The immutable verities of grand physical laws

Galvanometer

“The design and manufacture of scientific instruments has undergone a radical transformation in the last 30 years, achieving what might be described as the democratization of accuracy. Levers, pinions, wheels, and linkages have given way to microprocessors that read data at exquisite levels of sensitivity and reveal it instantly on digital displays. This transformation has affected our lives far beyond the laboratory, but to my eye the gains have been accompanied by losses.”

That history came alive Saturday as one of these surviving 19-ton
machines steamed into action in Brunswick.
