 Friend and Molinini 2015 generalize the question of mathematical explanations of scientific phenomena to two further questions: are there wholly (as opposed to partial, as in the standard cases such as the cicada case) mathematical explanations of scientific phenomena? And: are there wholly mathematical explanations of scientific theories? They answer in the affirmative using as a case study the work on the axiomatization of relativity theory carried out by Hajnal Andréka, Judit Madarász, István Németi and Gergely Székely.
