Weber's Law Modeled by the Mathematical Description of a Beam Balance proposes that the mathematical mechanics of a beam balance can actually model how human sensory and receptor systems perceive changes in stimuli.
Determination of the Gravitational Constant with a Beam Balance describes using a mass comparator to measure the gravitational force of 13 tons of mercury, refining the accuracy of the Newtonian gravitational constant beam balance
It features a 50-cm aluminum arm and uses an interferometric read-out system to achieve extreme precision. Weber's Law Modeled by the Mathematical Description of
