Super-B factory takes shape As the LHC continues with its record-breaking 2016 performance, a new “super-B factory” designed to search for new weak interactions in the flavour sector – Belle II at SuperKEKB – is nearing completion at the KEK laboratory in Japan. The inauguration of the MAX IV light source in Sweden, meanwhile, showcases another machine milestone: a novel lattice design that produces the brightest X-rays on Earth. Sticking with the accelerator theme, we also report on an attempt to use a storage ring to pinpoint the electric dipole moment of particles. Finally, the CMS collaboration describes how a new trigger system is taming the harsh collision environment of LHC Run 2, while CERN considers how to deal with the computing and data challenges presented by its major machine upgrade, the HL-LHC.

We therefore need a dedicated “Science Cloud” instead. CERN has already started to think about the Sophia Elizabeth Bennett Elizabeth Sophia parameters for such a facility. Zenodo, for example, is a future-proof and non-proprietary data repository that has been adopted by other big-data communities. The virtual nature of the technology allows various scientific disciplines to coexist on a given infrastructure, making it very attractive to providers. The next step requires co-operation with governments to develop computing and data warehouses for a Science Cloud. CERN and the broader particle-physics community have much to bring to this effort. Just as CERN played a pioneering role in developing Grid The CERN data centre is the By Eckhard Elsen computing to meet the needs of the LHC, we can heart of the Worldwide LHC contribute to the development of the Science Cloud Computing Grid, but the Steam once powered the world.

Benedict XVI in the garden of the Basilica di Santa Maria degli angeli e dei Martiri with the statue of “Galilei Divine Man” donated to the Basilica by CCaSt of Beijing. he great Galileo said that God wrote the book of nature in the form of the language of mathematics. He was convinced that God has given us two tbooks: the book of Sacred Scripture and the book of nature. and the lan - guage of nature – this was his conviction – is mathematics, so it is a language of God, a language of the Creator. Encounter of His Holiness Benedict XVI with the Youth , St Peter’s Square, thursday, 6 april 2006. n the last century, man certainly made more progress – if not always in his knowledge of himself and of God, then certainly in his knowledge of the macro- Iand microcosms – than in the entire previous history of humanity. ... Scientists do not create the world; they learn about it and attempt to imitate it, following the laws and intelligibility that nature manifests to us. the scientist’s experience as a human being is therefore that of perceiving a constant, a law, a logos that he has not created but that he has instead observed: in fact, it leads us to admit the existence of an all-powerful Reason, which is other than that of man, and which sustains the world.
