“Sheer idiocy to say that experimental research is Nordic-Germanic and that rational research, on the contrary is of foreign extraction! We would then have to resolve to number Newton and Leibniz among the “Jews.”

Writing against science, math, calculation, Heidegger makes this little antisemitic joke.

He goes on to add, “It is precisely the projection of nature in the mathematical sense that constitutes the presupposition for the necessity and possibility of “experimentation” as measuring.”
