Astrónomos descubren “estrellas imposibles” | Desde la Redacción Dos estrellas de tipo enanas rojas que orbitan entre sí cada 2,5 horas, luego se fundirán en una. / Space.comPor Miguel Artime - Lo que los astrónomos acaban de encontrar en nuestra galaxia, la Vía Láctea, es algo que hasta ahora parecía imposible. Estrellas gemelas orbitándose la una a la otra en un ciclo vertiginoso completo de menos de cuatro horas. Hasta ahora, los científicos creían que algo así era imposible, y eso que a pesar de que nuestro sol carece de compañera, casi la mitad de las estrellas de nuestra galaxia podrían formar parte de un sistema binario. Empleando el Telescopio Infrarrojo del Reino Unido (UKIRT) situado en Hawaii, los astrónomos descubrieron cuatro parejas de "estrellas imposibles". Por norma, se creía que si una estrella se formaba demasiado cerca de otra, las dos estrellas se mezclarían rápidamente formando un único astro mayor. Lo que no saben explicar los astrónomos es cómo pudieron reducir su tamaño las órbitas de estas binarias. Fuente Yahoo!
Thunderbolts home The Internet map The 5th state of matter Summary: beautiful filament-systems are often shown by the astonishing development of the modern astronomy. Most of these filaments have an exact circular cross section. Filaments have the same interesting characteristics from a diameter of 0.01 mm to that of many 1000 of light-years. Filaments are incorrectly seen to be of plasma, however, particles move in only one direction in them, often against gravity. Key words: Acceleration of particles, Bose-Einstein condensate, corona, corona problem, cosmic rays, fifth state of matter, filament, flux tube, forbidden lines, heat-motion, hypernova, jet, lightning, magnetic tube, non-thermal-phenomena, pinch-effect, plasma, solar dynamo, state of matter, supernova, temperature-scale. Ice is transformed to water at 0°C when the energy of its molecules (particles) increases. Fig. 1 The temperature scale.

Gödel’s Lost Letter and P=NP Is It Time To Stop Malware—Forever? Rich DeMillo is a theorist who has also been: the head of all computer science research at Bellcore/Telcordia, the first Chief Technology Officer of HP, and the Dean of the College of Computing at Georgia Tech. All this and he has also made important contributions to theory, software engineering, and security. Today I want to talk about computer malware. Just having a name—malware—for worms and viruses is a problem. We tend to name things that are important, or is it things become important when we name them? I’m as mad as hell, and I’m not going to take this anymore! In the beginning there was ARPANET. I recall watching with envy my colleagues, like Anita Jones, check her ARPANET account for messages. Eventually, those of us on the outside, those of us without ARPANET accounts, decided to act. DeMillo, who is a great and fast writer, sat down and wrote a draft of the proposal in a day or two. Larry was instantly upset: he said he had no idea what was happening. Why is There Malware? . .
What You'll Wish You'd Known January 2005 (I wrote this talk for a high school. I never actually gave it, because the school authorities vetoed the plan to invite me.) When I said I was speaking at a high school, my friends were curious. What will you say to high school students? I'll start by telling you something you don't have to know in high school: what you want to do with your life. If I were back in high school and someone asked about my plans, I'd say that my first priority was to learn what the options were. It might seem that nothing would be easier than deciding what you like, but it turns out to be hard, partly because it's hard to get an accurate picture of most jobs. But there are other jobs you can't learn about, because no one is doing them yet. And yet every May, speakers all over the country fire up the Standard Graduation Speech, the theme of which is: don't give up on your dreams. What they really mean is, don't get demoralized. Which is an uncomfortable thought. Upwind Ambition Corruption Curiosity
LA FARSA DE LA HOMOSEXUALIDAD EN LA ANTIGUA GRECIA « Todo está relacionado Está por todas partes. Se menciona por encima en tertulias televisivas, se escribe en libros de texto, está en boca de profesores de universidad, e Internet lo repite incesantemente, incluso en la Wiskypedia ―como por ejemplo en este “artículo” (por llamarlo de alguna manera) sobre la pederastia en Grecia. Todo el mundo lo parafrasea, se ha convertido en un “meme”, un eslogan que las masas repiten sin pensar, de modo similar al famoso “todos somos iguales”. Se han vertido toneladas y toneladas de basura sobre la historia griega, e innumerables autorzuelos del tres al cuarto han desarrollado páginas y páginas dando por sentado que la mentira es cierta. ¿A qué nos referimos? A que hoy todo el mundo asume que los antiguos griegos eran una panda mariconas redomadas. En otro artículo quedó demostrada la falsedad del mito de que los griegos fuesen “mediterráneos”. ¿Dónde está, pues, el problema griego? Dicho todo esto, comencemos a desmenuzar el mito. - Euryproktos: culo abierto. Afrodita
NASA and university researchers find a clue to how life turned left | Science Wire “Our analysis of the amino acids in meteorite fragments from Tagish Lake gave us one possible explanation for why all known life uses only left-handed versions of amino acids to build proteins,” said Dr. Daniel Glavin of NASA’s Goddard Space Flight Center in Greenbelt, Md. Glavin is lead author of a paper on this research to be published in the journal Meteoritics and Planetary Science. This is an artist’s concept of excess left-hand aspartic acid created in asteroids and delivered to Earth via meteorite impacts. The line at the bottom is a chromatogram showing that left-hand aspartic acid (tall peak in the center, with diagram of left-hand aspartic acid molecule on top) was four times more abundant in the meteorite sample than right-hand aspartic acid (smaller peak to the left, with right-handed aspartic acid molecule on top). Isotopes are versions of an element with different masses; for example, carbon 13 is a heavier, and less common, variety of carbon.
