"Are you sure? The quest for error bars in nuclear 
theory"
Perhaps the greatest benefit of the recent 
advances in ab initio nuclear
theory is the possibility to make predictions with 
meaningful
uncertainties. This is especially valuable for 
quantities that are
difficult or impossible to access experimentally, 
such as those that
arise in astrophysics or in searches for physics 
beyond the standard
model. However, just because uncertainty 
quantification is possible does
not mean that it is easy. In many cases, converged 
ab initio
calculations of the quantities of interest, in the 
nuclei of interest,
have only recently been achieved and efforts at 
rigorous uncertainty
quantification are still in early stages. I will 
discuss some
developments which enabled the ab initio 
calculations to be done at all
and some initial efforts to make good on the 
promise of error bars for
nuclei.
