THE following account of a simple experiment may be of interest to some of the readers of NATURE. The common peg-top and tee-totum are commonly referred to as affording a good example of the ...

image: An international team of scientists has managed for the first time to observe the 'nutation' of spins in magnetic materials (the oscillations of their axis during precession). The measured ...

Precession-driven fluid dynamics concerns the intricate motions arising when a rotating body experiences a slow, conical motion of its spin axis, a phenomenon that is pivotal in both geophysical and ...
