The coughing during the discussion of energy states is a trifle annoying. Physics students among the esteemed viewership - is the point that is being made that absolutely defined energy states are perfectly stable, whereas all real particles with energy are is constantly unstable energy states, thus there must be some uncertainty as to which energy state they are in?

@Ferrus91 I agree that the problems with the audio equipment during this lecture become very distracting while trying to concentrate on the subject matter. I will endeavour to persevere. Cough, choke!
Has anyone examined the effect where when one person coughs it sets off a cascade of sympathy coughs? There could be PhD in there.