Content Creation: Why You Should Stop Thinking Customer First Thinking customer first creates a barrier when conceptualizing ideas for content creation. By zeroing in on the word “customer”, you face the danger of typecasting people into a singular role that only exists in your own personal narrative. This is a limiting approach that overlooks an important fact: your customer is more dynamic than someone in need of a particular product or service. By adopting an outward looking approach to how you understand and ultimately reach your audience, you will start creating the content that fits into the story that matters, your customers’. Your Content: Become Part of Someone’s Story Look at great stories throughout history. You Want People to Feel Like You Know Them According to Dev Patnaik, fostering empathy is a key component to reaching this position. Empathy can be a catalyst for, as well as a major theme in your content. How can this be done? Let them see you. Engaging With Different People & Diversifying Your Content This is valuable insight.
a guided tour Getting started with xmonad This is a guided tour of the core features of the xmonad window manager, allowing you to gain an understanding of the motivation, and use of a tiling window manager, and learn how to achieve the kind of screen configuration you want, simply and easily. Starting xmonad We'll assume you've been able to build xmonad from hackage (or from your package system). If not, seeing the build instructions. You can then start xmonad directly from your .xsession or .xinitrc file, by executing it as so: # .xsession xrdb -merge .Xresources xpmroot ~/background.xpm & $HOME/bin/xmonad Note the use of xpmroot to set a background image. Opening clients When you start xmonad, without launching clients, you'll be presented with an empty screen: Let's start some clients, to fill the screen. xmonad uses the mod1 key (alt) by default, and we can start by launching a terminal with mod-shift-return. Let's open up another terminal mod-shift-return: Layout modes Moving focus and again mod-comma:
A selection from "Israel's Tribes Today" by Steven M A selection from "'s Tribes Today" by Steven M. Collins, chapter one, pages 31 to 49: The Asian “Sacae” Become the European Saxons Not all of the migrating Parthians and Scythians came to be known as Goths or Germans. “The Saxons were a German or Teutonic, that is, a Gothic or Scythian tribe; and of the various Scythian nations which have been recorded, the , or Sacae, are the people from whom the descent of the Saxons may be inferred...The ...were an important branch of the Scythian nation. The Scythian/Parthian people had been known as the Sacae or Saka for over a millennium. The Scythian/Sacae origin of the Germans and Saxons has been known for centuries. “...that the Germans are called Scythians, we gather not only out of...Strabo...but also out of Pliny. Consider also Sharon Turner’s comment in the 1836 book, The History of the Anglo-Saxons: The Romans had a custom of naming leaders after the enemies they fought. R.H. These dates are extremely significant. D.V. How true!
10 Lesser-Known Germanic Tribes Humans The Germanic tribes during the Roman Empire have been, more or less, categorized into the much more well-known groups (Goths, Vandals, etc.) who did manage to burn and sack Rome. The truth is that these “barbarians” were much more diverse and varied; their existence was more fluid than what the textbooks usually tell us. This list offers a glimpse of a few of the lesser-known Germanic tribes, listed as a footnote to the greater and more glorified barbarians that helped push Europe to the middle Ages. This tribe has only been mentioned in passing by Tacitus, in his work De Germania. The tribe’s name came from the Proto-Germanic word harjaz, which means “warrior.” Modern scholars have connected this tribe to the Viking’s Odin-related practices and beliefs: “Einherjar” (warriors who died during battle and thus will fight in Ragnarök), the Wild Hunt and the berserkers, through etymology. The Harii have no known descendants. Hessians were the supposed descendants of the Chatti.
From scrubbing floors to Ivy League: Homeless student to go to dream college It's before sunrise, and the janitor at Burns High School has already been down the length of a hallway, cleaning and sweeping classrooms before the day begins. This particular janitor is painstakingly methodical, even as she administers a mental quiz on an upcoming test. Her name is Dawn Loggins, a straight-A senior at the very school she cleans. On this day, she maneuvers a long-handled push broom between rows of desks. The worst, she says, is snuff cans in urinals. With her long, straight dark blonde hair and black-rimmed glasses, Dawn looks a bit like Avril Lavigne. She was homeless at the start of the school year, abandoned by her drug-abusing parents. She's grateful for the work. For now, there's still work to be done. Growing up without electricity Dawn grew up in a ramshackle home with no electricity and no running water. "We would get water jugs and fill them up at the park, using the spigots in the bathroom. She confided in a staff member at school. Abandoned by parents
