The Economist on homeopathy in Germany:
IT MAY not be as ancient as acupuncture, but homeopathy is the closest thing Germany has to a native alternativemedicine tradition.

John Oliver’s Last Week Tonight on: “Journalism”
 German statistical office (in German): “Promovierende in Deutschland“:
 They held a survey with 20,000 professors and 20,000 PhD students in Germany.
 There are currrently 33,154 professors in Germany that can graduate a PhD student (“Promotionsrecht”).
 The immense number of PhD students (“Promovierende”) is 196,200 of which 111,400 are enrolled at an university. And 99% of those finishing their PhDs are those that are enrolled at an university. (These numbers are obviously inflated by German peculiarities such as counting medical doctorates as PhDs.)
 11% of professors have no PhD students, 50% have 15 students and 3 percent have more than 20 PhD students. The average is 6 students per professor and that ratio is highest for the engineering subjects.
 44% (\(= \frac{87,000}{196,200}\)) of PhD students are women.
 The modal age is 29.
 15% are nonGerman.
 23% of students are in structured programs, 23% of students are doing a cumulative dissertation (economics PhDstyle).
