In his blog Pepijn Van Erp sits as judge of all matters in physics, mathematics and medicine while he has attempted and failed for some years to get a master degree in mathematics. Pepijn calls himself Drs. (Doctorandus) in Wikipedia and on his website. According to Dutch legislation, the Dutch doctorandus degree is equivalent to the MA or MSc degree in English-speaking countries so Mr. Van Erp is giving himself a title that he does not have. So far he has not proven that his tile is in fact legitimate.
