theory can be reformulated in terms of old-fashioned configuration spaces and ‘indivisible’ stochastic laws, without a fundamental role for Hilbert spaces, wave functions, density matrices, or even the complex numbers. After reviewing this axiomatically simpler
and more transparent formulation, I will argue that it does not suffer from some of the major foundational problems of textbook quantum theory, like the measurement problem, and that it deflates various exotic claims about superposition, interference, and
entanglement. I will also use this new formulation to introduce a microphysical definition of causal influences, which can be used to exploit loopholes in the existing no-go theorems, including Bell’s theorem, with potentially significant consequences for
causal locality.</span></p>

of the mystery of time arises from the asymmetry of past versus future: not only asymmetries themselves, such as the apparent ‘openness’ of the future and ‘settledness’ of the past, but the ‘passage’ of time – ‘turning’ open future into settled past. In turn,
much of the difference between open and settled lies in the knowledge asymmetry: that we know so much more, so much better, about the past than future. In
<i>Time and Chance</i> David Albert proposes that the asymmetry arises because knowable particular matters of fact are just those made likely by physical law, given uniform probability over states compatible with the ‘current surveyable condition’ and an asymmetric
‘Past Hypothesis’. This paper presents an ‘Information Gathering and Utilizing System’ as a model of memory, in order to better understand the physical nature of the asymmetry. I will argue that we can in fact know more about the past than Albert’s condition
allows.</span></p>
