Meteorite in Peru.

This afternoon scientists which went to the town of Carancas in the Region of Puno, Peru, have confirmed that the glowing object which fell from the sky on Saturday afternoon was indeed a meteorite. Health Directorate reported that doctors and nurses found it necessary to establish auxiliary medical tents near the health center in Carancas because at least 150 people had been seen after having stated they had dermal injuries, were dizzy, nauseous or vomiting and at least seven police officers were affected after they collected samples from the landing site of what is thought to be meteorite.

Scientists confirmed that the meteorite that caused a 17 meter (55 foot) wide and 5 meter (16 foot) deep crater in Puno, Peru was a chondrite meteorite. The water in the crater is to be drained and several teams of scientists from different countries will take samples from the crater itself and from surrounding areas. We just have to wait for the scientists inal decision what it was exactly.

A Natural History of Zero.

The Nothing That Is: A Natural History of Zero was an international best-seller, translated into ten languages. The Times called it “elegant, discursive, and littered with quotes and allusions from Aquinas via Gershwin to Woolf” and The Philadelphia Inquirer praised it as “absolutely scintillating.”
In this delightful new book, Robert Kaplan, writing together with his wife Ellen Kaplan, once again takes us on a witty, literate, and accessible tour of the world of mathematics. Where The Nothing That Is looked at math through the lens of zero, The Art of the Infinite takes infinity, in its countless guises, as a touchstone for understanding mathematical thinking. Tracing a path from Pythagoras, whose great Theorem led inexorably to a discovery that his followers tried in vain to keep secret (the existence of irrational numbers); through Descartes and Leibniz; to the brilliant, haunted Georg Cantor, who proved that infinity can come in different sizes, the Kaplans show how the attempt to grasp the ungraspable embodies the essence of mathematics. The Kaplans guide us through the “Republic of Numbers,” where we meet both its upstanding citizens and more shadowy dwellers; and we travel across the plane of geometry into the unlikely realm where parallel lines meet. Along the way, deft character studies of great mathematicians (and equally colorful lesser ones) illustrate the opposed yet intertwined modes of mathematical thinking: the intutionist notion that we discover mathematical truth as it exists, and the formalist belief that math is true because we invent consistent rules for it.
“Less than All,” wrote William Blake, “cannot satisfy Man.” The Art of the Infinite shows us some of the ways that Man has grappled with All, and reveals mathematics as one of the most exhilarating expressions of the human imagination.

The Largest Photo with Camera Obscura

Activists of well known Legacy Project didn’t waste their time this summer. They used Camera Obscura to create the world’s largest photograph. The image is a 28-foot-tall, 108-foot-wide black-and-white negative of a runway. The Great Picture is expected to establish the new Guinness World Records categories of largest camera and largest photograph, the organizers say. The picture is a throwback to the early days of photographic technology.

I’ve found it looks wonderful. And that is not because this photograph is the biggest one but because I’ve got tired from multitude digital imagines I guess that all of them (never mind it is bad or perfect) look like the same, even after working with digital photos in Photoshop it don’t afford me pleasure already.
However I love this picture and applaud to fellows which got it and to their patience and staying-power:-)

By the way for those who don’t know what is a camera obscura? It (lat. dark chamber) was an optical device used in drawing, and one of the ancestral threads leading to the invention of photography, today’s photographic devices are still known as “cameras”.
The principle of the camera obscura is demonstration of reak reflection with a rudimentary type, just a box (which may be room-size) with a hole in one side, that lets the light from only one part of a scene to pass through the hole and strike a specific part of the back wall. The projection is made on paper on which an artist can then copy the image. You can try, it’s easy.

Archaeology news.

As National Geographic reports Venetian archaeologists have discovered ancient mass graves containing more than 1,500 victims on a small island in Italy’s Venetian Lagoon.
“When plague struck the town, everybody sick or showing any suspect symptom were restricted on the island until they recovered or died,” said Luisa Gambaro, an anthropologist of the University of Padua. “We were called to attend the excavations, study the site, and rescue remains and artifacts,” said Vincenzo Gobbo, an archaeologist of the University Ca’ Foscari of Venice working with the Archaeological Superintendence of Veneto “In the last three years we collected more than 1,500 corpses and 150 boxes of artifacts,” he added. “We estimate there are still thousands of skeletons buried beneath every meadow in Lazzaretto Vecchi.”
