Neutrinos dans la neige

Le nouvel observatoire IceCube, conçu pour détecter les neutrinos, est enfin achevé. Installé en Antarctique, cet instrument de physique des particules est enfermé dans 1 km3 de glace, près de la station américaine Amundsen-Scott.

IceCube est un projet de la Fondation nationale pour les sciences (National Science Foundation) et de l’Université de Wisconsin-Madison, aux États-Unis. Des universités belges, allemandes et suédoises participent au projet. Plus largement, le Canada, le Japon, la Nouvelle-Zélande, la Grande-Bretagne, la Suisse et la Barbade sont associés à l’analyse des données du nouvel observatoire.

Santa: A Claus-et physicist

Several professors in the school's Department of Mechanical and Aerospace Engineering recently asked their students to explore the aerodynamic and thermodynamic challenges of delivering gifts to millions of children worldwide in a single night from an airborne sleigh.

The results, posted at web.ncsu.edu/abstract/tag/science-of-santa, posit that Santa Claus is a brilliant engineer and physicist.

Possibility of the Space Propulsion System Utilizing the ZPF Field

AIP Conf. Proc. 1103, 194 (2009)
Published online: March 16, 2009
DOI: 10.1063/1.3115495

According to the gravity theory proposed by H. E. Puthoff, gravity is a form of long-range van der Waals force associated with the Zitterbewegung of elementary particles in response to zero-point fluctuations (ZPF) of the vacuum and the inertia mass is arisen from the interaction with the vacuum electromagnetic zero-point field. From the standpoint of the ZPF field theory, the author studied the possibility of the space propulsion system, which is based on interactions between the zero-point field of the quantum vacuum and high potential electric field. By the theoretical analysis, it is considered that impulsive high potential electric field can produce a sufficient momentum for the spacecraft, which would permit interstellar travel instead of conventional chemical rockets.
