Vinen's vibrating wire experiment detected quantized vortices in superfluid 4He, with the anticipated circulation quantum h/m. In addition to this main result, Vinen used his data propose other properties and behaviors of vortices, which are revisited here. Subsequent work confirmed that non-quantized values occur when cover only part wire's length, size covered section can change easily. Any m...
