Featuring Professor Phil Moriarty from the University of Nottingham

Note from Phil: A crude and basic introduction to the idea of error bars is covered in the video. No mention is made of, for example, the effect of repeated measurements on reducing the standard error, adding in quadrature, or of confidence limits. For a slightly more detailed discussion of experimental uncertainty, see youtu.be/ThP51oPttS0
