INTRODUCTORY LECTURES ON FLUID DYNAMICS
... Particle paths are lines traced out by “marked” particles as time evolves. In steady flow particle paths are identical to streamlines; in unsteady flow they are different, and sometimes very different. Particle paths are visualized in the laboratory using small floating particles of the same density as t ...

1 Path Integrals and Their Application to Dissipative Quantum Systems
... The most often used and taught approach to nonrelativistic quantum mechanics is based on the Schrödinger equation which possesses strong ties with the the Hamiltonian formulation of classical mechanics. The nonvanishing Poisson brackets between position and momentum in classical mechanics lead us t ...

The Lorentz transformation
... when the units of distance and time (and all other units that depend on them) are chosen appropriately. For example, one could work with seconds for time, and light-seconds for distance. (One light-second is equal to 299792458 metres). The only problem with this approach is that you must apply it co ...
