Perhaps the most interesting article in this issue is 'Significance of Electromagnetic Potentials in the Quantum Theory.' It highlights the Aharonov-Bohm effect, actually predicted nearly 10 years earlier by Ehrenberg and Siday, but here rediscovered. New Scientist named this effect as one of the 'seven wonders of the quantum world.'
