Articles:

A Nobel Tale of Postwar Injustice

Recently released Swedish documents reveal why Lise Meitner, codiscoverer of nuclear fission, did not receive the 1946 physics prize for her theoretical interpretation of the process -- Elisabeth Crawford, Ruth Lewin Sime and Mark Walker

Nonclassical Excitation in Spectroscopy with Squeezed Light

An experiment with squeezed light has demonstrated a new type of nonclassical effect: Correlated two-photon absorption can produce a two-photon excited population with a linear intensity dependence -- Zbigniew Ficek and Peter D. Drummond

Information Warfare: A Brief Guide to Defense Preparedness

Information systems play an important role in society, so threats to their security should be taken seriously---but there is no need to panic -- Martin C. Libicki


Departments:

Reference Frame

Singularities and blowups -- Leo P. Kadanoff

Search and Discovery

Experiments find hysteresis and precursors in the stick-slip friction of a granular system. Do laboratory studies of friction in a variety of systems have similar behavior?

Hipparcos parallax data may reconcile ages of globular clusters and the universe. The number of stars for which we have accurate distances has suddenly grown a hundredfold. It's already affecting estimates of the age of the cosmos.

Infrared laser illustrates another way to achieve gain. Thanks to an innovative design, researchers have made an infrared semiconductor laser whose wavelength can be electrically tuned.

Radio telescope in space maps quasar jet.
