Causality, Determination and such stuff. The standard philosophical prejudice is that given an accurate enough account of the position of the box and a given ball, a competent physicist will be able to tell us which of the bins across the bottom the ball will land in.
And in this sense the path of the ball is determined.
But of course no one could determine the final resting place of the ball. Even the smallest error in the initial positions will be magnified until it throws out the calculations.
Anscombe wrote this in a time of only nascent chaos theory, which could only serve to amplify her point.
The notion that the universe is determined fails. — Banno
Your assumption and the article's assumption is that the Universe is simple enough for extremely intelligent humans to predict an extremely complicated universe. This article was written by a simpleton. Much of quantum physics is disagreed upon by many physicists. Not all Quantum Physicists agree on Quantum Physics. People very often assume that Theoretical Physicists always make the right judgements.
If i or you don't 100% understand the math and the lab results behind a scientific theory, you and i (right/wrong/or indifferent) are putting our faith in scientists. Belief, Faith, and partial understanding of a concept are all forms of gambling.
