They derive their name from the fact that they describe the conservation of some quantities of interest over time. In computational fluid dynamics (CFD), these quantities are usually mass, momentum and energy. For convenience we always refer to the conserved quantity as the "mass" in this ...
The measurement procedures are as follows; initially, two objects, one of whose mass is unknown, are at rest. Then, a repulsive force is generated between the objects so that their momentum change; the unknown mass is estimated from the ratio of their velocities. In the developed system, an...

Ok, so I remember reading that every conservation law has a corresponding symmetry (i.e. conservation of momentum is translational symmetry, conservation of angular momentum is rotational symmetry). Now conservation of energy is temporal symmetry (you can rewind the tape and it looks exactly the ...
Over this 2018-to-2021-time period we have seen international momentum build towards innovation and early commitment to action in the post-2021 period, plus better understanding of the tremendous effort required to “bend the curve” of biodiversity loss to be nature positive by 2030. The ...

As the law was refined, it was gradually transformed from a vague and abstract philosophical statement into an exact quantitative formula. On the other hand, some conservation laws appeared directly in a quantitative form. Such laws include the laws of conservation of momentum, angular momentum, ...
the reflexive turn in the discipline started gaining momentum during the 1970s and reached prominence in the 1980s and 1990s (Collins & Gallinat,2010; Salzman,2002). This was due to a complex confluence of influences, including concerns within the discipline surrounding ethnographic representation (...
