F2a: Support to PCCP

Check out the project news!

 

  • The Paris Centre for Cosmological Physics is a place of research, education and scientific exchanges in the field of cosmology, or more generally the physics of the Universe. It was created in February 2010 by George F. Smoot, when he was hired as professor of the University Paris-Diderot and he saw the opportunity to create a large Parisian centre dedicated to cosmology.

    Supported from the start by University Paris Diderot, CNRS/IN2P3 and the Paris Observatory, PCCP aims at developing a synergy between the Parisian laboratories (at present APC, LPNHE, LUTh, GEPI, LPTENS) to enhance the contribution of the French community to the rapidly developing field of cosmology.

    LabEx UnivEarthS contributes to the financing of some of the actions of PCCP such as the organization of workshops, visitors and postdoctoral programs, but also the training of high school teachers and the conception of a general public MOOC to share a scientific adventure on the frontiers of the knowledge.

    The Paris Centre for Cosmological Physics is a place of research, education and scientific exchanges in the field of cosmology, or more generally the physics of the Universe. It was created in February 2010 by George F. Smoot. The LabEx UnivEarthS contributes to the financing of some of the actions of PCCP such as the organization of workshops, visitors and postdoctoral programs, but also the training of high school teachers and the realization of a general public MOOC to share a scientific adventure on the frontiers of the knowledge.

     

    Teaching

    MOOC Gravity. Starting in 2015, the PCCP realized the English version of the MOOC: Gravity! This was not just a translation but a whole new course adapted to the British platform Futurelearn, significantly different in spirit from the French platform.   It is considered among the most successful MOCC’s worldwide, since it currently counts close to 100.000 inscriptions.

    MOOC activities 2017. The 3rd instalment of MOOC Gravity on FUTURELEARN platform was webcast from 30/01/2017 to 12/03/2017. Attending results were even better than the two previous sessions. According to the different levels of involvement there were 7912 Joiners, 4031 (51%) Learners,   1195 (29,6%) Social learners (present on the forum) and 1089 (27%) finished the whole course.

    Teaching the Universe. The program “Teaching the Universe” is continuing as well. There was a new session on November 16-­‐18 2016.  A session of “Teaching the Universe” was planned to be implemented in the “Evgenides Planetarium”, the main planetarium of Athens Greece, co-funded by the Evgenides foundation and the Labex.

    PW@APC 2.0. A clear asset of the program teaching the Universe is the demonstration setup reproducing the Penzias & Wilson experiment. We therefore rethought the setup and initiated computer and electronic investment in this project along with Maison des Sciences de Puisaye. We have purchased new equipment.

    Scientific activity

     

     

    Postdocs and scientific activity. Our scientific activities in the field of cosmology and gravitation continued actively, with a significant contribution of our PCCP fellows. Among them, Valerie Domcke (recruited by UnivEarthS) was awarded on October 12 2016 one of the L’Oreal‐UNESCO fellowships for Women and Science. She was also offered a 5‐year position from the Theory Group of the DESY laboratory in Hamburg (an excellent position, especially for a young candidate), which she accepted.

     

     

    Art and Science

     

    Univers 2.0 PCCP, and in particular P. Binetruy, has obtained funding from the Foundation Carasso (40 KE) to initiate an exploration, through a cross-reflection between artists and scientists, of the field that opened through the discovery of gravitational waves putting again at the centre questions on the nature of the space and time, their texture, the notions of origin and horizon, the role of information circulating in the Universe and its conservation or loss, the role of the human as observer and/or perturbator, more generally the nature of our embedding in the cosmos.

    This reflection will be initially carried out within the multidisciplinary team set up including very well-known artists internationally (Gorka Alda, Bertrand Lamarche, Liliane Lijn, Thomas Saraceno, Raymond Galle, Raphael Dallaporta). Philosophers also participate in the discussion (Heinz Wismann, Céline Flécheux). The work program includes for the time being artists residencies, workshops. On the scientist side, there were essentially some of the PCCP scientists and Marc Lachièze Ray.

    The project will culminate in two years with a restitution seminar, accompanied by an exhibition and a publication.
