Uncertainty, Reproducibility, and Testing of a Hypothesis Sources of uncertainty: - No units , bad units , inconsistent units - Uncertainty in the design of the experiment , -i.e . when is the cup of macaroni really full, are all cups of the same kind, etc. - Uncertainty in the measurement, -i.e . counting errors ; experimental resolution . - Noise, or other irregular, unknown forces are important , - i.e. in a coin flip: high sensitivity to noise, history, context = chaos
