United We Serve: A Call To Universal Jewish Service

We have reached a turning point in American Jewish history. Now that large segments of our community are living successful, integrated lives, we have an opportunity to align ourselves behind service to enrich Jewish life and to effect prophetic change in the world. In Pirke Avot (Ethics of the Fathers), Rabbi Tarfon admonishes us, You are not obliged to finish the task, neither are you free to desist from it. The usual interpretation is that our task is bigger than any of us in terms of the quantity of work that must be done. Rabbi Tarfon\u27s dictum, however, also refers to the complexity of the task. We come to understand the critical interdependence of individuals, each bringing their own skills and varied perspectives to accomplish our people\u27s role in the covenant

Sparking a Renewed Jewish Commitment to Service

Where do Jews stand in relation to service and what might a Jewish commitment to service look like? By reflecting on historical Jewish understandings of service, we hope to gain perspective on the present and the need to rejoin our concepts of God, service, and worship. Such explorations can spark a radical transformation of our social and communal norms

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t
