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 ...

La nutation est un phénomène astronomique lié à la rotation d'un astre, en particulier la Terre, et plus précisément à l'oscillation périodique de l'axe de rotation de ce corps céleste. Ce terme ...

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 ...

Earth’s rotation dynamics are influenced by a range of internal and external factors, with Free Core Nutation (FCN) standing out as a key phenomenon. FCN arises from the slight misalignment between ...

1. A long series of observations on the elongating shoots of Pinus sylvestris showed that during the elongating period the new shoots are subject to nutations, which are caused by differentiation of ...
