"Marcher c'est penser hors des sentiers battus, Reflexions croisées sur la nouvelle pérégrination de l'humanité" ou "Comment le nomadisme est-il devenu l'une des plus puissantes idéologies de la globalisation ?"
Alors prenez l'expérience d'une journée de marche. La lenteur de la marche, sa régularité, cela rallonge considérablement la journée. Et en ne faisant que mettre un pied devant l'autre, vous verrez que vous aurez étiré démesuremment les heures. De sorte qu'on vit plus longtemps en marchant, pas au sens où cela rallongerait votre durée de vie, mais au sens où, dans la marche, le temps ralentit, il prend une respiration plus ample ... Il y dans la contemplation des paysages par le marcheur, une dimension de gratitude, sans qu'on sache exactement si c'est le marcheur qui se récompense par une intensité supérieure offerte au seul marcheur ... Si l'on redécouvre aujourd'hui les bienfaits de la marche, c'est que l'on recommence à ressentir que la vitesse, l'immédiateté, la réactivité peuvent devenir des aliénations. On finit dans nos vies ultramodernes, par n'être plus présent à rien, par n'avoir plus qu'un écran comme interlocuteur? Ce qui fait l'actualité critique de la marche, c'est qu'elle nous fait ressentir la déconnexion comme une délivrance." Frédéric Gros, Professeur de philosophe politique à l'universié Paris-XII et à l'Institut d'études politiques de Paris, "Marcher, une philosophie", Carnet du Nord, 2009. in Le Monde du 25/06/11.

Roundworm's brain
"In an laboratory overlooking New York's East River, Dr. Cornelia Bargmann watches two colleagues manipulate a microscopic roundworm. They have trapped it in a tiny groove on a clear plastic chip, with just its nose sticking into the channel. Pheromones-signaling chemicals produced by other worms- are being pumped through the channel, and the researchers have genetically engineered two neurons in the worm's head to glow bright green if a neuron responds.
These ingenious techniques for exploring a tiny animal's behavior are the fruit of many years' work by Dr. Bargman's and other labs. Despite the roundworm's lowlines on the scale of intellectual achievement, the study of its nervous system offers one of the most promising approaches for understanding the human brain, since it uses much the same working parts but is around a million times less complex. Caenorhabditis elegans, as the roundworm is properly know, is a tiny, ransparent animal just a millimeter long. In the nature, it feed on the bacteria that thrive in rottng plants and animals. It is a favorite laboratory organism for several reasons, including the comparative simplicity of its brain, which has just 302 neurons and 8 synapses, or neuronto-neurons connections. Theses connections are pretty much he same from one individual to another, meaning that in all worms the brain is wired up in essentially same way. Such a system should be considerably easier to understand han the human brain, a structure with close to 100 million neurons, 100 miles of biological wiring and 100 trillion synapses ...

New thinking
Non c'è più di maestro per oggi quando vediamo le media svillupare la conoscenza di questi giorni quà ... Come si impara ancora qualche cose sulla vita ? Mai pensare in lungo ma sempre portare presto informazione su informazione, senza vedere più lontano ... Creare solamente dei produtti di consomazione da utilisare in poco tempo, per dare tra l'ultima tecnologia impressione di verità ultima sul mondo. Dov'è passata la sapienza ?

Crazy
Il 11 giugno ho ritrovato già da qualche giorni questa scrittura che si era fermata, perchè ? Non saro mai che cosa è stata succedendo ma la paura di avere scritto il peggio stava venando nel subcosciente sempre come una minaccia ... Questa quà poteva farmi chiamare la giustizia, ma laquale ? Una giustizia sociale, una giustizia politica, una giustizia che non esiste ? Perchè l'analisa dei movimenti socio-politici non esiste veramente ! ...
« Je suis celui qui veut éternellement le mal mais toujours fait le bien » (épitaphe tirée du Faust de Goethe) come nel libro '"Le Maître et Marguerite " di Mikhaïl Boulgakov !
