ese non-localities compromise the interpretation of experiments underway in which (1) is tested, such as in observations of gamma ray bursts by the Fermi satellite[5]. The present paper has two aims. The first is to study the description of processes in which gamma rays are emitted and detected, as i

s about how the principle of the relativity of inertial frames can be made consistent with the existence of a minimal length scale, taken to be the Planck length, Ip[1, 2, 3]. It may also be seen as making possible a maximum momenta for an individual particle. Over the almost decade since it was first

conflict with the observed locality of interactions in nature. These considerations may be relevant for phenomenology such as observations by the Fermi observatory, because at leading order in 4 x distance there is both a direct and a stochas- tic dependence of arrival time on energy, due to an addit

(DSR) the action of the Lorentz group on momen- tum eigenstates is deformed to preserve a maximal momentum or minimal length, supposed equal to the Planck length, to, = VO. The classical and quantum dynamics of a particle prop- agating in ti-Minkowski spacetime is discussed in order to examine an appare

d my own attitude and approach to the field, as well as my own understanding of it. I only wish I were as talented as either of them. Born in 1901, Fermi died at the age of fifty-three of cancer, perhaps brought on by his work on radioactivity. In 1954, when he died, he was nine years younger than I

k had helped pioneer the quantum revolution by resolving the paradox of the spectrum of radiation emitted by atomic systems. So it was fitting that Planck should indirectly help resolve the paradoxical makeup of the nucleus. While he didn't himself spearhead the relevant research, he recognized the ta
