A new galvanometer-based laser processing system reported in Engineering integrates full-in-situ imaging and machining without requiring coordinate conversion or calibration, offering a streamlined ...

A chance "eureka moment" by a Scottish physicist solved a problem that had plagued the transatlantic cable -- and made a lord out of the man who had the insight. One of the fundamental problems of ...

ATTENTION has recently been drawn more than once (notably by Sir William Thomson, and by Mr. W. H. Preece and Mr. Kemp) to the advantages offered, in certain cases of the use of the ...

Discovery and understanding of electromagnetic induction are based on a long series of experiments carried out by Henry and Faraday. If North-pole of a bar magnet is pushed towards the coil, the ...

The creation, development, and implementation of today's high-speed circuits and passive interconnections requires a good understanding of how electrons, traveling through a medium, behave at various ...
