Features

God’s Rays
The physicist’s quest for understanding is not the only way to raise the level of our existence and give our lives meaning — Bryce DeWitt

Computational Science Demands a New Paradigm
The field has reached a threshold at which better organization becomes crucial. New methods of verifying and validating complex codes are mandatory if computational science is to fulfill its promise for science and society — Douglass E. Post and Lawrence G. Votta

How to Popularize Physics
An outreach effort can combine an eager audience, a favorite topic, and a preferred medium of expression to achieve a wonderful teaching experience — Elizabeth H. Simmons

Search & Discovery

An Array of Cherenkov Telescopes Yields the First Resolved Image of a Celestial Gamma−Ray Source
Imaging with TeV photons provides the most direct evidence yet that cosmic rays originate in the shock fronts of supernova remnants.

New Study Correlates Mantle Melting to Mid-Ocean Ridge Segments
Variations found in the composition along a stretch of exposed mantle on the Arabian peninsula offer fresh evidence for the link between the length scale of ridge segments and Earth's convection process.

Issues & Events

R&D Budget Brings Modest Increases to Most Civilian R&D; NSF Takes a Hit
As in the past three US budgets, defense and homeland security received most of the federal R&D dollars. With the federal deficit at $413 billion and climbing, most budget experts expect science funding to get worse before it gets better.

Texas A&M Reaches for Stars
As part of a campus-wide explosion in faculty numbers, the physics department at Texas A&M University in College Station aims to launch a topnotch astronomy program.

Hard Push for Soft-Matter Research at NYU
The Creation of an interdisciplinary and international Center for Soft Matter Research makes physics the first field to get a boost from New York University's $2.5 billion expansion plans.

Activities Large and Small Set for International Year of Physics
The World Year of Physics kicks off this month with a conference at the Paris headquarters of the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Barring ITER Site Consensus, Europe Will Forge Ahead
Agreement on a site for ITER remains elusive, but in late November, the European Union's council of ministers gave its seal of approval to building the international fusion energy test reactor in Cadarache, France.

Oddone Named to Head Fermilab
Physicist Pier Oddone has been named as the next director of Fermilab and will take the post on 1 July 2005.

Cold Fusion Gets Chilly Encore
Claims of cold fusion are no more convincing today than they were 15 years ago.

Physics Today cover "World Year of Physics"
medium | large

Cover: If you were plummeting toward the old market square in Tübingen, Germany, at 90% the speed of light, this is what you'd see. Lorentz contractions and the finite travel time of light produce a hyperbolic distortion that tilts the buildings outward. The image is part of an interactive computer simulation that is joining exhibitions around the world about Albert Einstein. For a taste of the many activities planned for the World Year of Physics, turn to page 28. For more on Physics Today’s plans, turn to page 10.
