Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...
A 250-day experiment using a ring laser achieved unprecedented accuracy in measuring Earth's axial wobble (nutation and precession), surpassing previous gyroscope and ring laser technologies by a ...
Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...
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 ...
An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) ?ofia Chrobáková, a doctoral student at the IAC and the University of La Laguna (ULL), and Martín ...
The northern stars turn around Polaris and the North Celestial Pole in a composite spanning multiple hours during a single night in the summer of 2014. The bright point at the center is Polaris, our ...
Last November, Quantum Design and NanoMEGAS invited industry and research professionals to learn more about the theoretical and practical applications of Precession Electron Diffraction (PED).
