The way I understand it, they can be thought of as terms of uncertainty for time and energy, which are inversely related. That is to say, if you measure the Energy to a high level of certainty, the level of uncertainty will be high as well.
Looking back in my text describing the relation, it...
Homework Statement
In special conditions, it is possible to measure the energy of a gamma ray photon to 1 part in 10^15. For a photon energy of 50 keV, estimate the maximum lifetime that could be determined be a direct measurement of the spread of photon energy.
