# Experimental tests of Bertrand’s question and the Duhem–Quine problem

@article{Liu2019ExperimentalTO, title={Experimental tests of Bertrand’s question and the Duhem–Quine problem}, author={Zhenning Liu and Charles S. Adams}, journal={European Journal of Physics}, year={2019}, volume={40} }

In this paper we report on an experimental test of Bertrand’s question on the probability to find a random chord drawn inside a unit-radius circle with length greater than 3 . In an experiment performed by tossing straws onto a circle, we confirm a theoretical prediction that the answer depends on the ratio of the circle diameter, 2R, to the straw length, L, and that the special case, which follows from rotational and translation invariance using integral geometry, is only obtained in the…
