anomalous spinning

formatting link

A symmetric harnessed gyroscope accelerated to a given spinning
frequency takes different time periods to stop, depending on the
direction of previous spins. For repeated alternating, anticlockwise
and clockwise spinning, the rotation period in both directions
significantly increases, which is not the case when the gyroscope is
repeatedly rotated in the same direction. Using the measurements it was
observed, that the time of gyroscope's rotation was significantly
lengthened or shortened, what indicates that it either increased or
decreased the movement resistance of the gyroscope. The presented
experimental results suggest the existence of anomalous movement
resistance and demonstrate that a fixed spinning gyroscope displays
unusual history-dependent movement resistance effects. The effect is
real, large, reproducible and does not follow from experimental errors.

The protocol chosen differentially warms the wheel and its boundary layer, leading to reduced air resistance in the reversing case
