„Putem integra vîrstnicii ascultîndu-le mărturiile” - interviu cu antropologul Frédéric Balard

Frédéric Balard este membru al echipei Demografie şi Sănătate din Montpellier (Franţa) din 2003. Este Doctor în antropologie, cu teza „Cei mai vîrstnici dintre vîrstnici: o cultură vie la porţile morţii”.

Aţi publicat un articol numit : „Păstrarea identităţii la vîrste înaintate cu scopul de a îmbătrîni bine : între rezistenţă şi dezangajare”. Identitatea persoanei rămane neschimbată de-a lungul timpului sau putem vorbi de o identitate aparte a vîrstnicului ? Şi, întrucat aţi studiat indeaproape nonagenarii, se schimbă identitatea de-a lungul diferitelor etape ale îmbătrînirii ?

Antediluvian Kings

"Every king springs from a race of slaves, and every slave had kings among his ancestors" – Plato

Adom Abayomi, the current pharaoh of ancient Egypt, was watching the last of his pyramid being built. Even in the hot weather he still wore a heavy gold brace around his neck, never sparing any expense to show his wealth and power. His face bore a stern expression, but inside he was overjoyed, his tomb was as perfect as he'd imagined.

Codul de legi al lui Hammurabi

Desi inscaunat regele Babilonului la doar 25 de ani, Hammurabi cel Mare si-a lasat o amprenta puternica asupra istoriei Orientului Apropiat din vremurile secolului 18 i.Hr. Si-a extins rapid aria de influenta cucerind orasele-stat din apropiere, Isin, Uruk si Ur, apoi regatele asirian, akkad si sumerian pentru a controla intreaga Mesopotamie, regiunea fertila dintre fluviile Tigru si Eufrat, numita si “Leaganul civilizatiei omenirii”. A condus realizarea primelor lucrari de infrastructura la scara mare in agricultura in campiile din Mesopotamia, construirea de temple pentru strangerea populatiilor in jurul religiei si a sustinut dezvoltarea culturii in zona.

Ирландцы стали свидетелями падения необычного космического объекта

МОСКВА, 22 сен - РИА Новости. Жители Ирландии в пятницу вечером стали свидетелями полета необычайно яркого болида - очень яркой "падающей звезды".

Астрономы-любители полагают, что это мог быть вход в атмосферу отработанной ступени ракеты-носителя, однако они озадачены необычным направлением полета болида - с востока на запад, тогда как все искусственные космические объекты летят в одну сторону с направлением вращения Земли с запада на восток.

Inelia Benz ~ Did You Hear? We Can Do It Today

The information in this article is highly empowering, and reveals deeply known, yet forgotten, facts about our true natures. Feel free to share it, email it, and post it to anyone you feel it will empower. Although simple, it goes to the core of how the Light/Dark Paradigm has been able to function for so long and how we can consciously move back to our true natures of Light/Love, bringing in the New Paradigm with us into what we know as a “physical reality”.

Most of us have heard of the “Tower of Babel”. If you haven’t, the biblical story goes like this:

Planetă, distrusă de propriul soare

Astronomii au confirmat, folosind telescopul spaţial Kepler, descoperirea unei planete, cu o mişcare de revoluţie scurtă, asemenea lui Mercur, care a intrat în ultimul stadiu al vieţii sale. Această planetă este practic distrusă de soarele în jurul căruia orbitează.

Acest obiect s-a apropiat atât de mult de steaua în jurul căreia orbitează încât are nevoie doar 15,7 ore pentru a o înconjura. Temperatura planetei a crescut până la 4400 K. Rezultatul fiind o coadă, asemeni unei comete ce ţâşneşte din planetă, luând odată cu ea o cantitate semnificativă din suprafaţa planetei.

Large Monolithic Imager sees first light on the Discovery Channel Telescope

The Large Monolithic Imager (LMI), a camera built at Lowell Observatory and funded by the National Science Foundation (NSF), recently took a set of first-light images on Lowell's 4.3-m Discovery Channel Telescope (DCT).

At the heart of the LMI is the largest charge-coupled device (CCD) that can be built using current fabrication techniques and the first of its kind to be made by e2v.

The 36-megapixel CCD's active surface is 3.7 inches on a side. The LMI's ability to provide much more accurate measurements of the faint light around galaxies separates it from cameras that use a mosaic of CCDs to produce images.

Single-atom writer a landmark for quantum computing

A research team led by Australian engineers has created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future. In a landmark paper published in the journal Nature, the team describes how it was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorus atom embedded in a silicon chip.

"For the first time, we have demonstrated the ability to represent and manipulate data on the spin to form a quantum bit, or 'qubit', the basic unit of data for a quantum computer," says Scientia Professor Andrew Dzurak. "This really is the key advance towards realising a silicon quantum computer based on single atoms."

Black Hole Roundup

Black holes, black holes, and more black holes. In the past few weeks I’ve been thinking, talking, and even dreaming about black holes (yes really, somnolent thoughts seem well suited to these fantastic objects). Mostly this has been an effect of my book Gravity’s Engines hitting the shelves, but it’s also because barely a day seems to go by without some new piece of astrophysical research on these most dense and fantastic objects. Here’s a quick round up of a couple items.

A new survey containing the locations of about 2.5 million supermassive black holes was released a couple weeks back that used the full sky map obtained with NASA’s WISE (Wide-Field, Infrared Survey Explorer) mission to track down the pinpoints of thermal radiation from dust enshrouded holes in distant galaxies.
