@ombialik Bruno Grossi et al. (2014) provide interesting evidence suggesting that #shifting the #centerofmass using an artificial #tail causes #birds to exhibit movements reminiscent of non-avian #theropods (#dinosaurs).

A #barycenter is a dynamical point, not a physical object. It is an important concept in fields such as #astronomy and #astrophysics. The distance from a body's #CenterOfMass to the barycenter can be calculated as a #TwoBodyProblem.

Self-Powered Top Spins For Hours

The meaning of Inception’s ending famously revolves around a top which spins forever in dreams, but in real life comes to a stop like any other top. Any other top, that is, except for [Aaed Musa]’s…
