Rockets and Feathers in the Laboratory Ralph - C Bayer and Changxia Ke

Consumers often complain that retail prices respond faster to increases in wholesale prices than to decreases. Despite many empirical studies confirming this “Rockets-and-Feathers”phenomenon for different industries, the mechanism driving it is not well understood. In this paper, we show that, in contrast to the theoretical prediction, asymmetric price adjustment to cost shocks, as well as pric...

Congreve’s efforts to imitate Indian war rockets used against the British in Mysore are set within a number of local and global contexts that saw increasing attempts by Europeans to imitate eastern pyrotechnics w...

Photon rockets and gravitational radiation

The absence of gravitational radiation in Kinnersley’s “photon rocket” solution of Einstein’s equations is clarified by studying the mathematically well-defined problem of point-like photon rockets in Minkowski space (i.e. massive particles emitting null fluid anisotropically and accelerating because of the recoil). We explicitly compute the (uniquely defined) linearized retarded gravitational ...

Nuclear Powered and Reactionless Rockets

| We consider using emissions from radioactive atoms as the \exhaust" of a \rocket" for space propulsion. The \alpha rocket" consists of a thin lm of alpha emitting atoms on an inert backing lm of thickness 40 microns. It achieves speciic impulse values in the range 5 10 2 ; 10 3 ] km/second. It seems likely to be practical. By using 254 Cf and 250 Cm, which instead decay by spontaneous ssion, ...
