allahabad, hvor tredive millioner mennesker samles til et helligt bad i Ganges-floden på samme tid. Vi taler med forskere, der borer i iskerner to kilometer dybt inde i det grønlandske indlandsis, og vandrer rundt om de sublime uberørte vandområder i det nordlige British Columbia.Filmet i fantastisk 5K ultra high-definition video og fuld af skyhøje luft perspektiver, viser denne film vand som et terraforming element og omfanget af dets rækkevidde, samt størrelsen af vores behov og brug. Dette er afbalanceret af særlige strejftog: et spøgende minde om en stjålet flod, en mystisk figur der strejfer rundt på gamle risterrasser, de afgørende data gemt i et million år gammelt stykke is, en pilgrims private ritual blandt tusindvis af andre ved vandkanten .Vandmærke er instrueret af den flere gange prisbelønnede filmskaber Jennifer Baichwal og den berømte fotograf Edward Burtynsky, og er den tredje del af Burtynskys ”Water” projekt, som omfatter bogen Burtynsky: Water og en stor fotografisk udstilling. Filmet og produceret af Nicholas de Pencier og tre år undervejs, er det en logisk forlængelse af trioens tidligere samarbejde, ”Manufactured Landscapes”. I Vandmærke er seeren fordybet i en verden defineret af en storslået naturkraft, som vi alt for ofte tager for givet - indtil den er væk.

Method of the Year 2011: Gene-editing nucleases - by Nature Video
00:03:37
skoleflix
9 Visninger · 2 år siden

Gene-editing nucleases can make targeted and precise changes to an organism's genome. This has opened up new possibilities for the study of gene function, as well as the treatment of disease. While gene-editing nucleases have been in use since the mid-1990s, in the form of zinc finger nucleases, the more recent discovery of TALENs (transcriptor-like effector nucleases) has created new interest. In this video, Nature Methods technology editor Monya Baker explains how gene-editing nucleases work and why they were chosen as Nature Methods 'Method of the Year' for 2011.

We live in a world of unseeable beauty, so subtle and delicate that it is imperceptible to the human eye. To bring this invisible world to light, filmmaker Louie Schwartzberg bends the boundaries of time and space with high-speed cameras, time lapses and microscopes. At TED2014, he shares highlights from his latest project, a 3D film titled "Mysteries of the Unseen World," which slows down, speeds up, and magnifies the astonishing wonders of nature.

Primitive Technology: Forge Blower
00:04:32
skoleflix
3 Visninger · 2 år siden

I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project.
Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted.
So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing.
Now when the fan spun, air entered the hole in the top of the housing and exited the spout in the side. Importantly, it doesn’t matter which way the fan spins, air always goes into the inlet and out the spout. Air is thrown out towards the walls of the housing and can only leave through the spout while the vacuum in the centre sucks new air into the housing through the inlet. A separate clay pipe called a tuyere was made to fit over the spout to direct air into the coals. This was done because the pipe that touches the fire can melt away so it’s better to make this part replaceable.
Instead of making a large wheel and belt assembly to step up the speed of rotation, I opted for a 75 cm long bow. I made a frame to hold the rotor in place consisting of two stakes hammered into the ground with a socketed cross bar lashed on to hold the top of the rotor. I made bark fibre cordage and tied the end to a stick. I then looped the cord around the rotor and held the other end in the same hand holding the stick. I then pushed and pulled the bow causing the rotor to spin rapidly, forcing air into the fire.
I made a simple mud furnace for the blower. Then I collected orange iron bacteria from the creek (iron oxide), mixed it with charcoal powder (carbon to reduce oxide to metal) and wood ash (flux to lower the melting point) and formed it into a cylindrical brick. I filled the furnace with charcoal, put the ore brick in and commenced firing. The ore brick melted and produced slag with tiny, 1mm sized specs of iron through it. My intent was not so much to make iron but to show that the furnace can reach a fairly high temperature using this blower. A taller furnace called a bloomery was generally used in ancient times to produce usable quantities of iron and consumed more charcoal, ore and labour.
This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows. The cords for this device wear out often so a number of back up cords should be kept handy for quick replacement. In summary, this is an easy to make device that solves the problem of supplying forced combustion air required for high temperature furnaces and forges.
