Seres humanos destacados: los Hunzakuts. Hunza está situado en un valle remoto que tiene unos 300 Km. de largo por sólo uno y medio de ancho, a una altura de 300 m y completamente rodeado de picos montañosos.

Seres humanos destacados: los Hunzakuts

Estos picos llegan a los 7.000 m de altura y pertenecen a la cordillera Karakoram, más conocida en occidente por Himalaya o el «techo del mundo». Hunza, que está en el extremo nordeste de Pakistán está en un paso solamente de Cachemira controlado por Pakistán, de la India, de Afganistán, de Rusia y de la China. El único acceso al valle es a través de Rawalpindi, la nueva capital de Pakistán. Desde ahí, 45 minutos de vuelo le llevarán a Gilgit, 375 millas al norte.

Este vuelo es uno de los más peligrosos del mundo ya que la avioneta ha de cruzar por una serie de pasos montañosos muy traicioneros. Las evaluaciones de longevidad que los visitantes extranjeros atribuyen a los hunzukuts varían considerablemente, siendo la estimación más elevada 150 años. Fuerte Altit, a orillas del río Hunza.

Einstein's Zurich Notebook

Norton Center for Philosophy of Science Department of History and Philosophy of Science University of Pittsburgh This page at www.pitt.edu/~jdnorton/Goodies For more images and much more commentary on the Zurich Notebook, look here. Setting the Stage In the half century and more of Einstein's work in science, one discovery stands above all as his greatest achievement. It is his general theory of relativity.

This discovery of this theory is somehow more than mere science. Opening the Notebook Let us start at the beginning. Inside the "Relativity" cover are a few rough sketches shown below. What of the square and rectangles with the cross-hatching? Electrodynamics in Four Dimensions This inside cover was recreational. Line Element of General Relativity for the First Time The development continues for 13 pages recounting notions in electrodynamics and thermal physics. This is quite possibly the first time Einstein has written down this expression.

(Before It's News) Anything and everything anytime The Sentinelese (also Sentineli, Senteneli, Sentenelese, North Sentinel Islanders) are one of the Andamanese indigenous peoples and one of the most uncontacted peoples of the Andaman Islands, located in India in the Bay of Bengal.

Lost Tribe On Small Island In The Indian Ocean remain virtually untouched by modern civilization.

They inhabit North Sentinel Island which lies westward off the southern tip of the Great Andaman archipelago. They are noted for vigorously resisting attempts at contact by outsiders. The Sentinelese maintain an essentially hunter-gatherer society subsisting through hunting, fishing, and collecting wild plants; there is no evidence of either agricultural practices or methods of producing fire. The present population of the Sentinelese is not known with any great degree of accuracy. On previous visits, groups of some 20–40 individuals were encountered regularly.

List of long-living organisms

This is usually defined as: Biological immortality[edit] If the mortality rate of a species does not increase after maturity, the species does not age and is said to be biologically immortal. There are many examples of plants and animals for which the mortality rate actually decreases with age, for all or part of the life cycle.[1] If the mortality rate remains constant, the rate determines the mean life-span. Other species have been observed to regress to a larval state and regrow into adults multiple times. The Hydrozoan species Turritopsis dohrnii is capable of cycling from a mature adult stage to an immature polyp stage and back again. Revived into activity after stasis[edit] Various claims have been made about reviving bacterial spores to active metabolism after millions of years.

Sailing stones. Sailing stones, sliding rocks, and moving rocks all refer to a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention.

Sailing stones

Tracks from these sliding rocks have been observed and studied in various locations, including Little Bonnie Claire Playa in Nevada,[1] and most notably Racetrack Playa, Death Valley National Park, California, where the number and length of tracks are notable. At Racetrack Playa, these tracks have been studied since the early 1900s, yet the origins of stone movement are not confirmed[2] and remain the subject of research for which several hypotheses[3] exist. The stones move only every two or three years and most tracks develop over three or four years. Stones with rough bottoms leave straight striated tracks while those with smooth bottoms tend to wander.

Stones sometimes turn over, exposing another edge to the ground and leaving a different track in the stone's wake. Description[edit]
