Born in poverty on the outskirts of Barquisimeto in the Venezuelan interior, Gustavo Dudamel has become what Simon Rattle calls "the most astonishingly gifted conductor I have ever come across."

The Grolier Club has mounted an exhibition that takes miniature books bigtime.

Why, in loudspeaker reviews, is impedance measured (assuming that the magazine in question bothers to measure anything)? Generally, for one principal reason only: to establish whether the speaker presents an "easy" or a "difficult" load to its partnering amplifier. In the design context, much more information can be extracted from a graph of speaker impedance vs frequency—such as details of the bass alignment, and indications of internal or structural resonances that can be difficult to identify by acoustical measurements. But for a magazine audience, the principal interest in a loudspeaker's load impedance lies in gaining some indication of its compatibility with a given amplifier.

When audio designer Ken Shindo was a little boy, his father kept an enormous collection of 78rpm records in their home in Tokyo. During the final days of World War II, the Japanese authorities did their best to evacuate the city, but the elder Shindo was steadfast: He refused to leave, for fear that the records would be gone when he returned.
