Droit aux buttes Jardins en buttes à l'écocentre du périgord On les voit fleurir un peu partout, elles représentent une vraie révolution dans notre relation au sol et notre façon de cultiver. Symboles par excellence de l’agroécologie mais surtout de la permaculture (avec la poule), elles n’en sont pourtant qu’un élément parmi d’autres. Elles représentent l’antithèse du jardin à la papa : un espace riche et vivant, résistant à la sécheresse, à l’excès de pluie, un espace multidimensionnel extrêmement productif qui peut même être auto-fertile. C’est Emilia Hazelipp qui semble avoir importé la culture sur butte en France. Mais quels sont les avantages de cette culture étrange qui demande pourtant un gros travail de mise en place? tout d’abord, elle évite de se baisser. - limiter l’enherbement, - limiter l’évaporation de l’eau et donc de presque supprimer l’arrosage (hors plantation bien sûr), Le non travail du sol. crédits Robert Morez, cliquez sur l’image pour l’agrandir Creuser une tranchée à 35 cm.

7th Grader mimics Nature 13 year old copies Nature to Improve Solar Performance Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches. Aidan realized the tree branches and leaves had a mathematical spiral pattern that could be shown as a fraction. Aidan's backyard in Northport, NY. The 7th grader next wondered why nature used such a pattern? Aidan discovered that the Fibonacci pattern helps deciduous trees, in higher latitudes, efficiently track the Sun and collect the most sunlight even in the thickest forest, on the cloudiest days. The American Museum of Natural History has awarded Aidan a Young Naturalist Award for 2011. See the detailed description of his discoveries on the Museum's website: *www.amnh.org In late 2012, early 2013, Aidan builds a larger model: Postscript: Many have questioned why Aidan did not measure power output from the solar cells, instead he only measured voltage, without a load attached ("open circuit").

Darknet - The Darkside - Ethical Hacking, Penetration Testing & Computer Security Emerald Tablet An imaginative 17th century depiction of the Emerald Tablet from the work of Heinrich Khunrath, 1606. The Emerald Tablet, also known as the Smaragdine Table, or Tabula Smaragdina, is a compact and cryptic piece of Hermetica reputed to contain the secret of the prima materia and its transmutation. It was highly regarded by European alchemists as the foundation of their art and its Hermetic tradition. Textual history[edit] The text of the Smaragdine Tablet gives its author as Hermes Trismegistus ("Hermes the Thrice-Greatest"), a legendary Hellenistic[1] combination of the Greek god Hermes and the Egyptian god Thoth.[2] Despite the claims of antiquity, it's believed to be an Arabic work written between the sixth and eighth centuries.[3] The oldest documentable source of the text is the Kitāb sirr al-ḫalīqa (Book of the Secret of Creation and the Art of Nature), itself a composite of earlier works. The tablet text[edit] Newton's translation[edit] Theatrum Chemicum translation[edit] C.G.
