 The Importance of Accuracy

In 1905, a physicist measuring the thermal conductivity of copper would have faced, unknowingly, a very small systematic error due to the heating of his equipment and sample by the absorption of cosmic rays, then unknown to physics. In early 1946, an opinion poller, studying Japanese opinion as to who won the war, would have faced a very small systematic error due to the neglect of the 17 Japanese holdouts, who were discovered later north of Saipan. These cases are entirely parallel. Social, ...

 Aristotle's Attempt to Categorize Motion

11 Now everything that changes place is moved either by itself or by something else. In as many of these as are moved by themselves, it is obvious that the moved and mover are together, since the first mover is present in them, so that nothing is in-between. But as many as are moved by other things must come about in four ways, for there are four kinds of change of place by means of something else: pulling, pushing, carrying, and whirling. For all motions with respect to place lead back to th...
