We will discuss the up-to-date theory and review recent experimental results related to understanding the proton radius puzzle, which is the conflict between measurements of the proton radius using muons as compared to measurements using electrons. There are signs that recent electron results are coming closer to the muonic ones, but there is not yet universal agreement, and disagreement leaves open possibility of a beyond the standard model solution.
