The canonical quantization of flux is performed. It is shown that according to the canonical flux quantization there must be a new uncertainty relation: e∆A m .∆x m ≥ ¯ h where A m and ∆x m ≥ l B are the electromagnetic gauge potential, the position uncertainty and the magnetic length, respectively. Other arguments in favour of this uncertainty relation are also discussed.

Using various model clocks it has been shown that the time-of-arrival cannot be measured more accurately than δt A > 1/E p where E p is the kinetic energy of a free particle. However, this result has never been proved. In this paper, we show that a violation of the above limitation for the transit-time, implies a violation of the Heisenberg uncertainty relation.

Three years after the completion of the next-to-leading order calculation, the status of the theoretical estimates of ǫ ′ /ǫ is reviewed. In spite of the theoretical progress, the prediction of ǫ ′ /ǫ is still affected by a 100% theoretical error. In this paper the different sources of uncertainty are critically analysed and an updated estimate of ǫ ′ /ǫ is presented. Some theoretical implicati...
