irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

Patterned structure of remote phosphor for phosphor-converted white LEDs.

High efficiency white light-emitting diodes with superior color-mixing have been investigated. It is suggested that the patterned remote phosphor structure could improve the uniformity of angular-dependent correlated color temperature (CCT) and achieve high chromatic stability in wider operating current range, as compared to the conventional remote phosphor coating structure. In this experiment...
