摘要:

Ongoing frustration with the trivial role science has played in the current congressional elections, combined with a deeper sense that the Bush administration is ignoring and misusing science, has led a group of prominent scientists to form a national political advocacy organization with the intent of influencing elections and government policy.

摘要:

Why does food cook faster in a pressure cooker? Why do tires squeal on braking? Can a rainbow be circular? These and 47 other questions—and their answers—form the core of “Science in Public Areas,” a public‐education campaign unveiled on 9 October by the European Physical Society.

摘要:

Amid efforts by the American Physical Society to determine how best to handle the changing nature of scientific publishing, its largest enterprise, two of its three operating officers are stepping down from their longtime posts.

摘要:

A recent report by the American Institute of Physics tracks US physics and astronomy enrollments and degrees at all levels and looks at the representation of women, minorities, and non‐US citizens.

摘要:

As of about a year ago,764 distinct college‐level physics departments existed in the US. Of those, a whopping 513 are at institutions whose highest degree offered is a bachelor's. The vast majority of the schools are liberal arts colleges—by which we mean institutions that focus primarily on undergraduate education, rather than on graduate education and research; this category includes some of the smaller state universities and a few colleges with small graduate programs. Liberal arts colleges represent a significant job market, one that many PhD‐level physicists aspire to join.

摘要:

The discoveriesof general relativity and quantum mechanics began a revolution in physics. But the problem remains of completing the revolution with a theory of quantum gravity that joins those two pillars of modern physics. To have a chance to succeed, the new theory must not only make sense, it must make new predictions that can be tested by doable experiments. Physicists have made a great deal of progress in achieving the synthesis and have even proposed new experiments. That progress is the subject of this article.

摘要:

Astronomyis today in a golden age, one that began approximately in the early 1990s with the launch of theHubble Space Telescope. TheHSTand its counterparts, such as theSpitzer Space Telescope, have produced stunning images. Earth‐based astronomy at optical, IR, and submillimeter wavelengths has achieved comparable progress. The most striking advance has occurred in interferometry—especially optical interferometry, which produces spatial resolutions previously unimaginable in single‐aperture telescopes. The twin Keck telescopes on Hawaii's Mauna Kea, for example, are now referred to as the Keck Interferometer. Other Earth‐based instruments and techniques have likewise made enormous progress with, for example, the discovery of dozens of extrasolar planets.
