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

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

e. In 1918, when Fermi graduated from high school in Rome, the possi- bilities open to a brilliant young scientific mind were far less constrained. Quantum mechanics had just been born, new ideas were everywhere, and the rigorous mathematics necessary to deal with these ideas had not yet been developed

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
