10 anos para contar
Não poderia deixar de mencionar o lançamento do livro do meu irmão caçula. "10 anos para contar" é uma coleção de poesias escritas pelo André durante a sua adolescência. O livro acabou de ser lançado mas, por enquanto, está disponível somente para compra pela internet no site da editora.Higgs Boson at FermiLab?
CDF precision measurement of W-boson mass suggests a lighter Higgs particle. The Fermilab press release from Jan 8th can be found here."Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (January 8, 2007) the world's most precise measurement by a single experiment of the mass of the W boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. The new W-mass value leads to an estimate for the mass of the yet-undiscovered Higgs boson that is lighter than previously predicted, in principle making observation of this elusive particle more likely by experiments at the Tevatron particle collider at Fermilab."
Einstein@home
"According to Albert Einstein, we live in a universe full of gravitational waves. He suggested that the movements of heavy objects, such as black holes and dense stars, create waves that change space and time. We have a chance to detect these waves, but we need your help to do it!". This is how the project is introduced in their website. Similar to the SETI@home (Search for ExtraTerrestrial Intelligence) the project Einstein@home creates a network of home computers to analyze gravitational wave detectors data. The project is sponsored by the American Physical Society (APS).
