Polls apart

But what made him so important in the history of science was his further insight that mathematics, in order to reveal the laws of nature, had to be empirically tested. Mathematical formulae described what he thought would happen; he had to clamber up the leaning tower of Pisa and drop the two balls to convince us that objects of different masses fall at the same speed. I am not sure that most modern pollsters have taken Galileo’s second insight fully on board. The modern pollster tends to be in love with his model.
