Separating the configuration and velocity measurements was pioneered by Euler in 1750s in his study of the dynamics of rigid body and fluid. This use of ‘nonmaterial velocity’ influenced greatly the development of mechanics. In 1904, Hamel extended...

Midpoint rule is a numerical integrator for ordinary differential equations. When used to simulate mechanical systems, it may reveal various structure-preserving features, such as symplecticity. The talk will discuss the variational origins and...
