# Computation is the Window to the Abstract A [Computation](Computation.md) or a proof is a [Physical Process](Physical%20Process.md) in which objects such as computers or brains physically model or instantiate abstract entities like numbers or equations, and mimic their properties. It is our window on the [Abstract](Abstractions.md). It works because we use such entities only in situations where we have good explanations saying that the relevant physical variables in those objects do indeed instantiate those abstract properties. --- Date: 20241230 Links to: [Beginning of Infinity](Beginning%20of%20Infinity.md) pg 188 Tags: References: * []()
