The Zeta function ζ(s) is defined as above, for example : ζ(2) = 1/12 + 1/22 + 1/32 ... = π2 / 6. This converges for s>1 (i.e. tends towards a limit), but diverges for anything else. The Riemann Zeta function extends this range to allow us to compute the result for any complex number. The Riemann Hypothesis claims that the … Continue reading Zeta #AtoZAprilChallenge

Yawpa #AtoZAprilChallenge
Yawpa is the Hopi name for the Mockingbird. "The mockingbird fluttered around the bamboo, calling out, 'Pashumayani! Pashumayani! Be careful! Be careful!' This is the way the people departed from the Lower World" (from The Four Worlds: the doorway to the Fourth World, in 'The Fourth World of the Hopis', by Harold Courlander.) From Wikipedia, … Continue reading Yawpa #AtoZAprilChallenge

nascent love like – the new moon turns its face away Beginnings glow, and often fail to spark much longer. When we met we knew a few things, that experience was not measured in promiscuity, that love is for most of us a mirage, that looks and bodies change – over time – and “bien … Continue reading X #AtoZAprilChallenge
Walpi #AtoZAprilChallenge
We leave Flagstaff on the I89 direction North. Soon we see the sign for the Sunset Crater and Wupatki, but today we are heading further up in the Navajo country. Shortly after Cameron we cross the Little Colorado River, theatre of many migrations over two millennia of Native American history. We turn off East, toward Tuba City, named … Continue reading Walpi #AtoZAprilChallenge
Vanished #AtoZAprilChallenge
Dedicated to the Native American tribes, victims of the greatest genocide in history, who knew agriculture, and the art of living, when Europe was starving, crawling in medieval darkness. He stands on the red rocks, alone with ghosts, his sight on the painted horizon. Slowly they appear in his vision: the millions, slaughtered by disease, hunger, … Continue reading Vanished #AtoZAprilChallenge
Unlucky #AtoZAprilChallenge
Captain Le Guen was a Muslim, a faith he had inherited from his mother, who, as a young child, had been rescued by the Franj from her burning village in the Aurès, during that war. He had been born in Qimper in Brittany, where Le Guen père, an officer in the Navy, had wanted to … Continue reading Unlucky #AtoZAprilChallenge
Trinken #AtoZAprilChallenge
It is a threat, and a pleasure, perhaps the most pernicious risk to mankind since the Black Death… Yet, how could we give up those marvels of nature, human skills and poetic evocations? Just think: from the Old World to the New, Pino Grigio, Montbasillac, Saint-Emilion, Burgundy, Champagne, the marvellous Australians, the North-Californians, the Cahors, the sunshine from … Continue reading Trinken #AtoZAprilChallenge
Sipapuni #AtoZAprilChallenge
When a stranger comes to the village, feed him. Do not injure one another, because all beings deserve to live together without injury being done to them. When people are old and cannot work anymore, do not turn them out to shift for themselves, but take care of them. Defend yourselves when an enemy comes … Continue reading Sipapuni #AtoZAprilChallenge
Rendezvous #AtoZAprilChallenge
For the first time the voice he heard, in his sleep, was not Melissa’s. The woman introduced herself as Gabrielle, Melissa’s teacher, and proceeded to explain where he would find her, in clear, geographical precision, courteous, but leaving no doubt that he was expected to attend. The message was delivered without preamble, as a matter … Continue reading Rendezvous #AtoZAprilChallenge
Q #AtoZAprilChallenge
"Q", authored by the Italian writers' collective Luther Blissett, now morphed to "Wu Ming", tells the story of Gert-from-the-Well, a young student from Saxony, in the aftermath of the monk Martin Luther's ninety five theses, pinned on the door of the Wittenberg cathedral church in 1517. I am on my second reading of Q, and have … Continue reading Q #AtoZAprilChallenge
