Precise measurements of the dissipation and resonant frequency of a torsion pendulum reveal an anomaly in the inferred viscosity and normal density of liquid $$^3$$ He near the superfluid transition. We present an argument that the anomaly originates

In this letter we employ recent results on gravitationally induced parity violation with a rotating torsion pendulum whose test bodies are quartz enantiomers (Zhu et al. in Phys Rev Lett 121:261101, 2018) in order to estimate, using a simple model, H

Torsional properties of single fibers have considerable effects on the performance of fabrics. A new torsion tester with high resolution is developed based on the torsion-balance method and the autocollimation principle for measuring the torsional pr

In absolute gravimeters, rotation of the falling body leads to inaccurate measurement of gravity. The error can be minimized by collocating the center of mass (COM) of the body with its optical center (OC). A method to measure the distance between th
