Articles:

Ancient Stardust in the Laboratory

As it collapsed to form the Solar System, material in the solar nebula was churned up and homogenized. But not everything was lost in the mix... -- Thomas J. Bernatowicz and Robert M. Walker

The Foundation of the Silicon Age

The transistor was the product of basic research with a clear technological goal, but although the new technology was anticipated, its revolutionary impact was not -- Ian M. Ross

The Moses of Silicon Valley

How did the epicenter of the semiconductor industry come to be located in California, a continent away from New Jersey, where the transistor was invented and most of the fundamental semiconductor technology was developed? -- Michael Riordan and Lillian Hoddeson

Search and Discovery

Work on atom trapping and cooling gets a warm reception in Stockholm. An atom at room temperature zips around at thousands of kilometers per hour. A hit by a single photon barely fazes it. Yet somehow, researchers have harnessed radiation forces to slow atoms to a few centimeters per second and trap them in place. For that feat, this year's Nobel Prize in Physics has been awarded.
       ** An article on this work by two of the laureates, and related links

Optical frequency measurement is getting a lot more precise. A new trick for the repeated halving of optical frequency intervals now permits the measurement of optical atomic transitions with unprecedented accuracy.

New results suggest x-ray emission is a common property of comets.
      The brandisht Sword of God before them blaz'd
      Fierce as a Comet; which with torrid heat,
      And vapour as the
Libyan Air adust,
      Began to parch that Temperate Clime . . .
-- J. Milton, Paradise Lost

Physics Community

Los Alamos's new director must get stockpile stewardship in gear, grapple with locals' concerns. Depending on one's point of view, John Browne is seen either as bringing a good mix of experience and personality to his new job as Los Alamos's director, or as being too entrenched in the lab to make changes.
