12:07 AM | El Nino Project (Part 8)
This time I’d like to compare a different paper on climate networks: • Y. Berezin, A. Gozolchiani, O. Guez and S. Havlin, Stability of climate networks with time, Scientific Reports 2 (2012). The goal of this paper is to see how stable over time climate networks over time. They divide the world into 9 zones: […]

http://t.co/hgbABOxUlm by @ulaulaman about #nobelprize2014 on #physics #led #light #semiconductors Created with SketchBookXOne of the first classifications that you learn when you start to study the behavior of matter interacting with electricity is between conductors and insulators: a conductor is a material that easily allows the passage of electric charges; on the other hand, an insulator prevents it (or makes it difficult). It is possible to characterize these two kinds of materials […]
