"The Higgs boson ... is the key to understanding why mass exists and how atoms are possible. After billions of dollars and decades of effort by more than six thousand researchers at the Large Hadron Collider in Switzerland--a doorway is opening into the mind-boggling world of dark matter and beyond. Caltech physicist and acclaimed writer Sean Carroll explains both the importance of the Higgs boson and the ultimately human story behind the greatest scientific achievement of our time"--Publisher.

278 páginas.. La física cuántica propone, sobre una base científica, el concepto de un universo en el que cada partícula está conectada con todas las demás a través de un enlace que supera todas las leyes de la física clásica. En este contexto, todas las cosas convergen en un gran proyecto de evolución cósmica, el "Unus mundus". Hoy, muchos científicos conocidos suscriben la "teoría antrópica", según la cual el universo no nació por casualidad, sino que fue creado exactamente con las características que posee para albergar vida inteligente. Los últimos descubrimientos...

Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized...
