"Wavelet Processing for Wideband Scattering Function Estimation" by Penn State's Lora Weiss is the first paper in the inaugural volume of Acoustic Research Letters Online. Published by the Acoustical Society of America, ARLO (as the journal is more familiarly known) accepts papers in all fields of acoustics and can accommodate animated figures and audio clips.

The cracking of Germany's Enigma codes in World War II is the subject of an extensive online exhibit at Britain's Imperial War Museum. Among the topics covered by the multimedia exhibit is Colossos, the world's first programmable electronic digital computer, which helped crack even the most sophisticated German codes.

Jim Martindale's Reference Desk of online resources, which is hosted by the University of California, Irvine, is encyclopedic in its scope. Mathematics, physics, and chemistry are included, but so are fashion, pets, and business. Physicists might find especially useful the collection of calculators and science data tables.
