Andromeda Project Home The Violent Universe Please note that this course is self-paced and you can enroll at any time. The course itself is 9 weeks long and certificates are generated and distributed to learners who meet the 50% requirement every 3 months. The next scheduled dates for certificates to be released are 1st March 2015 and 1st June 2015. Interested in exploring the deadliest and most mysterious parts of our universe? Or, investigating black holes, which warp the very fabric of space-time around them? We will look at what we know about these objects, and also at the many unsolved mysteries that surround them. This course is designed for people who would like to get a deeper understanding of astronomy than that offered by popular science articles and television shows. You will need reasonable high-school level Maths and Physics to get the most out of this course.
Orproject Unveils Giant Bubbles Filled With Fresh Air for Polluted Beijing Beijing’s record-breaking air pollution has spurred officials and designers to come up with innovative solutions – and the architects at London-based Orproject recently proposed the creation of gigantic Bubbles filled with fresh air! The inflatable spaces would contain parks and botanical gardens that provide fresh air to residents sick of choking on the city’s ever-present smog. Orproject is an innovative design practice founded in 2006 that tends to explore advanced geometries with an ecological leaning. Bubbles is based on a lightweight structural system developed to mimic butterfly wings and the veins of leaves. The system utilizes a material known as ETFE, which is the same material used in China’s National Swim Center at the Beijing Olympics in 2008. This transparent and stretchy plastic could be used to create wonderful domes that allow light in while protecting inhabitants from pollution. + Orproject Via Co.
: Pluto Time Pluto orbits on the fringes of our solar system, billions of miles away. Sunlight is much weaker there than it is here on Earth, yet it isn't completely dark. In fact, for just a moment near dawn and dusk each day, the illumination on Earth matches that of noon on Pluto. We call this Pluto Time. If you go outside at this time on a clear day, the world around you will be as bright as the surface of Pluto at noon. Learn More It's always Pluto Time somewhere, and NASA wants to see your view. Next Month, New Horizons will become the first spacecraft to have a close encounter with Pluto. #PlutoTime: we can't wait to see what it looks like in your world.
nellátó város tervei Kínában Önellátó város tervei Kínában Vajon lehet-e egyesíteni város és vidék előnyeit, vagyis meg lehet-e oldani, hogy a város is önellátó legyen? Erre a kérdésre született a szokatlan látképű város terve Kínában. A nagyvárosok általános jellemzője, hogy szinte teljes mértékben elkülönülnek azoktól a gazdaságoktól, amelyek ellátják azokat élelmiszerrel. A Kínában tervezett különleges futurisztikus külsejű város alapötlete ennek az ellentmondásnak a feloldása, ennek érdekében egy 45 villából álló közösséget építenének fel hatalmas kertekkel. A projekt olyan fenntartható technológiákkal büszkélkedhetne, mint a Nap útját követő és azonnal szinkronizálódó automatikus-hőszabályozók, szélenergiát hasznosító szerkezetek, valamint egy intelligens energiahálózat, ami friss levegőt, zöld területet és egészséges termékeket egyszerre biztosít.

New paper shines light on little-understood process in astronomy A paper coauthored by Tom Maccarone, a Texas Tech University associate professor in the Department of Physics, studies one of the most important but least understood processes in astronomy: accretion, or the growth in mass of an object by gravitationally collecting material from its surroundings. The article, titled "Astrophysical accretion is a universal process in objects from proto-stars to supermassive black holes," is published in the most recent issue of the journal Science Advances. "In our paper, we discovered a relationship that spans the range of different types of accreting objects, from proto-stars, much like our sun was at its time of birth, to white dwarfs to supermassive black holes with a billion times the mass of the sun located in galaxies millions of light-years away," Maccarone said. "In these systems there is some characteristic timescale for the variability – typically the large brightenings and fadings occur with that timescale.
